Title: Gas rate sensor
Inventor: HOSOI TAKASHI
IPC: G01C19/00
Filed: 1991-06-14
Abstract: PURPOSE:To obtain necessary rate sensitivity and enable detecting anglular velocity with good accuracy by using a gas with small thermal conductivity. CONSTITUTION:The gas flow discharged from a nozzle hole 3 in upper and lower semiconductor base 2, 1 being contacted to a gas path 4 is deflected by the effect of anglular velocity. The direction and degree of the deflection are detected by the output difference between a pair of heat wires 51, 52 in a bridge part 6 formed by etching the base 1. The efficiency of the radiation from the heat wires 51, 52 into the gas is determined by the thermal conductivity and the surface temperature of the wires 51, 52 and detection accuracy is degraded by the lowering of the surface temperature if a gas with large thermal conductivity is used. Therefore, by using such low thermal conductivity gases as N, Ar, necessary rate sensitivity is obtained without too much lowering of the surface temperature of the wires 51, 52 and accurate detection is possible without being affected by gas convection.

Filed: 1988-09-27
Abstract: PURPOSE:To prevent the flowing of overcurrents for a prolonged time through a head coil by installing a timer circuit timer-set by the output signal of an overcurrent detector and outputting an interruption signal for starting divided printing to a CPU from the circuit. CONSTITUTION:Overcurrents are detected by an overcurrent detector 7 at the starting time of 100% printing, and a timer circuit 10 is set. The timer circuit 10 transmits an interruption signal for starting divided printing after a specified setting timer time passes over a CPU. The CPU starts divided printing, but large charging currents are made to flow through an output capacitor 9 until voltage is recovered to V0 because voltage is made lower than rated output voltage V0 by 100% printing up to that time, and the timer circuit 10 is reset when output voltage is recovered to rated output voltage V0. Accordingly, flowing for a prolonged time through the coil of a head of overcurrents without being affected by an ambient temperature can be prevented.

IPC: E02D5/20
Filed: 1997-09-08
Abstract: PROBLEM TO BE SOLVED: To provide a cleaning machine for joint between walls of an underground continuous wall capable of smoothly cleaning the joint between walls by reducing resistance to a brush part without degrading cleaning capacity. SOLUTION: A brush part 21 rubbing and removing attached substance stuck to a joint between walls is fitted to a cleaning machine main body 20 so as to be slanted against the projecting direction of the joint between walls. When the cleaning machine main body 10 is vertically moved, because the brush part 21 rubs the joint line while point-contacting with it without simultaneously contacting with the joint line, resistance against the brush part 21 is remarkably reduced compared with a conventional case, and because the joint line is rubbed with the brush part 21 extending over the full length, resistance against the brush part 21 can be reduced without degrading the cleaning capacity, and the joint between walls can be smoothly cleaned.
