A wet frictional material having a high heat resistance, excellent durability and superior initial conformability. The wet frictional material contains a fiber base material, a filler, a frictional adjustment agent and a thermosetting synthetic resin. The thermosetting synthetic resin comprises a silicone resin represented by the following average formula. The silicone resin contains a trifunctional unit (RSiO.sub.3/2) (where R represents a substituted or unsubstituted monovalent hydrocarbon group) in an amount of from 40 to 100 mol % of units constituting the silicone resin:(R.sup.1).sub.a (OR.sup.2).sub.b SiO.sub.(4-a-b)/2where R.sup.1 represents a substituted or unsubstituted monovalent hydrocarbon group, and R.sup.2 represents a hydrogen atom or an organic group having from 1 to 10 carbon atoms, and 0.2.ltoreq.a.ltoreq.1.8 and 0

A process for preparing a polyester-modified silicone resin comprises mixing an alkoxysilane and/or its hydrolyzate, i.e. an alkoxysiloxane, and a polyester resin having at least two hydroxyl groups in the molecule, and subjecting the mixture to hydrolysis and polycondensation reactions in the presence of an acid catalyst. This process is performed by a continuous one-stage reaction sequence including hydrolysis, polycondensation and modification and is simplified. A composition comprising the polyester-modified silicone resin is also described. The composition comprising organozinc compounds along with the modified silicone resin is significantly improved in heat resistance and color-difference.

A method of producing an optical fiber preform includes preparing a glass preform that has a hole extending in a longitudinal direction formed on one end of the glass preform in such a manner that a length of the hole is equal to or less than half of an entire length of the glass preform, synthesizing a porous glass preform by depositing glass particles on an outer circumference of the glass preform having the hole formed on the end, and sintering the porous glass preform after arranging the porous glass preform in such a manner that the end having the hole formed thereon points downward and the hole is open to the air.

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.
