Patent JP-S62155532-A (JP)
Title: Formation of positioning mark for semiconductor wafer
Inventor: HONTO NOBUO
IPC: H01L21/67
Filed: 1985-12-27
Abstract: PURPOSE:To improve the precision of positioning by composing a plane reflection type diffraction grating used as a positioning mark of grooves formed in an insulating film or a polycrystalline silicon film. CONSTITUTION:An SiO2 film 3 is shaped onto a scribing line region 2 formed onto an silicon wafer 1. The SiO2 film 3 is patterned to shape a plurality of parallel grooves 4 and a plane reflection type diffraction grating is formed, and the diffraction grating is used as a positioning mark for the silicon wafer 1. Since the parallel grooves 4 as the positioning marks shaped in this manner are formed in the silicon oxide film 3 having a comparatively wide area, the effect of the grain boundary of aluminum is reduced even when an aluminum film is shaped on the surface, and the positioning marks having a superior shape remain because a step coverage is also improved. Accordingly, Al is not applied on an SiO2 film formed to a projecting shape on an silicon surface as seen in conventional devices, and the reflected beams of laser beams irradiated are hardly disturbed and detected, thus improving the precision of the detection of the positioning marks.

Filed: 1998-10-19
Abstract: PROBLEM TO BE SOLVED: To obtain an excellently printed state which is little in moire in a photomechanical process while operational efficiency of the photomechanical process is improved by making the visibility and erasure of the moire easy. SOLUTION: A screen for photomechanical process is colored by at least one color having the same property as that of a positive film 3 (for example, black color) of a dot to be applied in the case where printing is executed in the photomechanical process, or black color. When the screen 1 is used on preparation of a screen frame 6, in the case where the positive film 3 and the screen 1 are mutually superimposed on each other to expose them to a light, a shade of a screen mesh by the light L becomes easy to generate. Therefore, when the positive film 3 is transferred by rotation to the screen 1 along their superimposed surface, a moire to be generated between them becomes easy to generate.

Title: Display device for adaptive position of headphone
Inventor: MORITA YUICHI
IPC: H04R1/10
Filed: 1990-11-01
Abstract: PURPOSE:To fit a headphone to a head by adjusting the headphone to a matching position once when the headphone is fitted to the head and memorizing an indication part of a display means indicated on an indication window at that time so as to have only to adjust it that the indication part stored in advance is indicated on the display window in a succeeding usage. CONSTITUTION:In the case of using the headphone, at first a head slider 7 is elongated/contracted to be a proper length with respect to a head band 1 to fit the headphone to the head and then fine adjustment is conducted so as to allow an earphone 4 comes to an ear position. The adjustment position is kept by fitting a stopper 8 to a lock hole 7a of the head slider 7. Moreover, even when the headphone is removed from the head, the indication of the indication plate 10 indicated on the indication window 2d of the holder 2 at the fitting position adjusted at first is memorized. Thus, in the case of succeeding usage, since the head slider 7 has only to be adjusted so that the indication of the fitting position memorized in advance is indicated on the indication window 2d, no fine adjustment after the fitting to the head is not required.

Title: Fuel assembly
Inventor: IKEDA TADAHIRO
IPC: G21C3/33
Filed: 1988-11-28
Abstract: PURPOSE:To prevent a complete contraction of a expansion spring by providing an enough expansion clearance, with due consideration to an elongation difference between UO2 fuel rods and other fuel rods (MOX fuel rods) made of a mixture of plutonium oxides and a uranium dioxide (UO2). CONSTITUTION:Expansion springs 9 assembled into an upper end plug 5 of a fuel rod 2 are arranged so as to absorb an expansion of the fuel rod 2 by the contraction of the springs themselves. Though a spring 9a of a MOX fuel rod 2a has the same pitch as that of a spring 9b of a UO2 fuel rod 2b, an assembled length of the former spring is longer than the latter, and therefore in case that the fuel rod 2 expands and the spring 9 contracts, a length of a complete contraction of the spring 9a is much longer than that of the spring 9b but a contraction amount of the spring 9a can be greater than that of the spring 9b. In this way, for the spring 9a of the fuel rod 2a which would have a greater elongation than the fuel rod 2b, a more greater expansion clearance is kept and therefore a possibility to reach a complete contraction of the spring 9 can be diminished and a reliability is much improved.

Title: X-ray tube
Inventor: PEETAA SHIYARUTO
IPC: H01J35/18
Filed: 1996-11-11
Abstract: PROBLEM TO BE SOLVED: To reduce the danger of a beam emitting window being damaged by collision of back scattering electrons by holding the beam emitting window in a cathode potential, and electrically insulating it to a vacuum casing. SOLUTION: The position of a beam emitting window 23 is selected so that the angle β between the central beam ZS of an effective X-ray bundle an the normal N of a colliding surface 22 is substantially equal to an angle α. Thus, at least a substantially circular focal point more advantage for imaging of high quality is generated in the direction of the beam ZS. The window 23 is formed of a proper conductive material, and connected to a vacuum casing 1 through an insulating material 20. A cathode potential is added to the window 23, whereby back scattering electrons moved toward the window 23 are eliminated, and energy-selectively scattered. When the window 23 is circular, the electrons are scattered rotation-symmetrically. Thus, the electrons are not collided to the window 23, but collided to the area surrounding the window 23.
