Title: Controller for stepping motor
Inventor: YAMANE TAKESHI
IPC: H02P8/14
Filed: 1984-10-15
Abstract: PURPOSE:To accurately perform a rotary position command even by a command voltage 0V by comparing a position command signal with an addition signal offset from a position detection signal. CONSTITUTION:Adding means adds a position detection signal representing the rotary position of a step motor and an offset signal having the prescribed offset amount, and outputs an addition signal. Comparing means compares the addition signal with a position command signal, and outputs a comparison signal. Signal processing means outputs a rotary command signal and a rotating direction command signal to step motor drive control means in response to the comparison signal to control a step motor. Thus, even if the position command signal is 0V or near 0V, an accurate rotary position control can be performed in response to the position command voltage, and unnecessary vibration does not arise even when the motor is stopped.

Abstract: PROBLEM TO BE SOLVED: To manufacture a transmission type screen capable of inexpensively and easily keeping the flatness of the thin screen by closely fixing the peripheral part of the transmission type screen to a screen holding frame by a structure having slidability. SOLUTION: The screen 10 is fitted and fixed by the structures 11 and 12 such as metal or fluororesin which is excellent in the slidability and whose frictional resistance is small. The respective structures 11 and 12 are held by the screen holding frame 13 and the frame 13 is fitted to a television main body. Besides, an interval between a left and right parts and an upper part put of the interval between the screen 10 and the frame 13 is held by being pressed by an elastic member 14 and the elongation and contraction of the screen 10 in the vertical and the horizontal directions is absorbed.  By fixing the television main body by the structures 11 and 12 which are excellent in the slidability and whose frictional resistance is small, displacement caused by thermal expansion is deviated at a contact surface between the television main body and the structures 11 and 12 even when temperature is changed by an environment. Thus, the lenticular screen is maintained so that it is provided with the excellent flatness without wrinkles and deflection.

Abstract: PURPOSE:To obtain a static addition circuit which has a comparatively high- speed operation with easy control despite a small quantity of hardware, by providing an MOS transistor TR which sets a carry output node at a high level in case a carry is produced instead of the precharge and giving the control of conduction to said TR with a carry generation signal. CONSTITUTION:Operands A and B are not coincident with each other, that is, one of both operands is equal to '0' with the other equal to '1' respectively. Under such conditions, carry transmission signals P and -P are equal to '1' and '0' respectively. Then MOSs TR1 and TR2 are turned on. At the same time, a carry production signal -G is equal to '1' and a carry deletion signal K is equal to '0' respectively. Thus both MOSs TR3 and TR4 are turned off and a carry signal Cout corresponding to a carry signal Cin sent from the preceding stage is delivered. In this case, a signal P of an exclusive OR gate 16 is equal to '1'. Therefore the sum output S is equal to '0' as long as the signal Cin is equal to '1'. In this case, the signal Cout is equal to '1'. Then the output S is equal to '1' with the signal Cout equal to '0' as long as the signal Cin is equal to '0'.
