Publication number: 20240146142Abstract: [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.Type: ApplicationFiled: October 26, 2023Publication date: May 2, 2024Inventors: Akihiko Eguchi, Shota Nogiwa, Yuki Suzuki, Tamotsu Tanaka

Patent number: 6491466Abstract: 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.Type: GrantFiled: December 3, 2001Date of Patent: December 10, 2002Assignee: Mitsubishi Pencil Kabushiki KaishaInventors: Tamotsu Eguchi, Kenzi Sato, Makoto Ono
