Publication number: 20240067158Abstract: A vehicle including an internal combustion engine and an automatic transmission capable of transmitting and receiving torque to and from an output shaft of the internal combustion engine is controlled. During operation of the internal combustion engine, a process that calculates a diluted water amount based on an operation state of the internal combustion engine is executed. The diluted water amount is the amount of water contained in lubricating oil in the internal combustion engine. Further, a process that controls the automatic transmission such that torque per unit period in the internal combustion engine becomes smaller when the diluted water amount is relatively large compared to when the diluted water amount is relatively small, while continuing the operation of the internal combustion engine, is executed.Type: ApplicationFiled: August 16, 2023Publication date: February 29, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Atsushi TABATA, Koichi OKUDA, Masato NAKANO, Nobuhiko SATAKE, Yoshito SEKIGUCHI

Patent number: 9386085Abstract: A method for managing an application delivery controller (ADC) cluster operable in a software defined networking (SDN)-based network and including a plurality of ADC virtual appliances (VAs). The method comprises creating, by a central controller, a hash table including a plurality of buckets allocated to active VAs out of the plurality of VAs, each bucket is assigned to a range of a source internet protocol (IP) addresses of a client; and programming by the central controller at least one ingress network element connected to the ADC cluster and receive incoming traffic from clients to perform a balanced incoming traffic distribution among the plurality of VAs, wherein the traffic distribution is based in part on the allocation of the buckets to the plurality of VAs and the SIP addresses of the clients originating the incoming traffic. The plurality of VAs are virtual ADC instances operable i the plurality of physical devices.Type: GrantFiled: April 4, 2013Date of Patent: July 5, 2016Assignee: Radware, Ltd.Inventors: Ehud Doron, Masato Sekiguchi

Patent number: 6468654Abstract: A treating agent comprises a nitrile group-containing highly saturated polymer rubber latex (A) having an iodine value of 120 or less, a rubber latex (B) other than the highly saturated polymer rubber latex, and a water-soluble resorcinol/formaldehyde condensate in amounts of 15 to 80%, 5 to 70% and 2 to 15%, all by weight in terms of solids, respectively. A rubber-reinforcing fiber product is coated with the treating agent. A rubber article such as a toothed belt, a tire and the like is made using this rubber-reinforcing fiber product. The glass fiber product coated with the treating agent may be further coated with a halogen-containing polymer-based adhesive as a secondary treating agent. Thus, the treating agent exhibits a large bonding force between the reinforcing fiber product and a matrix. Even if the rubber article is repeatedly subjected to a flexing stress, the strength thereof cannot be reduced. A peel-off cannot occurs between the reinforcing fiber product and the rubber matrix.Type: GrantFiled: August 13, 1998Date of Patent: October 22, 2002Assignee: Nippon Glass Fiber Co., Ltd.Inventors: Akira Okamura, Masato Sekiguchi
