A drill capable of suppressing inter-layer peeling (delamination) while keeping hole diameter accuracy even if the number of holed to be worked increases is provided. The drill includes a first flank which has a ridge line forming a cutting edge, a second flank which is adjacent to the first flank and has a ridge line forming a land portion, and a third flank which is adjacent to the first flank and has a ridge line forming a chisel edge. The drill further includes a fourth flank which is surrounded by a ridge line forming the first flank, a ridge line forming the third flank, and a trough line forming the second flank

A cemented carbide end mill has three or more cutting edges formed on its periphery and flutes each provided between adjacent cutting edges. The land width of each cutting edge and the flute width has a ratio of 1:1.5 to 1:4. Each flute has a helix angle of 35°-60° and, when viewed in a cross section perpendicular to the end mill axis, is in a shape smoothly concave radially inwardly. The core of the end mill has a diameter which is 62%-68% of the outer diameter of the end mill. The cutting edges have a base material of ultra-fine cemented carbide and are coated with a titanium-aluminum nitride hard film. The end mill is good at chip discharging in groove cutting and provides less inclination of cut grooves and less corner wear of the end mill.
摘要:
An apparatus for optically recording/reproducing data to/from a disc including a focus servo circuit which initially sets an objective lens of an optical head to a predetermined setting. This predetermined setting is such that a laser beam passing through the lens is focused on the disc at a point inside of the disc in the thickness direction. Then, the focus servo circuit fine tunes the objective lens position until the laser beam is focused onto a recording film located inside of the disc.
摘要:
A laser beam control circuit for an optical recording/reproducing apparatus, which controls the intensity of a laser beam striking a magneto-optical disc. The control circuit controls the injection current to a laser diode to provide high intensity for recording and low intensity for reproducing, providing a smooth transition between the high and low intensity states, and avoiding any excessive transition current. The control circuit monitors the output power of the laser diode and maintains it at a first value in the reproducing mode and a second value in the recording mode, and further controls the output power so that even during switching, the output power does not exceed the second level. This is done by supplying a compensating reference voltage to the recording power control loop during the reproducing mode, so that the output of the recording error amplifier does not change abruptly when the operating mode is switched to the recording mode.

Disclosed is a magneto-optic recording/reproducing apparatus capable of detecting small size defects in a magneto-optic recording disk in the order of tens of microns in size, and capable of reliably compensating for signal defects of a video image recorded on the disk. In the apparatus first and second photodetectors are provided for detecting information signals of two luminous fluxes into which a luminous flux emitted from a laser oscillator is divided by light splitting means. The photodetectors are arranged on the part of light reflected or emitted by the surface of a magneto-optic recording medium when it is irradiated with the luminous flux from the laser oscillator. According to the invention, the signals produced by the photodetectors are processed to produce a highly sensitive defect signal or a plurality of highly sensitive defect signals which may be summed together.

A scan tracking apparatus for a helical scan tape recorder, comprising a movable tape head (11), a detector (13) detecting the envelope of the tape signal to produce a reproduced signal, sampling means (15) for sampling the reproduced signal at fixed points of the helical scan, memory (17) for storing the reproduced signal and correction signals from different tracks of the helical scan, computation means (2) for computing a correction signal to return the tape head to the center of the track, a sawtooth generator (2, 4) for producing a signal related to the tape speed (v), and a head driving mechanism (9) for moving the tape head in response to the sawtooth and correction signals.
摘要:
A spring connector comprises a supporting member, a cylindrical plunger, and a coil spring provided in the cylindrical plunger. The supporting member has a base, a pillar extended from the base, and a shoulder and a head having a diameter larger than that of the pillar. The upper end of the head has an inclined surface. The plunger has a closed upper end, an opening formed in an annular bent portion of a lower end thereof. An annular edge of the opening is slidably engaged with the supporting member at the shoulder thereof. The coil spring is provided between the closed upper end and the inclined surface of the head so that a shoulder formed on the head at a lower annular periphery is pressed against the annular bent portion of the opening.
