Abstract: An electronic device includes an upper package including an upper chip, a lower package including a lower chip, a printed circuit board above which the upper package and the lower package are laminated, solder balls connecting the upper package and the lower package, solder balls connecting the lower package and the printed circuit board. The lower package has a thermal expansion coefficient set between a thermal expansion coefficient of the upper package and a thermal expansion coefficient of the printed circuit board.

Abstract: A receiving apparatus for receiving a digital television broadcast includes an amplification unit that amplifies radio frequency signals supplied from an antenna at a predetermined gain to output the amplified radio frequency signals, a channel selection unit that selects a broadcast wave from the radio frequency signals output from the amplification unit to produce output signals, a demodulation unit that processes the output signals to demodulate content data transmitted on the broadcast wave, and a control unit that controls the gain of the amplification unit so that the signal level of the output signals becomes a predetermined value. The control unit controls the gain of the amplification unit using the control start value and changes the control start value in accordance with the result of processing by the demodulation unit.

Abstract: A moving apparatus with a driving force assist mechanism traveled mainly by human power. This moving apparatus detects, in a non-contact manner, with respect to rotating portion such as traveling wheel, etc., rotation speed of the rotating portion to detect traveling state to deliver, from the driving force assist mechanism, assistant driving force corresponding to speed change information that a person who operates the moving apparatus intends to give on the basis of the detected traveling information to carry out traveling to thereby permit smooth traveling even in the case where traveling by only human power becomes difficult.
