  • Publication number: 20110229614
    Abstract: It is intended to provide a method of treating fish meat whereby the amount of so-called drip flowing out from fish meat, which is obtained by disassembling, cutting and forming landed fish and then freezing, in the course of the treatment and thawing can be largely reduced. This object is achieved by pre-drying molded fish meat, which has been prepared by disassembling landed fish and cutting them into various shapes, with a cold air so as to lightly dehydrate the surface part, dipping the fish meat in an aqueous solution of sodium chloride for a short period of time so that the fish meat surface turns into a gel to form a coating, vacuum-packaging it as such, further blowing a clean gas such as oxygen into the package to give a gas-containing package, then freezing it by the brine freezing method and storing in that state. Due to a series of the treating procedures as described above, the amount of the drip during thawing the fish meat is considerably reduced.

  • Patent number: 7745903
    Abstract: A technique is provided which permits formation within a single chip both a field effect transistor of high reliability capable of suppressing the occurrence of a crystal defect and a field effect transistor of a high integration degree. In a mask ROM section having an element isolation region with an isolation width of smaller than 0.3 ?m, a planar shape of each active region ACT is made polygonal by cutting off the corners of a quadrangle, thereby suppressing the occurrence of a crystal defect in the active region ACT and diminishing a leakage current flowing between the source and drain of a field effect transistor. In a sense amplifier data latch section which is required to have a layout of a small margin in the alignment between a gate G of a field effect transistor and the active region ACT, the field effect transistor is disposed at a narrow pitch by making the active region ACT quadrangular.

  • Patent number: 7692234
    Abstract: A semiconductor device, which ensures device reliability especially in fine regions and enables great capacitance and high-speed operations, has memory cells including, in a first region of a main surface of a semiconductor substrate, a gate insulating film, a floating gate electrode, an interlayer insulating film, a control gate electrode, and source and drain regions of the second conduction type arranged in a matrix, with a shallow isolation structure for isolating the memory cells. When using a shallow structure buried with an insulating film for element isolation, the isolation withstand voltage in fine regions can be prevented from lowering and the variation in threshold level of selective transistors can be reduced. When the memory cells in a memory mat are divided by means of selective transistors, the disturb resistance of the memory cells can be improved.

  • Patent number: 7282411
    Abstract: An AND flash memory of the type wherein a memory cell is constituted of n-type semiconductor regions (a source and a drain) formed in a p-type well of a semiconductor substrate and three gates (including a floating gate, a control gate and a selective gate) is manufactured. In the manufacture, arsenic (As) is introduced into a p-type well in the vicinity of one of side walls of the selective gate to form n-type semiconductor regions (a source and a drain). Thereafter, to cope with a drain disturb problem, the substrate is thermally treated by use of an ISSG (In-Situ Steam Generation) oxidation method so that a first gate, insulating film disposed in the vicinity of one of side walls, at which the n-type semiconductor regions have been formed, is formed thick.

  • Publication number: 20070186824
    Abstract: A sidewalk tile with snow-removal function is stably obtained that is capable of being heated to a desired temperature, while at the same time sufficiently maintaining strength. A heat-generating concrete body is obtained by mixing particle-form (granular) or powder-form carbon material with un-hardened concrete at a specified ratio, and then pressing it with a high-pressure press at a pressure of approximately 980 kN to remove moisture and to form it into a tile shape. A pair of electrodes are embedded in end sections on both ends in the width direction of the heat-generating concrete body. The outer surfaces of the heat-generating concrete body are covered with an insulation-coating layer. One side and the circumference of the heat-generating concrete body are covered with un-hardened concrete and formed into a single tile shape by pressing with a high-pressure press to obtain a sidewalk tile with the snow-removal function.
