Title: Catalyst for removing nitrogen oxide in exhaust gas and production thereof
Inventor: KATO YASUYOSHI
IPC: B01J23/30
Filed: 1993-12-13
Abstract: PURPOSE:To provide a catalyst for removing nitrogen oxide enhanced in initial activity and reduced in the lowering of activity even when used for a long period of time. CONSTITUTION:A catalyst for removing nitrogen oxide catalystically reducing and removing nitrogen oxide in exhaust gas using NH3 is obtained by preliminarily making a vanadium compd. and a molybdenum compd. and/or a tungsten compd. adsorbed and supported on rutile type titanium oxide and subsequently mixing anatase type titanium oxide in a wt. ration of 99/1-50/50 to interpose the same between rutile type titanium oxide particles. Therefore, the catalyst excellent in initial activity is obtained and, since the lowering of activity caused by the conversion of titanium oxide being a catalyst carrier into rutile type titanium oxide with the elapse of use time is prevented, heat resistance is high and high activity can be kept for a long time.

IPC: H02N2/00
Filed: 1994-12-16
Abstract: PURPOSE: To absorb the vibration of the surfaces of mobile rails so as to easily control and smoothly move the rails by elastically holding a vibrator between means which forcibly push the rails while they are faced to each other in the direction perpendicular to the moving direction of the rails. CONSTITUTION: The transmitting members 22 of a vibrator 20 are brought into contact with the contacting surfaces 12b of a pair of mobile rails 12 and put in ball bearings 11 in the V-shaped grooves 12a of the rails 12. When the members 22 are put in the bearings 11, a C-direction moving habit is given to a right-side guide member 7 and a D-direction moving habit is given to a left-side guide member 7 by springs 10 and moving habits are given to the rails 12 in opposite directions. Therefore, the vibrator 20 is horizontally held between the rails 12. Therefore, even when the mirror-finished contacting surfaces 12b of the rails 12 vibrate, the vibration can be absorbed, because the vibrator 20 finely vibrates together with the rails 12 in the horizontal direction.

Filed: 1991-10-31
Abstract: PURPOSE:To bring about the same effect as erasing of data on a recording track by updating discrimination data, which discriminates recorded data on the recording track, to prescribed erase discrimination data and stopping the reproducing operation based on this data. CONSTITUTION:A data recorder controller 12 is used to assign track classification information, where '1' is continuous, to erase discrimination data, and the reproducing operation is stopped if this data is recorded. Thus, the output of recorded data is stopped by only updating the track classification information to erase discrimination data in the controller 12, and the same effect as erasing of data on the pertinent recording track is obtained. Consequently, desired data is easily erased without providing an erase head.

Abstract: PURPOSE:To improve joint strength, corrosion resistance, brazability. rebrazability, etc., by using titanium and titanium alloy as a core material, cladding silver directly to the surface thereof and cladding a silver alloy to the surface thereof. CONSTITUTION:The titanium and the titanium alloy are used as the core material 1 and a cylindrical material 2 is clad to the surface thereof. Further, a silver alloy cylindrical material 3 is directly clad to the surface thereof. The titanium which is the core material 1 is light and has the excellent corrosion resistance and an adequate strength and is extremely outstanding as the spectacle material. The silver alloy cylindrical material 3 which is one of noble metals is used as the surface layer in order to take advantage of the characteristics possessed by the titanium and to enhance a design characteristic. The silver cylindrical material 2 is used as an intermediate layer between the core material 1 and the surface layer. The silver cylindrical material 2 is used between the core material 1 and the surface layer as a intermediate layer. The copper and titanium in the silver alloy used for the surface layer react preferentially to form a brittle intermetallic compd. and, therefore, such reaction is required to be prevented. On the other hand, the direct joining of the silver and the titanium is possible and, therefore, the silver is used as a barrier material.
