Title: Reducing gas heating method and device therefor
Inventor: MORI TAKAAKI
IPC: C01B32/50
Filed: 1996-01-16
Abstract: PROBLEM TO BE SOLVED: To prevent the reduction in thickness caused by carbon deposition on the inner surface of a gas heating pipe and carburization-embrittlement of the heating pipe by rapidly heating at the temp. raising velocity having a prescribed value or higher in the dangerous temp. range easily depositing the carbon from a CO-containing reducing gas. SOLUTION: At the time of heating the reducing gas containing CO, the carbon is deposited by reaction 2CO←→CO2 +C. This deposited carbon is stuck onto the heating pipe and reacts with iron, and carburizing phenomenon is caused and the inner surface is embrittled and worn. This reaction is exothermic reaction, and according to the chemical equilibrium theory, the reaction is progressed to the right side as the temp. becomes lower, the carbon is easily deposited but on the other hand, since the reaction velocity is not high in the low temp., the dangerous temp. zone easily depositing the carbon exists. This range depends on the gas composition (particularly CO and CO2 concns.) and the operation pressure, but, this temp. is generally not over about 350 deg.C, at the time of heating this gas at >=1000 deg.C/sec temp. raising velocity, since the staying time of the gas is extremely short, such as <=0.35sec, the deposition of the carbon is effectively restrained.

Title: Input and output controller
Inventor: SUZUKI KUNIO
IPC: G06F13/38
Filed: 1985-01-18
Abstract: PURPOSE:To improve considerably the overall throughput of a system by changing automatically the data transfer speed at the device side according to the transfer address. CONSTITUTION:A CPU1, a memory GM4, a disk 7 and an I/O8 are connected with each other via a common bus 5 under the control of a bus controller 3. A selector 47 of the disk 7 selects either one of inputs D0-D7 by three output lines of a memory 45 and delivers it. In other words, an output 35 or 36 given from an MPU21 is delivered as it is in the form of a data transfer request to be given to the bus 5 if an input D0 is selected by the selector 47. However the output 35 or 36 is delivered with a delay if other inputs D1-D7 are selected. Therefore the data transfer interval to the bus 5 is varied by changing the value of the memory 45. Thus it is possible to change automatically the data transfer speed at the input/output device side according to the transfer address.

Filed: 1997-01-16
Abstract: PROBLEM TO BE SOLVED: To improve opening workability of a connecting mechanism by supporting pressing force acting on the connecting mechanism by insertion of an opening member by a pressure support means, and regulating displacement of the connecting mechanism. SOLUTION: A connecting mechanism 22 is internally installed in a stop ring 50, and an inserting port 31 and a recessed part 35 are made to conicide with a communicating port 51. When the connecting mechanism 22 (an element part 36) is opened, an opening member 25 is pressed in the recessed part 35 through the inserting port 31 from the communicating port 51 simultaneously when a plate-like pressure support member 52 is inserted from a window 53. Pressing force in the direction (the window 53 direction) for separating from the communicating port 51 which is imparted to the connecting mechanism 22 from the opening member 25, is supported by the pressure support member 52, and displacement of the connecting mechanism 22 is prevented.  Since deformation of the connecting mechanism 22 by press-in of the opening member 25 can be prevented, there is no fear of exerting adverse influence on aligning accuracy of an aligning mechanism in the connecting mechanism 22. Influence is not exerted on a light characteristic of optical fibers 33 and 34 held by a clamp in the connecting mechanism 22.

Title: Screw vacuum pump
Inventor: KAMETANI HIROCHIKA
IPC: F04C18/16
Filed: 1990-01-17
Abstract: PURPOSE:To maintain the temperature in operation nearly constant and make both high performance and reliability coexist by forming a water jacket in the interior of the part facing to the end face of a screw rotor in a casing end face part. CONSTITUTION:The bore part 3 of a casing is easily detachably jointed with the end face part 4, because the part 3 is not contacted with another member except the end face part 4. Hereby, when a screw rotor 1 is exposed to inspect and clean, it is enough to remove the bore part 3 of the casing. Further, a water jacket 9 is formed in the end face part 4 of the casing, but cooling ability is sufficient, because compression heat of gas is generated most in the vicinity of the discharge side end of the screw rotor 1. But when exhaust gas is much or cooling water temperature is high, there is the possibility that the cooling capacity is insufficient, hence the cooling capacity is increased by a means provided with a cooling water flow passage inside the screw rotor 1.
