Title: Semiconductor switch
Inventor: NISHIKAWA HIDEO
IPC: H03K17/13
Filed: 2011-11-16
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor switch capable of increasing energy efficiency.SOLUTION: A semiconductor switch 1 drives an LED 2 by a driving circuit 3 to cause the LED 2 to emit light. The light emitted from the LED 2 is received by a light-receiving unit 4. The driving circuit 3 includes a bipolar transistor 31, a coil 32, and a diode 33 and the like. The bipolar transistor 31 is switched to a conductive state and a non-conductive state. When the bipolar transistor 31 is in the conductive state, current is supplied from a power supply to the LED 2. When the bipolar transistor 31 is in the non-conductive state, current is not supplied from the power supply to the LED 2. The coil 32 is connected in series to the LED 2. When the bipolar transistor 31 switches from the conductive state to the non-conductive state, the coil 32 produces an induced electromotive force due to a self-induced action. The diode 33 is connected in parallel to the LED 2 and the coil 32. When the bipolar transistor 31 is in the non-conductive state, the diode 33 recycles current to the LED 2 by the induced electromotive force produced by the coil 32.

Title: Earhole attachment-type sound pickup device, signal processing device, and sound pickup method
Inventor: ASADA KOHEI
IPC: H04R3/00
Filed: 2011-12-08
Abstract: PROBLEM TO BE SOLVED: To achieve high-S/N-ratio voice pickup in which influence of noise is reduced without using noise reduction processing.SOLUTION: As an earhole attachment-type sound pickup device, a microphone that picks up spoken voice is provided in a space that is substantially hermetically sealed from the outside and that is in communication with the external auditory meatus of a wearer (speaker). By being provided in a space hermetically sealed from the outside, influence of noise can be effectively reduced. In addition, because the device picks up spoken voice propagated via the external auditory meatus of the speaker, the spoken voice can be picked up with a higher S/N ratio than that with a conventional earphone microphone which picks up voice spoken by a wearer and propagated via an external environment. Here, because spoken voice components predominate over noise components, particularly at low frequencies, in a sound pickup signal acquired via the external auditory meatus, the S/N ratio of the spoken-voice sound pickup signal is further improved by extracting the low-frequency components in the sound pickup signal by using, for example, an LPF and the like. Alternatively, sound quality can be improved by subjecting the sound pickup signal to an equalizing process for reducing muffled noise generated at the time of picking up sound via the external auditory meatus.
