Title: Optical scanner
Inventor: TAKI KAZUYA
IPC: G02B26/10
Filed: 1995-09-28
Abstract: PROBLEM TO BE SOLVED: To provide an optical scanner capable of obtaining uniform light intensity all over the scanning area. SOLUTION: A photoresist 42 is rotatively applied on a base plate 41 so that film thickness may be larger at a peripheral part than at a center part. At such a time, the exposure sensitivity of the photoresist becomes lower at the center part than at the peripheral part. The light intensity distribution of exposing laser beams 45 and 46 is Gaussian distribution, and the light intensity gets higher nearer to the center of a laser beam. Namely, since the light intensity of interference fringe 47 becomes higher nearer to the center part, the photoresist 42 is uniformly exposed and the depth of a hologram 32 becomes uniform. Thus, uniform diffraction efficiency is obtained.

IPC: C08F8/44
Filed: 1993-10-07
Abstract: PURPOSE:To obtain an ion-cross-linked polymer improved in material properties by mixing a dispersion of fine metal compound particles with a solution of an ionic polymer to cross-link the polymer and precipitate the cross-linked polymer. CONSTITUTION:An ionic polymer is dissolved in water. NaOH is added thereto convert reactive groups into an Na salt form, because the reactive groups are less apt to ionically bond to metal compound if they remain unconverted. Fine metal compound particles are then added to the solution. The mixture is stirred to cause cross-linking of the reactive groups with the metal compound. The reaction mixture is washed with water and filtered to remove unreacted substances, and the reaction product is dried to obtain the desired polymer. This polymer has a structure formed by cross-linking the polymer with the particles. The polymer is not limited as long as it dissolves in a solvent and has reactive groups cross-linkable with the metal compound. Examples thereof include anionic polymers such as poly(acrylic acid) and poly(sulfonic acid) and cationic polymers.

Abstract: PURPOSE:To obtain durable and therefore reliable parts, by forming a step part so that the outer part of the side surface of the main body of a package is recessed from the inner part with respect to the bending direction of a lead, and avoiding the occurrence of microcracks. CONSTITUTION:A pellet 3, wires 4 and inner lead parts are packaged in a main body 1 of a package with a metal mold. A lead 2, which is extruded to the side of the package main body 1, is bent at a lead bending part 2a. At this time, the upper part of the side surface of the package main body 1 with respect to the lead 2 is made to recess inward from the lower part thereof, and a step part 1a is formed. Therefore, stress is mainly applied to a supporting point, i.e., the step part 1a. The stress is applied in the direction for compressing the lead 2 and the package main body 1, which is contacted with the lower side of the lead 2. Therefore, the stress at the time of lead bending is not applied on the upper side of the package main body 1, i.e., in the lead bending direction. Thus, micro-cracks are not yielded between the lead 2 and the resin on the lead.

Title: Material testing machine
Inventor: MATSUBA TERUO
IPC: G01N3/18
Filed: 1983-12-28
Abstract: PURPOSE:To improve the efficiency of the titled machine by interposing a load release mechanism for releasing a load of a test piece at the time of power failure, in a load system for applying the load to the test piece, so that the test piece is not influenced, even if an environment in an atmospheric chamber is varied at the time of power failure. CONSTITUTION:As for a material testing machine, when electric conduction to an electromagnetic brake 6 is cut off at the time of power failure, an operation of the brake 6 is released, and gears 4, 5 do not receive an operation of the brake 6. Therefore, even if pull rods 2H, 2L and a test piece 1 are brought to thermal contraction, no tension load is applied to the test piece 1, and no thermal stress is generated. Accordingly, after the electric conduction, the test can be executed continuously as it is with regard to its test piece 1, and a sufficient test result can be obtained. That is to say, it is unnecessary to execute a re- test newly from the beginning, and the efficiency can be improved.
