Title: Hydraulic circuit for hydraulic shovel
Inventor: IMAI TOSHIYUKI
IPC: E02F9/22
Filed: 1986-06-03
Abstract: PURPOSE:To enable soil to be quickly excavated and discharged, by providing a hydraulic circuit for connecting a hydraulic pump to a change-over valve for swing, or a hydraulic circuit for connecting the change-over valve for swing to an oil tank, with a speed-regulating valve for enabling the opening to be freely set. CONSTITUTION:When the set pressure of a pilot pressure-reducing valve 12 is set to be 0, then the pressure of the pilot duct line 11 of a pilot hydraulic circuit comes to approx. 0. A speed-regulating valve 9 is put at a position 9a for full admission by the pressure of a spring 10, and the inflow of pressure-oil fed from a first hydraulic pump 1 to a rotary motor 8 is not limited. In case that a boom is desired to be taken to a high position quickly, when the set pressure of the pressure-reducing valve 12 is heightened, then pilot pressure is worked on the regulating valve 9 through the pilot duct line 11, and the opening is narrowed down, and the inflow of pressure oil to the motor 8 is suppressed. Accordingly, the rising speed of the boom is relatively increased by the reduced speed component of the rotary unit.

Title: Reset signal generating circuit
Inventor: ISHII SHIGETAKA
IPC: G06F1/24
Filed: 1978-10-18
Abstract: PURPOSE: To prevent the fault detecting circuit from detecting the fault even in case short break is caused when the power source is thrown in by giving a forced driving control to the reset signal generating circuit to the reset signal generating state with reception of the output power detecting signal of the main power source.  
     CONSTITUTION: In case the short break is cused at the throw-in time of the power source, output voltage +VC 1  of main power source 11 begins to lower. Accordingly, output voltage +VC 2  of DC-DC converter also lowers. At time moment, the output voltage of source 11 is detected at the voltage drop detecting part (comprising resistors R15 and 16, constant voltage diodes D17 and D18 plus photo coupler 19). Then the output transistor of coupler 19 is turned off when the inter-terminal voltage of R16 beomes lower than the Zener voltage of D17. Thus the terminal voltage of capacitor 5 in the reset signal generating circuit varies to "0", and the reset signal is supplied to digital operation part 13. Accordingly, the reset signal is always generated at the short break time irrespective of the intermittent time of the short break occurring at te throw-in time of the power source. In this way, the fault detecting circuit can be prevented from detecting the fault even in case the short break is caused.

Abstract: PURPOSE:To make it possible to operate the separation of an armature smoothly by forming rotary shafts with a non-magnetic substance, and generating no residual magnetism in the rotatary shafts when the current flow is stopped. CONSTITUTION:The first rotary shaft 20 is formed of a non-magnetic material and penetrated through the center penetrating hole 22 of an electromagnetic coil 16.
