摘要:
A boring tool having a tool body (10) which has a pair of chip discharge flutes (11) formed in the peripheral surface thereof. A cutting edge (13) is formed on the edge line where the end relief surface of the tool body intersects the wall surface of each chip discharge flute which faces forwardly as viewed in the direction of the tool rotation. A first margin (15) is provided on the end of the land which is on the trailing side of the flute (11) as viewed in the tool rotation direction, while a second margin (17) is provided on the end of the land adjacent to the heel (16). The lands are provided with recesses (20) in the depths of each of which progressively increase from the first margin towards the second margin. A sub cutting edge (21) is formed on the edge line where the end relief surface meets the wall surface of the recess (20) which faces forwardly as viewed in the direction of the tool rotation.

A drill including a substantially columnar tool body having an axis. The tool body includes a pair of chip ejection grooves formed in an outer peripheral surface thereof. The tool body further includes, in a distal end portion thereof, a pair of cutting edges provided at respective distal ends of the pair of chip ejection grooves and a recess communicating with the pair of chip ejection grooves. The pair of cutting edges have radially inner ends located in positions slightly offset from the axis radially outward, and the recess extends along the axis while passing a gap between the radially inner ends of the pair of cutting edges, and has a bottom surface facing a distal end of the tool body. The bottom surface of the recess includes one slope and another slope. The one slope obliquely crosses the axis in a position aligned with the axis and inclines toward one of the pair of chip ejection grooves as the one slope proceeds to a side near a base end of the tool body, and the other slope crosses the one slope on a side near the distal end of the tool body and inclines toward another of the pair of chip ejection grooves as the other slope proceeds to the side near the base end of the tool body.

A power feeding control apparatus includes a housing for accommodating at least a relay unit which opens and closes power feeding lines, a control circuit for controlling the relay unit, a leakage current detection circuit for detecting leakage current in the electric vehicle and a power supply circuit for generating a control electric power. The apparatus further includes a power source side connector and a vehicle side connector. The leakage current detection circuit includes a zero current transformer through which the power feeding lines extend and is configured to detect leakage current based on unbalanced currents flowing through the power feeding lines. Lead plates constitute a part of the power feeding lines and pass through a central opening of the zero current transformer, and the zero current transformer includes a positioning member molded within the central opening to fix the positions of the lead plates.

An endoscope system has a light source apparatus and an endoscope including an illumination optical system and an objective optical system. At least the objective optical system of the endoscope is provided with an adjustable diaphragm, and in a light path in one of the light source apparatus, the illumination optical system, and the objective optical system, an insertable/retractable filter for observation for special light is provided. The adjustable diaphragm performs a closing operation or an opening operation only when the filter for observation for special light is inserted into the light path.

An electricity feeding control device is provided with an air hole (31c) which is formed by penetrating a part of a peripheral wall of a body (31) constituting a part of a housing case (3). The housing case (3) is provided in its inside with an inner pressure adjusting sheet (5), formed with a breathable and waterproof member, and arranged so as to cover the air hole (31c) from the inside of the housing case (3). The air hole (31c) comprises a long recess (31c2) formed in an outer surface of the body (31), a communicating hole (31c1) consecutively formed in one end of a longi-tudinal direction of the recess (31c2) and communicated with an inner surface of the body (31), and a shielding plate (33) attached in the outer surface of the body (31) so as to cover a region other than the other end of the longitudinal direction of the recess (31c2), in a region of an opening section (31c3) of the recess (31c2). That is, a channel of the air hole (31c), led from the inside to the outside of the housing case (3), is formed into a nonlinear shape.

摘要:
In order to integrally manage computers and peripheral devices at a user site, when a device monitoring server (203a) receives a trouble message from a device, it sends a message indicating this to a device center server (210) via a router (204). If the received message is a trouble message, the device center server (210) controls an event adapter to convert the received message into a format that a center server can process, and transfers the converted message to the center server (110). Upon receiving the message, the center server (110) displays occurrence of a trouble in an event list using an event monitor (110a). The user can simultaneously monitor the versatile computers and peripheral devices by observing the event monitor.
