Title: Resin mold apparatus
Inventor: KIYOHARA TOSHINORI
IPC: B29C45/02
Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To easily separate an unnecessary resin by charging resin tablets into a pot and holding a lead frame between cavities to fit respective molds with each other and fluidizing the resin tablets pressurized by a plunger before injecting them into the cavities. SOLUTION: Resin tablets 32 are charched into the pot 24 of a lower mold 23 and lower and middle molds 23, 25 are closed to place a lead frame 34 on a cavity 27 and an upper mold 29 is fitted to the molds 23, 25. After mold clamping is completed, a plunger 31 is operated to pressurize and fluidize the resin tablets 32. The molten resin accumulated in the cavity 27 flows in the cavity 27 from a through-hole 28 to compress the air in the cavity to discharge the same to the outside of the molds but the sudden inflow of the resin is prevented by this pressure and the resin is successively injected by the pressure of the plunger 31. Thereafter, the molds are opened in a semi-cured state. The resin is constricted between the through-hole 28 and the cavity and the unnecessary resin communicating with a cull part 26 can be easily cut.

Title: Hologram scanner
Inventor: YAMAGISHI FUMIO
IPC: G02B26/10
Filed: 1987-09-08
Abstract: PURPOSE:To prevent the generation of the dislocation of a scanning beam, which follows up the deviation in the course of rotation of the surface of a disk, by equalizing a shift in the emitting direction of the beam, and a shift of the incident point, caused by the rotational deviation and the flapping of a hologram disk, respectively. CONSTITUTION:A distance extending from the rotational center of a hologram disk 15 at the time of bringing a laser beam to deflection scan by a rotation of the disk 15, to an incident position P of the laser beam to the disk 15, an incident angle, an emission angle, and a distance extending from the laser beam incident point P on the disk 15 to the scanning surface 17 are denoted as R, thetai, thetao, and L, respectively. In this case, a relation of (1 - costhetai/costhetao) L = {thetai+thetao)/costhetai} R is satisfied. The left side of this expression shows the degree of a shift in the emitting direction of a beam, which follow up the rotational deflection of the disk 15, the right side shows the degree of a shift which follows up the up-and-down motion of the incident point P due to the gate of the disk 15, and by equalizing them, both shifts are offset and the dislocation of the beam is not generated.

Title: Manufacture of semiconductor element
Inventor: TSUBOTA TAKASHI
IPC: H01L21/208
Filed: 1987-09-08
Abstract: PURPOSE:To obtain crystal growth surface completed by eliminating the grown melt as a surface for emitting light as LED by making the band gap energy of crystal layer which grows after formation of p-n junction larger than that of p-n junction position. CONSTITUTION:The conductivity type of crystal growth layer changes from n to p at 875 deg.C when the n-type GaAs single crystal substrate is brought into contact with the melt obtained by adding GaAs, Al, and Si to Ga at 930 deg.C and is cooled at a rate of 0.5 deg.C per minute. At this point if Al is added without separating the substrate, a crystal with Al mol fraction XAl which is larger than that in growing crystal on inversion begins to grow newly. Thus, after then n, p inversion, a crystal growth layer with even larger band gap energy can be obtained. For example, the Si dope AlGaAs LED can be completed by forming n and p-type electrode by separation when a growth surface layer of XAl1=0.1 is formed.

Abstract: PROBLEM TO BE SOLVED: To improve hygroscopicity and deodorization functions by superposing air permeable and flexible outside layer materials to form plural closed spaces and housing inside layer materials formed by juxtaposing bags sealed with charcoal grains into these spaces. SOLUTION: Thin-film layers 3 consisting of non-woven fabrics having good slipperiness are formed on the inside surfaces of cushion materials 2 formed on the inside surfaces of mat fabrics 1. A pair of the mat fabrics 1, cushion materials 2 and thin-film layers 3 integrally subjected to quilting are disposed to face each other and the closed space parts 14 segmented to a rectangular shape in the transverse direction of the mat fabrics 1 are formed by seams 4 sewn at specified intervals. The inside layer materials 5 juxtaposed with the bags sealed therein with the charcoal grains C are respectively inserted into the space parts 14 and peripheral edges are sewn. Since the structure obtd. by inserting the inside layer materials 5 respectively into the plural independently formed space parts 14 is adopted, the inside layer materials 5 are evenly dispersed and arranged over the entire part of the mat. The gathering of the inside layer materials 5 at one point or the deviating of the inside layer materials is thus averted even if the mat receives strong vibration or is moved.

Atomized particles blown from the atomizing nozzle, after being expanded at low pressure, flow with a given inertia force toward the head. Part of atomized particles are sucked by the fine particle collectors through the particle outflow ports. The sucked atomized particles are simultaneously submitted to classification by inertia and expansion at low pressure simultaneously. On the other hand, coarse particles with larger inertia force are not sucked but collected by a coarse particle collector.
