Title: Denitrification device
Inventor: YAMAGUCHI FUMIHIKO
IPC: B01D53/94
Filed: 1997-04-30
Abstract: PROBLEM TO BE SOLVED: To enable the oxidation of SO2 contained in an exhaust gas into SO3 to be inhibited by applying a substance which diminishes the oxidation properties of a metallic oxide sticking to a denitrification catalyst to the upstream side part of the denitrification catalyst. SOLUTION: As illustrated on the illustration, i.e., the expanded lateral view sketch of part 4 of a denitrification catalyst, a substance which inhibits the oxidation properties of a metallic oxide such as vanadium oxide sticking to the denitirication catalyst, for example, an oxide of silica(Si), molybdenum(Mo) or arsenic(As) or carbon is coated on the surface of the upstream side part 4a of the denitrification catalyst. In addition, the length(Y) of the upstream side part 4a on which the metallic oxide of silica or molybdenum or carbon is coated is set to be 1/2 or less of the length (X) of the whole denitrification catalyst (i.e., 4) (i.e., constituted to be Y<1/2X). Thus it is possible to significantly inhibit the oxidation of SO2 contained in an exhaust gas into SO3 .

Title: Cylindrical nickel-cadmium storage battery
Inventor: KATSUMATA ICHIRO
IPC: H01M50/562
Filed: 1988-05-11
Abstract: PURPOSE:To increase the welding strength between a terminal plate and terminals and to improve the work efficiency by welding the tub terminal plate in which a slit hole is formed at the center of the weld with cell terminals in the longitudinal direction, to the terminals at the upper and the lower sides of the cell. CONSTITUTION:At the center of the weld 14 of a tub terminal plate 12, a slit hole 13 is engraved in the longitudinal direction of the terminal plate. When the welding is carried out, the welding current flowing from an electrode 15 flows through the tub terminal plate 12 and a sealing plate 18 of the cell shown as 17, and flows back to an electrode 16 through the tub terminal plate 12 and 17. In this case, since the resistance of the connection 19 between the terminal plate 12 and the sealing plate 18 is large, the welding current generates heat and welds there, and the welding is utilized effectively. Consequently, the welding strength between the terminal plate and the terminals can be improved.

Title: Indirectly-heated cathode heater
Inventor: HAGIWARA HEIICHI
IPC: C25F3/08
Filed: 1983-06-27
Abstract: PURPOSE:To stably and easily obtain an indirectly-heated cathode heater which dissipates a low power and starts quickly by electroanalyzing a heater foot end with no electric field applied in an electrolyte which selectively dissolves only an Mo wire with an electric field for electroanalysis applied but does not dissolve either a W wire or an Mo wire with no electric field applied. CONSTITUTION:A W.Re alloy wire is formed in a combined winding of condensation and rarefaction with an Mo wire serving as a mandrel, then it is formed in a double helical winding to form a heater. Next, after performing processes such as forming, annealing, and alumina coat sintering on the secondary coil section 3, an adequate number of them are clipped and immersed in an electrolyte up to a position 8 to selectively electroanalyze only Mo. In this case, an electrolyte is used which does not dissolve W and Mo with no electric field applied but selectively dissolves only Mo with an electric field applied. 85% concentrated sulfuric acid or an aqueous solution of 15g/l of sulfanic acid+ 30g/l of chromic acid, for example, can attain this purpose.

Title: Method for evaluating lithium niobate membrane and apparatus for preparing the same
Inventor: MATSUNAGA HIRONORI
IPC: C30B29/30
Filed: 1990-04-27
Abstract: PURPOSE:To rapidly set the film forming condition of a membrane with a stoichiometric ratio composition (Li/Nb=1) by evaluating a compositional ratio Li/Nb using the light absorbing end wavelength measured using an LiNbO3 membrane. CONSTITUTION:A vacuum chamber 20 is set to a film forming state to set a Knudsen cell 2(Li) and an electron beam heating evaporation source 1 (Nb) to a definite evaporation state. Both shutters 5 are opened to perform the simultaneous vapor deposition of Li and Nb on a monitoring quartz plate 13. The light from a light source 12 is transmitted through the quartz plate 13 during this vapor deposition and the light absorbing end wavelength of the membrane during membrane formation is measured by a spectrophotometer 14 capable of performing measurement over a range from a visible region to an ultraviolet region. Next, the output of the power controller 16 of the evaporation source 1 is controlled by a computer 15 to increase and decrease an emission current and the membrane is formed so as to enter the range of about 310 - 320nm being the light absorbing end wavelength of the stoichiometric ratio composition of LiNbO3. The film forming conditions of the evaporation source 1 and the Knudsen cell 2 are held and a shutter 6 is opened to accumulate the membrane on a substrate 4.

Title: Rotary disc supporting mechanism for watt-hour meter
Inventor: SHIMOE TOSHIHIRO
IPC: G01R11/12
Filed: 1983-06-23
Abstract: PURPOSE:To stabilize the torque with the passage of time by providing an engaging mechanism between the rotating shaft of a rotary disc and the rotation support shaft thereof to check the relative rotation of both the shafts so that the rotary disc always rotates supported with a rolling mechanism. CONSTITUTION:A hexagonal hole 13a is formed at the other end of a rotating shaft 5 following a hole 11 while hexagonal surface 13b is formed on the periphery of the base of a small-diameter projection 12 in a rotation supporting shaft 7 so that the small-diameter projection 12 is fitted into the hole 11 while the hexagonal surface 13b is fitted into the hexagonal hole 13a. As the relative rotation between the rotation shaft 5 and the rotation supporting shaft 7 is checked with an engaging mechanism 13 comprising these hexagonal hole 13a and the hexagonal surface 13b, the rotation of the rotary disc 4 is supported with a guide pin 10 and a rolling mechanism 6 regardless of a lateral thrust and a parastic oscillation thereof. This eliminates variation in the friction torque at the rotation supporting part of the rotary disc during the rotation thereof thereby stabilizing the torque with the passage of time.

Abstract: PURPOSE:To prevent the back of a transfer sheet from being soiled by providing a sheet transfer bias roller and a roller cleaning blade, which cleans the sheet transfer bias roller, on the same member so that their positional relationship is constant. CONSTITUTION:The sheet transfer bias roller 23-1 and the roller cleaning blade 50-4 both are provided on the upper bracket 23-4, and their positional relationship is invariable irrespective of a change in position of the upper bracket 23-4. Therefore, even when the upper bracket 23-4 and the lower bracket 23-5 shake because of the rotation of an eccentric cam 51-1, this relationship does not change and the roller cleaning blade 50-4 is always in contact with the sheet transfer bias roller 23-1 under the satisfactory conditions, and since the sheet transfer bias roller 23-1 is rotated all the time, toner on the roller is satisfactorily removed. Thus, the surface of the sheet transfer bias roller 23-1 is always cleaned and soiling of the back of a transfer sheet is eliminated.
