    • In track jumping or focus jumping in an optical recording and reproducing apparatus for an optical disk, a light beam is accelerated and decelerated from a track to an adjacent one or from an information plane to an adjacent one in the optical disk. A moving time of light beam under acceleration to an adjacent track or information plane for jumping is measured from the start of acceleration to a predetermined point according to tracking o focus error signal. Then, the deceleration signal for tracking or focus actuator is changed on amplitude or period according to the measured period. Thus, track or focus jumping can be performed stably against external disturbances. Alternatively, the light beam is forced to be driven until the level of the tracking or focus error signal is decreased below a predetermined value after the output of the deceleration signal is completed.
    • 在用于光盘的光学记录和再现装置中的轨道跳跃或聚焦跳跃中,光束从光盘到光盘加速和减速到相邻的一个或从信息平面到相邻的一个。 根据跟踪o聚焦误差信号,从加速开始到预定点测量加速下的光束到相邻轨迹或信息平面的移动时间。 然后,跟踪或聚焦致动器的减速信号根据测量周期在幅度或周期上改变。 因此,可以针对外部干扰稳定地执行跟踪或聚焦跳跃。 或者,在完成减速信号的输出之后,迫使光束被驱动直到跟踪或聚焦误差信号的电平降低到预定值以下。

    • A large number of microscopic recess portions are formed on a surface of a glass substrate in a single dimension or two dimensions by conducting a wet etching through a mask. The large number of microscopic recess portions are aligned densely by again conducting the wet etching but not through the mask. A separating agent is applied upon the surface of the glass substrate and a light-curable or heat-curable resin material of high refractive index is applied thereon. The high refractive index resin material is cured, after piling a first glass substrate upon the high refractive index resin material so as to extend the high refractive index resin material thereon. The high refractive index resin material which is cured and the first glass substrate are separated from the glass substrate, and a low refractive index resin material is applied on the high refractive index resin material which is cured on the first glass substrate. The low refractive index resin material is cured, after piling a second glass substrate on the low refractive index resin material so as to extend the low refractive index resin material thereon.

    • The improved illuminating comprises a spheroidal mirror, a light source, a spherical mirror and a condenser lens. The spheroidal mirror has such a shape that it is deficient of a portion that would otherwise reflect light that illuminates any portions other than the object to be illuminated, and that the light from the light source which is directed toward said missing portion is reflected by the spherical mirror positioned on the rear side of said missing portion as seen from the light source and makes another reflection by that part of the spheroidal mirror which faces away said missing portion, thereby illuminating the object. The light source is positioned at the first focal point of the spheroidal mirror in such a way that it faces the mirror, and the spherical mirror is positioned in such a way that its reflecting face lies at the second focal point of the spheroidal mirror. An open window for the exit of light beams is provided in the spherical mirror at a position near the second focal point of the spheroidal mirror, and the condenser lens is provided further ahead of the open window (closer to the object to be illuminated).

    • In an ultrasonic washer for washing by splaying washing toward an object to be washed or a portion to be washed from a front end of a nozzle, a part of an ultrasonic wave propagation member connected to an ultrasonic transducer is protruded into a cavity of the nozzle into which the washing is filled in order to propagate ultrasonic vibration generated by the ultrasonic transducer to the washing efficiently. Furthermore, the ultrasonic wave propagation member is formed so that a cross-sectional area becomes gradually smaller as approaching to the front end thereof, so that the ultrasonic vibration is converged to the end face of the ultrasonic wave propagation member. Still furthermore, a length of the ultrasonic transducer and the ultrasonic wave propagation member is made to be integral multiplication of a half-wavelength of ultrasonic standing wave oscillation, and the end face of the ultrasonic wave propagation member from which the ultrasonic wave is emitted to the washing is disposed at a position of antinode of the ultrasonic standing wave oscillation where the amplitude becomes the largest.
