IPC: F16D43/20
Filed: 1996-04-11
Abstract: PROBLEM TO BE SOLVED: To improve a durability in operation of a bi-directional torque limiter without increasing a size of the product by a method wherein a pocket of an inner diameter surface of an outer ring is provided with neutral positions of rollers and formed with a plurality of sets of a pair of wedge-shaped cavities at both sides and the same number of rollers as that of the neutral positions are contacted from each other and assembled in it. SOLUTION: Both sides of a slit 18 at an inner diameter surface of an outer ring 3 are formed with a pair of pocket partition walls 22, a central symmetrical position of the slit 18 is formed with a pocket partition wall 22', a pocket 14 is formed between both sides of the pocket partition wall 22' and the pocket partition wall 22 and then six rollers 4 are assembled in the pocket while they are being contacted to each other. Then, the bottom surface of the pocket 14 is formed with the deepest neutral position 24 in correspondence with the roller 4, and a pair of inclination surfaces 25 gradually made to be shallow toward a normal or a reverse rotating direction of the outer ring 3.  A pair of wedge-shaped cavities 26 are formed between the inclination surface 25 and an outer diameter surface of the inner ring 2, and then the number of rollers 4 stored in the pocket 14 and the number of neutral positions 24 are coincided to each other. Since a plurality of rollers are assembled in the pocket without any clearance at all, the number of assembled rollers can be increased without increasing the size of the product and further a performance of surface pressure resistance can be improved.

Abstract: PURPOSE:To conduct a smooth volume control by connecting one end of a cylinder chamber to a discharge gas side and the other end to an oil pressure channel through a throttle pipe, connecting an oil exhaust passage of the chamber to a suction side of a compressor, and opening a slide valve with the discharge gas until the oil pressure rises. CONSTITUTION:A throttle pipe 22 is connected to a high pressure oil channel 20, and its end is connected to a cylinder chamber 15 through an oil feed pipe 18. A solenoid valve 17 is provided on the way of an oil exhaust pipe 19 connected to a suction side, and a passage 24 connects a cylinder chamber 14 to a discharge gas chamber 25. First, when a drive motor (not shown in the figure) is started, the discharge gas goes through a slide valve 11 and a hole 24 and acts on the cylinder chamber 14. Also, the oil pressure acts on the cylinder chamber 15. The high pressure oil 20 is delayed by a certain time due to the resistance of the throttle pipe 22, and a MIN load is maintained during this delayed time. In case of a Y-  start type motor, if the transfer from Y to   is completed during this delayed time, the starting current can be small, and the starting can be smoothly conducted.

Since the reflecting plate 100 is worked from the plate material, a cutting quantity is small, the material is reduced and time required for working is made short. Besides, three reflecting plates can be formed by one process and the profitability and manufacturing efficiency are improved.

Title: Two-phase fluid cylinder
Inventor: TAKEDA TSUTAE
IPC: F03G7/06
Filed: 1984-05-07
Abstract: PURPOSE:To realize a light weight and compact cylinder by sealing an operating fluid which can exist both as liquid and vapor at a given temperature in the cylinder. CONSTITUTION:An operating fluid which can exist both as liquid phase and vapour phase at a given temperature is sealed in a cylinder 1. Consequently, if the operating fluid in the cylinder 1 is heated, the vapor pressure rises and when the vapour pressure exceeds the outside force exerted on a piston 2, the operating fluid boils and moves the piston 2. On the other hand, if the operating fluid is cooled, the vapour is condensed and the vapour pressure decreases and the piston 2 is recovered. Thus, according to this structure, hydraulic pumps and piping are not needed and the cylinder can be light weight and compact.

IPC: H01L21/268
Filed: 1988-04-12
Abstract: PURPOSE:To apply optical energy of laser light efficiently to a substrate surface and realize sufficient gettering effects with small energy intensity by forming anti-reflection film on the substrate surface. CONSTITUTION:A semiconductor substrate 5 is fixed on a substrate holder 6 facing a direction of irradiation of laser light from back of the substrate so that it can be moved in vertically, laterally, frontward and backward by a front and back moving guide 4, a right and left moving guide 7 and an up and down moving guide 8. Laser light oscillated by an excimer laser 1 is irradiated to the semiconductor substrate 5 via a mask 2 and a lens 3. A SiO2 film is accumulated on the substrate by the normal CVD method and its thickness meets a condition that reflectance can be minimized. This enables energy of the laser light to be absorbed efficiently in the substrate and realizes sufficient gettering effects even if laser light of energy intensity smaller than it used to be is irradiated.
