Filed: 1988-03-02
Abstract: PURPOSE:To secure the reliability and to reduce the cost by constituting a controller used only for a short time at the time of start, etc., as a single system and constituting controllers used at the time of continuous operation as dual systems. CONSTITUTION:A controller 3 for start is used only at the time of starting a plant. Controllers 4 and 5 for continuous operation are used at the time of continuous operation of the plant.

Title: Echo preventing loudspeaking device
Inventor: TSUKUI AKIHIKO
IPC: H04M9/08
Filed: 1981-03-31
Abstract: PURPOSE:To prevent the echo, by always adding the reference signal having a certian spread of frequecy to the driving side of an electro-acoustic transducer to extract the reference signal entered the electroacoustic transducer and then detecting the degree of acoustic coupling to erase the reference signal entered the transducer. CONSTITUTION:The aural signal supplied through a telephone receiver terminal 7 is amplified 8 and 9 to be delivered through a speaker 2. The voice, etc. supplied through a microphone 1 is delivered through a transmitter terminal 6 via amplifiers 4 and 5. A reference signal generator 10 produces the signal BG music, etc. having a certain frequency spread to add it to the amplifier at all times and then to deliver it throuth the speaker 2 in the form of a sound wave. This sound enters the microphone 1 to be extracted by a detector 11, and the amplitude and the phase are compared with the reference signal 10 through a comparator 12. As a result, a tap gain controller 14 is controlled to control the tap output signal of a delay circuit 13. Thus the signal corresponding to the entering characteristics is erased. As a result, the coupling state is detected to erase the entered signal although the environment varies.

Title: Indirectly-heated cathode for fluorescent character display tube
Inventor: KATAUE KANJI
IPC: H01J31/15
Filed: 1986-03-04
Abstract: PURPOSE:To reduce the production cost, by composing a cathode, of a heater forming an alumina insulator layer over a heater core, metallic microwires wound over the heater, and an electron radiating substance spread over them. CONSTITUTION:A heater 3 consists of a heater core 1 of tungsten and an alumina insulator layer 2. Over the heater 3, tungsten wires are sound closely to form a cathode base 4 of metallic wires. In this case, the tungsten wires are wound closely from one end of the heater where the alumina insulator layer 2 is not applied, and the cathode base 4 and the heater 3 are connected electrically. Over the cathode base 4, an electron radiating substance 5 is spread and the both 4 and 5 form a cathode 6. The indirectly-heated cathode 6 does not use a tube-form substance as the cathode base like this. Therefore, a difficult work to penetrate a heater 3 in a small tube is not necessary. The production cost can be reduced consequently.
