Filed: 1981-09-17
Abstract: PURPOSE:To enable measurement of a shape of an object without a probe being caught in the uneven surface of the object by means of a structure wherein a probe movable in contact with the surface of an object under measurement is raised at a certain interval and a lower peak value of the probe's locus per interval is electrically output, said peak value being magnified and recorded. CONSTITUTION:The probe 11 with its radius of about 2mm. is movable cross-wise in accordance with the shape of the object under measurement. Another probe 9 with a sharpened end is connected to a raising string 15 which is securted to an oscillator 19 via a pulley 17. By turning the eccentric axis of the oscillator 19 by means of a motor 18, the probe 9 is cyclically raised by the oscillator 19 in the vertical direction so that fine unevenness of the surface of the object can be measured without the probe being caught in the unevenness. Also, the lower peak value of the probe's locus per interval is electrically output and is magnified and recorded whereby fine variation in surface level can be scribed out.

Title: Hydraulic buffer equipped with temperature compensator
Inventor: WATANABE SHIYOUEI
IPC: F16F9/52
Filed: 1978-11-24
Abstract: PURPOSE:To obtain constant buffer effect by increasing the bolcking effect of the one-way valve depending on the temperature rise of operating oil in the mechanism in which part of operating oil is so designed as to open the one-way valve and flow through the slide of the operating piston. CONSTITUTION:When the piston rod 30 slides in the arrow-marked direction A, the spring 60 is compressed, operating oil in the chamber R flows through the slide of the operating piston 40 and gas in the gas chamber G is compressed by means of the free piston 21. When temperature of operating oil rises with a sharp slide of the piston 40, temperature-senstive agent in the chamber r is expanded by head and the spring 432 is compressed through the spring seat 433. Force applied to the valve plate 431 is on the rise, increasing the blocking force of the one-way valve 43 against the passage 402 installed on the piston 40. Thus, it becomes difficult for operating oil in the expansion process to go through the passage 402, compensating for low viscosity due to temperature rise in operating oil.

Title: Screw compression device and its rotor control device and operation control device
Inventor: FUJIWARA MITSURU
IPC: F04C29/12
Filed: 1990-06-05
Abstract: PURPOSE:To accomplish operation with good efficiency by opening a flow path opening/shutting means for jetting a low-temp. high pressure gas to a rotor when the discharge gas temp. exceeds a certain specified level, and by closing the same means for stopping the jetting of gas when the discharge gas temp. has becomes below the specified value. CONSTITUTION:A motor-driven value 17 is shut normally to hinder a low temp. gas to be passed to a working space 9. In case the discharge gas temp. is elevated abnormally, however, a temp. sensor 19 senses it, followed by judgement of the same by a controller 39, which sends an appropriate signal to the motor-driven valve 17 to open it, which should cause the low temp. gas to be jetted out of a gas jet 18 to the peripheral surface of a rotor. This causes cooling of the rotor and mixing with the high temp. gas in the working space 9, followed by re-compression and discharge to a discharge chamber 13. By mixing of the low temp. gas, the discharge air temp. will sink together with the rotor temp. This enables avoidance of abnormal thermal expansion of the rotor, and a male and a female roller 3, 2 are operated without contacting each other, so that the gap between the two rotors 2, 3 at the time of steady operation can be shrunk.

Abstract: PURPOSE: To make the contrast of interference fringes sharp by providing a light quantity attenuating means in an optical path of a reference light separated from the optical path of reflection from an object of inspection between first and second diffraction gratings so that the means can be inserted into and withdrawn from that optical path. CONSTITUTION: A light quantity attenuating plate 20 is disposed between a first diffraction grating 7 and a second diffraction grating 10 and it is made displaceable in a sliding manner between a position where it faces an optical path of a reference light and a position where it is withdrawn therefrom. On the occasion when a laser light from a laser light source 1 passes through the grating 7, diffraction of the light occurs and it is separated into a zero-order light and a plus first order diffracted light on the output side of the grating 7. While the zero-order light advances straight as the reference light, the plus first-order diffracted light is reflected by an object 9 of inspection and an object light is generated.  The quantity of the object light changes in accordance with the reflectance of the object 9 of inspection, and when the reflectance of the object 9 is high, the attenuating plate 20 is withdrawn. In the case when the object 9 of low reflectance is measured, the attenuating plate 20 is made to face the optical path of the reference light and thereby the quantity of the reference light is attenuated so that the difference in the quantity of light from the object light be lessened.
