Title: Spray type combustion equipment
Inventor: DOI ATSUSHI
IPC: F23M5/08
Filed: 2000-06-14
Abstract: PROBLEM TO BE SOLVED: To obtain spray type combustion equipment which can prevent the occurrence of failures caused by heat by preventing the transfer of heat to the preceding stage side of its main body section. SOLUTION: This spray type combustion equipment has the main body section 2 which is divided in to the preceding state side 5 and a heat exchanger side 6 and incorporates the main body 3 of a heat chamber. The boundary between the preceding stage side 5 and heat exchanger side 6 of the main body section 2 is defined by a partition wall 12. A demarcation wall 43 is provided practically in parallel with the partition wall 12 near the wall 12 on the preceding stage side 5 of the main body section 2. The air flow on the preceding stage side 5 is supplied to the heat exchanger side 6 through the gap between the walls 43 and 12. Therefore, an air layer which functions as a heat insulating layer is formed near the partition wall 12 and, accordingly, the heat on the heat exchanger side 6 is not transferred to the preceding stage side 5.

Title: Variable gain amplifying system
Inventor: NAKAMURA KATSUSHI
IPC: H04N5/20
Filed: 2000-06-15
Abstract: PROBLEM TO BE SOLVED: To eliminate offsets of a charge coupled device(CCD) and a correlation double sampling circuit(CDS) at a simplified circuit and by a low power consumption by equipping a first offset correction circuit on an upstream side of a programmable gain amplifier and a second offset correction circuit on a downstream side of the programmable gain amplifier. SOLUTION: In this system, two offset correction loops are applied. That is, one is applied to an input 500 of a PGA 104 and the other to an output 502 of the PGA 104. With the correction of an input offset, an offset of a CCD and the offset of a CDS 102 are eliminated. Output offset correction next eliminates an input offset of the PGA 104 and uncorrected offset from a first offset correction which is called an output of the PGA 104. Since almost all offset contributions are eliminated before the PGA 104, offsets which an output loop has to correct are reduced greatly.
