Title: Hydraulically driven self-traveling device and mechanism for controlling driving speed thereof
Inventor: KIKUCHI MASAHIRO
IPC: B60K6/10
Filed: 1989-02-15
Abstract: PURPOSE:To obtain a pollution-free self-traveling vehicle by removably connecting a hydraulic power source to a self-traveling device via couplers, rotating a flywheel at a high speed by means of pressure oil from the hydraulic power source to accumulate energy and, after that, rotating a driving wheel with the flywheel as the driving source. CONSTITUTION:At the time of driving a self-traveling device, first, a hydraulic power source 22 driven by a prime mover 21 is connected to the self-traveling device via couplers 24 and a pressure oil from the hydraulic power source 22 is fed to a piston pump motor 2 under a condition of the maximum inclination angel of its swash plate 81 via a selector valve 23 to rotate a flywheel 1. When the rotating speed of the flywheel 1 becomes high speed, the selector valve 23 is switched over and the couplers 24 are disconnected. At this time, the swash plate 81 is made a right angle to a pump shaft 84 to eliminate energy consumption in in the piston pump motor 2. By switching over the next selector valves 3, 13, pressure oil discharged out of a sub-pump 12 which is driven by the flywheel 1 is fed to a piston motor 4 in normal/reverse directions thereby rotating driving wheels 6 in normal/reverse directions to advance/back the self-traveling device.

Title: Digital signal reception circuit
Inventor: FUKUOKA TAKASHI
IPC: H04L25/03
Filed: 1989-02-15
Abstract: PURPOSE:To effectively prevent an error at no signal by allowing a threshold voltage setting circuit to hold a proper threshold voltage extracted from a received signal and supplying the voltage to an identification device at no signal. CONSTITUTION:While a significant signal is inputted, an extraction circuit 12 extracts a proper threshold level from an input signal and supplies the result to an identification device 11 as the threshold level. The identification device 11 compares the inputted threshold level with the input signal to shape the waveform of the input signal. Moreover, an offset level setting circuit 13 is provided, which connects to an output of the extraction circuit 12 and supplies an offset voltage to the identification device 11 at no signal. Thus, even when the input signal is lost and the output of the extraction circuit 12 is lowered, the offset level setting circuit 13 references the data stored in an offset level storage circuit 17 and supplies a threshold level voltage at a proper level as the offset voltage, then no identification error is caused.
