  • Publication number: 20220379789
    Abstract: An air pump device includes an electric pump unit including a pump mechanism and a motor configured to drive the pump mechanism, a case housing the electric pump unit, and a vibration-proof member interposed between the electric pump unit and the case. The vibration-proof member is a plate-shaped member made of an elastic resin material and is wound around the electric pump unit to wrap the electric pump unit therein. A part of the vibration-proof member is sandwiched between the electric pump unit and one of facing surfaces that are inner surfaces of the case and face each other inside the case. Another part of the vibration-proof member is sandwiched between the electric pump unit and the other one of the facing surfaces.

  • Publication number: 20220236832
    Abstract: A touch panel includes: first electrodes disposed in parallel at a position corresponding to a viewing area of a panel member and have a capacitance changing according to a proximity of an object to be detected; second electrodes that intersect with the first electrodes, are disposed in parallel, and similarly change in capacitance; third electrodes disposed in parallel between the first or second electrodes and have electrical resistances changing according to posture and temperature; and fourth electrodes extending along the respective third electrodes and similarly change in electrical resistance. A resistance change rate of the fourth electrodes due to temperature is the same as for the third electrodes. The resistance change rate of the fourth electrodes due to the posture change is 90% or less than for the third electrodes due to the posture change. This allows a pressing force to be accurately measured.
