摘要： A wire electrode for wire-cut electrical discharge machining includes a wire composed of a core made of one of an amorphous pure metal and an amorphous alloy and a thin crystalline layer serving as a surface of the core. The wire may be coated on its surface with a layer of a material of high electrical conductivity. The amorphous alloy may be Cu-based, Fe-based, or Co-based. The use of an amorphous pure metal or alloy yields a wire electrode of much greater tensile strength than previous wire electrodes, enabling a higher machining speed.

摘要： A wire electrical feeding device for an electrical discharge machine. Vibrator assemblies are utilized to feed the wire electrode through electrode guides of the electrical discharge machine. A first vibrator assembly vibrates through a locus which includes a component in the wire feeding direction. The wire electrode is selectively pressed against the first vibrator assembly when the first vibrator assembly is moving in a direction having a component in a wire feeding direction. In the alternative, a second vibrator assembly, which is coupled to the first, clamps the wire electrode when the first vibrator assembly is moving in a direction having a component in the wire feeding direction. The vibrator assembles may each be driven at different vibrational frequencies.

摘要： A wire electrical discharge machining apparatus comprising a nozzle for a machining liquid for jetting the machining liquid from a jet hole, a surrounding member for intercepting the flow of the machining liquid jetted from the nozzle so as to prevent the machining liquid from flowing out to a portion other than the spark gap, and a holding device for holding the surrounding member so as to removably mount the surrounding member on the nozzle and so that the surrounding member does not slip off while mounted. The holding device facilitates both the operation of mounting and dismounting the surrounding member on and from the nozzle and replacement of the surrounding member. Since the surrounding member does not slip off while it is mounted, smooth preparation and working is enabled.

摘要： A machining-liquid injection nozzle unit for use in a traveling-wire EDM apparatus comprises a pair of nozzles disposed opposite to each other through a workpiece and serving to inject a machining liquid individually toward the workpiece while permitting insertion of a wire electrode therethrough in the axial direction thereof coincident with injection of the machining liquid, and a liquid screening member so shaped as to surround the axis of the wire electrode and attached to at least one of the nozzles. The liquid screening member has a low friction coefficient to the workpiece and serves to diminish the lateral force exerted on the fore end of the upper or lower nozzle due to its sliding motion, hence preventing deterioration of the machining precision. The nozzle unit further includes a piston connected to the liquid screening member and capable of producing a predetermined pressure toward the workpiece by the machining liquid in the nozzle. The piston presses the liquid screening member against the workpiece by the constant pressure despite its wear to consequently prevent leakage of the machining liquid while averting reduction of the machining speed.

摘要： A detecting electrode is mounted on the path of a thread in a sewing machine. When a cloth is sewn in the sewing machine, a bobbin thread or a needle thread moves spatially against the detecting electrode. An electric signal is obtained on the detecting electrode in response to such movement of the thread. On the other hand, a timing signal generator generates a timing signal synchronous with the vertical movement of the needle in the sewing machine. A discriminator receives the electrical signal from the detecting electrode and the timing signal from the timing signal generator. The discriminator compares the electric signal with a reference signal when it receives the timing signal and outputs a discrimination signal in accordance with the result of the comparison.

摘要： A magneto-strictive torque sensor for electrically contactlessly detecting a torque applied to a rotary shaft on the basis of a resulting change in the magnetic permeability of the surface of the shaft. Fine dents and retainer areas for retaining residual compressive stress due to the fine dents are formed on the surface of the rotary shaft. According to this arrangement, the process of magnetization resulting from the application of an exciting magnetic field and of the torque to the rotary shaft involves less magnetization due to magnetic domain wall displacement and consists principally of reversible magnetic rotation, with the result of reduced hysteresis in the magnetization process. The reduced hysteresis causes less hysteresis involved in torque detection and higher detection sensitivity, thus resulting in high accuracy of torque detection. Further, by working the surface of the rotary shaft for the purpose of forming the fine dents thereon, microdefects present on the surface layer of the rotary shaft are reduced or eliminated and thus reduced hysteresis and improved sensitivity can be attained in the process of torque detection.
