Even when a substrate on which a semiconductor package has been mounted is made curved, stress upon electrical connections is mitigated, thereby eliminating faulty connections and improving connection reliability. A semiconductor chip has electrodes on a second face thereof. Support blocks, capable of bending and flexing, are placed at two locations on a peripheral edge of a first face of the semiconductor chip. An interposer is placed so as to span the support blocks with the support blocks interposed between itself and the semiconductor chip, and has a wiring pattern in a flexible resin film. Two end portions of the interposer are folded back onto the side of the second face of the semiconductor chip, and the wiring pattern thereof is electrically connected to the electrodes of the semiconductor chip.

An object of the present invention is to enhance the inhalation efficiency by bearing liquid droplets on an air flow at the early stage of inhalation in an inhaler that is used for the user to inhale a medicine ejected from an ejection head. According to one embodiment of the present invention, from an operation in which the user lets out a breath before the start of inhalation, that is, from the exhalation stage, a positive pressure B produced by the exhalation is detected by a pressure detecting unit, and is compared with a standard pattern stored in a storage unit, by which the exhalation profile of the user is prepared. A time difference t between the exhalation finish time and the start time of next inhalation is estimated, followed by the determination of the ejection start time T1 based on these pieces of information.

In a charging device, a driving power supply circuit for driving a control circuit is formed as a separate system from a first power supply circuit, regardless of whether the first power supply circuit is in a driving state or a non-driving state. A microcomputer alternately and intermittently controls the first power supply circuit in the driving state or the non-driving state when the battery pack is not mounted in the charging device in order to reduce the potential difference between the battery pack and the output voltage of the first power supply circuit, thereby avoiding an excessive discharge current from the battery pack when the battery pack is mounted in the charging device.
