摘要:
A mechanical punching device for punching the tuyeres of a converter properly independently of the angle of inclination of the converter. Link mechanisms, each having two turning arms, are provided on both sides of a carriage with the two turning arms being connected together by the end shaft of the link drive device. The end shaft is a link drive device movable vertically so that the distance between one of the supporting shafts which serves as a fulcrum and one of the holding shafts of the mechanical puncher on the side of the punching rod is shorter than the distance between the other supporting shaft and the other holding shaft. The holding shafts slide along guide slots formed in the side wall of the carriage. The angle of inclination and horizontal and vertical positions of the mechanical puncher are thereby changed with a single operation of the link drive device.

A mechanical punching apparatus for punching tuyeres in which the position of punching rods is varied in a one action in correspondence to movement of the tuyere and in which the mechanical puncher, a carriage and a puncher tilting device are readily accessible for overhaul and maintenance. A mechanical puncher including punching rods assemblies is mounted on a carriage which moves on rails along the longitudinal direction of a converter. A link structure is arranged between the puncher and the carriage for tilting and moving the puncher with the movement being restricted along a predetermined locus having a center at the center of rotation of the converter. The link includes first and second sets of levers disposed between the carriage and puncher with a coupling rod pivotally coupled between levers.

Method and apparatus for punching the tuyeres of a converter with a mechanical puncher mounted upon a carriage running on rails. Light intercepting plates encoded by light transmission holes are disposed opposite each tuyere. Light is shone towards the light intercepting plates and detected on the opposite side thereof by photoelectric elements the outputs of which are coupled to a digital processor which controls the speed and position of the carriage. The mechanical puncher has two cylinders each of which drives two punching rods to successively punch the tuyeres. If it is impossible to punch a tuyere with the mechanical puncher were moving in one direction, the position of the puncher is shifted by one tuyere to start the punching again in the opposite direction.

The present invention provides a recording and reproducing apparatus that can perform high-precision tracking servo control by removing noise from detected servo signals. The recording and reproducing apparatus performs tracking servo control while reading servo signals 10 that are formed on a surface 9 of a recording medium 2 so as to produce optical contrast, the apparatus including a modulated irradiator 20 for irradiating the servo signals 10 with a light beam, the intensity of the light beam being modulated by a modulating wave that is frequency-modulated; a photoelectric converter 30 for converting reflected light from the servo signals 10 into electric signals; and a synchronous demodulator 15 for subjecting the electrical signal to synchronous demodulation using the modulating wave as a reference wave.

A solidified residual iron within a blast furnace is suspended up by employing a shell suspending device fixed to a tuyere arranged in a lower end portion of an upper portion of a furnace body suspended by a lift jack and a solidified residual iron suspending band, thereafter is descended by employing the lift jack and is mounted on a horizontally moving table. Subsequently, the horizontally moving table mounting the solidified residual iron thereon is moved onto a furnace outer truck rail from a furnace inner truck rail so as to be taken out of the furnace by operating a center hole jack arranged near the furnace outer truck rail, whereby an operation of taking out the solidified residual iron within the blast furnace out of the furnace is economically performed for a short time.

An elevator system includes a scanner installed in a call registerer of an elevator hall and/or on a jamb of an elevator hall for scanning the elevator hall or an area proximate the elevator hall; an image recognizing section for recognizing an image captured by the scanner unit; and operation mode selecting unit for switching an operation mode of the elevator based on recognition information supplied by the image recognizing section.
摘要:
A functional material which fades in color with the volatilization of volatile agents such as fragrant agents, deodorant agents, antibacterial agents, etc. so that a user can visually check the end of the effect of such agents. A volatile agent and an oil-soluble dye having a dissolving proportion of 0.0001-1% are carried on a porous carrier undyeable with, i.e. low in affinity for the oil-soluble dye. The content of the oil-soluble dye is 0.1-100 .mu.g per square centimeter of the effective surface area of the porous carrier.

An improvement is provided in sublimable agricultural chemical compositions in the form of rough grains, pulverized powders or tablets which comprises at least one agricultural chemical and a carrier therefor. The improvement resides in the employment as the carrier, triisopropyl-s-trioxane or tritertiary-butyl-s-trioxane.
摘要:
A data recording apparatus of the present invention includes a head that records data signals by magnetizing a magnetic tape 10 and a recording control portion that controls the recording operation by causing recording current to flow to the head. The recording control portion controls the operation of the head, so that in the magnetic tape 10, which is direct current demagnetized continuously in the longitudinal direction, a magnetic field is formed intermittently in an opposite direction to the magnetization direction of the direct current demagnetization. Thus, when recording data signals on the magnetic recording medium, it is possible to make the current flowing to the head small and to realize apparatus power consumption reductions, load reductions for the head and circuitry, and reduction in crosstalk noise from the head chip used for writing to the head chip used for reading.
