The present invention belongs to a technical field for manufacturing a three-dimensional structure for an electronic device such as a radio wave shielding member through extension working of a metal plate having cuts. In conventional three-dimensional working of a metal plate, there is a problem in that a non-extension portion is wrinkled depending on extension of a cut. In the present invention, a connecting portion (3) extended in a second direction (D2) is provided at an equal pitch (p) in a first direction (D1) through an opening (4) having a rectangular cross-section in an intermediate portion (PB) between a cut forming portion (PC) having cuts (2) provided like a zigzag in the first direction (D1) and a non-extension portion (PA) having no cut in a metal plate (1). Consequently, even if the cut forming portion (PC) is extended, the connecting portion (3) is simply squashed and contracted and a boundary line (BL) portion is not deformed.

A biodegradable resin bottle having a container wall (1) including a biodegradable resin and having a vacuum-evaporated film (3) formed on the inner surface of the container wall (1) by a plasma CVD method. The vacuum-evaporated film (3) includes a first hydrocarbon vacuum-evaporated layer (3a) positioned on the inner surface of the container wall and a second hydrocarbon vacuum-evaporated layer (3b) formed on the above hydrocarbon vacuum-evaporated layer (3a). The first hydrocarbon vacuum-evaporated layer (3a) has polar groups introduced therein. The second hydrocarbon vacuum-evaporated layer (3b) exhibits hydrocarbon peaks stemming from CH, CH2 and CH3 in a region of wave numbers of 3200 to 2600 cm−1 as measured by FT-IR, has a CH2 ratio of not larger than 35% and a CH3 ratio of not smaller than 40% per the sum of CH, CH2 and CH3 calculated from the hydrocarbon peaks, and has no polar group introduced therein.

According to one embodiment, a wireless receiving apparatus includes a calculation module, a first determination module and a second determination module. The second determination module determines a length of interleaver blocks by determining whether or not a maximum value of second correlation value sequence is not less than a second threshold value within a first period, the second correlation value sequence being generated by combining third correlation values being between the receiving signal and each of reference signals, and to determine an initial position of the interleaver blocks based on a position of the maximum value.
