Additionally, a power releasing mechanism is provided for the winch mechanism for preventing toy parts from being damaged when a winch wire is excessively rolled up.

Abstract: In a color separation image reproduction system, the unrecorded area of a photosensitive film is minimized by providing for recording the color separation images on the film in arbitrarily selectable order and position. Only the necessary color separation images are recorded on the film, so that film area is not recorded with unnecessary images. Different size images are accommodated in the inventive system by a pulse generation circuit which, by sectioning of a pulse sequence representing a scanning cycle, determines appropriate order and position of the images.

Abstract: A speed setting arrangement for a sewing machine comprises a permanent magnet mounted for unitary rotation with the foot pedal of the sewing machine, and a magnetic sensor including a plurality of magnetoresistors arranged in pairs to form a bridge circuit on a stationary plane spaced a distance from the plane of rotation of the magnet. The magnetic sensor provides an output signal which is exclusively a function of the magnetic orientation of the magnet and thus serves as a valid indication of the amount of pedal depression. An analog to digital converter is coupled to the magnetic sensor to convert its output into a digital signal for speed control purposes.

Abstract: A coin discriminator comprises photoreceivers along a vertical drawn from an infed coin run chute whereby screening and illuminating the photoreceivers from a photoemissive source permit coin diameter identification. Two coils on either side of the chute detect the coin alloy. Coin thickness is determined using a stepshaped transversal section across the chute track where the step risers lie opposite the photoreceivers which transmit a signal word identifying the infed coin diameter and thickness. This signal word is compared with memorized words representative of acceptable coin dimensions. If the dimensions are acceptable, a combination of impedances in a bridge circuit incorporating the coils is selected in terms of the alloy corresponding to the acceptable dimensions. If the bridge balances for this combination as the coin rolls between the coils, the coin is accepted.

In each bundle the seizure of an outgoing channel is made by scanning and searching a free channel in the bundle.

Abstract: An energy beam, particularly a neutrino beam or an optical radiation beam, is detected by irradiating a material with the beam in the presence of electromagnetic fields. The material is such that the beam is coherently scattered thereby, and the coherent scattering of the beam causes coherent stimulated emission of radiant energy fields in the material. Electric or magnetic fields adjust the scatterer energy levels so that energy and momentum are conserved overall, and for detection. The neutrino beam causes derivation of RF photons which are detected by a radio receiver. Alternatively, the neutrino beam irradiates a bulk material having nuclei with non-zero spin and non-zero magnetic moments and with sufficient stiffness to recoil as a single entity after absorbing momentum from each neutrino in the beam.

Abstract: In a noise reduction circuit, a sampling pulse is generated for opening a switch in time-coincident relationship with a signal portion which is affected by a noise impulse. During tracking modes the signal is passed through the switch to a junction between a capacitor and a noninverting amplifier to charge the capacitor to the level of the signal. During a sampling mode the switch is open to block the signal. A feedback circuit having plural time constant values is connected between the output and input of the amplifier to provide primary and secondary differentiation of the output signal of the amplifier. The feedback circuit is disabled during tracking modes to enable the amplifier to linearly amplify the voltage developed across the capacitor and is enabled during the sampling mode to differentiate the voltage that occurred immediately before the switch is turned off for application to the input of the amplifier for linearly interpolating the noise-affected portion of the signal.

Abstract: The present invention relates to an orthodontic appliance to treat irregularities of teeth by attaching an arch wire holder to a plurality of teeth and then connecting one or more orthodontic wires to the arch wire holders. The bracket constituting an arch wire holder is provided with an arch wire fixing slot formed with a specified radius of curvature approximately conforming to the diameter of the arch wire. The curvature radius of the arch wire fixing slot is determined by the purpose of application, namely, it depends on whether it attaches onto the outside (buccal side) surface or the inside (lingual side) surface of the teeth, and for which teeth it is employed. This arch wire holder is especially effective when the bracket is attached to the inside of the teeth for orthodontic purposes, for it then allows the application of corrective forces on the teeth without being easily visible in the user's mouth.

Abstract: An exhaust passage extends from an internal combustion engine to conduct exhaust from the engine. A filter is disposed in the exhaust passage to filter particles out of the exhaust. A burner is disposed in the exhaust passage upstream of the filter to burn off the particles retained by the filter. A sensor senses the pressure across the filter and generates a signal indicative thereof. Another sensor senses an operating condition of the engine. A first device generates a primary reference signal on the basis of the sensed engine operating condition. A second device samples the pressure signal when the pressure sensor is subject to a zero pressure difference. A third device stores the sampled pressure signal. A fourth device corrects the primary reference signal on the basis of the stored pressure signal and generates a secondary reference signal reflecting the correction.

Abstract: Disclosed is a semiconductor memory device which is one of three types of semiconductor memory devices, one operable only in page mode, one operable only in nibble and one operable selectively in page mode or nibble mode, being obtained from a partially unconnected semiconductor memory device through alternations in a portions in wiring. The semiconductor memory device includes first and second internal column address strobe signal generator. The second internal column address strobe signal generator has at the first stage thereof a NAND circuit one of inputs to which determines the type of the semiconductor memory device depending on which of three kinds of signals is selected as the input. Selection of such an input is effected by an aluminum wiring process using a mask. Such selection of the input causes variation in the input response characteristics of the output of the second internal column address strobe signal generator, thus providing a desired response appropriate for the selected mode or modes.

Abstract: A flexible heating wire includes a first conductive body, a second conductive body, a thermally fusible electrically insulative body which are arranged such that the first and second conductive bodies will be brought into electric contact with each other when the thermally fusible electrically insulative body is thermally fused, a third conductive body, and a heating body having a positive temperature coefficient and held in electric contact with at least one of the first and second conductive bodies and the third conductive body. The flexible heating wire is capable of self-controlling the temperature of the heated heating body. The flexible heating wire can detect the danger of localized overheating, abnormal overheating, or the generation of an arc which is caused when the heating wire is subjected to external oppression, bending, or twisting, or when the heating wire is heated by an external source, or when a conductive material has been mixed in the PTC heating body.

Abstract: In manufacturing a DC motor body (1) including a motor magnet (2), conventionally, a magnetized magnet (2) is fitted to one by one to the cylindrical molding core (11) and a motor body is injection-molded within a cavity formed between a motor body forming mold (10) and a cylindrical molding core (11) to which the magnet is attached. Therefore, the magnet should previously be molded and stocked before molding the motor body, thus not being applicable to mass-production processes. To overcome the above problems, the motor magnet (2) and the motor body (1) are molded in sequence in accordance with two separate molding steps by the use of the same molding core. This method can eliminate troublesome magnetic fitting work, the need of magnet stock and enhance the dimensional precision of motor magnet, thus being applicable to mass-production process while increasing the energy transduction efficiency of the DC motor.

Abstract: In a noise reduction circuit for reception of stereophonic FM signals in which the demodulated signal is chopped at twice the pilot frequency for separation between left- and right-channel signals, the demodulated signal is sampled by a first sample-and-hold circuit in response to the output of the noise detector to store that portion of the signal which appeared immediately prior to the occurrence of an impulse noise. The demodulated signal is also sampled by a second sample-and-hold circuit at a frequency twice the pilot frequency to eliminate a noise which might arise due to the chopping of the demodulated signal. A signal is derived from the outputs of the first and second sample-and-hold circuits that indicates the slope ratio of the demodulated signal at the moment that occurred immediately prior to the impulse noise.

Abstract: The invention relates to a digital multiplex device for branching a digital information stream. In relatively small individual telephone networks using digital transmission techniques and comprising a few intermediate stations and terminal stations, a need has arisen to branch groups having less than 30 channels. To branch such groups in a digital manner, i.e., without first decoding the signals to voice-frequency signals, a phase compensating device includes four switches, four time multiplexers, and two frame phasers and two control units for controlling the switches and time multiplexers. The device comprises two identical units, and is suitable for branching other digital information, besides data signals having a standard frame structure. Moreover, the transmission rate of the branched line may differ from that of the main line by using a rate modifier.

Abstract: A lamination of a resilient and elongate magnetic sheet and a conductor strip is rolled up around a magnetic winding core to form a roll, and then the roll is sintered to produce an intermediate product. The conductor strip has both ends at both sides of the magnetic sheet so that both ends of the conductor strip are respectively exposed at both sides of the roll. Terminal electrodes are respectively attached to the both sides of the intermediate product to complete the chip coil. Another magnetic sheet may be provided to make the thickness of the lamination substantially uniform throughout the entire area. A second conductor strip may be provided in the lamination so that a coil having a tap can be actualized. The shrinkages of the winding core and the magnetic sheet are selected so that a desirable sintered product will result without suffering from delamination or cracks.

Abstract: A variable electrical energy stabilizer is supplied with a source having a voltage magnitude that varies to maintain a constant ratio with the pulsation frequency of the source. The variable supply is derived from a variable energy source such as a kinetic energy accumulator which is intended for feeding a telephone exchange or an electrical unit on a sealed off site. The stabilizer supplies a d.c. output current to a load having a predetermined impedance. To provide the load with continuous energy with a constant amplitude via solely passive components, the stabilizer comprises an inductive circuit having an inductance substantially equal to the quotient of the constant ratio to the amplitude of the output current. The inductance circuit has a very high impedance compared to the load impedance.

Abstract: Values of color component densities for Red(R), Green(G) and Blue(B), the primary colors of a light image, are used to provide data for each of a number of printing inks, such as Cyan(C), Magenta(M), Yellow(Y) and Black(B.sub.K), used for producing multi-color prints. The data, obtained by applying the so-called "density-saturation theory", are retrieved from a memory device and added selectively for all the ink colors to obtain total density signals representative of the color components. After processing, these signals control a color cathode ray tube (CRT) to display a color image simulating the multi-color prints.
