Patent number: 8797041Abstract: A discharge ionization current detector using a low-frequency dielectric barrier discharge with an improved S/N ratio is provided. A current detector 20 is disposed between an excitation high-voltage power source 8 and a discharge electrode 5 to detect a discharge current flowing in pulses due to plasma generation. The detection signal of the current detector 20 and an output signal from a current amplifier 18 for amplifying an ion current are inputted into an output extraction unit 21. The output extraction unit 21 detects a precipitous-rise portion of the discharge current detection signal and generates a trigger signal, and then extracts an ion current signal for a predetermined time period from the trigger signal. This can remove an influence of a noise appearing in a signal during a time period where no plasma emission is generated, thereby improving the S/N ratio of the detection signal.Type: GrantFiled: April 21, 2011Date of Patent: August 5, 2014Assignees: Shimadzu Corporation, Osaka UniversityInventors: Kei Shinada, Shigeyoshi Horiike, Takahiro Nishimoto, Katsuhisa Kitano

Patent number: 8783121Abstract: A blood collecting apparatus includes a cleaning solution piping. The cleaning solution piping feeds into a flow path a heparin solution which is a liquid other than blood to be measured, in order to return the blood present in the flow path to a catheter disposed upstream of a blood inlet of the flow path. Thus, the blood having flowed into the flow path in an amount more than is necessary for blood collection, which corresponds to a portion returned to the upstream catheter of the blood to be measured present in the flow path, can be used in a next blood collection. As a result, the amount of collected blood can be reduced. The liquid to be measured is separated apart by means of a gas, and the flow path is cleaned in a way to leave no impurities in the flow path, thereby preventing impurities from mixing into the liquid to be measured.Type: GrantFiled: March 19, 2009Date of Patent: July 22, 2014Assignees: Shumadzu Corporation, National Institute of Radiological SciencesInventors: Nobuya Hashizume, Keishi Kitamura, Takahiro Nishimoto, Yuichi Kimura, Chie Seki, Iwao Kanno

Patent number: 8773138Abstract: A discharge ionization current detector using a low-frequency barrier discharge is provided to improve the linearity of detection sensitivity with respect to a sample introduction amount. From a lower end of a lower gas passage connected to a lower end of an upper gas passage, a dilution gas is supplied upward against a downward flow of a plasma gas. A gas discharge passage for discharging a plasma gas, the dilution gas and a sample gas is arranged between an ion-collecting electrode and a bias voltage application electrode. The sample gas introduced through a capillary tube is mixed with the plasma gas and the dilution gas due to a disturbed flow generated by collision of the plasma gas and the dilution gas. The sample component is efficiently ionized by light from the plasma without undergoing light-shielding effect of concentrated sample components.Type: GrantFiled: June 23, 2011Date of Patent: July 8, 2014Assignee: Shimadzu CorporationInventors: Kei Shinada, Shigeyoshi Horiike, Takahiro Nishimoto

Patent number: 8761643Abstract: Aspects described herein relate to a cap for a toner cartridge. In one example, the cap may be configured to close a toner supply opening of the toner cartridge. According to one or more aspects, the cap may include a sealing or covering portion configured to cover the toner supply opening and a shaft portion for rotatably supporting a to-be-detected rotary member. The to-be-detected rotary member 56 is rotatably supported around and fitted onto the shaft portion. Therefore, even if a toner supply opening of a cartridge is provided in a sidewall of the housing on a side where the to-be-detected rotary member is provided, e.g., a left sidewall, the toner supply opening and the to-be-detected rotary member can be provided in such a manner as to overlap each other.Type: GrantFiled: January 14, 2014Date of Patent: June 24, 2014Assignee: Brother Kogyo Kabushiki KaishaInventors: Motoaki Mushika, Tsutomu Suzuki, Yasuo Fukamachi, Fumikazu Sato, Hikaru Yoshizumi, Takahiro Nishimoto

Publication number: 20140145724Abstract: A low-OH-content quartz glass with an OH content equal to or lower than 5 ppm is used as a cylindrical tube (2) covering the surface of metallic plasma generation electrodes (4, 5 and 6) for generating a low-frequency barrier discharge. It has been found that, in the low-frequency barrier discharge, hydrogen and oxygen originating from the OH contained in a dielectric material are released into plasma gas for a long period of time, constituting a primary cause of an increase in the baseline current. The use of a low-OH-content quartz glass dramatically lowers the baseline current and thereby improves the S/N ratio and the detection limit.Type: ApplicationFiled: May 31, 2012Publication date: May 29, 2014Inventors: Kei Shinada, Shigeyoshi Horiike, Takahiro Nishimoto

Patent number: 8551760Abstract: [Problems] To immobilize a chain-type biopolymer in an elongated state at a predetermined position on a substrate. [Means for Solving Problems] A substrate (1) for immobilizing a biopolymer, which has a mask layer (2) provided with multiple through-holes at predetermined positions on a flat active face, is brought into contact with a solution containing a chain-type biopolymer (7). After thus immobilizing the nucleic acid molecule (7) on the active face within a through-hole (3) via physical adsorption or chemical binding, the mask layer (2) is dissolved in a solvent and thus removed while leaving the nucleic acid molecule (7a) alone having been immobilized on the active face within the through-hole (3). Subsequently, the nucleic acid molecule (7a) having been immobilized on the active face is elongated.Type: GrantFiled: September 5, 2005Date of Patent: October 8, 2013Assignee: Shimadzu CorporationInventors: Shigeyoshi Horiike, Yukio Oikawa, Takahiro Nishimoto

Patent number: 8358405Abstract: A blood collecting apparatus includes a main flow path and a pressure generator. The pressure generator is provided in an intermediate position of the main flow path to insert a gas as separators at designated predetermined intervals, thereby to take out blood to be measured, as separated in a time series. The blood can be taken out in minute volumes by inserting the separators consisting of the gas while feeding the blood continuously into the main flow path in this way. And consumption of the blood can be held down, and the amount of collected blood can be minimized. Since the operation to insert the separators is excellent in speed, repeated collection in a short time, i.e. frequency of blood collection, can be secured.Type: GrantFiled: January 22, 2008Date of Patent: January 22, 2013Assignees: Shimadzu Corporation, National Institute of Radiological SciencesInventors: Keishi Kitamura, Takahiro Nishimoto, Yuichi Kimura, Chie Seki, Iwao Kanno
