Abstract: PURPOSE: To efficiently obtain a highly flat semiconductor wafer by simultaneously polishing both surfaces of the wafer after the wafer is obtained by slicing an ingot and the peripheral edge section of the wafer is chamfered and specular finishing the surface of the wafer, and then, cleaning the wafer. CONSTITUTION: After a wafer 1 is obtained by slicing an ingot, the peripheral edge section of the wafer 1 is chamfered and the cut face of the wafer 1 is flattened by lapping. Then, the lapped wafer is put in the retaining hole 21 of a carrier 2 and the carrier is held between a lower polishing plate 3 carrying polishing cloth 4a fixed to its upper surface and upper polishing plate 4 carrying polishing cloth 4a fixed to its lower surface by pressing the plates 3 and 4 against the carrier 2. While the carrier 2 is held between the plates 3 and 4 in such a state, both surface of the wafer 1 is simultaneously polished by rotating the plates 3 and 4 in the opposite directions. After polishing both surfaces, one surface of the wafer 1 is finished to a mirror surface and, finally, the wafer 1 is washed. Thus a highly flat semiconductor wafer can be obtained efficiently.

Title: Magnetic recording and reproducing device
Inventor: YOSHIOKA ISAYUKI
IPC: H04N5/91
Filed: 1992-04-02
Abstract: PURPOSE:To suppress the power consumption of a magnetic recording and reproducing device by stopping the reproduction function of a signal corresponding to an FM voice signal at the time of the reproduction of the FM voice signal and permitting a normal voice signal to be selected. CONSTITUTION:When the reproduction of the FM voice signal is selected and the FM voice signal with a high faithfullness degree is not recorded in a reproduction tape or the carrier level is low with noise in a demodulation voice signal, a control circuit 11 automatically selects the normal voice signal with a control signal outputted from a carrier wave detecting circuit 10 and outputs it even when the FM voice signal with the high faithfullness degree is selected by an external control signal from a terminal 51. In this state, L and R channel FM demodulating circuits 6, 7 and L and R channel NR decoders 8, 9 are not required. It is same when the normal voice signal itself is selected by the control signal. Therefore, a power source to be supplied to an unrequired circuit element is turned off with control action by the circuit 11 so that extra power consumption is suppressed.

Abstract: PURPOSE:To obtain the maximum torque transmission effect that a diameter of a rotor can produce and to reduce an exciting coil to small size by forming flanges on both sides of a poly-V-groove pulley, the side of one flange being used as a friction surface. CONSTITUTION:When an exciting coil is energized, magnetic flux phi is generated in a magnetic path indicated by a broken line, and an armature 6 is adsorbed to a rotor 3 against the elastic force of a leaf spring 7, so that the turning force of the rotor 3 is transmitted to a driven shaft through the armature 6, the leaf spring 7 and a boss 8.
