Title: Four-channel stereophonic demodulator
Inventor: OOKUBO TSUNEO
IPC: H04H20/89
Filed: 1979-08-20
Abstract: PURPOSE:To separate four audio signals completely while reducing the disturbance of an SCA broadcast signal by use of an SCA filter, by providing a phase correcting circuit to a detecting method for the 3rd subchannel signal in a four-channel stereophonic demodulator. CONSTITUTION:To input terminal 1, a four-channel stereophonic composite signal is applied which consists of the main channel signal, the 1st subchannel signal, the 2nd subchannel signal, the 3rd subchannel signal, and a 19kHz pilot signal. Since the frequency band of the 3rd subchannel signal overlaps with that of an SCA broadcast signal, only the main channel signal and the 1st and 2nd subchannel signals pass through SCA filter 3 and the 3rd subchannel signal passes through phase correcting circuit 4. For this purpose, phase correcting circuit 4 corrects the phase shift of the main signal, etc., from the 3rd subchannel signal generated when it passes through SCA filter 3, and consequently a phase shift among four channel signals never appears in detection, so that four audio signals can completely be separated.

Title: Traffic control system
Inventor: ATOZAWA SHINOBU
IPC: H04L12/00
Filed: 1989-04-26
Abstract: PURPOSE:To eliminate the need for monitoring processing for a traffic at a relay line adaptor and to improve the throughput of a device by controlling the traffic of the realy line adaptor based on the traffic information of a terminal line adaptor. CONSTITUTION:The data transfer operation is the same as that for a conventional technology. The traffic control task 8 of a terminal line adaptor is started periodically at the transfer and its own traffic information is reported to a device management section 3. The traffic management task 11 of the management section 3 analyzes the traffic information of each terminal line adaptor 1 and gives an input regulation command to control the traffic flowing from the line to the traffic control task 8 of the relay line adaptor 2 and each terminal line adaptor 1 when the traffic quantity on the relay line adaptor 2 exceeds a prescribed quantity, analyzes the traffic information consecutively and gives an input regulation releasing instruction when the traffic quantity is less than a prescribed quantity. The traffic control task 8 applies input regulation/release by the instruction of the traffic management task 11. Since the traffic control has only to be implemented with the presence of the instruction, the throughput is improved.

Abstract: PURPOSE:To eliminate a boiling state of circulation water and reduce noise by a method wherein an extreme end of a hot water pipe of a hot water heat exchanger is spaced apart above a water surface of a sub-tank, opened freely expanded or retracted and immersed below the water surface of the sub-tank when a circulation pump is operated. CONSTITUTION:An extreme end 9a of a heat pipe 9 is of a belows type or a double- pipe and can be expanded or retracted in a vertical direction. When the pipe is extended downwardly, the opening of the extreme end 9a is immersed in the sub-tank 19 and in turn when the pipe is retracted upwardly, the opening is spaced apart upwardly from the water surface 19a. When a hot water heating operation is set, heating water (hot water) for use in heating operation is flowed in the hot water pipe 9 with a circulation pump 20. This water is heated to become hot water, the hot water flows from the sub-tank 19 and the circulation pump 20 through a hot water outer 21, is returned back to a hot water return port 18 and circulates. Water flowing from the hot water pipe 9 toward the sub-tank 19 does not generate any sound, but flows toward the sub-tank 19. In the event that the hot water heating operation is not carried out, water in the hot water pipe 9 drops into the sub-tank 9 due to a difference in the head and the pipe is vacated.

Abstract: PROBLEM TO BE SOLVED: To lessen the number of an ON and OFF frequency of a pressure pump in an area where water supply is suspended or the water pressure is low, shorten the water purifying time, and prevent noise generation due to ON and OFF switching of the pressure pump and wear of the parts by sensing the pressure of source water and controlling the operation of the pressure pump based on the water pressure fluctuation. SOLUTION: The water level of a purified water tank is sensed by a water level sensing means 105, the water level data is sent to a controlling means 110, and in the case the water level in the purified water tank is judged to be water shortage level or lower, a water supply valve 57 is opened. At that time, the pressure of source water supplied to a water supplying pipe from a tap water faucet is sensed by a water pressure sensing means 115 and sent out to the controlling means 110 to judge whether the pressure of the source water is the normal water pressure or low water pressure or whether water supply is suspended or not. In the case that suspension of water supply is judged, the pressure pump 59 is stopped.  Meanwhile, the pressure of source water is determined to be the normal pressure or low pressure, the pressure pump 59 is driven and the pressure of the source water is elevated to a prescribed pressure and the water is passed through a membrane, so that various kinds of heavy metals, carcinogenic substances, microbes such as bacteria contained in the source water can be removed.
