Title: Optical information recording medium
Inventor: KAMEZAKI HISAMITSU
IPC: G11B7/24
Filed: 1999-05-10
Abstract: PROBLEM TO BE SOLVED: To suppress the progress of corrosion of a metallic film by allowing a material having electron accepting property or electron donative property forming a salt on the interface between the metallic layer and a recording layer when the material is oxidized or reduced by irradiation with light to exist near the metallic layer. SOLUTION: An information recording part 3 is formed with a material having the property of an acid radical or a base in correspondence with the redox reaction of a metallic film and it is formed by filling a heat-mode recording material containing a material which absorbs light energy and converts it to heat energy or such an ionic dye material into a preformat pattern 2. When light is radiated, the redox reaction of the metallic film takes place and the film reacts with the material having electron accepting property or electron donative property disposed near the metallic film so as to assist a flow of electrons and forms a microscopically observable salt having <=10 μm, preferably <=5 μm particle diameter. This reaction proceeds slowly unlike sudden corrosion of the reflecting film caused, e.g. when water sticks.

Title: Method of containing electronic component into case
Inventor: NAKAMURA TAKESHI
IPC: H05K5/00
Filed: 1982-07-22
Abstract: PURPOSE:To facilitate the seal into a small-sized case by a method wherein two terminals are provided at the substrate part of a terminal frame, the substrate part is held between the end surfaces of thermoplastic cases, heat is generated by electric conduction between the terminals, and thus the case end surfaces are fuse-welded each other. CONSTITUTION:An oscillator 10 is spot-welded to the supporting pieces 6-1 and 6-2 for the substrate part 3 of the terminal frame 2. Each side of the substrate part 3 of the frame is fitted to the peripheral walls of the cases 20 and 22, the oscillator 10 is contained into the space formed by the recesses 21 and 23 of both the cases, and then the substrate part 3 is held between the case end surfaces 20a and 22a under a fixed pressure. When a voltage is impressed on the terminals 5-1 and 5-2 of the frame 2, the substrate part 3 generates heat by resistance, and accordingly the end surfaces 20a and 22a are fused by heating and then welded. Current does not flow through the supporting piece 6, oscillator 10, and a lead terminal 14, the oscillator 10 does not break, and then the reserve solder of the terminal 14 does not fuse and drip. This constitution enables to seal electronic components with very good efficiency without making unnecessary currernt flow into the electronic components.

Title: Filter of multilayered structure
Inventor: KATOU HARUKI
IPC: B01D39/16
Filed: 1981-08-17
Abstract: PURPOSE:To improve capturing characteristics of thin filters for dust by superposing >=2 sheets of thin filters and mechanically entangling the filters to one body. CONSTITUTION:Since superposed filters 11a, 11b are thin, fiber density and thickness are uniform, and the variance in dust collecting performance is small. If an electrostatic treatment is applied thereto by attaching a resin, the life is prolonged by the migration of the resin. The layers 14a and 12b of large electrostatic force and large capturing force are formed in the filter and 12a, 13a as prefilters are formed before said layers by the mechanical coupling by needle punching in order to form the filters into one body, whereby the double filtration of dust is accomplished. Since the layers 14a and 12b have no direct contact with the free electrons of air, they maintain the initial electrostatic force and deteriorate extremely less with time. As the filter is handled as one sheet of filter, there is no failure in mounting and the filter is easy to maintain and control.
