Patent number: 11980419Abstract: An exemplary OCT apparatus includes a scanner, controller, phase information generator, phase information processor. The scanner applies an OCT scan to an object using an optical scanner. The controller controls the scanner to perform a first scan that scans a cross section of the object in a first scan direction and a second scan that scans a cross section of the object in a second scan direction opposite to the first scan direction. The phase information generator generates first phase information based on first acquisition data acquired by the first scan and second phase information based on second acquisition data acquired by the second scan. The phase information processor generates composite phase information based on the first phase information and the second phase information.Type: GrantFiled: July 10, 2020Date of Patent: May 14, 2024Assignee: TOPCON CORPORATIONInventors: Jun Sakai, Toshihiro Mino

Patent number: 10054555Abstract: Disclosed are an X-ray transmission inspection apparatus and an inspection method using the same that are capable of preventing over-detection and erroneous detection of foreign matter even when variations in vertical position of the sample occur. The X-ray transmission inspection apparatus includes: an X-ray source (2) irradiating a sample with X-rays; a sample moving device (3) moving the sample S continuously to a predetermined direction while X-rays X are emitted from the X-ray source; a time delay integration sensor (TDI sensor) (4) provided opposed to the X-ray source based on the sample, and detecting the X-rays transmitted through the sample; a distance sensor (5) measuring a distance between the X-ray source and the sample; and a TDI controller (6) controlling the TDI sensor by changing a charge transfer speed of the TDI sensor (4) in real time based on variations in the distance measured by the distance sensor.Type: GrantFiled: July 27, 2016Date of Patent: August 21, 2018Assignee: HITACHI HIGH-TECH SCIENCE CORPORATIONInventors: Yoshiki Matoba, Akihiro Takeda, Shingo Tsuboi, Toshihiro Sakai

Patent number: 8572828Abstract: The present invention includes a mounting structure for mounting a component between a first member and a second member. According to the mounting structure, the component is first placed on a surface of the first member. Then, the second member is fitted with the component by a fitting device, so that the component is positioned relative to the second member. Thereafter, the component is fixed in position relative to the first member by a joint device.Type: GrantFiled: September 12, 2008Date of Patent: November 5, 2013Assignees: Aisan Kogyo Kabushiki Kaisha, Toyota Jidosha Kabushiki KaishaInventors: Toshihiro Sakai, Akihisa Hotta, Koji Katano, Toshiyuki Inagaki, Nobutaka Teshima

Patent number: 5016165Abstract: A direct memory access (DMA) controlled system which performs DMA data transfer between a main memory, a cache memory, and disk memories while exchanging DMA transfer requests and acknowledgements among disk control units, a memory-to-memory transfer control unit, and a common DMA control unit. The data transfer speed between the main memory and the cache memory is variable according to the load condition of the DMA control unit for the disk memories, enabling the transfer capability of the DMA control unit to be kept at a continually high level.Type: GrantFiled: January 12, 1988Date of Patent: May 14, 1991Assignee: Fujitsu LimitedInventors: Akinao Tanikawa, Toshiharu Ohshima, Toshihiro Sakai

Patent number: 4374410Abstract: In a data processing system in which a data processing unit has an M-bit address register and is connected via an N-bit address bus with a memory (where N<M<2n), the content of the address register is sent out on the address bus in two stages. Namely, high-order N bits of the address register are sent out first, and low-order N-bits are sent out next. One of the bits of the address register is sent out twice by the first and second sending-out operations. The system includes, in combination, various gates and a multiplexer to accomplish data transfer selectively for both virtual memory and real memory operation.Type: GrantFiled: August 8, 1979Date of Patent: February 15, 1983Assignees: Fujitsu Limited, USAC Electronic Industrial Co., Ltd.Inventors: Toshihiro Sakai, Tetsuji Kuhara
