Title: Power steering device
Inventor: CHIKUMA ISAMU
IPC: B62D6/00
Filed: 1985-07-05
Abstract: PURPOSE:To enable the high torsional rigidity to be selected of an elastic body by providing a rotational displacement positively to an input shaft of a rotational displacement generating section in a steering angle ratio changing mechanism by making use of the reaction of a steering angle reaction generating mechanism. CONSTITUTION:The reaction hydraulic pressure is scarcely exerted in the range of a low speed, and only a torque which is a product of a cut-off angle of a rotary spool 9c of a rotary selector valve 9 and a spring constant of a torsion bar 23, is required as a steering torque. And in the range of a high speed, the sufficient reaction hydraulic pressure is raised even if the steering torque is small, and the rotary spool 9c of the rotary selector valve 9 is little rotated. Accordingly, in the steering angle ratio changing mechanism, a torsional angle of the torsion bar in the range of the high speed is several times as large as that in the range of the low speed. Furthermore, in view of the relation between the steering torque and the steering angle, the steering angle ratio in the range of the high speed is larger by far than that in the range of the low speed.

IPC: H01S5/00
Filed: 1987-06-12
Abstract: PURPOSE:To enhance the ratio of refracted and guided light to a light and to reduce an astigmatism by substantially bringing the width of a current injection unit in coincidence with the effective width of the current injection to an active layer, and increasing the width of the first conductivity type of the current injection region larger than that of a photoconductive wave groove. CONSTITUTION:A current limiting layer 10 near a photoconductive wave groove 1 is formed in a first conductivity type semiconductor (N-type GaAs) to form the semiconductor region as a current injection region 11. Since the width of the region 22 is substantially brought into coincidence with the effective width of the current injection to an active layer 4, the width of the first conductivity type which becomes the region 11 may be formed to be larger than the width of a photoconductive wave groove 1. Thus, the ratio of refracted and guided light is enhanced, an astigmatism is reduced, and the variation amount of the astigmatism upon alternation of a light output is decreased.

IPC: H05K7/20
Filed: 1982-08-26
Abstract: PURPOSE:To efficiently cool packages of large heat value by a method wherein a ventilation guide plate whose gap between the package is wider in the lower part and narrower in the upper part is provided by the side of the packages of large heat value. CONSTITUTION:Forced ventilation is performed from under a cabinet which vertically supports a plurality of electronic circuit packages 3 and 4. At the time, the ventilation guide plate 6 whose gap between the package 4 is wider in the lower part and narrower in the upper part is provided by the side of the package 4 of large heat value. Since the wind fed from under is concentrated to the package 4 of large heat value by the ventilation guide plate 6, the effect of cooling the package of large heat value can be enhanced without increasing the total amount of ventilation.

Title: Mold for reactive injection molding

IPC: B29C33/10
Filed: 1982-08-26
Abstract: PURPOSE:To prevent the occurrence of voids in the inside of a wire body by a method in which a degassing hole is provided to a cavity to form a synthetic resin wire body in molds having small wire or thin face at the inside end connected to a framework with large four circumferences. CONSTITUTION:A metal chip 8 having a large number of fine holes leading to cavities 6a and 6b is provided to a top force 7. From the fine holes, gas, e.g., air, etc., is discharged to the outside of molds. The fine holes are so fine that reactive mixtures are hard to flow into the holes but are pervious to air, etc., through which degassing could be attained by suction as needed. Although the position of the degassing hole is usually deviated to the central part in the longitudinal direction of a wire, the greater the difference between the cross section of the framework 1 and the cross section of the wire 2 becomes, the position of the degassing hole is not varied only by the difference in the cross sections but varied by shapes of the cavities. The remaining of air voids can thus be prevented.

Title: Data imprinting circuit
Inventor: IGAWA KAZUO
IPC: G03B17/24
Filed: 1986-06-24
Abstract: PURPOSE:To uniform the exposure of data regardless whether a camera is in horizontal or vertical position photography by providing plural light sources for the data imprinting of the camera, and turning on the light source for the data imprinting selectively with a position sensor switch. CONSTITUTION:When the camera body is put in photography at a horizontal position, a position detection switch PSS is turned on to supply a base current to a transistor TR 4, which conducts for a specific time. Consequently, a TR 2 turns on, so a lamp LH illuminates for a specific time and light from the lamp LH is transmitted through the transparent data part of a liquid crystal device, thereby exposing the surface of a film F to data. Then when the camera is put in photography at a vertical position, the switch PSS is turned off, so the TR 4 turns on and a current flows through base resistances 5 and 11 of a TR 10 to turn on a TR 6 simultaneously with the TR 10, so that a lamp LV illuminates for a certain time. The TR 10 is put in operated in its saturated state, so the brightness of the lamp LV is nearly equal to that of the lamp LH and the exposure of the data to the surface of the film F is equal regardless of a photograph is taken at the horizontal or vertical position.
