    • To reduce operational and management costs during normal operations while recovering a database without loss and maintaining on-line performance on a site. A first system includes a primary storage system (103) that stores a DB (107) and a main computer (100) that executes a primary DBMS (101), which provides a DB. A second system includes a secondary (113) that receives from the primary storage system (103) a copy of a log, which shows update differences of the DB (107), and stores a secondary DBMS (117), and a subset (500) that recovers the secondary DB (117) according to the log that is copied from the primary storage system (103). When a failure occurs in the first system, the first system is switched to the second system. A second computer (110) that executes a second DBMS (111) is added to the second system, and the secondary DB (117) that is recovered or is being recovered in the subset (500) is taken over to the second computer (110).

    • In the negative pressure booster, when in operation, a reaction disc (35) deflects due to the reaction from an output shaft (34) and pushes a pin (28) backward, and the pin (28) pushes a vacuum valve seat member (21) backward via an arm (25). Thereafter, the vacuum valve seat member (21) pushes up a valve body (15) backward via a vacuum valve portion (17), and an atmosphere valve portion (16) moves backward relative to a valve body (4). The stroke of an input shaft (11) is shortened by an amount an atmosphere valve (20) and a vacuum valve (23) have moved backward. As the valve body (15) is pushed up backward, further, a balance position for the atmosphere valve (20) and the vacuum valve (23) shifts backward depending upon the output (input). Therefore, the stroke of the input member is shortened at the time of producing a large output.
    • 在负压增压器中,当操作时,反作用盘(35)由于输出轴(34)的反作用而偏转并向后推动销(28),并且销(28)推动真空阀座构件 21)经由臂(25)向后延伸。 此后,真空阀座构件(21)通过真空阀部(17)向上推动阀体(15),并且气氛阀部(16)相对于阀体(4)向后移动。 输入轴(11)的行程被大气阀(20)和真空阀(23)向后移动的量缩短。 随着阀体(15)向后推,另外,大气阀(20)和真空阀(23)的平衡位置根据输出(输入)而向后移动。 因此,在产生大输出时,输入构件的行程被缩短。

    • A recording apparatus including a recording unit that performs recording on a recording medium; a transporting unit capable of transporting the recording medium; a first guide member and a second guide member disposed facing the first guide member having an section of a transport path of the recording medium disposed therebetween; and an optical sensor including a light-emitting portion and a light-receiving portion and having an optical axis that traverses the transport path of the recording medium between the first and second guide members. At least one of the light-emitting portion and the light-receiving portion projects from an outer side of the transport path towards the first guide member. The first guide member has a cutout having an opening where the light-emitting portion or the light-receiving portion is disposed. The opening is covered with a sheet member except for an area where the optical axis of the optical sensor extends.
