IPC: E03B3/36
Filed: 1990-11-26
Abstract: PURPOSE:To enable pumping up to a position in a level higher than a water surface by a method wherein, during a low air temperature except daytime, water and air are introduced in a pressure vessel, air in the vessel is warmed and expanded along with the increase of an air temperature during a daytime to pressurize the water surface in the vessel. CONSTITUTION:A pumping-up device 4 comprises a pressure vessel 11 and storage water tanks 12 and 13, and the pressure vessel 11 comprises a water tank 21 and a roof 22. The roof 22 is made of aluminum capable of sufficiently absorbing a solar heat during a daytime. The roof is formed in an arcuate shape and coated in a black color and of a closure type where the upper part of the water tank 21 is covered. An openable air holes 25 and 26 are formed in a top part and a side part. First, during a low air temperature except the daytime, air is discharged through the air hole 25 of the roof 22 to the outside, and simultaneously, cooled air at the outside is introduced through the air hole 26 to close the air holes 25 and 26. At high tide except a daytime, seat water W is stored up to the level of a sea surface at high tide. In which case, during a day time, a roof absorbs a solar heat, resulting in the increase of temperature in the vessel. Expanded air pressurizes a sea surface to press up the sea surface, and sea water is moved through a discharge port 24 to storage water tanks 12 and 13. This method enables execution of pumping up at a low cost.

Abstract: PURPOSE:To measure the amount of deformation of a sample quickly and highly accurately by providing an electrooptic element which changes the index of refraction in proportion to the intensity of the electric field, and changing the position of either the object light or the reference light periodically. CONSTITUTION:The linearly polarized light of the laser light projected from a laser source 1 enters a polarization beam splitter 2. The amount of the S component of the laser light is adjusted by a 1/2 wave plate 3. The laser light is then reflected by a reflecting mirror 4, and divided into a reference light and an object light through a half mirror 7. After a sample 21 is minutely deformed and the wave plate 3 is rotated to adjust the amount of the laser light, the reference light beam is cast to a single crystal plate 20 and the object light beam is cast to the sample 21. Two phases of the scattering light reflected by the sample 21 are changed corresponding to the amount of deformation of the sample 21, and the scattering light and the reference light interfere with each other to generate interference fringes. A voltage of a triangular wave is applied to an electrooptic element 41. The interference fringes which periodically change are photographed by a camera 31, recorded by a VTR 32 and analyzed by an image analyzing part 34. Accordingly, the amount of deformation of the sample 21 is operated.

IPC: B41J2/16
Filed: 1990-11-28
Abstract: PURPOSE:To effectively seal a gap generated at contact surfaces of a base material and a ceiling material by holding an ink jet recording head with a discharge port directed obliquely downward, and pouring resin at a position surrounded by the frame of a structure. CONSTITUTION:A dispenser is positioned at an opening surrounded by a frame 5B of a chip tank 5. When resin 8 in the dispenser is poured in the opening, the resin is also introduced into a gap between an upper surface of a heater board 3 and a lower surface of a ceiling member 4. Since an ink jet recording head 1 is held with a discharge port 4B directed obliquely downward, the resin is fed to the port 4B side by its own weight along the gap, and arrived at the rear surface of an orifice plate 4C. The resin is further introduced into a gap between the rear surface of the plate 4C and the front surface 3A of the board. Thus, the gap between the board 3 and the member 4 is completely sealed with the resin 8.

In this case, the MTF characteristic value is shown by the shift quantity of defocus of an MTF peak point (focused point) by a comparatively low detection frequency and defocus of the MTF peak point of a comparatively high detection frequency. In such a way, the focal detection of an object to be photographed in the periphery of a screen can be executed quickly and with high accuracy.

Title: Composite metallic plate and production thereof
Inventor: HARADA NOBUAKI
IPC: C08F210/02
Filed: 1990-11-28
Abstract: PURPOSE:To contrive higher vibration-damping property, adhesion and heat resistance, by adhering metallic sheets to both sides of an intermediate layer comprising an peroxide cross-linked product of an ethylene copolymer containing unsaturated carboxylic acid monomeric units in a specified proportion by weight. CONSTITUTION:A thin layer of a composition comprising a peroxide and an ethylene copolymer containing 10-35wt.% of unsaturated carboxylic acid monomeric units is placed between two metallic sheets, and the copolymer is subjected to cross-linking simultaneously with or after adhesion of the composition to the metallic sheets. The amount of the unsaturated carboxylic acid monomeric units in the ethylene copolymer is 10-35wt.%, preferably 15-30wt.%. Where the amount of the monomeric units is too small, adhesion of the composition to the metallic sheets and vibration-damping property of the resulting product are unsatisfactory, and the melting point of the copolymer is not low enough to avoid difficulties in forming a thin layer of the composition while preventing the peroxide from decomposing.

Title: Crawler belt covering material for heavy machine and its manufacture
Inventor: TANISHITA ISAMU
IPC: B62D55/24
Filed: 1995-12-13
Abstract: PROBLEM TO BE SOLVED: To provide a crawler belt covering material for a heavy machine with high durability and accurate running derivability without damaging a running surface by connecting a main body, which has a grounding face at one side and is molded with elastomer to form an elastic soft layer on the grounding face side and a hard layer on the core body side, to a core body in one unit. SOLUTION: As force transmitted to the hard position 1b is dispersed over almost all area from the joint of the hard portion 1b while being partially absorbed in the soft portion 1a, a heavy machine stably runs without lopsided load applied to local points including the peripheral edge and resulting damage such as crack to a main body 1. The hard portion 1b as the second main body located on the outsidemost layer of the main body 1 can be molded relatively thinner and prevented from nonuniformity in material (pits in the surface) when being thicker during molding of the main body 1, so that the main body 1 is expected to be formed in a good condition, showing a good appearance and improving its molding efficiency with plural decentralized processes rather than one process.

Title: Manufacture of synthetic resin foamed heat insulation material
Inventor: FUJIIKE SHIGERU
IPC: F16L59/00
Filed: 1993-12-22
Abstract: PURPOSE:To decrease a surface blister by minimizing a void generated in a contact part of a synthetic resin foaming stock solution with a front surface material by a method wherein nappy fiber is made to exist on an inner surface of the front surface material existing in a foamed completion attainment part. CONSTITUTION:A synthetic resin foaming stock solution is poured by stirring after sticking a nappy fiber 4 to an inner surface of a front surface material 1 of a heat insulation material. Consequently, a void generated instantaneously is diffused since air and gas scattered from a synthetic resin foaming stock solution are transferred in a 360 deg. space and in a space among naps of the nappy fiber, and lastly extruded outside. The void is decreased thus by the nappy fiber, adhesive strength is improved by a linked effect of the front surface material, nappy fiber, and synthetic resin foamed material, and a surface blister is restrained from occurring. As a method for raising fiber, there are nap- raisings by a flocky treatment and with a needle fabric. As a worsted blanket, ordinary ones of rayon, cotton, hemp, etc., are used. As the synthetic resin foaming stock solution, rigid polyurethane resin, resol type phenolic resin, etc., are used.
