Abstract: In a crawler type work machine, when switching from a pivot turning mode to a straight travel mode or a slow turning mode, a controller is configured to maintain a rotation speed of the turning motor until after a first timing at which the inside steering clutch begins partial engagement.

Abstract: To provide a gas passage adjustment mechanism that can be reduced in size. A smoke evacuator 1 (gas passage adjustment mechanism) includes a pressing member (12), a solenoid (13), a tube holder (14), a first protruding member (15), and at least one second protruding member (16). The first protruding member (15) is provided at a position facing a pressing position (P) where the pressing member (12) presses the tube (11), and protrudes from the tube holder (14) in a direction toward the pressing member (12). The at least one second protruding member (16) is disposed at an upstream position and a downstream position of the passage with respect to the pressing position (P), and protrudes toward a side of the tube (11).

Abstract: A medical water trap 20 includes a container 22, a partition wall 40, an inner cylinder 28, and a projecting portion 44. An intake port 34 and a discharge port 36 are formed in the container. The partition wall divides an internal space 38 of the container into a space 38A on the intake port side and a space 38B on the discharge port side. The inner cylinder communicates with the intake port and extends toward the partition wall in a space on the intake port side. The projecting portion is formed to project from the partition wall toward the intake port side and surround the inner cylinder when the partition wall is viewed from the intake port side in a plan view. At least one opening 42 is formed in the partition wall on a side closer to the wall surface of the container than the projecting portion.

Abstract: The disclosure relates to a microbicidal composition with excellent action of limiting a decrease in durability of synthetic adhesives as well as high microbicidal action. The microbicidal composition contains 0.03 to less than 1.0 mass % of peracetic acid, 0.045 to less than 1.5 mass % of hydrogen peroxide, and 0.036 mass % or more of glycine.

Abstract: A tool holder is provided with a main body, a taper cone, a working portion, a coolant flow passage, and an adjuster. The taper cone includes a taper portion and movable in an axial direction of the main body. The working portion is mounted on an outer peripheral portion of the main body and includes a taper bottom surface which engages with the taper portion. The taper bottom surface is movable in a radial direction of the main body based on a movement of the taper cone in the axial direction. A coolant flows through the coolant flow passage such that a part of the coolant presses and moves the taper cone in the axial direction and another part of the coolant flows out to an outside so as to adjust a pressing force. The adjuster is fitted into a hole penetrating the main body and includes a coolant flow-out hole for adjusting a flow-out of the coolant.
