The front caseand the rear caseare connected to each other at a plurality of hole partsarranged at a plurality of positions within a facing surface. The front casehas a resin partformed of a resin, and a sheet metal partwhich is formed of a metal and is at least partially embedded in the resin part. The sheet metal parthas a main body partsurrounded by the hole parts; and an extending partextending from the main body partup to a position closer to the connecting partthan a hole partA,B arranged closer to the connecting partthan the main body partand embedded in the resin part

A catalyst for producing alkylene oxide including fine metal silver particles dispersed and supported on a carrier, wherein not less than 90% of the fine metal silver particles have silver particle diameters of 2 to 100 nm, is disclosed. The catalyst can be produced by impregnating a carrier with a liquid containing a silver compound or a silver ion; drying the carrier; and then irradiating the carrier with microwave to form fine metal silver particles in dispersed state on the carrier. This catalyst is used for producing olefin oxide by contact gas-phase oxidation of olefin by a molecular-oxygen-containing gas.

Catalyst for producing alkylene oxide, method for producing the same, and method for producing alkylene oxide using said catalyst

A catalyst that enables to produce ethylene oxide in a high selectivity and a method for the production of ethylene oxide using the catalyst are provided. In the catalyst for the production of ethylene oxide, wherein the catalyst component is supported by a carrier, a carrier containing &#x3b1;-alumina as the main component which has at least two peaks in the range of pore diameter of 0.01-100 &#x3bc;m and at least one peak of the above peaks is present in the range of pore diameter of 0.01-1.0 &#x3bc;m in the pore distribution measured by mercury porosimetry is adopted as said carrier.

A battery includes a battery cell having a pair of terminals, a circuit board disposed on a side of the battery cell, a pair of connecting members, one end of each connecting member being attached to a respective end of the circuit board, and the other end of each connecting member being attached to the respective terminal of the battery cell, a connector having a resin path, the connector provided on the circuit board, and a molded resin portion continuously formed via the resin path, covering the circuit board and the connecting members disposed on the battery cell.
