20130148314 | CIRCUIT BOARD FOR PERIPHERAL CIRCUITS OF HIGH-CAPACITY MODULES, AND A HIGH-CAPACITY MODULE INCLUDING A PERIPHERAL CIRCUIT USING THE CIRCUIT BOARD - A drive circuit is laminated via a high exothermic element disposed on a power circuit, and it is configured so that the average thermal expansion coefficient of the side of the power circuit of the drive circuit board may be larger than the average thermal expansion coefficient of the side opposite to the power circuit. Thereby, the drive circuit board will be curved in the same direction as the power circuit board when the power circuit board is curved due to heat generation from the high exothermic element accompanying the operation of the module. Thereby, in a high-capacity module, while attaining reduction in size and weight, reduction in serge, and reduction in a loss, poor junction between the high exothermic element of the power circuit and the drive circuit board can be suppressed and heat generating from the high exothermic element can be more effectively released. | 06-13-2013 |
20090011926 | PROCESS FOR PRODUCING DDR TYPE ZEOLITE MEMBRANE - A method for producing a DDR type zeolite membrane, comprising immersing a porous substrate in a raw material solution containing 1-adamantanamine, silica, and water; and carrying out a hydrothermal synthesis of DDR type zeolite in the presence of a DDR type zeolite seed crystal (seed crystal) to form a DDR type zeolite membrane on the surface of the porous substrate by making a content ratio of 1-adamantanamine to silica (1-adamantanamine/silica) in the range of 0.002 to 0.4 in terms of molar ratio and a content ratio of water to silica (water/silica) in the range of 10 to 500 in terms of molar ratio, and an average particle diameter of the seed crystal to 300 nm or less to provide a method for producing stably a DDR type zeolite membrane of uniform and thin membrane thickness with high gas permeability. | 01-08-2009 |
