Abstract: PURPOSE:To secure an optimum type of a ship without performing any model tests, by systematically changing each specification for a hull form under the condition that displacement is constant and a water plane area is below the limited value, while calculating such a form as making the total amount of viscous pressure resistance, frictional resistance and peeling resistance minimal, by means of a numerical expression. CONSTITUTION:Those of viscous pressure resistance Rvp obtainable with pressure on a hull surface integrated to its whole surface, frictional resistance RF obtainable with shearing stree on the hull surface integrated to its whole surface and peeling resistance Rsp or hull resistance in the more rearward than a peeling point are all found with each numerical expression. On the condition that displacement is constant and a water plane area is below the limited value, each parameter showing each hull form is systematically changed whereby calculation for each resistance value takes place. And, such a hull form as making viscous resistance in the hull as the total amount of each resistance value is found. According to this method, such an optimum hull form as making the hull resistance smaller is securable without performing any model tests which must be repeatedly performed over and over.

Filed: 1996-08-14
Abstract: PROBLEM TO BE SOLVED: To provide an adjusting method, for the position of a light-receiving lens in an optical sensor, in which the position of the light-receiving lens can be adjusted in a short time. SOLUTION: By using a light-receiving lens, reflected light from a reflecting plate 7 is condensed on a light-receiving element 5. The light-receiving element 5 detects the position of the reflecting plate 7 on the basis of the condensing position of the reflected light, and an optical sensor outputs an ON/OFF signal according to whether a reference distance A to the reflecting plate 7 is far or near. When the position of the light-receiving lens is adjusted, an adjusting means first moves the light-receiving lens from am initial feed position P0 by every 15αμm until a sensor output is changed over from an ON operation to an OFF operation in a state that the reflecting plate 7 is moved to the position of a distance B far from the reference distance A.  When the sensor output becomes the OFF operation, the adjusting means moves the light- receiving lens by every αμm until the sensor output becomes the OFF operation from the ON operation again in a state that the reflecting plate 7 is moved to the reference distance A, and the light-receiving lens is moved to a prescribed position P2 .

IPC: G01N27/26
Filed: 1986-09-11
Abstract: PURPOSE:To improve the workability of a gel medium, by getting an additional small amount of water cellulose derivative contained in a polyacrylamide based water gel medium for electrophoresis. CONSTITUTION:An aqueous solution for forming an acrylamide gel which contains an acrylamide based compound, a crosslinking agent and a small amount of water-soluble cellulose derivative is cast into a glass mold which is made of two sheets of glass plates having a spacer plate at the periphery thereof arranged in opposition. The gel forming solution is irradiated with a mercury lamp of about 100W, causing a crosslinked polymerization to form a polyacrylamide water gel medium film for electrophoresis. This can enhance the hardness of a gel film maintaining electrophoretic characteristic suitable for separation analysis of a high polymer substance such as protein. This facilitates the punching of a sample injection slit and improves workability with a smooth cut surface of the gel film.
