Title: Method for adjusting sulfite concentration
Inventor: SHINODA NAOHARU
IPC: C01B17/775
Filed: 1984-04-20
Abstract: PURPOSE:To keep the concentration of the residual sulfites in a product sulfate at a desired low value rapidly and economically in spite of variation in load, by measuring the sulfite concentration in an absorbing solution continuously to adjust the amount of an oxidizing agent, etc. to be fed on the basis of the measured value. CONSTITUTION:A waste gas 100, containing SO2, and fed to the body of an absorption column 101 is brought into contact with an absorbing solution to remove the SO2, and the resultant gas is discharged as a purified gas 102 to the outside of the column 101. On the other hand, the absorbing solution, formed by absorbing the SO2, and containing sulfites is dropped into a tank 103, brought into contact with air (oxidizing agent) fed from nozzles 107, oxidation catalyst fed from a pipe 108 and CaCO3 fed from a pipe 106 and neutralized. The sulfites are simultaneously oxidized into sulfates, which are passed through a centrifuge 119 to take out by-product gypsum 120. In the above-mentioned method, the sulfite concentration in the absorbing solution in the tank 103 is measured by a sulfite concentration detector 109, and the amount of the air and/or oxidation catalyst is controlled to adjust the resultant measured values to the set value. (Symbols 111 and 112 are controllers.)

Title: Cornering ramp system for vehicle
Inventor: SHIBATA HIROMI
IPC: B60Q1/18
Filed: 1993-03-16
Abstract: PURPOSE:To enable application to the whole kinds of vehicles with no change made in coping with an illuminating angle, and also with an identical system configuration kept on. CONSTITUTION:A rotating angular velocity is detected by an angular velocity sensor 1 when a vehicle is running on a curved road. The vehicle speed is detected by counting pulses from a distance sensor 2. Angular velocity data and vehicle speed data are latched by a latch circuit 5 and a latch clock 6. Angular velocity data is divided by vehicle speed data by a divider 8, so that the inverse number of a turning radius is directly computed. Namely, operations where a turning radius is obtained by dividing vehicle speed data by angular velocity data so as to allow the inverse number of the turning radius to be computed, are substantially performed. An illuminating angle can be approximated as the simple inverse from of the turning radius. As attention is paid to the aforesaid fact, an objective position of the illuminating angle as the inverse function of the turning radius is obtained, the present position of the illuminating angle of a headlamp is thereby controlled to coincide with the objective position.
