IPC: H04N9/07
Filed: 1990-07-16
Abstract: PURPOSE:To improve reading efficiency without lowering resolution by comprising a diffraction grating so as to curve in a direction of angle of field centering the principal point of a lens. CONSTITUTION:The diffraction grating 5 is comprised so as to curve in the direction of angle of field centering the principal point of the lens 2. In other words, the diffraction grating provided with cylindrical shape curved surface so as to plot a circular arc in accordance with the angle of field centering the principal point of the lens 2 is used. Therefore, light can be made incident on the diffraction grating almost at right angles in spite of the angle of field. Thereby, an angle of diffraction can be kept constant in spite of the angle of field. Therefore, no change occurs in the angle of diffraction by the angle of field. Thereby, color-separated diffracted light can be image-formed on a CCD 4 as three parallel rays. As a result, the position of the color-separated diffracted light almost coincides with that of each photodetector string of R, G, and B. Therefore, it is possible to prevent the resolution lowering and to improve the reading efficiency.

Title: Turbine blade
Inventor: TSURUKI MASAKI
IPC: F02C7/00
Filed: 1997-07-14
Abstract: PROBLEM TO BE SOLVED: To reduce the thermal stress generated on a section in parallel with a code direction in addition to the stress in a span direction, and to improve the material allowable value, by allowing three orthogonal crystalline axes to coincide with the directions of three main stress respectively within a specific value in an area where the maximum stress is generated. SOLUTION: Since a monocrystalline heat-proof alloy has a cubic system, it has three orthogonal crystalline axes. The directions of three crystalline axes are represented by the vectors <100>, <010>, <001>. A z-axis direction is allowed to coincide with <001>. The other two axes are in parallel with a code direction. The relationship between two axes and a blade section 2 in the code direction has eight symmetry axes in phase, because two axes are exchangeable. All phase relationship can be represented by the phase relationship of 0 deg.-45 deg. when the initial position relationship is 0 deg.. Further on a position where the maximum stress of a component in the code direction, of the generated stress, is generated, a direction of the vertical stress is allowed to coincide with one of three transverse crystalline axes within ±5 deg. in maximum.

Abstract: PURPOSE:To remove mutual interference when a plurality of photoelectric switches are aligned and fixed in one line by magnetically transmitting a synchronous timing signal efficiently from a front stage to a rear stage, and shifting the sensing light of each photoelectric switch. CONSTITUTION:Photoelectric switches 7a and 7b are aligned and fixed in one line with an attaching member 8. Transmitting coils 3a and 3b and receiving coils 2a and 2b of the photoelectric switches 7a and 7b are aligned on the same axis 6 which is in parallel with the aligning direction of the photoelectric switches 7a and 7b. Thus, the transmitting coil 3b and the receiving coil 2a accurately face in the close proximity. Since the magnetic coupling between the coils 3b and 2a becomes tight, the magnetic signal based on the synchronous timing signal is generated in the transmitting coil 3b and positively received with the receiving coil 2a.
