Title: Measurement of luminous intensity balance
Inventor: MITSUMOTO ICHIROU
IPC: G01B11/00
Filed: 1980-04-12
Abstract: PURPOSE:To make effective use of the quantity of received light and improve the accuracy of measurement by using the light receiving surface consisting of photocells divided respectively to equal areas in longitudinal and transverse directions. CONSTITUTION:The rays falling to the light receiving surfaces of the respective photocells 3a, 3b, 3c, 3d of a photodetecting body are converted to the electric outputs A, B, C, D corresponding to the quantities of the light. These electric outputs are added to A+B by an adder 13, to A+C by an adder 14, to C+D by an adder 15, and B+D by an adder 16, respectively. Next, these are subtracted to (A+B)-(C+D) by a subtractor 17 and to (A+C)-(B+D) by a subtractor 18, respectively. These results are indicated by a vertical balance meter 8a and a lateral balance meter 8b, respectively. Since the entire quantity of the light falling onto the light receiving surfaces is used in either of the comparison of the vetical quantities of light and the comparison of the lateral quantities of light in this way, the accurate luminous intensity balance is measured. Hence, the accuracy of measurement is improved.

IPC: G01S15/08
Filed: 1988-02-29
Abstract: PURPOSE:To remove the influence of residual vibration by increasing a gain with time when an ultrasonic wave for vehicle interval distance measurement is modulated and demodulated and transmitted in two ways between a master equipment and a slave equipment. CONSTITUTION:The ultrasonic wave which consists of a pulse train is outputted from an ultrasonic vibrator 6 through a transmitting circuit 4 according to the output of the modulating circuit 3 of the master equipment 1.

IPC: B29L30/00
Filed: 1984-03-15
Abstract: PURPOSE:To contrive to achieve two color molding automatically by raising and lowering the core member fitted into the bottom force of a mold by a cam mechanism. CONSTITUTION:A bottom force is retracted, while carrying a primary product and rotating by 180 deg., and then is moved to the mold for secondary molding and is fitted to a top force. When the top force 4 is closed, a plate 5' is lowered, thereby pushing the tapering part of a cam plate 6' and moving it left. Consequently, the cam plate 6' is caused to be in contact with the projected part of a follower plate 7, and the follower plate and a core member 2' are pushed up, whereby a cavity is formed in between a projected portion 9 and the bottom force 1. Secondary molding material is injected into this cavity for secondary molding, and the product in which resin enters under side of the projected portion, is obtained. Next, the bottom force 1 is retracted, and it is turned by 180 deg. after a product has been pushed out, and then the top force is closed. Then, the side plate 5 pushes the cam plate 6 left, and the cam plate 6 is caused to be in contact with the recessed part of the follower plate 7, thereby lowering the follower plate 7 and the core member 2. The molding is achieved, repeating these operations automatically. The molded product which has been impossible to be molded by one time up to now, may be automatically produced by such simple operation raising and lowering the core member.

Title: Optical switch
Inventor: IIDA TAKESHI
IPC: G02B26/08
Filed: 1988-03-01
Abstract: PURPOSE:To eliminate variation in the power of output light at the time of switching and to facilitate adjusting operation by forming a plane and switching optical paths by the swinging of a mirror which swings in the plane. CONSTITUTION:The plane is formed and the optical paths are switched by the mirror 46 which swings in the plane. Even if chattering occurs on the mirror 46 at the time of the swinging operation, the optical path is not changed and light is accurately incident on optical fibers 12 and 14. Further, the optical paths are switched by the plane mirror 46, so even if the mirror 46 has an error in size, etc., optical fibers 11-14 need not be shifted in position. Further, the mirror 46 is swung by rotary motion around an axis perpendicular to the mirror 46, so the influence of the direction of gravitation upon the swinging speed is small. Consequently, the power of the output power does not vary at the time of the switching and the adjusting operation is facilitated.
