Abstract: PURPOSE:To enable the time required for hydrogen storage alloys to absorb or release hydrogen to be reduced by increasing heat exchange through a heat pipe located between a heat medium chamber provided with a hydrogen gas entrance and a filling chamber filled up with hydrogen storage alloys, both of the chambers being divided by a diaphragm. CONSTITUTION:When hydrogen gas is fed through a hydrogen gas entrance 2a and a fan 7 is set in motion, the low temperature air, as the outside air, is sent through an air hole 1a into a thermo-medium chamber 1. A working fluid within a heat pipe 4, which is condensed on the side of the thermo-medium chamber 1, moves to the side of the filling chamber 2, where it evaporates to take the heat of reaction originated from the absorption of hydrogen away from the hydrogen storage alloys M. And then, the working fluid returns to the side of the thermo-medium chamber 1, where it is condensed by cooling in the low temperature air. The then low temperature air, of which the temperature is raised, is discharged through a through hole 1b outside the thermo-medium chamber 1. Thereby, said hydrogen storage alloy M, of which the heat of reaction originated from their absorption of hydrogen is taken away through the action of the heat pipe 4, is enabled to absorb and store up hydrogen.

Abstract: PURPOSE: To improve the workability, extensibility and compactness by the simultaneous use of both the magnetic cursor and the function switching menu sheet, and thus to increase the reading speed with the cost reduction.  
     CONSTITUTION: Both magnetic cursor 4A and function switching menu sheet 9A are used at one time, and the normal reading of the pattern is carried out via cursor 4A to enhance the workability as much as possible. And the lacking function caused by the number of the push-buttons of 4A is supplemented by providng the function which can give the reallotment when necessary via sheet 9A. In other words, the frame of 9A functions to give a collective alteration to the correspondence relation between push-button 7 of 4A and the pattern function, and thus 7A which is one of push-buttons 7 is utilized for menu switching. As a result, the various circuit functions are memorized in menu memory circuit 19 in accordance with the combinations of the function switching menu frame numbers and the push-buttom numbers, and thus the function is altered when necessary by pressing button 7A of 4A.
