摘要： PROBLEM TO BE SOLVED: To provide a method for forming a conductive layer in the inside of the channel formed at an insulating film. SOLUTION: An amorphous silicon film 26A is deposited inside a channel 25 formed at a silicon oxide film 24, and a photoresist film 30 is spin-coated at the upper part of the amorphous silicon film 26A. Then the entire surface of the photoresist film 30 is irradiated with a light, so that the photoresist film 30 outside of the channel 25 is exposed. Here, a photoresist film 30 inside the channel 25 will not be exposed due to lack of exposure amount. The photoresist film 30 is developed to remove a photoresist film 30, which is outside the channel 25 being an exposure part, and then a photoresist film 30 which remains inside the channel 25 and not yet exposed is used as a mask for dry- etching to remove an amorphous silicon film 26A outside the channel 25.

CONSTITUTION:The input device housing part equipped with an upper guide and a lower guide for inserting an input device 2 while sliding it is provided on the casing forming article side face of an information processor 1. On the other hand, inside the input device housing part, a space is provided for housing a curl code and a floppy disk as well, and a drop proof counter-measure is devised against inclination in the case of carrying or moving the information processor 1 by providing a housing part cover 8 to be opened/closed on the front face. Further, the input device 2 is housed in the state of turning an input operating plane to the outside and after the input device 2 is housed, the peak point of an input operation key is recessed inside rather than the casing side face of the information processor 1. Therefore, misoperations can be prevented in the state of turning on a power source and even after the input device 2 is housed, simple input operations are enabled.

摘要： PURPOSE:To obtain an optical surveillance device for temperature and the like in concrete by using optical fiber cables and optical output measuring instruments and detecting and transmitting the signal from ferro-concrete in a containment. CONSTITUTION:A reactor containment 1 has concrete iron 1b in concrete, anti- corrosion thin tube 4 for protecting optical fiber cable, optical fiber cable 5 contained in the thin tube 4 and a measuring part 6. The cable 5 can be replaced easily for single part in case of degradation. By inputting pulses in one end of the cable 5 and measuring the Raman scattering light among reflection light at certain time later. Therefore, by laying the cable 5 spirally and densely in the concrete 1a, temperature measurement at all locations becomes possible. Also, by laying cables with anti-radiation and cables with standard specification in combination and comparing the change in light attenuation due to the radiation in operation, integral does rate in the concrete 1a can be known.

摘要： PURPOSE:To form a bent system by a relative displacement absorption structure and to remarkably decrease a design load by providing a bellows for connecting each bent pipe between a dry well of the bent pipe body and a torus. CONSTITUTION:A bent pipe bellows 9 is provided on an intermediate part of a dry well 2 of a bent pipe and a torus 3. The bent pipe bellows 9 connects the dry well 2 side of the bent pipe and the suppression torus 3 side, and on its outside periphery, a detachable bellows cover 20 is provided. Also, a bent system is not supported by the torus 3 through a support but supported by welding 27 of the bent pipe 5 and a through-part of the torus 3. In such a way, as for a nuclear reactor store container, the influence caused by a mutual relative variation of the dry well 2 and the suppression chamber torus 3/bent system is absorbed.

摘要： PURPOSE:To improve workability for mounting a bearing supporter to a stator by forming a recessed section to the molded end surface of the stator and inserting and fixing the bearing supporter with an annular protuberance for elongation around the recessed section. CONSTITUTION:A stator member 6 consisting of a stator core 4 and a stator winding 5 is molded with a resin 7, into which an inorganic powder substance or fiber is kneaded and contained, thus shaping a stator 8. An annular recessed section 9A is formed to the end face of the stator. On the other hand, a bearing supporter 12 is shaped by a steel plate and a collar section 12A and an annular protuberance 16 for elongation are formed around the bearing supporter. The bearing supporter 12 is abutted against the recessed section 9A, the protuberance 16 for elongation is pushed and the collar section 12A is pressure-welded to the inner circumferential surface of the recessed section 9A, and the bearing supporter 12 is fixed to the stator 8.

摘要： PURPOSE:To improve the astigmatism and shape of an electron beam and correctly evaluate the focus characteristic by integrally assembling an electromagnetic focusing coil together with a deflecting coil in the neck section of a projection type cathode-ray tube. CONSTITUTION:A deflecting yoke 7 is wound on an insulating bobbin 8 and inserted around the neck 4 of a projection type cathode-ray tube 1. An electromagnetic focusing coil 9 is integrally fixed by a pair of stoppers 10a, 10b at both ends in the fastening region 8a on the rear extension of the deflecting yoke 7. The neck axis of the cathode-ray tube 1 and the center axis of the coil 9 thereby coincide and have no inclination, and the precision of the coil 9 against the neck axis in the X, Y, Z axis direction is improved. The orbit of an electron beam emitted from an electron gun passes the center of the coil 9, the electron beam has no astigmatism, and the vertical and horizontal balances on a screen are improved. The evaluation of the focus characteristic thus has no dispersion, and the evaluation effect of the focus characteristic of the cathode-ray tube 1 itself is obtained.

摘要： PURPOSE:To improve accuracy in dimension, by forming holding holes, etc., at specified pitches and by inserting designated permanent magnets into a magnet base substance magnetized in the direction of thickness and into these holding holes to hold them. CONSTITUTION:A linear actuator is composed of a permanent magnet 1, an phase A pole 2 wound around with a coil 4, a phase B pole 3 wound around with a coil 5, a moving piece 6, etc. This phase A pole 2 of a stator has pole sections 21 and 22, while the phase B pole 3 of the stator has poles 31 and 32. A magnetic base substance 11 becomes the field magnet of a linear actuator, of which the whole surface is magnetized to an S-pole and the whole underside surface to an N-pole, while holding holes of specified dimension are formed in the moving direction, into which a magnetized permanent magnet 14 is inserted. Even if the permanent magnet 14 is arranged rather biasedly to a holding hole, the error is limited within the holding hole. No error is therefore accumulated, so that high pitch accuracy is obtained.
