Title: Color signal processing circuit
Inventor: OKABE YUKIO
IPC: H04N9/64
Filed: 1979-06-18
Abstract: PURPOSE:To apply the input to the amplifier when the color broadcast is received and thus prevent occurrence of the color noise, by installing the input signal gate circuit which is controlled by the output of the color killer circuit and the burst gate pulse between the input terminal and the 1st amplifier. CONSTITUTION:Input signal gate circuit 8 is installed between carrier chrominance signal input terminal 1 and the 1st band amplifier 2, and the burst gate pulse sent from burst gate pulse input terminal 9 is applied to circuit 8 along with the output supplied from color killer circuit 7. Then circuit 8 is opened when the color broadcast is received, and the input signal is supplied directly to amplifier 2. While circuit 8 is opened only for the burst signal output period in the case of the black- and-white broadcast, and the input signal is supplied to amplifier 2 only for the signal output period in order to prepare for the color boradcast reception. Thus the burst signal is extracted in the burst gate period and simultaneously with switching to the color boradcast. and burst gate circuit 5 is actuated, and the 2nd band  amplifier 3 is turned off via circuit 7. As a result, the occurrence of the color noise  can be prevented.

IPC: H01M10/48
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To pick up a secondary battery with abnormal discharge characteristics, to calculate the measured result for secondary batteries without any abnormal discharge characteristics, and output the average value by successively measuring the discharge characteristics of a number of secondary batteries being mass-produced. SOLUTION: Secondary batteries 1a and 1b being retained by a retaining mechanism 2 of a device 4 set a discharge starting time t to O, read a discharge voltage and a discharge current, and judge whether discharge characteristics are normal or not when a discharge is started. More specifically, data being read by a current detector 7a and a voltage detector 8a are sent to a microprocessor 11 via a multiplexer 9 and an A/D converter 10. Then, the data of discharge characteristics being used as a reference are stored at a memory 11b of the microprocessor 11 in advance and the reference data are compared with the sent measurement data by a CPU 11a. A tolerance should be, for example ±5% of the reference data. Then, when the tolerance is not met, it is judged that a measurement value is not appropriate, thus escaping from a processing flow loop.

Title: Warm water circulation apparatus
Inventor: MATSUMOTO MOTOKI
IPC: F24D3/02
Filed: 1987-03-30
Abstract: PURPOSE:To hasten warm water circulation cycle and enable return to the original condition from an air lock condition by a method wherein a valve which is installed at a circulation pipe interconnecting an open top tank and a water boiler and opened when the no-water-burning of the boiler is started, is installed and when a temp. sensor installed at an exhaust gas path connected to a combustion chamber where the boiler is, installed detects high temp., a burner is extinguished or the amount of combustion is reduced. CONSTITUTION:A valve 6 which is opened when the no-water-burning of a water boiler 3 is started is installed at a circulation pipe 5' interconnecting an open top tank 1 and the boiler 3. The boiler 3 is installed at a combustion chamber 7 and when a temp. sensor 9 installed at an exhaust gas path 8 connected to the combustion chamber detects high temp., a burner 2 is extinguished or the amount of combustion is reduced. Because of this constitution, when the no-water-burning of the boiler 3 is started, the opening of the valve 6 enables water to flow in and water vapor is therefore cooled liquefied to reduce inner pressure and the water in the tank 1 is positively forced to flow in and warm water circulation cycle can be hastened. Since an air lock condition is detected by the sensor 9 and a burner 2 is extinguished or the amount of combustion is reduced, the condition can be surely returned to the original state even if the air lock condition occurs and practical performance can be improved.

Filed: 1980-06-11
Abstract: PURPOSE: To permit stable oil-feeding even in power failure by arranging the water pressurized oil tank which communicates to a penstock and is pressurized in power failure and allowing oil to be fed into bearings by the lubricating oil which is pressurized and pushed-out by means of water pressure.  
     CONSTITUTION: A water pressurized oil tank 30 filled with lubricating oil 17 and the penstock 15 which feeds water pressure to a water-wheel 1 and has a control valve 16 bypased to the penstock 14 equipped with a hydraulic valve 13 are installed. In power failure, the hydraulic valve 13 is closed, and the control valve 16 is opened by the signal detected by the pressure switch 20 installed on the oil feeding passage to bearings 3 and 4. The water pressure in the penstock 15 increases the water pressure in the water chamber 19 of the water pressurized oil tank 30 and pushes up the lubricating oil 17, and thus oil feeding to bearings 3 and 4 is performed. Therefore, when the water wheel 1 is capable of rotation, namely in case water pressure exists, the pushing-out pressure due to lubricating oil can be secured, so stable and reliable oil feeding to the bearings 3 and 4 can be provided even in power failure.
