Filed: 1982-01-29
Abstract: PURPOSE:To enable the control of a plurality of objects to be controlled with one timer by on/off control of a plurality of switches corresponding to a value of each bit in a word, read out of a memory one address at a time sequentially for a certain time. CONSTITUTION:An output pulse of an oscillator 2 is counted with a pulse counter 3 to integrate. An arithmetic unit 4 determines that an on/off signal of a switch will correspond to such and such bits at such and such an address of a memory 5 and writes it into the memory 5. The memory 5 is allowed to write and read a signal to turn on or off the number of switches corresponding to the number of bits per one word. A control section 6 reads a binary data at an address of the memory 5 as specified by a value of the counter 3 each time the value varies and converts the bit value thereof into an on/off signal for individual switches to control a switch group S.

Abstract: PURPOSE:To enable the detection of alignment marks with high accuracy, by detecting the marks at a position separated from a transfer image by a prescribed distance L, and by moving an exposure substrate by a value determined by the sum of the size of the exposure substrate and L. CONSTITUTION:After a reticle R is put on a reticle stage 3, the stage 3 is positioned so that the reticle R be at a prescribed position in relation to the optical axis AX. Marks Mx, My and Mtheta are detected by an optical system 20.

Title: Switched reluctance motor
Inventor: KURIHARA HIROYUKI
IPC: H02K7/02
Filed: 1997-01-10
Abstract: PROBLEM TO BE SOLVED: To reduce torque ripple to a minimum and restrain vibration and noise due to vibration, by fixing a flywheel having a suitable mass to the rotating shaft side of a rotor. SOLUTION: A disc-shaped flywheel 3 having necessary mass is fixed to a rotating shaft to which a rotor 1 is fixed. Torque ripple (rapid drop of torque) which is caused by mismatch of the number of magnetic poles of the rotor 1 and a stator 4 is compensated by the moment of inertia of the flywheel 3, so that smooth rotating operation is always realized. Since the rotating operation is maintained by using the inertia momentum of the flywheel, power-saving also can be realized by performing the ON/OFF control of power supply operation to a motor at suitable intervals. Thereby vibration and noise can be effectively prevented, and a motor of high quality and high output wherein the rotating operation is stable can be obtained.
