Abstract: A mat for detecting biological information has an air bag formed in an elongated shape and outputting air according to pressure from a living body, a plate-shaped cushion member in which a concave portion having substantially the same size as the air bag is formed in a central portion, the air bag is fitted in the concave portion, and has substantially the same thickness as the air bag, and a pair of synthetic resin plate-shaped members each having substantially the same size as the plate-shaped cushion member and being formed so as to be bendable as a whole and provided so as to sandwich the plate-shaped cushion member.

Abstract: A radio frequency heating apparatus includes a printed circuit board on which power-supply noise filter circuit (20) that reduces power-supply noise generated by magnetron (15) and power-supply synchronization detecting circuit (21) that is connected across both terminals of power supply for detecting information on power-supply frequency are mounted. Power-supply synchronization detecting circuit (21) is used as a discharge path for charge accumulated at both ends of capacitor (3) configuring power-supply noise filter circuit (20). This achieves the radio frequency heating apparatus that eliminates the risk of electric shock, reduces power consumption, and reduces the number of components.

Abstract: An appliance comprises: an appliance main body for employing an AC power supply, and a power supply unit, which outputs a DC voltage and an AC voltage to the appliance main body as power supply voltages. The power supply unit comprises: a power supply circuit for converting the input AC into DC, which is insulated from the AC power supply; relays for turning ON and OFF a supply of the AC power supply voltage; and an earth leakage sensing circuit provided between contact points of the relays and the appliance main body, for turning OFF the relays while earth leakage is sensed. While the earth leakage occurs, the sensing circuit turns OFF the relays so as to stop the supply of the AC voltage. It is possible to avoid a failure caused by earth leakage in advance, and also, the relays are turned OFF during a standby mode.

Abstract: A purpose of the present invention is to avoid either earth leakage or an electric shock, and is to reduce power consumption during a standby mode. An electric appliance comprises: an appliance main body (1) for employing an AC power supply, and a power supply unit (6) to which the AC power supply provided in the appliance main body (1) is connected as an input power supply, which outputs a DC voltage and an AC voltage to the appliance main body (1) as power supply voltages.
