IPC: G10H7/00
Filed: 1990-06-27
Abstract: PURPOSE:To reduce the capacity of a waveform data storage device and to obtain an inexpensive device by selecting the bit length of sample data to the necessary medium and storing it, adding dummy bits of prescribed bits to the lower level of each sample data which is read out and converting it to sample data of prescribed bit length, and D/A-converting this signal.

Title: Manufacture of electrolyte retaining matrix for fuel cell
Inventor: USAMI AKIRA
IPC: H01M8/02
Filed: 1988-07-07
Abstract: PURPOSE:To enhance the permeability and retainability of electrolyte by mixing together and kneading a plastitizer, binder agent, and electrolyte retainer consisting of silicon and silicon carbide, thereupon performing the molding process, and removing the plastitizer from the molding by means of extraction of solvent. CONSTITUTION:An electrolyte retaining matrix uses electrolyte retaining agent which is a granular admixture containing silicon carbide and silicon excellent in affinity with electrolyte such as phosphoric acid, and therein no baking process is applied. As the surface of this electrolyte retaining agent is not covered with a binder agent fibrillated in the mixing and kneading process, the electrolyte is provided with enhanced permeability and retainability. Because no baking process is applied, the electrolyte retaining matrix has ample flexibility. In case therefore an electrolyte retaining matrix retaining electrolyte such as phosphoric acid is laminated between a pair of gas diffusion electrodes followed by application of a surface pressure, the contact of electrode with the electrolyte retaining matrix is made closer, and the ohm loss based on the contact resistance can be sunk.

Filed: 1984-08-17
Abstract: PURPOSE:To simply improve the load characteristic of a motor by switching the gain of an error amplifier according to the magnitude of the rotating speed of the motor. CONSTITUTION:After the output of a rotating speed detector 3 is detected as an AC signal and converted into a voltage by a frequency/voltage converter 5, it is compared by an error amplifier 6 with a reference voltage Vref. If the output of the converter 5 is higher than a reference voltage 8a, the output of the comparator 8 increases, a switch 6e closes, and the gain of the amplifier 6 becomes 6c/ 6b. If the output of the converter 5 is lower than the voltage 8a, the output of the comparator 8 decreases, and the switch 6e opens, and the gain of the amplifier 6 becomes (6c+6d)/6b. Thus, the load characteristic of the motor can be improved.
