Abstract: In a slide actuator, a central guide rail having V-shaped grooves defined therein and opened at 90 degree angles, is mounted on a cylinder body. A slide table is brought into engagement with the guide rail. Guide members having V-shaped grooves defined therein are provided inside the slide table so that they are opposed to the grooves defined in the guide rail. Cylindrical roller bearings are alternately fitted at inclinations of 90.degree. in their corresponding channels defined by the opposed grooves. Thus, when the roller bearings are rolled, the slide table is displaced with higher accuracy and a load supported by the slide table is transmitted to the guide rail from the roller bearings.

Abstract: A tool fastening apparatus for industrial robots comprises a coupling unit attached to the arm of a robot and a coupling unit attached to a tool to be used with the robot. When the two coupling units are joined together, their relative position can be easily and accurately fixed by means of positioning couplings comprising ball rings carrying a set of annularly arranged balls slightly sticking out from the plane of contact between the two coupling units. Accurate positioning is achieved by bringing the balls on the two ball rings into engagement, which, in turn, is achieved by fitting each ball on one ball ring into between two adjoining balls on the other ball ring.

Abstract: In this parallel gripper suitable for gripping a work for a robot or the like, in which a pair of fingers are opened and closed by keeping the parallel condition between them by the transmission of the driving force of a fluid pressure actuator to the fingers by means of a power transmission mechanism, use is made of a pair of pistons, that are relatively slidable in a single cylinder bore under the action of fluid pressure, as the fluid pressure actuator, thereby obtaining substantially twice as large gripping force as in the case of empolying a single piston.

Abstract: A coil of tapered wire for forming coil springs, formed by winding substantially in concentric loops a quench-hardened and tempered tapered wire having a successive arrangement of tapered wire segments each consisting of a thick section, two thin sections and two tapered sections connecting the thin sections to the opposite ends of the thick section, respectively. The tapered wire is subjected to a preforming action immediately before being wound in loops on a winding drum, to form plastic bends in the thick sections and plastic bends of a radius of curvature greater than that of the plastic bends in the thick sections so that the tapered wire is wound in substantially uniform, concentric circular loops on a winding drum.

Abstract: An automatic on-off valve for use with a pneumatic micrometer connected between the main body of a pneumatic micrometer and its measuring head for economizing the consumption of pressurized air includes a valve body having, between an inlet and an exit thereof, a main flow passage to be opened and closed by a valve member and a sub-flow passage always open with a slight gap. The valve member is automatically turned on or off by the back pressure difference at the measuring head between a measuring state and a not-measuring state. The total open cross sectional area for both of the flow passages are set to be 6 to 9 times as large as the cross sectional area for a flow passage which is formed between a nozzle of the measuring head and an object to be measured upon the object being placed to measure the maximum gap, whereby a measuring error resulting from the disposition of the automatic on-off valve can be minimized within an allowable range to thereby maintain the measuring accuracy a desired high level.

Abstract: A Josephson logic gate device comprises a closed loop of four Josephson junctions, a gate line and a ground line connected to the closed loop at symmetrically opposite points, and a control line connected to the closed loop at the intermediate joint between the gate line and ground line. This logic gate produces a switching function in which the gate current fed to the gate line is steered from the gate to the load by the transition between the zero-voltage state and the voltage state of the device when a control current is supplied into the control line.
