IPC: H01L29/786
Filed: 1998-08-26
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method of a thin-film transistor, which can manufacture a thin-film transistor of top-gate structure having excellent characteristics on an insulating substrate having a low heat-resisting temperature such as a plastic substrate. SOLUTION: After a polycrystal Si film 15 is formed on a plastic substrate 11 through a buffer layer 12, a gate electrode 18 comprising an Si film is formed on the film 15. By introducing impurities into the polycrystal film 15 with the gate electrode 18 as a mask, a source region 19 and a drain region 20 are formed. From the upper side of the gate electrode 18, an ultraviolet pulse-laser beam 21 by excimer laser is applied. The gate electrode 18 is locally heated, and a gate insulating film 16 undergoes heat treatment. At the same time, the impurities in the gate electrode 18, the source region 19 and the drain region 20 are electrically made active.

Title: Hydrogen storage alloy electrode for alkaline storage battery
Inventor: MINOURA SATOSHI
IPC: H01M4/24
Filed: 1996-09-11
Abstract: PROBLEM TO BE SOLVED: To suppress the generation of an oxygen gas on a hydrogen storage alloy electrode even if over discharge is conducted by containing calcium carbonate in the active material layer of the electrode containing hydrogen storage alloy and having the active material. SOLUTION: Calcium carbonate is contained in an active material layer. When the calcium carbonate is added, the oxygen generating potential of a hydrogen storage alloy electrode becomes a nobler potential. When the calcium carbonate is contained in the active material layer, the generation of an oxygen gas on the hydrogen storage alloy electrode can be suppressed even if over discharge is conducted. As the result, the oxidization of the hydrogen storage alloy can be suppressed so that the deterioration of hydrogen storage characteristics can be suppressed. Preferably, the containing amount of the calcium carbonate is 0.1 to 3.0 percentage by weight against the hydrogen storage alloy.  When the containing amount of the calcium carbonate becomes 0.1 percentage by weight or more, the rate of discharge capacity after the over discharge to the discharge capacity before the over discharge becomes high. When the same exceeds 3.0 percentage by weight, the temperature characteristics of a battery at a low temperature are deteriorated, and battery characteristics are deteriorated.

Title: Air purifier
Inventor: HIRAYAMA YASUTAKA
IPC: F24F7/06
Filed: 1984-11-15
Abstract: PURPOSE:To improve the catching power of oil mist or the like and enable to improve the surrounding atmosphere by a structure wherein the ionization wires of an electrostatic precipitation part and dust collecting electrodes are opposedly provided to each other and a light- transmitting hood, at the upper part of which a lighting equipment is provided, is employed. CONSTITUTION:An electrostatic precipitation part 3 consists in alternately disposing in an array duct collecting electrodes 7, which are protruded forward, and accelerating electrodes 8, which are located backward as compared with the duct collecting electrodes, and providing ionization wires 9 ahead of the duct collecting electrodes 7 by a certain distance and attaching a lighting equipment such as fluorescent light or the like at the upper position, which is nearer to the center, of a hood 2. When high tension electric current and voltage are applied between the ionization wires 9 and the dust collecting electrodes 7, corona currents flow from the ionization wires 9 to the dust collecting electrodes 7. In this case, ions collide with air molecules, resulting in forcibly flowing the air to the dust collecting electrodes 7. On the other hand, dusts in the air are charged by the ionic currents flowing between the ionization wires 9 and the dust collecting electrodes 7. When the charged dusts flow between the accelerating electrodes 8 and the dust collecting electrodes 7, the dusts are applied by coulomb force due to the electric field and the charges on the dusts, resulting in pushing the dusts to the dust collecting electrode 7 side in order to be caught by the electrodes. Thus, the oil soot or the like developed at a heating cooker A can be caught efficiently by being assisted with the updraft of the oil soot.

Abstract: PURPOSE:To decrease power consumption and to lower manufacturing cost, by determining a position of a recess such that a permanent magnet is apart from the recess when an armature is stabilized by the permanent magnet and a return spring and the permanent magnet is faced with the recess when the armature is actuated by excitation of a coil. CONSTITUTION:Position of a recess 9d is determined such that a permanent magnet 5 is away from the recess 9d when an armature 2 is stabilized by the permanent magnet 5 and a return spring 15, and the permanent magnet 5 is opposed to the recess 9d when the armature 2 is actuated by excitation of a coil 1. If the armature 2 is in the returned state, the coil 1 is not excited and magnetic flux generated by the permanent magnet 5 flows through a path phi1. When current is supplied to the coil 1 in the same direction to that of magnetic flux of a path phi1 flowing across a gap G4, the magnetic flux passes through a path phi2 and the recess 9d is opposed to the pole N of the permanent magnet 5 as the armature 2 is moved. Thereby, a magnetic circuit whose magnetic force is provided by the permanent magnet 5 is opened. In this manner, the gaps G1-G4 are closed and a closed magnetic loop not passing the permanent magnet 5 is formed.
