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： 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.

摘要： A mold comprises a pair of first (1) and second (2) elements each having a molding surface for defining a cavity and a rear surface (1b,2b) being opposite to the molding surface and in contact with a corresponding heater block, and a ring member (3) for guiding the first and second elements. At least one rear surface has a part (5a) which is not in contact with the corresponding heater block. Also, another mold comprises a second ring member made of a material with a lower thermal conductivity than that of the first one at the outside of the first one. A molding method for optical elements is such that a glass with 10¹² poise or more is fed to a mold with a temperature of a glass transition point or less, heated to a temperature corresponding to the glass viscosity 10⁸ to 10¹⁰ poise, pressed for 3 to 90 seconds, then cooled at a cooling rate 1.5 to 2.5°C/sec to 10¹⁰ to 10¹¹ poise and thereafter at a cooling rate 0.2 to 1.5°C/sec with the glass is pressurized, and taken out as an optical element at a temperature of a glass transition point or less.
