Title: Exhaust gas cooling device for crematory furnace
Inventor: NAGAO MOTOJI
IPC: F23G5/46
Filed: 1999-05-18
Abstract: PROBLEM TO BE SOLVED: To reduce temperature of a high temperature exhaust gas in a short time by introducing the high temperature exhaust gas to each of regenerative exhaust cooling chambers by conducting switching at a given time interval, blowing cool air to regenerative body beds of a first and a second regenerative exhaust gas cooling chamber, respectively, and discharging temperature raised air that comes from the regenerative body beds of the regenerative exhaust gas cooling chambers. SOLUTION: High temperature exhaust gas from combustion furnaces 1, 2 is alternately passed through regenerative exhaust gas cooling chambers 5a, 5b by conducting switching at a given time interval to drastically conduct cooling. Specifically, when the high temperature exhaust gas is passed to the chamber 5a through a passage 3a, a channel switch damper 4a, an exhaust switch valve 8a, a heated air valve 7b and a blow switch valve 10b are fully opened, and a channel switch damper 4b, an exhaust switch valve 8b, a heated air valve 7a and a blow switch valve 10a are completely closed. When the high temperature exhaust gas is passed to the chamber 5b, the above opening and closing actions are conducted the other way round. Thus by switching each of the dampers and switch valves at a given time interval, temperature of the combustion exhaust gas can be reduced in a short time.

Title: Article take-out port of automatic device machine
Inventor: SATO TADASHI
IPC: G07F9/00
Filed: 1988-06-03
Abstract: PURPOSE:To cushion or reduce the impact of an article to a receiving box and burglarproof plate by forming the receiving box and a burglarproof plate of a sandwich steel plate. CONSTITUTION:An article 13 carried out of a column 5 slides down a chute 8 and hits a burglarproof plate 20 after opening a small door 7. Then the article 13 drops to a receiving box 19. When the article 13 hits the plate 20, the plate is swung forward by the impact of the article 13 and the edge of the plate 20 hits the inner surface of a door 9 around a take-out port 19. Since the receiving box 19 and burglarproof plate 20 are formed of a sandwich steel plate holding a resin layer between steel sheets, the impact energy and sounds of the article 13 are absorbed by the resin layer acting as a cushion. Thus the impact and impact sound of the article can be reduced.

Title: Tig welding flux of stainless steel
Inventor: KANAYAMA KIYOSHI
IPC: B23K35/36
Filed: 1999-05-19
Abstract: PROBLEM TO BE SOLVED: To enable deep penetration welding without generating a fluorine gas by containing SiO2, CrO and specifying the range of the content ratio of Cr2O3/SiO2. SOLUTION: This flux in which a content ratio value of Cr2O3/SiO2 is in a range of 0.15-2.0. When using the flux in which a content ratio of Cr2O3/SiO2 is mixed to a range of 0.15-2.0, the surface tension of a molten pool is turned to <=600 dyne/cm, the surface tension is greatly reduced as compared to the case except this range. Furthermore in the range of a content ratio of 0.15-2.0, regardless of the increase in the input heat quantity, the surface tension is maintained in a prescribed range. The flux, in TIG welding of a stainless steel, increases the penetration depth to improve welding part quality and to shorten a welding time. The flux does not generate a fluorine gas, a simple clothing is acceptable for working, and set up time is shortened as well.

Title: Device for guiding sheet
Inventor: SUTEIIBU ESU KUNOOPASU
IPC: B65H5/36
Filed: 1993-06-10
Abstract: PURPOSE: To prevent the distortion of a toner image on a substrate, which is not fixed yet, by a method wherein a sheet guiding device is provided with a member, arranged so as to be adjacent to a transfer passage so that the member comes in contact with a sheet, moving to a process station, and a means for supporting the member movably to restrain the movement of the sheet into a direction crossing the passage. CONSTITUTION: A movable guiding device 100 is attached so as to be very much approximated to a nip, formed between a fixing roll 48 and a pressurizing roll 50. The movable guiding device 100 is constituted of a pair of elastic arms 104, supporting a rotatable star gear 102. The guiding device 100, having the star gear 102, is arranged close to the transfer passage for paper whereby the amount of flip in the rear edge is minimized. Thus, the chance of causing the distortion of the image of unfixed powder toner can be reduced. On the other hand, the elastic arms 104 deflect the star gear and absorb a force applied on the sheet due to the levitation of the rear end part of the sheet. Accordingly, the breakage of the sheet caused by the star gear or the like, can be prevented.
