Patent JP-H02283892-A (JP)
Title: Compressor
Inventor: IIO MASAHIRO
IPC: F04C29/00
Filed: 1989-04-25
Abstract: PURPOSE:To suppress the vibration of a rotor by pressing the rotor toward a side block side by gradually increasing the opening degree of many discharge valves along the side block side to another side block side where inlet ports are provided. CONSTITUTION:A drive shaft 4 is rotatably supported between the front and back side blocks 3a and 3b fixed on both sides of a cylinder 2, and a rotor 5 is fixed to the drive shaft 4. The volume of a compressing chamber 14 varies along with the rotation of the rotor 5, and as a result, compressed fluid pressingly opens each of discharge valves 16a to 16d and flows out from discharge ports 15a through 15d. In this case, the opening degree L1-L4 of the discharge valves 16a to 16d which are regulated by valve stoppers 17a to 17d is set so as to become proportional relationship that the internal pressure of the cylinder may become gradually high on the back side. In addition, the rotor 5 is pressed in the direction 3b of the back side block to suppress the vibration of the rotor 5. This leads to the reduction of the noise along with the vibration of the rotor 5.

Abstract: PURPOSE: To automatically accomplish the measurements of the radioactivity of clothes and the grouping of the clothes in accordance with their blot levels by disposing a radioactivity detector midway of the hanger conveyor of endless type moving vertically and by connecting the hangers for the clothes to the conveyor through a rail.  
     CONSTITUTION: If blotted clothes are hung on hungers and placed on a rail 4 moving downward, the hungers are conveyed to the endless hunger conveyor 1 so that they are hung on the hook of their upper running portion 1a. The clothes are elevated by the conveyor 1 to pass between a pair of midway radioactivity detectors 2 so that the radioactivities of the front and rear sides of the clothes are measured. Then, the clothes are conveyed to the lower running portion 1d of the conveyor 1 until they are transferred to a horizontal conveyor 5. A data processing unit 9 judges the blotted levels, which are measured at a detecting unit 2, so that the clothes are classified and selected in accordance with the levels. Then, a plurality of dropping devices 6a and so on are selectively operated to remove the clothes from the hangers so that they may fall down into the classifying baskets 7a and so on just below. The hangers are then carried down by the rail 8 so that they are recovered.

Filed: 1990-04-20
Abstract: PURPOSE:To obtain a high-quality recorded result with gloss removed from the surface of a recording medium by heating a medium for recording after a thermal transfer recording medium is separated from the medium for recording following thermal transfer recording process. CONSTITUTION:An ink sheet 3 sticks to a recording sheet 5 using a guide roller 12 and runs toward a head 4 with the recording sheet 5. The ink sheet 3 and the recording sheet 5 are pressed by the head 4 at a position of a head heat generation part 4a and are printed being pressed against a platen 25. After printing, the ink sheet 3 is separated from the recording sheet 5 at a position of a roller for peel-off purpose. After the separation process, the recording sheet 5 is heated on the nonrecording surface using a heating roller 14. The heating roller 14 incorporates a heater 15 and the recording sheet 5 is heated at higher than an ink melting point. Subsequently, the ink transferred to the recording sheet 5 by printing melts temporarily and follows fine projecting and recessed parts on the surface of the recording sheet 5 to form a delicate uneven surface. Furthermore, gloss disappears from the surface to provide a feeling of tranquillity.

Title: Electrically driven compressor
Inventor: ASA HIROTOMO
IPC: F04C29/06
Filed: 1997-04-23
Abstract: PROBLEM TO BE SOLVED: To suppress increase of a manufacturing cost of a compressor, and suppress vibration of the compressor by controlling an electric motor so as to generate on the electric motor torque fluctuation in a reverse phase of the torque fluctuation sensed by a torque fluctuation sensing means. SOLUTION: In a compressor, a lead wire of a rotation sensor 119 which senses a rotational position of a shaft 104 is connected to a controller which controls a motor MO through a connector 120. Torque required for driving a compression mechanism is varied as passage of time, interlockingly with rotation of the shaft 104. Electric current is carried to the motor MO by the controller so as to obtain the torque generated on the motor MO in a reverse phase of the required torque. It is thus possible to reduce vibration of the compressor with a simple means. It is also possible to prevent occurrence of noises of the compressor and reduction of life of the compressor caused by fatigue breakage of means such as a motor housing.
