Patent number: 7592561Abstract: An illuminated switch includes an operation knob that includes an operation surface, a light source that emits light beams using a predetermined direction as an optical axis, and a first light guide member that is provided in the operation knob and guides the light beams emitted from the light source to the operation surface. The first light guide member includes a light incident surface formed of inclined surface that refracts light beams entering along the optical axis in a first direction, a reflection surface that reflects light beams refracted at the light incident surface in a second direction different from the first direction, and a light exit surface that transmits light beams reflected by the reflection surface.Type: GrantFiled: May 9, 2008Date of Patent: September 22, 2009Assignee: Alps Electric Co., Ltd.Inventors: Yoshinori Nishiyama, Ayumu Kobayashi

Patent number: 7500774Abstract: An annular light guide is provided. The annular light guide is made of optically transparent material, and is provided with an annular body that is an integrated combination of a light inlet and a light outlet. A light source is disposed in a cavity formed in the light inlet. Illumination light is emitted from the front surface 16c of the light outlet.Type: GrantFiled: June 15, 2006Date of Patent: March 10, 2009Assignee: Alps Electric Co., Ltd.Inventors: Yoshinori Nishiyama, Ayumu Kobayashi

Publication number: 20070159846Abstract: A surface emitting device is provided. The surface emitting device includes a light guide and a light source. The light guide includes a circular portion that curves light, and a light entrance portion that protrudes from the outer peripheral surface of the circular portion. The light source emits light toward the light entrance portion. The light source is disposed in a hollow formed in the center of the light entrance portion. The outer wall surface of the light entrance portion has a reflecting portion. The reflecting portion includes first and second reflecting surfaces that adjoin at an obtuse angle. Light of the light source heading from the inner wall surface to the outer wall surface of the light entrance portion is reflected by the reflecting portion so as to head into the circular portion.Type: ApplicationFiled: December 28, 2006Publication date: July 12, 2007Applicant: ALPS ELECTRIC CO., LTD.Inventors: Yoshinori Nishiyama, Ayumu Kobayashi

Patent number: 5010493Abstract: A load distribution method in which loads are divided into groups and each of a plurality of input pins of integrated circuits of a load is wired continuously with one stroke of a signal transmission line in a sequence from a driving output pin in each group when the wiring for distributing the drive signal from the driving output pin of an integrated circuit to plural input pins of integrated circuits, functioning as a load, is such that a plurality of intergrated circuits are mounted at given positions on a printed circuit board. In the load distribution method, the load is divided into groups by equally distributing a number of the loads so as to allow load capacities to be equal to each other on each of a plurality of signal transmission lines, and there is computed a signal propagation delay time of the signal transmission line wired equally in a distance to a load which is equal in a wiring sequence from the driving output pin in each group.Type: GrantFiled: April 26, 1989Date of Patent: April 23, 1991Assignees: Hitachi, Ltd., Hitachi Computer Engineering Co., Ltd.Inventors: Kenji Matsumoto, Tomoatsu Yanagita, Yoshinori Nishiyama, Masahiko Nagai, Mitsuru Morikuni
