Title: Information recording medium
Inventor: OISHI SATORU
IPC: G11B7/257
Filed: 1984-09-05
Abstract: PURPOSE:To attain extraction of a tracking and focusing control signal at recording and reading and also to eliminate the variance of a reflection characteristic by providing a film of a low reflection factor between a substrate and a film whose optical characteristics are changed by heat. CONSTITUTION:The semiconductor laser light is scanned relatively and at the same time irradiated from the side of a substrate 1 in a pattern accordant with the information signal. Then the laser light passes through the substrate 1 and films 2 and 3 and reaches a film 4. This film 4 has a high absorption factor and absorbs the light to convert it into the heat. This heat is transmitted to heat up the film 3. Thus the optical characteristics of the film 3 are varied and the reflection factor is increased when it is viewed from the side of the substrate 1. Then the information signal is recorded in the form of the variation of the reflection factor. When this information signal is read out, the laser light of a smaller output than that of a recording mode is irradiated in the same way as that of a recording mode. Then the variation of the reflected light is detected.

Title: Crystal clock for automatically correcting original oscillation frequency
Inventor: TANEDA KAZUO
IPC: G04R20/20
Filed: 1987-07-25
Abstract: PURPOSE:To automatically correct the frequency deviation of a crystal oscillator caused by the change with the lapse of time, etc., by learning effect by a means which corrects the original oscillation frequency of the crystal oscillator by a quantity matching with a time error. CONSTITUTION:A time signal which is broadcasted is received by a receiver 1 automati cally at specific time. A time signal detection part 2 opens the gate of a time signal tone circuit in response to a previously predicting tone, converts the sine wave of the time signal tone into a pulse signal, and sends it to a counter 4 through a digital filter 3. The counter 4 counts the constant number of pulses and confirms that the received signal is the time signal tone. This time is compared by a comparator 5 with the time of a crystal clock in operation to fine their difference. The time error from the last time signal detection to the current time signal detection is detected every time. Then the error rate of the crystal clock in operation is calculated and processed so as to match with characteristics of a D/A converter 8 and a voltage- controlled crystal oscillator 9 and the result is stored in a memory 7 for a correcting value. The frequency of the voltage-controlled crystal oscillator 9 is adjusted according to the value in the memory 7.
