Title: Magnetoresistive device and magnetoresistive memory device
Inventor: IKEDA TAKASHI
IPC: H01L27/105
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To enable a magnetoresistive device to operate with a small magnetic field by setting the coercive force of a magnetic layer which has a coercive force larger than the saturation magnetic field of another magnetic layer possessed of a small coercive force, and making the former magnetic layer consist mainly of gadolinium and transition metal. SOLUTION: The multilayered film of a magnetoresistive device is composed of a substrate 10, a first ferromagnetic layer 21, a non-magnetic layer 22, a second ferromagnetic layer 23, and a protective layer 24. Within the range of an applied external magnetic field, the magnetic layers 21 and 23 are magnetized in parallel or anti- parallel. Magnetic anisotropy is easily induced in the direction of a normal of the surface of a layer in a magnetic layer whose main components are gadolinium and transition metal without using an expansive single crystal substrate or the like or making the magnetic layer undergo a thermal treatment. Furthermore, metals such as Fe, Co, and Ni whose magnetoresistive change rate is large are used as transition metals.  Therefore, a magnetoresistive device is magnetically anisotropic in the direction of a normal on the surface of a film, possessed of a small coercive force, and kept stable in the direction of magnetization even if it is micronized in size.

Title: Dye fixing element
Inventor: AONO TOSHIAKI
IPC: G03C8/40
Filed: 1987-05-06
Abstract: PURPOSE:To prevent curling and to enhance conveyability at the time of heating development and transfer by disposing >=1 layers of back layers contg. hydrophilic colloid to the rear face of a base provided with a dye fixed layer and incorporating specific polymer particles into at least one back layer. CONSTITUTION:>=1 Layers of the dye fixed layers contg. a mordant are provided to one side on the base and >=1 layers of the back layers contg. the hydrophilic colloid are disposed on the opposite side. Polymer particles having the glass transition point ranging 20-160 deg.C are incorporated into at least one back layer. A base or base precursor is incorporated into the dye fixed layers or the adjacent layers thereof and a transparent film is preferably used for the base. Curling of the dye fixing element is thereby prevented. For example, the curling to the dye fixed layer side on an OHP is suppressed and the conveyance is smoothed; particularly, the folding of the front end during a heating treatment is prevented. The effect of preventing the curling is further enhanced by making combination use of colloidal silica for the above-mentioned polymer latex.

Abstract: PURPOSE:To enable the quality judgement of the active layer around a light emitting diode section in the step of manufacturing the wafer, by forming the testing light-emitting diode sections on a wafer, and by applying test voltage to the sections to judge whether or not light is emitted. CONSTITUTION:After a multi-layer grown layer 7 is formed on a wafer 1, the grown layer 7 is mesa-etched to form an optical waveguide path. At the same time when the waveguide is formed, testing light-emitting diode sections 14 are formed on positions representing respective regions of the wafer. When electrodes are formed layer, anode and cathode electrodes 19, 20 of the diode sections 14 are formed, and predetermined voltage is applied between the electrodes 19, 20 to test whether or not light is emitted. As a result of the testing, the wafer is estimated to be a good one when light is emitted. In this way, the wafer can be judged in itself before the wafer is made into a chip.

On the other hand, a q-phase voltage command Vq* is so computed that the d-phase voltage command Vd is multiplied by the delay σ and the speed ω and the resultant product is added to the q-phase voltage command Vq.

Abstract: PURPOSE:To improve memory and orientation characteristics by increasing the anchoring strength of a rubbing direction to the strength higher than the anchoring strength in the direction perpendicular to oriented films. CONSTITUTION:The anchoring strength of the rubbing direction is increased to the strength higher than the anchoring strength in the direction perpendicular to the oriented films 3, 5.

This third stable state is the stable state in the rubbing direction. The force to fix the bearings of the liquid crystal molecules in the rubbing direction is increased in this way, by which the memory characteristic in this direction is improved. The memory characteristic in the other orientation direction is maintained by impressing a DC electric field.
