Abstract: PURPOSE:To provide the manufacture of a laminated board and a multilayer laminated board, in which water-absorption property resistance and solder heat resistance are not dispersed largely. CONSTITUTION:A laminate, in which both surfaces of a base material, in which glass cloth is impregnated with a thermosetting resin composition mainly comprising a BPA epoxy resin, a TBBPA epoxy resin, a methyltetrahydrophthalic anhydride, an epoxy vinyl ester resin and styrene and the composition is cured up to the degree of cure, where the composition is melted and fluidized at 200 deg.C, are coated with thermosetting adhesives using a BPA-TBBPA co-condensation epoxy resin and dicyandiamide as main components and the adhesives are precured up to a tack-free state at 140-160 deg.C, is employed. Copper foil and said laminates are arranged so as to be formed in copper foil/four said laminates/copper foil and heated and pressure-molded, and the thermosetting adhesives on a laminate are cured completely, thus acquiring a laminated board. Accordingly, the laminate having the same excellent water- absorption property resistance and solder heat resistance as ones at an initial stage is obtained even when a laminated-board manufacturing material preserved for a prolonged term is employed, thus acquiring products having constant quality even when the material is used at the initial stage or even after the material is preserved for the prolonged term.

Title: Recording device
Inventor: WAKAO NOBUTAKA
IPC: B41J13/00
Filed: 1985-10-08
Abstract: PURPOSE:To prevent the occurrence of choking, by a method wherein a number of pores or recessed parts are formed in a recording medium, e.g., metallic film to fill the pores with recording ink, and bubbles are produced by selective rapid heating by means of a heating element for injection. CONSTITUTION:A number of pores with a diameter of 10-200mum are formed in a film 2, serving as a recording medium, made of a metal or highly durable polyimide, and the pores are filled with recording ink 4. When a number of the pores 5 filled with the ink are moved to a thermal head 1, a voltage is selectively applied on a heating element 3 for rapid heating. In which case, bubbles are produced in the ink in the pores 5, and ink drop 6 is injected by the bubble pressure to perform recording. The recording medium 2 is held by dint of injected air sprayed from below without contaminating a recording screen, and promotes drying of a recording picture. This prevents the occurrence of choking and permits to perform high speed recording in a stable manner.

Title: Buckle
Inventor: MORI SHINJI
IPC: A44B11/26
Filed: 1998-08-07
Abstract: PROBLEM TO BE SOLVED: To provide a buckle which is high in operability in tongue plate insertion. SOLUTION: This tongue plate pushes an ejector 18 in a B1 direction, by which the engaging plate 4 of the ejector 18 is pressed to the projecting part 52 of the locking plate 20 and the locking plate 20 is turned in an A1 direction. As a result, the engaging part 50 of the locking plate 20 is inserted into the engaging hole part of the tongue plate and the latching state is attained. On the other hand, a release button 26 is pushed in an X1 direction in the latching state, by which a leg part 68 is made to press a locking pin 24 in the X1 direction and a locking spring 22 is compressed. The locking plate 20 is oscillated in an A2 direction by the elastic force generated as a result of the compression, by which the latching state is oscillated. Since the tongue plate is inserted into a diagonal direction (B direction) in the manner described above, the operability of the buckle 10 in the tongue plate insertion is improved.
