Abstract: PURPOSE:To regenerate catalytic activity by abrading a lamellate or honeycomb catalyst with granules harder than this catalyst and removing insoluble deposit from the surface of the catalyst. CONSTITUTION:A catalytic element 1 is slanted at a constant angle and granules 3 such as e.g. river sand and silica sand which are harder than a catalyst and are not more than 1mm are uniformly spread through a gas passage 2 of the catalytic element 1.

Inventor: SUZUKI NORIHIRO
IPC: H04N11/24
Filed: 1989-02-10
Abstract: PURPOSE:To compress a band on a pattern to 1/4 without reducing the quantity of information by dividing a TV signal into N at a frequency region, arranging N sets of the signals in the horizontal frequency direction and multiplexing them. CONSTITUTION:Field comb-line filters 1-4 are used for the processing at the sender side to divide the region into four regions. Then carriers f2-f4 of each component are modulated by a modulator 6 and the result passing through a delay element 5 having the same delay through BPFs 7-8 extracting each horizontal frequency is added by an adder 10. Then in the processing of the receiver side, an LPF 11 and the same BPFs 7-9 as those at the sender side extract each component and the signal is demodulated at a multiplier 6 by using the carriers f2-f4 at a multiplier 6. In this case, since a lower side band signal is a desired signal, each signal is given to the LPF 11 to obtain a substantial component. The signal is delayed at a delay element 12 and the result is added by the adder 10 to obtain the substantial signal.

Abstract: PURPOSE:To permit nonlinear action such as flip-flop action by coupling plural pieces of cells in a manner that the cells can cooperate with each other. CONSTITUTION:This element has plural pieces of unit elements each containing a nonlinear refractive index medium and means for inputting light to the medium. These elements are so coupled as to cooperate with each other in the relation that the output of one of plural pieces of the unit elements is coupled to the input of the other unit element. For example, the unit element is constituted of both of the nonlinear refractive index media 1-1-1-N and reflecting mirrors 2-1-2-N and N-pieces of the elements (cells) as a whole are coupled to an annular shape to constitute an annular optical resonator in such a manner that the output light of one cell is entered to the next cell. The resonator is so constituted that light E1 is entered to the media 1-1-1-N by reflecting mirrors 2-1-2-N of the respective cells. The flip-flop action which is impossible with the conventional unit element is thereby realized with the assemblage of the cells.

     CONSTITUTION: If the wind intake port 3" of a blower 3 is connected to the flue of, for example, a heavy oil boiler, and the exhasut gas is passed through the branch wind path a 1  on the left side, SOx and NOx in the exhaust gas are adsorbed in an active carbon case 6. When the active carbon in the case 6 are approximately saturated by the adsorbed gas, cylinders 15, 18 are operated to change over the exhaust gas to the other wind path a 2  and the adsorption is continued with the case 6'. During this time, in the case 6 for which the dampers 10, 11 are closed, pulse voltage is applied to electrodes 8, 8... to cause spark discharge among active carbon particles 7, whereby the adsorbed gas is desorbed. Since the desorbed gas of a high concn. is produced in a short time in a dehydrating chamber b of a small volume by the spark discharge, it is taken out through a taken-out port 10 provided to a pipe body 2 and is subjected to suitable treatment.

IPC: B62D5/08
Filed: 1983-02-24
Abstract: PURPOSE:To reduce the hydraulic power generated on the internal leak pressure receiving surface of actuating oil by spacing first and second low pressure grooves at intervals at the radial inner and outer locations that insert the annular groove of a first plate provided at the supply path side of the actuating oil. CONSTITUTION:An annular groove 15 that is connected to the supply path of actuating oil is formed circumferentially on an H surface 13a that is the axial one side end face of a first plate 13. First and second low pressure grooves 35 and 36 are spaced at regular intervals along the annular groove 15 at the radial inner and outer locations that insert the annular groove 15. Since the area of the internal leak pressure receiving surface 37 is reduced in such a degree that these low pressure grooves 35 and 36 are formed, the Galpha and Gbeta generated by the internal leak pressure into the actuating oil alpha and beta directions from the annular groove 15 can be reduced, as compared with the conventional method.

Title: Method and apparatus for plating corrosion-resistant chromium
Inventor: HARADA YOSHIO
IPC: C25D5/04
Filed: 1979-03-15
Abstract: PURPOSE: To form a plated layer of chromium excellent in corrosion resistance and wear resistance on the surface of a material to be treated, by plating the surface of the material to be treated for a prescribed time with the penetrating holes closed, the holes which are made in the coaxial inside and outside cylinders constituting an anode, then by plating for a prescribed time with the holes opened.  
     CONSTITUTION: An inside cylinder 4a and an outside cylinder 4b are combined in such a way that penetrating holes 4c made in both cylinders are not connected. Then movable handles 8 are set on the upper end so that both cylinders may not slip while revolving. Electrolysis is conducted at a required plating temp. and current density while revolving the anode 4 at a prescribed revolution speed. At that time, the temp. of plating soln. 2 in the anode 4 rises with the progress of the electrolysis, hence the first Cr-plated layer excellent in corrosion resistance and of dense crystal structure is formed on the outer peripheral surface of the anode made of a  material to be treated. Then electrolysis is conducted with the holes 4c of the cylinders 4a, 4b connected, so that the temp. in the anode falls to form the second Cr- plated layer of coarse crystal structure and of excellent wear resistance on the first  Cr-plated layer.
