Title: Pump
Inventor: ABE MASAO
IPC: F04C15/00
Filed: 1983-01-19
Abstract: PURPOSE:To reduce frictional force while improving efficiency of a pump by balancing oil pressure produced between a casing and rotor rotating in the casing. CONSTITUTION:While oil is sucked into a space A1 to be compressed by the action of a slipper 7 and a cam surface of a cam ring 3, the volume of the space A3 varies slightly with the rotation of a rotor 2 and the oil pressure becomes smaller than that in the space A2 so that the slipper 7 is pressed hard against the cam surface by that oil pressure difference. Then, the internal pressure in the spaces A2, A3 are equalized by an opening 10 consisting of an extending- through groove 11 and an extending-thr#ough hole 12 communicating to the spaces A2, A3 to prevent friction between the slipper and the cam surface from increase. Also, instead of the opening 10, a groove 20 may be provided between the intake side plate 4 and discharge-side plate 5 of the rotor 2 so that the discharge side plate 5 is elastically deformed by high pressure and pressed against the rotor 2 side to prevent the increase of friction. The opening 10 and the groove 20 also function to forcibly lubricate respective parts.

Title: Remote controller
Inventor: SATOU KIYOHIRO
IPC: B66C23/90
Filed: 1983-01-21
Abstract: PURPOSE:To prevent the formation of dangerous state which an operator can not anticipate in crane operation by allowing a remote control function to be automatically suspended when a potentiometer circuit for setting or feedback is broken or short circuited. CONSTITUTION:When wire snapping is generated between the slider of a potentiometer 1 and a power source Vdd, a relay Ry2 is put into non-excited state, and a contact r2 is opened, and supply of voltage to the emitters of transistors 14 and 15 is suspended, and solenoid valves 7 and 8 are opened. Therefore, a piston 2 is positioned at a neutral position, and transfer of a hydraulic cylinder 27 is suspended. The contact r1 of a relay R1 is opened with a delay of 0.5sec. by the aid of a delayed timer 18, after the contact r2 is opened, and a solenoid valve 8 is closed to cut-off the working oil supplied by a hydraulic pump P. Thus, remote-control function is automatically suspended, and the formation of dangerous state can be avoided.

Counting output of the counter 6A gives address of the RAM3A, and transfer data from the processor 1B are written continuously in the RAM3A. When the content of the counter 6A arrives at a specified value, data transfer is regarded aa competed.

Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To provide an illumination system of a terminal unit (for example, portable telephone) which can suppress the uneven brightness of keys and can be constructed light, small, and thin. SOLUTION: On the rear surface of each key 2 of a portable telephone 1, a protrusion 7 is provided to press a switch 6 installed right under the key. A light emitting body 10 in a film form consisting of a moistureproof material is interposed between the key 2 and switch 6 and is provided with a hole 14 by means of punching, etc., so that the protrusion 7 presses directly a diaphragm 8 of each switch 6.

Title: Muffling device for submersible pump
Inventor: YONEMURA SHOICHI
IPC: F04D13/08
Filed: 1986-01-20
Abstract: PURPOSE:To reduce pressure vibration and mechanical vibration during operation by making the length of an expansion chamber partly formed with an elastic wall of a rubber etc. 1/4 the pressure pulsation wave length of the fundamental frequency and providing a stay for restricting the length of said elastic wall via a vibration isolating material. CONSTITUTION:A pressure pulsation wave generated from a submersible pump P is shifted by half a wave length from the pressure pulsation ware reflected at the expanded part or contracted part of an expansion chamber V having a length 1/4 of the wave length of the pressure pulsation, thereby causing them to interfere with each other to damp down the pressure pulsation of a fundamental frequency. Also, mechanism vibration from the pump P is insulated by the absorbing effect of the elastic flexible pipe 3 forming the expansion chamber V, without being transmitted to a pipe line. And,since the length of the flexible pipe 3 is restricted by a stay bolt 6 which is provided via a vibration isolating material 7, the elongation of the flexible pipe 3 due to the weight of the pump P or the inner pressure of the pipe line, and the vibration of the submersible pump P, can be prevented.
