Title: Oscillation circuit
Inventor: SATO TOMIO
IPC: H03L5/00
Filed: 1991-09-04
Abstract: PURPOSE:To provide the crystal oscillation circuit capable of increasing the load impedance of the crystal resonator and obtaining the stable oscillation output without deteriorating the crystal resonator Q by making an automatic gain control loop (AGC loop) without inserting the feedback resistance to the crystal resonator. CONSTITUTION:An FET element is inserted as a variable resistance element to the emitter side of an oscillation transistor 12. The gate potential of the FET element before starting the oscillation is zero, and when the oscillation is started, the output of a tuning transformer 13 is taken in the AGC loop, and dc-converted by a rectifier circuit 18. The reverse bias voltage is applied to the gate G of the FET element, increasing the resistance value between the drain and source of the FET element. When the emitter-side resistance value of the transistor 12 becomes high, the emitter-side potential is increased simultaneously. The base current of the transistor 12 is relatively limited, decreasing the gain.

Title: Production of optical recording medium
Inventor: ONO YUZO
IPC: G11B7/24047
Filed: 1985-11-13
Abstract: PURPOSE:To maintain specified quantity of signal light by forming a plastic substrate by using a metallic mold formed from a photoresist film by irradiating interfered laser light to the photoresist film and developing the film and forming a metallic film on the substrate. CONSTITUTION:A photoresist 2 is coated on the substrate 1 and a light beam from a light source is divided to four beams and the beams are collimated to parallel rays of light by collimating lenses 3-6. These parallel rays of the light irradiate the exposing part 11 on the photoresist 2. Interference fringes are thereby formed into a meshed shape and are developed to form the meshed ruggedness of the period substantially smaller than the diameter of recording pits. A nickel film is formed by electroless plating on the meshed pattern surface and is made into a metallic mold by an electroforming method. Plastic is molded by using such mold by which the disk substrate 14 uniformly formed with the meshed pattern 16 is formed. The metallic film 15 is then formed on the pattern 16. The moth eye disk with which the specified quantity of the signal light is made is thus produced.
