  • Patent number: 11746227
    Abstract: Provided is a thermosetting resin composition which can suppress liquid dripping or bleeding from generating even when used for filling a hole in a printed wiring board having a large opening diameter of a hole part such as a through hole, and in particular, which can suppress cracks from generating even when used for filling a hole in a multilayer printed wiring board having a conductive part and an insulating part on the inner wall of a hole part such as a through hole. The thermosetting resin composition according to the present invention has a viscosity ratio R expressed by formula V2/V1 in the range of 5.0×10?2 to 1.0×102, wherein V1 (dPa·s) is the viscosity measured by a cone-flat plate type rotational viscometer (cone-plate type) in accordance with JIS-Z 8803:2011 and V2 (dPa·s) is the minimum value of the melt viscosity measured at 60° C. to 100° C.

  • Patent number: 9636478
    Abstract: A medical tube, which is inserted into a tubular organ and discharges and suctions fluid, is provided with a tube-shape main body which extends a prescribed length and with a valve which is disposed in a portion of the main body that is inserted into the tubular organ and can discharge or suction a fluid, wherein the valve includes multiple slits which are formed so as to extend axially of the body a prescribed length, reaching from the outer periphery to the inner periphery of the main body, and which are provided spaced in the circumferential direction of the main body. Each slit is formed tilted in the same direction with respect to a radially-extending line which passes through the axial center of the main body.
