Provided is a tail cylinder attaching and detaching fixture that attaches and detaches a tail cylinder to and from a casing, the tail cylinder being included in a combustor inserted into the casing so that the front end is connected to an inlet portion of a combustion gas passageway, the tail cylinder attaching and detaching fixture including: a guide portion of which the front end is disposed inside the casing and the front end and the base end are respectively supported by the casing and which supports the tail cylinder so as to be movable in the axial direction of the combustor; and an advancing and retracting mechanism that advances and retracts the tail cylinder in the axial direction.
摘要:
A receiver for the CDMA system which reduces power consumption during a suspension period of intermittent receiving operation by monitoring a suspension period by a low-power timer so that a VC-TCXO, reference signal group generation and receiving units are turned off and a modem unit is set to a sleep state. Upon resumption of receiving operation, a high-accuracy timer is started to count a time period and part of a received signal is stored. A PN code phase of stored data is calculated during the time period to obtain an indication value for phase deviation. State vectors for short and long codes and a further reception time are calculated based on the indication value. When the high-accuracy timer counts the time period and produces 0V(d), demodulation operation by a rake demodulation, demultiplexing, and descrambler units is started and is continued during the reception time.

A Power system protection and control system has protection and control terminals that perform protection and control of a power system by operation of a plurality of CBs in response to state variables input from power system; and a power system monitoring and control host mutually connected in a fashion to permit data exchange through a transmission system (communication network) with protection and control terminals and that performs monitoring and control of power system in accordance with data transmitted from protection and control terminals. Protection and control terminals each has a correlation circuit that performs correlation of an operated CB and the cause of its operation, using information sent from protective relay circuit, CB control circuit, re-closure circuit and CB state receiving circuit when at least one of a plurality of CBs is operated, and a correlation result transmission circuit that transmits the result obtained by the correlation processing of this correlation circuit to power system monitoring and control host through transmission system. The power system monitoring and control host includes a correlation result transmission unit that receives and displays the correlation result transmitted through transmission system from correlation result transmission circuit, associated message file storage unit and CB operation display unit.

A mail server and mail terminals are connected through a radio communication network. The mail server makes viral infection decision of if e-mails are infected with computer virus without burdening the mail terminals having poor processing power. The mail terminals are constructed to serve as small-sized mail terminals. When an e-mail arrives at the mail server through the Internet, the mail server decides if the e-mail is infected with virus. The result of the viral infection decision is added as the whole or a part of inspection information within the header of the e-mail. The corresponding mail terminal can detect presence or absence of viral infection on the basis of the inspection information. When the e-mail is infected with virus, the mail terminal can inform a user of the contaminated e-mail by making tone of a buzzer or vibrator different from a normal e-mail.

When a receiving end is a cellular phone, the cellular phone that displays the local time at the receiving end and a base station used in this cellular phone are realized. A time recognition unit that obtains the local time at the receiving end using the time information acquired from the cellular phone of the receiving end or the base station at which the cellular phone of the receiving end is registered in stand-by mode and a display unit that displays the local time are installed in the cellular phone. Further, when the time information or position information of the cellular phone registered in the base station in stand-by mode is requested from the calling end, a unit for sending the time information or position information at the location at which this base station exists to the cellular phone of a requesting source is installed in the base station.
