摘要： There is provided a power module production method that is capable of stably producing a power module with highly reliable properties, and so forth. The power module production method produces a power module 1 by stacking a cooler 5, an insulating resin sheet 4, a heat sink block 3, and a semiconductor chip 2, wherein a first insulating resin sheet 41, which forms a lower layer of the insulating resin sheet 4, is first bonded to the cooler 5 by thermal compression. Next, with a second insulating resin sheet 42, which forms an upper layer of the insulating resin sheet 4, interposed between the first insulating resin sheet 41 and the heat sink block 3, the second insulating resin sheet 42 is bonded to the first insulating resin sheet 41 by thermal compression, and the heat sink block 3 is bonded to the second insulating resin sheet 42 by thermal compression. The semiconductor chip 2 is then soldered onto the heat sink block 3. Thus, bonding defects at the respective bonding interfaces are prevented, and dielectric breakdown of the insulating resin sheet 4 is prevented.

摘要： A refrigerant mixture which scarcely effects the ozonosphere in the stratosphere, is less likely to cause global warming, and can be used as such together with conventional compressor lubricating oils other than ester oil in a conventional refrigeration cycle plant. The mixture comprises 80 to less than 100 % by weight of difluoromethane and at least one member selected among at most 20 % by weight of cyclopropane, at most 10 % by weight of isobutane, and at most 5 % by weight of butane.

摘要： A light shutter array element has a plurality of separate electrodes that are formed in parallel and in two or more columns and that are independently served with a predetermined voltage, and a common electrode that so extends as to divide the separate electrodes for each of the columns, that has branch electrode portions extending in a branched manner in a direction to be interposed among the separate electrodes in each of the columns, the separate electrodes and the common electrode being formed on the surface of an electrooptical crystal substrate. The basic feature resides in that the distances are different at a predetermined ratio from the right and left neighboring separate electrodes on both sides of the branching electrode portion of the common electrode to said branching electrode portion. The method of driving the light shutter array element has the basic feature that during the off time of the drive pulse voltage, a short-time pulse voltage is applied to the electrodes in such a manner that the total number of times of the application of said drive pulse voltage and the short-time pulse voltage always becomes constant per a unit time. Further, the PLZT for the light shutter array element is characterized in that the PLZT which forms the sintered product has an average grain size of smaller than 5 νm and has an average grain sectional area of smaller than 1/150 of the area of the dot that is formed.
