Title: Treatment of exhaust gas
Inventor: TAMAURA YUTAKA
IPC: B01D53/94
Filed: 1990-03-15
Abstract: PURPOSE:To more reduce a harmful component by performing the catalytic reaction of exhaust gas containing at least oxygen and carbon monoxide with magnetite at predetermined temp. CONSTITUTION:When exhaust gas containing oxgen and carbon monoxide is supplied to a reaction chamber 1, magnetite is changed to gamma-Fe2O3 by the contact with the exhaust gas and oxygen can be removed. When carbon monoxide comes into contact with gamma-Fe2O3, gamma-Fe2O3 is changed to Fe3O4 and carbon monoxide can be removed. By this method, harmful carbon monoxide can be almost perfectly removed to largely contribute to the promotion of the health of a human body and the improvement of the environment of the earth. Oxygen can be also removed and nitrogen oxide in the exhaust gas said to be especially difficult to treat from a diesel engine can be easily decomposed, for example, by the use of a catalyst.

Filed: 1979-05-29
Abstract: PURPOSE:To realize the high-speed printing without causing any discontinuous point, by selecting the blocks sequentially and one by one along one way within each group and then securing the opposite direction to each other between the adjacent groups. CONSTITUTION:Picture signal A equivalent to one line and supplied from the picture signal producing circuit is divided into two groups. Then the signals of first-half 15 bits and the signals of second-half 15 bits are written into RAMI and II like B1 and B2 respectively. And during writing into RAMs, the signals on the preceding line are delivered by three bits to shift registers III and IV like C1 and C2 each. Accordingly, three bits up to the 1st-3rd bits plus 30th-28th bits are supplied to registers III and IV each in the first printing. And in the first printing, the electrode is selected so that the fixed signal may be supplied for the specified period to common electrodes 121-1210 of the heat-sensitive head 10. Thus the heat generation is secured for the element which gives the black signal among the heat generating elements. In such way, no pitch difference is caused by the paper feeding and at the boundary between the two groups, thus ensuring the pringing with no discontinuous point caused.

One side of the membrane is contacted to an alkali soln. such as NaOH soln. at 5W100°C to induce hydrolysis, and dipped in an acidic soln. such as hydrochloric acid to prevent hydrolysis of the acid halide from proceeding. The other side is dipped in a soln. of a prim. or sec. amino cpd. such as polythyleneimine to convert the acid halide groups into acid amide groups, forming amide bonds. Next by contact to an alkali soln. again the residual acid halide groups in the membrane are hydrolyzed to produce a desired cation exchange membrane.

Title: Color copy system
Inventor: KATO ATSUNORI
IPC: H04N9/79
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To copy a color original in a short time. SOLUTION: In this system, first a scanner 22 of a multi function circumferential unit MFC 1 reads a picture of a color original to obtain RGB analog data, an ASIC 18 converts the data into CMYK digital binary data, which are sent to a PC 50 (41). Since the CMYK binary data are image data of a form printed by a printer 25, it is not required for the PC 50 to convert the form of the CMYK data. Then a color copy application 57a of the PC 50 receives the CMYK binary data of all the original and transmits the data sequentially to the MFC 1 in the case of printing the data by the printer 25 of the MFC 1 (42). Thus, a color copy system 80 applies copy processing to the color original in a short time with high accuracy.

Abstract: PURPOSE:To reduce the sliding speed of an eccentric shaft in relation to a rotor by an intermediate rotor so as to suppress the sliding speed and wear compared to the case of the eccentric shaft sliding in direct contact with the rotor by fitting the eccentric shaft with play, and additionally providing the intermediate rotor fitted with play inside the rotor. CONSTITUTION:An oil pump is formed by disposing an intermediate rotor 121 between an eccentric shaft 101 and a rotor 104, and the outer peripheral surface of the rotor 104 is brought close to the inner peripheral surface of a cylinder 102 to partition a crescent moon shape cylinder chamber 105. When the eccentric shaft 101 is eccentrically rotated at the specified angular velocity OMEGA1, the intermediate rotor 121 is pressed toward the rotor 104 while being autorotated at the relatively low acceleration OMEGA2 following the eccentric rotation of the eccentric shaft 101. At the same time, the outer peripheral surface of the rotor 104 is pressed by the intermediate rotor 121 so as to perform revolving-turning motion while coming close to the inner peripheral surface of the cylinder 102. Lubricating oil is therefore sucked into an oil inlet chamber 109 from an oil inlet passage 112 and discharged to an oil feed hole 52 from an oil discharge chamber 110 through a discharge passage 113.
