Title: Inductance-type displacement sensor
Inventor: NAKAJIMA ATSUSHI
IPC: G01B7/00
Filed: 1989-12-29
Abstract: PURPOSE:To make it possible to measure the displacement of a body to be measured accurately by wiring coils so that the magnetic fluxes generated by the currents with carrier frequencies flowing through coils have the different polarities for every neighboring magnetic poles in concentric circle patterns. CONSTITUTION:A sensor core 10 comprises a material formed of ferromagnetic body. A circular-cylinder-shaped magnetic pole 11 and concentric-circle-shaped magnetic poles 12 and 13 are formed as a unitary body. Sensor coils 16 and 15 are provided between the magnetic poles 11 and 12 and between the magnetic poles 12 and 13, respectively. The coils 15 and 16 are connected in series and constituted so that the magnetic fluxes generated in the respective coils 15 and 16 are aligned in the reverse directions. The change in potential across a dummy coils due to the changes in inductances of the coils 15 and 16 is detected with a detecting circuit, and the displacement of a body to be measured 17 is measured. When a magnetic flux 40 from the outside is inputted into the core 10, the electromotive forces generated in the coils 15 and 16 with the magnetic flux 40 are directed in the reverse directions to each other. Thus, the electromotive forces generated with the magnetic flux 40 are offset, and the noises formed by an external magnetic fields are decreased. Therefore, the displacement of the body to be measured can be accurately measured.

IPC: H01J49/42
Filed: 1999-12-02
Abstract: PROBLEM TO BE SOLVED: To prevent generation of random noise in a mass spectrometer analyzer stage, by preventing the introduction of ions and the fresh ionization in an ion trap space from occurring. SOLUTION: Two gates are placed between the filament end cap electrodes, and positive and negative voltages are applied to these two electrodes for not letting ions and electrons enter into the ion trap space in the mass spectrometer analyzer stage. Thereby, random noise is eliminated from mass spectra, and the mass spectrometry of trace components becomes possible. The noise on chromatogram is also eliminated, and the quantitative analysis of trace components becomes available.

Title: Original scanning device
Inventor: SATO HIROSHI
IPC: G03G15/04
Filed: 1989-12-29
Abstract: PURPOSE:To make a scanning/illuminating part compact and to facilitate the adjustment of the accuracy of a reflecting mirror by providing light sources in such a manner that they are fixed by shifting the heights in a vertical direction in which an original is scanned in the vicinity of both ends of an original platen. CONSTITUTION:The device has the two-stage structure by arranging the light source 1 from the start position side and the lighting source 1' from the end position side in such a manner that they are vertically shifted from each other. A gap between the parabolic mirrors 3 and 3', which face each other, requires only such a distance that it is longer than the width of a slit arranged below the parabolic mirror. Also, since the illumination luminous flux itself can be also made reflected in an acute angle direction with respect to the incident luminous flux, the parabolic mirrors 3 and 3' can be arranged nearly perpendicu lar to an original platen glass 5. Thus, the constitution of the entire device can be made compact, and accuracy in the inclinations of parabolic mirrors 3 and 3' can be easily adjusted.
