    摘要： A method of magneto-optical recording and overwriting information onto a double-layer magneto-optical recording medium which has laminated first and second magnetic layers having different coercive forces at a lower operation temperature and a higher operation temperature of which one is a recording operation temperature and the other is an erasing operation temperature, without using an initializing external magnetic field. The method includes the steps of recording by applying a laser beam to an area of the recording medium at a power level corresponding to one of these operating temperatures and erasing by applying a laser beam to an area of the recording medium at a different power level corresponding to the other of the operating temperatures, while applying a bias magnetic field to the magneto-optical recording medium with the same magnetization direction during both recording and erasing, the intensity of the bias magnetic field being greater than the coercive forces of the first and second magnetic layers at the lower operation temperature.

    摘要： In a distributor type fuel injection pump and a power transmission pump for transmitting power to the fuel injection pump, when a rotation system member of the injection pump is seized if anything should happen, only an injection pump is damaged to thereby greatly reduce damage to an engine. To this end, an annular groove is provided in a rotor to which power from the engine is transmitted, and the annular groove constitutes a frail portion of the rotor. The annular groove is positioned along the rotor so that all or most of the sliding portions of the rotor are located on a side of the groove opposite to a power supply side. When seizure occurs in the sliding portions of the rotor to prevent rotation, the rotor is twisted off at the annular groove by the power from the engine, so that rotation of a power supply side portion of the rotor is not prevented.

    摘要： A method and apparatus for recording information on a magnetic recording medium with high density is provided. A heat spot of predetermined area is applied to the recording medium to raise the local temperature of the recording medium where the heat spot is applied above the Curie point of the recording medium. The heat spot is moved along the recording medium and a magnetic field is applied when a part of the recording medium heated by the heat spot is in the neighborhood of the Curie point in its cooling process, thereby recording information on the recording medium. In accordance with the present invention, an element or bit of information to be recorded on the recording medium is formed by a portion of the heat spot; thus, it relaxes recording conditions and allows to increase recording density.

    摘要： In an inner cam type injection pump, the side surface of the protruding portion of each of the plungers facing the compression space is formed in a projecting shape in the area where the plunger changes from the base end side into the front end. Specific forms of the projection include a structure constituted with slanted surfaces over a plurality of stages with different inclinations relative to the axis of the plunger, an arc form and a structure provided with a overhanging portion formed on the side surface of the protruding portion, which does not overhang the base end, projecting out from the side surface. This will prevent collision at the shoulder portion of the plunger and, consequently, prevent the deformation at the shoulder portion and ensures that plungers will not have sliding failures or become seized. Even when plungers collide, the sliding of the plungers will not be affected, ensuring that plungers do not have sliding failures or become seized.
