Title: Printing wire for impact printer
Inventor: IIKAWA TSUTOMU
IPC: B41J2/25
Filed: 1986-07-07
Abstract: PURPOSE:To make a printing head resistant to abrasion, light in weight and low in cost, by using an aluminum alloy wire whereon an oxide film is formed. CONSTITUTION:In a printing head forming a character of dot matrix, an aluminum alloy wire whereon a hard anodized film is put is used as a wire for printing dots. Since the aluminum alloy is light in weight, it reduces a load on an electromagnetic driving system driving a printing wire, and also it is advantageous for high-speed printing. Moreover, the anodized film of the aluminum alloy has high hardness and abrasion resistance. Therefore the wear of the wire can be reduced, and thus the stability and reliability of the operation of the printing head can be secured.

Title: Plate speed predicting method in rolling
Inventor: KITAHAMA MASANORI
IPC: B21B37/00
Filed: 1998-06-08
Abstract: PROBLEM TO BE SOLVED: To precisely plate a plate speed at an outlet side of a rolling mill by calculating a flatted roll radius and a forwarding rate assuming as a roll flatted shape in a circular arc at a rolling time and correcting the forwarding rate based on a roll flatted ratio. SOLUTION: By using place thickness set values at inlet/outlet sides of a rolling mill, tension set values of the inlet/outlet sides, set values of deforming resistance and a friction coefficient, a roll diameter, Young modulus, a flatted roll radius and a forwarding rate are calculated based on a rolling theory in which a roll flatted shape is made of a circular arc at a rolling time. Then, the forwarding rate is corrected based on a roll flatted ratio=flatted roll radius/ roll radius. A forwarding rate ratio is (forwarding rate calculated by taking non-circular arc deformation into account)/(forwarding rate calculated by a conventional model). A relation between the roll flatted rate ratio and the forwarding rate ratio is linear and its variance is small.  By obtaining the forwarding rate ratio from the roll flatted ratio and multiplying the forwarding rate ratio to the forwarding rate calculated by the conventional model, the forwarding rate used for plate speed prediction is obtained.

Abstract: PURPOSE:To accurately input a guard band noise in a vertical blanking period, by stopping a motor with a prescribed timing based on the reproducing output of a control signal recorded at a position corresponding to a video track recorded on a tape in a decelerating state. CONSTITUTION:A CTL signal is recorded on the tape at every interval regulated by the specification of the tape. The CTL signal is recorded in the neighborhood of the tip of the video track at every frame. Therefore, a certain period starting from the reproduction of the CTL signal by heads 7 and 8, is overlapped with the vertical blanking period of the video signal. Accordingly, the position separating by a prescribed distance regulated by the machine style of a VTR, or the specification of the tape from the reproducing position of the CTL signal, forms the guard band, and also, the position corresponds with the vertical blanking period. In this way, by tracing the position by the heads 7 and 8, the guard band noise can be inputted in the vertical blanking period.
