Patent number: 7147325Abstract: It is an object of the invention to ensure in a series of contact lenses composed of an assorted plurality of contact lenses having mutually different optical characteristics such as refractive power or the like that each contact lens is capable of exhibiting advantageously and consistently a good wear comfort and tear fluid exchange. In order to attain the object, the present invention arranges each contact lens 10a, 10b, 10c making up the series contact lens designed and having mutually different optical characteristics in the optical zone, such that not only is a shape of the lens back surface 14 of the optical zone 28 identified, but a shape of the peripheral zone 30 is identified at least the outer peripheral zone 44 that contributes to wear comfort and tear fluid exchange.Type: GrantFiled: March 25, 2003Date of Patent: December 12, 2006Assignee: Menicon Co., Ltd.Inventors: Yuuji Gotou, Kunio Maruyama

Patent number: 6610350Abstract: A method of modifying a surface of an ophthalmic lens, includes the steps of: generating plasma at an atmospheric pressure between electrodes of a plasma generating device; and blowing the plasma from the plasma generating device by introducing a gas between the electrodes. The ophthalmic lens, which is located outside the plasma generating device, is irradiated with the plasma blown out from the plasma generating device to modify the surface of the ophthalmic lens to form a final ophthalmic lens product.Type: GrantFiled: October 1, 2001Date of Patent: August 26, 2003Assignee: Menicon Co., Ltd.Inventors: Hiroaki Suzuki, Yuuji Gotou, Kazuhiko Nakada

Patent number: 6491281Abstract: A mold assembly for forming an ophthalmic lens article includes a first mold and a second mold. The first and second molds are assembled together to define a mold cavity therebetween having a profile corresponding to that of the ophthalmic lens article to be formed. The mold cavity is filled with a polymeric material which is polymerized to form the ophthalmic lens article. At least one of the first and second molds is a resin mold which is formed from a resin material, and a portion of at least a molding surface of the resin mold is directly irradiated with UV radiation so as to provide a UV-treated surface. The ophthalmic lens article formed in the mold cavity is held on the resin mold such that the ophthalmic lens article adheres to the UV-treated surface upon separating the first and second molds away from one another.Type: GrantFiled: August 24, 2000Date of Patent: December 10, 2002Assignee: Menicon Co., Ltd.Inventors: Yuuji Gotou, Yasushi Matsuda

Patent number: 6296593Abstract: A generator (4) is combined with drive wheels (8) of a vehicle, and the output of an engine (2) is transmitted to the drive wheels (8) under an engaging force of an electromagnetic clutch (3) in response to an energizing current. During a predetermined deceleration state, a braking force is applied to the drive wheels (8) and a battery (15) is charged by the generator (4) which performs regenerative power generation. At this time, the controller (16) supplies a weak energizing current to the electromagnetic clutch (3) so as to put the clutch (3) into a partially engaged state. A sensor (29) detects the output rotation speed of the clutch (3). When the output rotation speed of the clutch (3) is high, the controller (16) decreases the energizing current so that the rotational resistance of the electromagnetic clutch (3) is reduced.Type: GrantFiled: October 25, 1999Date of Patent: October 2, 2001Assignee: Nissan Motor Co., Ltd.Inventors: Yuuji Gotou, Noboru Hattori
