Title: Servicing method of refrigerating cycle employing sealed motor-driven compressor as well as refrigerating cycle and refrigerating device
Inventor: SATO JUN
IPC: F04C29/02
Filed: 1997-11-26
Abstract: PROBLEM TO BE SOLVED: To make a recovery of refrigerant unnecessary upon services after second time and prevent so much affection of discharging of the refrigerant into atmosphere to global environment upon the disposal of a refrigerating device, by a method wherein the refrigerant is replaced with the refrigerant of HFC series and refrigerating machine oil is replaced with HAB or mineral oil upon replacing them in the service of a compressor. SOLUTION: A compressor 9 stores refrigerating machine oil 10 in a sealed vessel 2 and compresses refrigerant 21 to discharge the same. Upon replacing the compressor 9, refrigerant 21 is replaced with HFC series. The HFC series refrigerant does not contain chloride and, therefore, the destruction of the ozone layer is eliminated, and too severe affection to the global environment can be prevented even when the refrigerant is discharged into atmosphere, whereby the recovery work of the refrigerant is made unnecessary and the efficiency of the service replacement work can be improved. The refrigerating machine oil 10 is replaced with HAB or mineral oil.  A moisture adsorbing rate is reduced whereby deterioration or generation of acid is hardly occurred, and big problem will not be generated in the function of a refrigerating cycle even when air or water is mixed upon the service replacement.

Title: Valve system of engine
Inventor: NISHIMURA HIROBUMI
IPC: F01L1/26
Filed: 1989-12-13
Abstract: PURPOSE:To make it possible to obtain a swirl of suction air by actuating each suction valve by a different valve lift property with each low-speed cam, the cam nose part of which is different in shape, at the time of driving an engine at low-speed. CONSTITUTION:Relative motion between selectors 20 and 20' is allowed by making them in the state of no connection to low-speed locker arms 11 and 12 and high-speed locker arms 13 and 13' at the time of low-speed of an engine. As the high-speed locker arms 13 and 13' have no contact part to air intake valves 3 and 4 in this state, the oscillation of the high-speed locker arms 13 and 13' following the rotation of high-speed type cams 8 and 8' is not transmitted to the air intake valves 3 and 4 but the low-speed locker arms 11 and 12 oscillate in accordance with the rotation of low-speed type cams 6 and 7 and this oscillation is transmitted to the air intake valves 3 and 4. In this case, as the shapes of cam nose parts 6a and 7a of the low-speed type cams 6 and 7 are different from each other, a intake air swirl is formed and the combustibility at the time of low-speed is further improved.

Title: Fluorescent lamp lighting system
Inventor: TOKUSHIMA AKIRA
IPC: H05B41/24
Filed: 1996-10-29
Abstract: PROBLEM TO BE SOLVED: To remarkably reduce the leak of the electromagnetic wave, which is formed by an electric field and a magnetic field, by forming a piezoelectric transformer of a polarization part in outline or in the cross direction and a polarization part in the thickness direction so that the resonance characteristic in the thickness direction and the resonance characteristic in outline or the cross direction nearly coincide with each other. SOLUTION: A control unit 10 of a ballast, which is formed of a piezoelectric transformer, compares a current value, which is fed back from a fluorescent lamp 9' as a real load, and the reference signal inside of the control unit 10 with each other so as to adjust the operating point of the piezoelectric transformer. In the case where luminance of the fluorescent lamp 9' is low, an oscillating unit 12 moves the drive frequency to a low frequency on the basis of a command from the control unit 10 so as to increase the current to the fluorescent lamp 9'. In the case where luminance of the fluorescent lamp 9' is high, the drive frequency is moved to a high frequency so as to reduce the current to the fluorescent lamp 9'. Since a drive unit 13 amplifies the drive signal or raises the pressure, and applies it to the piezoelectric transformer 11, luminance of the fluorescent lamp 9' can be always maintained constant.

Title: Tip trapper for tube cock
Inventor: JIEEMUSU UISUSON EBUERETSUTO
IPC: F28F11/02
Filed: 1988-12-22
Abstract: PURPOSE: To prevent the forward end part of a tubular plug from dropping into a pipe upon breakage by locking and catching the plug. CONSTITUTION: When a pipe plug 201 is drawn out from a thin pipe 200 of a steam generator having a flaw, a tubular drive rod 310 having an integrally formed circumferential flange 320 is inserted coaxially with a screw hoe 280 into an inclining cavity 230. An outer shell expanding means 240 is pressed by the flange face 330 of flange 320. A compression member 420 is coupled slidingly with a catching member 380 through the head 370 of a coupling shaft 360. The compression-member 420 compresses the catching member 380 axially to press the bearing face 342 and expands the catching member 380 radially. Consequently, the catching member 380 is engaged with the first hole 250 of outer shell expanding means 240 which is thereby expanded radially and engaged with the outer shell 220.  Since the outer shell expanding means is engaged with the pipe plug when the forward end part 222 is broken off the outer shell 220, the forward end part can move through the pipe.

Abstract: PURPOSE:To efficiently remove dust particles inside an optical disk device and to enhance the reliability of the device by a method wherein a cleaner is mounted on the device. CONSTITUTION:In a cleaner 20, a dust collector 1 which has been housed inside a cartridge case 10 whose shape is the same as that of an optical disk medium is turned. Then, an air current gamma is generated inside an optical disk device 50; dust particles which are mixed with the air current gamma and circulated are adsorbed to the dust collector 1; the inside of the device is cleaned. When the amount of the dust particles which have adhered to the dust collector 1 reaches a limit value, the dust collector is taken out from the cartridge case 10, and the dust particles are removed. The dust collector 1 is made of a polycarbonate resin; it is always charged with static electricity.

Title: Compensated-off bias voltage feeding circuit
Inventor: DEIBITSUDO SHII MAKUKURUUA
IPC: H03K17/14
Filed: 1995-12-14
Abstract: PROBLEM TO BE SOLVED: To generate a bias voltage compensation which follows up the fluctuations of the power voltage and the processing parameter. SOLUTION: This bias circuit uses the potential dividers 21 and 23 which generate the divided voltage based on the power voltage VCC. These divided voltage are applied to the gate of a modulation transistor TR 28 of a current mirror which controls the current applied to a linear load device 34 which is biased in a linear area. The bias voltage is decided by the voltage crosses the load. Therefore, the fluctuation of the power voltage is reflected on the bias voltage, and the gate-to-source voltage of a series TR is kept constant against the fluctuation of the power voltage. Then the fluctuation of the processing parameter which generates the different TR current drive characteristic is reflected on the bias voltage that is generated by the device 34.
