IPC: B29C45/34
Filed: 1984-03-15
Abstract: PURPOSE:To discharge a gas in a cavity on the filling of a molten material efficiently by communicating the cavity with the outside air through a gas leakage member, which is mounted to the outer circumferential end of the cavity and consists of a porous metal. CONSTITUTION:When a mold is opened, the end surface 17a of a gas leakage member 17 composed of a porous metal and a stamper 5 are brought close at a regular interval, and a circumferential surface 17b demarcates the circumferentail surface of a cavity together with a fixing-side mold 3a and a movable-side mold 3b. When a molten material is filled, a gas in the cavity moves in the direction of an outer circumference, flows into a large number of holes in the gas leakage member 17 when the gas is compressed to some extent, and is discharged from the cavity smoothly and efficiently to the outside through a gas outflow hole 18 and a through-hole 19. Accordingly, the molten material can be filled at high speed, a cycle-up is attained, and trouble, such as cloudiness resulting from defective discharge, the sink mark of the outer circumference, etc. is eliminated.

Title: Acceleration controlling method for charged particle beams in electron microscope and similar device
Inventor: ICHINOKAWA TAKEO
IPC: H01J37/04
Filed: 1981-04-02
Abstract: PURPOSE:To enable charged particle beams to be accelerated with a very low acceleration voltage by drawing the said charged particle beams sufficiently from a charged-particle source. CONSTITUTION:The electric field between a filament 1 and a second anode 21, and the electric field between a first anode 20 and the second anode 21 effect in reverse direction.

Abstract: PROBLEM TO BE SOLVED: To efficiently use the whole of a filter by finely adjusting air volume and to maintain the eliminating performance of ozone and the filtering performance at a high level over a long time by changing the posture of a flow straightening plate according to partial differences in local air flows. SOLUTION: A filter for eliminating ozone and collecting dust 51 is incorporated in an external duct 5.

Title: Press working for lead frame
Inventor: OHASHI MASANORI
IPC: H01L23/50
Filed: 1987-03-05
Abstract: PURPOSE:To completely exclude residue, to eliminate residue-caused locking, and thereby to improve yield and increase the press operation rate, by a method wherein a high vacuum is present in a hopper only when the top force of a press is at its lower dead point. CONSTITUTION:A punch 5 of a top force 1 punches through a metal stripe 2 through a stripper 3 fixed to a die 6 of the bottom force 4, and the top force 1 arrives at its lower bottom point, when residue 7 produced in the punching process is retained in the die 6 of the bottom force 4. A rubber suction hopper 8 installed at the lower portion of the bottom force 4 is coupled with a vacuum generating unit, which realizes a momentary high vacuum only when the top force 1 is at its lower dead point. The residue 7 retained in the die 6 leaves the die 6 to be sucked into the hopper 8. The top force 1 begins to rise at a point C and reaches its upper dead point, where the vacuum is reduced to the atmospheric pressure in the hopper 8 in preparation for the next punching process. The cycle is repeated for the pressing work. Residue does not come up to damage the product, and the press is protected from stoppage due to residue lock.

Title: Compliance joint
Inventor: TAKANASHI NOBUAKI
IPC: B23P19/02
Filed: 1989-03-02
Abstract: PURPOSE:To absorb the effect of the positioning error in an axial direction between two objects so that these objects may be connected to each other by passing plural supporting rods around which springs fixed on a fixed plate is fitted, through a mobile plate and forming holes which are larger than the diameters of supporting rods but smaller than their heads in the mobile plate. CONSTITUTION:A mobile plate 1 is connected to a fixed plate 2 so that its positional posture may be changed along with that of the fixed plate 2 through springs 21 - 24 and supporting rods 11 - 14. By making the diameters of through holes 31 - 34 formed in the mobile plate 1 to pass the supporting rods 11 - 14 larger than those of the supporting rods by a fixed amount, the mobile plate 1 moves parallel and rotates in a given direction for the fixed plate 2. Since the springs 21 - 24 are arranged between the mobile plate 1 and the fixed plate 2, the mobile plate 1 comes into contact with the heads of the supporting rods under the initial condition where no weight is applied to the mobile plate 1. When an object which makes connecting action are placed, springs 21 - 24 are compressed, the object and the mobile plate 1 can rotate in forward/backward, horizontal and vertical directions and around an arbitrary axis with regard to the fixed plate 2 to absorb any positioning error between two objects by expansion and contraction, avoiding generation of excessive force.
