(A1) The Shore A hardness is in the range of 50 to 90. (A2) The copolymer gives a melting peak Tm in the range of 30 to 95° C., and the endothermic enthalpy ΔH corresponding to the melting peak is in the range of 1.0 to 20 J/g. (A3) The molecular weight distribution Mw/Mn is in the range of 1.2 to 3.0.

A method and an apparatus for bonding optical disk substrates, includes placing a pair of optical disk substrates on a stage while securing a height difference at an upper face of the stage loading the substrates between an upper face at a side of a center of the substrates and an upper face at a side of an outer circumference of the substrates. The method and the apparatus also includes photosetting the adhesive layer on the stage by irradiating a setting light to the substrate pair, thereby photosetting the adhesive layer and bonding the substrates.

A hetero-junction FET has an intermediate layer including n-type-impurity doped layer between an electron supply layer and an n-type cap layer. The intermediate layer cancels the polarized negative charge generated between the electron supply layer and the n-type cap layer by ionized positive charge, thereby reducing the barrier against the electrons and source/drain resistance.

A filter is disposed so as to cross at right angle to an airflow from an inside air inlet and an outside air inlet to an inlet port. The filter is made of a filter element formed in a corrugated shape by folding and is deformable so that a width of the filter in the axis direction of said rotary door could be shortened. Thus, it is possible to shorten the width of the filter in the axial direction of the rotary shaft by deforming the outer shape of the filter, therefore, the filter is easily taken out from the inside air inlet. Furthermore, since the filter can be taken out from the inside air inlet, the filter can be attached or detached without disassembling the inside and outside air switching case and casing for a blower fan, the working efficiency for cleaning and changing the filter being thereby improved.

Propylene-based polymers (A) are provided which, when used as pressure-sensitive adhesives to various adherends, show a desired initial adhesion and will not contaminate the adherends and which have excellent pellet handling properties. Pellets of the invention contain the propylene-based polymers (A). Pressure-sensitive adhesives of the invention contain the propylene-based polymers (A). The propylene-based polymer (A) includes 65 to 80 mol % of a structural unit derived from propylene, 5 to 10 mol % of a structural unit derived from ethylene and 15 to 25 mol % of a structural unit derived from a C4-20 α-olefin (wherein these percentages are calculated based on 100 mol % of the total of the structural unit derived from propylene, the structural unit derived from ethylene and the structural unit derived from a C4-20 α-olefin) and has a heat of crystal fusion of 5 to 45 (J/g) as measured by DSC. Compositions of the invention contain the propylene-based polymers (A).
摘要:
An optical switch section that switches the path of an optical packet transmitted thereto and outputs the optical packet, and a control section that generates multiple switch control signals in accordance with the destination of an optical packet transmitted thereto, transmits the multiple control signals to the optical switch section through multiple signal transmission lines and controls the ON/OFF states of multiple optical switches are included, and delay measuring means for measuring a difference in delay time among the multiple signal transmission lines is provided. In this case, the control section adjusts the transmission times of the multiple switch control signals such that the difference in delay time measured by the delay measuring means can be cancelled and that the multiple switch control signals transmitted through the multiple signal transmission lines can arrive at the multiple optical switches simultaneously and transmits the multiple switch control signals.

There is provided a magnesium alloy molded product being excellent in corrosion resistance. The magnesium alloy molded product being excellent in corrosion resistance and capable of being easily recycled is manufactured by forming an aluminum layer on a surface of a magnesium alloy molded body and then forming an anticorrosive film layer on the surface of the aluminum layer. In addition, a magnesium alloy molded product being excellent in corrosion resistance and having a brilliant anticorrosive structure is manufactured by forming a transparent anticorrosive film consisting of an organic acid amine salt on a cut surface of a magnesium alloy molded body and then forming a transparent painted film on the transparent anticorrosive film.

A plasma display panel includes a light-transmittable first substrate, a plurality of first electrodes provided in correspondence with pixels on the first substrate and partition walls provided on the first substrate so that each of the partition walls surrounds at least a part of one of the first electrodes. A Fluorescent layer is formed at a portion surrounded by the partition wall where the first electrode is located in such a manner that the first electrode surrounded by the partition wall is exposed by curing and baking a fluorescent ink having a photo-setting resin and an illuminant as its main ingredients. A light-transmittable second substrate is arranged in contact with the partition wall oppositely to the first substrate, and light-transmittable or opaque second electrodes are arranged on the second substrate oppositely to the first electrodes.
