Title: Semiconductor memory device and method of multi-writing
Inventor: NAKAMURA HIROISA
IPC: G11C17/12
Filed: 1998-05-12
Abstract: PROBLEM TO BE SOLVED: To provide a method of multi-writing in a semiconductor memory for preventing the device from being decreased in writing efficiency without enlarging a size of a transistor of a source switch. SOLUTION: When a four-byte multi-writing is performed, one byte is written in each of the four sectors SE1-SE4 simultaneously. In such a manner, the current, flowing through each source switch SW1-SW4 arranged in each sector SE1-SE4 corresponding one-to-one, becomes 1/4 of the currents flowing through the source switch when four bytes are written in one sector. Thus, the potentials of the source lines S1-S4 do not float even at the time of multi-writing, and transistors of the source switches SW1-SW4 is adequate without being enlarged in size.

Title: Electric discharge machine
Inventor: ITO TETSURO
IPC: B23H1/02
Filed: 1986-06-03
Abstract: PURPOSE:To prevent accidents due to damage of an electrode, by detecting the degree of insulation of an insulative machining fluid existing in the gap between the electrode and a workpiece and by comparing thus detected value with a reference value to control the quiescent time of pulse voltage applied across the interpole gap. CONSTITUTION:A control instruction signal generating device 17 superposes high frequency alternate voltage from an electrical sources 18 during a deionizing period or the quiescent time of pulse voltage applied between a wire electrode 2 and a workpiece 1 from a machining power source 15, and a current detector 6 detects interpole leakage current running due to the lowering of insulation of the machining fluid 3 which is caused by machined chips, so that thus detected current is compared with a preset reference value to discriminate the interpole condition. With the result of the discrimination a control instruction signal is fed to a control device 14 and the machining power source 15, and when the degree of insulation of insulative machining fluid 3 is lowered so that abnormal electric discharge occurs, the quiescent time is prolonged to give a more deionization effect to prevent electrical discharge concentration. Thus, it is possible to prevent breakage of the wire electrode without the machining rate being lowered.

Title: Control device for variable focal lens
Inventor: ONO YOSHIMI
IPC: G02B7/09
Filed: 1987-05-26
Abstract: PURPOSE:To simplify a variable power driving means by receiving the output of a focusing lens group position detector and a focal distance detector to control the variable power driving means, calculating the correction value of an image forming position deviation and driving focusing lens groups to focusing positions. CONSTITUTION:A maximum delivering distance arithmetic part 9 receives an output Zp from the focal distance detector 8 and outputs a lens delivering distance Fpx and focus position information at an infinite position. A proportional constant arithmetic part 10 receives an output Sx from the focusing lens group position detector 7 and the delivering distance Fpx and calculates a proportional constant Cfp. A variable power control part 16 rotates a variable power motor MZ. Since a focus motor MF is not driven, focusing lens groups 2a, 2b are held at fixed positions. Every movement of the variable power constitutional group by a prescribed distance, the lens groups 2a, 2b are driven by a focus control part 12. Since the control device is constituted so that the focus positions are changed by the outputs Zp, Sx in said constitution, the moving distances of the lens groups, 2a, 2b on the wide side are not unnecessarily increased.

Title: Semiconductor integrated circuit device
Inventor: IKEDA SHUJI
IPC: H01L27/11
Filed: 1989-05-24
Abstract: PURPOSE:To stably hold information by piling up the following: a gate electrode for a MISFET constituting a flip-flop circuit for a memory cell; a mask, for impurity introduction use, installed at the side of the gate electrode; a resistance element. CONSTITUTION:When a potential at a 'High' level is applied to a conductive layer 7D (gate electrode) for a MISFET Q1 and a potential at a 'Low' level is applied to a conductive layer 7C (gate electrode) for a MISFET Q2, an electric current from a wiring part VCC for power-supply voltage use flows easily in a resistance element 14B (R2). In addition, since the conductive layer 7C and a mask 9 for impurity introduction use shut off an electric field from a drain region 10 for the MISFET Q2, the electric current from the wiring VCC for power-supply voltage use becomes difficult to flow in a resistance element 14B (R1) (self-bias). That is, the resistance elements 14B (R1, R2) change their resistance values by information (voltage) written in a memory cell and can supply the electric current in a direction which clarifies a potential difference of '1' and '0'; accordingly, they can stably hold an electric charge to be used as information.

IPC: H01F7/16
Filed: 1989-05-24
Abstract: PURPOSE:To obtain a small and highly sensitive electromagnetic stepping actuator which is suitable for mass production and in which the stroke of movable pole can be maintained by providing means for feeding power having specific polarity to each coil and switching the polarity according to a specific order. CONSTITUTION:Upon power supply to a coil 5, a first ring pole 3 is magnetized to produce lines of magnetic force which are then lapped over those of a permanent magnet 1. When the lines of magnetic force shown by solid lines and doe lines are in same direction, attraction force functions between first and second ring poles 3, 7 while when they are in opposite directions, attraction force is cancelled between same poles. Consequently, a movable pole 8 moves by single step to the right as show at (c) and when power is fed to each coil 5 in the direction shown at (c), the movable pole 8 moves by single step to the left as shown at (a). By such arrangement, a small and highly sensitive electromagnetic stepping actuator suitable for mass production and having a long stroke can be obtained.
