摘要： A magneto-optical recording device for radiating a laser beam according to recording information onto a magneto-optical recording medium having an easy axis of magnetization in a direction perpendicular to a film face of the recording medium itself to form a reversed domain and record information, which forms a reversed domain by radiating a laser beam and moves the position of the reversed domain to record information. In an embodiment of the present invention, it becomes possible to over-write new information without erasing beforehand information already recorded by only controlling the intensity, pulse width, radiation position and radiation time of the laser beam without providing a special bias magnetic field for reversing the magnetic field.

摘要： A method of recording information by changing a recording medium through irradiation with an energy beam such as a light beam, electron beam or the like. A single pulse or a plurality of pulses are employed for forming recorded dots. The pulse has a pulse width shorter than a time required for the center of energy beam spot to move from one to other end of the dot upon recording thereof. By virtue of the possibility of reversible change even in a recording film susceptible to high rate speed of change, the rate of information transfer can be increased. Over-write recording can also be accomplished with the single laser beam. An increased amount of information can be handled in the recording and reproduction.
摘要翻译：通过用诸如光束，电子束等能量束的照射改变记录介质来记录信息的方法。单脉冲或多脉冲用于形成记录点。脉冲的脉冲宽度短于在记录时能量束点的中心从点到另一端移动所需的时间。由于即使在容易受高速率变化的记录膜影响的情况下也可能发生可逆变化，所以可以提高信息传送速度。也可以用单个激光束实现写入记录。在记录和再现中可以处理增加的信息量。

摘要： A magneto-optical data recording system includes magnetic field pulse applying apparatus for applying to a magneto-optic recording medium a magnetic field pulse of a polarity corresponding to code data to be recorded, and a heating apparatus for heating the recording medium in a pulsating manner at a predetermined frequency synchronous with the code data to be recorded. During recording, the magnetic field pulse applying apparatus applies a magnetic field pulse of a polarity corresponding to code data along a track of the recording medium and the heating apparatus continuously heats the recording medium in a pulsating manner at a predetermined frequency synchronous with the code data to thereby directly overwrite the code data. The magnetic field pulse applying apparatus includes a magnetic coil driven by code data from a source of code data (data generator). The heating apparatus includes an optical head which comprises a source of laser beam driven by a laser driver and an optical system which focuses the laser beam from the source of laser beam as a small light spot onto the recording medium.

摘要： A numerically controlled grinding machine provided with an angular type grinding wheel and a numerical controller for controlling the feed of grinding wheel based upon a control signal from a measuring head which measures the diameter of a cylindrical side of a workpiece. The grinding wheel is moved along an inclined path to grind the cylindrical side and a radially inner portion of the shoulder of the workpiece, simultaneously. In response to the control signal from the measuring head, the feeding of the grinding wheel is stopped. Then, the numerical controller detects the difference between a target position and a actual position of the grinding wheel along an axis of a work spindle. Further, the numerical controller compensates another target position to grind the radially outer portion of the shoulder for the difference. Thereafter, the grinding wheel is moved to the compensated target position so as to grind the radially outer portion of the shoulder.

摘要： A method and an apparatus for continuously annealing cold rolled steel strips successively passing through a preheating zone, a low temperature heating zone, a high temperature heating soaking zone, a primary cooling zone and a secondary cooling zone. In each zone, the steel strip is driven by hearth rolls alternately upward and downward in a serpentine path. According to the invention, in a high temperature zone such as the high temperature heating zone and the primary cooling zone where the steel strip is prone to heat buckling, the steel strip is caused to pass only once in a single direction without passing along the serpentine path, thereby preventing meandering and heat buckling of the steel strip.
