Title: Zoom lens having uv cut element
Inventor: OSHIMA SHIGERU
IPC: G02B15/16
Filed: 1993-05-26
Abstract: PURPOSE:To effectively prevent the degradation in image quality by the chromatic aberrations often generated on a telephotoside at the time of increasing a variable power while having a long focal length and to obtain high performance by providing an optical system with a so-called UV cut element which mostly absorbs the luminous flux of the wavelength shorter than a prescribed wavelength in an adequate position in this element. CONSTITUTION:This zoom lens is formed by setting respective elements in such a manner that the luminous fluxes emitted from a stationary 41st group L41 are made into approximately parallel luminous fluxes. The UV cut element UVF consisting of a parallel flat plate is arranged on the image side surface of the 41st group L41 to regulate the transmission quantity of the luminous fluxes mainly on the short wavelength side of <=430nm to <=10%. The image face side of the 41st group L41 is provided with the UV cut element UVF in such a manner as to decrease the adverse influence, such as chromatic aberrations and particularly the axial chromatic aberrations and color flares of the luminous fluxes on the short wavelength side, generated on the telephoto side at the time of increasing the magnification of the zoom lens, by which the degradation in the optical performance is prevented.

Title: Production of methane
Inventor: ROBIZU HOWAIMAN
IPC: B01J23/46
Filed: 1979-11-16
Abstract: Supported ruthenium metal catalysts prepared by reduction of carbonyl compounds give improved yields of methane in the hydro-cracking of hydrocarbons, especially alkanes and alkyl aromatics. Alkanes may be cracked to methane at low temperatures (200-300 DEG C) and the de-alkylation of alkyl benzenes may be controlled sufficiently to allow removal of isomers e.g. ethylbenzene from xylenes. The novel catalysts comprise ruthenium clusters having average dimensions below 20  ANGSTROM .

Title: Cylinder for vtr
Inventor: KOBAYASHI YOSHISADA
IPC: G11B15/61
Filed: 1983-08-16
Abstract: PURPOSE:To decrease the friction of a tape traveling surface and to improve the slip thereof as well as to improve wear resistance and workability by forming a cylinder body of a composite material consisting of carbon impregnated with an aluminum alloy. CONSTITUTION:A phenolic resin as a binding material is mixed with carbon and such mixture is molded into a cylinder body 1. When the molding is sintered, the resin melts and the sintered body of carbon is produced. A molten aluminum alloy is impregnated with the sintered body to form a composite material. The composite material is worked to form a cylinder body. Since the carbon is contained in the body 1, the fluctuation in friction is less and stable so that a tape traveling surface 2 has 0.15-0.2 coefft. of friction. Since the aluminum alloy is impregnated in the cylinder body, the wear resistance is good and the workability is improved as well.

Abstract: PURPOSE:To easily remove methyl sulfide, etc., which is water-insoluble and hard to be decomposed by biologically by partitioning a filled tank in at least two with different cross section surface area in the gas flow direction at the time deodorization of malodorous gas is carried out by bringing the gas into contact with bacteria which can decompose malodorous components held in the filled tank. CONSTITUTION:A high LV (space linear velocity) filed layer 2 and a low LV filled layer 3 are packed with a sponge packing material to which activated sludge containing bacteria to decompose malodorous components is stuck. After the water receiving part 6 is filled with well water or water treated biologically, water is scattered by a water scattering part by a water circulation pump 7. A malodorous gas is led to each filled layer 2, 3 from a gas introduction part 4 to pass the layers continuously and at first malodorous components which are easy to be solved in water and decomposed by bacteria in the layer 2 and next the malodorous components which are difficult to be solved in water and decomposed biologically are removed in the layer 3. Following the deodorization, since pH of the circulated water is lowered and the concentration of salts increases, water is suppled, NaOH 8 is injected, and circulating water is drawn through drain 9 at proper time.

Title: Feedback clamping circuit
Inventor: HARADA SHIGERU
IPC: H04N5/18
Filed: 1989-06-13
Abstract: PURPOSE:To attain stable clamping operation even when a source such as a VTR and a disk including much noise is used by discriminating digital control code previously included in an input signal and controlling the gain of a feedback loop or a non-sensitive band in accordance with the discriminated output. CONSTITUTION:A discriminating means 20 discriminates a digital control code signal and a gain control means 8 controls the gain of the feedback loop or the non-sensitive band in accordance with the discriminated output. Namely, a gain reducing area or the non-sensitive band is expanded in the case of a code indicating a signal of a low S/N or the gain reducing area or the non- sensitive band is narrowed in the case of a code indicating a signal of a high S/N in accordance with the sort of the input signal. Thereby, even when an input signal including comparatively much noise is inputted, stable clamping operation can be attained without varying clamp potential.
