An impact tool includes: a spindle disposed in a housing; an anvil disposed in front of the spindle and rotatably supported by the housing through a metal bearing, a rear surface of the anvil having a bearing hole in which a front end of the spindle is received; an impact mechanism configured to transmit a rotation of the spindle to the anvil; an outer groove formed on an outer periphery of the anvil and opposed to the metal bearing; and a connecting opening radially extending in the anvil and connecting the bearing hole and the outer groove to provide a communication therebetween. The outer groove is formed to have a depth in the range of 3-10% of an outer diameter of the anvil, and the connecting opening opens at a rear end of the outer groove in an axial direction of the anvil.

An information collection device acquires information from a plurality of devices connected through a network. The information collection device includes: a first addition unit that adds, for each of the devices, an information collection duration required to collect information of the devices to a communication duration required to communicate with the devices; a second addition unit that adds a maximum duration among the durations by addition of the first addition unit to a predetermined time to obtain a first time; a subtraction unit that subtracts the information collection duration of each of the devices from the first time; a first setting unit that sets a time obtained by the subtraction unit as a second time that is when information collection starts at each of the devices; and an acquisition unit that acquires information obtained by the information collection that starts at the second time.

An information processing apparatus obtains, from an F-CMDB for managing CIs regarding resources and their attribute values, CIs with the type and attribute of the resource for which a rule is to be created for use at the time of comparison between CIs. From the F-CMDB for managing CIs of SRC and CIs of DST, and relations between SRC and DST together, the information processing apparatus also obtains CI pairs with SRC including any CI previously obtained and also having a relation corresponding to the determination objective of the rule. Then, the information processing apparatus subjects CIs of SRC with the same classification as that defined in a CI of DST to grouping. Then, the information processing apparatus stores a group of CIs of SRC obtained through grouping in a rule DB as a rule for the determination objective.

Disclosed is an immersion nozzle, which comprises a vertically-extending pipe-shaped straight nozzle body 10 adapted to allow molten steel to pass downwardly from an inlet port 9 provided at an upper end thereof, and a pair of discharge portions each including a respective one of a pair of outlet ports 12 provided in a lower portion of the straight nozzle body 10 in a bilaterally symmetrical arrangement and adapted to discharge molten steel laterally from a lateral side of the straight nozzle body. Each of the discharge portions has an inner surface defining the outlet port 12 and extending parallel to an axis of the outlet port 12 to define a length of the discharge portion at 45 mm or more. A ratio of S1/S2 is in the range of 0.8 to 1.8, wherein S1 is a total transverse vertical cross-sectional area of the outlet ports, and S2 is a cross-sectional area of an inner hole of the straight nozzle body taken along a plane including a line connecting respective inwardmost and uppermost positions of the outlet ports and extends perpendicularly to an axis of the straight nozzle body. The axis of the outlet port extends laterally outwardly and downwardly at the following angle θt with respect to a horizontal direction: 0°≦θt≦20°. The immersion nozzle of the present invention can suppress deceleration of a molten steel flow discharged from the outlet port to obtain a flow speed in an intended direction over a maximized distance.

To provide an actuator capable of positioning a spherical body in a predetermined position without causing significant blurring of a formed image. The present invention is an actuator for moving an imaging lens to prevent blurring of an image, comprising a fixed portion (12); a movable portion (14) attached to the imaging lens; a plurality of spherical bodies (18) sandwiched between the movable portion and the fixed portion, supporting the movable portion; a drive means; fixed portion drop prevention walls (50) and movable portion drop prevention walls (54), erected so as to respectively surround each of the spherical bodies and prevent the spherical bodies from dropping; fixed portion contact walls (52) and moving portion contact walls (56) formed contiguously with these drop prevention walls such that when the movable portion is moved to a predetermined locking position, the spherical bodies contact it; and a control means (36) for moving the movable portion to a locking position by rotating the movable portion around the optical axis, thereby positioning each of the spherical bodies.
