Abstract: A centrifugal separator includes a rotator part that separates a liquid sample and has a rotor and a drive part. The rotor receives a liquid sample therein and rotates to separate the liquid sample. The drive part drives the rotor to rotate. A controller part controls operations of the rotator part which is mounted in a rotator casing. A controller casing which is separate from the rotator casing mounts the controller part, and the controller part is connected via a drive wire to the drive part in the rotator part. The rotor casing is disposed at a clean room, the controller casing is disposed outside the clean room, and the drive wire passes through a wall of the clean room via an air-tight sealing mechanism.

Abstract: A combustion-type power tool includes a housing, a cylinder head, a cylinder, a push lever, a piston, a combustion-chamber frame, and an urging member. The cylinder head is disposed at a first end of the housing. The cylinder is disposed in and fixed to the housing. The cylinder has an inner space. The push lever is disposed at a second end of the housing. The piston is slidably disposed in the cylinder and is reciprocally movable in an axial direction. The combustion-chamber frame is disposed in the housing and provides a combustion chamber in cooperation with the cylinder head and the piston. The urging member has one end attached to the piston and another end attached to an axial end of the cylinder, thereby urging the piston in a direction from the second end toward the first end.

Abstract: A centrifugal separator includes a rotator part, a controller part, and a first control panel. The rotator part has a rotor for separating components in a liquid sample, and a drive shaft for driving the rotor to rotate. The controller part controls operations of the rotator part. The first control panel is provided with a first operating part for setting operating conditions of the rotator part including the desired rotating speed of the rotor and the desired operation period of time of the rotor, and a first display unit for displaying the operating conditions and status of the rotator part. A second control panel having the same functions as the first control panel is provided in a location separate from the controller part. Hence, a user can check the operating status of the centrifugal separator and set and modify operating conditions for the centrifugal separator not only by using the first control panel but also by using the second control panel.

Abstract: A swing rotor for centrifugal machines is provided. The rotor comprises a rotor body around which plural arms are disposed. A through hole is formed in place through each arm. Plural buckets are arranged around the rotor body so as to be swingable between two arms. Each rotor pin is inserted through each through hole to be arranged in a direction of a normal line to a rotation axis of the rotor body, so that two buckets are swingably supported by both ends of each rotor pin. Each end of the rotor pin is shaped into an outwardly extended taper form having a predetermined taper angle made to a center axis of each rotor pin. The taper angle is substantially equal to an angle made between a swinging axis of each bucket and the center axis of each rotor pin. This reduces failures in swing motions of the buckets.
