PURPOSE:To provide the liquid crystal display body having high display quality and reliability by setting the specific resistance of a liquid crystal/high polymer composite film at nearly the same value as a liquid crystal alone and using a lateral type MIM element as a driving element. CONSTITUTION:A high-polymer matrix 1 of a grid shape or mesh shape, etc., is previously formed by curing a photosetting resin and a liquid crystal is penetrated into this matrix 1. Since the direct contact of the photosetting resin in a low molecular state and the liquid crystal does not arise, the low molecular impurities do not infiltrate the liquid crystal. The specific resistance of the liquid crystal/high polymer composite film is, therefore, maintained at nearly the same specific resistance of the liquid crystal alone. Further, the MIM element can increase the voltage to be impressed to the liquid crystal material as compared with a TFT material and, therefore, this element is convenient for driving the liquid crystal/high polymer composite film having the threshold voltage slightly higher than the threshold voltage of the ordinary liquid crystal materials. Further, the capacity of the element itself is small and, therefore, the capacity ratio between the liquid crystal material and the element is increased by decreasing the capacity of the MIM element without reducing the thickness of the liquid crystal cell.

PROBLEM TO BE SOLVED: To provide a long periodic wave reducing countermeasure structure capable of suitably dissipating a long periodic wave in a small scale. SOLUTION: This long periodic wave reducing countermeasure structure is constituted by arranging a front wall 11 by juxtaposing a plurality of caissons 20 with a clearance for constituting a water communication port 13, by arranging the front wall 11 with a retarding part 12 on the front side of a rear wall 10 composed of a marine structure such as a ship alongside quay, a breakwater and a revetment in a harbor.

Long periodic wave reducing countermeasure structure

Anti-reflectant breakwater useful for vertical breakwaters and port quays and the like and designed to reduce the reflectivity or waves reflected in a wide range of frequencies wherein the basic structure is a prefabricated caisson formed by cells (11, 12, 13, 14 y 15) in which at least one row thereof (11) are prismatic chambers (1) which have openings, perforations or slots (2, 8, 17, 19) and in which at least one row of cells (12) located behind the previous row is eliminated in order to create an open chamber (3) formed between the preceding ones and the reflectant rear wall (4), in such a way that the filling/emptying dynamic of the prismatic chambers (1) is different from the filling/emptying dynamic of said open chamber (3).

PURPOSE:To obtain the titled compound useful as a synthetic intermediate for cephalotaxine useful as a remedy reagent for leukemia in high yield by easy operations, by cyclizing a benzazepine derivative as a self-catalyst in a basic solvent or on a solid adsorbent. CONSTITUTION:2 -Oxo-[5, 8, 9, 10-Tetrahydro -6H- 1, 3-dioxolo[4, 5-h]pyrrolo [2,1-b][3]benzazepin-11-yl]-1-propanone as a self-catalyst is cyclized in a basic solvent, e.g. (C2H5)3N-CH3OH, or on a solid adsorbent, e.g. Al2O3, to give the aimed substance of formulaI. The starting substance is obtained by acylating an enamine and an anhydride of formula II, and decomposing the excess unreacted anhydride with methanol added thereto.

PURPOSE:To moderate fluctuation in torque of a driving shaft in a seedling planting mechanism by improving the shape of a cam for driving a seedling pushing tool of a rotary type seedling planting mechanism. CONSTITUTION:A small-diameter cam surface (19a) for projecting operation of a seedling pusher 15 and a large-diameter cam surface (19c) for forced retreat are formed on the outer periphery of each cam 19. The shape of the cam 19 is further set as follows. When a cam follower (18a) for either of the two cams 19 and 19 acts on the small-diameter cam surface (19a) in the intermediate rotation phase of the cam surfaces (19a) and (19c) to urge and project a seedling pushing tool 15, a cam follower (18a) for the other cam 19 acts on a steep slope stepped part (19d) leading to the large-diameter cam surface (19c) and attains a state of operating the seedling pushing tool 15 to retreat against the urging force.

PURPOSE: The proposed burner is composed of a main burner unit having opposed flame port sections facing each other, and the flame port sections which meet at right angles with the above opposed flame port sections, and a switching unit which switch over fuel supply to both flame port sections and only to the flame port sections meeting at right angles with the opposed flame port sections, so that switching of combustion capability may thus be availabe and also a complete combustion of all kinds of fuels may also be insured.
