    摘要: A position control system for controlling a motor-driven mechanism capable of occupying a plurality of specified positions comprises a plurality of switches for specifying a position to be occupied by the mechanism and an encoder for generating a specified position signal representative of the specified position and a loading circuit for providing a present position signal representative of the position presently occupied by the mechanism. A read-only memory circuit uses the specified and present position signals to provide a control signal for controlling the motor to move the mechanism to a particular position and a comparison signal and a particular position signal indicative of that particular position. A position detector responsive to the position of the mechanism provides a detection signal representative of the particular position when the mechanism reaches it. A comparator compares the comparison signal from the memory circuit with the detection signal and provides a match signal to the loading circuit when they coincide. In response to the match signal the loading circuit loads the particular position signal into the memory circuit as the present position signal. If the particular position signal matches the specified position signal, the memory circuit provides a control signal that stops the motor. If the particular position does not match the specified position signal, the memory circuit provides a control signal to actuate the motor again. The illustrated embodiment of the system provides a tape recording and reproducing apparatus with four different operating modes.

    摘要: Carbon dioxide is supplied from a carbon dioxide cylinder (15) to a pressure vessel (13) through reducing valves (18 and 19). The pressure vessel (13) is also supplied with a sodium hypochlorite water solution having a desired concentration through a material supply pipe (12). The material supply pipe (12) is connected to first and second branch pipes (100 and 101) through a distribution valve (102). The sodium hypochlorite water solution supplied through the material supply pipe (12) is partially sprinkled to a gas-phase region in the pressure vessel (13) through the first branch pipe 100, while the remainder of the sodium hypochlorite water solution is supplied to a liquid-phase region in the pressure vessel (13) through the second branch pipe (101). The pressure vessel (13) is provided with a liquid level retention mechanism (25 to 29) is provided to retain the liquid level in the pressure vessel (13) within a constant range. Sterile water produced in the pressure vessel (13) is delivered through a discharge pipe (31) incorporating a throttle valve (42). The pH value of the sterile water is detected by a pH sensor, and the distribution valve (102) is controlled until the detected pH value coincides with an intended pH value.
