IPC: F03B15/04
Filed: 1983-05-18
Abstract: PURPOSE:To simplify the construction of an equipment by connecting a stepping motor and the spool of a distributing valve to each other by a solenoid coil excited by a control power supply common to both the motor and the spool. CONSTITUTION:An electric signal from a speed-to-electric signal converter is sent to a pulse controller 16, which instantaneously issues the signal to a stepping motor 17 in the form of a pulse having a specified frequency. The stepping motor 17 makes step turns of a specified angle at a specified rate. Each stroke of the angle at which the stepping motor 17 is driven is transmitted to the spool 21 of a distributing valve 18 to operate the spool 21 for supplying a hydraulic servo motor 2 with pressure oil. The opening of the hydraulic servo motor 2 is detected by a position detector 19 and then fed back to the pulse controller 16 in the form of an electric current. The output signal from the pulse controller 16 is a digital signal, thereby permitting the equipment to be placed under open loop control.

Title: Rotary device
Inventor: URAYAMA MASASHI
IPC: G11B15/26
Filed: 1980-06-25
Abstract: PURPOSE:To ensure a stable rotation of a rotary shaft, by connecting in a body the 2nd flywheel to the 1st flywheel by making use of the empty weight of the 2nd flywheel. CONSTITUTION:Both levers 5 are set under the state as shown by the solid lines, and the tips of these levers are made to go apart from the lower face of the 2nd flywheel 2. Thus the wheel 2 touches on the upper surface of the 1st flywheel 1 by the empty weight of the wheel 2. Under such conditions, a rotary shaft 3 is turned by a drive motor 4. As a result, both wheels 1 and 2 turn in a body to ensure a stable rotation with a large moment of inertia. Then both levers 5 are turned toward arrows (a) centering on a support shaft 18, and thus the wheel 2 is lifted up by the tips of levers 5. As a result, the shaft 3 turns with only the wheel 1 to reduce the moment of inertia. Thus a rise is possible up to a prescribed rotational frequency in a short time.

Title: Device for changing over generator of power generation welding machine and welding machine only with welding rod
Inventor: ANDOU KENJIROU
IPC: B23K9/10
Filed: 1981-06-05
Abstract: PURPOSE:To perform titled changing over from remote places by operating a solenoid by supplying a battery current to relays and timers or closing a battery circuit only through melt sticking operation of a welding rod. CONSTITUTION:When a welding rod is melt stuck to base materials, the spacing between holders approach to no-voltage, and the battery current passing through the contact B of a relay X5 acts upon a timer T1 and at its setting time, a relay X6 operates to unlatch a relay X3. This forces a solenoid SOL to return to the home position, and an engine shifts to a low speed. The another circuit comming out from the timer T1 actuates keep relays KX1, KX2 with timers T2, T3 respectively, and the engine is again at a high speed by the operation of the SOL. At the same time, the battery current flows through the closed circuit of the relay KX2 and the contact B2 of the relay X7 which in turn operates a servomotor MS, thereby switching the welding machine to a power generator. When the leading end of the welding rod is brought into contact with the base materials, the battery voltage circuit is closed, and the MS is operated, by which the selection switch is changed over to the welding machine position.

Abstract: PURPOSE:To prevent a malicious call or wrong dial without change in a telephone line network by calling a call tone when the series of a consecutive time of a call signal is coincident with the preset series of the consecution time. CONSTITUTION:A call signal detection section 1 sends a call state signal through a call signal line l2 for a period when the call signal is received through a telephone line l1 and a comparison discrimination section 5 compares a timer value of a call signal timer section 2 with a desired timer value preset in a setting section 4 at the interruption of a call state signal. When the comparison discrimination section 5 discriminates the coincidence between the consecutive time of the call signal and the desired timer value, since a comparison coincidence signal is outputted from a control line l7, the control section 3 controls a line connection section 6 via a control line l8 to apply call by the call tone.

Abstract: PURPOSE:To provide a suction inlet for the center of guide block of internal gear pump and provide a discharge outlet for both ends in forward and backward rotation conditions to have unchangeable inlet and outlet even the rotation direction is changed, and to reduce numbers of parts of suction pipe system for simplifying the structure. CONSTITUTION:With a valve 16 closed, a valve 17 opened and a pump shaft 4 rotated as shown by arrow B, pinion 3 and ring gear 2 start also to rotate. Accordingly, part of left side outlet 7 of guide block 5 develops negative pressure owing to closing valve 16, negative pressure thereof sucks oil contained in inlet 6 and oil tank 8 to discharge from the right outlet 7. Further, with the valve 17 closed, the valve 16 opened and the shaft 4 rotated as shown by arrow C, the oil sucked from the inlet 6 allows to discharge from the left outlet 7. With such forward and backward rotation conditions, this enables to suck from the same inlet and discharge from either of right or left outlet 7 where an outlet may not be an inlet.
