Title: Oxidization of aromatic compound
Inventor: SASAKI KAZUO
IPC: B01J23/94
Filed: 1989-02-22
Abstract: PURPOSE:To continuously produce an oxidized aromatic compound under mild condition in high efficiency while keeping the activity of an oxidation catalyst in high efficiency by oxidizing an aromatic compound with an O2-containing gas in liquid phase in the presence of a specific oxidation catalyst and a specific reduction catalyst. CONSTITUTION:The objective compound such as phenol is produced by (1) adding an aromatic compound such as benzene to a mixed solvent produced by mixing an acid such as sulfuric acid with a solvent such as acetonitrile containing (A) an oxidation catalyst consisting of copper or a copper compound such as cupric sulfate and (B) a reduction catalyst consisting of a compound capable of reducing cupric ion with H2 gas or a reducing compound having the function comparable to H2 gas (e.g., platinum black deposited on platinum) and (2) oxidizing the aromatic compound at normal temperature -200 deg. while passing CO as a reducing gas and air as an O2-containing gas through the solution. The above oxidation process has merits of low facility and running costs and is suitably applicable for industrial operation.

IPC: G05D7/00
Filed: 1980-04-02
Abstract: PURPOSE: To continuously extract a sludge of a high concentration under a stable condition, by controlling a discharge flow amount of a water separated from a floating sludge on the bases of a sludge flow amount and a sludge concentration, and concentrating the sludge in a pressurized floatation process.  
     CONSTITUTION: When a lower boundary gauge 7 detects the lower surface of a floating sludge zone 6, a controller 10 controls a flow amount control valve 9 so as to decrease the discharge amount of a separated water. When an upper boundary gauge 8 detects the lower surface of the floating sludge zone 6, the discharge amount of the separated water is increased in the same manner. That is, the lower surface of the floating sludge zone 6 is constantly controlled at a level between the lower boundary gauge 7 and the upper boundary gauge 8. Consequently, the lower surface of the floating sludge zone 6 is kept at a predetermined level in a floatation  concentration tank 3, so that the sludge of a high concentration can be continuously  extracted under a stable condition.

Title: Silver complex salt diffusion transfer material
Inventor: OKA SHIYOUJI
IPC: G03C8/06
Filed: 1980-04-03
Abstract: PURPOSE:To form a high contrast image with high reflecting density while using a little silver by adding a colorant such as a pigment which is not discharged or decolored by development or other processing to an image receiving layer by an amount required to well mask the color of an opaque support. CONSTITUTION:For example, support 1 is blackened with carbon black or the like, and a white pigment which contrasts strikingly with support 1 in light and darkness and is not discharged by development or other processing is dispersed in image receiving layer 2 so as to mask the black color of support 1. Soluble silver complex salt is diffusion-transferred to layer 2 from a silver halide emulsion layer and developed to form a silver image as shown by the oblique line part. The part is then removed with an etching bleach bath such as a soln. contg. CuCl2, citric acid and H2O2 to leave layer 2 of the white part, or the silver image part is bleached and tanned by tanning bleach, and the nonimage part is removed to disclose the black support. Thus, an image with sufficiently high density is obtd. while using a small amount (0.15g/m<2> as AgNO3) of silver.

Abstract: PURPOSE:To make it possible to suppress variation in the room pressure caused by pulsating wind pressure outside of a room subjected to ventilation by operating automatically damper devices provided at air flow paths for air intake and for air exhaust by means of a blast pressure sensor. CONSTITUTION:This ventilator is provided with a wind pressure sensor 23 which detects external wind pressures toward the outer wall W which has an air supply galley 1 and an air exhaust gallery 5. Further, to air flow path 24 for outdoor air intake and a air flows path 25 for air exhaust respectively damper devices 26 are provided which are for adjusting air flow path resistance to regulate air flow path by throttling. Furthermore, a system controller 12 incorporates a room pressure stabilizing control device 27 which automatically operates the damper device 26. With this arrangement, when the wind is high and the external wind pressure acting on the gallery faces significantly pulsates, the resistances of the air flow paths 24 and 25 connected to the galleries are made larger by controlling the amount of throttling, and this alleviates variations in the air supply pressure and air exhaust pressure which accompany the variation in the external wind pressure, and it is possible to suppress variation in the room pressure subjected to ventilation.
