Title: Angular accelerometer
Inventor: ONISHI KOHEI
IPC: G01P15/16
Filed: 1988-03-04
Abstract: PURPOSE:To obtain accurate angular acceleration with good frequency characteristics without being affected by temperature and noise by differentiating and integrating the voltages of two power generating coils which are induced at different timing by the rotation of a rotor according to the rotation angle position of the rotor. CONSTITUTION:A rotary encoder (RE) 1 detects the rotation angle theta position of the rotor 4a of a rotating machine. A power generator 2 is equipped with two power generating coils 2a and 2b, which are arranged at fixed positions facing a magnet 2c fitted on the side of the rotor 4a while shifting by 90 deg. in the rotating direction of the magnet 2c. The voltages Va and Vb which are induced at the power generating coils 2a and 2b are Va=omegacostheta and Vb=omegasintheta, where omega is the rotating speed of the rotor 4a. The rotation angle position thetaof the rotor 4a which is detected by the RE 1 and the induced voltages Va and Vb of the power generating coils 2a and 2b are inputted to an arithmetic circuit 3. The arithmetic circuit 3 substitutes those values in a=costheta.dVa/dt+ sintheta.dVb/dt to calculate the angular acceleration (a).

Abstract: PROBLEM TO BE SOLVED: To start a reading operation at optimum timing, to prevent a time loss and to improve productivity by starting the conveyance of an original at timing before a specified time from the completion time of the preparatory operation of a reading means, based on an operation condition. SOLUTION: A conveyance time t1 required to carry the original up to a reading position from an original stand-by position is calculated from the operation condition set by a final control element 1. When mag >= 1 is obtained, t1 = T1A + fladjust/(FS2/(mag + magadjust)) is set. When mag < 1 is obtained, t1 = T1B + fladjust/(FS2/(mag + magadjust)) is set. Where, mag, magadjust and fladjust are internal parameters storing reading magnification, a magnification correction value and a conveyance distance correction value which are received from the final control element 1 respectively and T1A and T1B are constants for showing unmagnified and half conveyance times, when an original conveyance distance is at a standard value, respectively.

Title: Method of controlling air-fuel ratio for internal- combustion engine
Inventor: ABE SHINICHI
IPC: F02D41/14
Filed: 1984-03-16
Abstract: PURPOSE:To enhance the economy of fuel consumption, by preventing the air-fuel ratio from shifting from a stoichiometric air-fuel ratio caused by changes in environment, aging effect, etc., and as well by introducing EGR only during feed-back control operation. CONSTITUTION:When the averaged value of compensating coefficients for feed-back control of air-fuel ratio exceeds a value in a predetermined range due to aging effect, etc. (when the mixture becomes leaner than a stroichiometric mixture), a learning value is made large to increase the amount of fuel injection, and therefore, control is made such that the averaged value of compensating coefficients for feed-back control is made small. When the averaged value of compensating coefficients for feed-back control becomes lower than the value in the predetermined range, the learning value is made small to decrease the amount of fuel injection. That is, learning control is made to adjust the averaged value of compensating coefficients for feed-back control within the predetermined range in order to control the mixture so that the latter has a stoichiometric air-fuel ratio. Upon steady state operation the feed-back control is interrupted to stop exhaust recirculation, but during feed-back control operation exhaust gas is recirculated to the intake-air system.

Abstract: PROBLEM TO BE SOLVED: To enable a semiconductor wafer to be uniformly polished and enhanced in polish throughput by a method wherein a slurry path is carefully provided to the outer edge of a wafer support, and a flow of slurry applied to an interface between the wafer and a pad is enhanced in flow rate.
