Title: Production of magnetic recording medium
Inventor: YAGI TAKAYUKI
IPC: C23C14/24
Filed: 1985-06-06
Abstract: PURPOSE:To reduce the variations of the composition of the titled medium and to improve the magnetic characteristic and productivity by carrying out vapor deposition while continuously supplying an alloy consisting essentially of Co and Cr to be deposited into the melt of the vapor deposition substance. CONSTITUTION:The rod-shaped substance 31 of an alloy consisting essentially of Co and Cr is supplied from the upper part of a guide 33 into a heat-resistant crucible 34 by a roll 32 rotated by a motor and heated by an electron beam 35 and melted. The center of the heat-resistant crucible 34 is positioned directly below the center of a can 13. The incident angles in the initial and the final stage of film formation are controlled by a shielding plate 43, the supply rate of the alloy 31 is controlled by atomic absorption film thickness monitors 41 and 42 capable of independently measuring the evaporation rate of Co and Cr so that the ratio in the evaporation rate of Co to Cr is made constant and the current of the electron beam 35 is controlled so that the evaporation rate of Co or Cr is made constant. Consequently, a Co-Cr magnetic recording medium having uniform film thickness and composition is continuously formed on a base film.

IPC: G11B20/14
Filed: 1989-05-16
Abstract: PURPOSE:To prevent the display time of a reproducing image from being remarkably fluctuated in specific reproduction where track jump is performed by controlling the cycle of in-frame encoding corresponding to the recording position of a disk of constant linear velocity system. CONSTITUTION:The in-frame encoding is performed at the recording position at the innermost peripheral side of the disk setting, for example, continuous seven frames in point of time as the cycle, and remaining six frames receive the processing of inter-frame framing. As a result, encoded data is which encoded data F1 corresponding to the image data of a first frame generated in the in-frame encoding is located at the three frame periods in the periods of seven frames, and encoded data F2-F7 corresponding to the image data of second- seventh frames are generated at the periods of remaining four frames are generated. Those seven frames are varied at the recording position in the radius direction of the disk. In the control of the cycle, the cycle of the outer peripheral side of the disk is set longer than that of the inner peripheral side. In such a way, it is possible to prevent the display time of the reproducing image from being remarkably fluctuated by the reproducing position in specific image pickup.

Title: Hard al alloy sheet for packing having superior curlability and production thereof
Inventor: KANEDA YUTAKA
IPC: C22C21/06
Filed: 1987-05-19
Abstract: PURPOSE:To enable uniform and smooth curling and seaming as well as to increase the strength and to reduce the thickness by adding specified amts. of Mg and Mn to Al and regulating treatment conditions in a producing stage so as to restrict the strength anisotropy of the resulting sheet to a specified value or below. CONSTITUTION:An Al alloy ingot consisting of, by weight, 3.5-5.5% Mg, 0.3-0.7% Mn and the balance Al is homogenized at 450-550 deg.C, hot rolled, cold rolled, process-annealed and cold rolled at 45-75% draft under conditions which regulate the temp. of the resulting sheet immediately after the rolling to <=120 deg.C. By this method, the strength anisotropy of the sheet is restricted to <=1.5kgf/mm<2>. In the case of <3.5% Mg content, satisfactory strength is not obtd. In the case of >5.5% Mg content, the strength is excessively increased and the formability is deteriorated. In case of <0.3% Mn content, the strength increasing effect is hardly produced. In the case of >0.7% Mn content, the strength is excessively increased, the formability is deteriorated and macro- crystals are formed to cause trouble during working. In case of >1.5kgf/mm<2> strength anisotropy, defective curling and seaming is liable to be caused.

Abstract: PURPOSE:To reduce the branch loss of light by forming an incomplete fusion part as a light branching layer in the front end of the join part of branch paths. CONSTITUTION:A clad 3 having a Y-shaped groove where an angle 5 of branch paths 2a and 2b is fixed is formed with an injection molding machine 7 and a mold 8. A polymethyl methacrylate is charged from the upper part of the Y shape, namely, from the side of branch paths 2a and 2b simultaneously to form a core by injection molding, and a weld line 6 due to join between two kinds of resin is formed in the front end of the join part of the core part of this obtained optical circuit board. The light made incident from the side of a main optical path 1 of the optical circuit board is branched by the weld line 6 as the incomplete fusion layer and is divisionally propagated to branch paths 2a and 2b. The part where the incomplete fusion layer 6 is formed corresponds to branch paths having a considerably small branch angle. Thus, the branch loss of light is reduced very much.

Filed: 1985-06-07
Abstract: PURPOSE:To obtain an electrically conductive resin exhibiting high electrical conductivity even at a low content of electrically conductive filler, by adding an electrically conductive oxide filler in combination with a charge transfer complex to a resin. CONSTITUTION:(A) An electrically conductive oxide filler, preferably zinc oxide doped with Al or titanium oxide having Sb-doped SnO2 coating layer and (B) a charge transfer complex, preferably a complex containing boron and nitrogen are kneaded into a resin under heating or at normal temperature using twin roll or three-roll mill or with an injection molding machine. The component B is attached preferably to the component A prior to kneading. By the addition of the component A and component B in combination to the resin, the component A is surrounded with the component B, and accordingly, the electron movement in the component B near the component A is induced by passing electric current through the component A to cause the electron flow of A B A. Consequently, high electrical conductivity can be imparted to a resin by the addition of only a small amount of the component A.
