Abstract: A face mask system for effectively dispensing a medication and/or scented material to a user. The face mask system generally includes a face mask with a medication and/or scented material that is dispensed to a wearer of the face mask via the air breathed into the respiratory system. The medication is dispensed via a medicated cover that is removably attached to the face mask. Alternatively, medicated strips are attached to the face mask to dispense the medication to the wearer of the face mask. One or more deflectors are attached to an upper portion of the face mask to deflect the medication from contacting the eyes of the wearer when worn at daytime.

Abstract: A semiconductor device of the present invention includes a semiconductor element having an upper surface and a lower surface, a metal plate thermally connected to the lower surface, an upper surface electrode soldered to the upper surface, an insulating sheet formed on the upper surface electrode so as to be in surface contact with the upper surface electrode, a shielding plate formed on the insulating sheet so as to be in surface contact with the insulating sheet, the shielding plate shielding against radiation noise, and a resin with which the semiconductor element is covered, while a portion of the upper surface electrode, a portion of the shielding plate and a lower surface of the metal plate are exposed to the outside, wherein the heat conductivity of the insulating sheet is higher than the heat conductivity of the resin.

Abstract: An object of the present invention is to achieve reductions in size and costs of a vehicle-mounted motor driving control board in a configuration which allows the redundancy of a power supply to be ensured. The vehicle-mounted motor driving control board is formed by one printed circuit board on which are formed two inverter driving circuits for driving two inverter circuits for three-phase motors, and a voltage step-up/step-down driving circuit for driving a voltage step-up/step-down circuit for supplying electric power to the inverter circuits. The vehicle-mounted motor driving control board further includes a first power supply circuit for supplying electric power to part of constituent circuits constituting the voltage step-up/step-down driving circuit and the two inverter driving circuits, and a second power supply circuit for supplying electric power to the remainder of the constituent circuits in the voltage step-up/step-down driving circuit and the two inverter driving circuits.
