The present disclosure relates to a hot rolling apparatus for manufacturing a metal plate by hot-rolling-treating a metal material including copper. The apparatus includes: a rough rolling device for rolling-treating the metal material, which has been heating-treated, a plurality of times with a back-and-forth movement of the metal material, to mold the metal material into a metal plate; a heat retention/application treatment device for retaining heat of or applying heat to the metal plate molded by the rough rolling device at lower temperatures than in the heating treatment, without applying bending; a finish rolling device for further rolling-treating the metal plate that has been heat-treated by the heat retention/application treatment device; a cooling device for cooling the metal plate that has been rolling-treated by the finish rolling device; and a support table for movably supporting the metal plate from below before and after the rough rolling device while the metal material is moved back and forth by the rough rolling device. According to the present disclosure, it is possible to improve the quality of the metal plate manufactured in the hot rolling apparatus, and also to improve the speed of the process required for rolling.

A shape detecting apparatus for controlling the tension of a rolled plate, is composed of a pair of fixing members, a supporting frame and a plurality of shape detecting units. The shape detecting units are fixed detachably in a close proximity of the supporting frame in the lateral direction. The shape detecting units are each composed of cylindrical divided rolls in contact with the rolled plate, a fixed member fixed on the supporting frame, an arm member of which one end supports the divided roll rotatably, and of which the other end is fixed on the fixed member, and a load detector for detecting a moment of rotation acting on the arm member.

According to one embodiment of the invention, an electronic device comprises a speaker, a microphone, and a processor that executes pairing process with another electronic device, the processor outputs pairing signal during pairing process. The electronic device further comprises a converter coupled to the speaker, the microphone, and the processor. The converter converts the pairing signal to an audio signal when the speaker outputs audio signal to another electronic device, and converts an audio signal to pairing signal when the microphone receives the audio signal. Also, the electronic device includes a wireless communication module coupled to the processor, and the wireless communication module communicates with another electronic device after pairing process.

This invention relates to an individual-identifying apparatus in which a plurality of output electrodes are arranged at regular intervals in a direction perpendicular to a longitudinal direction of a finger, a single input electrode is arranged at an end along the direction in which the output electrodes are arranged, the output of an oscillator which outputs a signal of a predetermined frequency is sequentially supplied to the output electrodes via an analog switch group, an electric signal output from the input electrode is detected by a phase detecting circuit, and the output of the circuit is converted to a digital signal by an A/D converter, thereby detecting the irregularity pattern of the finger to identify an individual. This individual-identifying apparatus can perform stable individual identification which is not easily influenced by the surface state of the finger, for example, whether or not it is damp, or by outside noise.

A specific color field recognition apparatus and method are disclosed. A mechanism fetches a first image including a specific color and a second image with the specific color eliminated therefrom by picking up an image of an object having a specific color field to be recognized. A device produces a first density histogram and a second density histogram representing the number of pixels for each tone with respect to the first image and the second image, respectively. A converter determines a plurality of local maxima in the first and second images and converts the density of the first and second images in such a manner at the first image a background portion which is lowest density of the local maxima represents minimum of the gradation field, label portion which is highest density of the local maxima represents maximum of the gradation area, at the second image the background portion density represents lowest density of the gradation field, the letter density which is maximum of the local maxima represents a value which is inverted highest pixels of the local maxima of the first image.
摘要:
An apparatus for changing the rolls of a vertical rolling mill stand by moving each roll of a roll pair to the roll changing position transversely outwardly of the rolling position where the spacing between the rolls is maximum and then pulling upwardly the roll together with its upper and lower bearing boxes from a housing. The rolls may be changed even when a slab is passing.
