  • Patent number: 10071490
    Abstract: Electric shaver includes body, head having blade block, and head supporting part connecting body with head. Head supporting part includes swing supporting part supporting head swingably about two swing axes, and head float part so that head is movable up and down with respect to body. This configuration allows head to swing about the two axes, and thus head easily follows undulations of skin. Head is movable up and down with respect to body, and thus head sinks with respect to body when head is strongly pressed against the skin. The aspect provides electric shaver that has a high follow-up performance of head swinging according to undulations of skin and hardly irritates the skin strongly.

  • Patent number: 9962842
    Abstract: This slit blade block includes multiple comb teeth adjacent to multiple outer blade pieces. Each comb tooth has a leading end surface, and a protruding part protruding in a direction away from the outer blade pieces. The protruding parts include an apical part that is the outermost end in said direction away from the outer blade pieces. The leading end surfaces of the protruding parts are positioned between the leading end surfaces and the base end surfaces of the adjacent outer blade pieces. Length L1 in the height direction, defined by the apical part of the protruding parts and the leading end surfaces of the protruding parts, is less than or equal to thickness L2 of the outer blade pieces, defined by the leading end surface and the base end surface of the outer blade pieces.

  • Patent number: 8547119
    Abstract: A dynamic quantity detection device includes a detection portion, a signal process portion, and an operation mode switch portion. The detection portion detects a dynamic quantity applied from an outside and generates a sensor signal in accordance with the dynamic quantity. The signal process portion processes the sensor signal from the detection portion to have a property suitable for an external device. When the sensor signal output from the detection portion is less than or equal to a predetermined threshold value, the operation mode switch portion sets an operation mode to a power save mode by stopping an operation of the signal process portion. When the sensor signal output from the detection portion is greater than the predetermined threshold value, the operation mode switch portion switches the operation mode to a normal mode by activating the signal process portion.
