Patent number: 6510835Abstract: An engine can switch a combustion mode between homogeneous charge combustion and stratified charge combustion. The engine is controlled in accordance with a load acting on the engine. When homogeneous charge combustion is executed, an intake pressure, or a parameter representing the amount of intake air, is used as a value representing an engine load. When stratified charge combustion is executed, a value equivalent to the intake pressure presuming homogeneous charge combustion is executed with the amount of manipulation of an acceleration pedal at that time is computed as a virtual intake pressure, and the virtual intake pressure is used as a value representing the engine load. In either combustion mode, therefore, the intake pressure, or a common parameter, is used as a value representing the engine load to control the engine. This simplifies matching of engine power torques between both combustion modes.Type: GrantFiled: August 20, 2001Date of Patent: January 28, 2003Assignee: Toyota Jidosha Kabushiki KaishaInventors: Hiroyuki Mizuno, Noboru Takagi, Naohide Fuwa

Patent number: 6510872Abstract: A woven carpet backing may include monofilament warp yarns and alternating monofilament and multifilament fill yarns. The yarns may be woven using a weave, such as a non-traditional weave, that places all of the multifilament fill yarns on the face of the fabric and all of the monofilament fill yarns on the back of the fabric. Monofilament fill yarns and multifilament fill yarns are overstuffed, thereby creating a coverage factor greater than one hundred percent. The invention results in a carpet backing with the appearance of a primary carpet backing on one side of the fabric and the appearance of a secondary carpet backing on the opposite side of the fabric. The need for a secondary carpet backing is eliminated by the woven carpet backing.Type: GrantFiled: June 30, 2000Date of Patent: January 28, 2003Assignees: Wayn-Tex, Incorporated, Mohawk Carpet CorporationInventors: Kirk D.

Patent number: 6510879Abstract: A device of depth index of a planing machine includes a bottom base, an upper base, an index device and a sensor device. The upper base is fitted with an index device at a preset position in the front. A push rod is pushed up to activate the index device to show a planing depth. The sensor device includes a sensing strip pivotally connected to a preset position under the upper base. As soon as contacting with a wood material moving on the bottom base, the sensing strip will rotate for a preset angle and prop up the push rod to let it activate the index device to show a numerical value of planing depth. As the sensing strip is elongate, a wood material moving on the bottom base can immediately sensed by it, no matter what size or where or how it is placed, obtaining effect of wholly sensing the wood material being planed and ensuring measuring precision.Type: GrantFiled: October 19, 2001Date of Patent: January 28, 2003Inventor: Bor Yann Chuang
