Abstract: A throttle unit is equipped with a grooved block including at least one minute groove formed on a plane surface, and an opposite block having a plane surface which is opposite to the minute groove. The grooved block and the opposite block are detachably joined so as to be opposite to each other. A throttle fluid path is formed by the minute groove and the plane surface of the opposite block. At least one surface of each of the minute groove is constituted by a curved surface or an inclined surface that is inclined with respect to the plane surface of the grooved block.

Abstract: A vacuum pressure supply system comprises: a plurality of vacuum pressure supply paths for supplying a vacuum pressure from a vacuum source to a holding unit that holds an object using the vacuum pressure; a pressure adjusting mechanism that adjusts the pressure in the vacuum pressure supply paths to obtain mutually different holding forces for holding the object; and a switching mechanism that switches the connection state of the vacuum source and the plurality of vacuum pressure supply paths in order to change the holding force of the holding unit. The switching mechanism switches the connection state by selecting one of the vacuum pressure supply paths and connecting the selected vacuum pressure supply path to the vacuum source.

Abstract: A support structure includes: at least two shafts extending in a first direction in which the cover expands and contracts, and arranged inside the cover so as to be spaced from each other in a second direction that intersects the first direction; a bush provided on each of the at least two shafts so as to be slidable along the shafts; and a cover support member. The cover support member includes a main part supporting the cover, a first connection part connecting the main part and the bush so as not to change the relative position between the bush and the main part, and a second connection part connecting the main part and the bush in a manner that the relative position between the bush and the main part can be changed.

Abstract: An index device of a machine tool is driven by a motor. Gap space created between the outer periphery of the motor and the inner periphery of a casing for housing the motor is filled with a material that is higher in thermal conductivity than the air. With this configuration, heat to be generated during operation of the motor of the index device is efficiently transferrable to the motor housing casing.
