Title: Cross polarization interference elimination device
Inventor: KANEKO ICHIRO
IPC: H04J11/00
Filed: 1997-04-30
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of step-out of its own polarized wave by detecting the cross polarization interference value of its own polarized wave and outputting a 3rd reset cancel signal when the detected interference value exceeds the pull-in point set in a stop state of a cross polarization interference elimination function, thereby stopping the resetting action applied to its own polarized wave and performing the pull-in via the maximum capability of a cross polarization interference eliminator. SOLUTION: Cross polarization interference value detectors 115 and 116 input the compensation signals outputted from the outputs of transversal filters 109 and 110 in response to the cross polarization interference value and then output the reset cancel signals 19 and 20 when the cross polarization interference value exceeds the pull-in/step-out point set in a stop state of a cross polarization interference elimination function. The resetting circuits 111 and 112 receive the signals 19 and 20 and never reset the filters 109 and 110. As a result, the step-out states of both V and H polarized waves can be decreased and one of cross polarization interference eliminators 5 and 6 is operated to keep the satisfactory circuit quality.

Inventor: NISHI YOSHIO
IPC: H02M7/48
Filed: 1988-05-09
Abstract: PURPOSE:To detect the malfunction of an apparatus surely by monitoring the mean value of electric current on the AC transformer secondary side. CONSTITUTION:AC is converted by a converter apparatus into DC and then into AC output current at a desired frequency by the switch operation of each thyristor of an inverter apparatus.

Filed: 1997-04-14
Abstract: PROBLEM TO BE SOLVED: To obtain a heat storage mechanism having high heat storage capacity which can be installed even in a limited space and can utilize energy at high efficiency by arranging polyethylene glycol encapsulated in an enclosed container in a heat storage bath and in which the heat storage capacity can be varied freely by adjusting the number of the enclosed containers. SOLUTION: Liquid in a hot water storage tank 1 is fed into a heat pump 2 where it is heated up and circulated while being kept at about 55 deg.C. The heated liquid in the hot water storage tank 1 is fed to a heat-exchanger 3 in order to transfer heat to a fluid being Fed into a heat storage bath 4. The heat storage bath 4 is internally subdivided into six subsections for storing water and polyethylene glycol encapsulated in an enclosed container. Since polyethylene glycol has heat storage capacity about 35 times as high as that of water, heat storage effect is enhanced as compared with a case employing only water. Cooling liquid of 14 deg.C or below is stored in a cooling liquid tank and fed to a heat pump 7. During normal automatic operation, temperature of liquid in the heat storage bath 4 is set at 10-12 deg.C for cooling operation and at 40-45 deg.C for warming operation.
