Title: Measuring instrument for propagation time
Inventor: HABUKA YOSHIRO
IPC: G01B17/00
Filed: 1985-12-02
Abstract: PURPOSE:To obtain a measuring instrument which has the excellent reproducibility of measured values by making a comparison with a last propagation time measured value and deciding whether or not the data is inputted or not. CONSTITUTION:A trigger circuit 1 generates trigger pulses et and a measuring circuit 8 measures a propagation time. The output tN-1 of the circuit 8 which is measured with the (N-1)th trigger et is stored in a memory 10 and inputted to a difference arithmetic circuit 11 together with the next N-th measured value tN to calculate the absolute value DELTAt of the difference. The permissible value epsilon of the value DELTAt is set in a setting part 12 previously and compared 13 with the value DELTAt; when DELTAt<=epsilon, the circuit 11 reads the output tN of the circuit 8 and stores it in the memory 10. Said operation is repeated similarly and when the circuit 11 fetches a specific number of data, the measurement is finished and the result is displayed. When DELTAt>epsilon, the comparator 13 generates a reset pulse and resets the circuit 11 to its initial state, so that measurement is restarted through the operation of the circuit 1. Thus, the difference DELTAt from the last measured value is monitored and when the difference DELTAt increases, the measured value obtained so far is cleared and only a stable measured value is inputted, so that the measuring instrument with good reproducibility is obtained.

Title: Semiconductor integrated circuit device
Inventor: MOROOKA KIICHI
IPC: H01L27/02
Filed: 1984-12-21
Abstract: PURPOSE:To make it possible to ensure operational allowance, by providing a switch circuit, which controls the amount of current of a discharge circuit in correspondence with an operation control signal of a semiconductor integrated circuit device, in the discharge circuit between a substrate-potential and a reference-potential, thereby reducing the fluctuation of the substrate-potential due to the operation of the semiconductor integrated circuit device. CONSTITUTION:When an operation control signal has the same potential as that of a reference-potential wiring GND, a substrate-potential wiring VBB wiring is kept at a level, which is lower than the reference-potential wiring GND by the sum of the threshold voltages of field effect transistors Q11-Q15. When the operation control signal is increased to a potential, which is sufficiently higher than the threshold voltage of the transistor 15, the transistor 15 becomes a conducting state. and its potential is increased to the potentials of the gate and drain of the transistor Q14 and the reference-potential wiring GND. The current supplying capability of a discharge circuit 1 becomes large. Even if the semiconductor integrated circuit device is operated and the substrate- potential is decreased, the specified potential can be immediately restored and kept constant.

A compressor equipment to be controlled at a constant pressure value, in which labor is saved in the whole thereof, is thereby realized. Simultaneously, the capacity of a receiver tank 2 is reduced to downsize the whole of a device by controlling the turbo compressors at a constant wind pressure for starting and stop, and the efficient operation without generating a loss due to the blow- off is enabled by restricting the switching of load/unload.
