Title: Electronic equipment having heat dissipation mechanism
Inventor: IIIZUMI TAMIO
IPC: H05K7/20
Filed: 1992-06-09
Abstract: PURPOSE:To contrive a collective cooling of a plurality of circuit boards even if the interval between the boards is narrow by a method wherein a heat transfer member is made to engage with heating units mounted on the circuit boards and a heat dissipation member is brought into contact with the heat transfer member. CONSTITUTION:When a circuit board rack 12 is stored, an operating rod 7 is pressed by a one surface slant projection 8. The rod 7 is slided to the side of a heat dissipation member 5 and presses the end part of a pressing lever 6. The lever 6 presses the member 5 to the side of the rack 12 by its other end with a support pin 10 as a support. The member 5 is pressed by a heat transfer member 4 and comes into contact with the member 4. When heat is generated by heating units 2, the heat is conducted to the member 5 through the member 4 and is dissipated. When the rack 12 is drawn out, the member 5 is moved to the opposite side to the rack 12 and is separated from the member 4. Thereby, a plurality of circuit boards can be cooled en bloc.

Title: Nozzle for fuel gas generator
Inventor: SUZUKI SHIGERU
IPC: F02K9/97
Filed: 1985-07-09
Abstract: PURPOSE:To aim at preventing glanular materials such as metal fuel from sticking and accumulating to a nozzle for a rocket charged with a natural solid gas generating agent containing metal fuel, by forming a dried water glass film on the inner surface of a nozzle body of a fuel gas generator. CONSTITUTION:A graphite nozzle body 21 is formed therein with a throat part 21a, a convergent part 21b and a divergent part 21c the surfaces of which are coated thereon with a dried water glass film 22 having a maximum thickness in the vicinity of the throat part 21a. Accordingly, when a heat is transmitted from the stream of fuel gas to the dried water glass film 22, water retained in crystals in the film 22 is deposited to gradually come out the film 22 and develops on the outer surface of the film 22, and the water is evaporated to protect the film 22 against heat due to the latent heat of evaporation while a boundary layer is formed between itself and the fuel gas stream. Thus, it is possible to obtain a smoothness of the inner surface of the nozzle 20 and to prevent granular materials such as, for example, metal fuel from sticking to the inner surface so that it is possible to satisfactorily sustain the combustion pressure and the amount of fuel gas.

Title: Operating method for blast furnace
Inventor: OKUMURA KAZUO
IPC: C21B5/00
Filed: 1981-09-22
Abstract: PURPOSE:To prevent the decrease in reduction efficiency of gases by charging raw materials contg. high moisture in the zone of the inside of the furnace where the effect that the moisture in the raw materials gives upon the reduction efficiency of gases is small. CONSTITUTION:If there is a need for charging raw materials of high moisture in blast furnace operation, said materials are charged in the zone where the effect that the moisture of the raw materials gives upon the reduction efficiency of gases is small, that is, the zone where the temp. of the gases is about >=100 deg.C, in accordance with the measured results of the temp. distributions in the radial direction of the blast furnace.

Abstract: PURPOSE: To facilitate the reproduction of the lever location by a mechanism wherein a notch is formed at a section which is inserted into a lever hole of a supporting pin and two edges are made up.  
     CONSTITUTION: A notch 45 is built up at a section inserted into a lever hole of a supporting pin 43 and two edges 47, 49 are formed, and a hole 38 of a lever 37 and the supporting pin 43 are contacted at two points arranged in the direction approximately crossing at right angles in the direction of push force F applied to the supporting pin 43 from the lever 37.
