IPC: G11B21/08
Filed: 1985-09-19
Abstract: PURPOSE:To obtain an inexpensive head feeding mechanism stopping the head to a prescribed stop position accurately even when no high accuracy is called for a cam by using a sensing means to sense at which location of position information recorded on a magnetizing ring a cam position comes attended with the turning or the cam. CONSTITUTION:A sensor 11 is provided to a fixed location near the magnetizing ring 7, the sensor 11 consists of, e.g., a ferromagnetic thin film resistive element and the electric resistance of the element changes by the N/S magnetic field. When the cam 6 is driven, an output of the sensor 11 is used to detect the stop position of the cam face 8. Further, the magnetic poles N, S in the magnetizing ring 7 are magnetized with a sufficiently high accuracy with respect to + or -20mum being the accuracy of the cam face 8. It is possible to apply the magnetization in the stage that the cam 6 and the magnetizing ring 7 are assembled by using a jig in advance. Thus, the cam can be made of a plastic material and the feeding mechanism with high accuracy is formed inexpensively.

IPC: G01D5/245
Filed: 1998-07-21
Abstract: PROBLEM TO BE SOLVED: To accurately detect abnormality of a rotation angle detection device of rotating machine based on the modulation signal obtained by detecting resolver output. SOLUTION: Since modulation and cosine modulation signals taken out of the output signal of a resolver by detection fluctuate symmetrically up and down in normal time. The state this symmetry is lost is judged abnormality. For example, in the case the absolute value of the difference (region 54) between an integral value of the first half period value (curve 50) and an integral value of the latter half period value (curve 52) is larger than an abnormality judgment threshold value, abnomaly is judged because of the asymmetry of the modulation signal waveforms in the front half period and the latter half period.

IPC: G02B6/024
Filed: 1989-08-09
Abstract: PURPOSE:To attenuate one of the two intrinsic modes propagating in the polarization plane maintaining fiber to form linearly polarized light and to eliminate losses and to improve reliability by removing a part of the clad of a polarization plane maintaining fiber and loading a metallic film thereon. CONSTITUTION:A part of the clad 14 of the polarization plane maintaining fiber 11 is removed in the direction parallel with the oscillating direction of the electric field of the one intrinsic mode of the two orthogonal intrinsic modes propagating in the polarization plane maintaining fiber 11 and the metallic film 12 is provided in this removed part. The intrinsic mode in which the electric field oscillates in the direction parallel with the film plane of the metallic film 12 of such polarizer 10 made of the optical fiber does not receive the attenuation by the metallic film 12. On the other hand, the intrinsic mode in which the electric field oscillates in parallel with the film plane of the metallic film 12 is attenuated by the metallic film 12. Only the mode in which the oscillation direction of the electric field is parallel with the film plane of the metallic film 12 of the two intrinsic modes propagating in the polarization plane maintaining fiber 11 is thereby passed and, therefore, the linearly polarized light is obtd. The losses are eliminated in this way and the reliability is enhanced.

IPC: G02B5/04
Filed: 1996-07-17
Abstract: PROBLEM TO BE SOLVED: To make angle of visual field of a display narrow so that the displayed information is made visible only in a specified region by arranging a transparent light-condensing sheet having prisms as projections which make the angle of visual field narrow on front of the display. SOLUTION: On a display 1, for example, a cell 2 in 0.3mm×0.3mm size is arranged to form one dot one pixel. A transparent planer condensing sheet 3 is laminated on the front of the display. The condensing sheet 3 has lots of prisms 4 as projection on the front (light emitting face). The sideline of the prism 4 is much smaller than one dot of the cell so as to prevent irregular brightness or production of a moire pattern and to keep the display quality. The prism groups on the front of the condensing sheet 3 control the diffused light from the cells 2 of the display to a specified direction by reflection and refraction of each prism 4. Thus, the visual field is narrowed by this prism effect.

Abstract: PROBLEM TO BE SOLVED: To obtain a full color image forming device constituted so that a full color image can be inexpensively continuously formed at a high speed without deteriorating the faithful reproducibility of the full color image. SOLUTION: At the time of magnification being equal to or over the prescribed magnification, the standard exposure scanning start position and the return finish position of the first scanning action Ptn1 of an exposure scanning part are made different and the exposure scanning start position of the second and subsequent scanning actions Ptn2 is set nearer to an original than the standard exposure scanning start position. In the case that the exposure and scanning action is executed from this exposure scanning start position, it is started after it is made to stand by in a prescribed time (tWAIT) from an image forming reference signal MFGATE so that the original is started to be read by an image read gate signal IFGATE when the exposure scanning part arrives at the leading edge part of the original. Thus, the exposure scanning start position of the second and subsequent scanning actions Ptn2 can be set near to the leading edge part of the original and the original can be read at a high speed. Besides, the leading edge part of the original can be always started to be read after a fixed time (tLE) from the signal MFGATE and the full color image is continuously formed at a high speed without deteriorating the faithful reproducibility of the full color image.
