Title: Reforming catalyst for fuel battery and fuel battery using the catalyst
Inventor: SAITO TAKESHI
IPC: B01J27/232
Filed: 1990-05-28
Abstract: PURPOSE:To obtain a steam reforming catalyst suitable for an economical directly inside impregnated-type molten carbonate fuel battery without lowering activity due to adhesion of molten carbonate by impregnating a chromium- containing nickel porous body with lithium carbonate and potassium carbonate. CONSTITUTION:A chromium-containing nickel porous body, which is a metallic material to be used as an anode of a molten-carbonate fuel battery, is impregnated with lithium carbonate and potassium carbonate to obtain the title catalyst. The catalyst does not lower the effect as a reforming catalyst even if the molten carbonate adheres to the reforming catalyst owing to its evaporation or scattering when the catalyst is used in an anode chamber of a molten-carbonate fuel battery. Preparation of the catalyst involves impregnating a plate-like porous body, which is prepared by the same method for an anode for the battery, with carbonates consisting of lithium carbonate and potassium carbonate and then forming the plate-like body by cutting into pieces, and filling a reforming chamber installed in the inside of a fuel battery with the resulting pieces. Impregnation with molten carbonate is carried out, for example, directly at high temperature.

Title: Speaker cabinet
Inventor: USUKI SAWAKO
IPC: H04R1/02
Filed: 1993-06-10
Abstract: PURPOSE:To attain a flat sound pressure frequency characteristic suppressing the reduction of low frequency characteristics by setting up an elliptic cylinder as a basic shape and setting up a face obtained by cutting the side face of the elliptic cylinder in parallel with the axial direction of the cylinder as a front plate. CONSTITUTION:An elliptic cylinder having a cross-sectional shape like a pseudo elliptic shape constituted of plural circular arcs is set up as a basic shape and a speaker cabinet is constituted of a front plate 1 consisting of a face obtained by cutting the side face of the cylinder in parallel with the axial direction of the cylinder, a side plate 2 consisting of plural circular arc side faces and a speaker unit fixing part 3 arranged on the center of the front plate 1 as main bodies. Since the diffraction of a sound wave emitted from a diaphragm arranged on the corner part of the speaker unit can be reduced, the disturbance of sound pressure frequency characteristics due to interference between a sound wave generated due to diffraction and the sound wave emitted from the diaphragm can be suppressed. Since the side plate of the elliptic cylinder is used as a pseudo buffle plate, the reduction of a sound pressure level in low frequency can also be suppressed.
