Title: Operating method of blast furnace
Inventor: NOMURA MAKOTO
IPC: C21B5/00
Filed: 1982-06-03
Abstract: PURPOSE:To maintain the stable operation of a blast furnace by preparing beforehand a number of charging patterns indicating the ore/coke distribution differing in the direction along the circumference of the furnace and estimating the charging pattern which reduces the abnormality in the furnace condition. CONSTITUTION:Charging patterns A-D showing the ore/coke distributions differing in the direction along the circumference of a furnace are prepared by combining the selection of bunkers and the conditions for the swiveling directions and swiveling speeds of a swiveling chute. The patterns A and B or C and D are used alternately by a number of charges in the steady operation to prevent the deviation in the ore/coke (O/C) distribution. If any furnace wall brick is damaged, the charging pattern by which the O/C ratio in said region is increased is assigned to suppress the elevation of the temp. in said region. If the furnace wall is stuck with any deposit, the charging pattern by which the O/C ratio in said region is decreased is assigned to elevate the temp.

Title: Picture rotating device
Inventor: IWASAKI KAZUYA
IPC: H04N5/253
Filed: 1984-05-10
Abstract: PURPOSE:To rotate a video through an external operation without rotating a photographing film by comparing an output of a variable control means for outputting a level signal in accordance with the desired rotational angle of a display picture with an output of a variable control means for outputting said signal so as to control a rotational angle of an image pickup device. CONSTITUTION:When a video on a display screen is rotated through an external operation, a variable control means 20 outputs a signal V1 in accordance with the rotational angle. A variable means 21 is linked with a rotational shaft of an image pickup device, detects the rotational angle of the image pickup device, and outputs a signal V2. The voltage level signal V2 is compared with said signal V1 by comparators 22 and 23. Namely, the angle where an operator wants to rotate a video on a display screen is compared with the current rotational angle of the image pickup device, and by the compared output, the rotational angle of the image pickup device is controlled. If there is a difference between input voltage levels of two comparators, the difference output operates a motor drive circuit 24, and then rotates the video by desired angle.

IPC: G06F3/041
Filed: 1987-04-16
Abstract: PURPOSE:To attain the state detection of a position indicator and the position detecting with high accuracy by detecting a maximum value of an induced voltage excited inversely from the resonance circuit of the position indicator and its attenuation while lots of loop coils radiate a radio wave so as to improve the operability. CONSTITUTION:A processing unit 7 of a position detector 1 supplies a prescribed frequency AC signal to a loop coil 11-1 at first from a transmission circuit 5 and the 11-1 radiates a radio wave by the current flowing therethrough. The radio wave excites the coil of a tuning circuit 41 of the position indicator 4 to induce an induced voltage synchronously with the AC signal to the circuit 41. Then the coil 11-1 is connected to a reception circuit 6 by a transmission/reception changeover circuit 3 and excited inversly by the induced voltage of the indicator 4 to generate the induced voltage attenuated gradually in the same frequency. The transmission/reception of the radio wave is repeated sequentially by switching the loop coil, and the induced voltage is increased as the distance between both the coils is smaller. Each voltage is calculated by the unit 7 and the coordinate of the position giving a maximum value is obtained as a designated position. Moreover, the state of the indicator 4 is identified by the change in the attenuation of the induced voltage.

In this regard, when determining both its shapes, they are determined by executing an evaluation of an astigmatism with regard to a beam passing through an eye-ball winding midpoint of an eye for wearing the lens. By grasping the progressing refractive surface as one function, its surface shape becomes smooth, the astigmatism can be decreased, a shake of an image can be suppressed remarkably, and also a new evaluating method which is called a spherical aberration spot method is utilized for evaluating a shape of an image. This spherical aberration spot method is a method for making parallel rays incident on the whole surface of a lens L to be inspected, and seeing a spot diaphragm of its rays at a place of a prescribed distance P' from the rear surface of the lens. In this way, a shake of an image is decreased remarkably, also the astigmatism of the peripheral part is reduced, and a wearing sense and a use sense of the titled lens become better.

Abstract: PURPOSE:To prepare deliciously cooked rice in a short time, by applying high electric power to the cooking heater immediately after the start of the cooking operation, thereby carrying out the cooking procedure comprising the heating of water and rice in the inner pot, and interrupting the supply of electric power in the course of the above process for an interval defined by the amount of the rice to be cooked. CONSTITUTION:The cooking process comprising the heating of water and rice in the inner pot 2 is carried out by applying high electric power to the cooking heater 4 immediately after the start of the cooking operation. In the cource of the cooking process, the supply of electric power is interrupted for an interval defined by the amount of the rice to be cooked. Water is absorbed to the rice by this procedure. The interval for the absorption of water to the rice is made equal to the time required to decrease the temperature of the rice from the first prescribed temperature attained by applying high electric power to the heater 4 for a definite time interval to the second prescribed temperature. The cooking time can be shortened compared with the conventional process comprising the cooking process after the water-absorption step, and furthermore, the deliciousness of the obtained cooked rice is comparable to that of the rice cooked by conventional process.

Title: Method and apparatus for magnetic field treatment of combustion fluid
Inventor: HASHIMOTO TAKESHI
IPC: F23K5/08
Filed: 1985-05-02
Abstract: PURPOSE:To reform a combustion fluid by a quick-acting magnetic field treatment by flowing vertically and bilaterally asymmetric pulse current through a coil. CONSTITUTION:The input AC voltage of AC power source 6 is converted into about double DC current in a voltage multiplying rectifier 3 and charged to a condenser C2. When the trigger pulse of a relaxation oscillator 5 is applied between gate cathode of a thyrister 4, the charge of the condenser C2 is discharged from a coil 1 through the thyrister 4. The current waveform in the coil 1 becomes a vertically and bilaterally asymmetric impulse form and a magnetic field corresponding to the current waveform is generated in the coil 1. In case where the rising and trailing angles of the magnetic field are steep and the magnetic field varying with time is acted on a combustion fluid, the molecules of the fluid are moved so as to be aligned to the direction of the magnetic field, and upon application of the magnetic field, the magnetic moment of the molecules is intricately varied with changing the magnetic field. Collision and friction are repeated between the molecules and the molecules are divided into fine sections, and therefore, quick-acting reforming of combustion fluid can be attained.
