  • Publication number: 20100276891
    Abstract: A combination seal is attached to a bearing comprising a fixed element and a rotating element which rotate relative to each other, so as to seal an inner side and an outer side of the bearing. The combination seal is comprised of a seal ring and a slinger. The seal ring is comprised of a reinforcing ring and an elastic seal supported by the reinforcing ring. A leading end side of the elastic seal, supported by the reinforcing ring extending toward the slinger, is brought into contact with a surface of the slinger, which is opposite to the seal ring, when the combination seal is attached to the bearing. During a combining work process, when combining the seal ring and the slinger to form the combination seal, a seal lip does not turn over and the seal lip can be held toward a predetermined direction without using a specific jig during the combining work process and without being particularly careful during performance of the combining work process.

  • Patent number: 7763387
    Abstract: Since a first layer (a carbon layer 2a) whose chief ingredient is carbon and a second layer (Li absorbing layer 3a) containing particles having a theoretical capacity greater than that of graphite are formed on anode collector 1a, high capacity and high operation voltage can be realized. Since a element having a theoretical capacity equal to or less than that of graphite is added to the particles constituting this second layer, expansion and contraction of volume according to the charge and discharge are suppressed. This enables capacity deterioration to be suppressed even though cycles go on.

  • Patent number: 7748388
    Abstract: It is disclosed that a long elevation time is obtained and the efficiency of resection can be improved by providing an endoscopic injectable preparation using high molecular weight hyaluronic acid having an average molecular weight of 1,500,000 to 3,000,000 or its salt. In treating early cancer or other neoplastic mucosal lesion, the lesion is resected with handling of an endoscope (“endoscopic mucosal resection”) instead of performing a major surgical operation such as laparotomy, thoracotomy or organ excision. In performing endoscopic mucosal resection, physiological saline, or a solution of low molecular weight hyaluronic acid or its salt is injected into a stratum below the site of lesion scheduled for resection to elevate the site of lesion, thereby increasing the efficiency of resection. To raise the efficiency of endoscopic mucosal resection, however, the development of an injectable preparation presenting a longer elevation time and requiring a low injection pressure has been desired.

One seal member includes an elastic seal formed in such a manner as to be supported by the reinforcing ring of this seal member, with the elastic seal extending toward the other seal member such that a seal portion is formed between the elastic seal and the other seal member. The other seal member includes an encoder on a side of the flange portion of the other seal member that is opposite a side facing the one seal member. The one seal member includes an elastic element formed in such a manner as to be supported by the flange portion of this seal member.

  • Patent number: 7737270
    Abstract: Provided is a method for producing a pigment, in particular, a metal phthalocyanine, in high yield and in a green process. The method has (1) a step of obtaining a solution mixture by mixing at least one type of compound serving as a raw material for a pigment with a solvent, and (2) a step of obtaining the pigment by reacting the compound while holding the solution mixture at not less than a temperature where a subcritical state or a supercritical state of the solvent occurs.

  • Publication number: 20100025852
    Abstract: To suppress deterioration in reliability of wiring and to reduce effective dielectric constant of wiring. In a semiconductor device, copper-containing wirings are covered by barrier insulating films, and the barrier insulating films contain a component of an organic silica containing unsaturated hydrocarbon and amorphous carbon. The copper-containing wirings are covered by the barrier insulating films that contain a component that is in an organic silica structure containing unsaturated hydrocarbon and amorphous carbon. Accordingly, inter-wiring capacitance is reduced without deteriorating reliability of the copper-containing wiring, thereby realizing a high-speed LSI with low power consumption.
