    • In an impedance matching device, a storage unit stores a control value representing a load value and a value equivalent to input impedance in advance. The control value identifies inductance and capacitance values matching a predetermined impedance value by use of either a first or second matching circuit. An impedance estimation unit estimates input impedance of the power transmission antenna. The load value estimation unit estimates load value of a circuit connected to a power reception antenna and consuming transmitted electric power. A circuit selection unit electrically connects the first matching circuit, the second matching circuit, or a through circuit per the load value and the input impedance equivalent value. A control value output unit reads out the control value stored in the storage unit based on the load value and the input impedance equivalent value, and outputs the control value to the circuit selected by the circuit selection unit.
    • 在阻抗匹配装置中,存储单元预先存储表示负载值和等于输入阻抗的值的控制值。 控制值通过使用第一或第二匹配电路来识别与预定阻抗值匹配的电感和电容值。 阻抗估计单元估计输电天线的输入阻抗。 负载值估计单元估计连接到受电天线的电路的负载值并消耗发送电力。 电路选择单元根据负载值和输入阻抗等效值将第一匹配电路,第二匹配电路或贯通电路电连接。 控制值输出单元基于负载值和输入阻抗等效值读出存储在存储单元中的控制值,并将控制值输出到由电路选择单元选择的电路。

    • A boat propulsion unit has a construction that prevents a structure near a drive shaft from becoming complicated and increased in size. The boat propulsion unit preferably in the form of an outboard motor includes a front propeller that is rotated together with a front propeller drive shaft during both forward travel and reverse travel of the boat, a rear propeller that is rotated together with a rear propeller drive shaft in an opposite direction of the front propeller during both of the forward travel and the reverse travel of the boat, and a forward-reverse drive that is arranged on an axis of the front propeller drive shaft and the rear propeller drive shaft, and that can be switched between a direction in which the front propeller drive shaft and the rear propeller drive shaft are rotated during the forward travel of the boat and a direction in which the front propeller drive shaft and the rear propeller drive shaft are rotated during the reverse travel of the boat.

    • Disclosed are a semiconductor device, a method for manufacturing the same, and a method for mounting the same. The method for manufacturing a semiconductor device includes the steps of: preparing a package film having a planar configuration whose region is divided into a device-mounting film portion having a device hole forming therein, an external-connection film portion, and a bent portion located between the device-mounting film portion and the external-connection film portion, an external electrode pad being formed on the external-connection film portion on a first surface side of the package film, an inner lead being formed in such a manner as to lead from the device hole to the external electrode pad via the bending portion; mounting a semiconductor chip on the device-mounting film portion on the first surface side by bonding the inner lead to an electrode pad of the semiconductor chip in a region where the device hole is formed; and bending the external-connection film portion at the bending portion 180° toward a second surface side of the package film and fixing the same. The method for mounting a semiconductor device on a mother board in close contact therewith includes the steps of: depositing solder balls on electrode pads of the mother board; and placing the semiconductor device on the mother board and melting the solder balls so as to electrically connect the electrode pads of the mother board and the external electrode pads of the semiconductor device.
