Title: Printed board feeding device
Inventor: WADA SHOICHI
IPC: B65H3/30
Filed: 1985-07-30
Abstract: PURPOSE:To reliably feed printed board, in order from the printed board in a lowermost position, by a method wherein a pair of holding means, by means of which the lowermost printed board but one is releasably held and is dropped to a lowermost position, is situated right above a pair of locking means by means of which the lowermost printed board is engaged and disengaged. CONSTITUTION:First, locking plates 6 are caused to enter in a direction different from each other, a holding plate 7 is moved backward, and printed board 1 are piled up in quantities on the locking plates 6 between width determining plates 5. Secondly, the holding plates 7 are caused to enter in a direction different from each other in a condition that the locking plates 6 are left entering, and the side end surfaces of a lowermost printed board but one 1d are pressed between the nip formed by the holding plates 7. With this state, the locking plates 6 are moved backward in a direction different from each other, and only a printed board 1c in a lowermost position is dropped for feed onto conveyance rails 8. Thereafter, the locking plates 6 are caused to enter again, the holding plates 7 are moved backward, the printed board 1d is dropped to a lowermost position and is locked to the locking plates 6.

Title: Cleaning device
Inventor: MIYAZAWA YOSHINORI
IPC: G03G21/10
Filed: 1986-07-18
Abstract: PURPOSE:To improve the storing efficiency of a cleaning device by abutting a blade upon an image carrier on a position restricted within a specific angle on the downstream side from the lower part of the vertical axis of the image carrier and arranging a waste toner container on the lower part of the image carrier. CONSTITUTION:The blade 16 is abutted upon the image carrier 1 on the position restricted within 15 deg. on the downstream side of the image carrier rotating direction from the lower part of the vertical axis of the image carrier 1. Thereby, removed toner is naturally dropped into the waste toner container 6. Since the blade 16 is raised at an angle approximate to 90 deg., toner is not stuck on the blade 16. On the other hand, the abutting angle of the blade is about 70 deg. from the tangential direction of the image carrier. So far as the abutting point exists on the downstream side of the lowermost point of the vertical axis of the image carrier, the toner is not stuck on the blade. Said constitution make it possible to improve the toner storing efficiency of the cleaning device.

Title: Optical memory device
Inventor: OOTA KENJI
IPC: G11B7/24
Filed: 1982-09-27
Abstract: PURPOSE:To increase the signal quantity of guide information, by coating light- transmissive materials different in refractive index on a transparent substrate to form a groove and forming a transparent film different in refractive index on them. CONSTITUTION:Grooves 2' of interrupted lines are formed on a transparent plane substrate 1 consisting of a glass plate by a photoresist film (n=1.65) 2 to constitute a light-transmissive substrate 3. A transparent SiO film (n=1.95) 4, a vertical magnetized film 5 to be a recording medium, a transparent SiO2 film 6, and a Cu film 7 are formed on this substrate 3. The reduction of an incident laser light from the side of the substrate 1 in a position B (groove 2') where the photoresist film 2 does not exist is detected as a guide signal. The thickness of the SiO film 4 different in refractive index from the photoresist film 2 is selected properly to increase the quantity of a guide signal because of the diffraction effect and the light reduction effect based on the difference of reflection factor.

Title: Method and device for evaluation of logical gate
Inventor: SUGANO MASAHIDE
IPC: G06F17/50
Filed: 1988-07-07
Abstract: PURPOSE:To obtain the output state of a logical gate at high speed by using at least an arithmetic unit containing a logical computing element and a comparator and an encoder which receives the output of said comparator and produces the output state data on the logical gate. CONSTITUTION:A logical computing element 10a performs the logical arithmetic between a state data 12 on an input terminal and the 1st mask data 16 and defines a specific state of the input terminal. Then the result of the logical arithmetic is compared with the 2nd mask data 15 via a comparator 10b so that the specific state of the input terminal is detected. One or plural pieces of arithmetic unit 10 consisting of the element 10a and the comparator 10b are prepared as necessary. Thus the state of the input terminal necessary for evaluation of a logical gate can be known. As a result, the output state 14 of the logical gate is obtained by encoding the output of the comparator 10b of the unit 10 via an encoder 13. Then the output state of the logical gate is obtained in a simple constitution and at high speed.

Abstract: PURPOSE:To realize a low frequency pulse train detection circuit able to detect a low frequency pulse train by providing a monostable multivibrator circuit, a counter circuit and a counter control circuit to the circuit. CONSTITUTION:So long as a faulty detection pulse train outputted from a counter or the like being an object of fault detection is continuously inputted, the count of a counter 4 is continued to retrigger a monostable multivibrator circuit 2 with a frequency division output continued to be outputted from the counter 4 and the monostable multivibrator circuit 2 outputs a display representing the normality of a counter or the like being an object of fault detection.

IPC: G06F9/46
Filed: 1987-07-07
Abstract: PURPOSE:To reduce the hardware scale, by deciding the malfunction to generate an alarm signal by a processing circuit when the count value of a counter reaches a prescribed value. CONSTITUTION:Two programs monitor the malfunction by each other in a processing circuit 1. If it is detected that one program which should be already executed is not executed when the other program is executed, the detection output is periodically given to a counter 2, and the counter 2 counts this detection output. When the count value reaches the prescribed value, that is, when a certain timer time elapses, the malfunction is decided by the processing circuit 1 to generate the alarm signal. Two programs monitor each other to execute the processing in this manner. Thus, the malfunction of programs is monitored with a small hardware scale.
