Patent number: 11953317Abstract: A reference core position calculation device 100 that calculates a reference core position of an elevator shaft in which an elevator is to be installed includes a measurement unit 101 and a calculation unit 112. The measurement unit 101 measures a dimension of each portion of the elevator shaft. The calculation unit 112 calculates portion dimension values of the elevator shaft based on the reference core position and the dimension of each portion measured by the measurement unit 101. When the reference core position is a first reference core position, the calculation unit 112 determines whether portion dimension values of the elevator shaft calculated based on the first reference core position satisfy a predetermined specification.Type: GrantFiled: December 5, 2019Date of Patent: April 9, 2024Assignee: Hitachi Building Systems Co., Ltd.Inventors: Hirofumi Taguchi, Naoaki Noguchi, Daisuke Matsuka, Nobuaki Yagi, Masato Itou

Patent number: 9237627Abstract: Short circuit failures and open circuit failures of light-emitting elements used for the backlight in an LCD panel can be reliably and easily detected. The voltage at the node between each series-connected light-emitting element array and a drive circuit is detected as a monitored voltage. A maximum detector detects the highest and a minimum detector detects the lowest of these monitored voltages. Short circuit or open circuit failure of a light-emitting element is detected by comparing the voltage difference between the maximum detector output and the minimum detector output with a specific reference voltage.Type: GrantFiled: September 25, 2014Date of Patent: January 12, 2016Assignee: PANASONIC CORPORATIONInventors: Go Takata, Shinichiro Kataoka, Yasunori Yamamoto, Tsukasa Kawahara, Ryuji Ueda, Daisuke Itou

Patent number: 8775891Abstract: A transmitting circuit transmits data to which an error detection code is attached to a receiving circuit via a transmission path. When detecting the error of the data received via the transmission path, a receiving circuit transmits a retransmit request for the data in which the error is detected to the transmitting circuit. The receiving circuit enters a termination unit adjustment period using the error detection of the received data as a trigger and updates the resistance values of a receiving side termination unit installed at the termination of the transmission path to an appropriate value within the termination unit adjustment period.Type: GrantFiled: April 20, 2010Date of Patent: July 8, 2014Assignee: Fujitsu LimitedInventors: Junji Ichimiya, Hiroshi Nakayama, Daisuke Itou, Shintaro Itozawa

Patent number: 8499125Abstract: To prevent a decrease in performance of controlling a snoop tag. A queue is stored with REPLACE target WAY information and an index as an entry associated with a REPLACE request received from a processor, the index stored in the queue is compared with an index of a subsequent READ request, and, as a result of the comparison, a process based on the index-coincident READ request is executed with respect to the snoop tag corresponding to a content of a cache memory of the processor. Further, the REPLACE target WAY information of the READ request is replaced with the WAY information in the index-coincident entry within the queue.Type: GrantFiled: April 24, 2007Date of Patent: July 30, 2013Assignee: Fujitsu LimitedInventors: Makoto Hataida, Toshikazu Ueki, Takaharu Ishizuka, Takashi Yamamoto, Yuka Hosokawa, Takeshi Owaki, Daisuke Itou

Patent number: 8401139Abstract: A transmission LSI calculates a buffer usage rate in accordance with data stored in a buffer in a transmission data processing unit and determines, in accordance with the calculated buffer usage rate, the number of signal lines that perform a phase readjustment and the timing thereof. Then, the transmission LSI and a receiving LSI perform a phase adjustment using some of the signal lines and continues a data transfer using the rest of the signal lines. Accordingly, it is possible to maintain the optimum phase of a clock without delaying the data transfer.Type: GrantFiled: September 1, 2011Date of Patent: March 19, 2013Assignee: Fujitsu LimitedInventors: Shintaro Itozawa, Hiroshi Nakayama, Junji Ichimiya, Daisuke Itou

Patent number: 8181064Abstract: A northbridge, when detecting a synchronization break of a redundant CPU, stops the operation of an abnormal CPU bus where an error has occurred and the firmware in a firmware hub instructs the northbridge to inhibit an external instruction. In addition, the firmware saves the inside information of a normal CPU connected to a normal CPU bus and cache data on a memory and the northbridge issues reset to all CPUs in the home system board. The firmware then restores the inside information of the CPU saved on the memory to all CPUs and instructs the northbridge to cancel the inhibition of the external instruction.Type: GrantFiled: March 24, 2010Date of Patent: May 15, 2012Assignee: Fujitsu LimitedInventors: Takeshi Owaki, Takaharu Ishizuka, Toshikazu Ueki, Makoto Hataida, Yuka Hosokawa, Atsushi Morosawa, Takashi Yamamoto, Daisuke Itou

Patent number: 8159140Abstract: The load driving apparatus according to the present invention includes a load current setting signal generating section, a load current generating section, a reference voltage generating section and a drive voltage generating section. The load current setting signal generating section generates a desired load current setting signal. The load current generating section generates a load current based on the load current setting signal to drive the load. The reference voltage generating section generates a reference voltage based on the load current setting signal. The drive voltage generating section generates a drive voltage, supplies the drive voltage to the load, generates a between-both-terminals voltage between both terminals of the load current generating section based on the drive voltage and controls the drive voltage so that the difference between the between-both-terminals voltage and the reference voltage becomes small.Type: GrantFiled: September 3, 2009Date of Patent: April 17, 2012Assignee: Panasonic CorporationInventors: Go Takata, Shinichiro Kataoka, Yasunori Yamamoto, Tsukasa Kawahara, Ryuji Ueda, Daisuke Itou
