Abstract: PURPOSE:To optimize a gas flow distribution in the furnace radial direction and to stabilize furnace condition of a blast furnace by controlling a ratio of a descending speed of charging raw materials at the peripheral part to a descending speed of all charge of bell-less blast furnace with a designated value. CONSTITUTION:In operation of the blast furnace 1 with bell-less type raw materials charging apparatus, the descending speed of charging raw materials at the peripheral part in the furnace and the descending speed of all the charge are measured by sounding, and the ascending gas speed in the furnace is adjusted to optimize the ratio of both the descending speeds.

Abstract: PURPOSE:To perform the measurement of an image with high resolution by the use of an ordinary TV camera at low cost by obtaining the mean density of each picture element of a picture element signal which is a video signal and adjacent picture elements and setting the obtained density as insertion data. CONSTITUTION:A measured object OB is captured with a video camera TC in broadcasting standard and the picture element signal obtained by AD- converting the video signal Vs is inputted in an insertion data arithmetic operation part NC.

Title: X-ray device
Inventor: FURUYAMA MAKOTO
IPC: H05G1/66
Filed: 1995-03-31
Abstract: PURPOSE: To lengthen the life of a rotation anode X-ray tube by maintaining a rotary anode at a high speed rotation state during a series of radiography period, and stopping the rotary anode quickly after the termination of the series of radiography period. CONSTITUTION: When a radiography operation signal is input, current flows in the stator 15 of an X-ray tube 11 through a high voltage switching device 14 so that a rotor 5 starts to rotate. When an anode 7 reaches a high speed rotation number and a filament is heated, a radiography radiation signal is output to a radiography operation circuit. When an X-ray radiation signal stops, a stator drive circuit 43 outputs an X-ray tube stator drive signal after a predetermined time in order to maintain the high speed rotation of the rotor 5 of the X-ray tube 11. Thereby, the rotor 5 maintains a required high speed rotation number at a radiography time. After the series of the radiography, a reset signal 55 is output from a timer circuit 44 so that braking is applied to the rotor 5 so as to quickly stop the rotation of the anode 7 of the X-ray tube 11.

Title: Position detecting method
Inventor: HAGIMAE KINUYO
IPC: G01B11/00
Filed: 1986-04-04
Abstract: PURPOSE:To improve the reliability and efficiency of processing by detecting plural straight lines as features of a body to be detected and obtaining position information on the body to be detected from the position relation among those straight lines. CONSTITUTION:Only straight line edges parallel to a (y) axis are detected in an input picture 11, 1 is stored in a binary memory 28 as an edge part and 0 is stored as other parts, and information on them are held. Then, necessary information is extracted from the detected straight line edges and compressed. The detected lines are only lines which are almost parallel to the (y) axis, so linear projection data 13 is obtained, but the compressed data are different because of a fine difference in angle among the straight lines. Then, the rotational correction of the data is made to obtain a feature quantity characteristic to the object as the linear projection data 13. Lastly, matching with model data 14 which is prepared is performed so as to know the position of the object from the linear projection data 13.

The element is molded by dripping with an epoxy resin containing rubber particles. As the material for a rubber particle, all kinds of rubbers such as a copolymer being mainly constituted of polybutadiene or butadiene can be used. The use form can be made in an any form and in the post-molding final form with dispersion of rubber particles in the molding resin.

Title: Overvoltage prevention circuit
Inventor: YUDA TOKUJI
IPC: H02M3/28
Filed: 1987-03-30
Abstract: PURPOSE:To prevent overvoltage safely, by adding a resistance in parallel to the partial pressure resistance to detect output voltage. CONSTITUTION:A overvoltage protection circuit of a switching power unit performs switching of DC current with a switching transistor (Tr) Q on the primary side of a transformer T and feeds the current to the load through diodes D1-D2 on the secondary side, a choke coil L and a smoothing capacitor C. The output voltage is detected with resistances R1 & R2 and a variable resistance VR and fed back to a driver circuit B of a Tr Q through a feedback amplifier A, so that the overvoltage of output is prevented. On this occasion, resistances R3 and R4 are added to connect in parallel to partial pressures R1, R2 and VR. The midpoint of these parallel additional resistances R3 and R4 is connected to a contact P of the variable resistance VR. The condition under which the feedback becomes zero can thereby be prevented, even if the contact P is opened.
