Title: Method and apparatus for thermoforming thermoplastic resin sheet
Inventor: FUJII JUNJI
IPC: B29C51/42
Filed: 1989-12-28
Abstract: PURPOSE:To make the efficient thermoforming of various thermoplastic resins including crystalline resin and laminated film possible by a method wherein both sides of each forming part of thermoplastic resin sheet are directly heated by being brought into contact with heating plates and, after that, the whole sheet is indirectly heated and finally the sheet is formed with a forming mold. CONSTITUTION:A direct heating zone 31 is for heating the forming part of thermoplastic resin sheet through the contact with hot plates and has a vertical pair of heating plates 32, which move vertically in time to the conveyance of the sheet. On the heating plate 32, heating surfaces 33, each of which locally and directly heats a forming part, are formed so as to jut out of the non-contact surface 34, which corresponds to the non-forming part of the sheet. An indirect heating zone 35 in the rear stage is for indirectly heating the whole sheet by utilizing far infrared heater, infrared heater, which acts on short wavelength or on medium wavelength, or the like as heat source, the temperature of which is set to the temperature answering the material and thickness of the sheet, the aimed physical properties of a formed item and the like and the upper limit temperature of which is determined by the presence and absence of the generation of drawdown. By heating both in the front stage and in the rear stage, the sheet can be heated up to the proper temperature necessary for pressure forming with a forming mold 4 under the state that the generation of drawdown, wrinkle, fusion bonding and transfer is suppressed.

Title: Printer
Inventor: NISHIDA HIDEAKI
IPC: B41J25/308
Filed: 1991-12-25
Abstract: PURPOSE:To prevent breakage of a printing medium and to perform high-speed printing by detecting the difference of relative thickness of a printing medium in the case of recognizing the position of change in thickness thereof, positioning a printing head in the initial gap regulation position and thereafter performing gap regulation, then moving a carrier in the printing direction and performing printing. CONSTITUTION:The position S1 of change in thickness of a printing medium having the difference of thickness in the printing direction is recognized and memorized by a recognition means of position of change in thickness which constitutes a CPU. Further a detection sensor 32 of difference of relative thickness detects the difference of relative thickness in the thickness of the printing medium P in the upstream part in the feed direction (direction Y) of the printing medium P from a platen 2. By the detected signal, the CPU positions the printing head 5 in the position apart from the position S1 of change in thickness at prescribed distance in the printing direction by a positioning means for gap regulation. Then gap is regulated by a gap increase and reduction means in accordance with the difference of relative thickness. Thereafter a carrier 3 is moved in the printing direction to perform printing.

Filed: 1998-12-03
Abstract: PROBLEM TO BE SOLVED: To easily design a multilayer bonding sheet superior in dimensional stability by applying a given calculation based on the product value of the linear expansion coefficient, the elastic modulus and the thickness of each of layers. SOLUTION: The linear expansion coefficient, the elastic modulus and the thickness of a material of each of layers constituting a multilayer bonding sheet are inputted from an input part 20 to a CPU 12 which calculates the product value thereof and adds the product values of the layers to obtain a sum value 1. The CPU 12 calculates the product value of the elastic modulus and the thickness of each layer, adds the product values of the layers to obtain a sum value 2, and divides the sum value 1 by the sum value 2. A combination of a base film with an adhesive layer is selected so that the sheet has a linear expansion coefficient meeting that the linear expansion coefficient difference between the sheet, and a metal foil to be overlaid is less than a value calculated according to 600/ΔT, thus forming a multilayer bonding sheet having a good dimensional stability.

Title: Production of graphite and lithium secondary cell
Inventor: KONDO JIRO
IPC: H01M4/587
Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To enable mass production of high purity graphite which is highly graphitized at a low cost lay synthesizing silicon carbide which can be easily produced as a high purity material, heating the synthesized material at high temp. to thermally dissociate silicon atoms in the silicon carbide. SOLUTION: A source material 5 essentially comprising a mixture of cake and silica is supplied to an indirect resistance heating furnace, and a carbon material 6 is disposed in the core part (C) between a pair of electrodes 3, 3 facing each other. An electric current is applied between the electrodes to produce an ingot 7 of silicon carbide around the core (C) by reduction carbonization reaction of silicon. Then successively, an electric current is applied on electrodes 3, 3 to heat the ingot 7 to a temp. higher than the sublimation temp. of silicon and below the sublimation temp. of graphite so that silicon atoms in the silicon carbide are thermally dissociated. Thus, the silicon atoms are vaporized to the outside of the ingot 7 and removed to convert the ingot 7 of silicon carbide into graphite 8 having high purity.

Title: Flywheel
Inventor: HIDAKA SHIZUAKI
IPC: F16F15/30
Filed: 1991-12-27
Abstract: PURPOSE:To reduce a difference in thermal expansion of a mass body and a ring gear by arranging a member having high heat conductivity in the diametrical directional outside part of a heat generation part of the mass body in a flywheel where the ring gear is fitted on the outer periphery of the mass body. CONSTITUTION:In the case where engagement/disengagement of a clutch is repeated frequently, frictional heat is generated in a heat generation part 10 of a mass body 4 being brought into contact with a clutch facing F, and the mass body is expanded thermally in the diametrical direction. Since a member (a) having high heat conductivity is arranged in the diametrical directional outside part from the rear of the heat generation part 10, the frictional heat is diffused swiftly to the outer periphery of the mass body 4 through the member (a). Thereby, since a ring gear 6 is expanded thermally in the diametrical direction, a difference in thermal expansion of the mass body 4 and the ring gear 6 is reduced, so that the ring gear 6 is never deformed up to a plastic deformation area due to diametrical expansive deformation. Accordingly, after the heat is removed, a fastening force of the ring gear 6 to the mass body 4 is not loosened. Since the thermal expansion of the mass body 4 is uniform, the stress is never concentrated in a bolt hole 11.

Abstract: PURPOSE:To provide an ideal shape by face-matching a held segment with an existing segment, calculating the drift quantity between the erector pivotal axis and the existing segment ring axis from the displacement quantity of the drive system of an erector, and correcting the shape information. CONSTITUTION:The existing segment ring shape Eo detected on the coordinates on the parallel plane of a swing ring 2 is converted into the existing segment shape E1 on the plane perpendicular to the existing segment axis Z**. The shape E1 is compared with the shape E2 before the existing segment is assembled, i.e., prior to a load, and each deformation trend value delta00 is obtained together with each position. Each position of the basic shape So corresponding to each position is corrected with each deformation trend value delta0 to form the new shape E3 of the next segment ring. The held segment 3h is positioned by an erector 1 based on the new shape E3. A basically ideal segment ring can be maintained, and the deformation quantity with the passage of time can be reduced.
