摘要： While a control portion (26) changes the laser power stepwise with a laser power control portion (4), the optical disk apparatus of the present invention compares a predetermined level with an output by a detector (24) that detects the correlation between a pattern to be recorded on the optical disk and the reproduction signal of the recording pattern detects as the minimum recording power the recording power when the originally smaller of the predetermined level and that output by the detector becomes larger than the other, and sets the optimum recording power to a power obtained by multiplying the detected minimum recording power by a certain factor.

摘要： A method and an apparatus for producing an optical element, e.g. of glass or plastic, capable of performing a molding temperature control required for a plurality of independent molding blocks (11) in a short period of time, and continuously and simultaneously producing a plurality of different optical elements having a high degree of accuracy at a low cost by press-molding is provided.
The temperature control (27) acts on heaters (7) provided in upper and lower plates (27) of each heating and cooking section (3-6). The plates (27) exchange heat with the molding block (11), enclosing the material to be molded (17), by contact. The plates (27) are provided with means (8), such as a WC-based coating, on the surface which contacts the molding block (11) for rendering temperature uniform across the plate mold contact surface.

摘要： Data read from an optical disk includes address period, ALPC period and data period, in which the ALPC period contains no-signal state at opposite ends of laser output signal. An ALPC period detector is provided for detecting the ALPC period. During the ALPC period, an automatic gain control circuit is suspended to hold the gain to the predetermined value. Alternatively, during the ALPC period, the signal applied to the automatic gain control circuit is reduced to ground level or attenuated. Thus, since the automatic gain control circuit will not be adversely affected by the laser output signal and no-signal state in the ALPC period, the automatic gain control circuit will amplify the signal in the data period with an appropriate gain.

摘要： Light radiated from a light source 1 is gathered by an oval mirror 2. The gathered light is incident on one end of a rod-shaped optical integrator 3, integrated and made uniform within the optical integrator 3, and is radiated from the other end of the optical integrator 3. The light 10 from the optical integrator is diffused and projected on an exposure area 6a of a display tube by a lens system 7. The lens system 7 presents astigmatism, thereby forming a first virtual focus and a second virtual focus on its virtual image area. The diffused light is apparently diffused vertically at the first virtual focus and diffused horizontally at the second virtual focus. The foregoing first vertical focus and second vertical focus correspond in position to the positions of the vertical deflection means and horizontal deflection means of this display tube.
Therefore, the directions of the exposure light beams to shed light on G, B and R dots are in agreement with the directions of the deflected electron beams.
As a result, the above deflected electron beans can sweep over the G, B and R dots accurately in synchronization with image signals.

摘要： In forming a plano-convex lens from a column-like lens blank by heating the blank to a temperature higher than the transition temperature thereof and by pressurizing an upper die with a closed space formed between the blank and the upper die, there are alternately repeated operations of pressurizing the upper die and stopping the application of pressure thereto. Through the control of the amount of displacement of the upper die, the maximum pressure of gas in the closed space at each pressurizing step is so controlled: to be sufficiently low with respect to the surface viscosity of the blank such that no local concave deformation in the surface of the blank is produced; and to be sufficiently high such that gas caught in the closed space is discharged during each step of stopping the application of pressure.
