Title: Nitrogen reducing device
Inventor: TOMINAGA GENICHI
IPC: F02M33/00
Filed: 1984-07-19
Abstract: PURPOSE:To reduce an amount of nitrogen oxide contained in exhaust gas, by a method wherein an amount of nitrogen contained combustion air is reduced to feed the combustion air to a combustion chamber. CONSTITUTION:Air is fed through an inlet 1 of a spiral pipe, the air is rotated within the pipe, and through utilization of a difference in specific gravity between oxygen and nitrogen, oxygen being low in specific gravity and nitrogen being high in specific gravity are taken out through a take-out port 3, formed in the internal side of the spiral pipe, and an exhaust port 2, respectively. Air increased in an oxygen component, which is taken out through the take-out port 3, is fed to a carburetter to burn it in a combustion chamber. This enables reduction of an amount of nitrogen oxide contained in exhaust gas.

Filed: 1984-07-18
Abstract: PURPOSE:To perform safe and economical replacement, in withdrawing the catalyst used in the reaction of hydrocarbons in a chemical plant, by primarily wetting the catalyst with mineral oil at first before secondarily wetting the same with paraffin or heavy oil. CONSTITUTION:Prior to entering the stopping of operation, the temp. of a heating furnace 4 is lowered to gradually lower the temp. of a reactor 7. Next, the opening and closing valve 2 of supply piping 1 is closed while the opening and closing valve 25 of primary coating solution supply piping 26 is opened and a coating solution is replaced with mineral oil such as light oil to perform cycle temp. of the reactor 7 is further lowered while the reactor 7 is substituted with inert gas to lower the pressure in the system and the tower top of the reactor 7 is opened and a pump 28 is driven to scatter the secondary coating solution such as paraffin or heavy oil in a tank 29. By this method, a catalyst is replaced and the generation of heat is prevented and the oxidation of the catalyst is also prevented.

Title: Pneumatic cylinder equipped with shock absorber
Inventor: TAKAHASHI TAKAMICHI
IPC: F15B15/22
Filed: 1979-11-19
Abstract: PURPOSE: To reduce the length of the entire structure of a pneumatic cylinder and to obtain a high trust, by fitting a pneumatic piston having a pneumatic piston rod in the body of a pneumatic cylinder in freely slidable manner, and forming an inner chamber in the piston rod.  
     CONSTITUTION: When a load is acted to the outer end of a pneumatic piston rod 3, hydraulic oil in a pressure chamber 4 2  flows into an accumulator chamber 4 1  through an orifice 10 formed in a fixed partition wall 5 along with retracting movement of rod 3, so that the volume of a fixed rod 6 immersed in oil is increased. Resultantly, a free piston is slided toward head cover 7, so that the load can be absorbed. On the other hand, for imparting a thrust to the absorbed load, compressed air is supplied into a pneumatic cylinder 1 through an air inlet and outlet  port 14 for causing sliding movement of pneumatic piston 2 toward the rod, where by a high thrust can be obtained since the pneumatic pressure receiving area of  piston 2 is larger than the hydraulic pressure receiving area of a partition wall 5.

Title: Picture processor
Inventor: TSUTSUMI YASUHIRO
IPC: G06T5/00
Filed: 1993-06-21
Abstract: PURPOSE:To obtain a picture processor by deciding a binarization processing error based on an input picture element density and a predetermined threshold level and using the binarizing processing error, and thereby correcting the picture element density in the vicinity of a picture element thereby realizing the picture element average density expected for the threshold level for binarization processing. CONSTITUTION:A binarization processing section 70 is provided with an error decision means 72 and a correction means 74, a multi-gradation picture digital signal given from a control section 58 is binarized into a white level signal and a black level signal by using an error propagation method based on the predetermined threshold level to output the binarized signal. In this case, the error decision means 72 decides a binarized processing error based on the input picture element density and the threshold level. Moreover, the means 72 decides an error so that a total error in a dither matrix is almost zero. Then the picture element density in the vicinity of the picture element is corrected by using the binarization processing error decided by the correction means 74. Since the binarization processing error is corrected based on the threshold level in this way, an output picture element ratio of a desired halftone gradation is obtained.

Abstract: PURPOSE:To automate ignition, as well as to keep safety, by adding a function of automatic igniting operation which repeats ignition tries as many times as is preset by a counter circuit at the time when igniting operation is failed, to a combustion controlling device. CONSTITUTION:When an igniting operation is failed, a timer up signal is fed into the terminal 2 of an one shot multivibrator circuit 9 from a safety timr circuit 6 at the moment when a timer in the circuit 6 is up and the voltage in it is changed into H- level. Then the H-level signals from the output terminal 3 of the circuit 9 are fed into a reset circuit 10 to actuate it, for a specified time being set by a constant value at the time of C9 and R9. The reset circuit 10 resets both prepurge timer circuit 5 and safety timer circuit 6, and at the same time, it feeds a rise signal generated at the moment when the voltage in the circuit 10 is changed from L to H into the clock input terminal 14 of a counter circuit 11. The voltage in the circuit 11 is changed by the rise signal fed from the reset circuit 10. An igniting operation is tried again, after the prepurge timer circuit 5 is reset to the initial state by the reset circuit 10. When the count set in the counter circuit 11 is up, SCR in a safety switch circuit 4 is actuated, and an abnormal state is alarmed by an alarm buzzer B, as well as to stop the igniting operation by a diode D4 in the safety switch circuit 4.

Abstract: PURPOSE: To prevent damaging of bundled material and improve yield by slidingly abutting the sliding part of a rotary blade supporting part on the strap on the surface of the bundled material and advancing the rotary blade supporting part thereby giving a score in the thickness direction of the strap and force-cutting the same.  
     CONSTITUTION: A strap cutting head 4 is press-fixed with the surface of a coil 1 by means of a cylinder 6, and a rotary blade supporting member 11 of an inverted U shape in section carrying a sliding member 10 and a rotary blade 20 is advanced by means of an air motor.

At this time, the rear projecting part 19 of the member 10 operates a limit switch 30 which in turn rotates the rotary blade 20 by means of the air motor, whereby a score is given in the strap 2. When it crosses the entire width of the strap 2, it operates a limit switch 31 which in turn stops the rotary blade 20. Thence, the strap 2 is pressed by the pawl 17 and is thereby forcibly separated. The sliding member 10 is reset by the replusive force of the elastic body 15.
