Title: Unfired ceramic sheet
Inventor: NAKAO KEIICHI
IPC: H01G13/00
Filed: 1987-09-07
Abstract: PURPOSE:To prevent a solvent contained in an electrode ink from permeating into an unfired ceramic sheet by a method wherein the ceramic raw sheet is composed of a polymer resin and metallic oxide powder. CONSTITUTION:An unfired ceramic sheet is composed of a polymer resin and metallic oxide powder. Due to said composition of the unfired ceramic sheet, the unfavorable effect of the solvent contained in evaporation drying ink on the unfired sheet even in an unfired ceramic sheet of extremely thin film thickness can be averted by using the polymer resin as a vehicle in a slurry. Thus, the title unfired ceramic sheet conventionally unable to be laminated due to the permeation of the electrode ink can be manufactured enabling a thin filmed dielectric layer to be formed.

IPC: H01S5/343
Filed: 1994-09-19
Abstract: PURPOSE:To obtain an optical waveguide element having a structure with which the refractive index differences are settable with good reproducibility and controllability by adopting the structure in which second layers are cut along 'a' light propagation paths and a material having the refractive index lower than the refractive index of either of the first layers and the second layer is embedded.

The distribution of the effective refractive indices within the layer structure including the active layers 4 is set and a guide layer 6 is formed as the second layer to define the propagation path of light within the layer structure. The guide layer 6 has the shape cut along the optical waveguide part 44, i.e., the shape where the part corresponding to the periphery of the optical waveguide part 44 is removed. A block layer 5 and a clad layer 7 are formed, out of materials having the equal refractive index. The guide layer 6 is embedded by these two layers 5, 7. The layers having the refractive indices lower than the refractive indices of the active layers 4 and the guide layer 6 are selected as the refractive indices of the block layer 5 and the clad layer 7.

Title: Die spring device
Inventor: UMETSU CHIHARU
IPC: F16F9/088
Filed: 1989-08-30
Abstract: PURPOSE:To prevent action of excessive lateral load and to enhance durability by arranging a bearing for supporting the lateral load applied in the radial direction of a rod in the inner circumferential part of a through hole for the rod and making the rod tiltable to the axis of a hausing taking the bearing as the supporting point. CONSTITUTION:At the time of tilting the axis Xc of a die spring device 10 to a supporting part 97, the supporting part 97 contacts with the load receiving part 46. Therefore, the load is loaded on the axis of rod 12. In the case of pushing the rod 12 in a cylinder 11 by descending the supporting part 97 under this condition by distance of the stroke S, the load receiving part 46 is straightly descended to the direction, where the supporting part 97 descends, and the axis X1 of rod 12 is tilted by theta2 angle to the axis X0 of cylinder 11 under making the bearing 90 the supporting point. That is, even if the rod 12 displaces by the stroke S, the load receiving part 46 is not displaced in the side direction. Therefore, the friction force between the load receiving part 46 and the supporting part 97, is not generated and the excess side load is not generated to the rod 12.

Title: Method for cleaning molten steel in tundish
Inventor: SASAI KATSUHIRO
IPC: B22D11/116
Filed: 1993-08-18
Abstract: PURPOSE:To improve the quality of a cast slab by supplying an easily meltable heat insulating agent into a tundish and also, adding Ca base flux. CONSTITUTION:The easily meltable heat insulating agent 2 is beforehand charged into the tundish 1. At the time of starting the pouring of molten steel 3, CaO based flux-containing wire 6 is added near the pouring point of molten steel in the tundish 1 from a ladle 4 by using a wire addition device 5. The addition of the CaO based flux accelerates flocculation and aggregation of non-metallic inclusions, and the floating-up and separating speed is quickened. Further, at the time of using the easily meltable heat insulating agent 2 in which the liquid-phase is caused below the molten steel temp., the non-metallic inclusion absorptivity is improved, the ultimate concn. of non-metallic inclusion is lowered. By this method, the contamination of the molten steel at the initial stage of the casting is quickly reduced and further, the removal effect of the non-metallic inclusion in the tundish can be improved.

IPC: H01M50/528
Filed: 1998-08-07
Abstract: PROBLEM TO BE SOLVED: To improve collection efficiency and contact reliability at a welding place. SOLUTION: A collector body 31 of a negative electrode collector is welded at the bottom surface of an electrode body 15, a lead piece 34 is formed by extending it from the outer peripheral edge of the collector body and folding it, and a contact portion 36 of the lead piece 34 is welded on the bottom 13 of a case 11. This welding uses a spot welding electrode 40, in which the tip of a circular-bar-shaped electrode body 41 is provided for a position decentened from the axial center, and this position is a welding portion 42.
