Patent JP-S5478688-A (JP)
Title: Ultrasonic converting method
Inventor: TODA KOUJI
IPC: H04R17/00
Filed: 1977-12-06
Abstract: PURPOSE:To make it possible to focus beams on one point by an ultrasonic oscillator with blind-shaped electrodes by making electrode intervals and the phase difference of an applied signal satisfy the fixed conditions. CONSTITUTION:On the surface of a piezoelectric substance, blind-shaped electrodes 4a to 4i are arranged in the longish direction of electrode fingers, and every n-th electrode is connected in common, so that a n-phase electrode can be constituted. Now, setting electrode intervals under fixed conditions enables ultrasonic beams to focus in one direction (X-axial direction). On the other hand, when electrodes 4a to 4i are applied with signals which are equal in fequency and out of phase satisfying the fixed conditions, ultrasonic beams focus in the Y-axial direction. They therefore focus on point F through combinational focusing in both X-axial and Y- axial directions. In addition, a plural number of different electrode groups are provided onto the surface of a single piezoelectric substance and applied signals are changed over to make it possible to obtain an ultra sonic wave which is able to vary its focal length. On the contrary, it is possible to detect an ultrasonic wave and convert it into electric energy.

Abstract: PURPOSE:To prevent the damage of a photosensitive drum and the entry of dust into a photosensitive drum part when a developing device is replaced, by closing the shutter of a main-body side when the developing device is detached from the main body and protecting the photosensitive drum. CONSTITUTION:While the developing device 5 is set to the photosensitive drum 2, the shutter 21 which moves up and down at the opening 29' of the wall 29 of a copying machine body is left open while supported on a shaft 28 provided to the developing device 5. At this time, a cam 26 falls down to press the developing device 5 toward the photosensitive drum 2. The lever 27 of the cam 26 is rotated as shown by an arrow b1 to release the developing device 5 as shown by an arrow b2. At this time, the shaft 28 moves up slightly by theoscillation of the developing device 5 on rails 30' and 30'' to elevate the shutter 21. The released developing device 5 is drawn out to this side along the rail 30' provided to the main frame side and the shutter 21 is closed automatically by its own weight after the developing device 5 is drawn out completely.

Title: Switch-back controller for unmanned vehicle
Inventor: KITAJIMA JIYUNJI
IPC: B60L15/20
Filed: 1981-09-17
Abstract: PURPOSE:To simplify the structure of a switch-back controller for an unmanned vehicle by generating a stop signal according to a switch-back signal outputted from the prescribed position of a rail and switching forward or reverse signal, thereby releasing the stop signal when the vehicle is stopped. CONSTITUTION:When a power source is energized, flip-flops 4, 7, 9 are all reset, and a forward signal is outputted from a forward signal output terminal 8. When an operatorless hegicle reaches the prescribed ground point, the output of a switch-back signal detdctor 12 becomes ''H'', and the flip-flop 7 is set. As a result, a stop signal is outputted from a stop signal output terminal 15. When the vehicle completely stops, the output of a stop detector 1 becomes ''H'', the flip-flop 4 is set, and a reverse signal is outputted from a reverse signal output terminal 5. Since the flip-flop 7 is reset at this time, the stop signal is released.
