Title: Manufacture of polyimide cover lay film
Inventor: SUGITANI ATSUSHI
IPC: H05K3/28
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To manufacture a cover lay film for a flexible printed circuit board with small curl and good adhesion by heating or dampening a mold releasing material just before stacking the mold releasing material, thereby adjusting the moisture content of the mold releasing material within the specified range. SOLUTION: A thermosetting adhesive such as epoxy resin, phenol butyral resin, epoxy-NBR resin, or the like is applied by a roll coater on one side of a polyimide film just before stacking a mold releasing material, and a solvent is evaporated and removed at 50-150 deg.C by an in-line drier so as to half harden the thermosetting adhesive, and then the mold releasing material where the moisture content is adjusted to 2-4wt.% by a heated roll is stacked. Hereby, a cover lay film for a printed circuit board with small curl and good adhesion can be manufactured, and the productivity and yield can be improved.

Title: Device for separating non-magnetic metal from solid mixture
Inventor: YURUKU YUURIUSU
IPC: B03C1/24
Filed: 1990-02-28
Abstract: PURPOSE: To provide an apparatus with a simple structure capable of effectively separating non-ferrous metals from a solid mixture by arranging a magnetic field generator alongside a straight and (or) curved or bent slideway consisting of a material of proof electrical conductivity. CONSTITUTION: A magnetic rotor 15 to be adopted as the magnetic field generator is borne in an oscillation section alongside the slideway 4 consisting of the material of the poor electrical conductivity below a conveyor belt 2. The expression 'poor electrical conductivity' takes the fact that all materials have electrical conductivity into consideration. The conductivity of the material of the poor electrical conductivity is substantially zero. The mixture transported to a throwing-down zone 26 largely beyond a perpendicular line 23 by the conveyor belt 2 enters the inside of a parabola 27. The entire magnetic force of eddy current acts on the material throwing-down zone 26 existing on a working line 28 corresponding to the optimum effect of a magnetic rotor 15 and, therefore, the non-ferrous metals deflected in correspondence to the parabola 27 fall into a recovering vessel existing apart from a recovering section for other mixed materials.

Title: Liquefied gas evaporator
Inventor: TANAKA KIHACHIROU
IPC: F17C9/02
Filed: 1979-04-16
Abstract: PURPOSE:To prevent an evaporator from being oxidized and to improve thermal efficiency, by housing a heat exchanger and a heat source in a tank which can be enclosed and by sealing up water and vapor as heat media in the tank. CONSTITUTION:A heating coil (heat exchanger) 5 is housed in an enclosable tank 1. Water sealed up in the tank 1 is controlled within a prescribed temperature range by a sheathed heater 3 and a temperature sensor 4. Liquefied gas, which flows in through a valve 7 and an inlet pipe 6, is evaporated by the heating coil 5 and then flows out to a liquefied gas combustion furnace or the like through a gas chamber 8, an outlet pipe 9, a valve 12 and a pressure regulator 13. Since the water in the tank 1 is kept in a sealed-up state, the inside surface of the tank 1 and the surface of the heating coil 5 do not rust and their lifetime is therefore lengthened. Since no steam leaks out, no heat loss is caused and economical efficiency is therefore improved.

Title: Magnetic recording medium
Inventor: KAWARAI MASAYOSHI
IPC: C09D5/23
Filed: 1983-03-20
Abstract: PURPOSE:To obtain a magnetic recording medium having a magnetic layer which has good surface smoothness and small surface electric resistance by incorporating conductive powder contg. at least tin oxide and antimony oxide in the magnetic layer. CONSTITUTION:Conductive powder contg. tin oxide and antimony oxide is incorporated in a magnetic layer. The conductive powder is exemplified by the powder consisting of tin oxide and antimony oxide or titanium oxide on which tin oxide and antimony oxide are deposited to form a conductive film thereon. The conductive powder having <=100OMEGA.cm specific resistance is preferable. The powder having a spherical shape with <=1mu particle size is adequate and if the powder having the particle size larger than said size is used, the surface smoothness is poor and noise is increased. The amt. of the conductive powder to be used is preferably within a range of 0.3-10wt% by the weight of the magnetic powder. The surface electric resistance of the magnetic layer is thus decreased without spoiling the surface smoothness of the magnetic layer.

IPC: F17C13/02
Filed: 1985-03-11
Abstract: PURPOSE:To keep pressure in an inner tank constant at all times, and to generate a high uniform magnetic field stably for a prolonged time by mounting an adjusting valve, which operates so that the pressure difference of a recovery line is made constant while using a vacuum in an outer tank as reference pressure, to the recovery line. CONSTITUTION:An adjusting valve 10 fitted to a recovery line 5 operates when pressure in an inner tank 2 exceeds a set value while employing a vacuum in an outer tank 4 as reference pressure. When the operating pressure of the adjusting valve 10 is set at the upper limit of pressure where pressure in the recovery line 5 varies by the starting and stopping of a compressor 7, pressure in the inner tank 2 is kept constant at all times at the ceiling value of the pressure variation of the recovery line 5. Accordingly, pressure in the inner tank 2 is held stably at a fixed value, thus continuously acquiring a high uniform magnetic field.

Abstract: PURPOSE:To obtain a bipolar IC of higher density by forming a resistor from the collector leading layer of a pnp type semiconductor. CONSTITUTION:Sb is diffused into a p type Si substrate 11 to form an n<+> buried layer 12, and an n epitaxial layer 13 is piled thereon. An SiO2 film 23 is opened 43 to pile a B-doped SiO2 33, which is thermally diffused to form a deep p<+> layer 16 and an element separating layer. At this time, the diffusion of B progresses more rapidly than that of Sb, so that a p layer 14 is newly formed. If the diffusion time is prolonged, the width of the p layer 14 in the direction of depth increases, and the peak concentration also becomes higher. Then, the SiO2 23 is removed, and SiO2 24 is newly provided and opened 44 to provide B-doped SiO2 34, which is thermally diffused to form a p<+> emitter 15, and electrodes E', B', and R' are attached to the base 13 and the p<+> layers. By said constitution, in the transistor manufacturing process, a transistor and a resistor can be simultaneously formed by simply setting the configuration of the collector pattern. In addition, by said constitution, a resistor can be formed solely, and combinations of various circuit elements can be formed in a short process, as well as they can be made to a minute sizes.

Abstract: PURPOSE:To prevent such an accident that only a cassette container is loaded in the empty state owing to erroneous insertion, by allowing a cassette front end to release lock of a sliding plate, and permitting the cassette container to move vertically. CONSTITUTION:When the front end of a cassette 1 contacting an inner wall 2a is further pressed in, the pawl 15a of a release plate releases the projection part 7c of the sliding plate 7, which is drawn back to open a guide hole 5b blocked by a slanting surface part 7 so far. When the cassette 1 is furthermore pushed in, the cassette container 2 moves vertically by the vertical component of a tension spring to load the cassette 1. When the cassette 1 is inserted erroneously in facing backward, the rear end 1c of the cassette 1 presses the projection of the cassette container 2, which moves horizontally, but the guide hole 5b is blocked by the slanting surface part 7b, so it is disabled to move vertically and not loaded.
