IPC: C21B13/00
Filed: 1987-10-27
Abstract: PURPOSE:To extend retaining time in a furnace and to shorten reducing reaction time by attaching an outer part grain circulating device to the fluidized bed reduction furnace and arranging means circulating fluidized gas toward furnace height direction in the furnace. CONSTITUTION:A settling tower 10 of the outer part grain circulating device is connected with the lower part of the fluidized bed reduction furnace 6 and is integratedly constituted with the upper part of the furnace 6 through cyclon. Circulating nozzle group 11 pointing to circumferential direction having about 30-60 deg. angle are arranged above the outlet 20 of the settling tower 10 in the reduction furnace 6 and fluidizing nozzles 12 are arranged near the outlet 21. Fine powdery iron ore is charged into the reduction furnace 6 together with the prescribed raw material and the fluidized bed formed by fluidized gas ascending in the furnace 6.

Title: Multiple image forming device
Inventor: KAWANO YUZO
IPC: G03G15/01
Filed: 1997-10-02
Abstract: PROBLEM TO BE SOLVED: To make the constitution of a color slippage correction means simple and inexpensive, to easily adjust color slippage and to eliminate the slippage of respective pixels by arranging an exposure means so that a photoreceptor is scanned with a prescribed tilt and providing a device with a speed adjustment means changing the respective moving speed of the photoreceptor. SOLUTION: A relative position between the exposure means 3 and the photoreceptor drum 1a is set so that a scanning end point E is set on the more downstream side of the rotating direction of the drum 1a than a scanning start point D. Then the fluctuation rate of an image tilt on an intermediate transfer belt becomes larger in the case the circumferential speed of the drum 1a is low in comparison with the case that the circumferential speed of the drum 1a is high and it is changed in an area where the circumferential speed of the drum 1a is lower than the reference speed. Therefore, the tilt deviation in an oblique direction is adjusted in an area where the load torque of a driving source for moving the drum 1a is small and the adjustment work thereof can be made simple and inexpensive.  Besides, the slippage of the respective pixels occurring when the images obtained by the optical scanning of the plural exposure means are superposed is eliminated. Thus, the high-quality image is obtained.

IPC: G01R33/02
Filed: 1988-10-25
Abstract: PURPOSE:To reduce the power consumption of a magnetic sensor by exciting the sensor with use of burst waves which are made higher in amplitude for the first plural waves, and lower for the succeedings. CONSTITUTION:A magnetic sensor mounted on an unmanned carrier causes an excitation coil 2 to produce an AC magnetic field by supplying drive voltage pulses Vin to a driving source 1 and guides the carrier by detecting deviations from ferrite markers installed along the course of the carrier from the difference between detecting voltages induced in a right and left detecting coils 3 and 3'. When burst waves which are made higher in amplitude for the first plural waves as shown in Fig. (a) are supplied to the excitation coil 2 as the driving voltage Vin, the time during which the detecting voltages of the coils 3 and 3' reach a fixed level can be reduced as shown in Fig. (b). Therefore, the power consumption can be reduced when the duty ratio of the burst waves is set smaller.

Title: Thermal recorder
Inventor: TANAKA HIDEFUMI
IPC: B41J2/36
Filed: 1987-10-28
Abstract: PURPOSE:To contrive a higher recording speed, by controlling energization on the basis of a constantly fixed unit energization section so as to gradually increase the apparent density of recorded images. CONSTITUTION:The first gradation is formed by use of an initial energization section TS. Each of the 2nd to 10th gradations is formed by use of unit energization sections T with equal time intervals. For the 2nd gradation, the actual energization time in the unit energization section extends over the entire range of the unit energization time T, namely, from beginning to end of the section. On the other hand, for the 3rd and latter gradations, the actual energization times are made to be substantially shorter by providing respective rest times t3-t10 in the respective unit energization times T. When one unit energization time is thus added for each one gradation increase, the increase in apparent density and the increase in the gradation are proportional to each other.
