摘要:
A machine tool is provided having a spindle mounted for movement in a direction parallel to the spindle axis, the Z direction, and a direction perpendicular to the spindle axis, the X direction. The machine tool includes a machine bed and has means mounted to the machine bed for supporting at least one tool. At least one spindle is rotatably supported on the machine bed and includes a chuck for supporting a workpiece. The machine tool includes means mounting the spindle to the machine bed for movement in the Z direction and for independent movement in the X direction. Accordingly, the workpiece supporting means may be moved proximate to the tool supporting means and the workpiece may be engaged by a tool. The machine tool may further include feeder means for feeding bar stock to the workpiece supporting means so that the bar stock may be engaged by a tool. The machine tool may also include workpiece transfer means for facilitating the transfer of workpieces to and from the workpiece supporting means. A machine tool system embodying the machine tool also forms a part of the invention and includes a plurality of machine beds, each having a spindle and means mounting the spindles to the machine beds for moving the spindles in the Z and X directions. An associated method is also disclosed.

A recording/reproducing apparatus with an editing function delivers a control command to a tape running servo through a system controller of a system control system at the time of phase adjustment, thus to control a capstan motor. At this time, servo status information is delivered from the capstan motor to the system controller through the tape running servo. Whether or not adjustment of tracking is completed is judged in accordance with the above information to automatically carry out adjustment of tracking, thereby making it possible to automatically conduct, at the time of editing, adjustment of tracking, which was carried out by manual operation prior to editing work, without supplementing a new circuit.

A process for producing a urethane-modified polyisocyanurate foam comprises mixing a polyisocyanate component, a polyl component containing an aromatic polyester polyol, a catalyst, a foaming agent, a surfactant and other additives under high pressure in a mixing head and then spraying the resultant mixture to expand the foaming ingredient therein. The process uses, as the catalyst, at least three compounds of N,N',N"-tris(dimethylaminopropyl)-S-hexahydrotriazine, an alkali metal carboxylate and a lead compound in combination.

A method of manufacturing a motorcycle radiator comprising the steps of:(1) arranging between a pair of horizontally arranged water tanks or headers, a straight radiator core comprising in combination: a plurality of corrugated sheets spaced alternately with a plurality of flattened tubes; the flattened tubes; and elongated reinforcing plates, each of said reinforcing plates being provided with a plurality of slits extending from opposite edge portions in width directions of the reinforcing plates, the slits on one of the opposite longitudinal edge portions being disposed in a row and at a predetermined pitch, and the slits on the other of the opposite longitudinal edge portions being disposed in another row and at the predetermined pitch at respective positions halfway between positions of adjacent ones of the slits on the one of the edge portions with respect to a direction parallel to the longitudinal axis;(11) assembling and brazing these main components to produce a straight radiator which establishes the integrity in its construction; and(111) bending the straight radiator in a direction perpendicular to a longitudinal direction of the flattened tubes so as to produce an arc-shaped radiator.

A shield for a motor scooter to protect the front legs of the operator. The shield includes extension panels pivotally mounted about hinges to the upper front panel. The extension panels may be oriented to assume multiple positions which can selectively remove the panels from the windstream, direct additional air toward the rider and provide additional shielding against air flow. Hinge mechanisms including oblong hinge pins are employed to provide various stable positions for the extension panels.

A vehicle wheel including a rim, a hub, and a plurality of spoke plates connecting the rim and hub together. Each of the spoke plates comprises a pair of axially opposite plate members each including a pair of marginal edge portions turned at an angle to the plane of a web of the plate member, and directed away from the turned marginal edge portions of the opposite companion plate member. The turned marginal edge portions serve as reinforcing ribs for the spoke plates to thereby increase the mechanical strength and rigidity of the spoke plates.

An optical-path-switching apparatus according to the present invention includes a reducing optical system capable of guiding signal light and control light along the direction of gravity into a thermal-lens-forming optical element having an incidence plane positioned to be perpendicular to the direction of gravity in such a way as to differentiate respective convergence points in a direction perpendicular to the optical axis. The apparatus further includes a light-receiving unit configured to converge or condense straight-traveling signal light in the absence of irradiation with the control light and signal light whose optical path has been switched due to irradiation with the control light using the same optical element. Further, the apparatus includes a wedge-type prism provided at a passing position of the optical-path-switched signal light to increase the distance between the optical axis of the optical-path-changed signal light and the optical axis of the straight-traveling signal light.

An ultrasonic trimming apparatus is composed of an articulated robot, a cutting apparatus, and a grindstone. The cutting apparatus is composed of an ultrasonic oscillator supported by the end portion of the robot, a cutter blade which is supported by the ultrasonic oscillator, and a workpiece securing portion which secures a workpiece. The grindstone is disposed within the movable range of the cutter blade driven by the robot and is placed in a position at which the cutter blade can pressure contact the cutter blade. The cutter blade is ultrasonically vibrated by the ultrasonic oscillator and is ground while being pressed against the grindstone by means of the articulated robot. The ultrasonic trimming apparatus efficiently cuts a sheet material composed of soft material such as plastic, fabric, or rubber, a composite material, or a material containing glass fiber even when the material has a three-dimensional shape.
