  • Patent number: 10163202
    Abstract: The present invention provides an automatic blood-sampling tube preparation device which can detect the presence of the proper or improper blood-sampling tube by selectively taking out a blood-sampling tube and transferring the blood-sampling tube to a label pasting position, printing information of the patient on a label, pasting the printed label on the blood-sampling tube positioned in the label pasting position, and collecting the label pasted blood-sampling tubes in the container for each patient. The device also includes photographing means for photographing an appearance of the blood-sampling tube taken out from the blood-sampling tube containing section and a control means arranged to have a threshold with respect to at least one characteristic information previously extracted from an appearance of a blood-sampling tube, to extract the characteristic information from the appearance image photographed to judge whether the blood-sampling tube corresponds to the instruction information from the doctor.

  • Patent number: 9443655
    Abstract: To increase the heat resistance of a film capacitor, a dielectric resin composition is used as a material for a dielectric resin film used in a film capacitor, the dielectric resin composition being cured by mixing and crosslinking two or more organic materials having functional groups that react with each other to provide a cured article. At least one pair highly cohesive atomic groups which has a molecular cohesive energy equal to or higher than that of a methyl group and capable of cohering with each other due to the molecular cohesive energy is linked to the organic material. The highly cohesive atomic groups form a cohesive portion serving as pseudo-crosslinking.

  • Patent number: 9416216
    Abstract: To increase the heat resistance of a film capacitor, a cured article obtained by curing a mixed solution of a polyvinyl acetal having a hydroxyl group content of 10% to 38% by weight, the number of backbone carbon atoms of the polyvinyl acetal being 100 or more, and a polyisocyanate having an isocyanate content of 1% to 50% by weight is used as a dielectric resin films material arranged between first and second counter electrodes facing each other. At least the polyvinyl acetal is subjected to high-pressure homogenization in which a shearing force is applied such that a pressure applied to the polyvinyl acetal is 50 MPa or more when the material is passed through a path having a diameter of 0.125 mm and a length of 5 mm, so that the solubility is increased to allow a curing reaction to proceed uniformly. The cured article has a glass transition temperature of 130° C. or higher and a breakdown voltage of 350 V/?m or more.

  • Patent number: 8130485
    Abstract: When external electrodes of a multilayer ceramic capacitor are formed by performing direct plating on surfaces at which internal electrodes are exposed without forming paste electrode layers, bonding forces of plating layers are relatively weak, and in addition, when glass particles are included in the plating layers, blisters are often generated. To overcome these problems, a multilayer ceramic capacitor is formed by performing electrolytic plating using a plating bath including glass particles, electrolytic plating layers including glass particles dispersed therein are formed as the external electrodes.
