Patent number: 7207185Abstract: A vehicle air conditioning apparatus includes a refrigerant circulation circuit. The vehicle air conditioning apparatus has a variable displacement type compressor, a first pressure monitoring point, a second pressure monitoring point and an oil separator in the refrigerant circulation circuit. Also, the vehicle air conditioning apparatus has a control valve in the compressor. The compressor compresses refrigerant gas. Displacement of the compressor is variable. The refrigerant gas includes oil. The second pressure monitoring point is located more downstream than the first pressure monitoring point. The control valve controls the displacement based on differential pressure between the first and second pressure monitoring points. The oil separator is located between the first and second pressure monitoring points in order to separate the oil from the compressed refrigerant gas, thereby the oil separator serves as means for manifesting the differential pressure.Type: GrantFiled: December 16, 2003Date of Patent: April 24, 2007Assignee: General Electric CompanyInventors: Masaki Ota, Tomoji Tarutani, Hisato Kawamura, Yoshinori Inoue, Masahiro Kawaguchi

Publication number: 20070012057Abstract: A displacing device is incorporated in a displacement control valve. The displacing device includes a first pressure chamber, a second pressure chamber, a second bellows, a transmission rod, and an urging spring. The second pressure chamber communicates with a suction chamber. The interior of the second pressure chamber is a suction pressure zone. When the pressure in the suction pressure zone is less than or equal to a predetermined reference pressure, the transmission rod moves an actuation rod (valve body) to open a valve hole. Therefore, a variable displacement compressor is prevented from operating with a large displacement when there is insufficient amount of refrigerant or when the speed of the compressor is high.Type: ApplicationFiled: December 20, 2005Publication date: January 18, 2007Inventors: Satoshi Umemura, Masahiro Kawaguchi, Masaki Ota, Tatsuya Hirose, Yuji Hashimoto

Patent number: 7137267Abstract: An apparatus for controlling a variable displacement compressor has an information detector and a controller. The information detector detects information about the thermal load on the refrigeration circuit. The controller determines a target value that reflects the displacement of the compressor based on the information about the thermal load detected by the information detector, and outputs the target value as a command value. When determining that the compressor is in a heavy load state based on information about a load on the compressor, the controller changes the command value to a value that causes the displacement of the compressor to become smaller than a displacement that corresponds to the determined target value.Type: GrantFiled: May 14, 2004Date of Patent: November 21, 2006Assignee: Kabushiki Kaisha Toyota JidoshokkiInventors: Masakazu Murase, Masahiro Kawaguchi, Hiroaki Kayukawa, Satoshi Umemura

Publication number: 20050287014Abstract: A displacement control valve for a variable displacement compressor includes a first valve hole forming a part of a supply passage and a second valve hole forming a part of a discharge passage. Displacement of a reciprocating body is transmitted to each of first and second valve bodies so that each valve body opens or closes the corresponding valve hole. When the reciprocating body is within a predetermined displacement range, a double closing state occurs, in which the first valve body closes the first valve hole and the second valve hole closes the second valve hole. When the reciprocating body is out of the displacement range, a single closing state occurs. Therefore, the control valve prevents the first valve hole from opening concurrently with the second valve hole.Type: ApplicationFiled: June 27, 2005Publication date: December 29, 2005Applicant: Kabushiki Kaisha Toyota JidoshokkiInventors: Satoshi Umemura, Masahiro Kawaguchi, Masaki Ota, Tatsuya Hirose, Yuji Hashimoto, Tetsuhiko Fukanuma

Patent number: 6970310Abstract: A disk system that conducts diagnoses of magnetic heads at regular or irregular interval to detect occurrence of unwritable failure. The history of regions on magnetic recording media where write operations took place is managed and a region where an unwritable failure occurred is specified. Data that corresponds to the unwritable failure is recovered by taking advantage of the redundancy of a RAID system. The disk system includes a unit that, upon reading data, checks whether the data to be read was written on the magnetic recording media through a normal write function. Through this, old data is prevented from being sent to host devices as a result of unwritable failure, and unwritable failures can be dealt with without increasing the processing time to detect unwritable failures.Type: GrantFiled: March 6, 2003Date of Patent: November 29, 2005Assignee: Hitachi, Ltd.Inventors: Masahiro Kawaguchi, Kenichi Kageura, Takao Sato
