Title: Process and apparatus for reducing material to be heated by heating in reducing atmosphere
Inventor: FUJII KINJIROU
IPC: B01J19/00
Filed: 1984-03-07
Abstract: PURPOSE:To obtain a simple and widely applicable heat-reducing process in a reducing atmosphere by shielding a material to be heated with a curtain of a laminary flowing reducing gas in a furnace and transmitting heat generated at the outside of the curtain to the material to be heated through the curtain. CONSTITUTION:The reducing gas supplied from a nozzle 11 is ejected in the form of horizontal flow like a curtain from a slit 3 through a gas storage 2. The gas flows above a pit 1 contg. the material to be heated, enters a space before a counter wall 6, and passes through the space toward above. On one hand, oxygen or a previously prepd. combustion gaseous mixture comprising O2 and fuel gas is supplied from a burner port 4 to burn the reducing gas in the furnace 5, and the material to be heated in the pit 1 is heated by the generated radiant heat. By this apparatus, smelting of metal, production of nonoxide raw material, or heat-reduction of a material in a reducing atmosphere suited to heat treatment of a metal is achieved without resulting generation of a large amt. of slug or CO, nor consumption of a large amt. of electric energy.

Title: Air intake device for multicylinder engine
Inventor: SHIRAISHI HIDEO
IPC: F02B75/22
Filed: 1985-03-05
Abstract: PURPOSE:To reduce the fluctuation of air-fuel ratio in deceleration of an engine by making the air intake passes of cylinders which are nonsequentially ignited communicate with volume chambers, the air intake pipes being classified in two groups, by closing an opening/closing valve for making the volume chambers communicate with one another in a higher speed range in deceleration of the engine, and by opening the opening/closing valve in a lower speed range in the deceleration. CONSTITUTION:Two groups of air intake passes 5a-5c and 5d-5f of cylinders which are nonsequentially ignited communicate with volume chambers 3 and 4. The volume chambers 3 and 4 communicate with each other through an opening/closing valve 12. An intake air quantity detector 17 is arranged in an air intake pipe provided in the pass upstream from the volume chambers. Fuel is injected from an injection valve 19 provided with each air intake port under the control of a controller 18. A difference is produced between the flow rate of intake air detected by the intake air quantity detector 17 and actual amount of intake air in the deceleration of an engine due to the effect of the volume chambers. Therefore,the opening/closing valve 12 is closed in a higher speed range in the deceleration of the engine and opened in such a lower speed range as including an idling speed, under the control of another controller 16 in response to an engine speed 14 and a throttle valve opening 15.

A piping temperature RH1 after a lapse of (t) time is detected and RH0 is compared with RH1. When the RH1 is not increased to a value higher than a specified value, it is decided that a solenoid valve 5 is failed in operation and there is a fear of drain leaking, and the compressor 2 is stopped. Even when one of indoor machines 7 and 12 is stopped due to the occurrence of drain abnormality, normal operation of an indoor machine in a room as safety of leakage of drain of an indoor machine under a stop is ensured.
