Title: Shape straightening method of metallic strip
Inventor: KAJIWARA TETSUO
IPC: B21D1/05
Filed: 1984-06-13
Abstract: PURPOSE:To improve the productivity and the product accuracy by sticking a strain gauge to the same position of the surface and the rear side of a strip, also providing a slit in the peripheral direction at the corresponding position of a roll, and measuring continuously strains on the surface and the rear side of the strip. CONSTITUTION:A strain gauge 4 is stuck to the same position of the surface and the rear side of a metallic strip 1, respectively. At a position where the strain gauge 4 passes through on the surface of a roll 2 and 3, a slit 21 whose width is wider than the width of the gauge 4 is provided in the peripheral direction of the roll. Also, this slit 21 is buried by a synthetic resin, etc. of a low Young's modulus. By this measuring device, the peak strain of the time when the strip 1 passes through the rolls 2, 3 is derived, and also a radius of curvature is obtained by arithmetic. By using this bending radius of curvature, the shape is straightened based on a relation between plate thickness, tension, roll push-in quantity, etc. which are derived in advance, and the radius of curvature. According to this method, the operation is executed stably, and also the productivity and the product accuracy are improved.

Abstract: PURPOSE:To prevent a paper supply roller from being in contact with a paper supply box by composing the paper supply box freely movable perpendicularly to the axis of the paper supply roller, and putting the paper supply box at a predetermined position without producing distortion of papers. CONSTITUTION:When a paper supply table 15 is moved from the front back, a rotation roller 29 is applied to a protrusion 30 on the side of the paper supply table 15, and an angle formed by a first link 25 and a second link 28 becomes large by motion of the rotation roller 29 along the plane surface of the protrusion 30, so a paper supply box 16 and a paper supply box bearing 23 move along guide rails 19, 20 toward a paper supply roller 13. The paper supply box 16 moves perpendicularly to the axis of the paper supply roller 13. As a result, the paper supply box 16 is contained at a predetermined position without producing distortion of papers, thereby contact of the paper supply roller 13 with the paper supply box 16 can be prevented.

Title: Call connection control method
Inventor: NISHIKADO YUTAKA
Filed: 1988-05-19
Abstract: PURPOSE:To easily and surely identify an outgoing terminal even by the user of a general public communication network by attaching the operating sequence of a call cutoff request and a call connection request between a general terminal housed in the public communication network and a converter. CONSTITUTION:When outgoing is issued from the general terminals NPT1 to NPTm housed in the public communication network 1 to packet terminals PT1 to PTn housed in a packet conversion network 2, the call connection request from the general terminals NPT1 to NPTm is accepted by a PAD3 first, and call connection is completed once. Next, the call connection with the general terminal that is an original connection destination is requested again by the PAD3. When re-connection is completed, the PAD3 transmits a call connection confirmation notice to confirm the general terminal, and when the correctness of the content is confirmed, the general terminal side returns a terminal confirmation response on which the status information of a normal response is set to the PAD3. Thus, when the identification of the general terminals NPT1 to NPTm is completed, the PAD3 requests the call connection with a designated opposite terminal of the packet terminals PT1 to PTn, and when it is completed, a state progresses to an ordinary data transfer state between the terminals.

Title: Apparatus and method for detecting ink run-out for ink-jet recording, and recording medium having ink run-out detection program for ink-jet recording recorded therein
Inventor: IGUSHI NAOKI
IPC: B41J2/125
Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To correctly detect an ink run-out even when ink run-out detection sensors show a large difference of detection outputs. SOLUTION: The apparatus has an ink run-out detection sensor 18 for detecting a concentration of an inspection mark 19 which is formed by blowing ink drops to a recording paper 6. A detected value of the concentration from the ink run-out detection sensor 18 is compared with a preliminarily set threshold value, thereby detecting an ink run-out. In a set mode for the threshold value, the ink run-out detection sensor 18 detects concentrations of a white reference paper set at a concentration indicating an ink run-out state and a black reference paper set at a concentration indicating the presence of ink, and sets the threshold value between concentration detection values of the white reference paper and black reference paper on the basis of the detected values.
