Publication number: 20190040815Abstract: A head-side jacket through which coolant flows is formed in a cylinder head. A main circulation path and a sub circulation path through which coolant fed from a coolant pump respectively circulates are formed. The head-side jacket is separated into an exhaust-port side jacket formed around an exhaust port, and a combustion-chamber-side jacket closer to a combustion chamber than the exhaust-port-side jacket. A heat exchanger is not formed in the main circulation path including the combustion-chamber-side jacket, but is formed in the sub circulation path excluding the combustion-chamber-side jacket and including the exhaust-port-side jacket.Type: ApplicationFiled: August 1, 2018Publication date: February 7, 2019Inventors: Ryotaro Nishida, Tomohiro Koguchi, Mikimasa Kawaguchi, Yuichi Ayukawa, Tatsuya Takahata, Takayuki Tominaga, Shinji Watanabe, Keita Watanabe

Patent number: 9750477Abstract: A measurement area selection circuit has an irradiation field determination unit, an object area determination unit, and a measurement area determination unit. The irradiation field determination unit determines an irradiation field of an imaging surface of an FPD. The object area determination unit determines an object area from a comparison result between a first expected received dose of a directly exposed area and dose detection signals of detection pixels situated in the irradiation field. The measurement area determination unit determines a measurement area, which corresponds to a region of interest, from a comparison result between a second expected received dose of the measurement area and the dose detection signals of the detection pixels situated in the irradiation area and the object area. The dose detection signals of the detection pixels situated in the measurement area are used for AEC.Type: GrantFiled: March 26, 2014Date of Patent: September 5, 2017Assignee: FUJIFILM CorporationInventors: Yusuke Kitagawa, Takashi Tajima, Keita Watanabe, Takeshi Kamiya

Patent number: 9678226Abstract: A flat panel detector (FPD) includes an imaging panel having pixels arranged in a matrix, a gate driver for turning thin film transistors (TFTs) of the pixels ON and OFF, a radiation detecting section for detecting the start of x-ray radiation from the x-ray source, and a controller. The controller controls the gate driver to turn the TFTs ON periodically to reset dark charges of the pixels. Before starting a charge accumulating operation for accumulating signal charges for imaging, the controller controls the gate driver to turn the TFTs OFF so that the radiation detecting section may detect the start of x-ray radiation on the basis of charge leaks from the pixels. When the start of x-ray radiation is detected, the controller starts the charge accumulating operation while keeping the TFTs in the OFF condition. Thereafter, the TFTs are turned ON to read out the accumulated signal charges.Type: GrantFiled: June 30, 2015Date of Patent: June 13, 2017Assignee: FUJIFILM CorporationInventor: Keita Watanabe

Patent number: 9146326Abstract: An x-ray image detector monitors the intensity of incident x-rays to detect an end of radiation from an x-ray source when the x-ray intensity decreases to a threshold level or less. The x-ray intensity gets down to zero with a variable time lag from the start of decreasing, called radiation wave tail. Depending on the gradient of declivity in time curve of the decreasing x-ray intensity, calculated at the time when the end of radiation is detected, the x-ray image detector decides a delay time from the end-of-radiation detection time to a reading start time to start reading signal charges from the image detector. Thus, the reading start time may be adjusted to the point when the x-ray intensity gets down to zero, which will improve S/N ratio and prevent shading artifacts.Type: GrantFiled: May 24, 2012Date of Patent: September 29, 2015Assignee: FUJIFILM CorporationInventors: Takeshi Kuwabara, Keita Watanabe, Jun Enomoto, Yasufumi Oda, Takeshi Koishi

Publication number: 20150085980Abstract: A radiological image-capturing device includes: a first read control section that executes a first read mode in which electric signals stored in a plurality of pixels are read out simultaneously in units of a plurality of rows; and an emission-start determining section that determines that the emission of radiation from a radiation source onto an image-capturing panel has started when the values of the electric signals read by the first read control section have become greater than an arbitrarily settable threshold.

Patent number: 8983035Abstract: A flat panel detector has pixels for obtaining image signals and detective pixels for detecting the amount of incident x-rays. A signal processing circuit is of a pipeline-type, wherein first and second buffer memories are connected to the output of an A/D converter. In a dose detecting operation, the signal processing circuit repeats primary cycles alternately with secondary cycles of a shorter length than the primary cycles. In the primary cycle, a dose detection signal based on electric charges from the detective pixels is input in the first buffer memory and, simultaneously, a dummy signal is output from the second buffer memory. In secondary cycle, the dose detection signal is output from the first buffer memory and, simultaneously, a second dummy signal is input in the second buffer memory. On the basis of the dose detection signals, a start-of-radiation detector detects the start of x-ray radiation.Type: GrantFiled: November 21, 2012Date of Patent: March 17, 2015Assignee: FUJIFILM CorporationInventors: Kentaro Noma, Kenji Nakamura, Naoto Iwakiri, Kouichi Kitano, Keita Watanabe

Patent number: 8953744Abstract: An FPD, being offline from an X-ray source, detects X-ray irradiation from the X-ray source to detect an X-ray image. The FPD includes pixels arranged in two dimensions, scan lines corresponding to respective rows of the pixels, signal lines corresponding to respective columns of the pixels, and switching elements provided to the respective pixels to allow performing accumulation operation or readout operation. At least one of the pixels is used as a detection pixel to detect a start of the X-ray irradiation. First and second voltage signals are obtained successively through the signal line to which the detection pixel is connected. The start of the X-ray irradiation is judged based on a difference between the first and second voltage signals.Type: GrantFiled: January 31, 2012Date of Patent: February 10, 2015Assignee: FUJIFILM CorporationInventors: Keita Watanabe, Kentaro Noma

Patent number: 8866101Abstract: Binning readout reads out electric charge accumulated in pixels to signal lines in blocks of a plurality of adjoining pixel-rows. A correction image generator of a line defect corrector scales up an image size of a reference frame image RP outputted by the binning readout and corrects pixel values of the reference frame image RP, to produce a correction image RPC to be used for correction of a line defect occurring in an X-ray image XP. The scale-up is performed by applying row interpolation processing to the reference frame image RP. The correction of the pixel values is performed by multiplying the reference frame image RP after being subjected to the row interpolation processing by a correction coefficient. An adder adds the correction image RPC to the X-ray image XP, and produces an X-ray image XPC in which the line defect is corrected.Type: GrantFiled: March 28, 2014Date of Patent: October 21, 2014Assignee: FUJIFILM CorporationInventors: Keita Watanabe, Kentaro Noma, Yasufumi Oda
