Title: Strength testing method for poppet valve
Inventor: NAKAJIMA KEIICHI
IPC: G01N3/20
Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To make it possible to verify the strength of the vicinity of the root of a valve head, which is the high-stress generating part, by rotating a rotary shaft and a poppet valve, and applying a bending load on a valve stem end in the right-angle direction to the revolving shaft center. SOLUTION: A rotary shaft 1, to which a rotary gear 6 is fixed, is rotated by the turning torque of a driving motor, which is transmitted through a worm. A mushroom-shaped valve 3, which is fixed to the rotary shaft 1 with a suppressing metal piece 2 and a bolt 4, is rotated. In the meantime, to a valve- shaft end 38, which is the free end of the valve 3, the gravity of a weight 13 acts downward through a suspending lanyard 14, a load jig 12 and a load bearing 10. Thus, the valve 3, whose one end is fixed to the rotary shaft 1, acts as the cantilever, which receives the bending load (load) on the valve shaft end 38 in rotation. In this case, the axial-direction distribution of the load stress (bending stress) of the valve 3 becomes the stress distribution, wherein the maximum stress is generated in the vicinity of the curved surface part or the shade root.  Therefore, the maximum load can be applied at the vicinity of the shade root part, and the strength verification can be performed.

Title: Rotary compressor
Inventor: NAKAMURA KEIICHI
IPC: F01C21/08
Filed: 1981-11-20
Abstract: PURPOSE:To raise the efficiency of a compressor by connecting a piston to the end part of a slide vane and keeping the contact pressure of the slide vane onto a rotor at the minimum necessary constant level, while pressurizing said piston with a fluid. CONSTITUTION:An auxiliary cylinder 22 is formed on a main cylinder 11 via a through hole 21 connected to an internal chamber 12, and into this through hole 21 a slide vane 25 is airtightly and slidably inserted. In the upper part of the upper chamber 27 of the auxiliary cylinder 22, a pressure suppling hole 29 for suppling prescribed pressure is made. The slide vane 25 vertically reciprocates at every rotation of a rotor 20, while pressure in the auxiliary valve 22 keeps a constant level irrespective of the position of the slide vane 25. For this reason, a constant pressure is always applied to the pressure receiving surface of the piston 26, so that it is possible to always keep the contact pressure of the slide vane 25 onto the rotor 20 at a constant level enabling the efficiency of a compressor to be improved.

Title: Optical fiber gyro
Inventor: ONO KOUZOU
IPC: G01C19/00
Filed: 1983-10-04
Abstract: PURPOSE:To hold such degree of modulation that an optical fiber gyro obtains always a high sensitivity by adjusting a voltage impressed to a phase modulation in the feedback system so that DC components in the output of a photodetector are a certain value. CONSTITUTION:Before exit lights from an optical fiber loop 5 are synthesized by a half mirror 2, they are separated by half mirrors 7 and 8 and have intensities detected by photodetectors 9 and 10. Outputs of photodetectors 9 and 10 are added by an adder 13, and the result is allowed to pass a 1/4 attenuator 14. The output of this attenuator 14 and the value obtained by taking out only DC components in an LPF12 are compared with each other by a comparator 15. If the output of the LPF12 is equal to the output of the attenuator 14, degradation of the output is about 10% in comparison with the use with a maximum value and is dependent upon a modulation degree (b) and an oscillation frequency phi. Since the phase modulator using a piezoelectric oscillator is used with a resonance frequency, the frequency phi is fixed and the modulation degree (b) is changed to obtain 2bsinphi/2approx.=2.5. Thus, fluctuation of a scale factor due to variation of the degree of modulation of the phase modulator is suppressed to obtain a high-precision optical fiber gyro.
