Title: Uhf electronic tuning receiver
Inventor: SHISHIDO TSUTOMU
IPC: H03J3/18
Filed: 1982-08-06
Abstract: PURPOSE:To improve the image suppressing ratio over the entire receiving range, by providing an image trap where the frequency is shifted together with a tuning frequency to an interstage coupling circuit. CONSTITUTION:A UHF electric tuner is constituted with a high-frequency amplifier circuit 3, the interstage coupling circuit 5 and a mixing circuit 7. The interstage coupling circuit 5 is provided with a resonance circuit comprising a capacitor 53, a coaxial resonance line 5 and a resonance frequency varying varactor diode 59. A coupling loop 57 leads a signal of the resonance circuit to the mixing circuit 7. The image frequency is synthesized at an opposite phase by coupling a coupling loop 7 and an input section of the resonance line 55 with a capacitor 50 in the electronic tuner constituted like this. Since the trap frequency through the constitution changes in follow-up to the change in the tuning frequency, the image frequency is improved over the entire receiving band of UHF.

Title: Error display device
Inventor: AONO FUMIO
IPC: G06F11/34
Filed: 1989-05-31
Abstract: PURPOSE:To specify a position where an error occurs first by dividing error display elements into plural groups and suppressing the setting of the other error generation group display element in response to the setting of one error generation group display element. CONSTITUTION:When an error occurs in the device, the error is detected by an error detecting circuit 2.n at first and then an error signal is set up in an error displaying FF 2.2n. On the other hand, the occurring error is propagated in the device and induces a new error, which is detected by error detecting circuits 2.2, N.2 and the output of the error detecting circuit 2.2 is reached to an AND gate 2.12, but the setting of the output to an error displaying FF 2.22 is suppressed. On the other hand, the outputs of two error displaying FFs 2.2n, N.22 are reached to the input of an error displaying FF respectively as error occurrence display signals 101, 102, but when the first arriving signal 101 is set up in the FF 22, the entry of the succeeding signal 102 is suppressed. Consequently, the cause of a fault can be specified.

Abstract: PURPOSE:To separate a system of an electric equipment between redundant systems, by connecting an operating machine and a stand-by machine by an optical fiber cable, and transmitting a start signal of the stand-by machine by a trip of the operating machine, by an optical signal. CONSTITUTION:When a breaker 52B of a transmission side control panel 100 is opened by a trip of an operating machine, a contact (a) of a relay 52BX is opened, and a contact (b) 23 is closed. As a result, a relay LBY and a timer LBT are energized and an output of a light emitting device 27 becomes ''0''. After a constant interval of time, when the timer LBT is counted up, a relay LBX is released, and an output of the light emitting device 27 becomes ''1''. A control panel 200 of a stand-by machine receives signals of ''0'' and ''1'' by optical fiber cables 29, 30, and a photodetector 31 applies an opening and closing signal to a relay KA. At the same time, a timer KT starts counting, and in case when ''1'' is not received even when a constant interval of time passes away, it is decided to be a stand-by start. In this way, it is possible to cope quickly and exactly with a trip of the operating machine.

Title: Scale-dissolution method
Inventor: ONO YUUICHI
IPC: C02F5/08
Filed: 1993-05-17
Abstract: PURPOSE:To easily judge the ending point of scale removal without stopping the operation of cooling water system by a method wherein, after addition of acidic scale-dissolving agent to the corresponding circulating water system, the pH of circulating cleaning liquid is measured and, when the pH reaches a predetermined value, the cleaning is stopped. CONSTITUTION:When scale forms or sludge precipitates on the heat transfer surface of a boiler or cooling water system, the acidic scale dissolving agent having a pH of at most 7, preferably 3-5, and a dissolution capacity for calcium carbonate, e.g. chelating agent such as ethylene-diaminetetraacetic acid and nitrilotriacetic acid, sulfuric acid and high-molecular scale dissolving agent, is added to the corresponding circulating water system. Although the pH of the circulating water falls temporarily by the addition of this acidic scale dissolving agent, since the PH rises as the dissolved scale (calcium carbonate) increases with the progress of cleaning the scale removal is judged as being complete to stop the cleaning when the pH of the circulating water is measured and the measured result reaches a predetermined value.
