Title: Hydrogen battery
Inventor: MITSUYASU KIYOSHI
IPC: H01M10/34
Filed: 1986-06-11
Abstract: PURPOSE:To lower solubility of hydrogen into electrolyte so as to prevent capacity deterioration of a hydrogen battery in storage time by making potassium carbonate contained in the electrolyte. CONSTITUTION:Potassium carbonate K2CO3 water solution is lower in its hydrogen dissolving power than, e.g., KOH, LiOH or NAOH water solutions in the same concentration generally used for alkaline secondary betteries. Therefore, in the case the K2CO3 added to the alkaline electrolyte, the hydrogen solubility in the electrolyte becomes much lower than the case of adding the same amount of the other alkaline electrolytes. Thus, capacity deterioration of a hydrogen battery in storage time can be prevented.

Accordingly, an opening  and closing control valve 14 continues to close an air bleed port 9 and the amount of ignition advanced angle is kept as it is decreased. Next, when the  vacuum in the suction air path 2 becomes small again, the non-return valve 20 is  closed promptly, therefore, the vacuum in both chambers 12, 33 becomes small  again, the opening and closing control valve 14 continues to close the air bleed  port 9, the amount of ignition advanced angle is kept in the decreased condition  and the fluctuation of the torque may be prevented.

Filed: 1996-05-29
Abstract: PROBLEM TO BE SOLVED: To make a driving voltage lower and to embody a high extinction ratio by adopting such a structure which negates a built-in electric field for the potential structure of quantum wells. SOLUTION: This modulator has the structure that the electron affinity in the one well layer increases toward a p-side and the energy at the top end of a valence band decreases toward then p-side. In this structure, the increase of the band discontinuous quantity of electrons may be nearly equal to 45meV and the decrease of the band discontinuous quantity of holes to 41meV. In other words, the linear changing of the band discontinuous quantity of the conductor band (electrons) and the valence band (holes) without changing the band gap within the one quantum well is possible.  The built-in potential changing within the one quantum well is 43meV in the actual built-in electric field if the built-in voltage is assumed to be 0.65V, the thickness of the i-layer inclusive of a MQW absorption layer to be 0.18μm and the width of the well layer to be 12nm and, therefore, the negation of the built-in electric field is made possible by this structure.
