Patent number: 12146991Abstract: The noise calculation unit applies a statistical process for the measurement signal of the first number of data to calculate the noise value. The calculation threshold setting unit sets the calculation threshold based on the noise value. The period determination unit determines a period where a difference between the measurement signal and a moving average value calculated in a previous cycle exceeds the calculation threshold, to be the non-calculation period of the baseline. The moving average calculation unit is configured such that the measurement signal in a period excluding the non-calculation period is moving-averaged for each second number of data to calculate the moving average value. The first number of data and the second number of data are set independently.Type: GrantFiled: January 7, 2021Date of Patent: November 19, 2024Assignee: DENSO CORPORATIONInventors: Shunsuke Kimura, Hidekazu Adachi

Publication number: 20210349184Abstract: A detection unit is configured to perform a top detection process in which a maximum value of intensity of a detection signal is stored, and when the intensity of the detection signal is reduced from the stored maximum value to a value that is smaller by a predetermined top determination value, a point of the detection signal that indicates the stored maximum value is determined as a top of a crest of a waveform of the detection signal. Furthermore, the detection unit is configured to perform a bottom detection process in which after the top of the crest is detected, a minimum value of the intensity of the detection signal is stored, and when the intensity of the detection signal is increased from the stored minimum value to a value that is larger by a predetermined bottom determination value, a point of the detection signal that indicates the stored minimum value is determined as a bottom of a trough of the waveform of the detection signal.Type: ApplicationFiled: July 19, 2021Publication date: November 11, 2021Inventor: Hidekazu ADACHI

Patent number: 9465730Abstract: Different block management values that sequentially increase are set for a plurality of blocks to indicate active states of the blocks. For example, a first block management value “$1111” is stored in a first block, and a second management value “$1112” is stored in a second block. Thus, even when more than one block is in an active state, an updated value is read from the block that stores a larger block management value. This allows for the true updated value to be read.Type: GrantFiled: May 1, 2012Date of Patent: October 11, 2016Assignee: KABUSHIKI KAISHA TOKAI RIKA DENKI SEISAKUSHOInventors: Kazunori Arakawa, Tetsuya Egawa, Hidekazu Adachi

Patent number: 9021184Abstract: In a flash memory device, after an updated value is copied from a first block to a second block, a block management value of the first block is set to an unused state, and maintenance is performed to erase data from the first block. When performing maintenance, the block management value of the first block B1 is rewritten from “$FFF0” to “$FFFF.” When a reset occurs and the power supply is deactivated during the maintenance, the digit of “$0” in the block management value may become “1” to “E” of the hexadecimal system. In this manner, when the block management value includes a single digit of “1” to “E” and three digits of “F,” the reading of an updated value from the block corresponding to the block management value is restricted.Type: GrantFiled: May 11, 2012Date of Patent: April 28, 2015Assignee: Kabushiki Kaisha Tokai Rika Denki SeisakushoInventors: Yosuke Ohashi, Kazunori Arakawa, Tetsuya Egawa, Hidekazu Adachi

Patent number: 4915511Abstract: A roller chain having plural bearing rollers located around the outer-periphery of a bushing, rollers surrounding the plural bearing rollers and thrust rings located at the gaps between rollers and inner link plate. The running resistance, abrasion and durability against the lateral force of the chain are improved.Type: GrantFiled: June 26, 1986Date of Patent: April 10, 1990Assignee: Tsubakimoto Chain Co.Inventors: Katsumi Kotegawa, Makoto Kanehira, Kiyofumi Suzuki, Shinichi Hayashi, Hidekazu Adachi
