A coarse position sensor is provided for an optical recording device to generate a substantially linear coarse position signal, indicative of the position of a coarse carriage along the range of its travel, and which also is substantially immune to environmental and device variations. The sensor includes a light source mounted to a drive frame at one end of the range of travel, a position sensitive device fixed to the frame at the opposite end of the range of travel and facing the light source, and a deflecting optical element mounted to the coarse carriage in the path of the light. As the coarse carriage travels along its stroke between the inner and outer diameters of the optical disk, the amount of deflection of the light beam on the position sensitive device from a reference location will change. Based upon a trigonometric equation, a coarse position signal generator receives the output of the position sensitive device and generates a substantially linear coarse position signal indicative of the position of the coarse carriage.

The present invention is a system and method for generating a barcode with a human readable interpretation (HRI). The method involves receiving characters as an input data set that comprises a series of unique data sets each comprising a unique application identifier. For each adjacent pair of data sets, a special character is inserted between the two data sets of the pair. The method further includes generating a barcode encoding data set for encoding the barcode based on the input data set, including interpreting the special character as a separator between data sets; generating a data set for the HRI based on the input data set, including converting the special character to a “_” (space); and generating the barcode with the HRI including combining the barcode encoding data set and the data set for the HRI.

A side wall construction for a continuous belt caster includes a metallic side wall body and a refractory layer attached on the central portion of the side wall body. The metallic side wall body has side edge portion extending substantially in flush with the the surface of the refractory layer. The refractory layer is formed with a center projection of essentially triangular cross-section. The height of the peak of the projection is gradually decreased toward downstream of transfer direction of the liquidus and solidus metal. On the other hand, it may be possible to formulate the refractory layer as double layer construction of a heat insulating refractory layer and a wear-resistantive refractory layer.

A high speed pickling device for causing a thin plate to travel in acid fluid and removing through pickling oxidized scales which are formed on the surfaces of the thin plate, a plurality of weir members which dam wakes of the acid fluid flowing along the surfaces of the thin plate over substantially the entire width of the thin plate are provided in the traveling direction of the thin plate with a predetermined interval and close to the thin plate.The weir members are provided close to the surfaces of the thin plate for damming and stripping off wakes of the acid fluid flowing along the surface of the thin plate at the inlet sides of these weir members, the acid fluid is caused to deflect in the opposite direction away from the thin plate, and fresh acid fluid is sucked onto its surface at the outlet sides of the weir members along with the traveling of the thin plate.According to the present invention indicated above, by providing the weir members close to the thin plate, wakes of the acid fluid which flows along the thin plate is dammed and the most part thereof is stripped off from the thin plate. This stripped acid fluid flows in an opposite direction away from the thin plate and is drained along the weir members. The remaining wakes which were not stripped off by the weir members pass through a narrow clearance between the thin plate and the weir members and proceeds to the outlet sides of the weir members in the form of thin layered wakes. At the outlet sides of the weir members thickness of the wakes along the thin plate again tends to increase and fresh acid fluid is sucked to increase the wake thickness. By these draining and sucking of the acid fluid, replacement of the acid fluid is surely performed and pickling effect is enhanced and the pickling time is shortened.

A plate-like rolled material fed from a continuous casting equipment is rolled by a vertical mill for width control. A pair of horizontal mills are disposed one on each of the entry side and the delivery side of the vertical mill. Both the horizontal mills are controlled in their speeds to impart a predetermined tensile force to the rolled material without effecting thickness control of the rolled material. The roll speed of the horizontal mill disposed on the delivery side is controlled to be higher than that of the horizontal mill disposed on the entry side. This enables preventing of failure in the shape of the rolled material.
