Title: Curved-surface printing device
Inventor: UCHIYAMA KOICHI
IPC: B41F17/34
Filed: 1989-10-09
Abstract: PURPOSE:To make uniform an ink image supplied onto the surface of a pad by providing the pad which is brought into pressure contact with stencil base paper to be subjected to an image transfer and an elastic member which is lower than the pad in hardness and corresponding to the pad in shape through the stencil base paper and an ink layer. CONSTITUTION:When a pad 1 is brought into pressure contact with stencil base paper 14 of a printing part 10 by the pressing force of a spring, the pressure of the pad 1 is held by an elastic member 11 through the stencil base paper 14. The elastic member 11 has a hardness lower than that of the pad 1 and deformably follows the shape of the pad 1. Thus, the pressure is uniformly applied to every part of the stensil base paper 14, and a uniform image is transferred to a transfer surface 2 of the pad 1. By pressing down the pad 1 against the pressing force of the spring, the pad 1 is reversed through 180 deg. with the transfer surface 2 positioned downward, thereafter being brought into pressure contact with the surface to be printed of a work 16 to make printing thereon. Therefore, a final printing accuracy of the work 16 is also improved.

IPC: B03C3/66
Filed: 1992-09-30
Abstract: PURPOSE:To provide the electrostatic precipitation filter capable of simultaneously maintaining the electrical connection and sufficient mechanical strength with which the coupling of electric connecting terminals to a film-like electrode is sure. CONSTITUTION:This electrostatic precipitation filter is constituted by laminating a band-shaped anode electrode 1 coated with an electric insulating layer 3 consisting of a plastic film and a band-shaped cathode electrode consisting of an electrical conductive material on both sides of a metallic foil electrode layer 2 consisting of an electrical conductive material by holding these electrodes at a specified spacing thereby constituting the film-like electrode. The one flank of the electric insulating layer 3 of the laminated plastic film of the band-shaped anode electrode 1 is partly peeled to form a peeling part 6. The electric connecting terminals are coupled to the band- shaped electrode via eyelet fittings to the peeling part 6 and the non-peeling part where the electric insulating layer of the laminated plastic film is not peeled. Since the coupling of the electric connecting terminals is executed by different electrical coupling, the sure electrical connection is executed on one hand and the mechanical strength is maintained on the other. The reliability of the electrical connection is improved and the life is prolonged by both.

Title: Production by reduction diffusion method of alloy powder containing rare earth and transition metal
Inventor: ASAKAWA YOSHIYUKI
IPC: B22F9/20
Filed: 1996-09-11
Abstract: PROBLEM TO BE SOLVED: To provide a process for producing alloy products having high quality by improving the underwater collapsing property in calcined matter, thereby omitting a crushing stage and improving the yield of the products in production of a powder alloy by a reduction diffusion method. SOLUTION: Rare earth oxide powder, transition metal powder and other raw material powder are weighed and mixed. Further, a reducing agent sufficient for reducing the rare earth oxide powder is added and mixed to and with the mixture. The mixture is calcined by heating and holding the mixture up to and at the temp. at which the reducing agent melts or above and the temp. at which the desired alloy does not melt in the atmosphere where oxygen does not substantially exist, by which the rare earth oxide is reduced to a rare earth metal. The mixture is thereafter diffused into the transition metal powder to obtain the desired alloy. The calcined matter obtd. after cooling down to room temp. is charged into water to dissolve the residual reducing agent and the formed redox agent. The calcined matter is repetitively subjected to agitation and decantation and is washed. The settled alloy powder is separated and recovered and is dried. The alloy powder contg. the desired rare earth and transition metal is thus produced. The calcined matter is subjected to a hydrogen treatment after the calcination.

Abstract: PROBLEM TO BE SOLVED: To provide a portable terminal whose battery service life can be extended. SOLUTION: A standby function controller 303 controls a power source for a block oscillation circuit 305, a peripheral circuit 307 and an ALU 309 included in the portable terminal TAG. The standby function controller 303 controls the power source for the circuits 305, 307, 309 so as to select a mode where all the power sources are energized, a mode where all the power sources are de-energized or a mode where the power source of the clock oscillation circuit 305 is energized and the power sources of the other circuits are de-energized. Energizing only the clock oscillation circuit 305 and de-energizing the other circuits reduce the entire power consumption. Furthermore, a standby time up to stable oscillation required when the clock oscillation circuit is activated from an inactive state is eliminated.
