Abstract: Machining coolant/lubricant is used to operate a piston of a clamping-side coupler by feeding same via a coolant feed passage to a clamping pressure chamber through a first check valve and a clamping pressure fluid passage. The same coolant/lubricant is discharged from an unclamping pressure chamber through an unclamping pressure fluid passage and a second check valve. The resulting movement of the piston downwards brings a clamp member into contact with a workpiece to thereby clamp the workpiece on a table. Thus, a dedicated pressure source for clamping can be dispensed with.

Abstract: A multiple-bolt insertion tool in accordance with the present invention simultaneously inserts bolts into at least two bolt holes arrayed in a workpiece and includes a bolt receiving member and a hold-and-release mechanism. The bolt receiving member includes bolt positioning portions which establish a positional relationship among the bolts that are to be inserted that matches the positional relationship of the bolt holes, and a tool positioning portion, which fits (mates with) the workpiece to locate the bolt positioning portions in alignment with corresponding bolt holes in the workpiece. The hold-and-release mechanism holds the bolts in the bolt positioning portions until the tool positioning portion is mated with the workpiece and can release the bolts from the bolt positioning portions.

Abstract: A wound coil assembling jig is used to determine the length of a lead wire disposed at an end of a wound coil disposed on a stator core, and comprises a base plate and a holding device. The base plate has a mounting face mounted to an end of the stator core in an axial direction, a positioning device that positions the base plate with respect to the stator core in a circumferential direction, and an insertion opening which can receive a coil end portion, which is a portion of the wound coil protruding from the end of the stator core in the axial direction. The holding device is disposed at an outer face of the base plate, and holds the lead wire at the wound coil.

Abstract: A scooter-type motorcycle has a structure in which an article accommodation box is disposed below a rider's seat which is upward openable, and a power unit including an engine and a power transmission is disposed below the article accommodation box to be vertically swingable together with a rear wheel. The power unit is connected to a swing shaft which is disposed above a front portion of an engine crank case, and a starter motor for starting an operation of the engine is disposed above a rear portion of the crank case. An air cleaner, a suction pipe, a throttle body and an intake manifold are arranged substantially horizontally from a rear side portion of a motorcycle body towards a front side portion thereof so as to constitute an engine intake device to be connected to the engine. The throttle body is disposed between the swing shaft and the starter motor.

Abstract: A vehicle body panel having a honeycomb sandwich structure in which a honeycomb core is sandwiched between a first and a second plate includes a subhoneycomb panel formed by adhering the first plate to one major surface of the honeycomb core beforehand. The subhoneycomb panel is pressed against the second plate which is constituted by a part of a structural panel of a vehicle body with the intermediary of an adhesive layer, the other major surface of the honeycomb core being adhered to the second plate. The connection of the subhoneycomb panel to the second plate is performed after the structural panel has been connected to a strength member of the vehicle body, e. g. after a washing stage. Such a vehicle body panel with a honeycomb sandwich structure is achievable without resorting to any substantial modification of an existing vehicle body assembly line.
