Publication number: 20220150675Abstract: A communication terminal includes an acceleration sensor, a position acquisition antenna, a communication interface, and a processor. The processor transmits acceleration information acquired using the acceleration sensor and present position information acquired using the position acquisition antenna in a normal operation mode via the communication interface. The processor changes to an abnormal state when detecting a vibration equal to or higher than a first predetermined value using the acceleration sensor, and increases a frequency of acquisition or transmission of the acceleration information or the present position information in the abnormal state.Type: ApplicationFiled: July 30, 2019Publication date: May 12, 2022Applicant: SHARP KABUSHIKI KAISHAInventors: Takashi SAKAMOTO, KATSUO DOI, KEN NAKASHIMA, TAKEHIKO NAKAGAWA, Shota TSUBOKURA

Patent number: 10088209Abstract: An air conditioner 1 of the embodiment of the present invention, when all compressors 21a-21c have been stopping for a given time or more, starts an air conditioning operation without performing pressure equalizing control in switch units 6a-6d with starting the operation of the air conditioner 1. Also, when the stopping time of all compressors 21a-21c is less than the given time, the air conditioner 1 performs the pressure equalizing control by controlling switch units 6a-6d with starting the operation of the air conditioner 1. In this case, when the stopping time reaches the given time during execution of the pressure equalizing processing control, the pressure equalizing processing control being executed is stopped and the air conditioning operation is started.Type: GrantFiled: January 3, 2013Date of Patent: October 2, 2018Assignee: Fujitsu General LimitedInventors: Keito Kawai, Hideya Tamura, Takahiro Matsunaga, Shinju Watanabe, Takashi Kimura, Kotaro Toya, Yasuhiro Oka, Ken Nakashima

Patent number: 9765997Abstract: A CPU 110 compares the extracted outside air temperature with a first low pressure saturation temperature. When the outside air temperature is lower than the first low pressure saturation temperature, the CPU 110 switches a first three-way valve 22 and a second three-way valve 23 so that a second outdoor heat exchanger 25 is used as a condenser and that a first outdoor heat exchanger 24 is not used. When the outside air temperature is higher than a second low pressure saturation temperature which is the first low pressure saturation temperature to which a predetermined temperature is added, the CPU 110 switches the first three-way valve 22 and the second three-way valve 23 so that the first outdoor heat exchanger 24 is used as a condenser and that the second outdoor heat exchanger 25 is not used.Type: GrantFiled: July 19, 2012Date of Patent: September 19, 2017Assignee: Fujitsu General LimitedInventors: Ken Nakashima, Hideya Tamura, Takahiro Matsunaga, Shinju Watanabe, Keito Kawai, Kotaro Toya, Yasuhiro Oka

Patent number: 9739521Abstract: When the temperatures of outdoor heat exchangers 23a and 23b detected by outdoor heat exchanger temperature sensors 57a and 57b become equal to or higher than 5 degrees C. and the sucking superheating degrees of compressors 21a and 21b become equal to or lower than 0 degrees C. while an air conditioning apparatus 1 is performing the reverse defrosting operation, the reverse defrosting operation is stopped and the heating dominant operation is resumed. At this time, the total operating times of the compressors 21a and 21b are reset. The sucking superheating degrees of the compressors 21a and 21b are obtained by subtracting the low pressure saturation temperatures calculated from the sucking pressures of the compressors 21a and 21b, from the temperatures of the refrigerants sucked into the compressors 21a and 21b which temperatures are detected by the sucking temperature sensors 54a and 54b.Type: GrantFiled: January 3, 2013Date of Patent: August 22, 2017Assignee: Fujitsu General LimitedInventors: Keito Kawai, Hideya Tamura, Takahiro Matsunaga, Shinju Watanabe, Takashi Kimura, Kotaro Toya, Yasuhiro Oka, Ken Nakashima

Patent number: 9046284Abstract: An air conditioning apparatus 1 includes first start control and second start control as its start control. In the first start control, first outdoor heat exchangers 24a, 24b are controlled to function as evaporators and second outdoor heat exchangers 25a, 25b are controlled to function as condensers. Thus, even when the compressors 21a, 21b are driven on at a given rotation number, the discharge pressures thereof can be prevented from increasing, thereby being able to prevent the internal pressures of the compressors 21a, 21b from increasing. Also, after end of the first start control, the first outdoor heat exchangers 24a, 24b and second outdoor heat exchangers 25a, 25b are all controlled to function as evaporators, and the compressors 21a, 21b are driven on at a given rotation number. This can shorten the rising time of the heating capacity in the start of the normal heating operation.Type: GrantFiled: September 13, 2012Date of Patent: June 2, 2015Assignee: FUJITSU GENERAL LIMITEDInventors: Hideya Tamura, Takahiro Matsunaga, Shinju Watanabe, Keito Kawai, Takashi Kimura, Kotaro Toya, Yasuhiro Oka, Ken Nakashima

Patent number: 7852823Abstract: When a transmission station having a voluntary transmission right transmits FINALL FRAME as a TXOP ending frame to HC, the HC transmits an acknowledgement frame ACK after SIFS following the reception of FINAL FRAME. Here, when the transmitting station has detected that no frame transmission is performed over the communication network from any other ESTAs in PIFS after the transmission of FINAL FRAME, FINAL FRAME is retransmitted in DIFS after the transmission of FINAL FRAME. By performing such a communication management, it is possible to accurately manage a voluntary transmission right even when the communication medium has a low reliability in a network in which one network pathway is time-shared by a plurality of communication apparatuses.Type: GrantFiled: September 12, 2002Date of Patent: December 14, 2010Assignee: Sharp Kabushiki KaishaInventors: Ken Nakashima, Yoshihiro Ohtani, Toru Ueda, Srinivas Kandala
