摘要:
A catalyst component for olefin polymerization which comprises an intimate mixture of: Component (A1) which is a solid component for Ziegler catalysts comprising titanium, magnesium and a halogen as essential components in a particulate form; and Component (A2) which is a compound selected from the group consisting of inorganic oxides, inorganic carbonates, inorganic sulfates and physical or chemical mixtures thereof in a particulate form; wherein Component (A2) is employed in a weight ratio to Component (A1) from 0.001 to 0.5 and has an average particle diameter smaller than that of Component (A1). The catalyst component may be of a structure such that the particulate inorganic material, Component (A2), adhere to or cover particles of a solid component of a Ziegler catalyst, whereby fluidity of the Ziegler catalyst component is improved.

In a wide area Ethernet network, an edge side gateway (EGW) acquires layer 2 tunneling control information from an authentication server when a PADI is received from a user terminal, stores the correspondence between the source address of the PADI and the layer 2 tunneling control information in its management table, encapsulates the PADI in accordance with the layer 2 tunneling control information, and transmits the encapsulated PADI packet to the wide area Ethernet network. A core side gateway (CGW) having received the encapsulated PADI packet stores the correspondence between the tunneling control information and the source address extracted from the received packet in its management table, and forwards the PADI obtained by decapsulating the received packet to a broadband access server. Thereafter, each of the EGW and CGW forward received packets for the user after converting their format by referencing to the management tables.

A search for copyright-related information contained in image data is conducted. If no such information is detected, a database is queried to determine whether it contains copyright-related information corresponding to the image represented by this image data. Information relating to a copyright in accordance with the result of querying the database is added onto the image data. This prevents the unauthorized copying of a copyrighted article in an environment in which digitized copyrighted articles can be exchanged by networking and electronic filing.
摘要:
An object of the present invention is to provide a single-phase film of a metal sulfide with good quality, and a method for preparing a metal sulfide film at a low cost in a convenient manner. The present invention provides a preparation method of a metal sulfide film, comprising the steps of providing metal halide, such as iron halide (FeCl3, FeI3, FeBr3, FeCl2, FeI2 and FeBr2), as a first raw material and a thioamide compound, such as thioacetamide, as a second raw material, preferably vaporizing these raw materials and reacting them at atmospheric pressure; and a metal sulfide film prepared by this method.
摘要:
An electronic endoscope system includes an electronic endoscope and a processor to which the electronic endoscope is connectable. The processor includes a signal processor for displaying the images captured by the electronic endoscope, while adjusting the color balance thereof, and a memory holding an endoscope database. The processor further includes a CPU that retrieves endoscopic information from a memory of the electronic endoscope, which includes compensation data for white balance adjustment of the processor. The CPU registers the electronic endoscope with the endoscope database by storing the retrieved endoscopic information into the endoscope database when the white balance readjustment of the processor is required.
摘要:
A software architecture for task oriented applications. The architecture utilizes a wrapper as an intermediate structure between an external calling application and a wrapped component or module. The wrapper is written in a script language and acts as a bridge between the external application and the wrapped component. Data is transferred among components through the intermediary of a table of contents (TOC) file which contains data attribute information and a link to the actual data file.
摘要:
A method of manufacturing a metallic fiber in which from a convergent extended wire, which is formed by a metallic fiber and a matrix member which is formed of a metallic material and whose dissolvability is higher than the dissolvability of the metallic fiber, the matrix member is continuously dissolved and removed by an electrolytic processing in a plurality of electrolytic tanks which are arranged in the conveying direction of the convergent extended wire, wherein: the convergent extended wire is passed through electrolytes in the plurality of electrolytic tanks, which are arranged in the shape of a gentle convex arch at the vertical direction upper side which includes the conveying passage of the convergent extended wire, the convergent extended wire is passed above a plurality of feeding devices which are provided at the outer sides of the electrolytes and which are disposed in the same arch-shape so as to correspond to the electrolytic tanks, in each of the plurality of electrolytic tanks, the metallic fiber is maintained in one of a cathode reduction area and a passivation area, or alternatively, anode current is maintained at a predetermined potential which is closer to 0, and the matrix member is anode-electrolyzed. At this time, a method of manufacturing the twine of metallic fibers, further including the step of: intertwining the convergent extended member in the unit of two to four before the electrolytic processing, while the convergent extended member is formed by a forming device in a spiral shape whose diameter is larger than the diameter of a closely-intertwined twine.
