Title: Desulfurization in furnace
Inventor: MIURA YOSHIMASA
IPC: F23C7/00
Filed: 1989-07-28
Abstract: PURPOSE:To raise the efficiency of desulfurization by charging a desulfurizing agent in Ca family into a furnace to effect the first stage of desulfurization reaction and cathcing fly ash that contains waste desulfurizing agent from the exhaust gas and adding to it an acid to give rise to a neutralization reaction and activate the waste desulfurizing agent and carrying out the second stage of desulfurization reaction. CONSTITUTION:A desulfurizing agent in Ca family is charged directly into a fired furnace to carry out the first stage of desulfurization in the fired furnace. After the ordinary first stage desulfurization the fly ash that contains the desulfu rizing agent is caught from the exhaust gas, and when an acid is added to the caught fly ash, the waste desulfurizing agent is activated through the neutral ization reaction of at least part of CaO or CaCO3//in the waster desulfurizing agent. The ash that contains activated waste desulfurizing agent that is obtained is recycled in the fired furnace or in the flue to have the second stage of desulfurization reaction. It is, therefore, possible to save much of the supply amount of the desulfurizing agent and, further, to achieve a high desulfurization rate over 90% at the ratio, 2 of desulfurizing agent supply quantity to the sulfur equivalent weight.

Abstract: PURPOSE:To measure the width-directional thickness distribution of a sheet to be measured with high accuracy by finding a distribution of intervals between a guide member and a light shield plate in the absence of the sheet to be measured and in a state wherein the sheet to be measured is brought into contact with the guide member. CONSTITUTION:While the sheet 3 to be measured is absent on a rotary shaft 1, the gap width between the light shield plate 2 and shaft 1 in the long-axis direction of the shaft 1 is measured and stored. Then the sheet 3 is brought into contact with the shaft 1, which is rotated to convey the sheet 3 and a heat part 17 is moved reciprocally in the long-axis direction of the area of the shaft 1 simultaneously to measure the thickness distribution of the sheet 3. At this time, the distribution of the interval between the shaft 1 and plate 2 is measured and the secular change between the shaft 1 and plate 2 is detected from the distribution of the gap and the previously stored gap width. The distribution of the interval between the sheet 3 and plate 2 is corrected according to the secular change to measure the thickness of the sheet 3 with high accuracy.

The fiber axis of the optical fiber 4 for projection is slanted at a specific tilt angle alpha to the rotary code disk 3, and its end surface is beveled at a constant tilt angle beta to the fiber axis; and the tilt angles alpha and beta are so set that projection light is refracted by the slanting surface and passed through a slit to enter a photodetecting element. Light parallel to the axis of the projection fiber 4 is sectionally elliptic having a long diameter d1 and d2 after being refracted. Consequently, slits 2 are formed so that their width is equalized to the short diameter d2.

Abstract: PURPOSE:To simplify the circuitry, by arranging a half-wave rectifying circuit, a smoothing circuit and an integration circuit with the discharge resistance/ charge resistance of a smoothing circuit set at 3.5-4.5 to make resistance values less than the input impedance of a first operational amplifier. CONSTITUTION:A diode D1 is connected between an inversion input (negative) terminal and an output terminal 5 of a first operational amplifier M1 to form a half-wave rectifying circuit 1 and a smoothing circuit 2 is made up of a charge resistance R1 for smoothing the output thereof 1, a smoothing capacitor C1 and a discharge resistance R2. With this discharge resistance R2 as input resistance, a feedback resistance R3 and an integration capacitor C2 are connected in parallel between an inversion input terminal 6 and an output terminal 7 of a second operational amplifier M2 to form an integration circuit 3. Then, the ratio R2/R1 between the discharge resistance R2 and the charge resistance R1 in the smoothing circuit 2 is set at 3.5-4.5 to make both the resistances less than the input impedance of the first amplifier M1. Thus, direct current can be outputted in an approximate proportion to a distorted input AC voltage or the like.

Title: Display controller for room heater
Inventor: KASADA TOSHIO
IPC: F23N5/26
Filed: 1989-07-31
Abstract: PURPOSE:To improve simplified operability of display by displaying predetermined residual operation time until an automatic stopper is operated in a different mode from a normal lighting display of an operation indicating lamp. CONSTITUTION:When the value of a timer, i.e., residual operation time becomes, for example, 60 min, an operation display lamp 2 is altered from normal lighting to blinking, and again varied to lighting. In this case, time becoming a reference of blinking period is formed by a microcomputer 9. When the residual time becomes 30min, the lamp 2 repeatedly flashes in a shorter period than the previous period. When the residual time further becomes 10min, the lamp 2 flashes in much shorter period. Thus, a user can know the residual time only by the period of the flashing of the lamp 2 to reduce its cost, thereby improving its operability.
