Title: Phosphoric acid type fuel cell
Inventor: SAKAYORI MITSUO
IPC: H01M8/02
Filed: 1991-08-30
Abstract: PURPOSE:To provide a fuel cell having a continuously stable output voltage by improving the structure of a reserver and by inhibiting an aged decrease in the performance of a fuel cell due to the decrease of a phosphoric acid. CONSTITUTION:A matrix 1 for retaining a phosphoric acid between an oxidant electrode 2 and a fuel electrode 3 is fixed by sandwiching the matrix 1 by an upper seal inner frame 11 and a lower seal outer frame 10. The upper seal inner frame 11 and the lower seal outer frame 10 compose a reserver 8 filling the phosphoric acid in its entire periphery. The phosphoric acid in the reserver 8 is directly connected to the entire periphery of tire outer end part of the matrix 1. This increases phosphoric acid storage amount in the reserver 8, dramatically increases an interval between the replenishing timing of the phosphoric acid, and decreases the frequency of operation suspension, trying the inhibition of a deterioration in the performance of a fuel cell. In addition, replenishing pathes are increased by the replenishment of the phosphoric acid from the entire periphery of the outer end part of the matrix 1. The movement of the phosphoric acid to the matrix 1 is quickly done to equalize the replenishment of the phosphoric acid, materializing stable operation and prolonged life.

Title: Piezoelectric sound producer
Inventor: NAKAGAWARA MUTSUYUKI
IPC: G10K9/122
Filed: 1984-10-22
Abstract: PURPOSE:To obtain a sound producer which has a stable characteristic and has a high acoustic pressure, by providing projecting parts on the faces, which a piezoelectric buzzer element is adhered to and its outside peripheral part is brought into contact with, of a resin case. CONSTITUTION:Projections 11 and 12 are provided on a face 9, with which a piezoelectric buzzer element 3 is brought into contact, and an outside peripheral part 10 of a resin case 7. When the piezoelectric buzzer element has the outside peripheral part supported by the case with an adhesive to constitute the sound producer, the oscillation of the piezoelectric buzzer element 3 for sound production is attenuated by the adhesive having elasticity because the piezoelectric buzzer element 3 is adhered to projections 11 and 12 of the resin case 7 through this adhesive. Thus, the stable characteristic is held because the resin case 7 is not oscillated.

Title: Drive circuit for switching element
Inventor: MORITA KAZUKI
IPC: H03K17/16
Filed: 1992-07-28
Abstract: PURPOSE:To prevent mis-ignition of the switching element by connecting a capacitor and a diode between a base terminal and an emitter terminal of the switching element and adding a resistor in parallel with the diode. CONSTITUTION:When a voltage with a high dv/dt is applied between a collector and an emitter of a transistor(TR) 1 in the turn-off state, a current resulting from the dv/dt with a steep rising in the direction from the collector to the base flows through a junction capacitor 4 between the collector and the base of the TR 1. When a wiring distance between a reverse bias power supply 3 and the TR 1 is long and a wiring impedance 5 is in existence, the dv/dt current does not flow into the reverse bias power supply 3 but is absorbed by a capacitor 2 through a diode 6. Thus, no dv/dt current flows into the base of the TR 1 and the TR 1 is not turned on. Furthermore, even after the dv/dt current is absorbed by the capacitor 2 and the capacitor 2 is charged up, a resistor 7 is inserted in series to the capacitor 2 in the wiring path on the discharge side of the capacitor 2 and the vibration at the discharge side is suppressed.
