Abstract: A joining system (100) of the present invention is for joining a joining target (W) including first, second, and third members (W1), (W2), (W3), and includes a welder (101), a friction stir welding machine (102), and a controller (110) that: (A) causes the welder (101) to weld the second and third members (W2), (W3); (B), after (A), causes the joining target (W) to be placed at the friction stir welding machine (102) so that the first member (W1) is opposed to a distal end of a tool (10); and (C), after (B), controls a linear motion driver (7) and a rotation driver (8) so as to, while pressing the distal end of the tool (10) to the joining target (W), rotate the tool (10) around an axis, so that the softened second and third members (W2), (W3) intrude into the softened first member (W1), thus joining the joining target (W).

Abstract: This power conversion device has: a current measurement unit for measuring phase current; a current vector calculation unit for calculating a current vector by performing 3-phase to 2-phase conversion on the phase current; an amount-to-be-analyzed calculation unit for calculating, on the basis of the current vector, an amount to be analyzed; and a feature amount waveform extraction unit for extracting a waveform in a specific frequency range on the basis of the amount to be analyzed.

Abstract: The present invention relates to a retardation film having biaxial characteristics or an achromatic property, which is obtained by uniaxially stretching of a film composed of cellulose derivatives in which a hydroxyl group of cellulose is substituted by an acyl group having 5 to 20 carbon atoms, preferably 7 to 20 carbon atoms, more preferably 8 to 20 carbon atoms or cross-linked compounds of cellulose derivatives, said retardation film is a superior retardation film which has negative birefringence and excellent optical characteristics and also can be easy to obtain by uniaxially stretching, and in addition, the heat resistance, tearing strength and the like which are weaknesses of cellulose ester are improved.

Abstract: There are provided isolated polynucleotide fragments for use in diagnosing and/or developing treatments for schizophrenia. Further provided is a method for diagnosing schizophrenia using one or more polynucleotides disclosed herein. Also provided is a method for screening a compound which regulates expression of a schizophrenia-related gene. Also provided is a chronic animal model of schizophrenia that mimics the functional deficits observed in patients and methods for producing the animal model comprising the administration of PCP to the animal.

Abstract: The present invention provides a new use of the polynucleotide of SEQ ID NO:1, NO:3 and NO:5 or fragments thereof, or the polypeptide encoded from that polynucleotide in the field of the schizophrenia.

Abstract: An entry board for drilling improves drill machinability such as hole positional accuracy using a fine-diameter drill, and roughness of the walls of the drilled holes. The entry board has a metallic foil, and a thermosetting resin is covered on one or both sides of the metallic foil to provide a drill-penetrating layer.
