Title: Prevention of coastal erosion
Inventor: OE TAKESHI
IPC: E02B3/12
Filed: 1989-12-25
Abstract: PURPOSE:To prevent coastal erosion and to enhance environmental protection by a method wherein boxes with sand filled therein are formed of resin concrete piles that are erected on the coast and water permeable boards that are installed in grid shape between the piles, and the water-permeable boards are made to allow seawater only to penetrate therethrough, preventing the sand from passing. CONSTITUTION:A pile 1 is molded by pouring material made by mixing and agitating silica sand, calcium carbonate and resin with hardening agent added into a mold for the pile 1 whose four sides respectively have a groove 2 that is formed at the center of the side in the longitudinal direction. A material made by mixing and agitating round gravels 5 and resin with the hardening agent added is poured into a flat board-like mold, and thereby a water-permeable board 3 is formed. The piles 1 are then erected at appropriate intervals on a coast so that the height of each of the piles becomes higher as it approaches the land side. The water-permeable boards 3 are then fitted into the grooves 2, 2 of the piles 1, 1 so that the boards are stacked one after another and boxes 4 are formed with the water- permeable boards assembled in grid shapes. The boxes 4 are then filled with sand. As the water-permeable boards 3 allow seawater only to penetrate therethrough with the sand kept inside, intercepting solid substances from passing, coastal erosion can be prevented.

Title: Production of oxygen
Inventor: HAGA TETSURO
IPC: B01D53/04
Filed: 1989-12-28
Abstract: PURPOSE:To obtain high oxygen yield within a short time with an adsorbent reduced in its use amount by supplying a necessary amount of oxygen to an adsorbing tower at the time of an oxygen injection process supplying oxygen gas to the adsorbing tower and discharging desorbed gas. CONSTITUTION:An adsorbing process for supplying raw material gas (e.g. air) to adsorbing towers 1, 2 packed with an adsorbent (e.g. synthetic zeolite) to take out the oxygen gas adsorbed and separated under pressure, a pressure reducing and regenerating process for reducing the pressure in the adsorbing towers 1, 2 to regenerate the adsorbent and an oxygen injection process for supplying the oxygen gas to the adsorbing towers 1, 2 to discharge desorbed gas are successively repeated to prepare the oxygen gas. In this case, the supply of the oxygen gas to the adsorbing towers 1, 2 is stopped before the breakthrough of the concn. of oxygen in the desorbed gas. As a result, high oxygen yield can be obtained within a short time by the adsorbent reduced in its use amount.

Abstract: PROBLEM TO BE SOLVED: To make it possible to suppress condensation and to hold the room temperature constant by disposing silica gel for absorbing an discharging moisture at many recesses formed on the surface of a base material, and coating the surface thinly with a resin. SOLUTION: A film 12a is formed by coating the surface of thin paper 11 as a base material with an ink mixed with heating foaming agent, heated to foam it, and solidified in the state that protrusions made of bubbles are formed. Then, the surface is ground to form recesses 12 of about 1 to 5μm, and B type silica gel is rubbed into it. Thus, the gel 13 is introduced into the recesses 12. The surface is coated with a synthetic resin paint to form a coating with a thin synthetic resin 14 having moisture permeability. The particle size of the gel 13 of this case is 74μm or less. In this manner, condensation is suppressed to make it possible to hold the temperature in a room constant.

Title: Liquid crystal overhead projector
Inventor: KAWAHARA YUKIO
IPC: G02F1/137
Filed: 1989-12-28
Abstract: PURPOSE:To prevent the occurrence of a double image caused by coloring by providing a polarizing plate before or behind a lens part which condenses reflected light from a mirror Fresnel lens and using an ECB type liquid crystal display element as a liquid crystal display element. CONSTITUTION:The liquid crystal display element 9' which does not have the polarizing plate on its one side is provided on the mirror Fresnel lens 2 so that the side of the element 9' where the polarizing plate 8b exists may be opposed to the mirror Fresnel lens 2. Then, the polarizing plate 8c is provided before or behind the lens part 4 which condenses the reflected light from the lens 2, and the ECB type liquid crystal display element is used as the liquid crystal display element 9. By using the ECB type liquid crystal cell as the liquid crystal cell 9', color display is accomplished and a dark state is realized, especially, in the case of using a VAN type. Since the control of the brightness of dots and the control of color developing are simultaneously performed in accordance with the change of the oriented state of liquid crystal by using the ECB type liquid crystal cell 9', it is needless to use a color filter. Thus, the coloring and the prevention of the occurrence of the double image are compatibly performed.

Title: Oil level detection device within closed container according to ultrasonic wave
Inventor: MASUHARA YUTAKA
IPC: G01F23/28
Filed: 1991-12-25
Abstract: PURPOSE:To enable an oil level position within a tank to be detected accurately by fixing a parallel ultrasonic reflection plate for a side wall within a sealed type metal tank and then providing an ultrasonic probe which can move up and down on an outer-wall surface of the tank so that the probe opposes the wall. CONSTITUTION:A reflection wave is scanned by moving an ultrasonic probe 11 in upper and lower directions. An ultrasonic flaw-detection machine 12 detects arrival time and strength of the reflection wave according to the reflection wave. A high detection sensitivity can be obtained since the probe 11 detects a reflection wave with a large strength from an ultrasonic reflection plate 21. Also, arrival time and strength of the reflection wave change in steps corresponding to a difference in propagation characteristics of ultrasonic wave at liquid-phase and gaseous phase parts of fluorocarbon with a liquid face 7 as a boundary in scanning process. By detecting this step-shaped change point, a position of the liquid face 7 can be known. By marking a detection liquid-face position on an outer-wall surface of the tank at the time of initial measurement, presence or absence of failure of closing performance can be judged easily according to deviation of the liquid-face position which is detected at the time of periodical inspection.
