  • Publication number: 20080299271
    Abstract: The invention is to provide a process for producing a liquid food, characterized by subjecting at least one of coffee, a milk composition, a food material (liquid) containing a component(s) having an antioxidation ability (radical-scavenging activity) and mixed liquids containing one(s) of them to an electrolysis treatment and/or a current passage treatment. Since the invention can prevent quality deterioration of coffee or milk composition over a long period of time without using additives and also improve safety, it is appropriate for producing canned coffee, milk-containing coffee or milk-containing tea drink to be sold in vending machines or can warmers. Further, since the invention can improve the antioxidation ability of foods, the resulting foods can suppress the in-vivo increase of active oxygen and free radicals, it greatly contributes to health.

  • Publication number: 20080133792
    Abstract: An information processing device for reducing the time required for the data transfer as much as possible while displaying information of the data transfer state in synchronization with the data transfer. The information processing device is equipped with a counter for counting the number of pieces of data having been transferred in a data transfer. When a large number of pieces of data is to be transferred in the data transfer, the number of pieces of data having been transferred is displayed every time a certain number of pieces of data, not one piece of data, are transferred.

  • Publication number: 20080116526
    Abstract: A semiconductor device of the invention has a plurality of resistor elements formed on an element isolating oxide film in predetermined regions on a surface of a semiconductor substrate. Active regions are furnished close to the resistor elements. This allows the element isolating oxide film near the resistor elements to be divided into suitable strips, forestalling a concave formation at the center of the element isolating oxide film upon polishing of the film by CMP and thereby enhancing dimensional accuracy of the resistor elements upon fabrication.

  • Publication number: 20080048707
    Abstract: The accuracy of effective channel width extraction in drain current method is improved. There are prepared a transistor with a wide channel width serving as a reference, and a transistor with a narrow channel width that becomes a candidate for extraction (step ST1.1). From the characteristic curve of a plane formed by mask channel width and source-drain conductance, there is extracted a virtual point at which the change of source-drain conductance is estimated to be approximately zero even if the gate overdrive is finely changed. Then, the value of function F is calculated which is defined by the difference between the change of the conductance at the coordinate of the virtual point and the product obtained by multiplying the conductance per unit width by the change of the mask channel width (step ST1.6). From a shift amount (?) which minimizes the standard deviation of the function F to be obtained (step ST1.

  • Publication number: 20080024972
    Abstract: Provided is a buffer member helping to achieve stable electrical connection between a casing of an external storage device and an accommodating portion thereof without involving an increase in the number of components. A buffer member has a conductive connection layer held in contact with a hard disk drive and with an accommodating portion, so it is possible to dissipate static electricity with which the hard disk drive is charged and electromagnetic wave noise through the conductive connection layer to the accommodating portion or a casing of a notebook PC electrically continuous with the accommodating portion. Thus, it is possible to prevent malfunction of the hard disk drive and to correctly operate the notebook PC. Further, there is no need to separately provide a conductive member for conductive connection between the hard disk drive and the accommodating portion, thereby making it possible to avoid an increase in the number of components.
