Title: Membrane for concentrating aqueous solution of volatile organic liquid, use and preparation thereof
Inventor: FUJII YOSHINARI
IPC: B01D61/36
Filed: 1987-01-13
Abstract: PURPOSE:To obtain a membrane, which concentrates an aqueous solution of a volatile org. liquid, having high separation capacity, by coating a polyvinylidene fluoride porous membrane with a silicone polymer without closing the pore parts on the surface thereof. CONSTITUTION:Dried polyvinylidene fluoride hollow yarn membranes are bundled and both ends thereof are potted with an epoxy adhesive to form a hollow yarn bundle which is, in turn, internally filled and impregnated with a non- solvent of polyvinylidene fluoride showing the compatibility with the solvent of a coating solution, for example, methanol. After excessive methanol is removed by passing nitrogen gas through the hollow yarn bundle, the coating solution of a silicone polymer is allowed to fill the hollow yarn bundle and, after standing, nitrogen gas is allowed to pass through said hollow yarn bundle to evaporate the solvent. The membrane thus obtained for concentrating an aqueous solution of a volatile org. liquid is inserted in a case to form a membrane module and the concn. of the aqueous solution of the volatile org. liquid of a liquid-liquid system such as an aqueous ethanol solution is performed.

Filed: 1982-01-14
Abstract: PURPOSE:To increase the mobility of the carrier flowing through a thin layer and thus obtain a high speed FET, by forming the thin layer of single crystal, when forming source and drain regions on a semi-insulating substrate such as GaAs, then providing a semiconductor thin layer on the surface therebetween, and thus providing a gate electrode via a gate insulation layer thereon into an FET. CONSTITUTION:On the semi-insulating substrate 11 constituted of GaAs, etc., without using the semiconductor layer of normal polycrystal or amorphousness, a single crystal semiconductor thin film 12 with lattice constant different from that of the substrate 11 is epitaxial-grown. Next, an N<+> type source region 13 and a drain region 14 are diffusion-formed through this thin layer 12, and, on the thin layer 12 positioned between these regions, a gate electrode 18 is adhered via a gate insulation film 17. Thus constituted, a gate voltage is impressed between a source electrode 15 and a gate electrode 18, and the current flowing between the source electrode 15 and a drain electrode 16 is controlled by this voltage. In this manner, since the mobility of the carrier flowing through the thin layer 12 exceptionally increases, the FET is operated at a high speed.

Title: Manufacture of variable resistor
Inventor: HAYASHI MICHIHIKO
IPC: H01C1/14
Filed: 1996-01-16
Abstract: PROBLEM TO BE SOLVED: To improve accuracy of position angle detection for a variable resistor. SOLUTION: A pre-molded substrate 14 formed by compression-molding an electrically insulating mold material and an external connection metal material 15 are fitted into a metal mold. High pressure molding by heating is performed to unify the pre-molded substrate 14 and the external connection metal terminal 15 to form a mirror surface with their surfaces flush with each other, thus forming a molded substrate 16. On the surface of the molded substrate 16, a conductor layer 17 and a resistance layer 18 are molded, adhered in contact, and hardened. Even with an electrically insulating mold material having a large rest angle, the molded substrate 16 of mirror surface with uniform charging density is provided and the conductor layer 17 and the resistance layer 18 do not behave in terms of process history while good surface roughness may be maintained.  Therefore, detection of position angle with high accuracy may be realized.

Title: Contactless ignition system
Inventor: OKAMURA MASAKI
IPC: F02P5/155
Filed: 1979-01-22
Abstract: PURPOSE:To control advance in a wide degree of freedom changing ignition timing between medium speeds and high speeds by changing the gate voltage of a thyristor between the off state and on state of a transistor that controls the thyristor which generates ignition signals. CONSTITUTION:As a transistor 17 is off at low speeds, a current which flows from a pulser coil 3 enters the gate of a thyristor 11 entirely via resistors 12 and 13. Therefore, the thyristor 11 is triggered at early appropriate ignition positions. As the number of revolution is increased, charging voltage to a capacitor 8 is increased and the transistor 17 becomes on. Between the off and the on states, a transient period M exists while the transistor 17 changes from off to on. As the period M is passed through when the transistor becomes on, the current flowed to the gate of the thyristor 11 is shunted to the collector of the transistor and ignition timing is delayed.

IPC: H01S5/00
Filed: 1990-01-12
Abstract: PURPOSE:To improve a semiconductor laser in degree of freedom of design and to decrease it in cost and to protect a protective film against heat distortion at heating by a method wherein the protective film formed of aluminum nitride(AlN) is provided to a reflective mirror. CONSTITUTION:A protective film 27 which is free from pinholes and formed of aluminum nitride(AlN) chemically and thermally stable is formed on a reflective mirror 6 of a semiconductor laser. Therefore, the protective film 27 has a function enough to serve as a protective film, so that a case charged with nitrogen gas used to supplement the protective function of the protective film 27 can be eliminated. By this setup, a semiconductor laser can be improved in degree of freedom of design and lessened in cost, and as an aluminum nitride(AlN) film is proximate to an active layer (AlNGaAs) in linear expansion coefficient, the crystal of the film can be protected against heat distortion at heating.

IPC: G06K9/46
Filed: 1982-01-18
Abstract: PURPOSE:To improve both the stability and accuracy for recognition of characters, by discriminating the input character by means of a feature matrix formed with a prescribed number of divisions to decide the dividing number suited to the degree of complicacy and forming a feature matrix again if the decided dividing number is not coincident with the prescribed number of divisions.

IPC: G05F1/56
Filed: 1979-01-20
Abstract: PURPOSE: To obtain a stabilizing power source circuit with which the effective use is ensured for the battery power source by changing the bias of the control transistor according to the battery power source or the AC rectifying power source which is used to the non-stabilizing power source.  
     CONSTITUTION: In case the non-stabilizing power source which is supplied to terminals 1 and 1' is the battery, switch 17 is at the position shown in the diagram. And transistor 3 is biased by the voltage obtained from the pulse voltage of the secondary winding of the flyback transformer of television 11 functioning as the load and via rectifier circuit 12. When the input voltage of terminals 1 and 1' drops down, transistor 3 is controlled to secure the sufficient saturation. Thus the voltage drop due to transistor 3 is decreased, thus securing the effective use of the battery voltage. In case the rectifying power source is connected to terminals 1 and 1' each, switch 17 is switched to terminal 171. Transistor 3 is controlled to cause some voltage drop at all times, and thus the ripple component can be decreased to load 11.
