Title: Storage device of fuel cell
Inventor: HARADA TAKASHI
IPC: H01M8/04
Filed: 1987-11-12
Abstract: PURPOSE:To reduce the deterioration of performance and the loss of gas, and to make the maintenance unnecessary, by providing an expansion chamber which composes a nonpressure sealing chamber for the enclosed gas linking to a fuel gas chamber and an oxide gas chamber at the outside of a phosphoric acid type fuel cell, and nonpressure-sealing the enclosed gas. CONSTITUTION:A fuel gas chamber and an oxide gas chamber of phosphoric acid type fuel cell 1 are linked to an expansion chamber 15 through manifolds 2A, 2B, 3A, and 3B, and a connecting pipe 16, and the expansion chamber 15 forms a nonpressure sealing chamber. Then, by operating a lid plate 19, an N2 sealing valve 17, manifolds, and the like, N2 gas is fed to the expansion chamber 15 in the amount sufficient to absorb the variation of the gas volume owing to the temperature variation, to form a nonpressure sealing chamber. Since the fuel gas chamber and the oxide gas chamber are short-circuited by the connecting pipe 16, in this case, the difference of pressure between the both chambers is made zero. And since the nonpressure sealing chamber is maintained at the nonpressure sealing condition during the storage, the difference of pressure with the outer air is made almost zero. Consequently, the deterioration of performance owing to the moisture absorption of the phosphoric acid solution and the blowing-out of the phosphoric acid solution can be prevented, and the maintenance of the pressure is made unnecessary.

Title: Pyroelectric type infrared sensor
Inventor: IWASAKI KATSUSHI
IPC: G01J5/34
Filed: 1988-11-11
Abstract: PURPOSE:To prevent the generation of an induction noise by connecting a resistance in series to both of a drain electrode and a source electrode of an EFT within a shield case or to the source electrode alone. CONSTITUTION:In a pyroelectric type infrared sensor which houses a pyroelectric element 1 and an FET 2 in a shield case 6, resistance rD and rS are connected in series to, for example, both of a drain electrode D and a source electrode S of the FET 2 respectively. Thus, the resistances rD and rS work on a high frequency induction noise as impedance larger than a reactance component. Thus, these resistance can act on a low frequency infrared detection signal as DC-oriented resistance element.

Abstract: PURPOSE:To fix tightly a tracking spring and a focus spring with thin adhesives and to improve stability in a servo system by dividing some of a lens supporting member, an intermediate supporting body and a fixed supporting body with the fitting part of a tracking spring and a focus spring as a part of a boundary. CONSTITUTION:An objective lens lens-barrel 11 is divided into an inside part 11a and an outside part 11b with the fitting part of a tracking direction moving parallel spring 12 as a boundary, and to the part, the upper edge part of a tracking spring is respectively bonded. In this case, while the inside part 11a and the outside part 11b are divided, respective parts can be processed independently, and therefore, they can be processed to an arbitrary thickness in accordance with the thickness of the tracking spring 12. Thus, the thickness of the adhesives to bond the tracking spring 12 can be made very thin, the spring constant of the adhesives can be much larger than the spring constant in the focus direction of the tracking spring 12.
