摘要： When a cylindrical single crystal ingot terminating in generally conical parts at the opposite ends thereof is machined with a cylindrical grinder which is adapted to support the ingot in place by fastening the conical parts of the ingot to a spindle side chuck and a tailstock side chuck severally provided with a conical hole and grind and finish the cylindrical part of the ingot while keeping the ingot driven on the spindle side, the ingot is liable to produce idle rotation possibly to the extent of disrupting the grinding work. A device for preventing the ingot from producing this idle rotation is provided which comprises revolution number detecting means adapted to be fastened to the tailstock side chuck and consequently allowed to detect the revolution number thereof, pressing means for pressing the ingot in the axial direction thereof through the medium of the tailstock side chuck, and control means adapted to compare the revolution number of a spindle with the revolution number found by the revolution number detecting means and effect due control of the pressing means when the difference between the two revolution numbers surpasses a prescribed threshold. The due control effected by the control means is utilized additionally or exclusively for the purpose of stopping the driving on the spindle side in one modified embodiment.

摘要： The open end of the nozzle 42 is positioned close to and facing the surface of the metal base 20 on the side were the portion of the semiconductor ingot is to be cut off. An electromagnetic valve 46 is provided in the passage through which compressed air is supplied to the nozzle 42. The initial position of the blade 19 is detected by the detector 50U and the counter 52 measures the distance the blade 19 travels downward from the detected position and then the comparator 56 detects the point at which the measured value matches the value set on the numeric value setting device 54. The electromagnetic valve 46 is opened to emit compressed air from the nozzle 42 after this detection, until the detection of the lower limit position of the blade 19 by the detector 50D. This compressed air travels along in the direction of the rotation of the metal base 20 to enter the notch of the partially cut portion of the semiconductor ingot 10 made by the inner circumference cutting edge 22 and to consequently blow out the liquid coolant present between the metal base 20 and the semiconductor ingot 10.

摘要： An azimuth regulating mechanism is provided which can easily perform the azimuth regulation with an increased precision after a carriage including a magnetic head mounted thereon has been fixed to the frame of a floppy disc drive. The carriage is slidably supported by a guide rail which is firmly held against fixing pins on the frame by means of a guide rail holder. One of the fixing pins is in contact with an eccentric portion formed on the guide rail. When the guide rail is rotated, it can be finely regulated in the horizontal direction to regulate the azimuth angle of the head on the carriage.
