Title: Electrolytic water-producing method
Inventor: NOGUCHI HIROYUKI
IPC: C02F1/46
Filed: 1994-12-22
Abstract: PURPOSE: To lower bath voltage corresponding to a detected pH value and properly carry out bath voltage lowering control based on excessive current detection by sending out a voltage lowering order to an electric power source part corresponding to the response speed of the electric power source part. CONSTITUTION: A control circuit C with which a pH sensor 7 and a flow meter 6 are connected controls the electrolytic voltage to be applied to electrodes of an electrolytic bath 2 by PWM control of an electric power source part DV. Also, a comparison circuit C1 to compare an aiming pH value with the pH value of electrolytic water by the pH sensor 7 is built in the control circuit C and the control circuit C so controls the electrolytic voltage based on feedback as to make the detected pH value become the same as the aiming pH value. Furthermore, a comparator CP to which the voltage between both ends of a low resistance value resistor R inserted in the electric power source part DV is sent compares the intensity of the flowing electric current corresponding to the decrease of voltage of the resistor R with the upper limit value.  In the case where the flowing electric current exceeds the upper limit value, an excessive current detected signal is sent out to the control circuit C. Besides, the control circuit C sends out a voltage lowering order signal to the electric power source part as to lower the voltage applied to the electrodes.

Title: Digitized ghost image eliminator
Inventor: KIMURA KATSUNOBU
IPC: H04N5/21
Filed: 1990-11-27
Abstract: PURPOSE:To effectively and accurately eliminate an ghost by providing a delay control timing generation means setting writing timing and reading timing for each FIFO memory based on the delay time of each ghost component, and a coefficient control means controlling a tap coefficient for each transversal filter based on the amplitude of each ghost component. CONSTITUTION:When the delay time is once set by a writing signal W and reading signal R1, R2, R3 and R4, the FIFO memories output all input data while delaying by the delay time tau since then, so the delay time can be set without fail. On the other hand, a tap coefficient control circuit 115 outputs a gain control signal for adjusting the tap gain of each transversal filter corresponding to amplitude data DB outputted from a comparating arithmetic circuit 122. Each transversal filter outputs a signal canceling the ghost component for each delay time corresponding to the gain control signal. The output signal of each transversal filter is added with a digital video signal by adding means 103 to 106.

Title: Method and device for removing end of roll packing
Inventor: NOSAKA YOSHIKI
IPC: B26D1/18
Filed: 1987-12-19
Abstract: PURPOSE:To automatically remove side ends of a roll package surely by rotating the roll package, sensing the difference in the trait between the roll and the packing material by a sensor, actuating a cutting tool when the sensor has sensed the packing material, and by putting the cutting tool out of operation when the sensor has sensed the roll. CONSTITUTION:A roll package R is placed on a pair of parallel supporting rollers 1a, 1b and rotated in the direction of B, and a sensor S senses first the packing material R1, and the signal emitted actuates a cutting tool advance device 3. Accordingly the advance device 3 raises a cutting tool C which cuts into the packing material R1. Thus the cutting tool C rotating cuts the peripheral packing material R1 into rings and severs their side material R4. Thereby the sensor S senses the roll W, and the signal emitted puts the advance device 3 out of operation, and the cutting tool C retracts to go apart from the roll package R. This provides sure removal of the side ends of the roll package R without causing the cutting tool C to damage the roll W.
