Title: Pressure measuring device for high temperature fluid
Inventor: ISHIZAKA TAKAO
IPC: G01L19/00
Filed: 1981-06-05
Abstract: PURPOSE:To obtain the pressure measuring device for high temperature fluid, which has no trouble on sealing effect and is inexpensive, by providing a structure wherein a packing is pushed to a ceramic inner tube by a coned disc spring through a sleeve. CONSTITUTION:The packing 11 is pushed to the ceramic inner tube 8 by the coned disc spring 15 through the sleeve 12. Said pushing force is imparted by a tightening bolt 13 which is screwed into a threaded boss 17 welded to a reinforcing ring 16. Therefore the gap is not formed in the sealed surface due to the difference in thermal expansion of the ceramic inner tube 8 and the reinforcing ring 16 in the radial direction at the time of high temperature. Therefore zircaloy is not required for the reinforcing ring 16, but stainless steel is used. Therefore the price becomes inexpensive to the large extent. Stainless steel is also used for the boss 17. Thus the inexpensive pressure measuring device having excellent machining property for the high temperature fluid can be obtained.

Title: Solid-state image sensing element
Inventor: YAGI HIROFUMI
IPC: H04N5/359
Filed: 1989-04-04
Abstract: PURPOSE:To improve an image sensing element of this design in photoelectric conversion efficiency by a method wherein the reflected light by a reflective means is concentrated on a corresponding photoelectric conversion layer through a condensing means. CONSTITUTION:Infrared light incident on a rear-incident type infrared solid-state image sensing element is not absorbed by a photoelectric conversion layer 2 but penetrates through it. Light reflected by an optically reflective aluiminum film 12 is reflected again by the inner wall of the film 12 which forms a condensing means to be incident again on the corresponding layer 2 as being concentrated. On the other hand, adventitious infrared light is reflected by the outer wall of the film 12 and prevented from being incident on the layer 2. By this setup, not only crosstalk can be prevented but also a solid-state image sensing element can be improved in photoelectric conversion efficiency.

Title: Processing method for electrode terminal
Inventor: MIYAKE YASUAKI
IPC: G02F1/1343
Filed: 1994-04-25
Abstract: PURPOSE:To reduce the whole of processing stages by removing short-circuit electrodes by laser beam machining to minimize the stage of machining and omitting the washing stage. CONSTITUTION:With respect to a liquid crystal display device D obtained from a large-area liquid crystal panel by division, an edge 25 of a glass plate G2 where a short-circuit electrode 22 is formed is chamfered by grinding. Since a glass end face 24 is accurately broken differently from break of an ear part having a narrow width, grinding of the glass end face 24 and a corner 26 is unnecessary and it is sufficient if only the edge 25 is ground, and dry grinding can be adopted. Thereafter, an area (q) on the outside (the side including the short-circuit electrode 22) of a line 23 traversing the end parts of electrode terminals 21 is irradiated with ArF laser. Thus, only the electrode 22 on the area (q) is removed by the decomposition and peeling action obtained by excimer laser irradiation.
