Abstract: Provided are a granulating device die, a granulating device cutter blade holder, a granulating device cutter blade unit, a resin-cutting device, and a granulating device, in all of which an increase in size is suppressed even when the processing amount is increased. The die (10) includes a bottom surface (10B), an upper surface (10A) having a radius smaller than a radius of the bottom surface (10B), a side surface (10C) that connects an outermost peripheral portion of the bottom surface (10B) and an outermost peripheral portion of the upper surface (10A), and a plurality of die holes (11) that discharge a resin raw material, the die holes being defined in the side surface (10C).

Abstract: A resin extruder capable of efficiently improving performance of kneading a resin material is provided. A resin extruder (1) according to one embodiment includes a cylinder (20), and a rotor-type screw (33) that is disposed in the cylinder (20) and kneads a resin material (51). In the rotor-type screw (33), a top part (33b) of a flight (33a) is formed in such a way that a gap between the top part (33b) and an inner surface of the cylinder (20) is changed from a front point to a rear point of the rotor-type screw in a rotation direction in a cross section that is vertical to an axial direction.

Abstract: The present invention discloses a cover-tape peeling apparatus for a tape feeder for peeling a cover tape released from a tape having a number of chip-like electronic parts sealed therein in a substantially equally spaced relation to wind and receive it into a reel. The apparatus comprises a first arm rotatably supported on a first shaft stood upright on a base of the tape feeder and having a ratchet meshed with a gear tooth formed in the outer peripheral portion of the peeling reel, a second arm having a cam portion in engagement with a cam portion provided on the first arm and rotatably supported on a second shaft, an arm push-down member in contact with the second arm to push down and rotate the second arm, and an urging body extended between both the arms and for rotating the first arm in response to the rotation of the second arm rotated by the arm push-down member so that the peeling reel is rotated through the ratchet.

Abstract: In a boiler or an industrial furnace, a temperature detecting sensor is mounted at the heat absorbing side of a heat pipe of a waste heat recovery device which is disposed in part of the path of exhaust gas. With an output signal of the temperature detecting sensor, a flow rate control valve is controlled, and a liquid discharging shield is utilized to maintain the flow rate of the liquid to be supplied in correspondence with the flow rate of the liquid to be discharged. The effective area of the heat pipes coming in contact with the liquid is varied to maintain the temperature at a heat absorbing side higher than the dew point of sulfur oxide, thus preventing the heat pipes from corrosion, exhaust ducts and so on, and allowing heat absorbing operation to be performed in accordance with the exhaust gas discharge temperature.
