Patent number: 6837192Abstract: An engine cooling system includes a flow control valve and an electronic control unit (ECU) for controlling the flow control valve. The flow control valve regulates the flow rate of coolant flowing through a radiator in a coolant circuit. The ECU feedback controls the opening size of the flow control valve such that the temperature of coolant at an engine outlet seeks a predetermined target value. During the feedback control, the ECU controls the flow control valve such that the opening size of the flow control valve remains above a predetermined lowest value. As a result, the flow control valve is prevented from falling in a small opening size range in which in which it is difficult to cause the engine outlet coolant temperature to seek the target value, and the engine outlet coolant temperature is favorably adjusted.Type: GrantFiled: September 3, 2002Date of Patent: January 4, 2005Assignees: Toyota Jidosha Kabushiki Kaisha, Aisan Kogyo Kabushiki KaishaInventors: Yoshikazu Shinpo, Isao Takagi, Shigetaka Yoshikawa, Hiromichi Murakami, Daisuke Yamamoto

Patent number: 6688262Abstract: An engine cooling system controls a cooling degree of an engine 1 according to an operating condition thereof by circulating cooling water through the engine. This system is provided with a water temperature sensor 31 for detecting a cooling water temperature THW1, a flow rate regulating valve 8 for regulating a circulation flow rate of the cooling water, and an electronic control unit (ECU) 30 for controlling the valve 8. The ECU 30 sets a non-control region and a first and second control regions, each centering on a target water temperature to be calculated according to operating conditions of the engine 1.Type: GrantFiled: June 10, 2002Date of Patent: February 10, 2004Assignees: Aisan Kogyo Kabushiki Kaisha, Toyota Jidosha Kabushiki KaishaInventors: Hiromichi Murakami, Daisuke Yamamoto, Shigetaka Yoshikawa, Yoshikazu Shinpo, Isao Takagi

Patent number: 6684826Abstract: An engine cooling apparatus includes a flow regulating valve, which adjusts a flow rate of a coolant passing through a radiator provided in a coolant circulation passage of the engine, and an electronic control unit (ECU), which controls an opening of the flow regulating valve such that an engine outlet coolant temperature reaches a necessary target temperature. The ECU sets a basic opening as a feedforward term based on the operation state of the engine. The ECU calculates a final opening from an F/B constant as a feedback term, which is increased or decreased such that the engine outlet coolant temperature reaches the target temperature, and the basic opening. Further, the ECU performs feedback control on the opening of the flow regulating valve based on the final opening. As a result, the responsibility of the coolant temperature control is improved.Type: GrantFiled: July 23, 2002Date of Patent: February 3, 2004Assignees: Toyota Jidosha Kabushiki Kaisha, Aisan Kogyo Kabushiki KaishaInventors: Shigetaka Yoshikawa, Yoshikazu Shinpo, Isao Takagi, Daisuke Yamamoto, Hiromichi Murakami

Patent number: 6679201Abstract: An engine cooling system controls a cooling degree of an engine 1 according to an operating condition thereof by circulating cooling water through the engine. This system is provided with a flow rate regulating valve 8 for regulating a circulation flow rate of the cooling water. An electronic control unit (ECU) 30 controls the valve 8 to open at a predetermined opening when determining the engine 1 as being stopped. In this opening control, the ECU 30 controls to bring a valve element into contact with a valve body once and then move the valve element to determine the predetermined opening with reference to a full-closed position of the valve element.Type: GrantFiled: May 17, 2002Date of Patent: January 20, 2004Assignees: Aisan Kogyo Kabushiki Kaisha, Toyota Jidosha Kabushiki KaishaInventors: Hiromichi Murakami, Daisuke Yamamoto, Hiroshi Suwahara

Patent number: 6666176Abstract: A flow control valve is located in a coolant circuit that extends through an engine. The flow control valve is operated in accordance with a control mode selected from a full closing control mode, a full opening control mode, and a feedback control mode. When switching from one control mode to another, the flow control valve is controlled in accordance with a transitional control procedure selected from different types of transitional control procedures. The transitional control procedure to be performed is selected depending on which control modes are performed before and after the control mode switching and/or the current condition of the engine. Transitional controlling of the flow control valve is thus appropriately conducted.Type: GrantFiled: July 23, 2002Date of Patent: December 23, 2003Assignees: Toyota Jidosha Kabushiki Kaisha, Aisan Kogyo Kabushiki KaishaInventors: Yoshikazu Shinpo, Shigetaka Yoshikawa, Isao Takagi, Daisuke Yamamoto, Hiromichi Murakami

Patent number: 5268769Abstract: An image signal decoding system for decoding a variable length image data compressed by a modified Huffman code. The decoding object data is cut by a fixed length of 13 bits and the cut data is decoded by using a decode-encode circuit for decoding the input of the modified Huffman code with its end portion equalized and for encoding and generating the code length, the code kind and the run-length number on the basis of the decoded contents, and by using a rotator for shifting the bit data. For decoding a code which immediately follows, the data is shifted with the rotator by the bit number of the code length of the decoding output result, the end portion of the next decoding output result, the end portion of the next decoding object data is equalized with the input end portion of the encode-decode circuit, and it is placed after the immediately following decoding object data and is then input into the decode-encode circuit and decoded.Type: GrantFiled: August 1, 1991Date of Patent: December 7, 1993Assignees: Hitachi, Ltd., Hitachi Information Network Ltd., Hitachi Computer Engineering Co., Ltd.Inventors: Tadashi Tsuchiya, Hiroo Fujisaki, Tomoya Nishi, Hiromichi Murakami

Patent number: 4943936Abstract: A print control apparatus includes a page memory and a format memory respectively for receiving and storing a plurality of page data items and a plurality of format data entries which are supplied from a host computer, and is adapted to expand the corresponding page data and format data stored in the memories into dot data to perform overlay operation to thereby output the print data to a printer. The format memory is divided into a plurality of blocks, and the in-use and unused states of each of the blocks are controlled by a control table. The format data is prefetched into blocks in a free state detected by the control table, to thereby prevent the printing operation from being interrupted in case of changing the format data.Type: GrantFiled: January 12, 1988Date of Patent: July 24, 1990Assignee: Hitachi, Ltd.Inventors: Kenshi Hirai, Hiromichi Murakami, Kikuo Hatazawa
