The pressurized water reactor according an embodiment comprises: a cylindrical reactor pressure vessel (1) to which inlet nozzles are connected; fuel assemblies which are contained within the reactor pressure vessel (1); a cylindrical reactor core barrel (3) which surrounds the fuel assemblies and forms an annular downcomer (6) between the reactor core barrel (3) and the inner surface of the reactor pressure vessel (1); and radial supports. The radial supports are supports which are arranged below the downcomer (6) at intervals in the circumferential direction, each has vertical flow path formed therein, and position the reactor core barrel (3) and the reactor pressure vessel (1). The radial supports each has, for example, a flow path-equipped radial keys (21) and a key groove member (40).
Abstract:
Provided is a method of producing hydroxyalkylcellulose microparticles, the method including generating a pulse shock wave, and supplying a hydroxyalkylcellulose aqueous solution to the pulse shock wave generation region, thereby crushing and drying the hydroxyalkylcellulose aqueous solution. According to the production method, hydroxyalkylcellulose microparticles having a volume-average particle size of at least 0.1 μm but less than 15 μm are obtained. By mixing the hydroxyalkylcellulose microparticles with a principal agent and subjecting the resulting mixture to a tablet compression, a solid preparation having excellent tensile strength and disintegration properties can be obtained.

A sensor control circuit unit (1) includes a circuit board (70) which has opposite sides (70a) and (70b) facing in parallel with each other, and carries a signal detection circuit (28) for receiving a detection signal whose level is equal to or less than one μA and which changes in accordance with NOX concentration, a power supply circuit (35), and a heater circuit (40) for controlling a heater. The power supply circuit (35) and the heater circuit (40) are mounted on one side of the circuit board (70) toward one side (70a) of the opposite sides, and the signal detection circuit (28) is mounted in a mounting area on the other side of the circuit board (70) toward the other side (70b) of the opposite sides, the mounting area being different from a mounting area of the circuits (35) and (40). A ground conductor (24x) connected to the ground is continuously formed on a surface of the circuit board (70) on which the signal detection circuit (28) is mounted such that the ground conductor (24x) extends along at least the other of the opposite sides.
Abstract:
It is an object of the present invention to provide molecular compounds useful in the fields of state-of the-art materials, such as formulations, waste water treatments, energy transducers, conductors and bio-model reactions, in a way that interaction points and forces working inside polymer assemblies are fixed as well as controlled so that constituent polymers are aligned and modified. It is also an object of the present invention to provide methods for aligning and/or modifying polymers having hydrogen bond sites. A molecular compound is produced from a tetrakis aryl compound represented by Formula (I) (wherein, X is (CH2)n, or p-phenylene; n is 0, 1, 2 or 3; Y is hydroxyl, carboxyl or optionally substituted amino: and R1 and R2 are each hydrogen, lower alkyl, optionally substituted phenyl, halogen or lower alkoxy) and a polymer having hydrogen bond sites, such as polyethers, polyalcohols or polyamines.
Abstract:
In a sensor control apparatus (2), a GND1 terminal for signal-system circuits and a GND2 terminal for a power-system circuit are separately provided in an external circuit terminal section (31). The ground for the drive circuit of the power system and the ground for the drive circuits of the signal system are disposed independently of each other on a circuit board (20). Further, a first electrical path for connecting the circuit board (20) and an engine control unit is provided independently of a second electrical path for connecting the circuit board (20) and a battery. Therefore, even when a heater control circuit (28) is turned ON, the influence of heater current on an Ip1 cell/Vs cell control circuit (26), an Ip2 cell control circuit (27), and a CAN (Controller Area Network) circuit (29) can be suppressed. Further, since the ground for the sensor-system circuit and the ground for the CAN circuit (29) are rendered common, the layout of the ground wring can be simplified.
