Title: Controller of hydraulic driving machine
Inventor: KASHIWAGI MASAO
IPC: F15B11/02
Filed: 1996-09-25
Abstract: PROBLEM TO BE SOLVED: To prevent/reduce slow-down of actuator speed when an oil temperature is low by providing a switching valve with a first switching location leading maximum load pressure of an actuator to the other pilot chamber of a regulator valve and a second switching location leading pump pressure to the pilot chamber. SOLUTION: A three-port and two-location switching valve 15 is normally located at a first switching location 15a by a spring 16 and leads maximum load pressure of an actuator selected by a shuttle valve 10 to the other pilot chamber 9b of a regulator valve 9. When the switching valve 15 is located at a second switching location 15b by the operation of a lever 17, pump pressure of a high pressure passage 1 is led to the pilot chamber 9b. Thus, differential pressure of pump pressure and maximum load pressure of the actuator, that is, differential pressure of about 2a to 5a of variable throttles of control valves 2 to 5 can be increased. Therefore, more flow rate is secured by increased differential pressure at the second switching location 15b when an oil temperature is low and slow-down of actuator speed can be prevented/reduced.

Title: Driving circuit for safety valve
Inventor: IWATANI YOSHINORI
IPC: F16K31/02
Filed: 1990-10-12
Abstract: PURPOSE:To enhance the safety by providing a trouble detector for detecting a short-circuiting trouble of a semiconductor switch at each switch connected in series with a safety valve, and opening the other switch by a detection signal of each detector. CONSTITUTION:When a power source 4 is connected, a voltage VF of a transistor 11 is not yet generated at this time, and hence an input of an input terminal 13a of a comparator 13 becomes a voltage obtained by dividing a power source voltage E by resistors R11, R12. On the other hand, an input of an input terminal 13b becomes a voltage obtained by dividing the voltage E by resistors R14, R15, and the output level of the comparator 13 becomes 'L'. Thus, a transistor 14 is turned ON, a transistor 16 is turned ON, and an output terminal 12a of a trouble detector 12 is grounded. Accordingly, a transistor 21 cannot be turned ON, a semiconductor switch 2 also remains OFF, and the voltage E is not applied to an operation coil 3a, and hence a safety valve 3 is not opened.

In this case, the current flowing period of the resistor 9 stops operating of the forward thyristor converter 3 to eliminate the circulating current. Thus, the current direction of the load coil 11 can be readily inverted without generating a current zero zone at current inverting time.

Abstract: PURPOSE:To exactly discriminate two various television broadcasting signals at high speed by providing a hysteresis comparator to extract a pulse with an amplitude which upper end is more than a prescribed first threshold value and lower end is less than a prescribed second threshold value. CONSTITUTION:A frame synchronizing pattern is extracted from a received television signal by a band pass filter 12 and the extracted signal is delayed for one horizontal scanning period. Then, the phase of the signal is inverted and the frame synchronizing pattern is detected by detecting correlation between the inversion output and delay output by a correlation detector 17.

Title: Hydraulic cylinder
Inventor: RO AKINORI
IPC: F15B15/22
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of an impact by a method wherein a load is effectively absorbed in the vicinity of the stroke end of a hydraulic cylinder. SOLUTION: When a hydraulic cylinder 20 is expanded and a cushion ring 12 is fitted in a head cover 3, a chamber 4b on the rod side forms a cushion chamber, and since return oil flows out through an annular flow passage between the cushion ring 12 and the head cover 3, a cushion pressure is generated. The cushion pressure is relieved by a two-stage relief valve 23 of low and high pressure relief valves 24 and 25. Right after the starting of a cushion stroke, the degree of the increase of a cushion pressure is controlled through relief of the low pressure relief valve 24. Thereafter, a cushion pressure is remarkably increased, and during the increase of the cushion pressure, a load is effectively absorbed. The high pressure relief valve 25 is relieved and a cushion pressure is rendered approximately constant.

Title: Generating engine brake system for tracked vehicle
Inventor: YAMAMOTO SHUNEI
IPC: H02P9/04
Filed: 1995-10-24
Abstract: PROBLEM TO BE SOLVED: To obtain the same braking effect as that of a mechanical braking by regenerative braking. SOLUTION: An engine 1 is coupled with a permanent-magnet three-phase synchronous generator 2, to which rectifiers 3, 4 and a generating section inverter 5 are connected. To the rectifiers 3, 4, right and left traveling inverters 6, 7 are each connected with a power regenerative unit 10 installed between them. Three-phase AC from the generator 2 is converted by the rectifiers 3, 4 into DC, which is converted into AC by the inverters 6, 7 to drive the right and left permanent-magnet three-phase motors 8, of a tracked vehicle. The motors 8, 9 are switched over to a generator mode with regenerative power when the brake is applied. The AC so generated is converted by the inverter 6, 7 into DC, which, as a constant voltage, is returned to the inverter 5 via the power regenerative unit 10.  With the AC generated here, the generator 2 is switched over to a motor mode to reverse drive the engine 1, and thereby an engine brake effect is obtained.
