摘要： A hydraulic auto-tensioner includes a cylinder containing hydraulic oil, a rod inserted in the cylinder, and two coupling pieces mounted to the bottom of the cylinder and the top end of the rod, respectively. A support ring is inserted in the mounting hole of each coupling piece, and a bush is inserted in the support ring. One of the radially inner surface of the mounting hole and the radially outer surface of the support ring is a curved surface such that the support ring is alignable. Radially outwardly extending flanges are formed at one end of the support ring and at the other end of the bush such that the flanges axially face the respective end surfaces of the coupling piece with gaps left therebetween. A coupling arrangement is provided between the support ring and the bush which is adapted to engage both the support ring and the bush when the bush is inserted into the support ring, thereby axially inseparably coupling them together.

摘要： In the case that periodical transmission of transmission signal number-of-sequence quality indicative signal cannot be performed, the number of transmission signal sequences is clarified in association with reception quality information that is generated immediately after the case, and the base station apparatus performs appropriate communication resource allocation. A mobile station apparatus has a feedback information control section 65 that generates feedback information including reception quality information, transmission signal preprocessing information and transmission signal number-of-sequence information, and a radio transmission section 51 that periodically transmits the generated feedback information to the base station apparatus, where when the radio transmission section 51 does not transmit the transmission signal number-of-sequence information with communication resources periodically allocated from the base station apparatus so as to transmit the transmission signal number-of-sequence information, the radio transmission section 51 transmits the transmission signal number-of-sequence information to the base station apparatus with communication resources enabling transmission of the feedback information allocated from the base station apparatus subsequently to the communication resources.

摘要： When transmission of a downlink signal is to be performed in sub-frame 5, at this point, no feedback of reception quality information and transmit signal pre-coding information in mode 2, which would be covered by transmit signal pre-coder confirmation, has been performed. Therefore, information on the pre-coding that has been applied to all assigned resources is transmitted by being added to a downlink control signal (353). In sub-frame 9, a downlink signal is transmitted, and transmit signal pre-coder confirmation is added thereto. With respect to this case, the mobile station apparatus determines that the downlink signal has been pre-coded using the transmit signal pre-coding information transmitted in sub-frame 8, and demodulates the received signal with it. Sub-frame 12 represents a case where downlink data is transmitted by assigning sub-band 7. In so doing, it is preferable that the base station apparatus use the reception quality information and transmit signal pre-coding information for sub-band 7 reported in sub-frame 10. Accordingly, the base station apparatus transmits to the mobile station apparatus the transmit signal pre-coding information obtained in sub-frame 10 by explicitly including it in downlink control information (358). Thus, in cases where there exist a plurality of modes for transmitting transmit signal pre-coding information, it is possible to solve the problem where information whose priority should be high is readily overwritten by information of low priority.

摘要： A chain tensioner for use with a chain of a vehicle engine, includes a housing and a plunger slidably mounted in a cylinder chamber formed in the housing. The plunger is biased outwardly by a return spring mounted in a pressure chamber defined in the cylinder chamber by the plunger. A check valve is provided in the cylinder chamber to prevent backflow of hydraulic oil in the pressure chamber. A relief valve, provided in the plunger, opens above a relief pressure, thereby discharging hydraulic oil in the pressure chamber. An oil leakage clearance is defined between the plunger and the inner wall of the cylinder chamber. The relief pressure and the oil leakage clearance dimension are determined such that the tension in the chain is kept at such a level that vibrations of the chain are minimum at any temperature of hydraulic oil and at any engine revolution speed.
