Abstract: A liquid pipetting apparatus for dispensing liquid of minute volume for use in a survey instruments of a hemanalysis machine, a genetic screening, and a pharmaceutical screening, etc., is disclosed. The liquid pipetting apparatus comprises a liquid holding member for holding the liquid, and capable of dispensing the liquid from one end, and a driving member for moving the liquid holding member forward and backward along the dispensing direction, the liquid holding member being moved by the driving means, thereby dispensing the liquid held on the liquid holding member.

Abstract: The connection member has a conductor portion (13) and a dummy pattern portion (15) both formed of a metallic conductor and arranged on a base (11). The conductor portion (13) and the dummy pattern portion (15) are formed by etching. The dummy pattern portion (15) has a positioning portion (21) formed by etching away the metallic conductor. The base (11) has a positioning hole (21) formed by applying laser light having a wavelength of 1500 nm or more to the positioning portion.

Abstract: A connector provides electrical connection between an object (21) to be connected having contact portions (23) and a mating connection object (31) having mating contact portions (33). The connection is achieved when the connector is in contact with the contact portions (23) and the mating contact portions (33). The connector has a base member (11), elastic members (13) provided on the base member, electrically conductive patterns (15a, 15b) arranged on the base member so as to provide electrical connection between the front and back surfaces of the base member, and terminals (17) arranged on the elastic members (13) so as to be in contact with the contact portions (23) and the mating contact portions (33). The terminals (17) and the conductive patterns (15a, 15b) are connected to each other. Those portions of the base member (11) where either elastic members (13) or conductive patterns are provided are shaped in a mesh-like form.

Abstract: A fixed member is fixed to a rotation shaft. The rotation member is rotatably fitted to the rotation shaft. In a state in which one of end surfaces of the rotation shaft abuts against one of side surfaces of the fixed member, the rotation shaft and the fixed member are welded and fixed to each other by high density energy beams radiated from a direction of the other side surface of the fixed member.

Abstract: A method of manufacturing an organic semi-conductor solid electrolytic capacitor wherein a conductive polymer thin film layer of a heterocyclic compound, i.e., pyrrole, thiophene or furan, is formed as a solid electrolyte on the surface of a metal substrate having a dielectric oxide film formed thereon by electrolytic oxidation polymerization carried out in an electrolytic solution which contains pyrrole, thiophene or furan as a heterocyclic compound and an aliphatic or aromatic sulfonic acid or a salt thereof as a supporting electrolyte in an organic solvent, for example, acetonitrile, acetone or propylene carbonate.
