Publication number: 20150256770Abstract: A solid-state image sensor device according to an embodiment includes an image pickup section, a first read signal line, a second read signal line, and an exposure time control section. The image pickup section includes a plurality of pixels arranged two-dimensionally in a matrix form. The first read signal line controls reading of charge accumulated in the plurality of pixels and be connected to a first pixel arranged in a center of a first row on which the plurality of pixels are arranged. The second read signal line controls reading of charge accumulated in the plurality of pixels and be connected to a second pixel arranged in a periphery outside the center of the first row. The exposure time control section performs control so that an exposure time of the second pixel becomes longer than an exposure time of the first pixel.Type: ApplicationFiled: September 3, 2014Publication date: September 10, 2015Applicant: Kabushiki Kaisha ToshibaInventors: Shoji SETA, Fumio Izawa

Patent number: 6507365Abstract: A solid-state imaging device with a variable (continuous) electronic shutter function comprises an imaging area where unit cells with photodiodes acting as pixels are arranged two-dimensionally, read lines for driving the read transistors in each pixel row, vertical selection lines for driving the vertical selection transistors in each pixel row, a vertical driving circuit for selectively driving vertical selection lines, vertical signal lines for outputting the signal from each unit cell in the pixel rows driven sequentially, and a row selection circuit for controlling the vertical driving circuit in such a manner that the vertical driving circuit drives the read transistors in each pixel row with the desired signal storage timing and signal read timing twice in that order and thereby drives the vertical selection transistors in the pixel row in synchronization with the signal read timing.Type: GrantFiled: November 30, 1999Date of Patent: January 14, 2003Assignee: Kabushiki Kaisha ToshibaInventors: Nobuo Nakamura, Yoshitaka Egawa, Shinji Ohsawa, Yukio Endo, Yoshiyuki Matsunaga, Yoriko Tanaka, Fumio Izawa, Hiroki Miura, Ryohei Miyagawa, Ikuko Inoue, Tsuyoshi Arakawa, Yoshiyuki Tomizawa, Makoto Hoshino

Patent number: 5035633Abstract: Disclosed is a data-processing apparatus comprising a data-processing unit, a connector unit, a pin-protecting member, and lock members. The lock members hold the pin-protecting member in a first position where the pin-protecting member opposes the pins and prevents anything other than the card-shaped recording medium from abutting on the pins and protects the pins from dust. When a card-shaped recording medium is inserted into the apparatus, the lock members release the pin-protecting member from the first position, whereby the pin-protecting member is moved to a second position. In the second position, the pin-protecting member allows an electrical connection between the pins and the connector of the recording medium. When the recording medium is pulled from the apparatus, the pin-protecting member is moved from the second position back to the first position.Type: GrantFiled: February 23, 1990Date of Patent: July 30, 1991Assignee: Kabushiki Kaisha ToshibaInventors: Hiromichi Kobayashi, Fumio Izawa

Patent number: 4963999Abstract: A tape position detection apparatus is disclosed wherein a tape is first fed in a forward direction from one reel to another for a predetermined period of time, under the control of a tape transit control circuit. When the reels rotate, respective pulse generators generate pulses which are counted by corresponding reel counters. The counting periods are set by control circuits, and upon completion of a counting period, the count obtained is stored as first count data in a memory circuit. Also, as a capstan for feeding the tape rotates, a corresponding pulse generator generates pulses which are counted by capstan counters. In accordance with the count, an operational circuit calculates the residual amount of tape for presentation on a display.Type: GrantFiled: February 22, 1988Date of Patent: October 16, 1990Assignee: Kabushiki Kaisha ToshibaInventors: Masaaki Utsunomiya, Fumio Izawa

Patent number: 4825056Abstract: A thin-film type electromagnetic transducer formed on a nonmagnetic substrate by a thin-film forming process. The transducer includes a magnetic core formed on the substrate by the thin-film forming process, and a conductor coil formed on the substrate by the thin-film forming process, so as to be wound around the core. The core is shaped so that a leakage flux generated along the plane of the substrate is greater than that generated in a direction intersecting with the plane of the substrate, the leakage fluxes being generated from the core when a current is supplied to the coil. In a method for transferring signals from the thin-film type electromagnetic transducer described above, a magnetic head is located so as to face that region of the core of the transducer where the maximum leakage flux is generated.Type: GrantFiled: November 20, 1986Date of Patent: April 25, 1989Assignee: Kabushiki Kaisha ToshibaInventors: Toshihiko Ohta, Fumio Izawa

Patent number: 4803350Abstract: An IC element is incorporated in a card substrate, and includes at least a memory in which data can be stored and from which it can be read out. A pre-processing section is incorporated in the card substrate, to receive an output from the IC element. The pre-processing section pre-enhances readout data from the memory of the IC element, so as to substantially attenuate high-frequency components of the data. A transducer is incorporated in the card substrate to receive an output from the pre-processing section. The transducer generates a magnetic field corresponding to the data read out from the memory of the IC element and supplied via the pre-processing section.Type: GrantFiled: January 28, 1988Date of Patent: February 7, 1989Assignee: Kabushiki Kaisha ToshibaInventors: Fumio Izawa, Masayuki Shinozaki
