Inventor: OKOCHI TOSHIHIRO
IPC: F23C99/00
Filed: 1995-09-14
Abstract: PROBLEM TO BE SOLVED: To achieve a higher heat efficiency while preventing the generation of soots within a burner by a method wherein water or steam is added to a fuel gas when a hydrocarbon based gas is burned in a combustion furnace and the fuel gas is reformed by preheating thereof to perform a combustion. SOLUTION: In a combustion furnace 1, a combustion exhaust gas in the furnace 1 is sucked during the storage of heat to pass through an air heat storage body 2 for combustion to store heat in the air heat storage body 2 for exhaust gas sensible heat combustion while the combustion exhaust gas in the furnace 1 passes through a combustion gas heat storage body 3. During the combustion, the air for combustion is supplied to the air heat storage body 2 for combustion and preheated to be supplied to a burner 4 while a fuel gas is supplied to the fuel gas heat storage body 3. At the same time, water or steam is added to the fuel gas to improve gas reforming and a heating value by a reaction expressed by a formula of CmHn+mH2 O→mCo+n/2H2 .+ΔH (ΔH: endothermic reaction heating value) and supplied to the burner 4 for heating by combustion.  This enables preventing of the generation of soots within the burner 4 thereby upgrading the heat efficiency.

Title: Image communication device
Inventor: ONO TAKESHI
IPC: H04N1/34
Filed: 1986-10-07
Abstract: PURPOSE:To make a image communication with high picture quality without increasing the communication cost by selecting the mode of the highest picture quality forcibly among picture quality modes according to a stored reception-side telephone number at the time of picture quality determination. CONSTITUTION:A call signal is sent out based on a telephone number stored in a RAM 10 and a digital discrimination signal from a reception side is re ceived. Then, it is decided whether or not the telephone number of the receiving office in communication which is stored in the RAM 10 is a local number. Consequently, when so, information indicating that the transmission is performed in fine mode is contained in an information field and a DSC signal is sent. Consequently even if the communication time increases, the fine mode is speci fied all the time in a local area where the additional charge is small, and a normal mode or the fine mode is specified by an operator in other areas. Thus, an image communication with high picture quality in fine mode is made as much as possible without increasing the communication cost.

Title: High frequency gain temperature compensating circuit
Inventor: FUKUDEN NOBUTOSHI
IPC: H03H7/25
Filed: 1983-12-14
Abstract: PURPOSE:To increase the width of a gain compensating value due to temperature change to a large value by impressing a voltage to a high frequency variable resistor from a temperature compensating power circuit having a thermister and plural resistors via a diode. CONSTITUTION:A voltage is impressed to the high frequency variable attenuator ATT provided with a PIN diode from the temperature compensation power supply circuit comprising the thermister Th, the resistors R5, R1d and a constant voltage source S0 via a diode D0. When temperature rises, the resistance value of the resistance of the thermister Th is decreased, the voltage impressed to the attenuator ATT is decreased and the current flowing to the attenuator ATT is decreased thereby reducing the attenuation. Thus, the attenuator ATT shows the inverse characteristic as that of a transistor and the temperature compensation is attained through this operation. The change of rate of the current flowing to the ATT is increased against the temperature change by inserting the diode D0 in this case, allowing to attain the temperature compensation with increased sensitivity.

Title: Optical signal transmission system
Inventor: SUZUKI TAKAMASA
IPC: H04J14/02
Filed: 1986-10-08
Abstract: PURPOSE:To increase the transmission speed while securing the S/N by dividing transmission data into plural data and modulating respective data different frequencies to transmit them and processing received divided data in time series in a light receiving side. CONSTITUTION:Transmission data 10 is divided into N-number of data by a data divider 14 and is sent to modulators 11-13. These divided data are simultaneously transmitted to a data receiving part 2 through LEDs LED0-LEDn. Received signals are amplified by light receiving amplifiers 21-23 having resonance frequencies f0-fn in the data receiving part, and in this case, carrier waves are eliminated to take out signals in divided base band levels. They are restored to an original signal by a data restoring device. Thus, the data transmission speed which is intrinsically reduced by the influence of the band width of a resonance circuit is kept high by data division while keeping the high S/N.
