Title: Engaging tool
Inventor: MORITA TAMAO
IPC: H01F7/02
Filed: 1986-12-05
Abstract: PURPOSE:To allow an engaging tool from being scarcely removed without altering an external appearance by providing a hole of specific shape in a nonmagnetic case for engaging a permanent magnet and a ferromagnetic plate. CONSTITUTION:Since opposed both side parts 4b, 4b of one side of the hole edge 4b of a case 4 are long, even if a leverlike force is acted at one end of the attracting surface of a ferromagnetic plate 3 of this direction at the other end as a fulcrum, the outer periphery of a ferromagnetic projection 3a abut on the one long part 4b of the edge 4b, and the projection cannot incline. Accordingly, since the plate 3 is not raised, the projection 3a is not removed. When similar force is applied to the one ends of the short parts 4b, 4b of the edge 4b at the attracting surface of the plate 3 in the opposing direction, the projection 3a does not touch the edge 4b since the part 4b of the edge 4b of this direction is short, and it can freely incline. Thus, the plate 3 is readily raised, the projection 3a is removed to disengage the engagement.

Abstract: PURPOSE:To eliminate the need for intricate working and to reduce cost by inclining and disposing a flat plate-shaped magneto-optic crystal body with respect to the axial center of the cylindrical hole of a permanent magnet. CONSTITUTION:The permanent magnet 4 of a cylindrical shape having the cylindrical hole 3 at the center is disposed between polarizers 1 and 2 disposed in such a manner that the polarization directions vary by 45 deg. from each other.

Title: Air permeable compression molding and its production
Inventor: YOSHIKAWA KIMIYOSHI
IPC: B60R21/26
Filed: 1993-11-19
Abstract: PURPOSE:To improve dimensional accuracy after compression molding without impairing the intrinsic corrosion resistance and heat resistance of stainless steel wires by specifying the hardening coefft. and resetting rate of the stainless steel wire and the variation in the size thereof at the time of laminating, compressing and molding bent wires consisting of the stainless steel wires. CONSTITUTION:The elasticity resetting rate of the compression molding 11 is required to be suppressed by relieving the work hardening of strands which are blanks in order to suppress the resetting of the molding 11. The product of a work hardening index (n) and an yield stress Ys is defined as the hardening coefft. nxYs as an index to show the degree of work hardening. The compression molding having good shape holdability and high dimensional accuracy is obtd. if the materials having the curing coefft. of <=15% are used and are molded. On the other hand, the relation between the resetting rate and the variation delta/X of the compression molding is such that the variation in the size increases sharply from about the point where the resetting exceeds 20. The resetting rate at which the materials are compression molded is, thereupon, confined to <=15% and the variation in the size to delta/X<=0.006. In the equation, delta is a standard deviation and * is the average value of the thickness after molding.

Abstract: PURPOSE:To prevent the erosion and the exfoliation of an electrode at the time of etching for eliminating the strain of a dicing surface, by covering the electrode with a layer of material which is not eroded by etching liquid. CONSTITUTION:A P-type electrode 23 is formed on the lower surface of an element main body constituted of P-type compound semiconductor 21 and N-type compound semiconductor 22.

IPC: B41J11/48
Filed: 1989-11-08
Abstract: PURPOSE:To make smooth inserting/removing of various types of removable media, which are inserted/removed in the horizontal direction, possible by a method wherein at a position where separate recording papers mutually pass by, an auxiliary paper guide which is turnable by a specific angle, to the front and back, in the same direction as inserting/removing direction of recording papers is equipped. CONSTITUTION:When a removable medium 4 is inserted in A direction, an auxiliary paper guide 3 turns by 90 deg. or more in C direction with a support point B as its support, and therefore, the removable medium 4 can be easily inserted. When the removable medium 4 is polled out, the auxiliary paper guide 3 once falls in a space E by its own weight, and the auxiliary paper guide 3 crosses with an ink ribbon 4-a and turns by 90 deg. or more in C' direction with the support point B as its center. For this reason, the removable medium 4 can be smoothly pulled out without generating trouble such as hang-up, etc. Thus, the l turnable range for the auxiliary paper guide 3 becomes 180 deg. or more when the front angle and rear angle are joined, and therefore, a removable medium which is inserted/removed in the horizontal direction can be smoothly inserted/removed.
