Title: Position detecting apparatus
Inventor: SHIMIZU OSAMU
IPC: G01S19/49
Filed: 1989-04-17
Abstract: PURPOSE:To continue stabilized road matching navigation for a long time by correcting the present position of a vehicle with the estimated position of the vehicle in radio navigation method based on the result of the evaluation for the position of the vehicle which is obtained by the road matching navigation. CONSTITUTION:A GPS receivers 7 measures the arriving times of radio waves from three - four satellites and computes an estimated position PG of the own vehicle on the ground. Meanwhile, a processor 8 computes the vehicle position based on the data from a bearing sensor 3 and distance sensor 4. Pattern matching between said data and the road network data of a road map memory 5 is formed. Then, the similarity of the vehicles on each road and the probability regions of the vehicle presence (CEP) are evaluated. When ratio navigation is required in correspondence with the result, the vehicle position is corrected by using the estimated vehicle position PG based on said satellites. Therefore, the vehicle position is not largely deviated, and the stable road matching navigation can be continued for a long time.

Title: Coil drive circuit
Inventor: OOTSUKI KANEICHI
IPC: G11C19/08
Filed: 1979-07-31
Abstract: PURPOSE: To reduce the power consumption and temperature rise, by performing injection and absorption of energy in the resonance circuit depending on the amplitude of resonance current required in coil drive control to obtain specified current value.  
     CONSTITUTION: Control pulse is fed to the input terminal F and the coil L is connected to the electric power supply -E 0 . The drive pulse and control pulse are  input to the AND gate G. The switch O 3  is conductive with this AND output and  the current i 2  is given to the resonance circuit consisting of the coil L and the capacitor C through the resistor R from the electric power supply +E 1 . As a result, the  coil current i 1  increases, and the increment is greater as the voltage E 1  of the power  supply +E or the injection time is greater, or the resistance of the resistor R is  smaller. Thus, the normal drive current is set smaller within required range and it is injected to the resonance circuit with the control pulse only when greater current is  required, then power consumption and temperature rise can be reduced.

Title: Puffer gas-blast circuit breaker
Inventor: KIKKO YOSHIAKI
IPC: H01H33/70
Filed: 1999-04-05
Abstract: PROBLEM TO BE SOLVED: To enhance the shutoff performance of a puffer gas blast circuit breaker without causing large-sized construction of the operating mechanism. SOLUTION: The space inside a movable contact piece 5 and a slide rod is used as a pressure boost chamber 17, and a pressure booster tube 18 consisting of a sublimating material is installed in the chamber. When the current is shut, the tube is sublimated with the thermal energy of arcs 19, and gas is emitted to raise the internal gas pressure of the chamber 17. When the nozzle 4 is set off from a stationary contact piece 3, the high pressure gas in a puffer chamber 16 due to a puffer cylinder 7 and a high-pressure gas in the chamber 17 due to the sublimating material are fed blowing to the arc, which is thereby extinguished. Thus only addition of the tube 18 allows establishing enhancement of the shutoff performance without requiring enlargement of the operating mechanism.
