Abstract: PURPOSE:To improve the capacity and the reliability by fitting spiral blades into two spiral grooves made in a rotary body while inclining in the opposite directions and partitioning the section between the inner circumferential face of a cylinder and the outer circumferential face of the rotary body with the blade into a plurality of working chambers. CONSTITUTION:In a compressor 1, two spiral blades 15, 16 are wound around a piston 10 while inclining in the opposite directions and refrigerant gas is sucked from the opposite sides of the piston 10 into a cylinder 7. The refrigerant gas is then carried to the intermediate section of the piston 10 while being compressed and delivered into an enclosed case 2. Since the refrigerant gas is sucked from two directions, carrying capacity can be increased without enlarging the pitch of the grooves 13, 14 and the size of the cylinder 7 and the piston 10. By such arrangement, the efficiency can be improved without causing excessive stress in the blades 13, 14 and a high capacity compressor can be obtained. Furthermore, suction efficiency is improved because the suction ports are provided at two points.

Title: Image former
Inventor: WATANABE JUNJI
IPC: B41M5/52
Filed: 1984-08-17
Abstract: PURPOSE:To miniaturize an image former by providing a coil spring between the first presser to be coupled with the axial periphery of a thermal head drive shaft and the second presser fixed to the drive shaft. CONSTITUTION:When a thermal head is separated from a platen, an aperture (delta1) is present only on one side between the projection 128 of the first presser 123 and the groove 127 of a drive shaft 126. The length of the coil spring 132 becomes l1-natural length. When a motor 83 is driven and the drive shaft 126 is turned to the direction of arrow X, the first presser 123 is turned through the second presser 129 and the spring 132 and the thermal head is driven toward the direction of platen through a rod 75. The second presser 129 is further turned and the spring 132 is extended to a length (l2)<(l1). An aperture (delta2) is formed in the opposite direction of the aperture (delta1), and the thermal head is pressingly contacted with the platen. The coil spring can thus be made smaller to permit the miniaturization of the device.

Title: High frequency feeding bus bar
Inventor: SUGANO SATORU
IPC: H02G5/10
Filed: 1998-06-18
Abstract: PROBLEM TO BE SOLVED: To provide a high frequency feeding bus bar, in which an opposite area of conductors to each other has a same value in spite of switching of a feeding zone so that electromagnetic coupling between them is dense to improve an efficiency. SOLUTION: Four inner conductors 22-25 with their hollow portions as cooling flow passages 27 are rectangularly disposed in four sides. A hollow-shaped outer conductor 21 is disposed outside of the inner conductors 22-25, while insulating layers 26 are provided between the respective conductors 22-25. Feeding to one zone B is performed by a combination of two inner conductors 23, 24 in opposite angle positions and the outer conductor 21, while feeding to the other zone A is performed by a combination of two inner conductors 22, 25 in opposite angle positions and the two inner conductors 23, 24. Thereby, because an opposite area of conductors 21-25 to each other can have a same value regardless of feeding to either of the zones A, B, electromagnetic coupling can be condensed to improve an efficiency. Besides, adjustment of a high-frequency resonance is simplified.

Filed: 1988-07-08
Abstract: PURPOSE: To attain size reduction in a transmission by rotating a rotatable chuck assembly by a two speed transmission composed of a planetary gear transmission, and changing a speed in two stages by pressing force of a frictionally meshing surface. CONSTITUTION: Rotation of a motor shaft 32 drives a chuck head in rotation through a chain by a sprocket wheel SW through an external teeth gear 22 of a planetary gear transmission. In this case, when a ring gear 56 is moved rightward by a lever 118, it is fixed by contact between surfaces 60 and 72, and rotation of the gear 22 is transmitted to the sprocket wheel SW through a sun gear 24, a planetary gear 40 and a carrier plate 38. When the ring gear 56 is moved leftward by the lever 118, surfaces 58 and 66 contact with each other, and the gear 22, the sun gear 24, the ring gear 56 and the planetary gear 40 are integrated, and rotation of the gear 22 is directly transmitted to the sprocket wheel SW through the carrier plate 38. In this way, speed can be changed in two stages without generating a noise by a small device.

Title: Spectacle machining data display unit
Inventor: KITAO IKUO
IPC: B24B9/14
Filed: 1997-06-27
Abstract: PROBLEM TO BE SOLVED: To easily judge the codes of (+) and (-) by an operator, by comprising a display means which performs the inverted display when the code of the input machining data of the spectacle lens is changed. SOLUTION: When a numerical value can be changed, for example, when the numerical value +2.00 is changed to, for example, -1.00 by the operation of a keyboard part, (-) is sometimes taken (+) when -1.00 is kept as it is, which causes the failure in the machining. When the keyboard part is operated to change the numerical value, for example, when (+) is changed to (-), the inverted display of the numerical value and/or the code is performed by a liquid crystal display part 3 like a display of UP, as shown by the oblique lines. Whereby the judgement can be easily performed in comparison with a case when only the display of the numerical value and the (+) or (-) are changed. The input of the incorrect machining data can be prevented.
