Title: Corona discharger
Inventor: YAMAZAKI NORIAKI
IPC: G03G15/02
Filed: 1983-05-10
Abstract: PURPOSE:To prevent the distribution of a discharge current which flows in the lengthwise direction of a corona discharge electrode from becoming uneven with small power consumption by providing a device which applies lengthwise expansion strain to the corona dischrge electrode. CONSTITUTION:The operationof an oscillator 16 is controled by a control mechanism 17, and when a signal R1 is inputted with a copy button 18 turned on, the oscillator 16 is driven until the completion of copying operation to vibrate a vibrator 14 for the copying operation. Consequently, a metallic thin wire 15 for discharge is extended and contracted lengthwise during the copying operation, and lengthwise strain is generated among metallic crystal lattices repeatedly at a short period. Consequently, electrons are emitted from the surface of the metallic thin wire 15 for discharge through an exo-electron emission phenomenon, so secondary electron operation necessary for corona discharge is supplemented to increase corona discharge current density. Consequently, the density distribution f ions generated near the metallic thin wire 15 is made uniform lengthwise.

Title: Solid high molecular type fuel cell
Inventor: HIRANO SHINICHI
IPC: H01M8/10
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To eliminate a humidification mechanism for an oxidizing gas so as to be compact by adjusting, so that a decreasing water content with the oxidizing gas on a cathode catalyst electrode side is equal to the sum of a produced water content through oxidization reaction on the electrode and a moving water content from a fuel-supplied anode side catalyst electrode side via a solid high molecular electrolyte film. SOLUTION: A moving water content from a humidified hydrogen-supplied anode side to a cathode side is the difference of electric penetration flow with protons movement and the reverse diffusion flow of reaction produced water, and is changed according to the supply amount of a humidifying water content and the film thickness of a solid high molecular electrolyte film. The supply amount of the humidifying water content and the water content accompanying air or the like is changed according to a temperature. As the adjustment means for the water content when the air is not humidified, preferably the electrolyte film thickness is set to about 20 to 80 μm, and the operation temperature is set to about 50 to 70 deg.C. Although a thinner film thickness is preferable, an output characteristic deteriorates resulting from gas leakage when the thickness is 20 μm or less, and the output is reduced resulting from anode side dry out, when the temperature becomes less than about 50 deg.C.
