Abstract: A method for detecting a target nucleic acid fragment in a sample includes a step of contacting the sample with a gRNA complementary to the target nucleic acid fragment, a Cas protein, and a substrate nucleic acid fragment, in which the Cas protein is immobilized on a solid phase, a substrate nucleic acid fragment is labeled with a fluorescent substance and a quencher, in a case of being cleaved by nuclease activity of a three-part complex of the Cas protein, the gRNA, and the target nucleic acid fragment, fluorescent light is emitted, the contact is performed in a reaction space having a volume of 10 aL to 100 pL, thereby forming the three-part complex in a case where the target nucleic acid fragment is present in the sample, cleaving the substrate nucleic acid fragment, and separating the fluorescent substance from the quencher; and detecting the fluorescent light, in which the detection of the fluorescent light indicates the presence of the target nucleic acid fragment in the sample.

Abstract: A plurality of power supply circuits include a second power supply circuit for a CPU included in a control unit and a first power supply circuit for another circuit. An output voltage from the first power supply circuit is higher than an output voltage from the second power supply circuit. A range of input voltage is divided into three levels of voltage sub-ranges in accordance with a requirements specification. When the input voltage falls within a lower level voltage sub-range, both of an output function of the first power supply circuit and an output function of the second power supply circuit are stopped. When the input voltage falls within an intermediate level voltage sub-range, the output function of the first power supply circuit is stopped. When the input voltage falls within an upper level voltage sub-range, all circuits are controlled so as to operate.

Abstract: In an electric power steering device assisted by a brushless motor, an induced voltage from a brushless motor is detected when a main power supply is off. The motor is determined to be in a high rpm state when the induced voltage is in a first transient state from a voltage?a high rpm detection threshold Th1 to a voltage?Th1, thereby setting an intermittent excitation cycle of a revolution angle sensor connected to the motor to a short cycle. The motor is determined to be in a low rpm state when the induced voltage becomes a voltage?a high rpm detection threshold Th2 after a wait period corresponding to an electrical angle between peaks or valleys of an output voltage has elapsed in a second transient state from a voltage?Th1 to a voltage?Th2, thereby setting the cycle to a long cycle.

Abstract: A prover includes a measurement cylinder; a hydraulic cylinder coupled with a side of a downstream end of the measurement cylinder; a measuring piston that moves through a predetermined distance from an upstream side toward a downstream side through the measurement cylinder to eject a reference volume of fluid; and a piston rod that is movably accommodated in the hydraulic cylinder, and has the measuring piston and the piston rod separately constructed. The prover includes measurement standby position stop means, and when returning the measuring piston to a predetermined measurement standby position, the piston rod moves the measuring piston from the downstream side to the upstream side and the measurement standby position stop means stops the measuring piston at the predetermined measurement standby position, after which only the piston rod is caused to move from the upstream side to the downstream side and is accommodated in the hydraulic cylinder.

Abstract: A piston prover comprises a measurement cylinder; a hydraulic cylinder coupled with a downstream end of the measurement cylinder; a measuring piston that moves a predetermined distance through the measurement cylinder during a measurement due to a fluid flow to eject a reference volume of fluid; and a piston rod that is movably in the hydraulic cylinder, wherein the measuring piston and the piston rod are separately constructed. When returning the measuring piston to a predetermined upstream measurement standby position, the piston rod moves the measuring piston to set the measuring piston at the predetermined measurement standby position, and thereafter only the piston rod is moved from upstream to downstream and is accommodated in the hydraulic cylinder.

Abstract: A function for authenticating an operator to control whether to permit them to operate a vehicle (20) can be added to the vehicle by simple modification. An operation permission control device (22) is installed on the vehicle (20). The operation permission control device (22) incorporates a relay inserted in the middle of a start signal line (47) connecting a key switch (46) and vehicle start circuit (48) (starter relay of an engine-powered vehicle or main controller of a battery-powered vehicle) and can open and close the start signal line (47). The operation permission control device (22) reads data of a authentication card (34) carried by the operator, collates the read data with preprogrammed data in a removable set memory a (32). If the data match, the device connects the start signal line (47) to enable start of the vehicle.

Abstract: A catalyst for removing carbon monoxide (CO) in a hydrogen rich gas according to a water gas shift reaction is provided, which is characterized in that platinum and rhenium are supported on rutile titania as a support. This catalyst provides a high CO conversion at a relatively low reaction temperature between 200° C. and 300° C. and is excellent in cost/performance due to a reduction in amount of supported platinum. It is preferred that a weight ratio of an amount of supported platinum to an amount of supported rhenium is in a range of 3:1 to 1:1, and particularly 3:2. In addition, when the catalyst is produced by supporting rhenium first and then platinum on the support, the catalyst performance can be remarkably improved.
