Title: Operation of blast furnace
Inventor: UNO SHIGENORI
IPC: C21B5/00
Filed: 1980-02-14
Abstract: PURPOSE:To prevent blowing-through and to maintain a safety operation in low burden level or low burden-level blowing-down operation by adjusting air-blowing amount and furnace-top pressure at the time when the distance between the top layer of the melt-deposit zone and raw material burden level varies abnormally. CONSTITUTION:In the process of lowering the burden or raising the burden level, the shape of the melt-deposit zone is esitimated continuously, and when the top layer of the melt-deposit zone approaches the burden and results in a decreased amount of block-type burden just above the melt-deposit zone, an operation is performed to reduce the amount of blowing or to increase the furnace top pressure. In this process of operation, when the above distance becomes abnormally small, the furnace-top pressure is raised in advance, gas flow is suppressed, thereafter the amount of blow is decreased; in this manner, the above distance can be maintained at the specified value, and blowing-through and a large slip can be prevented. The decreased amount of air blow is properly at about 0.1Nm<3> per inside capacity; however, if there is a delay in lowering the top pressure, then, the decreased amount of air blow is preferably at about 0.15-0.20Nm<3>/min per inside capacity.

IPC: H01L21/56
Filed: 1999-01-26
Abstract: PROBLEM TO BE SOLVED: To avoid leaving unfilled parts and eliminate the bulk reducing trend of a resin filled layer by pushing and filling a part of a seal resin of an excessive supply layer into stencil holes, utilizing the air pressure difference. SOLUTION: A squeegee 5 is adjusted to locate above the top face of a stencil plate 3 with a space 7 required for excessively supplying between the stencil plate 3 top face and the squeegee 5. The squeegee 5 operation forms a resin excessive supply layer 8, including pass holes 6 on the stencil plate 3. After the push-filling of a seal resin 4 by the squeegee 5 operation. After the push-filling of the seal resin 4 in a vacuum atmosphere, the vacuum degree in the atmosphere is lowered to or near to the atmospheric pressure, thereby causing a pressure difference between unfilled parts and outside atmosphere. This pressure difference causes the seal resin 4 to be pushed into the unfilled parts, thus removing the unfilled parts, while the excessive resin layer 8 reduces its bulk to form recesses at regions above the pass holes 6.

Title: Fuel cell power generation device
Inventor: IKEDA GENICHI
IPC: H01M8/04
Filed: 1995-02-03
Abstract: PURPOSE: To reduce the quantity of the combustion air flowing back to a fuel cell by opening a valve of a discharge pipe branching off from an offgas supply system at starting-temperature rising time of the reforming pipe of a fuel reformer. CONSTITUTION: When a fuel reformer 3 is started, a reforming pipe 9 is raised up to a temperature suitable for reforming steam by heating of a heat medium generated by burning raw material fuel for starting by a burner 7 by combustion air supplied after a temperature is raised by a blower 14. Since a combustion air supply system 15 and an offgas supply system 17 are communicated with each other by the burner 7, the combustion air supplied to the burner 7 has the possibility of flowing backward to the offgas supply system 17 from the burner 7. At this time, a valve 40 of a discharge pipe 41 branching off from the offgas supply system 17 is opened, and the most part of the combustion air flowing backward in the offgas supply system 17 is discharged to the atmosphere through the discharge pipe 41. Therefore, a combustion air quantity reversely flowing to a fuel cell 2 is reduced.  Therefore, open circuit voltage to start power generation of the fuel cell at the starting time of a fuel power generation device 1 is obtained by specified voltage, and an excellent condition can be kept.
