    摘要: In a tandem rolling mill consisting of at least a first rolling stand and a second rolling stand, the interstand tension is controlled by the steps of detecting the rolling force P.sub.10 and rolling torque G.sub.10 at the first rolling stand after a workpiece is fed into the nip between the rolls of the first rolling stand but before the workpiece is fed into the nip between the rolls of the second rolling stand, storing in a memory the ratio G.sub.10 /P.sub.10 representative of the reference torque arm value for the first rolling stand in a tension-free state, detecting the rolling forces P.sub.1B, P.sub.2B and rolling torques G.sub.1B, G.sub.2B at the respective rolling stands immediately after the workpiece is fed into the nip between the rolls of the second rolling stand, computing the reference torque arm value G.sub.20 /P.sub.20 for the second rolling stand in a tension-free state on the basis of these detected values, and controlling the rolling speed of the first or second rolling stand so that (G.sub.10 /P.sub.10) - (G.sub.1 /P.sub.1) representing the deviation of the torque arm value detected at the first rolling stand in rolling operation from the reference torque arm value G.sub.10 /P.sub.10 stored in the memory is equal to (G.sub.20 /P.sub.20) - (G.sub.2 /P.sub.2) representing the deviation of the torque arm value detected at the second rolling stand in rolling operation from the reference torque arm value G.sub.20 /P.sub.20, whereby the workpiece can be rolled tension-free.

    摘要: The invention provides a power transmission apparatus having a reduced power transmission loss. In the power transmission apparatus, an input shaft side variable pitch circle gear, an output shaft side variable pitch circle gear and a cycloid sliding gear which have a shape accumulated by a cycloid gear in which a pitch circle continuously changes are meshed with each other. The cycloid sliding gear slides and an engagement position thereof changes, thereby changing a radius of an engagement pitch circle of the gear so as to change a shift ratio.

    摘要: An input/output device has a processor which processes data strings received by the device. When a data string is received, it is passed to a serial interface and a timing means. The serial interface generates a signal which interrupts the existing processing by the processor and causes the process to start processing of the newly received data string. At the same time the timing means measures the length of the data string and compares it with a predetermined length set by user-controllable data setting means. If the data string length reaches the predetermined length, the processor is triggered to stop processing the new data string and to recommence the processing it was performing prior to interruption. The unprocessed part of the new data string is stored in a memory.In this way, urgent data strings, which are generally short, are processed rapidly and longer data strings are processed after the urgent data strings. It is not necessary for the data string to contain any information to identify its length.

    摘要: A pattern recognizing device is disclosed, in which the pattern recognition is effected by classifying all the parts of a stroke of an inputted pattern into three groups, those which are clearly arcs, those being clearly segments of line and those which are ambiguous, for which it is not possible to determine whether they are arcs or segments of line; forming a plurality of patterns of stroke structure, each of which is represented by data of a series of elements, which are arcs or segments of line, i.e. by a pattern consisting of those elements for each of the cases where it is supposed that each of the ambiguous parts is an arc or a segment of line, without interpreting it to be an arc or a segment of line; comparing each of the patterns of stroke structure thus obtained with a pluarlity of thesaurus patterns of stroke structure previously registered in a memory; checking the similarity of the structure or the similarity of every smoothly curved or straight part; and selecting a registered pattern having the greatest similarity.
