Title: One-way clutch
Inventor: TAKAGI MASAYUKI
IPC: F16D41/07
Filed: 1995-08-01
Abstract: PROBLEM TO BE SOLVED: To reduce volume of a one-way clutch compared to a conventional one, enable weight reduction, reduce edge load for eliminating unevenness of load distribution, and improve durability for the load by forming a recession on an end face of a power transmission member such as a sprug, a cam or a cylindrical roller. SOLUTION: When an outer ring 1 is fixed and an inner ring 2 is rotated counterclockwise, a sprug 3 is tilted clockwise for preventing transmission of the rotation of the inner ring 2 to an outer ring 1. On the contrary, when the inner ring 2 is rotated clockwise, the sprug 3 stands counterclockwise for transmitting the rotation of the inner ring to the outer ring. A recession 31 is formed on an end face of the sprug 3 by pressing or the like, volume is reduced comparing with a conventional one having the same outer configuration for reducing weight. Due to the presence of the recession 31, a load is received by a thin portion 32 of the sprug 3, so that the load receiving portion is flexible. Load application is reduced near the end face for equalizing the distribution.

Title: Optical waveguide
Inventor: HANDA YUUICHI
IPC: G02F1/125
Filed: 1983-12-02
Abstract: PURPOSE:To suppress the optical damage of an optical waveguide and to enable guiding of a wave up to a high light power level by providing a means for applying a surface acoustic wave which impresses the surface acoustic wave on the part where the guided light is propagated. CONSTITUTION:Titanium is thermally diffused at high heat on the surface of a base plate 6 consisting of a lithium niobate crystal to form a waveguide layer 7 on the surface of which grating couplers 10, 11 are provided. Comb-shaped electrodes 8, 9 for exciting a surface acoustic wave are set so as to coincide with the propagating direction of the guided light. If the surface acoustic wave is progated in the above-mentioned way, the excess electric charge is transported in the propagating direction of the surface wave and the localization of the charge which is the cause for an optical damage is suppressed. The output light 13 taken out by the coupler 11 is therefore guided up to a high power level as the optical damage is suppressed.

Title: Vane type rotary compressor equipped with capacity varying mechanism
Inventor: NAKAJIMA NOBUFUMI
IPC: F04C28/10
Filed: 1986-09-25
Abstract: PURPOSE:To control the capacity to the optimum value according to the outside and inside variations by adjusting the pressure in a pressure chamber by operating one control valve according to the increase and decrease of the pressure in a low pressure chamber and installing the other control valve for adjusting the pressure in the pressure chamber according to the outside signals. CONSTITUTION:When a driving shaft 4 revolves, a vane revolves along the inside surface of a cylinder 1, together with a rotor 2, and the capacity of a compression chamber 8 varies. Therefore, after the gas introduced into a low pressure chamber 10 from a suction port 12 is compressed in the compression chamber 8, said gas is discharged from a discharge port 13. In this case, if the pressure in the low pressure chamber 10 is high as in case of the low pressure operation, the bellows 41 of the first control valve 35 is contracted to reduce the opening area between a valve body 37 and the first valve seat 38. The pressure in each pressure chamber 28a is increased so as to be close to the pressure in the high pressure chamber 11, so far as the second communication passage 48 is throttled constant by the second control valve 43. Therefore, the compression starting timing is advanced by turning an adjusting member 22 counterclockwise against a spring 25.
