Patent number: 10006395Abstract: A heat-ray type of airflow meter has a signal processor for converting a detected intake air quantity into a frequency signal. An engine controller has a conversion table for converting the frequency signal into an air quantity. The signal processor and the conversion table have features such that the frequency increases as the magnitude of a positive air quantity increases, and the frequency decreases as an absolute value of a negative air quantity increases. In the conversion table, a prescribed positive air quantity value is assigned a dummy output for frequencies lower than a prescribed threshold value. Under normal circumstances, frequencies lower than a minimum value are not used. The frequency decreases to near 0 Hz when there is a disconnection or a short circuit, the dummy output is therefore output, and an injection quantity equal to or greater than a misfire limit is ensured.Type: GrantFiled: January 26, 2015Date of Patent: June 26, 2018Assignee: Nissan Motor Co., Ltd.Inventors: Yukinobu Ito, Yukimi Mizuno

Patent number: 5384537Abstract: A nuclear magnetic resonance imaging system with the intercom facility in which the disturbing and potentially harmful large noise due to the application of the reading gradient field pulses can be reduced at the exterior of the examination room. In the system, a connection between the microphone and the loudspeaker for transmitting the sounds generated inside the examination room to the exterior of the examination room is controlled according to the pulse sequence specified by the sequence controller such that the microphone and the loudspeaker are disconnected whenever the application of the reading gradient field pulse takes place.Type: GrantFiled: April 28, 1993Date of Patent: January 24, 1995Assignee: Kabushiki Kaisha ToshibaInventors: Yukinobu Ito, Eiji Moriya

Patent number: 5118948Abstract: A radiation ray (gamma ray) radiated from a test subject previously dosed with radioisotope is incident on a scintillator and converted into scintillation light. A plurality of photomultipliers arranged in a hexagon receive and convert the scintillation light into electrical signals. Photomultipliers arranged in parallel with sides of the hexagon constitute a group. Output signals of the photomultipliers are supplied to a first position detector for detecting a group of photomultipliers which receives the scintillation light and deriving position information Xo and Yo representing the approximate gamma ray incident position. The position information Xo and Yo and the output signals of the photomultiplier are supplied to a second position detector for deriving position information x and y representing the precise gamma ray incident position. Outputs of the photomultiplier are supplied to a pulse height analyzer which derives incident radiation energy information z.Type: GrantFiled: March 14, 1990Date of Patent: June 2, 1992Assignee: Kabushiki Kaisha ToshibaInventors: Yukinobu Ito, Akira Tsukamoto, Nobutoshi Nakayama, Kazuhiro Tsuda

Patent number: 4989075Abstract: A solid-state image sensing device comprises photoelectric image sensors disposed in parallel with each other for receiving an optical image, vertical transfer members coupled to the image sensors, and horizontal transfer members coupled to output of the vertical transfer members. The vertical transfer members are each formed of R, G and B vertical transfer arrays provided for R, G and B color image signals output from a photoelectric image sensor. Outputs of the R, G and B vertical transfer arrays are coupled to R, G and B horizontal transfer arrays. The R, G and B vertical transfer arrays store the R, G and B image signals, and transfer the stored R, G and B image signals to the R, G and B horizontal transfer arrays.Type: GrantFiled: April 30, 1990Date of Patent: January 29, 1991Assignee: Kabushiki Kaisha ToshibaInventor: Yukinobu Ito

Patent number: 4819188Abstract: In a radiation image recording system for recording a processed image on a recording medium by frequency emphasis processing and gradation processing of radiation image data from an object to be examined, an image processing apparatus performs frequency emphasis processing and gradation processing of the radiation image data for a later image recording stage. The image processing apparatus calculates two unsharp mask data Sus1 and Sus2 for two different mask sizes, and substantially simultaneously forms two processed image data by frequency emphasis processing and gradation processing of the radiation image data using the unsharp mask data Sus1 and Sus2.Type: GrantFiled: November 22, 1985Date of Patent: April 4, 1989Assignee: Kabushiki Kaisha ToshibaInventors: Mitsuyoshi Matsubara, Yukinobu Ito

Patent number: 4482958Abstract: A data processing device applied to a computed tomography system which examines a living body utilizing radiation of X-rays is disclosed. The X-rays which have penetrated the living body are converted into electric signals in a detecting section. The electric signals are acquired and converted from an analog form into a digital form in a data acquisition section, and then supplied to a matrix data-generating section included in the data processing device. By this matrix data-generating section are generated matrix data which correspond to a plurality of projection data. These matrix data are supplied to a partial sum-producing section. The partial sums respectively corresponding to groups of the matrix data are calculated in this partial sum-producing section and then supplied to an accumulation section. In this accumulation section, the final value corresponding to the total sum of the matrix data is calculated, whereby the calculation for image reconstruction is performed.Type: GrantFiled: November 12, 1981Date of Patent: November 13, 1984Assignee: Tokyo Shibaura Denki Kabushiki KaishaInventors: Nobutoshi Nakayama, Yukinobu Ito, Eitaro Nishihara, Kazuhide Iwata, Shigeki Shibayama
