Abstract:
A non-contacting position detecting apparatus includes a laser unit having a light emitting portion and a light receiving portion for irradiating laser light upon a detection point of a subject for measurement and receiving laser light reflected from the detection point to recognize the distance to the detection point. An arm is capable of moving the laser unit in the direction of at least one axis of a rectangular coordinate system. A coordinate detecting member is provided for detecting coordinates of the arm. Coordinates of the detection point are recognized in accordance with the coordinates of the arm when the positional relationship between the detection point and the laser unit reaches a predetermined relationship. The laser unit includes a needle-like indicating member for indicating the crossing point between extension lines of an optic axis of laser light radiated from the light emitting portion and an optic axis of laser light received by the light receiving portion when the detection point and the laser unit reach the predetermined positional relationship.

Abstract:
The present invention relates to a choke coil utilized in a variety of electronic products both for industrial use and consumer use, and aims to provide a choke coil that is thinner in size, accommodates a larger current, provides better efficiency in assembly and higher reliability. The choke coil of the present invention comprises a closing magnetic core having a center magnetic leg, an outer magnetic leg 36 and a common magnetic yoke. A coreless coil winds a plate-type wire around the center magnetic leg of the closing magnetic core to form itself, and is mounted to the closing magnetic core. At least one terminal coupled to an inner turn of the coreless coil out of terminals coupled to both ends of the plate-type wire of the coreless coil is led out from a notch provided on one side of the common magnetic yoke of the closing magnetic core.

The interrupt test circuit is connected between the peripheral units and the interrupt controller and includes a test signal output connected to the interrupt controller, and storage means for storing an interrupt request test signal when receiving a predetermined signal and for supplying the test signal through the test signal output to the interrupt controller for interrupt performance test.
Abstract:
A skid beam for use in a walking beam type heating furnace which has operating temperature exceeding 1000.degree. C. comprises a hollow skid pipe of heat resistant alloy, skid buttons provided upright on the skid pipe and arranged axially thereof at a predetermined spacing, and a refractory lining covering the outer peripheral surface of the skid pipe and each of the skid buttons over the base portion thereof toward its upper portion. Each of the skid buttons comprises a first member attached to the skid pipe and made of a heat-resistant alloy, and a second member to be brought into contact with the material to be heated. The second member is made of a composite material composed of a heat-resistant alloy and ceramic particles dispersed therein in an amount of 30 to 70% by weight based on the composite material. The skid button has a height exceeding 120 mm. The lining portion covering the skid button over the base portion thereof toward its upper portion has a thickness so as not to give a temperature difference of 40.degree. C. between the top of the skid button and the interior of the furnace.
