Title: Method of controlling rotational speed of internal-combustion engine
Inventor: ISOBE TOSHIAKI
IPC: F02D31/00
Filed: 1983-07-12
Abstract: PURPOSE:To prevent drop of an engine rotational speed at transition and smoothly decrease the rotational speed to a target rotational speed, by controlling an amount of air bypassing a throttle valve upon receiving a load to increase the amount of air over a target amount, and decreasing the amount of air to the target amount with a reduction rate increased. CONSTITUTION:A target rotational speed NF according to an operational condition and an estimated duty ratio De according to an amount of air are set. When an ISC timing is reached, an average value NE of an engine rotational speed is calculated, and a basic duty ratio Do for feedback controlling the average value NE to the target value NF is calculated. When a load is received, the estimated duty ratio De for feedforward control is added to the basic duty ratio Do to determine a control duty ratio D. An opening degree of an ISC valve is controlled by the control duty ratio D so that the average value of the engine rotational speed may become the target rotational speed.

Title: Silver-colored glaze for earthenware tile and production thereof
Inventor: MITSUI YASUSHI
IPC: C04B41/50
Filed: 1988-05-24
Abstract: PURPOSE:To produce silver-colored glaze under stable calcining conditions and to make it possible to simultaneously calcine a tile coated with the glaze and a tile coated with glaze of a different kind by using Mn2O3 and/or Mn3O4 as starting material for an Mn component among starting materials for glaze for a silver-colored tile contg. a large amt. of the Mn component. CONSTITUTION:In silver-colored glaze for an earthenware tile contg. MnO when expressed by the Seger method, Mn2O3 and/or Mn3O4 is used as Mn-contg. starting material. Since MnO2 is not used, an endo-thermic reaction does not take place during calcining and calcining can be carried out at 1,060-1,140 deg.C. The resulting glaze produces the conventional silver color developing effect.

Filed: 1989-05-19
Abstract: PURPOSE:To reduce the overshoot of a real head speed at the switch between the deceleration and the acceleration by changing the gain of a speed control loop in accordance with the difference of the real and target speeds of a head. CONSTITUTION:A loop gain changing device 4 outputs the loop gain accordant with the difference between a target speed obtained from a speed profile generator 2 and a real head speed outputted from an electronic tachometer 11 to an (a) contact of a mode switch 1. The output obtained from an adding point 3, i.e., the speed difference is inputted to a coefficient unit 21 and also to one of both input terminals of a multiplier 22. At the same time, the output of the unit 21 is inputted to the other input terminal of the multiplier 22 and also outputted to an adding point 23. Then the output of the unit 21 is added to the output of the multiplier 22 at the point 23 and outputted toward the switch 1. If the input and the output are referred to as A and B, the gain B/A changes in response to the value of A, i.e., the speed difference. As a result, the overshoot of the head speed can be suppressed to the target speed.

Abstract: PURPOSE:To eliminate measurement errors by a method where an alternating magnetic field is intermittently applied to an excitation electric coil to measure an electrochemical voltage from a voltage between electrodes, thereby monitoring a flow rate from the voltage between electrodes and electrochemical voltage by holding the magnetic field. CONSTITUTION:When a liquid is conveyed in a passage, a control signal is outputted to an excitation circuit and an alternating magnetic field is intermittently applied to an excitation coil by holding the alternating magnetic field to generate alternating magnetic field parts A1, A2,-An and magnetic field holding parts B1, B2-Bn, a voltage between electrodes is generated. Voltages V1 and V2 between electrodes are sampled from the parts, where the influence of transient response voltage in the alternating field parts is small, in accordance with a sampling signal from an MPU circuit to be summed with each other. The sum is two times the electrochemical voltage V0 so that an electrochemical voltage V0' is measured as (V1+V2)/2 at that time. By using the voltage V0', a voltage V3 in the magnetic holding part B1 where the transient response voltage does not exist is sampled so that a voltage V3-V0' is calculated and outputted as a flow rate signal.
