Title: Gas spring
Inventor: MURATA HIROSHI
IPC: F16F9/00
Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To provide a gas spring which improves reliability and operability in assembling. SOLUTION: A circular valve body 21 which varies in its diameter due to elasticity of its own is arranged on an outer periphery of a piston 17. Before the piston 17 slid inside a cylinder 11 passes a circular groove 22, the circular valve body 21 keeps its closing position for communicating gas chambers C, D with each other. When the piston 17 passes the circular groove 22, the circular valve body 21 moves to a closing position for interrupting the communication between the gas chambers C and D. It is thus possible to extend and contract a piston rod 15 without forming a longitudinal groove for communicating the gas chambers C, D with each other inside the cylinder 11, stop the piston rod at its extended state with certainty, and thereby avoid malfunction caused by the longitudinal groove.

Title: X-ray analyzer, fine part x-ray diffracting device, fluorescent x-ray analyzer, and x-ray photoelectron analyzer
Inventor: HIRANO TATSUMI
IPC: G21K1/06
Filed: 1990-06-11
Abstract: PURPOSE:To enable a crystal structure analysis in an extremely small area by provid ing an X-ray converging mirror which is different in object point side focus position and match in image point side position behind an asymmetrical reflecting crystal spectroscope. CONSTITUTION:Incident X rays are shaped by a collimator to irradiate the asymmetri cal reflecting crystal spectroscope 2. Reflected X rays from the spectroscope 2 are projected on the spectroscope. The projection X rays are converged on the surface of a sample 4 by the X-ray mirror 3 which is arranged behind the spectroscope. Conse quently, the influence of an increase in X-ray width on a horizontal plane due to an increase in the angle of the projection X rays and a decrease in brightness can be eliminated. The intensity of diffracted X rays 5 from the sample 4 and a two-dimen sional image are measured with a photograph or by a two-dimensional X-ray detector 6 such as an imaging plate and then a structural analysis such as a crystal azimuth direction measurement is enabled by being associated with the crystal interval and phase identification in the extremely small area of the sample 4 and the driving of a sample table 7. Synchrotron radiant light is used as an X-ray light source to obtain fine X-ray flux with high intensity and optional wavelength.

Title: Reproducing video signal processing unit
Inventor: KANASHIGE SHOJI
IPC: H04N9/793
Filed: 1990-06-11
Abstract: PURPOSE:To facilitate the reproduction of a sharp video image while color masking is hardly caused by inserting a pseudo color subcarrier signal to a position equivalent to a color burst signal of a reproduced video signal without a color burst signal. CONSTITUTION:A pseudo color subcarrier signal insertion circuit 9 consists of an analog switch circuit and uses a pulse signal from a pulse signal generating circuit 7 as a timing signal to output switchingly a white black video signal for a period other than a pulse period and a pseudo color subcarrier signal from a pseudo color subcarrier signal generating circuit 11 for the pulse period switchingly. Then a color subcarrier signal is inserted and outputted to a reproduced video signal not including a color burst signal for a period equivalent to a color burst signal of the color television signal. Thus, an ACC (Automatic Color Control) circuit of a color signal processing circuit at a post-stage hardly malfunctions and the color video display device reproduces a sharp video image in which color mask hardly takes place.

Title: Control device for fuel pump
Inventor: SHIMAMURA MASAHIKO
IPC: F02M37/08
Filed: 1982-08-31
Abstract: PURPOSE:To maintain drive voltage of a fuel pump in constant by controllably varying, in response to the variation of supply voltage, the terminal voltage across a capacitor of a motor fuel pump connected to a power supply through the capacitor in series. CONSTITUTION:When supply voltage Vb of an alternator or the like is varied, for example, boosted, the corresponding reference voltage V0 of a reference voltage setting circuit D obtained from the potential dividing ratio is also boosted. As a result, the output of a comparator A1 becomes ''L'' to increase OFF time of a transistor T5 and the charge amount of a capacitor C2 so that the terminal voltage is boosted by the boosting of the reference voltage. Also, when Vb is lowered, the reference voltage V0 is lowered and accordingly the output of the comparator A1 becomes ''H'' so that the terminal voltage of the capacitor C2 is also lowered by the fall of the reference voltage V0. Thus, the drive voltage of a fuel pump can be maintained in constant.

Title: Optical system for dichroic copying device
Inventor: KAJIWARA NORIO
IPC: G03G15/04
Filed: 1983-08-19
Abstract: PURPOSE:To set an enlargement and a reduction rate large without increasing the size of a device, and also to reduce the scattering and falling of a developer by making an exposure scan so that the 3rd mirror of an exposure scanning optical system approaches an image-forming lens. CONSTITUTION:The 1st-the 3rd mirros 3-5 run from left to right to make an exposure scan. When an enlarged copy is taken, original scan distance is shorter than in life-size copying operation. Even when a lens 6 moves to a position 6' during enlargement copying operation, the current scan distance of the 3rd mirror 5 is short, so the 3rd mirror 5 and a lens 6' do not interfere with each other. Therefore, the enlargement rate is made larger than that of a conventional system which scans the 3rd mirror 5 away from the lens 6. Further, developing devices 21 and 35 can be arranged right upper photosensitive drums 11 and 12, so the reduction rate is also made larger, which is advantageous to a problem such as the falling and scattering of the developer.

Filed: 1985-07-08
Abstract: PURPOSE:To effect non-contacting film thickness measurement unaffected by magnetic characteristic of the specimen thickness, by detecting rotation of a polarized wave front caused by the Faraday effect at the time when a beam of linearly polarized light through the specimen film residual magnetism. CONSTITUTION:A beam of light of source 3 is subjected to linear polarization with a light polarizer 4 for transmission through a magnetic tape 1. At this moment, as the coated film 1b of the tape 1 is under effect of constant alternating magnetic field with a magnetizing apparatus 2, the residual magnetism causing the Faraday effect allows rotation of the polarized wave front of the linearly polarized light to be rotated. Accordingly, determination of this rotation angle leads to measurement of thickness of the film 1b. Here, after photoelectric conversion by a light receiver 6, AC element and mean value are determined by AC amplifier 8 and integrator 7 and dividing process is given by a divider 9 for compensation of fluctuations of the source 3, etc. and the rotation angle is determined for thickness of the film 1b. Later the tape 1 is demagnetized by a demagnetizer 10.
