Publication number: 20110211368Abstract: A light guide plate has a substantially flat shape and used as a backlight for an electronic appliance. The light guide plate introduces thereinto illuminating light emitted from a light source through part of a side surface thereof and directs the illuminating light out of the light guide plate through light emitting parts formed in a main surface of the light guide plate, in which a light-receiving surface for the illuminating light on the side surface is inclined relative to a plane perpendicular to the main surface. Thus, illuminating light is refracted, enters the light guide plate, and propagates in the light guide plate while undergoing total internal reflection. Light can be effectively directed out of the light guide plate through the light emitting parts.Type: ApplicationFiled: October 8, 2009Publication date: September 1, 2011Inventor: Hidehiko Mishima

Patent number: 5320000Abstract: A particular shift control system is provided for an automatic transmission having a primary transmission, changeable to at least three primary gear ratios, and a secondary transmission, changeable to at least two secondary gear ratios. The primary and secondary transmissions combine to shift the automatic transmission to a plurality of forward speeds. The control system monitors the progression of change in the primary transmission gear ratio. In a specific automotive drive condition, the primary transmission changes from one primary gear ratio to another primary gear ratio via an intermediate primary gear ratio between the two primary gear ratios. This produces an increase or decrease in a primary gear ratio. At the same time, the secondary transmission decreases or increases, respectively, a secondary gear ratio so as to shift the automatic transmission from one forward speed to another, skipping an intermediate speed between the two forward speeds.Type: GrantFiled: September 23, 1992Date of Patent: June 14, 1994Assignee: Mazda Motor CorporationInventors: Toshihisa Marusue, Hidehiko Mishima

Patent number: 5267491Abstract: The control system for an automatic transmission shifts the main transmission simultaneously with the auxiliary transmission at the time of a particular shift. At this time, a target gear ratio progress value of the auxiliary transmission is set for a gear ratio progress value indicative of a shift progress state of the main transmission. The main transmission is arranged so as to finish the shift control within a given target period of time, and the auxiliary transmission is arranged to implement the shift control by the feedback control so as to follow the target gear ratio progress value. The shift control of the auxiliary transmission is corrected by the learning control on the basis of a deviation between the target gear ratio progress value and the actual gear ratio progress value.Type: GrantFiled: December 28, 1992Date of Patent: December 7, 1993Assignee: Mazda Motor CorporationInventors: Takayuki Sumimoto, Minoru Kuriyama, Kazunori Enokido, Hidehiko Mishima, Tatsutoshi Miyabe, Toshihisa Marusue

Patent number: 5088357Abstract: A hydraulic control system shifts an automatic transmission into at least a reverse range and a drive range having several forward speed gears by selectively coupling a plurality of frictional coupling elements, including a reverse coupling element. The control system includes a throttle, such as an orifice, for regulating hydraulic pressure applied to the reverse coupling element. A bypass circuit is provided in the control system for applying the hydraulic pressure, bypassing the throttle, to the reverse coupling element. The bypass circuit is opened when a specific operating condition of the automatic transmission of an engine is created, so as to apply the hydraulic pressure through the bypass circuit to the reverse coupling element to rapidly achieve a coupling of the reverse coupling element.Type: GrantFiled: January 25, 1991Date of Patent: February 18, 1992Assignee: Mazda Motor CorporationInventors: Shinya Kamada, Hidehiko Mishima
