Title: Control circuit for autonomous counters of a plurality of CPU's or MPU's
Inventor: YOKOYAMA YUKIO
IPC: G06F15/177
Filed: 1985-01-30
Abstract: In a control circuit for autonomous counters (41,42) acting as watchdog timers for a constantly operating first CPU (11) and intermittently operating second CPU (12) capable of transmitting data to and receiving data from each other, the first and the second CPU's respectively output first and second reset pulses (53) within prescribed intervals if operating normally. The first counter (41) is reset by the first reset pulses. The second counter (42) is reset by the second reset pulses when CPU (12) is operating and by the first reset pulses when it is not. The output of either the first or the second counter (on time out) is used to reset both CPU's. In a modification (Fig. 6) the counters are reset by the pulses (53) from their respective CPU's, but only the output of the first counter (41) is effective when the second CPU is not operating. …<IMAGE>…

Abstract: A low pressure gaseous hydrocarbon fuel storage system and power plant is described, which generally comprises means for storing a self-contained supply of a gaseous hydrocarbon fuel, a prime mover, means for conveying the gaseous hydrocarbon fuel to and from the storing means, and means for controlling the flow of the gaseous hydrocarbon fuel from the storing means to the prime mover. The storing means, which may include one or more vessels or cylinders, contains a predetermined sorbent material for reducing the pressure at which a given amount of the gaseous hydrocarbon fuel is stored. The prime mover, such as an internal combustion engine, has means for combining the gaseous hydrocarbon fuel with air to produce the mechanical energy therefrom necessary to move the vehicle. The conveying means is adapted to convey the gaseous hydrocarbon fuel to the storing means from a stationary source of the gaseous hydrocarbon fuel, and also to convey the gaseous hydrocarbon fuel from the storing means to the combining means of the prime mover during the operation of the vehicle. In the preferred embodiment, the maximum pressure at which the gaseous hydrocarbon fuel is stored in the storing means is in the range of approximately 100 psig to approximately 400 psig. <IMAGE>

Title: Interferometric multicoordinate measuring device
Inventor: JAGER GERD
IPC: G01B9/02
Filed: 1986-01-16
Abstract: A known interferometer for the incremental scanning of variable interference structures having a diaphragm 3 between the interferometer splitter 30 and the beam splitter 2, and CCD arrays 40 integrated into the interferometer, is provided for each coordinate direction such that a mutual angle of 90 DEG  is achieved between the measuring beams IMX, IMY of the interferometers, and that, in the case of two-coordinate measuring systems, planar linear reflectors M???, M??? are associated with the measuring beams and, in the case of three-coordinate measuring systems, planar reflectors are associated with the measuring beams. An interferometric multicoordinate measuring device is described which, despite considerably simplified constructional and technical expenditure on the guide system or systems of the working means, guarantees an extremely high degree of measuring accuracy. Furthermore, the proposed solution enables for the first time ever interferometric-incremental measurement to be carried out in translatory moving drive systems but not in drive systems guided in separate cartesian coordinates. <IMAGE>

Title: A pressure regulator for a fuel gas
Inventor: SUZUKI HIROSHI
IPC: F23K5/00
Filed: 1986-03-27
Abstract: A pressure regulator for a fuel gas of the present invention operates to reduce the pressure of the fuel gas kept in a gas container to the predetermined pressure and then supply it to a burner through the secondary passage thereof. Further, the pressure regulator includes a shutoff valve disposed in the primary passage thereof and an actuator of which operation chamber connects to the secondary passage. In the shutoff valve, there is provided a valve body displaceable between the valve open position and the valve shutoff position and sustained in the valve open position by the attractive force of a magnet against the valve closing force by a valve closing means in the normal condition. In case the pressure in the secondary passage is increased abnormally, the actuator is driven by the increased secondary pressure so as to move the magnet away from the valve body and hence to close the primary passage by the valve body.

Title: Composite microwave phase shifter
Inventor: ANDRE CHARLES
IPC: H01P1/185
Filed: 1986-10-22
Abstract: A microwave phase shifting device comprises, in series, two diode phase shifters (DD1,DD2), operating respectively at 180 and 90{, and followed by a ferrite phase shifter (DF). Command circuits (CD,CF) respectively associated with the phase shifters are subject to a general numerical control (CG), suitable for subdividing 360{ into phase increments of a given resolution. The reproducibility is improved by the fact that the control of the ferrite phase shifter (DF) is effected from calibration values that can be obtained by adjusting, in a calibration state, the values obtained from the ferrite phase shifter (DF), starting with values available with the aid of the other two phase shifters (DD1,DD2).

IPC: G01P3/80
Filed: 1987-01-07
Abstract: The velocity of a moving elongate element such as a cable 1 is measured by illuminating at least a part of the element at first and second positions spaced a known distance along the axis of movement thereof. A variation in the physical configuration of the element, e.g. its width or the profile of one surface of the element, changes the amount of illuminating radiation obscured by the element.
