IPC: B65H3/44
Filed: 1986-04-24
Abstract: PURPOSE:To simplify and miniaturize the structure of a sheet feeding device, by providing a drawing device which guides a desired sheet feed table to a position below a sheet feed means. CONSTITUTION:After a sheet feed table C2 is positioned to the inlet of a sheet feed part, a motor for a drawing device is run to draw a sheet feed table C2 to a drawing position. With an elevating device actuated, an uppermost sheet on the sheet feed table C2 pushes upward a roller 55 of a sheet feed means and a shaft 54 thereof, and a holding member is raised until a photo interrupter 57 is caused to perform a motion of shielding light. And when the sheet feed table C2 is positioned in the working position of a suction cylinder 52, the elevating device is rendered inoperative. A valve member 67 is released, and a sheet feed roller 64 is rotated to perform desired feed of a sheet. When the sheets on the sheet feed table are decreased along with the feed of sheets and the shaft 54 is moved aside from the light shield passage of the photo interrupter device 57, the elevating device is actuated again to raise the sheet feed table, and the level of an uppermost sheet is maintained in the working position of the suction cylinder.

Title: Copying system for set value to nonvolatile memory
Inventor: FUJII KATSUYASU
IPC: G11C17/00
Filed: 1987-04-17
Abstract: PURPOSE:To improve the reliability of the titled system by carrying out automatically a copying action after deciding this action by comparing the values recorded on a specific address with each other. CONSTITUTION:An initialization execution confirming circuit 18 reads out the value recorded on a specific address of a nonvolatile memory 6 and the value recorded on a specific address of a ROM 9 or 10 for each time point of initialization like application of a power supply. Then the circuit 18 compares the contents of both values with each other to decide whether the contents of the memory 6 should be rewritten or not. If so, the contents of the ROM 9 or 10 are automatically read out and written in the memory 6. In case the circuit 18 forgets to supply the set value to the memory 6 or to supply the new set value, this fact is detected for each initialization like application of a power supply. Then the set value is automatically read out of the ROM 9 or 10 and stored in the memory 6. Thus the abnormal actions of a printer can be avoided and the reliability is improved for a copying system.

Title: Thin-film formation system
Inventor: MURAKAMI TOMOMI
IPC: C23C16/511
Filed: 1993-04-22
Abstract: PURPOSE:To prevent a deposited film from adhering to a dielectric member, by using an electrode connected to a high-frequency power supply with a given frequency range in a thin-film formation system, which includes a chamber, the dielectric for sealing an opening of the chamber and an electrode provided near the dielectric material. CONSTITUTION:An electrode 11 is provided on a face of a dielectric member 33 used for sealing an opening 27 of a chamber 27, and the electrode 11 has an opening 11a at the central part in a shape like an inner circumference of a waveguide 25. A high-frequency power supply with a working frequency ranging from 25kHz to 3MHz is provided outside the main system body 23. A deposited film adhering to the dielectric member 33 is reduced because the high frequency power supply with a high working frequency is not provided at the main system body 23. In this way, since an amount of deposited film adhering to the dielectric member 33 can be reduced, a ratio of operational stoppage caused by changing the dielectric materials or cleaning the system can be reduced, while a net working ratio can be improved.

Title: Automatic controller for set value of weight measuring device
Inventor: SAKAI YOSHIYUKI
IPC: G01G13/12
Filed: 1981-06-22
Abstract: PURPOSE:To increase the accuracy of the weight control, by securing an automatic control for the setting of the head level based on an error between the target value and the measured value or the cumulative value of the error. CONSTITUTION:When the weighing is over, the load signal is fed to a reversible counter 3 from a one-shot circuit 2. Then the value measured by a digital voltmeter (DVM) 1 is set to the counter 3. A comparator 4 compares the set value of the counter 3 with the value set at a target value setter 7. A clock pulse generator 5 feeds the pulse signal to the reversible counters 3 and 6 until the coincidence is obtained between the set value of the counter 3 and the set value of the setter 7. A reversible counter 8 subtracts the output with a command of UP/DN given from the counter 6. The output of a D/A converter 9 has a change equivalent to an extent obtained through the addition/subtraction done by the counter 8. The above-mentioned actions are repeated, and the output of the converter 9 receives an automatic correction so that the value of the DVM1 equals to the value of the setter 7.

Abstract: PURPOSE:To operate an equipment efficiently, by calculating and comparing operation durations per one wake-up of all pumps to make integral values of operation durations and integral values of the number of times of wake-up of all pumps uniform. CONSTITUTION:An operation duration integral value Hi (i=1-5) and a wake-up number integral value Si of each of plural water pumps 3 are calculated, and an operation duration Hi/Si per one wake-up of each pump 3 is calculated. If calculated results in all pumps 3 are equal to one another, a circuit 8 which determines the number of operated pumps on a basis of the signal from a water gauge 6 of a reservoir 4 and an operation order setting circuit 10 give a pump control command 13 to each pump through a pump controller 12 in accordance with a predetermined initial operation order. If calculated results Hi/Si in all pumps are not equal to one another, such operation order is determined in the circuit that pumps are operated in order from the pump having the minimum Hi/Si, and the command 13 is given to each pump 3 through the controller 12. Thus, operation integral times per one wake-up of all pumps are made uniform, and the concentration of the burden of the operation time and the wake-up frequency to a specific pump is prevented.
