  • Publication number: 20050199096
    Abstract: A method for manufacturing an inner cutter for a reciprocating electric shaver, including the steps of: forming a plurality of slits in a thin plate; forming ribs by pressing bridging-portions that remain between the slits so that each rib extends for the length of each bridging-portion and forms a protruding portion that protrudes in the width direction, thus obtaining an intermediate worked member; deep drawing the intermediate worked member that has the ribs into substantially an arch shape with the protruding portions of the ribs facing outward; and grinding the outer surface of the arch-form intermediate worked member, thus forming cutting edges which have blade surfaces and acute rake angles in the protruding portions.

  • Publication number: 20050183267
    Abstract: An electric shaver in which a plurality of mutually separated cutter blades provided in an inner cutter are moved in relative terms while making sliding contact with an outer cutter that is formed with a plurality of hair introduction openings, so that hair that enters into the hair introduction openings of the outer cutter is cut by the cutter blades, wherein the cutter blades are caused to intersect the same hair introduction openings of the outer cutter at different angles.

  • Publication number: 20050155230
    Abstract: A method for manufacturing an inner cutter for a reciprocating electric shaver, including the steps of: press-stamping a thin metal plate to obtain a thin metal plate element that has an outer contour of an unfolded inner cutter and elongated openings that extend substantially perpendicular to the direction of the reciprocating motion the inner cutter makes and further has bridging-portions formed between the elongated openings; pressing the bridging-portions so that each bridging-portion has a final sectional shape of each cutter blade of the inner cutter; twisting the bridging-portions so that the cutter surfaces of the cutter blades are aligned substantially to the surface of the thin metal plate element; forming the thin metal plate element into substantially an arch shape with the cutter surface sides of the cutter blades facing outward; and executing finishing-work on the outer circumferential surface of the arch-shaped thin metal plate element.

  • Publication number: 20050120567
    Abstract: An electric rotary shaver including a substantially circular disk form outer cutter, which has hair entry openings, and an inner cutter, which rotates while making sliding contact with the inner surface of the outer cutter; and the inner cutter including an inner cutter base, which is made of a synthetic resin and comprised of a boss that engages with a rotary shaft of the shaver and cutter blade supports that extend radially outward from the boss, and a plurality of cutter blade sections, which have a cutter blade and are installed on the cutter blade supports. The cutter blade sections can be formed in a shape of a ring to make a cutter blade ring so that the cutter blade ring is disposed on the cutter blade supports.

  • Publication number: 20040078978
    Abstract: An electric shaver including an outer cutter, which has a ring-shaped shaving surface that contacts the skin and an outer cutter surface that is formed on its inside surface, and an inner cutter, which has an inner cutter surface that makes sliding contact with the outer cutter surface, the outer and inner cutters being tiltably disposed with respect to a cutter frame disposed on a head portion of the shaver main body; wherein the inner cutter surface has a convex shape, the outer cutter surface has a concave shape that receives therein the convex inner cutter surface, and the convex inner cutter surface of the inner cutter is engaged with the concave outer cutter surface, thus preventing axial deviation of the inner cutter during the rotation.

  • Patent number: 5891413
    Abstract: A method of continuously producing a carbide from a moisture-containing organic substance allows for the recycling of the organic substance, which is conventionally thrown away waste. The method includes a dewatering process for removing water from the moisture containing material. A moisture adjustment process removes more water from a dewatered cake. A carbonization process continuously carbonizes the moisture adjusted material. During the moisture adjustment process, a carbide produced during the carbonization process is mixed in the dewatered cake to remove the moisture therefrom.

  • Patent number: 5427001
    Abstract: Method and apparatus for opening slits of uneven lengths in the concentric circular shaving sections of an external cutting member that is used in an electric razor using a rotary cutter that cuts the shaving sections of the external cutting member in radial directions as the external cutting member is rotated around its axis by a predetermined angle with a use of an index device. The differences in the length of the slit are obtained by changing the cutting angle of the rotary cutter relative to the external cutting member.

  • Patent number: 5394611
    Abstract: An electric razor with a fan assembly installed under and coaxially with a rotary inner cutter. The whiskers entering through slits of an outer cutter are cut by the inner and outer cutters, and the sheared whiskers are blown by the fans of the fan assembly and collected in a receptacle element provided in the razor. Thus, the shaving debris does not stick to the inner and outer cutters, making it easy to clean the razor.

  • Patent number: 5390416
    Abstract: An electric razor including a plurality of external and internal cutting members in which each external cutting member has slits and a plurality of concentric tracks formed in the back and each internal cutting member has a plurality of rows of cutting edges that can rotate in the concentric tracks of the external cutting member. The slits are formed so that imaginary lines extending towards the center of the internal cutting member do not intersect the center of the internal cutting member, and the cutting edges are at the ends of the arms that extend outwardly from the internal cutting member.

  • Patent number: 5329702
    Abstract: An electric razor with round external cutting members and round internal cutting members with cutters at the end of uneven length arms. Each one of the external cutting members has concentric circular shaving sections obtained by concentric grooves, and the backs of the circular shaving sections are defined as tracks so that cutters of the internal cutting member are rotated in the tracks. The external cutting member is formed with slits which are substantially in a radial direction and uneven in the length.
