  • Publication number: 20240146142
    Abstract: [Problem to be Solved] High positional accuracy of connection terminals should be achieved in a bus bar unit for a motor. [Solution] A method for manufacturing a busbar unit (10) according to the present invention includes a step of molding a power connection terminal member (14) integrally with a resin plate (12) by insert molding, and a step of attaching the busbar to the power connection terminal member (14) so as to connect electrically each other. The power connection terminal member (14) has a power connection terminal (14a) for connecting to the motor control board, and an attachment portion (14b) for attaching to a bus bar electrically connected to the coils of the stator. The power connection terminal (14a) and the attachment portion (14b) protrude from the resin plate (12) individually. The attachment portion (14b) of the power connection terminal member (14) is welded to the attachment portion of the busbar.

  • Publication number: 20240088742
    Abstract: A cover member for a motor unit is disclosed. The cover member is interposed between a motor and a control substrate for controlling operation of the motor. The motor has a bus bar terminal electrically connected to a coil of a stator of the motor. The control substrate has a connection terminal that is fitted to the bus bar terminal and is made to electrically connect the control substrate to the stator. The cover member has a through hole, through which the bus bar terminal pierces, and an enclosing part for enclosing a fitting location for the bus bar terminal and the connection terminal, as seen in a piercing direction of the bus bar terminal.

  • Publication number: 20140020702
    Abstract: A method for providing highly luminous or highly masking ornamentation or make-up on a nail and the skin, wherein an applicator filled with a coating liquid which contains at least water and an O/W type emulsion resin and which has tackiness even after drying is used to coat the coating liquid on a nail and the skin in the form of optional shapes and characters, and then the coated drawn lines are dried; a transfer foil is pressed to contact with the coated drawn lines endowed with tackiness; and the foil is peeled off, whereby highly luminous or highly masking drawn lines are transferred, or wherein coloring material powders are pressed to contact with the foregoing coated drawn lines endowed with tackiness without using a transfer foil, and the powders left outside the coated drawn lines are brushed off, whereby highly luminous or highly masking drawn lines are obtained.

  • Patent number: 6491466
    Abstract: An applicator includes a reservoir charged with fluid. The reservoir has a discharge-controlling mechanism at one end for applying the fluid. The fluid contains at least one organic solvent, such as mythylcyclohexane, and is charged with a scarcely volatile liquid substance, such as an alkylene oxide adduct of diglycerin, having no compatibility with the applying fluid. The scarcely volatile liquid substance forms a movable plug for an end part of the applying fluid in a contact state and the rear of the plug in the reservoir is released to the atmosphere. The applicator can include writing instruments including a felt tip pen and a ballpoint pen, a corrector, an applicator for adhesive and a dressing instrument.
