Title: Gas spring
Inventor: WATANABE OSAMU
IPC: B60J5/10
Filed: 1978-09-05
Abstract: PURPOSE: To enable the repulsive force characteristic to be maintained always at ideal value even when the temperature varies by arranging a pressure adjusting piston which permits position adjustment from outside, in a cylinder shiftably, and permitting the pressure of high pressure gas in the cylinder to be varied.  
     CONSTITUTION: When an adjusting knob 28 is turned, a second piston rod 21 advances or retreats in the direction of axis line in a cylinder 1 through a nut 27. Accompanied by this shift, a pressure adjusting piston 20 shifts, and the high pressure gas 11 in the cylinder 1 between the pressure adjusting piston 20 and the piston 6 is compressed or expanded, and thus the internal pressure in the cylinder 1 can be adjusted freely. Accordingly, even if the outside temperature varies, the repulsive characteristic of a gas spring can be maintained always at an ideal value by turning the adjusting knob 28 from outside.

Title: Rotational speed sensor
Inventor: MATSUBARA HIRONARI
IPC: G01D5/245
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To obtain a rotational speed sensor which is compact and low-cost, by which the change amount per unit time of the number of coil interlinkage magnetic fluxes is made large and by which a large voltage can be output by a method, wherein a guidance means which protrudes to the inner wall face of a cap is installed. SOLUTION: Guidance means 38a which protrudes to the inside diameter side at equal intervals in the circumferential direction are formed at the sidewall part of a cap 38. Then, the cap 38 is fixed, together with a stay 30, a magnet 32 and a coil 24, by a resin 42 in a position in which comb teeth 36a of the stay are not facing with the means 38a. First, in a positional state that comb teeth 30a of a sensor rotor 31 do not face the means 38a, a magnetic flux which forms a magnetic route via the comb teeth 30a, 36a is circulated around the coil 34. In this case, since the gap between the comb teeth 30a, and 36a is narrow, the number of interlinkage magnetic fluxes of the coil 34 is large.  On the other hand, in a state where the comb teeth 30a do not face the comb teeth 36a, a magnetic route indicated by an arrow to the cap 38 from the means 38a is formed, and the number of interlinkage magnetic fluxes of the coil 34 is small, Consequently, the change amount of the number of interlinkage magnetic fluxes of the coil is made large, and a large induced power can be obtained even when the rotor 30 is turned at a low speed.

Filed: 1978-09-06
Abstract: PURPOSE: To economically and lightly measure the amplifying characteristics of a photoelectric conversion signal amplifier by enabling measurement of the characteristics of the amplifier by utilizing the nose generated from a photodetector.  
     CONSTITUTION: The operating current of a semiconductor laser 4 is supplied from a DC power supply 12. The light from the laser 4 is incident to a photodetector such as, for example APD8 mounted at the input terminal of a measurement amplifier 6. Since the intensity of the incident light is constant, a direct current is flown through the APD8. This current contains diffused noise. This noise is amplified by the amplifier 6 to present at the output side. When the amplified output is measured by the ordinal provess in spectrum, this spectrum represents the frequency characteristics of the amplifier 6.
