Filed: 1985-04-18
Abstract: PURPOSE:To obtain a gas laser oscillator which can control the preliminary discharge to a minimum level and can supply a maximum energy to its main discharge section, by holding a high-voltage electrode with a capacitor. CONSTITUTION:In the present gas laser oscillator, a capacitor 10 is interposed between a support plate 2a and an attachment plate 3 while the ends of the capacitor are connected to the respective plates. A high-voltage pulse power supply 9 consists of a high-voltage power supply 9a, a charge resistance 12 and a main discharge capacitor 13, and a circuit is constructed such that the electric charge for charging the main discharge capacitor 13 flows through a cathode 5 and an anode 6. The charge of the main discharge capacitor 13 is transferred to the capacitors 8 and 10 through inductances 15, 16 and 17. The maximum rate of transfer can be obtained when the parallel capacity of the capacitors 8 and 10 is equal to that of the main discharge capacitor. Accordingly, if the capacity of the capacitor 10 is decreased to its minimum possible while the capacity of the capacitor 8 is increased to its maximum possible, the maximum rate of transfer can be obtained without consuming unnecessarily large energy for preliminary discharge.

Abstract: An on board vehicular data processing system samples vehicular operating parameters such as fuel level, distance travel, etc. The system calculates values of other parameters such as range and travel time. Under control of the position of the ignition key, which assumes positions representative of modes of operation, OFF, PARK, TRIP, START, the system displays indications of a limited number of sensed and calculated parameters, the particular indications being those which are most useful for the instant mode of operation represented by the position of the ignition key. After a trip, system parameters may be stored for future reference by a predetermined sequencing of the ignition key position. Such storage may be cleared by a second sequencing of the ignition key positions. Parameter reference values may be stored as maximum or minimum and present values for a parameter may be compared with the maximum or minimum and an alarm indication given, acoustical or optical.
