There is provided a supporting member having excellent durability and an apparatus including the supporting member. The supporting member includes an elastic member and a plurality of block members formed thereon. The supporting member is deformable from a shape in which end surfaces of the block members are in contact with each other to a shape in which the end surfaces are separated from each other. The elastic member includes a fixed region whose deformation is restricted by being fixed to a bottom surface of the block member, and the supporting member includes a flexure reduction unit for reducing flexure at a position near the fixed region of the elastic member.

Supporting member, conduit supporting device, and processing apparatus provided therewith

The present invention provides a sealing sheet containing a flame retardant adhesive sheet having a flame retardant-containing adhesive layer, wherein the flame retardant-containing adhesive layer has a void content of 5-40%.

Sealing sheet

A PSA sheet is provided, having an adhesive face formed of an acrylic PSA layer comprising an acrylic polymer. The PSA sheet has a peel strength of 5 N/10 mm or greater. The peel strength is measured as such that the adhesive face is directly adhered to an ethylene-propylene-diene rubber surface and after 20 minutes, peeled in the 180&#xb0; direction at a tensile speed of 50 mm/min.

Pressure-sensitive adhesive sheet and use thereof

A pressure-sensitive adhesive composition is provided for forming an acrylic pressure-sensitive adhesive that constitutes an adhesive face. The pressure-sensitive adhesive composition comprises an amino group-containing (meth)acrylate as its monomeric component. The amino group-containing (meth)acrylate accounts for 5% by mass or more of all monomeric components of the pressure-sensitive adhesive composition.

Pressure-sensitive adhesive composition

The present invention relates to an acrylic pressure-sensitive adhesive including: a) an acrylic polymer containing, as a monomer unit, an alkyl (meth)acrylate including an alkyl group having 1 to 20 carbon atoms in an amount of 50% by weight or more; and b) a tackifier resin, in which the acrylic polymer a) contains two kinds of monomer units having a difference in solubility parameter (SP value) of 0.2 (MPa)or more, each in an amount of 15% by weight or more.

Acrylic pressure-sensitive adhesive, acrylic pressure-sensitive adhesive layer and acrylic pressure-sensitive adhesive tape or sheet

A resin production apparatus of the present invention includes: a reactor vessel having a vessel main body which polymerizes an ingredient to produce a thermoplastic synthetic resin which solidifies at room temperature and storing the synthetic resin in the molten state, an output mechanism disposed at a bottom part of the vessel main body, which outputs the synthetic resin in the molten state, and a temperature adjustment mechanism which adjusts temperatures of the vessel main body and the output mechanism so as to maintain the molten state of the synthetic resin; a cooling mechanism arranged below the reactor vessel, which continuously cools and solidifies the synthetic resin output from the output mechanism; and a crushing mechanism which crushes the synthetic resin fed out from the cooling mechanism.

Resin production apparatus and resin production method

A single-layered acrylic pressure-sensitive adhesive tape having a pressure-sensitive adhesive layer formed of an acrylic pressure-sensitive composition. The acrylic pressure-sensitive adhesive composition contains an acrylic polymer (A) and a (meth)acrylic polymer (B) having glass transition temperature (Tg) such that Tg&#x2266;45&#xb0; C. and a mass average molecular weight (Mw) is such that 1500&#x2266;Mw&#x2266;4000.

Acrylic pressure-sensitive adhesive composition and acrylic pressure-sensitive adhesive tape

A multilayer circuit board is provided having an inner porous fluororesin layer containing electrical circuits, a ground conductor layer located adjacent the fluororesin layer on one side thereof and a power supply conductor layer located adjacent the fluororesin layer on the other side thereof, and a reinforcing, solid plastic dielectric layer adjacent each conductor layer and being external to the inner fluororesin layer. In an alternate embodiment, the multilayer circuit board may have a plurality of inner porous fluororesin layers, at least one fluororesin layer containing electrical circuits, and may have ground conductors and power supply conductors adjacent each fluororesin layer, and reinforcing, solid plastic dielectric layers on the outermost surfaces of the circuit board assembly. The ground and power supply conductor layers extend over the entire surfaces, respectively, of the inner fluororesin layers.

Multilayer circuit board

A printed circuit board is provided wherein a composite metal layer is affixed to at least one surface of a flexible dielectric substrate, the composite metal layer comprising an inner aluminum layer and an outer copper layer. Owing to the relatively high elongation of the aluminum layer, when the printed circuit board is flexed the circuit thereon does not crack.
