Title: Manufacture of lead frame of semiconductor device
Inventor: SHIGA SHIYOUJI
IPC: H01L21/60
Filed: 1984-04-24
Abstract: PURPOSE:To obtain the titled lead frame of high reliability excellent economically by a method wherein the bonding parts of the leads frame are coated with necessary micro spots. CONSTITUTION:At least a kind of Au, Ag, Pd, Ni, Cu, Al or alloys of these such as Au-Ag, Ag-Pd, Pd-Ni, Al-Ni, Cu-Ni, Al-Si, Ag-In, Ag-Zn and Cu-Ag is put on the wire bonding parts of inner leads in spot form and then irradiated with laser beams into a fusion coat. From the view-point of workability, it is preferable that a fine-powder paste is dripped or injected and screen-printed to this metal. In other words, a fine powder 0.01-0.1mum in grain size produced by vapor phase reaction is the best. A high-output type such as YAG or CO2 laser is used for the laser light source. This is made to scan by condensation to a size corresponding to the metal-coated part or to about 0.1mm.phi. Since this light source yields an energy density of 10<4>-10<8>W/cm<2>, spot coating can be accomplished by fusion and quench in a short time of 1-10<-10>sec.

Title: Loop type bottom heat fine tube heat pipe
Inventor: AKACHI HISATERU
IPC: F28D15/02
Filed: 1991-01-22
Abstract: PURPOSE:To resolve two points of troubles consisting of one point that the diameter of a container is required to be increased in order to mitigate a pressure loss in operating liquid circulating power and the other point that the size of a non-return valve is increased and the reliability of the same is deteriorated since a valve body floating type non-return valve can not be used, in a separated heat receiving section and heat dissipating section type transporting device employing a loop type fine tube heat pipe equipped with the non-return valve, which effects heat transportation by the circulation of operating liquid. CONSTITUTION:The design of the present heat pipe is changed so as to apply a loop type fine tube heat pipe of heat transportation system operated by the axial vibration of operating liquid whereby a non-return valve is abolished and the increase of the size of a container is not necessitated. The structures of a heat receiving section 3 and a heat dissipating section 4 are constituted so that the operating liquid flows down naturally by the gravity of the same while a loop is constituted by connecting these two sections by two pieces of fine tubes. Further, the heat receiving section is arranged at lower level than the heat dissipating section to constitute bottom heat structure. As the result of comparing test, this separated heat receiving and heat dissipating section type heat transporting device employing the heat pipe is confirmed to have heat transporting performance, not inferior to the heat transporting device employing a loop type fine heat pipe equipped with a non-return valve which is constituted of a fine tube container, whose sectional area of pipe is two times of this type, at all.

Title: Fuel feeder
Inventor: NAGAE YOSHINORI
IPC: F02M37/00
Filed: 1984-04-24
Abstract: PURPOSE:To prevent the pressure boosted upon completion of delivery of fuel pump from functioning onto a filter by providing a check valve at the spacific position in an oil supply path while coupling between the oil supply path and the oil return path at specific position through a bypath provided with a relief valve. CONSTITUTION:The boosted pressure produced at the oil supply side upon completion of delivery of a fuel pump 11 is transmitted to an oil supply tube 6 to close a check valve 101 thus to prevent application of high pressure onto a filter 10. But, since an oil supply pump 9 is operating continuously, closing of the check valve 101 will cause boosting of pressure in an oil supply tube 5, the filter 10 and a conduit 103. Here, a relief valve 102 will open to relieve the pressure to a conduit 104 thus to suppress pressure boost. Consequently, the pressure boost in the oil supply tube 6 will damp gradually combined with flow-out to an oil return tube 7 and upon dropping below the supply pressure from an oil supply pump 9, the check valve 101 will open to supply fuel. Consequently, normal oil supply pressure is maintained to close the relief valve 102.

Title: Adjustable dot gain simulation for color proof
Inventor: ROBAATO SHII BARII
IPC: G03F3/10
Filed: 1990-03-30
Abstract: PURPOSE: To optimize exposure energy and a dot gain simulation by arranging a plate for diffusing light between a light source and a resolution board master. CONSTITUTION: Light from the light source 41 is radiated through an opening in an apparture plate 42 and passes through the optical diffusion plate 43 before reaching a photosensntive proof film 47 through a color separation master pattern 46. The diffusion plate 43 is grasped by a sliding clamp 49 fitted to a supporter 48 and can be moved up and down vertically to the optical axis of the light source 41 with the opening in the apparture plate 42 by adjusting a driving motor 52. The movement of the diffusion plate 43 in a separating direction from the light source 41 gives influence on the parallel degree of light radiating the color resolusion master 46 and the photosensitive proof film 47. Thus, the comparatively wide range of level of the printing dot gain simulation is attained concerning the photosensitive proof film 47 without changing an optimum exposure time.

Title: Production of porous membrane
Inventor: SEKIDA YOSHIYASU
IPC: B01D69/14
Filed: 1983-05-10
Abstract: PURPOSE:To obtain a porous membrane having good selectivity for permeation of molecules, a high rate of permeation and good stability, by uniformly mixing a base with an oxidizing agent, forming the mixture into a polymer membrane and oxidizing this membrane in an oxidizing atmosphere. CONSTITUTION:A base for a polymer membrane, such as cellulose acetate or polyacrylate, is dissolved in a suitable organic solvent. This solution is mixed uniformly with a solution of an oxidizing agent (e.g., permanganate or perchlorate) in an organic solvent (e.g., acetone or ethyl acetate) by means of, for example, a mixer. The resulting solution is cast on a flat plate to form a polymer membrane by a solvent casting method. When this membrane is treated in an oxidizing atmosphere (e.g., oxygen, ozone, or electron beams), the oxidizing agent uniformly dispersed in the membrane oxidizes polymer chains around its molecules, with consequent formation of pores within the membrane. In this way, the purpose porous membrane can be obtained.

Abstract: PURPOSE:To reduce moisture unevenness of a printing paper and prevent the generation of heat-creases by a method wherein, after the printing is performed on the printing paper, the whole surfaces are coated with transparent films and then the paper is dried. CONSTITUTION:The printing is performed by printing units 1-4 and then the whole surfaces of both sides of a printing paper 20 are coated with transparent films 12 by a coating unit 5. Then the printing paper 20 is transferred to a drier 6 and heated so as to vaporize a solvent of the ink and fix the colors. The temperature of the printing paper exceeds 100 deg.C by heating. However, as the whole surfaces are covered with the transparent films 12, white paper parts 7 and picture parts, where ink films 7 exist, are equally protected from moisture vaporization in a paper layer 10 so that the partial moisture content unevenness in the paper layer 10 is not produced.

Abstract: PURPOSE:To prevent burning, short shots and the like by forming grooves which are extended from the tips of arms in the direction of the center of a disk part when the main body of the type wheel is formed, and exhausting air from the grooves parts when the inserts of type parts are formed. CONSTITUTION:When the main body 4 of the type wheel is formed, the groove part 3c, which is extended from the tip part of each arm 3 in the direction of the center of the disk part 2, is formed at the same time. The air in the cavity is exhausted to free air through the groove part 3c and the air hole of a metal mold when the insert of each type part 5 is formed. Thus the burning of the type parts due to the adiabatic compression of air and the short shots are prevented.
