Title: Recoverying method for silica from geothermal water
Inventor: ONODA TAMOTSU
IPC: C02F5/02
Filed: 1986-08-30
Abstract: PURPOSE:To produce SiO2 having high purity stably by depositing dissolved SiO2 in geothermal water by adding polyethyleneimine to the water, then removing polyethyleneimine by thermal decomposition. CONSTITUTION:Since a large amt. of SiO2 is dissolved in the geothermal water generated in a geothermal power plant, etc., polyethyleneimine having 500-1,000,000mol.wt. is added to the geothermal water in the form of aq. soln. of 10-1,000ppm concn. to cause deposition of dissolved SiO2 in the form of fine particles having 0.02mum particle size. Deposited fine SiO2 particles coagulate and precipitate in the form of coarse massive gel having ca. 0.5-1.0cm particle size. The precipitated SiO2 particles are washed with water and separated by filtration repeatedly, then heated for about 2hr at >=600 deg.C to remove remaining polyethyleneimine by thermal decomposition. Thus, SiO2 having 97-98% purity expressed in terms of pure SiO2 content is stably produced.

Title: Engine speed signal detection method
Inventor: IMAMIYA TAKAHIDE
IPC: F02D45/00
Filed: 1993-08-17
Abstract: PURPOSE:To prevent engine speed from being mis-calculated due to external noise by providing a judgement block and detecting only an edge inputted into the judgement block as NE signal in a method for detecting the edge, when inputted, as engine speed (NE) signal. CONSTITUTION:When a fall edge is inputted and NE interruption occurs, the fall edge is judged to be external noise and not detected while a gate signal is turned on. When the gate signal is turned off, the fall edge is judged to be the fall edge of the NE signal, and the judgement time (judgement block) according to the engine speed is calculated based on a map. Next, when the fall edge is the edge inputted from a time at which the gate signal is turned off within the judgement time, a preceding time at which interruption occurred is deducted from this interruption occurrence time so as to calculate the latest frequency of the engine speed signal.

Abstract: PURPOSE:To enable the discrimination of whether photosensitive materials having photosensitive layers existing on both surfaces or not and to enable the adequate replenishing of a processing liquid by providing a transporting route for the photosensitive materials with a photosensitive layer surface detecting means. CONSTITUTION:The front surface of a body case 100 of a developing tank 1 is provided with a feed tray 4 to be mounted with a printing plate P. Optical sensors 40a, 40b are disposed on this feed tray 4. The optical sensor 40b detects whether there is the photosensitive layer on the rear surface of the printing plate P or not. The optical sensor 40a detects the transverse size of the printing plate P. The area of the printing plate P is calculated in accordance with the result of the detection by the sensor 40a. Whether the printing plate P is a both side printing plate or not is discriminated by the result of the detection of the sensor 40b. The area of twice the calculated area of the printing plate P is added to the cumulative area and the fresh cumulative area is determined when the printing plate P is the both side printing plate. As a result, the developer of the volume twice the volume in the case of the single side printing plate is eventually replenished when the double side printing plate is to be developed.

Title: Titanium alloy excellent in corrosion resistance
Inventor: MITSUYOSHI SUKEHIRO
IPC: C22C14/00
Filed: 1991-07-19
Abstract: PURPOSE:To provide a corrosion resisting material showing superior corrosion resistance even under an extremely severe corrosive environment of nonoxidizing acid containing oxidizing agent and also excellent in workability and economical efficiency. CONSTITUTION:A titanium alloy having a composition consisting of, by weight, 10-40% Mo, 0.1-15% Cr, and the balance Ti with inevitable impurities and excellent in corrosion resistance and a titanium alloy having a composition further containing, besides the above, 0.01-2.0%, in total, of Ru, Ir, Os, Pd, Pt, and Rh and excellent similarly in corrosion resistance is provided. Although a protective film in which Mo is concentrated is formed on the surface of the material by the addition of Mo and corrosion resistance in a nonoxidizing acid, such as hydrochloric acid and sulfuric acid, can be remarkably improved, the addition of Mo alone cannot prevent remarkable deterioration in corrosion resistance caused by the elution of Mo when an oxidizing agent of about several parts per million exists in the environment. In order to prevent the above-mentioned deterioration in corrosion resistance, further addition of Cr is required. By adding Cr, the elution of Mo can be inihibited and deterioration in corrosion resistance due to the existence of oxidizing agent in the environment can be prevented. Corrosion resistance can be improved to a greater extent by the addition of platinum group elements.
