Title: Production of laminated sheet
Inventor: FUKUMOTO YASUFUMI
IPC: B29C70/06
Filed: 1989-02-15
Abstract: PURPOSE:To sufficiently cure a resin and to prevent the contraction of excessive resin and to enhance roughness of the surface by superposing necessary sheets of prepreg to form a laminated body and providing metallic foils on the top surface and/or the rear surface thereof and integrating the laminated body and the metallic foils at the specified temp. CONSTITUTION:The whole thermosetting resin can be utilized for a prepreg but epoxy resin is preferably utilized. As the base material of the prepreg, woven fabric, nonwoven fabric and a mat made of inorganic fiber, organic synthetic fiber and natural fiber or paper or combination thereof are utilized. Amount of resin for impregnating the base material is preferably regulated to 40-60wt.% as amount of resin after drying. As metallic foil, simple substance such as copper, aluminum, nickel, zinc and iron having 18-105mum thickness, alloy and composite foil are utilized. In accordance with necessity, chemical and physical treatment is performed on single side or double sides and furthermore the layer of an adhesive can be provided on single side. It is necessary that the temp. at a time for lamination and molding is made 5-30 deg.C higher than glass transition temp. of resin for the prepreg. When the temp. is less than 5 deg.C, curing and integration of resin are made insufficient. When the temp. exceeds 30 deg.C, contraction of resin is made large.

Title: Thermal head
Inventor: SHIRAKAWA KYOJI
IPC: B41J2/335
Filed: 1986-02-21
Abstract: PURPOSE:To obtain the good printing by contacting the pointed tip of a thermal resistor layer with a thermal recording paper under pressure, by exposing a zigzagly the thermal resistor layer over from the crest part of a glaze layer on an individual lead electrode side to the step part thereof. CONSTITUTION:The upper face 12a of a glaze layer 12A of a common electrode 4A side is formed below the upper face 12b of a glaze layer 12B on an individual lead electrode 4B side via the step part 12c formed near the crest part of the glaze layer 12. Then, a thermal resistor layer 3 is zigzagly exposed over from the crest part of the glaze layer 12B on the individual lead electrode 4B side to the step part 12c thereof. A thermal head is contacted with a thermal recording paper P under pressure by an inclination angle of theta deg.. Then, because the heat conduction to the thermal recording paper P is carried out by the pointed tip 3b of the thermal resistor layer 3 protruded toward the thermal recording paper P rather than toward the common electrode 4A and the individual lead electrode 4B, the quality of printing is remarkably improved. Further, because the pointed tip 3b is protruded by an almost triangular section and well covered by a protective layer 7, its service duration becomes longer.

Title: Manufacture of double metallic pipe
Inventor: KODERA SHUNEI
IPC: B23K20/04
Filed: 1990-02-20
Abstract: PURPOSE:To provide the products without the structural defect and to enlarge the range of possibility of manufacture by fitting the high alloy hollow billet in the hollow billet of carbon steel, etc., and then, seal-welding the boundary end, heating it, diffusion-joining the boundary surface, and then executing cross helical rolling. CONSTITUTION:The stripping of the double metallic pipe during rolling or the deviation of the inner and outer pipes is properly prevented by increasing the shearing strength of the boundary part of inner and outer pipes on the double billet before rolling. This shearing strength is properly obtained by diffusion-joining the boundary surface after seal-welding the boundary end. The prescribed temperature range is desirable as the heating temperature for diffusion-joining. Because the nitrogen gas being residual in the clearance is absorbed into the inner and outer steel pipe with heating for the diffusion-joining by introducing an inert atmosphere of the nitrogen atmosphere, etc., or the vacuum state for the operation of seal-welding, the shearing strength can be increased. Therefore, the products without the jointed deflect is provided and the mass-production can be performed.
