Title: Optical recording medium
Inventor: ONO YUZO
IPC: G11B7/24
Filed: 1986-10-23
Abstract: PURPOSE:To improve a signal/noise ratio to obtain a high-reliability optical recording medium, by a method wherein the grating surface of an irregular- surface grating consisting of a thermoplastic resin with a period smaller than the wavelength of a light is covered with a metal film. CONSTITUTION:A thermoplastic resin substrate 1is provided with pregrooves 5 for tracking and an irregular-surface grating 3 with a period of 0.3mum smaller than the wavelength of a light is formed on the surfaces of the groove 5 and lands 6. The surface of the irregular-surface grating 3 is coated with a gold film serving as a metal film 2. The writing of a pit 4 eliminates the irregular- surface grating 3. The high-density irregular grating can be easily formed by the recording of a two-beam interference pattern of a laser beam on a photo resist. Since the irregular-surface grating formed on the photo resist can be molded by nickel electroforming, the production of the substrate can be easily performed at a low cost by the use of injection molding or 2P method (photo- setting resin method) similarly to that of a conventional optical disk substrate.

Title: Signal amplifier
Inventor: NAKAYAMA MASASHI
IPC: H04B1/04
Filed: 1992-09-24
Abstract: PURPOSE:To prevent the deterioration of a line quality or the transmission of an excess output even when an input level is not within a normal range by making the input signal level detection range of an input signal level detecting part smaller than an output signal level detection range. CONSTITUTION:When any abnormality is generated, and an input level is decreased, an output level is also decreased. For example, when the input level is turned to a value A, the output level is turned to a value B, and the value A is less than the lower limit value C of an input signal level detection range WIDET. Then, an input signal level detecting part 11 transmits the input side detection data of the value C to a level comparing part 16. On the other hand, an output signal level detecting part 15 transmits the output side detection data of the value B to the comparing part 16. The comparing part 16 compares the data C with the data B, judges that the output level is decreased only by the value D-B, and controls a variable attenuating part 13 so that the output level can be the value D. Thus, even when the input level is deteriorated, the value D can be outputted as the output level, and the decrease of the output level can be prevented.

Abstract: PROBLEM TO BE SOLVED: To eliminate the dazzle of the flash light from a flash light source by inhibiting the flash light from being emitted directly from the flash light source by a light shield plate. SOLUTION: A trapezoidally-sectioned projection window type light transmission part 4 which has an uneven surface 4a is fixed to the opening part at the upper center part of a front housing 3. In a rear housing 2, a reflecting plate 5 consisting of a circuit board is arranged, and the flash light source 6 is fitted to the nearly center front part of the reflecting plate 5. Further, the light shield plate 7 which can be moved to the right and left is arranged between the flash light source 6 and light transmission part 4 in the front housing 3. The flash light from the flash light source 6 is reflected by the light shield plate 7 into inward leak light, which is reflected by the reflecting plate 5 and then emitted outward through the light transmission part 4.  The reflected light which is emitted to the outside is not the flash light directly from the flash light 6, so this reflected light is not dazzling even when viewed outside.
