  • Publication number: 20200215631
    Abstract: Provided is a taper reamer with which it is possible to achieve an improvement in machining accuracy and machining life. The taper reamer comprises a plurality of cutting edges each having a helical shape provided on the outer periphery of a cutting-edge portion having an external diameter being expanded from a front end toward a rear end thereof, wherein an intertooth angle, defined between each of a pair of the cutting edges adjacently arranged in a circumferential direction, is different from one another at any given reference position, and wherein the plurality of cutting edges each have a helix angle that is different from one another. As the plurality of cutting edges that are unequally partitioned each have the helix angle that is different from one another, a resonance during cutting can be prevented.

  • Publication number: 20200215764
    Abstract: A method attaches a liquid-repellent filter to an air vent of a resin molded article accommodating a component/electronic part. A thermal processing tip and a thermally welding tip and a molded article are provided. The thermal processing tip (22) forms a filter attachment surface (14) at the inlet or outlet of an air vent (16) in a thermoplastic resin molded article (13). A filter fixing rib (15) is formed around the attachment surface. The porous filter (18) is dropped onto the filter attachment surface, and a thermal welding tip (2) is used to melt the filter fixing rib such that the melted resin flows onto and covers a circumferential edge portion of the filter, penetrating the body of the filter. The melted resin penetrating the filter 18 and covering the circumferential edge portion of the filter are cooled to solid, whereby the filter is fixed to the filter attachment surface.

  • Patent number: 10689393
    Abstract: Novel tetrahydroisoquinoline derivative compounds are disclosed herein that may be used as an active ingredient for a pharmaceutical composition, and in particular, for a pharmaceutical composition useful for preventing or treating a disease or condition responsive to modulation of the contractility of the skeletal sarcomere. This may be accomplished, for example, by modulation of the troponin complex of the fast skeletal muscle sarcomere through one or more of fast skeletal myosin, actin, tropomyosin, troponin C, troponin I, and troponin T, and fragments and isoforms thereof. The tetrahydroisoquinoline derivative compounds can thus be used as an agent for preventing or treating 1) neuromuscular disorders, 2) disorders of voluntary muscle, 3) CNS disorders in which muscle weakness, atrophy, and fatigue are prominent symptoms, 4) muscle symptoms stemming from systemic disorders, and 5) dysfunctions of pelvic floor and urethral/anal sphincter muscle.
