Filed: 1996-04-01
Abstract: PROBLEM TO BE SOLVED: To improve read back operation of an optical disc by varying the erasure power level control of laser read power level depending on the radial position of an optical read sensor with respect to the disc. SOLUTION: A laser 14 radiates a beam having intensity determined by an erasure beam intensity profile for reading data and a laser read control 40 operates the laser 14 through a laser control circuit 15 under control of a DAC 23 and varies the read power level being radiated from the laser 14. As a method for operating the equipment automatically, the laser read power level is regulated according to an erasure radius profile establishing the alteration of read beam power level by increasing or decreasing the scanning radius of spiral track on an optical disc 10. The erasure radius profile represents the beam power level at various radiuses for erasing a recorded data. The read beam power level is regulated from a predetermined minimum level (used at the inside diameter of disc) following to the erase diameter profile.

Title: Charge detection circuit
Inventor: FURUYA AKIRA
IPC: H04N5/335
Filed: 1987-03-31
Abstract: PURPOSE:To attain charge detection with high S/N without narrowing a band of a signal system by operating plural A/D converters in different timings synchronously with a read transfer clock of an image pickup element. CONSTITUTION:Control pulses Pc, Pc', Pc'', Pc''' whose phase is deviated by delay lines 13a-13c are applied to A/D converters 16a-16d. Thus, an instantaneous value of an output signal of an amplifier 12 at each timing is subjected to A/D conversion and digital video signals 17a-17d are added to an adder 14. Noise components applied by the amplification of the amplifier 12 are mainly a random noise component and the noise is suppressed by the averaging operation of the adder 14. An averaged video signal 15 being an output of the adder 14 becomes an output of a charge detection circuit. A noise suppressing effect in this case is expressed as 1/N<1/2>, where N is the number of A/D converters.

Filed: 1985-04-16
Abstract: PURPOSE:To obtain the W wire having uniform workability by estimating surely the workability of W wire by the value of the actual breaking distorsion obtd. with the ordinary temp. simple tensile test of the W wire having >=0.2mm diameter.
