Title: Gasification of coal and its device
Inventor: KOYAMA SHIYUNTAROU
IPC: C10J3/54
Filed: 1981-03-06
Abstract: PURPOSE: To improve the gasification efficiency, by introducing fine particles scattered from a gasification furnace of fluidized bed to a high-temperature gasification furnace, burning it partially to give formed gases such as H 2 , CO, etc., feeding them to the gasification furnace of fluidized bed.  
     CONSTITUTION: The granulated coal 1 is fed to the gasification furnace 13 of fluidized bed, and decomposed thermally to form char, tar, gas, etc. While, a gasifying agent comprising the steam 4 and oxygen is fed from the bottom of the gasification furnace 13 to it, the formed char is partially burned to give the gas 3 consisting essentially of CO 2 , CO, H 2  and H 2 O. This formed gas 3 is exhausted from the top of the gasification furnace 13, introduced to the cyclone 14, the fine particle char 15 scattered together with the gas 3 is recovered, and it is fed to the high-temperature gasification furnace 12. The steam 4 and the oxygen or air 5 are fed to it, and the char is gasified at a temperature ≥ the melting point of the char 15. The formed gas 6 is fed to the feed position for coal of the gasification furnace 13, and ashes are recovered as the slag 8.

Title: Local heating/cooling device
Inventor: HONDA SHOHEI
IPC: F24F3/06
Filed: 1998-02-13
Abstract: PROBLEM TO BE SOLVED: To heat or cool a room that requires heating/cooling by a local, simple means. SOLUTION: A steam pipe 5 that is laid through a room 1 is wrapped by a simple duct 9. A short pipe for mounting a plurality of discharge ports 8 and a bellows duct 10 is provided in the simple duct 9. A fan 11 is mounted to the tip part (terminal part) of the bellows duct 9. When the fan 11 is started, air being heated in the simple duct 9 exits the discharge port 8 for heating the room 1, thus dispensing with providing an exclusive air-conditioning duct and supplying heating as needed. Also, by forming the steam pipe 5 and the simple duct 9 in one piece, the space of the room 1 expands and the space can be utilized. By using a cooling pipe instead of the steam pipe 5, cooling operation can be made.

Title: Rolling method for thick plate
Inventor: SATOU TAKASHI
IPC: B21B1/06
Filed: 1981-03-06
Abstract: PURPOSE:To relieve a shock due to biting as compared with that of a conventional rolling method and to reduce the excess thickness at the top and bottom parts of a plate, by keeping the roll gap narrower than that of other part and rolling said plate while a part of a rolling material which is failed in biting passes through rolls. CONSTITUTION:A thick plate is rolled by the following procedure while controlling the temp. of a rolling material by cooling it forcibly on the way of rolling. In this case, the side shapes of a steel plate 1 at the exits of the ith pass and the (i+1)th pass between the initial temp. controlling pass and 2-3 passes before the final pass in said rolling step are shown in the figure. That is, reverse rolling is generally used for a thick plate, and then the part which is failed in biting at the ith pass becomes the bitting part at the (i+1)th pass. In this invention, the thickness of the part 2 which is failed in biting is made thin by setting the roll gap at the time when the part 2 of the plate 1 at the ith pass passes through the roll 3, narrower than that of the part through which other parts have passed already.

Abstract: PURPOSE:To prevent the generation of foaming trouble though the integral molding of a shape holding plate and a foamed resin is employed by coating an upper mold with a reaction curable resin and subsequently injecting a foamable resin raw soln. into a lower mold to perform reaction curing. CONSTITUTION:The inner surface 4 of an upper mold is coated with a reaction curable resin raw soln. 7 and the cured resin layer conforming to the shape of the inner surface 4 of the upper mold is bonded to the inner surface 4 of the upper mold at the coated part to become a shape holding plate 8. Thereafter, a foamable resin raw soln. 10 is injected into a mold cavity to form the integrally molded product consisting of the shape holding plate 8 (cured resin layer) bonded and formed on the upper mold 2 and a foamed resin. Since the shape holding plate 8 (cured resin layer) is bonded to the inner surface of the upper mold, even when the upper mold 2 is clamped immediately after the foamable resin raw soln. 10 is injected in the cavity 3 of the lower mold, the raw soln. 10 does not enter the gap between the shape holding plate 8 and the upper mold 2 and the shape holding plate 8 is not compressed and deformed.
