Abstract: PROBLEM TO BE SOLVED: To reduce the quantity of injected acid for decarbonation and to enable the prevention of the propagation of bacteria in a system by a method in which COD-containing drainage, after being added with hydrogen peroxide, is oxidized by being irradiated with ultraviolet rays and treated with active carbon. SOLUTION: Hydrogen peroxide is injected into COD-containing drainage, the COD components are oxidation-decomposed by being irradiated with ultraviolet rays. The treated water, after being added with acid, is decoarbonated and then contacted with active carbon to remove residual hydrogen peroxide. Water without COD components, carbonic acid components generated by the decomposition of the COD components, and residual hydrogen peroxide is supplied to a primary water purifying apparatus, etc., as required to be treated further. As drainage applicable to the method, low-TOC drainage such as semiconductor washing drainage and high-TOC drainage such as fuel electrode condensate of a fuel cell are named.

Filed: 1983-08-20
Abstract: PURPOSE:To maintain a uniform distribution of the thickness of the film deposited by evaporation on a wafer with a sputtering device by making a target movable and adjusting and maintaining the distance between the target and the wafer always at a specified distance. CONSTITUTION:An Al target 12 as a raw material for sputtering is placed oppositely to an Si wafer 2 in the stage of sputtering an Al film to the surface of the wafer 2. The target 12 is placed on a cathode 13 integrated with a permanent magnet 14 and is made vertically movable by means of an adjusting screw 15. An anode 11 is provided around the cathode 13 and discharge is generated between the same and the cathode 13 to ionize Ar in an Ar atmosphere. Said ion collides against the target on the cathode and evaporates the target 12 in the form of atom, thereby sputtering and growing the Al film on the Si wafer 2. The target 12 is risen together with the cathode 13 by adjusting the screw 15 with a decrease in the target 12 to maintain always the specified space between the target 12 and the wafer 2. The Al film having a uniform film thickness distribution is thus formed on the entire wafer.

IPC: H04L27/10
Filed: 1992-06-11
Abstract: PURPOSE:To transmit a reset signal for canceling communication error in the case of generating noise or the like in a communication line. CONSTITUTION:A pulse transmitting means 10a provided at a master equipment 10 transmits a pulse at a frequency different from that of digital data signals P0 and P1 as a reset signal PR.

Abstract: PURPOSE:To improve the directivity of a light source, by arranging the light source so that the emitted light is made incident to the edge face of a hollow and columnar transparent matter. CONSTITUTION:The beam made incident to a hollow part through an edge face formed into a rotary hyperboloid or a spherical surface is radiated directly or after a full-reflection on the inner surface through a pipe in the same angle as the angle of radiation of a light emitting diode 6. In the case of a material having a 1.5 refractive index, the beam made incident with 5 deg. to the optical axis has a >=60% full- reflection. The full-reflection quantity increases as the angle decreases. The optical path having a >=psim radiation angle causes refraction by a curved surface and becomes parallel to the optical axis. A rotary hyperboloid is ideal for the curved surface, but a spherical surface is also available if some problem of production arises although some inferiority in its characteristics may be caused.
