Title: Magnetic recording/reproducing device
Inventor: KORI TOSHIYUKI
IPC: G11B5/027
Filed: 1988-03-16
Abstract: PURPOSE:To attain the satisfactory editing jobs at each joint even with such a tape that has the track curves by switching a 1st magnetic head to a 2nd magnetic head to record the information signals. CONSTITUTION:The curves of the recorded tracks are detected and stored as tracking error signals earlier than the scans of the 1st magnetic heads 3 and 4 by a prescribed time. Then an arithmetic operation is performed so that the tracking error data is gradually converged to zero for each track. The tracking error signal calculated at recording is supplied to a drive circuit 16 for electricity-machine converting elements 1 and 2 respectively. Thus the positions of both heads 3 and 4 are controlled and the joint number track is recorded at the editing initiation. Hereafter the recording track is switched to the 2nd magnetic heads 5 and 6 for recording jobs. Thus no big difference is produced between the track curve for recording the new video signals and the recorded track curve. Then the adverse influence can be avoided to the recorded tracks at the inserting editing start and stop points.

Abstract: PROBLEM TO BE SOLVED: To prevent generation of contact failure after surface mounting due to the difference in thermal expansion between a semiconductor chip and a board, by providing one end of each of metal thin wires of a predetermined length on each pad of the semiconductor chip by wire bonding, and mounting the other end of these metal thin wires on the board. SOLUTION: A ball portion 23a is bonded onto a pad portion of a semiconductor chip 21 using a wire bonding technique, and a wire 23b is lifted up. When a predetermined length is reached, the wire 23b is cut by a cutter or fused by a torch, and a bonding wire 23 is bonded onto all the pad parts of the semiconductor chip 21.

Title: Energization transfer printer
Inventor: TAKEI TORU
IPC: B41J2/325
Filed: 1988-03-18
Abstract: PURPOSE:To improve the form of recording dots and thereby obtain high-quality print by allowing the tips of electrodes to have a fixed gradient with the center line of an electrode in the same direction. CONSTITUTION:The tips of opposed electrodes 1 are allowed to have a gradient with the center line of an electrode in the same direction. In order to permit growth of dots which incline to neither a scan direction nor a subscan direction, the gradients theta1, theta2 should be 45 deg.. However, the gradient can be steep or gentle, depending upon recording conditions. In short, the gradient should be provided in the same direction. The ideal gradients are 30 deg., 45 deg. and 60 deg. from the viewpoint of the mesh angle of a mask used for the formation of electrodes using thick film paste, or abrasion-resistant tungsten, molybdenum, nickel, etc., by means of plating or sputtering. Because of all the tips of the opposed electrodes 1 having a gradient in the same direction, the dot form obtained has an intermediate density in which adjoining dots are not connected to each other and incline to neither a scan direction nor a subscan direction. Consequently, this is effective for improvement of the image quality.
