  • Patent number: 8163424
    Abstract: A secondary battery includes: a positive electrode; a negative electrode; a porous electron-insulating layer adhered to a surface of at least one selected from the group consisting of the positive electrode and the negative electrode; and an electrolyte. The porous electron-insulating layer comprises a particulate filler and a resin binder, and the particulate filler comprises an indefinite-shape particle comprising a plurality of primary particles that are joined to one another. A neck is preferably formed between the primary particles. Since the porous electron-insulating layer has high porosity, it is possible to obtain a secondary battery that exhibits excellent low-temperature characteristics, which are particularly important in actual use, and that is capable of discharging at a large current.

  • Patent number: 8067058
    Abstract: The amount of a paint for forming a porous heat-resistant layer supplied to the outer surface of a gravure roll is adjusted by removing the paint with a blade that is disposed so as to contact the outer surface. A resin blade is used, and the position at which the resin blade contacts the outer surface of the gravure roll is changed as the resin blade wears away. This prevents the amount of the paint for forming the porous heat-resistant layer removed from the outer surface of the gravure roll from changing as the resin blade wears away, so that the excess amount of the paint carried on the outer surface of the gravure roll is removed with good accuracy. An almost constant amount of the paint is thus transferred to an electrode surface from the outer surface of the gravure roll, and a porous heat-resistant layer with an almost uniform thickness is stably formed on an industrial scale.

  • Publication number: 20110273970
    Abstract: An optical information recording medium (1) includes, on a substrate (50), a ROM layer (20), a RE layer (40), an intermediate layer (30) separating the ROM layer (20) and the RE layer (40), and a cover layer (10) provided in a position farthest from the substrate (50). The RE layer (40) is an information recording layer provided in a position farthest from the light transmitting layer and also is a recording layer of disc type identification information and an individual identification number recorded in a format allowing easier determination as compared to an information recording format used in the layer allowing only readout of information by use of light irradiation. Therefore, it becomes easy to check a disc type in a recording/reproducing device and one recording/reproducing device can be shared with other types of optical disks. Further, disk production becomes easy.

  • Patent number: 8039044
    Abstract: A plurality of gravure rolls are rotated while being allowed to abut against a surface of a moving electrode hoop, thereby applying a coating fluid serving as a precursor of porous layers onto a plurality of linear mixture layers. In this way, a plurality of linear porous layers are formed on the associated linear mixture layers formed on the surface of the electrode hoop. In this case, the location at which each gravure roll abuts against the surface of the electrode hoop is controlled according to variations in the lateral location of associated one of the mixture layers independently of the other gravure rolls.

  • Patent number: 7995646
    Abstract: A communication test circuit for allowing a tolerance test to be carried out in a general testing environment. The communication test circuit includes an adder and a second clock generation block. When an offset is input to the adder, the adder adds the offset to a phase adjustment signal for adjusting the phase of a clock signal for data detection and outputs the result to the second clock generation block. The second clock generation block outputs a second clock signal adjusted in accordance with the phase adjustment signal to which the offset has been added. Accordingly, a clock signal shifted in accordance with the offset from a natural clock signal along the time axis is generated at a test.

  • Patent number: 7989295
    Abstract: A semiconductor substrate made of a semiconductor material is prepared, and a hetero semiconductor region is formed on the semiconductor substrate to form a heterojunction in an interface between the hetero semiconductor region and the semiconductor substrate. The hetero semiconductor region is made of a semiconductor material having a bandgap different from that of the semiconductor material, and a part of the hetero semiconductor region includes a film thickness control portion whose film thickness is thinner than that of the other part thereof. By oxidizing the hetero semiconductor region with a thickness equal to the film thickness of the film thickness control portion, a gate insulating film adjacent to the heterojunction is formed. A gate electrode is formed on the gate insulating film. This makes it possible to manufacture a semiconductor device including the gate insulating film with a lower ON resistance, and with a higher insulating characteristic and reliability.
