IPC: C21D8/02
Filed: 1997-04-22
Abstract: PROBLEM TO BE SOLVED: To improve plating adhesion to a greater extent in the method of manufacture of a hot dip galvanized steel sheet by the use of a hot rolled steel sheet with oxide scale as a starting sheet for plating. SOLUTION: A steel slab is hot-rolled, finish-rolled, cooled down to <=650 deg.C at (50 to 150) deg.C/s cooling rate, and then coiled, by which a hot rolled starting sheet where the average peeling quantity of the oxide scale adhering to the surface and rear surface of hot rolled steel sheet is regulated to <=10 g/m<2> is prepared. After the hot rolled steel sheet is subjected, if necessary, to skin pass rolling, reducing treatment is applied, without acid pickling, at least to the surface of the oxide scale in a reducing-gas atmosphere of >=300 deg.C and then hot dip galvanizing is applied, or, the hot rolled steel sheet is subjected to skin pass rolling and then to reducing treatment for the oxide scale without acid pickling.

Title: Antenna system
Inventor: ITO KOICHI
IPC: H01Q21/24
Filed: 1996-05-15
Abstract: PROBLEM TO BE SOLVED: To attain effective and excellent transmission reception by configuring a square loop radiation element with four slots where a phase difference between the adjacent slots is 90 deg. so as to use a coplaner feeder through excitation by a circularly polarized wave. SOLUTION: A square shaped loop radiation element 4 is configured by synthesizing four slots 4a-4d where a phase difference between the adjacent slots is 90 deg.. Thus, when a magnetic field is generated in a slot line 3, a right- handed directional magnetic field M is generated and then a right-handed circularly polarized wave is generated. A resonance frequency is obtained from the radiation element 4 by selecting the length of the slots 4a-4d to be λ/4 (λ is a wavelength with respect to a center frequency of an object frequency band). Furthermore, the right-handed circularly polarized wave is generated by feeding the radiation element 4 though the connection of the slot line 3 to a point P1 and the left-handed circularly polarized wave is generated by feeding the radiation element 4 though the connection of the slot line 3 to a point P2. Thus, the effective and excellent transmission reception is attained by using a coplaner feeder through the excitation of the circularly polarized wave.

Abstract: PURPOSE: To prepare the title compound useful as a medicine, etc., in high yield, by reacting a 17-keto-steroid with a methyl metal reagent, wherein the reaction is interrupted by adding a specific aqueous solution to the system, and repeated two or more times.  
     CONSTITUTION: A 17β-hydroxy-17α-methylsteroid (e.g. 17α-methyl-17β-hydroxy- androst-4-en-3-one) is prepared by reacting the corresponding androstane- or estrane-type steroid having a carbonyl group at the 17 position (e.g. 3-ethoxy-androsta-3,5-dien-17-one) with a methyl metal reagent.

Title: Spilled oil recovery apparatus
Inventor: FUKUDA SHIYOUZOU
IPC: E02B15/00
Filed: 1977-10-13
Abstract: PURPOSE: To accomplish efficient recovery of oil spilled over the surface of sea by means of a floating oil tank provided behind a slant plate for concentration of oil and water arranged in a oil water inflow passage in such a manner that the bottom plate of the passage is elevated at the front and rear ends above the lower end of the tank.  
     CONSTITUTION: As a spilled oil recovery apparatus is towed, water flows from the lower layer down below the front end 27a of the bottom plate while oily water from the upper layer hits against a metal screen 40, a slant plate 21 and projected pieces 23 and is divided into fine particles through breakage of oil film. Then, the oil thus finely granulated goes up along the slant plate and flows into a coares granulation tank 36 for oil drops, where it is reduced into coares particles. Such a large wave as to reach the upper end of the slant plate 21 is divided to the right and left at a V-shaped tip, thurns along a roughly arc-shaped wall surface 31a via a wave baffle chamber and then, flows to the tank 36. The oil flows into a floating oil tank 24 from a lower opening 39 to allow the oil drops to float up while an execess of water flows into a bottom opening 24. This prevents the inflow of the water in the lower layer, resulting in a gain in the inflow of oil from the  upper layer. In this manner, the recovery efficiency of the oil can be improved
