A shaft having a magnetostrictive sensor measures torque applied to a shaft, as a shaft, without contact and utilizing reverse-magnetostrictive properties of magnetic alloys. The shaft includes a plurality of magnetic alloy layers, and the magnetosensitive torque detector is variously formed by diffusion bonding a magnetostrictive layer with a high magnetostrictive constant onto the shaft surface, by heat treating, adhesive fixation or the like bonding means. Methods for making the shaft are disclosed.

A rotating apparatus for orienting transformer core plates during feed to a laminating station by a conveyer. The apparatus includes a plurality of level guides disposed at spaces between each of plural spaced conveying belts of the conveyer, the level guides including top ends which rise above an upper surface level of the conveying belts while the plate is lifted and rotated by rotating device, and descend to below the upper surface level of the conveying belts when the plate is translated by the conveying belts after the rotation, so that the plate rotates to slide on the level guides.

A mass flow sensor is capable of accurately measuring a mass flow irrespective of changes in the ambient temperature. The mass flow sensor includes at least one heating resistor disposed on a portion of a sensor pipe through which a fluid to be measured flows and a housing for the sensor pipe. The heating resistor and a temperature sensitive resistance constitute a bridge circuit. The temperature sensitive resistance is disposed in the housing. The resistance of the sensor changes in accordance with the change in the temperature of the housing to thereby adjust the change in the resistance of the heating resistor. Further, an improved temperature sensitive matching resistor is suitably used in the mass flow sensor, in which a plurality of temperature sensitive resistances having equal characteristics are integrated.

A fluid flow control valve includes a valve disk having a labyrinthine partition extending from its face. The partition describes a closed shape. The partition faces a valve seat. The range of control over the flow rate of a fluid is controlled by the length of the partition. Partition lengths are created by their shapes. Several complex shapes, giving rise to differing partition lengths are disclosed. An actuator urges the valve disk toward the valve seat to provide final control of the fluid flow.

An optical fiber fusion splicer includes a discharge unit for producing an electric discharge to fusion splice optical fibers and a pressure sensor for producing a pressure detection signal representing the surrounding atmospheric pressure. In response to the pressure detection signal the discharge is controlled by a control unit so that a substantially optimum discharge current for the fusion splicing is provided to the discharge unit. The discharge control unit includes an adjusting unit for producing a discharge current adjusting signal, a control signal generating unit for generating a control signal on the basis of both the pressure detection signal and the discharge current adjusting signal, and a discharge current control unit for controlling the discharge current in response to the control signal.

A rectangular pattern recognition device is disclosed which operates to recognize and note the position of solid-line rectangles drawn on an input form, document, or the like. The apparatus first recognizes vertical and horizontal line segments and then discriminates the areas which lie within the joined segments. The device may further be provided with code or symbol recognition means which can discriminate symbols, e.g. an optional numbering of the rectangles from the other line segments forming the rectangles.

A method for manufacturing an information memory disk comprises a process for preparing a die having an annular first rugged portion corresponding to tracks, and an annular second rugged portion corresponding to a positioning mark and concentrically located against the tracks, a process for manufacturing by the use of the die a blank having an annular rugged tracks corresponding to the first rugged portion and an annular rugged positioning mark corresponding to the second rugged portion, a process for detecting the position of the center of the blank on the basis of the positioning mark, a process for boring a hole centering around the center of the positioning mark through the blank, and a process for forming a light reflecting layer on the annular rugged track.
摘要:
A programmable sequence controller wherein in accordance with a sequence program read out from a memory, a logic operation circuit tests a logical value supplied from an input converter connected to an external input element and generates an output command signal based upon the result of the test. The output command signal is stored in an output memory which has two storage addresses for each external output element, each storage address corresponding to a particular memory storage element addressed by the sequence program. A gate circuit is connected to these two memory storage elements and inhibits the application of an output command signal from one of the memory storage elements to an output converter when the gate circuit receives a logical value from the input converter. When receiving an output command signal from the other of the two memory storage elements the gate circuit then applies this signal to the output converter. Thus, an output element connected to the output converter is energized immediately in response to the operation of an input element.

A combined load-sensing proportion and relay valve for an air brake system including a valve disk which has an exhaust passage in its axial center and is adapted to hold the valve in normally closed position, and a control piston unit which is actuated by an indicated pressure from a brake valve to move the valve disk and open the valve. The control piston unit includes a first pressure-sensing piston for controlling the valve-opening action of the valve disk and a second pressure-sensing piston coaxially connected to the first piston via a spring therebetween. A stroke adjusting device is provided to control the axial movement of the second piston correspondingly to the payload of the vehicle.
