A bolt-axial-force measuring method and instrument capable of easily and precisely measuring an axial force of a bolt are provided. The bolt is screw-joined and coupled to a piston of a bolt tensioner, and a hydraulic pressure is supplied to its pressure chamber so that the bolt is elongated by applying a tensile force equal to or more than a necessary bolt-fastening force. A nut separating from a fastened member due to the elongation of the bolt is seated again on the fastened member, and the hydraulic pressure in the pressure chamber is discharged to release the tensile force of the bolt. A pressure change of the pressure chamber from which the hydraulic pressure is discharged is detected by a pressure sensor, a point where a change rate of the pressure change detected by a measuring apparatus is suddenly reduced is detected as an inflection point, and a pressure value of the pressure chamber at the inflection point is multiplied by a pressure receiving area of the pressure chamber, whereby the axial force of the bolt is calculated.

In a laminated ceramic capacitor, a cylindrical ceramic part of its ceramics includes, in a manner not exposed to the surface of the ceramics, a cylinder-shaped high-void-ratio part which has a void ratio higher than the void ratio in the cylindrical ceramic part other than the hjigh-void-ratio part and which has two layered parts facing the left and right sides of each layered conductor, respectively, as well as two layered parts facing the outer surfaces of the two outermost layered conductors, respectively. The laminated ceramic electronic component inhibits cracking of its sintered chip.

Automatically preparing communications for transmission by a mobile terminal device. In one example, this includes storing contact information including personal contacts and associated address and face image information. A face image is extracted from within a still image content to obtain an extracted face image. The extracted face image is linked to a given personal contact among the personal contacts by finding a match corresponding to the extracted face image among previously extracted face images found in the stored contact information. The given personal contact is correlated to address information using the contact information, and a message is automatically prepared for transmission to the given personal contact using the address information.

Provided is a fuel cell system that can change the number of active phases in a DC/DC converter in order to prevent overcurrent from flowing through one point (e.g., a reactor of the DC/DC converter) in the system. In step S1, whether or not the system is in a state that causes a rapid change in a voltage command value is checked. If the system is in a state that causes a rapid change in the voltage command value, the processing goes to step S2, and if not, the processing goes to step S3. In step S2, a DC/DC converter is prohibited from being driven in a single phase and the processing ends. In step S3, the DC/DC converter is permitted to be driven in a single phase and the processing ends.

It is possible to suppress vibration of a rotary machine in a rotary machine control apparatus. A drive control system of a fuel cell vehicle having a rotary machine includes a control unit having: a drive permission power calculation module which calculates the rotary machine drive permission power according to the states of a fuel cell and an accumulator as power sources of the rotary machine: a limit torque calculation module which calculates a limit torque of the rotary machine according to the drive permission power; and a filter processing module which performs a low-pass process on the limit torque calculation. A storage device of the control unit stores a filter processing region map indicating the region where the filter process is executed by correlating the region with the drive permission power and the rpm.

A fuel cell system includes a fuel cell, a secondary cell, a voltage transformer, and a control portion. The control portion charges the secondary cell with surplus electric power at the time of starting the fuel cell, and adjusts voltage of the fuel cell between an open-circuit voltage and a high-potential-avoiding voltage in the case where the secondary cell is expected to become overcharged while the output voltage of the fuel cell is decreased from the open-circuit voltage to the high-potential-avoiding voltage. The foregoing case is at least one of the case where a passage electric power that passes through the voltage transformer exceeds a secondary cell-charging-purpose permitted-to-pass electric power, the case where the input electric power restriction value for the secondary cell is exceeded, and the case where amount of regeneration by the mover that is charged is not restricted.

It is possible to suppress over-discharge of an accumulator even when the accumulator is in charge-limited state in a fuel cell output control device. A vehicle drive control system including a fuel cell and an accumulator uses a control unit having: an FC output instruction value calculation module which calculates an output instruction value of a fuel cell according to a power required by a rotary machine; a regeneration limit judgment module which judges whether regeneration is limited for the rotary machine; a battery limit judgment module which judges whether charge of the accumulator is limited; and a required power correction module which corrects the required power of the fuel cell when the charge of the accumulator is limited and neither of the fuel cell or the rotary machine generates power, so as to limit discharge from the accumulator.
