Title: Variable power device
Inventor: WATABE SUSUMU
IPC: G03G15/041
Filed: 1983-09-29
Abstract: PURPOSE:To reduce the number of used mirrors and to reduce the cost considerably by providing a means where variable magnifications are inputted, a means which controls the position of an optical system to drive a lens, and a means which controls the timing of paper supply. CONSTITUTION:A device is so constituted that the first mirror 11 and a lens 12 are moved on a basis of a photosensitive drum 14 in case of varying of magnification, and extents of movement DELTAM and DELTAL are calculated when a reduction magnification is inputted. The first mirror 11 is moved left for the extent DELTAM, and the scanning start position of a moving platen 10 is separated from the position of the mirror 11, and the time spent in scanning for the extent DELTAM is longer than that for unmagnification. Scanning is performed with a platen signal, and paper is supplied with a form start signal when a set time t2 obtained by calculation elapses, and the front end of the form is positioned, and copying without positional slippage is executed. Consequently, expenses required for high- precision attachment of mirrors are reduced considerably because only two mirrors 11 and 13 are used.

Title: Non-volatile semiconductor storage device
Inventor: IWAHASHI HIROSHI
IPC: G11C16/06
Filed: 1983-09-28
Abstract: PURPOSE:To keep the value of writing current almost constant by changing the gate voltage of a write control MOS TR or column selecting MOS TR in accordance with the value of the writing current. CONSTITUTION:A high voltage VP due to a decoded output X is impressed to the gate of a memory cell 11 and injected into an electron floating gate at the generation of impact ionization to write data. At that time, large current is made to flow into a course consisting of a resistor 21, MOS TRs 13, 12 and the memory cell 11. When the current is made to flow into the resistor 21, a potential difference is generated between both the ends of the resistor 21 and a voltage VA smaller than the VP is obtained from a serial node 22. If the current flowing into the resistor 21 is constant, the voltage VA is also constant, output voltage VB from a control circuit 30 is also fixed and the ON resistance value of the MOS TR13 is also fixed, so that the constant current is kept as it is.
