Title: Valve mechanism
Inventor: SAKAI HIDEO
IPC: F16K37/00
Filed: 1985-05-30
Abstract: PURPOSE:To prevent overflow by providing a diaphragm chamber and an operating mechanism capable of opening a valve only when the diaphragm chamber is pressurized, thereby to close the valve on detecting the liquid surface and on stopping the supply of air to the diaphragm chamber. CONSTITUTION:When the liquid surface of oil rises to a position detected by a probe 8, the internal pressure in the probe 8 is increased so that a directional control valve 12 is switched to cut off the supply of air to a diaphragm chamber 28. Therefore, a diaphragm 37 is bent to the left by force produced by the upward movement of a spring S and a rod 36 to release locking of the rod 36. Accordingly, a lever 45 is turned clockwise to suspend lifting an operating rod 29. Thus, a pilot valve 22 is closed, and a main valve 21 is closed by liquid pressure flowing in a liquid pressure chamber 25 through a passage 27 to stop the supply of oil. So with the case where during the supply of oil, the supply of air to the diaphragm chamber 38 is cut off by a failure.

IPC: F02M37/10
Filed: 1997-05-06
Abstract: PROBLEM TO BE SOLVED: To sufficiently evade generation of delay of a fuel supply to an internal combustion engine based on remaining steam cushion when a fuel feed unit is restarted. SOLUTION: A feed pump is stored in a housing in which through flow is performed by fuel, a pressure chamber 40 is formed on the side of downstream of the feed pump from a flow direction point of view. The pressure chamber 40 is possible to be connected with an external chamber 44 via a valve 32. The valve 32 is provided with a first passing part 49 connecting the pressure chamber 40 with the external chamber 44 and a second passing part 53 having liquid flow Q2 flowing and passing around a closed member 34. Both of the passing parts lead to the external chamber 44 via a common opening 43. Thus, as liquid flow Q1 of the first passing part 49 is increased, a pressure difference is formed between the front and rear parts of the closed member 34 from a closing direction point of view and the closed member 34 moves from an open location 46 to a closed location.

Title: Cassette tape
Inventor: ISHII HIROSHI
IPC: G11B23/08
Filed: 1978-09-19
Abstract: PURPOSE: To make thinning-implementation design possible by increasing the degree of freedom as to head arrangement by reducing components in number by driving power from one system rotating at a constant speed when driving a cassette tape.  
     CONSTITUTION: When frictional wheel 14 turning at a constant speed comes in contact with belt 17 touching pulley 8 from power input window 13, belt 17 starts running at the constant speed, turning pulleys 8, 9 and 10 at the constant speed. Therefore, even if the take-up diameter of the tape varies, the outermost circumferential speeds of tape pulleys 11 and 12 are constatnt and no sag is generated. Although a magnetic head is inserted into a window made on cassette case surface 16, there is no need to arrange an element such as pinch roller on this surface, and consequently the magnetic head may be arranged freely on case surface 16, so that design for three-head implementation and auto-reverse function will be simplified. Further, its power is supplied from other than the largest surfaces of the cassette case, so that it can be made thin.

Title: Restorinig injection method
Inventor: ARAI TAMIO
IPC: E02D35/00
Filed: 1999-04-23
Abstract: PROBLEM TO BE SOLVED: To effectively correct settlement of a structure in the case of non-cohesive soil or in the case that a differential settlement has arisen by carrying out boundary injection below the bottom face of the structure and vein injection to subsequently inject an injecting slurry into the vein-like section and the boundary face. SOLUTION: A solution type injection material L is simultaneously injected from a plurality of injection pipes 5 obliquely inserted to the periphery of a box beam 1 to the periphery of the box beam 1a as a pretreating injection process to uniformize the peripheral ground. Thereafter, boundary injection or vein injection is carried out toward the downside of the bottom face of the box beam 1. Then, as a restoring injection process, an injection slurry is subsequently injected into the vein section in which vein injection has been excecuted and the boundary face in which boundary injection has been executed. The loose ground at the periphery of the structure is uniformized in advance in the pretreating injection process to prevent the injection material from leaking out to the peripheral ground.  And vein-like gel is developed at a crushed stone zone of the foundation and its periphery. Since fisher injection of such vein-like gel itself or injection into its layer boundary is apt to occur in the restoring injection process, the structure can be effectively uplifted by continuously injecting the injection slurry.

Title: Power control method by digital pwm
Inventor: UOSAKI YUJI
IPC: G05F1/10
Filed: 1999-04-23
Abstract: PROBLEM TO BE SOLVED: To stably supply power as designed while limiting the minimum value of the transmission cycle of a driver within an easily predicable range even when a current limiting means is operated by synchronizing timing to turn off the driver by the current limiting means to a reference clock and shortening the cycle of the reference clock rather than time for raising a load current from 0 A to a current limit setting value. SOLUTION: When the load current of a motor 8 exceeds the current limit setting value, a load current detecting means 9 validates an over current detecting signal. A current limiting means 10 latches the state of the over current detecting signal synchronously with a reference clock 1, when the load current of the motor 8 starts decreasing and gets smaller than the current limit setting value, the off signal of the driver 6 is invalidated and the load current of the motor 8 starts increasing. Since the cycle of the reference clock 1 is made shorter than time for raising the load current of the motor 8 from 0A to the current limit setting value, the load current of the motor 8 is not decreased to 0A.
