Abstract: When heating a semiconductor wafer by means of application of radiated light, subsidiary heating means which elongates along the circumference of the wafer is employed to additionally heat or to preheat the circumferential portion of the wafer so as to make the temperature of the wafer uniform at the entire surface thereof. Use of such subsidiary heating means is effective to prevent the occurrence of such a damage as slip line or the like in the wafer.

Abstract: A stabilizer used for vehicles and the like is formed integral with a base, shoulders on both sides of the base, and arms each formed with an eye-termination provided at the free end thereof for connecting the stabilizer to a load, said arms being each partly provided in separation from the remaining part of the stabilizer and welded to the latter at a predetermined position thereof the weld position satisfying a condition for maintaining sufficient strength of the stabilizer, to thereby produce the stabilizer more easily with a reduction in cost as well as to heighten the spring property thereof.

Abstract: Dopant atoms are diffused into a silicon wafer by heating the entirety of the silicon wafer with the dopant atoms to a predetermined diffusing temperature in a short period of time, and more specifically, by applying light onto the silicon wafer under such conditions that the temperature difference between a central part of the silicon wafer and its peripheral part is maintained within 65.degree. C. The above diffusion method permits to carry out diffusion of the dopant atoms into silicon wafers with high productivity but without inducing physical defects such as warping or slip lines. It requires a very short time period for effecting diffusion to a desired extent and it enables to make the depth of diffusion greater.

Abstract: When heating a semiconductor wafer by means of application of radiated light, it is effective to employ subsidiary heating means whose temperature rises upon exposure to the radiated light so that the circumferential portion of the wafer is additionally heated to compensate radiation of heat therefrom. The subsidiary heating means is arranged to elongate along the circumference of the wafer. It is important to limit the ratio of the characteristics, whose definition will be given below, of the subsidiary heating means to that of the wafer to 0.6-1.4 in order to avoid the occurrence of such a damage as slip line or the like in the wafer. The characteristics are expressed by the following formula: ##EQU1## wherein .eta.: reflectivity;.rho.: specific gravity (g/cm.sup.3);d: thickness (cm); andC: specific heat (joule/g.multidot..degree.C.).

Abstract: A distortion-free amplifier in accordance with the present invention includes an input amplifier, an output amplifier and method, and a cooperative combination of negative and positive feedback loops that remove substantially all distortion and error in the amplified output. Negative feedback loops are provided around the output amplifier and the input/output amplifier combination to provide degenerative error reduction. The negative feedback loop around the output stage provides a portion of the output to a voltage node at which the error component of the output signal is inversely superposed on the inverted signal to be amplified. This highly "visible" (inverse, intra-loop) error component is utilized as positive feedback to provide a regeneratively enhanced error pre-correction of the signal in the input amplifier. The pre-correction can be precisely controlled to effect virtually complete serial cancellation of the to-be-introduced error as the signal is propagated through the amplifier.

Abstract: A nutating traction drive in which external rolling surfaces on a one-piece biconical body (10) are retained against axially spaced internal ring surfaces (51,52) at diametrically opposite points of contact by a mechanism acting between a body (18) which is rotatable on the axis of the ring surfaces or a first axis (24) and which carries the biconical body (10) on a second axis (30) inclined with respect to and intersecting the first axis at a point (S) of axes intersection located midway between the ring surfaces (51,52) and points of contact. The mechanism includes a pivotal member (66) having a fulcrum point (78) eccentric from the first axis (24) or displaced from a plane containing both the first (24) and second (30) axes so that a torque reaction to rotation of the carrying body (18) by the biconical body (10) results in a force attempting to increase the angle between the first (24) and second (30) axes.

Abstract: A rain shield accessory for jacketed insulated pipe installations having vertically projecting rod-like appendages such as hanger rods, valve stems, and the like. The rain shield is an inverted funnel-shaped member of resilient sheet material so as to define a frustoconical body portion joined at its upper or small diameter end with a coaxial cylindrical neck portion. The sheet material from which the member is formed is precurled about the axis of the body to provide a voluted overlap particularly in the region of the cylindrical neck portion so that the member can be opened and placed about rod-like appendages of widely varying diameters.

Abstract: A pallet container system having strap-like clamping devices to retain five or more rectangular panels in either an erect box-like condition or in a collapsed condition in which the panels are compactly stacked for handling and storage during non-use. The panels are provided with recess formations spaced from each peripheral edge by a common marginal distance related to the combined thickness of five panels. The clamps are preferably L-shaped in configuration to define legs differing in length from each other by the thickness of one panel. In the erect condition, the short leg extends about the edge of one panel and along the surface of another panel oriented at right angles to the one panel so that clamping projections at the ends of the legs engage in the recessed formations. In a collapsed condition, the panels are stacked and the clamp engaged about the edges to retain the panels in an overlying stacked relationship and also to retain a complete set of clamps with the stacked panels.

Abstract: A holder holding capacitor elements is transported by a conveyor and brought into an electrolyte impregnating tank, which is then closed up by a cover which is secured to a carrier movable laterally by a linkage and is moved vertically by a swingable link. A vacuum pump is operated to vacuumize the electrolyte impregnating tank, and then an electrolyte to supplying circuit is operated to supply the electrolyte into the tank of a predetermined vacuum, so that the capacitor elements may be impregnated with the electrolyte by the minus pressure of vacuum. An absorbing device with a pump is operated to absorb the extra electrolyte around the capacitor elements which are placed in the device.

Abstract: A structural support system for a wind driven power plant includes a plurality of circular support frames that are supported relative to a stationary foundation by support columns. The support frames are mounted coincident with and spaced along a support-system longitudinal axis with each frame having a circular inner and a circular outer support ring. Axially directed stringers are connected to and extend between respective inner and outer support rings with associated stiffners to provide a structurally enhanced framework for supporting wind driven power plants. The support columns are preferably hinged to the foundation to permit the columns to be fabricated at ground level and pivoted into an upright position for connection to the associated support frames to provide the completed structure.

Abstract: The invention discloses an auxiliary head lamp device for a car equipped with a cover which is optionally fitted to a car and is lit during driving in fog or the like. The cover of this device can be opened when a solenoid of a cover driving mechanism is energized by operating a switch disposed inside the room of the car. The solenoid releases engagement of a stopper that restricts the cover urged in the opening direction. The switch may be used also as a switch for a light source bulb. After the solenoid is energized and the opening operation of the cover starts, a current to the solenoid is automatically cut off so that over-heat or burn-out of the solenoid that would occur if the current is continuously applied thereto can be prevented.
