Inventor: SAKAI TETSUO
IPC: H01M10/24
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To increase tensile strength, ion exchange capacity, and electrolyte retainability by attaching a solution prepared by dissolving a sulfonation copolymer which is a copolymer of aromatic vinyl monomers and diene monomers or its hydrogenation product and has a sulfonic group and/or sulfonate group in a nonaqueous solvent to the skeleton of a porous sheet, then removing the solvent. SOLUTION: A copolymer is a copolymer of vinyl monomers having an aromatic group and a sulfonic (sulfonate) group and diene monomers or a copolymer of monomers having diene structure and a sulfonic (sulfonate) group and aromatic vinyl monomers. The total content of the sulfonic group or the sulfonate group to the aromatic vinyl monomer and diene monomer is preferable to be 0.2-4.0 mmol/g. By using a separator prepared by physically, uniformly attaching the sulfonate to the porous sheet made of olefin family organic fibers, high rate discharge characteristics are enhanced, self discharge characteristic and cycle life is lengthened.

Title: Calculator for flow passing through heat sink
Inventor: NISHIHARA ATSUO
IPC: G06Q50/00
Filed: 1996-04-03
Abstract: PROBLEM TO BE SOLVED: To exactly perform numerical value calculation for flow passing through a heat sink with a small-sized calculator by replacing the heat sink with a resistor for fluid. SOLUTION: Distributions of variables (u), (v), (w) and (p) are determined as an initial state, and resisting force exerted on the resistor simulating the heat sink is calculated by equations I and II. However, Lf: length in the direction parallel with flow of heat sink, ρ: fluid density, De: the relative diameter of a flow passage between fins, uf and wf : a component parallel with flow of average flow velocity between the fins found by calculation, and another component vertical to the flow and parallel with the fin, and f, Kc and Ke: constants. And calculated resisting force is substituted for Fx and Fz of the right side of the equations III-V and the equation of continuity VI is included to solve them.  Next, calculation is cancelled as correct answer could be obtained at the time point where a difference between both the sides at the time when values of each valuable are substituted, i.e., a residual difference is smaller than a certain constant value. Thereby numerical calculation can be exactly performed with a small-sized calculator.

Abstract: PURPOSE:To provide a semiconductor device with a miniature element and to improve the integrity of the element, by providing an insulation film around a gate electrode in a self-aligning manner and forming a channel with the use of the insulation film as a mask. CONSTITUTION:A thermal oxidation film 3 is formed on a region 2 in a substrate 1 where an impurity is diffused. Ions are implanted in a second diffusion region 5. Subsequently, an insulation layer 6 is applied thereon. A film 7 having good draping properties is further applied thereon. When the film 7 and the insulation layer 6 are etched until a gate electrode 4 is exposed, a part of the insulation layer 6 remains unetched. When the gate electrode 4 is etched with a mask of the insulation film 6, the insulation film 6 defines projections on the side wall thereof. When an insulation film 8 is deposited, it has a larger thickness around the gate electrode and a smaller thickness in the central region. The insulation film 8 is etched until the central region of the gate electrode 4 is exposed, and ions are implanted with a mask of the insulation film 8 so as to cancel the concentration of the impurity in the diffusion region 2 and to form a channel 9.

Title: Four-wheel drive vehicle
Inventor: YOSHIDA SHIGEYUKI
IPC: B60W10/16
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To switch the driving state of a vehicle appropinately according to the stuck state of the vehicle by putting a differential gear in a direct-coupled state when at least one of front wheels and rear wheels to which driving force is transmitted is put in a slipping state. SOLUTION: In case of judging direct-coupled four-wheel drive entry conditions, vehicle speed V is compared with the specified value V4 (S172), the absolute value |ΔVc | of propeller shaft rotation difference is compared with the specified value ΔVc3 (S174), and travel load resistance fv is compared with the specified value fv3 (S178). In case the vehicle speed V is the specified value V5 or less and select high rotating speed difference ΔVt is larger than the specified value ΔVt1 , a stuck state is judged (S182). The stuck state of a vehicle such as a one-wheel stuck state or a diagonal stuck state, and a slipping state of either one of wheels can therefore be detected appropriately.  In case of the vehicle being in the stuck state, a driving mode command is switched from a full time four-wheel drive mode to a direct-coupled four-wheel drive mode to obtain excellent driving performance.

IPC: H02M5/45
Filed: 1980-06-16
Abstract: PURPOSE:To eliminate the lowering of a power factor caused by a reactive power by providing a chopper for controlling a DC current and a polarity changeover switch for flowing a coil current in both directions. CONSTITUTION:There are provided a rectifier 2 for rectifying full wave of alternating current supplied through a transformer 1 for a rectifier, a current controlling chopper 4 opening or closing with high frequency wave between the output side of the rectifier 2 and a load (trochoidal magnetic field coil) 6, and a polarity inverting switch 5 for inverting the polarity of the current supplied to the load from the chopper 4.

Abstract: PURPOSE:To obtain an exterior illumination system which automatically lights lamps mounted in a main lighting fixture and in an auxiliary lighting fixture only when a person passes by using a lighting control means to be provided at a lower part of a pole to control flashing of the lamps in the main lighting fixture and the auxiliary lighting fixture. CONSTITUTION:When an infrared sensor 8 provided in a storage box 4 detects a slight change in the quantity of heat due to infrared radiation from the human body of a passerby coming close to the box 4, a sensor unit 7 is operated by the detection output of the sensor 8 and lights lamps 3, 5 mounted in a main lighting fixture 2 and an auxiliary lighting fixture 6, respectively, both of which fixtures 2, 6 are installed at a pole 1. When a period of time set by a delay timer 9 elapses after the lamps are lighted, i.e., the passerby has gone and there is no need of illumination, the sensor unit 7 is operated by the delay timer 9 and the lamps 3, 5 are both turned off. An exterior illumination system is thus lighted for a period of time during which illumination is necessary for the passage of the passerby, and the lamps are turned off after the passerby has gone, and so exterior illumination is effectively carried out at night while greatly saving power and fully realizing safety of passage and the effect of crime prevention.

Oxygen diluted with Ar is introduced, temperature is raised, the polycrystalline silicon surface is oxidized, and a silicon oxide film 33 of 1nm in thickness is formed. Further an upper layer composed of a polycrystalline silicon layer is deposited. By heat treatment in a high temperature atmosphere containing phosphorus oxychrolide, the polycrystalline silicon layers 31, 32 are doped with phosphorus, and the resistivity is decreased. At this time, since the silicon oxide layer 33 exists, the crystal grain boundary of the upper layer and the lower layer becomes discontinuous.
