Title: Two-color electrophotographic recorder
Inventor: FURUTA HIDEYA
IPC: G03G15/01
Filed: 1982-12-09
Abstract: PURPOSE:To form a two-color electrophotographic recorder which is small in size and simple in construction and is inexpensive by providing a single exposing light source which can emit selectively light of specific colors A and B on a scanning line, as an exposing means. CONSTITUTION:The surface of a photosensitive body is electrostatically charged to respectively reversed polarities by a primary charger 1 and a secondary charger 2, then irradiated with two-color images of red and black thereon by an image exposing optical system 3. Two kinds of electrostatic latent images; the positive latent image for the red image and the negative latent image for the black image having the polarities reverse to each other, are thus formed. An exposing optical system 4 for optical writing has an LED array 11 of a variable emitted light color type and a lens array 12 such as a focusing optical transmission body. The LED array 11 is capable of emitting selectively red color light (specific color A) or the green light (specific color B) for the black image according to the value of the current to be conducted.

Title: Production of activated carbon
Inventor: SUZUKI MITSUO
IPC: B01J35/02
Filed: 1996-07-29
Abstract: PROBLEM TO BE SOLVED: To obtain an activated carbon with a significantly improved removal activity of harmful substance in water or gas by adding titanium and/or a titanium compound in a preactivation stage when producing the activated carbon. SOLUTION: A feedstock charcoal is finely crushed and this crushed charcoal is kneaded with a binder, granulated and hardened and carbonized. The granules are activated as a granular activated carbon. In this case, titanium or a titanium compound (except titanium dioxide) is added in a stage before activation, preferably before the carbonization step. If the titanium compound is added at this specific point of time, the activated carbon containing the anatase-type or the rutile-type TiO2 of extremely small grain diameter with high photocatalytic activity is obtained after the activation step. The activated carbon thus obtained has titanium dioxide anchored in the activated carbon particle so that the titanium dioxide is hardly discrete from the carbon particle and consequently, the removal activity of foreign matter is enhanced.

Abstract: PROBLEM TO BE SOLVED: To facilitate the operation of a user by storing a resolution when a read means reads an original and storing a resolution for transmission in accordance with whether the original is a color original or a black/white original. SOLUTION: In the case of copying, an original is placed on a sheet scanner 112, a copy button of an operation section 16 is depressed to select a color original or a black/white original.

Abstract: PURPOSE:To enable high-precision control at low cost by providing a configuration of a plurality of flipflop circuits which delay a write signal and a gate circuit which performs logic operation on an output of the flipflop circuits and outputs the operational results, and providing a write duty control circuit. CONSTITUTION:A write duty control circuit provided in a video controller is composed of four flipflop circuits (FF) 60-63, two inverters 64, 65 and two NAND gates 66, 67 which are gate circuits. FF's 60, 61 delay an input signal, synchronized to a write clock WCLK, while FF's 62, 63 delay an input signal synchronously with a reference clock CLOK. Next, the logic calculation of each output is performed by means of NAND gates 66, 67. An output signal OUT2 in response to a write signal WDATA indicates a pulse width at low level which is smaller by a single period T of the reference clock CLOK. Thus it is possible to generate a delay time based on the half period of the reference clock CLOK as a minimum unit.
