A mobile phone includes a housing (7) formed by an upper housing part and a lower housing part that are integrally structured. At least a part of an upper surface of the housing (7) is made open to form an upper surface opening (11). Inside the housing (7), inner mounted components (a circuit board (8), a key switch board (9), or a battery) are mounted. The upper surface opening (11) of the housing (7) is covered with a key sheet (12). A method for assembling the mobile phone includes inserting the inner mounted components through the upper surface opening (11) into the inside of the housing (7) to be mounted inside the housing (7), and then covering the upper surface opening (11) with the key sheet (12).

A component tray system comprises a component tray having pockets, such as a standard JEDEC tray, and a thermoformed sheet removably attached to either a top or a bottom surface of the tray. The sheet includes thermoformed protrusions for altering at least the depth of the pockets. During manufacture of components, first components of a first size, such as bare substrates, are loaded into the pockets in the tray and held securely in place by the protrusions of the sheet. After a manufacturing operation, the first components are transformed into second components, larger than the first components. The sheet is removed so that these larger second components can be accommodated in the pockets. This arrangement provides that a single tray can be used throughout a manufacturing process, yet can be adapted to snugly accommodate components of varying sizes throughout.

A taped component includes a career tape having an upper surface having recesses provided therein, and products stored in the recesses, respectively. Each of the recesses has a bottom on which each of the products is placed. The bottom has an aperture provided therein, and the aperture faces a position different from the center of gravity of each of the products. This taped component allows the product to be mounted efficiently.

Provided are an embossed carrier tape having an embossed portion which is excellent in transparency and which has a high shape accuracy and a high buckling strength, and a method of production of the embossed carrier tape. The method of production of an embossed carrier tape comprises (a) a step of slitting a sheet which is obtained by biaxially stretching a styrene-based resin composition and which has an orientation relaxation stress of 0.2 to 0.8 MPa, measured in accordance with ASTM D-1504, into a tape-like form, (b) a step of heating only the reason of the slit tape where the embossed portion is to be formed, and (c) a step of forming an embossed portion in the heated area. Also, an embossed carrier tape manufactured by the method of production is provided.

A stackable holder for an IC package includes a base portion, a set of confining members that project from an upper surface of the base portion, and a set of abutting members that project from a lower surface of the base portion. The confining members have first ramp surfaces and cooperate to define a receiving space for confining the IC package. The abutting members have second ramp surfaces and are disposed to correspond in position to the confining members such that a projection of each second ramp surface onto a plane of the base portion overlaps a projection of a corresponding first ramp surface onto the plane of the base portion.

[Problems] Provided is a novel sheet for packaging electronic parts which is excellent in transparency and suitability for thickness reduction.[Means for solving Problems] The sheet for packaging electronic parts is one obtained by biaxially drawing a styrene resin composition comprising 7 to 99.5 mass % of a polystyrene resin (A), 0.5 to 3 mass % of a high-impact polystyrene resin (B) which has a rubber content of 4 to 10 mass %, and 0 to 92.5 mass % styrene-conjugated diene block copolymer (C) wherein the molecular weight of the styrene block part is at least 10,000 and less than 130,000. This sheet has a thickness of 0.1 to 0.7 mm and an orientation release stress value as measured in conformity with ASTM D-1504 of 0.2 to 0.8 MPa.

A carrier tape for storing components and for preventing nesting of successive wraps of the carrier tape when round onto a roll. In particular, the carrier tape comprises a strip like portion defining a top surface of the tape, and wall portions defining a plurality of substantially similarly shaped pockets spaced along the carrier tape and opening through the top surface. The wall portions of the substantially similarly shaped pockets include a bottom wall portion, a first wall portion extending from the bottom wall portion to the top surface of the carrier tape, a first cross-beam wall portion extending from the bottom wall portion and located between adjacent pockets on the carrier tape, and a second cross-beam wall portion extending from the bottom wall portion and located between selected adjacent pockets on the carrier tape. One or more of the cross-beam wall portions have a notched opening formed at a selected location along a length of the first or second cross-beam wall portions.

The invention provides carrier tapes in which, when the carrier tapes are wound up, regardless of the positions of accommodating portions of the upper and lower carrier tapes that overlap each other, electronic components accommodated in the accommodating portions can be reliably secured, so that the electronic components can be prevented from becoming dislodged from the accommodating portions; and electronic-component accommodating members including the carrier tapes.In each carrier tape having the plurality of accommodating portions that accommodate the electronic components and that are formed in a longitudinal direction, a plurality of protrusions are disposed at the bottom surfaces of the accommodating portions, and surfaces of interval portions provided between the accommodating portions that are adjacent to each other are formed lower than surfaces of guides of the carrier tapes.

The present invention concerns an adhesive film for releasably holding articles. In addition the present invention concerns a conveyor belt having such an adhesive film for transporting articles, wherein the articles are or can be releasably connected to the conveyor bell. In order to provide an adhesive film of low stretchability, high tearing strength and high tearing-propagation strength and of the lowest possible weight, to which articles to be transported can be temporarily stuck and with which said articles can be conveyed at high speed, it is proposed in accordance with the invention that the adhesive film has at least one carrier layer comprising a first polymer material which is stretchable by at most 50% at least in a direction X and an adhesive layer comprising a second, non-scalable polymer material which is more greatly stretchable than the carrier layer at least in the direction X.
