Title: Control device for solenoid valve
Inventor: KURAMOTO HIROYUKI
IPC: F16K31/06
Filed: 1986-01-25
Abstract: PURPOSE:To reduce a fluctuation range of an actual speed with respect to a target speed, by detecting an actual operational condition of an actuator, and changing a duty ratio according to a detected value. CONSTITUTION:A deviation between an output signal from an actual position detector a and an output signal from a target position detector b is computed by an arithmetic circuit c. The deviation is inputted to a dead zone comparing section 11 and a high-speed signal determining section 12. If the deviation is equal to or approximate to zero, a solenoid valve 1 is not operated. When the deviation becomes large to reach a low-speed signal area, the solenoid valve 1 is controlled according to a duty ratio stored in a low-speed setting section 13. Further, when a cylinder is in operation, the operation speed is detected by a speed detecting circuit f, and is fed back to the low-speed setting section 13.

Title: Nonvolatile semiconductor memory device
Inventor: KOBAYASHI SHINICHI
IPC: G11C16/02
Filed: 1990-01-23
Abstract: PURPOSE:To prevent the threshold value of a floating gate from being depleted by a method wherein at the time of erasing, a tunnel is simultaneously generated in a first-layer gate oxide film and a second layer gate oxide film. CONSTITUTION:At the time of erasing, a drain 3 and a source 4 are grounded and a high voltage is applied to a control gate 1. Thereby, a tunnel phenomenon is generated between the gate 1 and a gate 2. Electrons which have been injected in the floating gate 2 tunnel an oxide film 6 by writing of an '0' and are emit ted in the gate 1. When the electrons are excessively emitted, a potential of the gate 2 rises, and electric field to be applied to an oxide film 5 rises and a tunnel is generated also in the film 5. Accordingly, the electrons in the gate 2 exist neither too much nor too little and the threshold value of a memory transistor is decreased by the writing of an '0', but is never depleted.
