Abstract: A resistor element has a ceramic body with a first outer electrode and a second outer electrode formed on its mutually opposite externally facing end surfaces and a plurality of mutually oppositely facing pairs of inner electrodes inside the ceramic body. Each of these pairs has a first inner electrode extending horizontally from the first outer electrode and a second inner electrode extending horizontally from the second outer electrode towards the first outer electrode and having a front end opposite and separated from the first inner electrode by a gap of a specified width, these plurality of pairs forming layers in a vertical direction. The gap of at least one of these plurality of pairs of inner electrodes is horizontally displaced from but overlapping with the gaps between the other pairs of inner electrodes. For producing such a resistor element, the distance of displacement is set according to a given target resistance value intended to be had by the resistor element.

Abstract: A fixture for use in assembling a first element and a second element is provided. The first element is substantially in shaft type and the second element includes a sleeve defining an axial channel. The first element is received within the axial channel in a non-engagement condition before assembly. The assembly fixture includes a lower mold device and an upper mold device. The lower mold device is used to place the first element and the second element in a non-engagement condition before assembly. The upper mold device includes a rotatable concentricity alignment device. As the upper mode device and lower mold device are operated under a mold-press condition, the concentricity alignment device automatically performs concentricity alignment procedure of first element with regard to the sleeve of the second element and accomplishes the press fit process.

The control computer of each user has a diagnostic data memory for storing diagnostic data which are used for diagnosing troubles occurring in the device and is capable of setting the diagnostic data in a form of electronic mail receivable by the relay stations. The maker's trouble-diagnosing computer is capable of reading out and saving electronic mail messages from the user's control computers stored at an associated one of the relay stations.

Abstract: A tubular insert with a small internal volume is disposed inside the vaporization chamber at the inlet of a capillary column of a gas chromatograph such that the sample with a solvent injected into the vaporization chamber is carried by a carrier gas through the insert into the column. The internal volume of the insert is such that the retention time of the carrier gas through the insert is less than 4 seconds. A heater is controlled to maintain the temperature inside the vaporization chamber within a specified range above the boiling point of the solvent as the sample is injected into the vaporization chamber, and this temperature is subsequently raised to a final temperature above the boiling points of the components to be analyzed. The carrier gas pressure is temporarily increased for better efficiency as the sample is injected.

Abstract: A multi-piece waste and overflow unit is used with a bathtub to remove waste water via the overflow drain hole, bottom drain hole, or both holes of the bathtub. The multi-piece waste and overflow unit includes a bottom connector and overflow connector. Both connectors comprise a tubular member, a flange extending radially outwardly with respect to the tubular member, and a frustoconical connector between and connecting the tubular member and the flange. The flanges have a channel formed thereon to receive leakproof adhesive for connecting the connectors to the bathtub respectively. The multi-piece waste and overflow unit also utilizes elbows, T-joints, and conventional pipes for connecting the bottom and overflow connectors.

Abstract: A method of cutting hair is provided. First, a strip of adhesive tape is attached onto a person's hair. Second, the hair below an edge of the strip of adhesive tape is removed by cutting along the edge. And third, the strip tape is detached. The present inventive method of cutting hair may be used to remove hair that is either dry or damp.

Abstract: A ballast circuit adaptive to changes in the input voltages capable of providing a "floating" high output voltage for the operation of fluorescent lamps. The present invention employs an output voltage "floating" design in adjusting the voltage gain of the ballast circuit in response to the voltage difference between the output voltage and the rectified input voltage (i.e. error voltage).

Abstract: A substrate to be coated with a thin film is placed inside a vacuum chamber, an ECR plasma is generated and introduced into the vacuum chamber by means of a specified magnetic field generated inside the vacuum chamber and a reaction gas, as well as an inert gas, is introduced into the vacuum chamber while a negative DC voltage superposed with a high-frequency pulse with frequency 25-250 kHz is applied to the substrate by a voltage applying device such that the voltage of the substrate reaches a positive value instantaneously. The frequency of the superposed pulse is selected by using an ammeter to determine an optimum frequency for minimizing the load current of the voltage-applying circuit.

Abstract: A camera for underwater photography may be used together with one or more flash lamps each capable of serving both as a main lamp and as a slave. The camera is connected through its housing to a main lamp by way of an optical cable and when it is clicked, a control signal is emitted as a light signal and transmitted to the main lamp through the optical cable. The flash lamp has a photosensing unit for receiving a light signal and converting it into an electrical signal. A signal conversion circuit further converts this signal into a flash control signal by which the lamp flashes light. The photosensing unit is connected to the optical cable through a connector and receives light only through the cable when the connector is attached to it. When the lamp is used as a slave, the connector for the optical cable is detached from the photosensing unit and external light received through a transparent window is converted into an electrical signal for the emission of flash light.

The switch element, responsive to the reciprocal movement of the keycap, selectively turns ON. The rubber sheet is disposed on the switch element. The housing includes a pair of hook devices. The hook device and the housing constitutes a slot. A opening is provided on the housing at location corresponding to the hook device. The balance lever includes a longitudinal portion connected to two traverse portions forming an "U" shape. The end of the traverse portion is disposed into the slot corresponding to the hook device. A protrusion is provided integrally on the rubber sheet at location corresponding to the hook device. The protrusion passed the opening and contacts with the end terminals of the traverse portions of the balance lever to lower the noise.

Mutually corresponding ones of these output transistors of different ones of the converter units, which are switched on and off together, are disposed adjacently and connected together to a trunk power supply line such that the parasitic resistances through the conductive lines connected to the output transistors are alike and the conversion characteristics of the individual converter units also become alike. One common input transistor may be shared by all of the converter units for further improving the conversion characteristic.
