摘要:
A measurement method of peroxidase activity is based on reaction of o-phenylenediamine and hydrogen peroxide in the presence of peroxidase. This method includes preparing and storing a first reagent containing o-phenylenediamine and having a first pH value higher than a second pH value at which the reaction is conducted, and preparing and storing a second reagent having a buffering capability larger than the first reagent. At the time of measurement, the stored first and second reagents are mixed together with a sample containing peroxidase, and a predetermined amount of hydrogen peroxide to provide a reaction mixture having the second pH value. The reaction is conducted in the reaction mixture, thereby producing 2,2'-diamino-azobenzene, and the absorbance increase at the maximum absorption wavelength of the produced 2,2'-diamino-azobenzene is measured.

In a variably operated valve apparatus of an internal combustion engine and a start control apparatus of the same engine, the internal combustion engine being equipped with a crank position control mechanism by means of which a stop position of a piston is controllable at a time of an engine stop and the variably operated valve apparatus being capable of variably controlling at least a closure timing of an intake valve, the closure timing of the intake valve is placed at a first position which is more advance angle side than the stop position of the piston of one of engine cylinders in a compression stroke and which is stop controlled by means of the crank position control mechanism and one of the remaining cylinders which is in a suction stroke has its the intake valve open, at the time of the engine stop.

In an automatic gain control circuit, a peak detection circuit detects and outputs the peak voltage of an output signal from a variable gain circuit. An average value detection/output amplitude setting circuit detects the average value voltage of an output signal from the variable gain circuit, and outputs a calculated voltage. An amplification circuit controls the gain of the variable gain circuit by amplifying the difference between the output voltages of the peak detection circuit and average value detection/output amplitude setting circuit. The number of base-emitter junctions of transistors on a path in the peak detection circuit from input ports which receive output signals from the variable gain circuit to an output port which outputs a voltage to the amplification circuit is equal to the number of base-emitter junctions of transistors on a path in the average value detection/output amplitude setting circuit.

An electric vehicle includes: a motor to propel the electric vehicle; a secondary battery that exchanges power with the motor via a power line; a capacitor that is connected to the power line; a collision detection unit that detects a collision of the electric vehicle; a rotation speed detection unit that detects a rotation speed of the motor; and a control unit that, when a collision of the electric vehicle is detected and the detected rotation speed of the motor equals or exceeds a predetermined rotation speed, controls the motor such that the rotation speed of the motor falls below the predetermined rotation speed and then executes discharge control to discharge the capacitor.
摘要:
A controller of a variable valve device is configured to, before starting an internal combustion engine, set an operation angle varying mechanism to control an intake valve of the engine to have such an operation angle as to retard a valve close timing of the intake valve relative to a piston bottom dead center; define a given period from a instruction time when an instruction signal is fed to the controller for starting the engine to a time when a combustion of air/fuel mixture is actually commenced in the engine; and when, in the given period, a temperature representing the temperature of the engine is lower than a predetermined temperature, reduce the operation angle of the intake valve so as to bring the valve close timing of the intake valve near to the piston bottom dead center.

The present invention relates to a thermoplastic resin composition which comprises 100 parts by weight of a thermoplastic resin (component A) and 1 to 400 parts by weight of a granular inorganic filler (component B) comprising an inorganic filler having an average particle diameter of 0.01 to 100 μm and a water-soluble polyester resin binder, and having a bulk density of 0.4 to 1.5 g/mL; and a resin molded article obtained by molding the thermoplastic resin composition. The thermoplastic resin composition is improved in various properties such as extrusion moldability, rigidity, impact resistance, thermal stability and hue, and exhibits an excellent balance between these properties.
摘要:
A parking assist device has a touch display (58) including a display unit for displaying a situation around a vehicle and an input unit for entering a target parking position of a vehicle, and also has a control device (60) performing parking assist control by calculating a path according to the target parking position. The control device (60) further performs, under a predetermined condition, assist control for position alignment of a vehicle-side power transmission/reception unit placed on the vehicle with an apparatus-side power transmission/reception unit of an apparatus placed on a ground. Preferably, the parking assist device further has a back monitor camera (53) for taking an image of a surrounding situation of the vehicle. When an identifier indicating the apparatus-side power transmission/reception unit is present in the vicinity of the target parking position in the taken surrounding situation, the control device (60) recognizes the position of the identifier and performs the position alignment assist control.
