Title: Compound magnetic reluctance head
Inventor: NEIRU SUMISU
IPC: G11B5/48
Filed: 1994-11-30
Abstract: PURPOSE: To improve the reproduction of the digital data having a short wavelength and an extremely narrow track width by constituting the magnetic head with three-dimensional characteristics. CONSTITUTION: The parts 42 and 46 of an MR element 38 and the parts 40 and 44 of the MR element 36 are the area of this duplex magnetic resistance head(DMR) to be connected to the MR elements and a detection current lead is omitted and shown in Figure. When a bias magnetic field in a longitudinal direction is applied in the same direction as the elements 36 and 38 in the areas 42, 46, 40 and 44, magnetization 48, 50, 52 and 54 provided with mutually, parallel longitudinal direction components is generated. For the lead to the MR element 38, since a resistance value is smaller than the MR elements themselves and the large part of a current is made to flow to the areas 42, 46, 40 and 44, mutual horizontal direction bias is hardly present in the areas and the direction of the magnetization is held almost in the longitudinal direction.  However, in an action area at the center of the elements 36 and 38, the unidirectional rotation of magnetism 56 in the area 32 is generated for mutual bias action and almost the same amount of rotation is generated in the opposite direction of the magnetization 58 in the area 32.

Title: Magnetic recording medium
Inventor: URABAYASHI MASAAKI
IPC: G11B5/706
Filed: 1987-11-25
Abstract: PURPOSE:To obtain a magnetic recording medium which is capable of recording video signals and sound signals with good sepn. by dividing a magnetic recording layer to >=2 layers by a layer consisting of a Class 2 high-temp. superconductor or layer contg. the Class 2 high-temp. superconductor. CONSTITUTION:The magnetic layer is divided to two layer by a thin film 3 of the Class 2 high-temp. superconductor formed by a vacuum film forming technique such as sputtering method. The video signals which are higher in frequency are recorded on the front side of the magnetic layer and the sound signals which are lower in frequency are recorded on the deep side of the magnetic layer in the case of recording the video signals and the sound signals in sepn. with a VTR. While the sound signals which are low in frequency can be recorded deep in the recording medium 1 since the magnetic resistance of the Class 2 high-temp. superconductor is small, the video signals are high in frequency and, therefore, the magnetic resistance of the Class 2 high-temp. superconductor is so high that the video signals cannot pass the Class 2 high- temp. superconductor 3. The magnetic recording medium which is high in the degree of sepn. of respective frequency bands is obtd.

Title: Manufacture of reflecting mirror with mutilayered membrane
Inventor: MURAKAMI KATSUHIKO
IPC: G02B5/08
Filed: 1988-11-28
Abstract: PURPOSE:To enable keeping a high reflectivity at whole reflecting curved surface by varying the frequency in varying thickness of membrane of a multi-layered membrane formed on a curved surface, by a heating process, in the manner of satisfying Bragg's refraction condition at every place. CONSTITUTION:On a curved surface made of a base material 1, a material 2 such as a tungsten which has a reflection index differing greatly from that of a vacuum, and another material 3 such as a carbon which has a reflection index differing slightly from that of a vacuum, are alternatively laminated, and the frequency of varying thickness of membrane laminated on the material 2 and the material 3 is controlled (in this case, at a place the closer to a sectional center, the membrane becomes thicker, and at a place the closer to a sectional edge, the membrane becomes thinner) so as to satisfy Bragg's refraction condition at every place of the curved surface, by heating processes applying different temperature at each place. At this processing, a crystallization condition of the multi-layered membrane varies in accordance with a varying condition of a thickness distribution, in other words, under the higher temperature the membrane is processed, the more micro-crystallization progresses. Also, by applying a heating process, with the increase of the variation frequency in the membrane thickness, the reflectivity of the materials increases and consequently those effects contribute to the improvement of an effectiveness of the reflecting mirror.

Title: Dynamic value sensor
Inventor: KURATA NOBUO
IPC: G01P15/12
Filed: 1990-11-02
Abstract: PURPOSE:To enable the ensuring of a high measuring accuracy by setting an upper space within a container filled with no damping oil to a specified pressure lower than an atmospheric pressure to prevent changes in internal pressure attributed to a temperature change. CONSTITUTION:A container 1 is filled with, for example, a damping oil comprising a silicon oil 10 at a rate of about 80% of the capacity of the container 1 to an extent that a dynamic value detector 8 and a partition wall 6 are immersed so as to let the element 8 have a damper effect for acceleration while an area filled with no damping oil 10 above the partition wall within the container 1 is made to be a vacuum space 11 as such with a specified pressure lower than an atmospheric pressure. The space 11 has neither expansion nor contraction in volume attribute to a temperature change and a volumetric change, if any, if absorbed by the space 11 even when caused in the damping oil 10 by a temperature change. This eliminates effect on the element 8 by a pressure change attributed to the temperature change to check a drop in measuring accuracy attributed to the temperature change thereby ensuring a high measuring accuracy.

Title: Picture processor
Inventor: KANEDA YOSHIO
IPC: G06T1/00
Filed: 1987-11-25
Abstract: PURPOSE:To obtain an optimum picture for measurement in a short period by processing, in the first place, a picture signal obtained from a non-interlace, shifting an object or a video camera until a prescribed picture is obtained, and switching the scanning system to a 2:1 interlace after the prescribed picture is obtained. CONSTITUTION:The scanning system of a video camera 2 is set at the non- interlace, the picture signal is taken in through an A/D converter 5, and the focal coincidence evaluation factor such as the rate of change of a light-and- shade contrast is calculated by picture data. After the storing of a value, a motor 4 is sent by a constant quantity, and a microscope 1 or the video camera 2 is approximated to the object. After its stopping, the picture signal is fetched, and the same processing is carried out. By repeating the processing, the focal coincidence evaluation factor gradually rises, its peak is obtained at a position where an optimum focus is obtained, and thereafter, it falls. The peak position is obtained at a time point when a few steps have passed farther than the peak, and the motor 4 is reversely rotated, and the scanning system is switched to the 2:1 interlace. Thus, automatic focusing can be carried out in a short period.
