摘要:
A drill including a columnar body that is rotated about an axis, a cutting edge that is formed at the tip end of the body, and a thinning edge that is formed continuously with the cutting edge close to the axis of the body, by having a thinning at the tip end of the body. The thinning edge is formed such that a rake angle of the thinning edge relative to the axis of the body changes depending on a location of the thinning edge, where the rake angle of the thinning edge close to the cutting edge is a positive angle larger than that close to the axis of the body.

A shift lever assembly includes a shift lever for shifting a gear position of a transmission, an operated member housed within the shift lever slidably along a longitudinal direction, a shift knob provided at a top of the shift lever for being held by a driver, a knob button coupled with the shift knob for shifting the operated member according to an operation thereof and pivotally supported between a temporarily-held position and an operative position, a cam plate integrally formed on an inside of the knob button, a cam pin provided on the operated member and cooperative with the cam plate, and a boss for holding the knob button at the temporarily-held position by contacting with the cam plate while assembling. The shift lever assembly can have a relatively simple structure and can decrease the number of components. In addition, the shift lever assembly can also improve assembling workability.

A multi-layer photonic network and nodes used therein are provided. The multi-layer photonic network comprises a packet network which performs switching and transfer in packet units, and a photonic network comprising optical transmission lines and photonic switches, and which accommodates the packet network. The multi-layer photonic network also has a two layer structure of optical wavelength links (O-LSPs) and packet links (E-LSPs). The O-LSPs are constituted by the optical transmission lines and comprise optical wavelength switching capability (LSC) which is capable of switching in optical wavelength units and packet switching capability (PSC) which is capable of switching in packet units at both their ends. The E-LSPs include the O-LSPs and PSCs at both their ends. Each node includes a section for automatically establishing an O-LSP according to an establishment request for an E-LSP while taking account of path information including path cost, resource consumption, and traffic quantity.

In a disclosed backup path bandwidth keeping method for keeping bandwidth of a backup path to which an active path is switched when the active path becomes unavailable in nodes of a communication network, each node is connected to the same destination, and the method includes a backup path bandwidth keeping phase, for M (M is a natural number equal to or less than L) channels in L (L is a natural number) channels kept as backup path bandwidth, for notifying a destination-side node existing in a destination side of the backup path of identification number information of the M channels to be kept and identification information indicating that a path for which the bandwidth is to be kept is a backup path.
摘要:
A drill which includes a cylindrical main body and a shank contiguous to each other, and which is to be rotated about an axis of the cylindrical main body in a predetermined rotating direction, for machining a hole in a workpiece. The cylindrical main body has flutes which are formed in the cylindrical main body and extend from an axially distal end portion of the cylindrical main body toward the shank, so as to provide cutting edges in the axially distal end portion of the cylindrical main body. The cutting edges cooperate with each other to define a point angle which is not smaller than 170° and is smaller than 180°. Each of the cutting edges is substantially straight as seen in a direction perpendicular to the axis, or is curved such that each cutting edge is convexed as seen in the direction perpendicular to the axis.

A column shifter has an impact absorbing structure. The column shifter includes a shift lever rotatably supported to a steering column. The column shifter includes a bellcrank supported to the steering column and being rotatable by the shift lever about the rotation center to operate a transmission. The bellcrank includes a first link angularly-displaced by the shift lever. The bellcrank includes a second link separated angularly from the first link about the rotation center. The second link includes a distal end connected to the transmission. The second link includes a strength weakened portion between the distal end and the rotation center.

A shift lever apparatus for an automatic transmission includes first and second levers, which are pivotally supported on the positioning plate by a shaft, and a lock lever, which is pivotally supported by a shaft parallel to the shaft of the second lever. The apparatus also includes a spring for energizing the first and second levers so as to draw the arms of the first and second levers close together and to restrain the positioning pin positioned at the parking position. Even though an actuator is connected to and actuates the lock lever so as to rotate it in predetermined directions, since the lock lever of the arm is pressed by the first lever when the positioning pin is positioned at the parking position, the lock lever can be stabilized under The positioning pin to lock it at the parking position.
