Title: Liquid crystal display device
Inventor: MATSUZAWA KAZUFUMI
IPC: G02F1/1335
Filed: 1988-03-07
Abstract: PURPOSE:To easily and certainly position a light quantity correcting member by providing protruding sections, snap holes, and long holes to the member. CONSTITUTION:In a liquid crystal display device provided with a cold cathode ray tube 3 and light quantity correcting means 1, plural protruding sections 7 are provided to the member 1 and snap holes or long holes are formed at the inside of the protruding section 7. When the protruding sections 7 are formed, grooves 9, in which the protruding sections 7 are put at the time of positioning the member 1, are formed on a reflecting plate 2. Moreover, since the protruding sections 7 are provided at the central part of the member 1 in the longitudinal direction, the positional deviation between a light quantity correcting pattern 8 and the cold cathode ray tube 3 provided at the lower section can be minimized against the longitudinal extension and contraction of the member 1. Therefore, the light quantity correcting member 1 can be positioned easily and certainly at the time of assemblage and, at the same time, the positional deviation of the member 1 caused by the extension and contraction of the member can be prevented.

Title: Damping heat accumulator
IPC: F28D20/00
Filed: 1992-03-12
Abstract: PURPOSE:To regulate a vibrating period corresponding to a building by movably providing a partition plate in parallel with a sidewall of a reservoir substantially in an upstream area of the reservoir. CONSTITUTION:Partition plates 5a, 5b are movably provided substantially in an upper layer area of a reservoir 1. Accordingly, if mass of heat storage water of a part previously partitioned by the plates 5a, 5b are so set as to become a predetermined ratio to that of a building, when vibration occurs at the building by an external force, the water in the reservoir 1 is fluctuated substantially in the same period as that of the building in a predetermined phase difference, thereby buffering the vibration of the building. Since the partitions 5a, 5b are arranged in parallel with sidewalls 2a, 2b of the reservoir 1, a water flow is not disturbed when the water is fed in and out. Further, since they are movably formed, vibrating period of the water can be brought into coincidence with that of the building by regulating the plates 5a, 5b even if the reservoir 1 is unitized.

Title: Ferromagnetic tunnel junction device and fabrication method thereof, and magnetic sensor employing this device
Inventor: SATO MASASHIGE
IPC: H01L43/08
Filed: 1999-03-02
Abstract: PROBLEM TO BE SOLVED: To allow voltage dependency of a resistance value and a resistance changing rate to be reduced or suppressed by including a tunnel junction having a layered structure of a ferromagnetic material/an insulating material/a ferromagnetic material, and providing this tunnel junction and insulating layers with a material having asymmetric voltage-resistance characteristics and composition distribution along a voltage applying direction. SOLUTION: Three insulating material layers 23, 24, 25 having different compositions are layered between ferromagnetic layers 21, 22 to form an insulating layer 26, and a layered structure including the ferromagnetic layer 21/the insulating layer 26/the ferromagnetic layer 22 constitutes a ferromagnetic tunnel junction. The insulating layer 26 does not have a continuous distribution with respect to the concentration of a specific component (e.g. oxygen in an aluminum oxide insulating layer) along an axis indicating a voltage applying direction in the insulating layer (tunnel barrier layer), but has an asymmetric concentration distribution. In addition, through a heat treatment of the insulating layer 26, the step-like shaped concentration distribution curve for the specific component thereof can be changed to be almost continuous.  Thus, a V-R characteristic of the junction device can be also become asymmetric, and the voltage dependency of the resistance values can be mitigated.

Title: Method for attraction and extermination of monochamus alternatus hope in production-promoting stage of pine resin
Inventor: YAMAZAKI TOORU
IPC: A01N43/40
Filed: 1979-05-02
Abstract: PURPOSE: To increase the yield of pine resin, and to exterminate Monochamus alternatus Hope, easily, without environmental pollution, at a low cost, by applying the circumference of the lower part of a pine tree with horizontal notches, and injecting or coating an agent such as "Paraquat"  or "Gramoxone"  to the notch.  
     CONSTITUTION: The yield of pine resin is increased and Monochamus alternatus Hope can be attracted and exterminated by applying horizontal notches to the circumference of the lower part of a pine tree 1, and injecting or coating an agent such as a solution of "Paraquat"  or "Gramoxone"  to the notch. The notch is applied to cut the periphery of the pine tree only pertly every several months, and should not cut all around at a time. By controlling the yield of pine resin, Monochamus alternatus Hope can be effectively exterminated without withering the pine tree. When the pine tree is weakened in the course of the pine resin production, a large amount of pine resin can be obtained by lumbering the tree before withering. The attracted insects are killed by applying an insecticide thereto or adding an insecticide to the solution applied to the tree.

Filed: 1996-03-12
Abstract: PROBLEM TO BE SOLVED: To decrease the generation of sludge by controlling the grain size of normal portland cement and a binder compsn. comprising a specified blast furnace granulated slag. SOLUTION: This binder compsn. is used for centrifugal forming of concrete and is prepared by compounding 95-20wt.% normal portland cement (about 3200 Blaine powder degree) and 5-80wt.% blast furnace granulated slag in which particles having 3500 to 8000 Blaine powder degree and <=5μm particle size are substantially removed. As for the blast furnace granulated slag fine powder, such a slag is preferable used that, for example, a blast furnace granulated slag is pulverized in a vertical roller mill or ball mill to obtain 3500 to 8000 Blaine powder degree and then particles of <=5μm particle size are removed by using a high-performance air classifying machine. In a centrifugal forming process, the compsn. and water is kneaded and put in a die, which is slowly rotated by a die rotating means equipped with driving rollers and driving motors.  Thus, excess water is squeezed out by 30 to 40G centrifugal force to obtain a formed body.
