Title: Method of avoiding coating in partial combustion furnace
Inventor: KUMAGAI CHIKANORI
IPC: F23G5/30
Filed: 1997-02-10
Abstract: PROBLEM TO BE SOLVED: To enable continuous stable operation of a partial combustion furnace by a method wherein a free board part of the partial combustion furnace is cooled and furthermore, the amount of primary air and the amount of combustibles supplied are so controlled that the temperature of the free board part keeps a range enough to cause no coating trouble by inorganic chloride or tar components in ashes. SOLUTION: A cooling medium (water or air) passed through a heat exchanger tube 34 is detected by a flow rate indicator 36, the temperature of a free board part 32 by a thermometer 38 and values thereof are inputted into an arithmetic device 40 to control motors 42, 46 and 50 so that the temperature of the free board part 32 keeps a range of 400-770 deg. preferably 450-700 deg.C in which the temperature does not exceed the melting point of inorganic chloride while allowing avoiding of a coating trouble otherwise caused by a tar component. The preheated air to be supplied to a fluidized bed combustion furnace 18 is adjusted by a valve 49 (fore example, damper). This enables avoiding of a coating trouble otherwise caused by the inorganic chloride and tar components in a partial incinerator 10 thereby enabling continuous safe operation.

Title: Solid-state image pickup
Inventor: MURAKAMI SHINICHI
IPC: H04N5/335
Filed: 1993-03-03
Abstract: PURPOSE:To prevent a white deficiency caused by a long period non-use state of an image pickup device and to protect a solid-state image pickup element by continuing the impressed voltage to a solid-state image pickup element also when the image pickup device is unused. CONSTITUTION:The polarity of a diode 40 is selected so that forward direction current may flow toward a connection line 41 when substrate voltage is plus. This diode 40 is composed of the one having a reverse bias wirhstand voltage which is more than substrate impressed voltage at the time of driving a shutter. A back-up power source 5 is composed of a battery which is around substrate impressed voltage. At the time of using this image pickup device, reverse bias voltage is impressed on the diode 40 and the voltage of the power source 5 is not impressed on a substrate terminal 4. At the time of the non-use of the image pickup device, a power source switch 9 is turned off and output voltage from a circuit 8 to an output line 41 disappears. Therefore, the voltage of the power source 5 is impressed from the diode 40 to the terminal 4.
