Abstract: According to one implementation, a molding equipment of a composite material includes a vessel, a decompression system and a heating medium supply system. The vessel houses a molding target sealed by a sealing object. The decompression system performs bending forming of the molding target and pressurization on the molding target after the bending forming by decompressing a region surrounded by the sealing object in the vessel. The heating medium supply system supplies a heating medium into the vessel. The heating medium is supplied for the bending forming, and heating and curing of the molding target under the pressurization.

Abstract: In a mobile phone device 1 including a three-axial direction vibration sensor 16 for detecting the walking of a user carrying the mobile phone device 1 and counting the number of walking steps, when an incoming call is received, vibrations due to a notification operation by a vibrator 14 or a speaker 15 are transmitted to the three-axial direction vibration sensor 16. As a result, the three-axial direction vibration sensor 16 inevitably detects unintended vibrations in addition to vibrations from walking, causing the number of walking steps to be miscounted. To prevent this and perform the accurate detection of walking, in the present invention, the detection of walking is performed without using, among vibrations in three directions detected by the three-axial direction vibration sensor 16, vibrations in the same direction as the direction of vibrations caused by a notification operation by the vibrator 14 or the speaker 15.

Abstract: There is provided a mask for use in printing solder on a plurality of terminals formed on a substrate so as to correspond to a plurality of terminals of an IC package. The mask has openings through which the solder is applied, and the openings are larger than the terminals. Although a wiring line adjacent to the terminals may be covered with the solder, a reflow process causes the solder to be divided into a first portion and a second portion, thus preventing short-circuits between the wiring line and the terminals.
