Filed: 1987-06-09
Abstract: PURPOSE:To reduce the quantity of and the area of packing by executing two microprograms alternately for each microinstruction when it is required to perform simultaneously various processes for I/O instruction, the transfer of data, etc., via one microprocessor and one control storage. CONSTITUTION:A channel device 30 is controlled by a microprocessor 304 and one microprogram occupies the processor 304 to execute it when no simultaneous processing is required. Then two microprograms are execute alternately for each microinstruction when the simultaneous processing is required. Thus just the control storage 305 and the microprocessor 304 are reduced to one respecting and furthermore, two microprograms control the same hardware.

Abstract: PURPOSE:To easily manufacture gears and to measure the flow rate highly accurately by forming a pair of non-circular gears so that the gears are meshed in contact with each other in the regular gear profile only at a part of the face width and meshed out of contact from each other at the other face width. CONSTITUTION:First gears 8, 10 are of the same shape and same size. A gear part 8b having the length of the tooth trace L0 to be meshed regularly in contact with another gear, and a gear part 8a having the length of the tooth trace L2 to be meshed without contact are integrally formed to the face width L1. Second gears 7, 9 are contactless gear parts of the same shape and same face width L2. It is preferable that the tapering amount for realizing the noncontact gear parts 7, 9 is equal to that of the gear part 8a of the first gear. The first gear 8 and the second gear 7 are coupled to the same shaft to be one rachet gear. In the case where a pair of non-circular gears obtained by coupling the first and second gears are meshed, regularly meshed tooth trace parts 8b, 10b in contact with each other produce an accurate tooth profile.

IPC: B09B3/00
Filed: 1996-06-05
Abstract: PROBLEM TO BE SOLVED: To effect treatment of an exhaust gas without generation of plugging and take out heavy metals in an easily disposable configuration by causing an absorption liquid in a gas absorption tower to absorb dust and soluble components from the exhaust gas from an ash fusion furnace and burning CO gas in the exhaust gas from the gas absorption tower in a CO combustor. SOLUTION: Electric current is passed between an anode 1b on a furnace cover 1i and a cathode 1a on a furnace bottom in a direct current type ash fusion furnace 1 to melt ash 1j with electric resistance heat. The ash 1j molten is separated into an upper molten slug layer 1d and a lower molten metal layer 1c owing to a difference in their specific gravities, and an ash cover layer 1e with the non-molten ash 1j floating is generated above the molten slug layer 1d. Exhaust gas 2 is introduced into a gas absorption tower 3 and an absorption liquid is jetted from a nozzle 3c to absorb thereinto dust and soluble components. Then the exhaust gas 2 is conducted to a mist separator 4 from the gas absorption tower 3 for separation of water droplets, and CO gas in the exhaust gas is made to burn in a CO combustor 5.
