Title: Logic circuit
Inventor: WAKIMOTO AKIHIKO
IPC: H03K17/22
Filed: 1979-12-13
Abstract: PURPOSE:To prevent malfunction by initializing the whole system when the minimum value of an operating power voltage is less than a guaranteed value. CONSTITUTION:Reference voltage generating circuit 13 generates a voltage of a value that does not depend upon a power voltage. This voltage is set to threshold voltage VX of inverter 16 to the maximum value of operating power voltage margin K of the control system. When the power source is put to work, initializing signal generating circuit 20 operates to hold the output of NAND 17 at level ''H''. Then, if the generation of the initializing signal ends and the power voltage is within the margin, the output of inverter 16 is held at ''H'' without fail and two inputs to NAND 17 are both at ''H''. As the power voltage exceeds the margin, the output of inverter 16 drops down to level ''L'' and during the period, initializing signal 19 is held at ''L''.

Title: Pulse counter
Inventor: TAKESHITA TORAO
IPC: H03K21/02
Filed: 1986-07-10
Abstract: PURPOSE:To obtain a position detection signal with a high speed and high accuracy by counting the input of 2-channel being coarse and accurate pulses independently of high-order digit and low-order digit and devising the titled counter so that the counter of the low-order digit is reset by the input pulse of the high-order digit counter. CONSTITUTION:If the high accurate pulse frequency is very high, the content of a high accuracy pulse counter 4 constituting low-order digit is inaccurate depending on the distortion of a high accuracy pulse wave-form or the response of the counter, but since the accumulated count is set to zero by a leading signal of a coarse pulse, no accumulated error is caused. If the high accuracy pulse frequency is decreased to a prescribed value or below, the accurate pulse counter 4 is operated normally and accurate count is attained by the addition with the high-order coarse pulse counter 3. Thus, the position detection with high resolution is applied and high speed position detection is attained.
