Title: Fuel cell
Inventor: MITSUTA KENRO
IPC: H01M8/02
Filed: 1986-09-04
Abstract: PURPOSE:To make it possible to preserve a sufficient amount of electrolyte, by forming a porous first electrode base material with either the front side or the back side attached to a catalyst layer, and a second electrode base material with the mean pore diameter smaller than that of the first electrode base material, at an oxidizer electrode base material. CONSTITUTION:One side of a flat and porous first electrode base material 15 is attached to a catalyst layer 3. A porous second electrode base material 16 has grooves 13 through which a reaction gas is fed, and its ribs 11 are contacted to the first electrode base material 15 while its webs 12 are attached to a separator 14. Moreover, the mean pore diameter of the electrode base material 15 is larger than that of the electrode base material 16. In a fuel cell thus composed, the oxidizer gas passes through the grooves 13 which are the passages of the reaction gas, and through the porous electrode base material 15, and reaches to the catalyst layer 3. Therefore, in the electrode base material 16 with the ribs 11 and the webs 12, a sufficient amount of electrolyte can be preserved without disturbing the gas diffusion.

Patent JP-H0260311-A (JP)
Title: Differential amplification circuit
Inventor: INAMI DAIJIRO
IPC: H03F3/45
Filed: 1988-08-26
Abstract: PURPOSE:To stabilize a differential amplifying circuit even when an in-phase input voltage range is expanded up to the vicinity of the threshold limit by connecting plural current source transistors in parallel and giving respective different reference voltages to the gate. CONSTITUTION:The gate voltages of plural current source transistors(TR) MN 3-MNn are set to respective different voltage values. A current flowing at TRs MN1, MN2 to form a differential pair is the sum of the current fed from individual TRs MN3, MN4-MNn. At the time of plural current sources in the range of an input voltage Vin<Vg, an error between an input and an output is gradually increased. This is the reason why the gate voltages of a TRs MN 3-MNn are separately set. Even when the threshold voltage becomes higher, the current from TRs MN3, MN4, etc., to set low the gate voltage becomes zero, and from highly set, for example, MNn, the current is fed. Consequently, it does not occur that the current flowing at the differential pair becomes zero and the amplifying circuit is not operated.
