Title: Production of master disk for optical recording medium
Inventor: SAKATA REIKO
IPC: G11B7/26
Filed: 1986-11-13
Abstract: PURPOSE:To easily obtain a master disk with which uniform tracking signals are obtainable by changing the baking temp. after coating of a photoresist in a method for forming address pits by laminating and forming resist layers having different sensitivities successively on a substrate, then exposing and developing said layers according to the sensitivity of the respective layers. CONSTITUTION:After the 1st photoresist layer is coated to the thickness corresponding to 1/8 reading wavelength lambda on the substrate, the resist layer is baked at >=120 deg.C, by which the 1st resist layer 3 having the low sensitivity is obtd. The 2nd photoresist layer is then coated thereon and is baked at <120 deg.C by which the 2nd resist layer 4 having the sensitivity higher than the sensitivity of the 1st resist layer 3 is obtd. Two layers of such resist layers 3, 4 are exposed by using laser light to sensitize only the high-sensitivity layer 4 and laser light to sensitize both the layers 3, 4 and is developed. The master disk which have lambda/4 and lambda/8 depths of the address pits and guide grooves and are rectangular in the shapes of both the pits and grooves is thereby obtd. Since the depth of the guide grooves is less sensitive to the exposure, the thickness of the 2nd resist layer 4 is easily uniformed. The uniform tracking signals are thereby obtd.

Abstract: PURPOSE:To precisely confirm the discrimination of the performance of an overcoat by applying an undercoat as the primary lining with a low-viscosity liq. resin of a specified color and forming a secondary lining on the undercoat with a high-viscosity liq. resin of a different color. CONSTITUTION:The inner face of a pipeline in the repairing route is lined with resin twice in succession. In the first stage, a low-viscosity resin of about 5000CPU is injected into the pipe in the repairing route from an automatic resin mixing injector 53 through a repairing jig 5, pushed by a low-pressure high-speed air current from a blower 52 and sent into a horizontal branch pipe 2 to form a coating film of desired thickness by the adhesion to the wall surface. The resin is colored white, for example. In the second stage, a high- viscosity resin of about 10,000CPS is injected into the pipe in the repairing route in the same way as before to form a specified coating film. The resin is colored red, for example, unlike the low-viscosity resin.

Title: Spin-dependent switching element
Inventor: NAKAJIMA KENTARO
IPC: G11C11/16
Filed: 1999-09-22
Abstract: PROBLEM TO BE SOLVED: To provide a spin-dependent switching element suitable for embodying a magnetic memory device having a high level of integration and low electric power consumption in combination. SOLUTION: This element has the constitution obtained by arranging a source 11, drain 12 and gate electrode 13 consisting of ferromagnetic materials to a charge island 10 having a very small size in such a manner that these respectively form tunnel junctions. A spin-dependent chemical potential shift is generated in the charge island 10 by a spin accumulation effect when the magnetization array of the gate 13 and the drain electrode 12 is autiparellel. The tunnel conductance between the source and the drain is changed dependently upon the magnetization array of the electrodes by the chemical potential shift. When the element is applied to a magnetic memory cell which uses the magnetization array of the electrodes as recording information, reading-out output may be taken larger than in the prior art using a ferromagnetic tunnel effect.  Since the element itself has a switching function, the need for transistors for cell section is eliminated and the element is suitable for the higher level of integration of the cells.
