Abstract: PURPOSE:To utilize effectively a light beam and to reduce the cost of a device by using one light beam for guiding a moving body and for information transmission. CONSTITUTION:The laser beam LB1 emitted by a laser beam generator 11 is passed through a slitter 12 and reflected by a rotary mirror 13 to the moving body. This beam LB1 is reflected by the corner cube 33 of the moving body in the same direction and branched by the slitter 12 to enter a photodetector 16. A tracking direction discrimination circuit 17 and a tracking signal circuit 18 supply a tracking signal to a microcomputer 19 with the output of the photodetector 16, and pulse motors 14 (14a and 14b) are controlled to irradiate by moving body with the beam LB1 all the time. If the moving body deviates from a course, the rotary mirror 13 varies in angle of rotation, which is detected by rotary encoders 15 (15a and 15b), whose outputs are inputted to the microcomputer 19 to modulate the beam LB1 and irradiate the moving body. The moving body passes the beam through a demodulator 36 and a signal processing circuit 37, and a microcomputer 39 corrects the course of the moving body by a steering device 38.

Inventor: KIMURA SHINTARO
IPC: G01S7/52
Filed: 1984-07-26
Abstract: PURPOSE:To detect even a short-range object while checking it by a primary reflected wave, by absorbing attenuated vibration energy accumulated in an ultrasonic vibrator during the transmission depending on a conjugate impedance with the end of the transmission. CONSTITUTION:An ultrasonic wave is transmitted on a signal from a synchronous signal generation circuit 5 and with the end of the transmission, first and second control signals are inputted into a switching circuit 10 and an amplifier 7 to absorb and consume attenuated vibration energy of an ultrasonic vibrator 2 depending on a conjugate impedance 9. At the same time, the gain of the amplifier 7 lowers to reduce the reverberation time before the reverberation wave at the vibrator 2 vanishes. This allows even short-range object to receive the primary reflected wave satisfactorily without being affected by attenuated vibration of the ultrasonic vibrator thereby assuring an accurate detection even a short- range object.

Title: Cooker
Inventor: TANAKA MASAAKI
IPC: F24C7/02
Filed: 1989-06-20
Abstract: PURPOSE:To prevent breakage of a transmission body by a method wherein a second coupling part forms an arcuate surface so that it can be inserted through an opening without being blocked by the peripheral edge of the opening when the transmission body is rotated centering around one peripheral edge of a first coupling part. CONSTITUTION:When a transmission body 29 is rotated around one peripheral edge 30a of a first coupling part 30, since a second coupling part 31 has an arcuate surface 32, it is smoothly inserted through an opening 28 without making contact with one peripheral edge 28a of the opening. A drive shaft 26 is then coupled to the second coupling part 31. In this case, even when the transmission body 29 is lifted upward, a block body 33 makes contact with other peripheral edge 28b of the opening 28, and the second coupling part 31 can not be pulled off from the opening 28. This constitution transmits a drive force to a turn table 25 through the transmission body 29, and makes the transmission body 29 difficult to break.
