Filed: 1989-02-02
Abstract: PURPOSE:To enable a shaft, to which a high load is applied and which is rotated in a high speed, to be supported by interposing a sliding ring made of ceramics between a ceramic outer ring and a ceramic inner ring. CONSTITUTION:In the case where an outer ring 1, an inner ring 2, and a sliding ring 3 are made of the same ceramic material, and where factors influencing friction such as the surface roughness of sliding surfaces 2b, 3b and 3a, 1d are made to be the same condition, the sliding velocities in the respective sliding surfaces become same, and the sliding velocity becomes sufficiently small as compared with the case where the inner ring 2 and the outer ring 1 are directly slid. Further, in the case where a shaft to which only a thrust load is applied is fitted in a shaft hole 6, when the shaft is turned, the inner ring 2 is turned in the same number of revolutions as the shaft, and the load is transmitted from the neck part 2f of the taper surface 2e on the outer circumference of the inner ring 2 to the end surface 3d of the ring 3, and also sliding is caused between the neck part 2f and the end surface 3d. Then, the load is transmitted from the end surface 3c of the ring 3 to the neck part 1f of the taper surface 1e on the inner circumference of the outer ring 1, and sliding is caused between the end surface 3c and the neck part 1f.

Filed: 1996-02-08
Abstract: PROBLEM TO BE SOLVED: To shorten the distance between an inner side metallic cylinder and each connector pin by connecting the inner side metallic cylinder with an outer side metallic frame mounted onto a control electrode by a connecting metallic part. SOLUTION: A cathode support body structure 15 supporting a cathode 14 is fixed in the inside of a control electrode 8, and two heater fixing supports 1 are connected with respective connector pins 7. The cathode support body structure 15 which holds the cathode 14 by welding an outer side metallic frame 7 to the inner side of the control electrode 8, is thereby electrically connected with the control electrode 8. Next, a connecting metallic part 9 is mounted to a space between an inner side metallic cylinder 3 and the outer side metallic frame 4, and the inner side metallic cylinder 3 is electrically connected with the outer side metallic frame 4. By this constitution, the inner side metallic cylinder 3 is connected electrically with the control electrode 8 to which the lowest potential out of electrodes is applied, via the outer side metallic frame 4.  Since the inner side metallic cylinder 8 has the potential energy as low as that of the control electrode 8, the occurrence of induction potential can thereby be prevented.

Abstract: PROBLEM TO BE SOLVED: To produce a desulfurization agent for a fluidized bed type boiler having light desulfurization capability at a practical and low cost by producing a limestone type desulfurization agent whose CaO grade and fine pore volume are within respectively specified ranges. SOLUTION: Limestone with high CaO grade and having high fine pore volume is efficient as a desulfurization agent for a fluidized bed type boiler. A desulfurization agent having high desulfurization capability is therefore produced at a low cost by adjusting the CaO grade within a range of 40-56 wt.% and the volume of fine pores within a range of 20-300 mm<3> /g. Further, practicality of the agent is heightened by controlling the average particle diameter as 50 wt.% transmittance diameter within a range from 100 μm to 5 mm and the crushing strength within a range of 2-15 kg.  In order to control the particle diameter, natural porous limestone is pulverized and sieved and, at this time, the desulfurization agent is preferably produced by mixing 4-15 wt.% of cement with 85-96 wt.% of the limestone powder having the average particle diameter as 50 wt.% transmittance diameter within a range of 1.0-500 μm, adding water to the resultant powder mixture, and granulating and curing the mixture.

Title: Solid-state image pickup device
Inventor: TAKESHITA TETSUYOSHI
IPC: H01L21/52
Filed: 1986-02-06
Abstract: PURPOSE:To minimize the temperature deterioration in basic optical characteristics of a solid-state image pickup element for cutting down the cost by a method wherein a transparent sheet with thermal expansion coefficient lower than that decided by the thermal expansion coefficient of another transparent sheet whereon a photoelectric conversion element is formed and that of a transparent mounting substrate is held to be bonded between the transparent insulating sheet and the transparent mounting substrate. CONSTITUTION:A photoelectric conversion element or driving element 11 thereof is formed on a transparent insulating sheet 12 which is generally made of low expansion non-alkali glass because the driving element 11 is required of high temperature semiconductor processing as well as fine processing with the precision not exeeding micron order. Such a glass, being expensive, is hardly applicable to a transparent mounting substrate 16 in view of the larger size and resultant higher price. Therefore, the thermal stress is relieved by bonding another transparent sheet 14 with thermal expansion coefficient not exceeding 2(a+b)/3 to the space between the transparent insulating sheet 12 [with thermal expansion coefficient of (a)] whereon the photoelectric conversion element 11 is formed and the transparent mounting substrate 17 with [thermal expansion coefficient of (b)]. Through these procedures, the transparent insulating sheet 12 can be made much smaller and thinner than the transparent mounting substrate 16 at low cost. Besides, the bonding agents 13 (1) and 15 (2) can either be equivalet or different from each other.

IPC: G09G1/20
Filed: 1987-02-06
Abstract: PURPOSE:To obtain an electron beam spot focused optimally over the whole region of a fluorescent screen by applying a voltage to at least two adjacent planer electrodes so that a focusing action is made uniform in the scanning direction upon scanning and deflection of electron beams. CONSTITUTION:Electron beams 10 emitted from an electron gun initially run straight into a region put between multi-deflection plates 4 and a fluorescent screen 2, and next they are deflected toward the fluorescent screen 2 by the deflection plates to which a specified deflection voltage is applied. For example, when the specified deflection voltage is applied to two adjacent deflection plates in this case, the electron beams can be optimally focused in the first direction on the fluorescent screen simultaneously with their deflection. When the deflection voltage is changed periodically, the electron beams can be scanned by one pitch of the multi-deflection plates 4 in the first direction on the fluorescent screen. In succession when the application of the deflection voltage is exchanged one by one to the adjacent deflection electrode, scanning can be completed over the whole region of the fluorescent screen. Hence, continuously uniform and optimum focusing can be achieved even on dissimilar deflecting positions.
