摘要:
A pressure-sensitive adhesive tape includes a substrate layer, a colored layer, and a pressure-sensitive adhesive layer. The substrate layer is formed of a plastic material, such as polyethylene terephthalate. The colored layer is laminated on one major surface of the substrate layer. The colored layer is a black printed layer formed by printing, for example, black ink. The pressure-sensitive adhesive layer is laminated on the other major surface of the substrate layer. An acrylic polymer is preferably used as the pressure-sensitive adhesive layer. In the pressure-sensitive adhesive tape, a specular reflectance of visible light on the surface near to the colored layer is 2.0% or smaller.

The present invention provides a pressure-sensitive adhesive tape capable of exhibiting excellent adhesive property, and of inhibiting deformation of an adherend fixed with this pressure-sensitive adhesive tape, even under a high temperature or low temperature environment. The pressure-sensitive adhesive tape is one having a pressure-sensitive adhesive layer including a pressure-sensitive adhesive composition containing a (meth)acrylic polymer, wherein the (meth)acrylic polymer is obtained by copolymerization of a monomer mixture containing, at least, 60 to 96% by weight of a (meth)acrylic acid alkyl ester having an alkyl group with 4 to 12 carbon atoms, 2 to 10% by weight of a carboxyl group-containing monomer, and 2 to 8% by weight of an ethylenically unsaturated monomer having no carboxyl group, whose homopolymer has a glass transition temperature of 50 to 190° C. as monomer components, and the pressure-sensitive adhesive layer has a gel fraction of 0 to 30% by weight.

Embodiments of the invention are directed to setting optimum FIR filter coefficients. In one embodiment, a POR (Power On Reset) control block acquires temperature data from a thermistor. If the temperature is the first to have been detected as falling within a low temperature range, a filter coefficient determining block in a read/write channel determines filter coefficients of a FIR filter by using the signal acquired from the magnetic disk. The determined filter coefficients are set to the FIR filter. If the temperature data does not satisfy the above-mentioned condition, filter coefficients registered in a filter coefficient table are set to the FIR filter.

An image processing method at the time of character display in an image apparatus having a section for super-imposing character display on an ordinary dynamic picture image. In the method, the level of “color depth” of the dynamic picture image is automatically controlled at the time of character display to thereby make it easy to see character display. Specifically, when character display is effected in monochrome, the dynamic picture image is displayed in a color other than monochrome. When character display is effected in a color other than monochrome, the dynamic picture image is displayed in monochrome.

A tactile push button switch has a switch mechanism and a push button for driving the switch mechanism provided in a box-shaped switch case having a switch cover. The top of the push button protrudes upwardly of the switch cover through an opening made therein, and a drip-proof member made of sponge material is bonded to the top of the switch cover around the protruding push button.

A process of the preparation of the modified polyisocyanurate foams provided by a reaction of a polyisocyanate with a polyol composition mixture comprising a polyol, water, a trimerization catalyst, a carbodiimide catalyst, and an aromatic compound used as a chain extender. An amount of the aromatic compound used in the preparation is 0.5 to 10.0% by weight with respect to a total weight of the polyisocyanate and the polyol mixture.

A pressure-sensitive adhesive tape includes a substrate layer made of a plastic material, etc., and a pressure-sensitive adhesive layer provided on at least one of the surfaces of the substrate layer. The pressure sensitive adhesive tape has the thermal resistance at 80° C. of less than 2.00 [cm2*K/W] and the total thickness of the substrate layer and the pressure-sensitive adhesive layer of less than 10 μm. In addition, the pressure-sensitive adhesive layer may be provided on both surfaces of the substrate layer. The total thickness of the substrate layer and the pressure-sensitive adhesive layer may be less than 6 μm.

There is provided a pressure-sensitive adhesive tape that can exhibit good adhesion property and prevent display unevenness, which would otherwise be caused by deformation of the adherend fixed with it, even when exposed to environmental changes such as increases and decreases in temperature. The pressure-sensitive adhesive tape includes a pressure-sensitive adhesive layer comprising a pressure-sensitive adhesive composition containing a (meth)acryl-based polymer that comprises a monomer component of at least an alkyl (meth)acrylate ester having an alkyl group of 4 to 12 carbon atoms, wherein the pressure-sensitive adhesive composition contains 100 parts by weight of the (meth)acryl-based polymer and 5 to 50 parts by weight of a rosin resin, and the pressure-sensitive adhesive layer has a stress-strain curve with a maximum stress of 1.2 to 3.5 N/mm2 and a maximum elongation of 700 to 1,300% at 0° C.
