摘要:
The present invention provides a rubber product with a fiber reinforcing layer, which is enabled to bond a rubber layer and a fiber reinforcing layer by a formalin-free adhesive with an adhesive strength equal to or more than that of a formalin-containing RFL. The rubber product with the fiber reinforcing layer includes a rubber layer containing a nonpolar rubber or a diene-based rubber, and a fiber reinforcing layer containing a woven fiber cord having a polarity. The rubber layer and the fiber reinforcing layer are stacked and bonded with an adhesive containing a triazine thiol and a diene-based rubber.

摘要:
The invention relates to a cellulose acylate film whose thickness is from 10 μm to 40 μm, retardation in plane at a wavelength 590 nm, Re(590), satisfies 40 nm≦Re(590)≦70 nm, and retardation along the thickness direction at a wavelength 590 nm, Rth(590), satisfies 90 nm≦Rth(590)≦150 nm; and which comprises at least cellulose acetate propionate, cellulose acetate butyrate or cellulose acetate propionate butyrate, having a total degree of acyl substitution of from 2 to 2.35 and a degree of propionyl and/or butyryl substitution of from 0.6 to 1.1.
摘要:
A nitrile rubber-polyvinyl chloride polyblend rubber composition containing a paraffinic process oil alone or a combination of paraffinic process oil and one or more other lubricants, which is used as molded articles such as door mirror bracket. The molded articles of the present invention give a much lower sliding resistance.

A communication (comm) apparatus coupled to a telephone (tel) line comprises a base having a tel portion, a fax portion including a fax modem, a first switch for switching the mode between fax and tel, and a first wireless comm portion, and at least a cordless unit having a second wireless comm portion for communicating with the base, and a second fax portion including a recording/reading portion. The cordless unit may further comprise a second tel portion and a second switch for switching the mode between fax and tel wherein the base can change the second switch to the other mode if necessary. A cordless phone may be further provided. In response to a fax call, the base holds the line but the cordless unit does the fax procedure and if there is no response from the cordless unit within a given interval, the line is disconnected wherein each of cordless unit responds with a different delay time to have a priority. During facsimile comm, an erroneous on-hook is neglected. A cordless unit has a guidance portion for outputting a given message and if there is an extension call to other cordless unit in fax mode, the other cordless unit transmits a control signal and the cordless unit outputs the message. The wireless comm portion has multi-channels to provide a comm between cordless units even when a cordless unit receives a fax signal.
摘要:
A polarizing plate comprising a polarizing film, and on one surface thereof, a cellulose acylate film having a thickness of equal to or less than 77 micro meters, and a layer having a negative photoelastic coefficient is disclosed.
摘要:
In manufacturing a double-layered or a multi-layered printed wiring board, a layer of metamorphic substance, which is created by transmuting a substrate material, is formed on an inner wall of a hole during a perforation process of the substrate utilizing radiation energy. The layer of metamorphic substance prevents conductive materials constituting electrical connection means formed on the inner wall of the hole from dispersing over a surface of the substrate or permeating into the substrate.

A rolling mill for metal foil includes a pair of work rollers having axes in parallel to each other for subjecting a sheet material being supplied therebetween to strip processing, two pairs of intermediate rollers arranged so that the intermediate rollers of each pair are in contact with one of the work rollers and have axes in parallel to the axis of the contacting work roller, and two pairs of backup rollers arranged so that the backup rollers of each pair are respectively in contact with one pair of the intermediate rollers. Each pair of intermediate rollers and the pair of backup rollers in contact with the pair of intermediate rollers impart roll load to the work roller in contact with the pair of intermediate rollers. The rolling mill enables the production of large-width metal foil too thin to be self-supportable in shape with ease and high precision.
