Title: Production of steel sheet for porcelain enameling
Inventor: ENOKIDO HIROFUMI
IPC: C22C38/00
Filed: 1998-03-16
Abstract: PROBLEM TO BE SOLVED: To effectively prevent the development of fine bulged defect at the time of annealing and at the time of burning for enameling by executing the heat of a steel slab at low temp. of a specific temp. or lower after continuously casting the steel slab containing specific contents of B and N. SOLUTION: The steel sheet contains 0.010-0.015 wt.% B and 0.0060-0.0100 wt.% N in addition to the basic component in the steel sheet for porcelain enameling. Molten steel having this composition is made to the slab by continuously casting and successively, the heating is applied to this slab and this heating temp. is limited to <=1200 deg.C. In this way, even in the case of concentrating C and B at the cracked part in the inner part of the slab, since the liquid phase is not apparent and the solid phase is left as it is, the development of the crack is restrained even in the case of executing the width rolling reduction. Further, it is desirable to control the steel component so that an SB value shown with SB (ppm)=B (ppm)-O (ppm)-×22/48-N (ppm)×11/14 becomes <=50 ppm.  Wherein, B, O and N show the total boron content, total oxygen content and total nitrogen content, respectively.

Abstract: PURPOSE: To obtain image information having a wider dynamic range than a dynamic range of a single image pickup element as a signal of an image by synthesizing plural signals obtained under different sensitivity setting conditions with one and same image pickup element. CONSTITUTION: In the image input device, an incident light 101 is converted into an electric signal by an accumulation image pickup element 102 using charge amplification in the inside of a semiconductor such as avalanche phenomenon. The sensitivity of the image pickup element 102 is variable by a sensitivity controller 103. A signal correction device 104 decides an output signal level for each picture element proportional to an incident luminous quantity based on an output of the image pickup element 102 and the sensitivity setting condition of the sensitivity controller 103 and stores it to a frame memory 105. Then signals obtained by picking up an object under different sensitivity setting conditions are synthesized by an image processing circuit 106 to form a video signal by one picture element and the signal is outputted to a monitor 107 and a storage device 108 or the like.

Title: Ferroelectricsmectic liquid crystal composition
Inventor: KORISHIMA TOMONORI
IPC: C09K19/46
Filed: 1986-03-26
Abstract: PURPOSE:To obtain a liq. crystal compsn. having an excellent water resistance as well as a high spontaneous polarization, by incorporating a specific compd. in a ferroelectric smectic liq. crystal compsn. CONSTITUTION:A ferroelectric smectic liq. crystal compsn. contg. a compd. of the formula I. In the formula I, R is a 1-12C alkyl or alkoxy; a ring A and a ring B are each independently 1,4-disubstituted phenylene, trans-1,4- disubstituted phenylene or trans-1,4-disubstituted cyclohexylene; X and X' are each independently a single bond, -COO-, -OC-, CH2-CH2-, -CH2-O- or -O-CH2-; n is an integer of 0 or 1; and * is a center of optical activity. In the compd. of formula I, R is alkyl or alkoxy, and the number of carbon atoms thereof is 1-12, preferably 2-8 since too small a carbon number leads to a high m.p. while too large a carbon number leads to a high viscosity. Further, it is preferred that R be of a straight chain rather than a branched chain since the max. temperature of a liquid crystal exhibiting a smectic C phase is high when it is mixed with a compd. which exhibits liquid crystalline properties.

Title: Composite artificial blood vessel
Inventor: OKUDA YASUHIRO
IPC: A61F2/06
Filed: 1991-03-29
Abstract: PURPOSE:To obtain the interstitial property good over a long period of time after implantation by compounding a biotissue inductive material and antithrombotic material into stretched polytetrafluoroethylene (PTFE) having a long fiber structure which is excellent in the infiltration property of the biotissue and an integral structure which is dynamically excellent. CONSTITUTION:A liquid oil lubricant is intimately mixed into the unsintered powder of the stretched PTFE and the mixture is extruded to a tube shape by a ram type extruder. The extruded tube is heated by continuously applying a temp. gradient between the inside and outside surfaces of the tube. The rearrangement of the fiber- knot structure arriving at the outside surface from the inside surface of the tube takes place and the tube is further stretched more than before the treatment, by which the long fibered parts and short fibered parts are obtd. The material having a biotissue induction effect and the antithrombotic material are applied respectively independently or after being mixed with another high-molecular material on the parts constituted of the long fibers. The parts constituted of the short fibers maintain the structure as the tube since the short fiber parts thereof continue like network from the inside surface to the outside surface of the tube wall in the circumferential direction of the tube, thereby imparting tear and tensile strength to the tube.
