Title: Method for obtaining recording pulse condition of optical disk and its device
Inventor: FURUMIYA SHIGERU
IPC: G11B7/0045
Filed: 1999-11-04
Abstract: PROBLEM TO BE SOLVED: To reduce an influence of a writable optical disk and variance of a recording and reproducing characteristic by executing a first trial writing on the optical disk, detecting a first jitter from a reproducing signal, adding a first prescribed quantity of variations to positional information to a combination between a mark length and a space length and executing a second trial writing by the use of uniformly varied positional information. SOLUTION: A recording pulse standard condition preiminarily recorded on an optical disk 1 is read and data are trial written. Next, random data are reproduced by using a multi-pulse data 19 and a jitter of a reproducing signal is measured. A recording pulse standard condition 10 sent from a recording pulse standard condition demodulating means 9 is uniformly varied with a uniform varying device 25a included in a variation means 25 and is trial written on the optical disk. A jitter voltage obtained by being repeated while varying a correction value 23 is collected, and a combination in which the large jitter voltage in the head end and the tail end among the jitter voltages becomes the minimum value or an allowable value or less is used as the optimal recording condition.

Filed: 1990-11-21
Abstract: PURPOSE:To reduce the circuit scale of an A/D converter and to reduce a chip area and the power consumption by incorporating a sample-hold function and a residual signal amplifying means in a voltage comparator. CONSTITUTION:By a first timing PHI1, an input signal is sampled to the capacity of each voltage comparator in an A/D conversion block 102. Subsequently, by a second timing PHI2, a sampled voltage Vin and the upper reference voltage Vref U of each comparator are compared, and the A/D conversion of the high- order bit is executed. By a third timing PHI3, the high-order (m) bit obtained by a second timing is converted to an analog signal Vdac by a D/A converter 103 and applied to the comparator. The comparator amplifies a residual signal by using two pieces of capacities 306, 307, and samples the residual signal amplified by a second capacity 306. By a final fourth timing, the residual signal sampled by a second capacity 306 and a reference voltage Vref L are compared, and the A/D conversion of the low-order bit is executed.

Title: Protective relay
Inventor: MAEDA KOJI
IPC: H02H3/02
Filed: 1990-11-20
Abstract: PURPOSE:To obtain a protective relay operable on a 50Hz/60Hz common arithmetic processing circuit, by calculating the products of the cubes of sampling data of current and voltage, and so on, by controlling the sampling data so as to remove the components of the second harmonics and sampling time width, and by producing an output at a judging quantity calculating section. CONSTITUTION:Voltage and current data are stored in storing means 3, 4, 6-8. And an operation expression for system protection to be calculated by using those values is obtained. The operation expression is composed of the first and second electric quantities. A power directional component is found from a value obtained by dividing the first electric quantity consisting of a sampling conditional expression having the product of the cubed amplitude values of the current and voltage as a multiplicand, by the second electric quantity consisting of a sampling time conditional expression having a squared amplitude value of the voltage as a multiplicand. And 4-rule calculating means 9-33 calculate under conditions that the conditional expressions of the first and second electric quantities are not zero, and that the power directional component is higher than zero, and a judging quantity calculating section 100 produces an output of a judged result. And this releases the sampling time width from dependency on the system frequency.

Filed: 1997-10-31
Abstract: PROBLEM TO BE SOLVED: To provide an oscillator structure of sound source device which can read the next musical sound waveform simultaneously, during the time to continue to read out a musical sound waveform from a memory means. SOLUTION: Wave read unit WRU 301 reads a waveform data from a waveform data ROM 399, depending on a wave clock WCK. The waveform data read from the TOM 399 is output to the outer side from a selector SEL 302 as a waveform signal SG0, and when it is informed that the waveform signal reaches to the head of the repeating part in the waveform data, the wave read unit 301 delivers the waveform data to a RAM 303 to memorize there, and when it is informed that is comes to the finish of that part, the wave read unit stops the transfer of the waveform data. And when there is a repeating part in the waveform data read from the ROM 399, after that, the selector 302 converts to the reading from the ROM 303, instead of the reading from the ROM 399, and it starts the next waveform reading process while outputting the waveform signal SG0.
