Abstract: PURPOSE: To easily and inexpensively reproduce a clock frequency by providing a resonance circuit, consisting of windings of a transformer and a capacitor and selectively connecting the resonance circuit to a frequency converter or a clock frequency divider. CONSTITUTION: When a data signal UE1 of 64kbits/s, processed as an input signal by on G703(CCITT) is applied, a capacitor C2 is short-circuited by closing of a switch S1. Then, a resonance circuit SK tunes to spectrum line of 28kHz of the signal UE1, and an output side E1 of a multiplexer MUX is connected to an input side E2. Consequently, a resonance circuit signal U1 is supplied to the input side of the multiplexer through a gate G and a frequency converter PLL. Specifically, coefficients of clock frequency dividers T3 and T2 are 8 and 1/7 respectively, and the frequency 32kHz of a required output signal UA is obtained by a multiplication between the both coefficients and the 28kHz signal U1, with respect to the frequency of the output signal.

Filed: 1988-09-22
Abstract: PURPOSE:To eliminate the adverse effect on alignment detection due to the winking of an eye under examination, and improve the measuring or recording accuracy of the eye under examination by prohibiting the action of alignment detection for a given time by detecting the sudden descending of the output signal from an alignment detection means. CONSTITUTION:When the alignment of a device is made by an operator, e.g., loci S-S' are traced, points M1 and M2 are counted with a pulse counter 16b at a level 2, and when winding occurs between points S1 and S2, since alignment deviation becomes larger, an output signal is suddenly descended from the point S1, the tilt of the descending variation is detected with a wink detection circuit 12, the counting actions of pulse counters 16a, 16b, and 16c are held, a timer 19 is actuated concurrently, and a measuring action prohibition period occurs. After a given time by the action of the timer 19 passed, the pulse counters 16a, 16b, and 16c are released from a holding condition by the output signal from the timer 19, and counting is resumed. This eliminates unrequired counting due to winking.

Title: Optical transmitter
Inventor: MORI TAKASHI
IPC: H04B10/572
Filed: 1988-09-28
Abstract: PURPOSE:To leng then service life of an LD and to reduce power consumption of an LD drive circuit provided with an electronic cooling circuit by a method wherein the electronic cooling circuit is controlled depending on the strength of a signal input. CONSTITUTION:When an input signal is small in amplitude (low level in level diagram), current flowing through a transistor 5 is small, so that voltage VAB between both ends of a resistor R is small and the output voltage VO of an operation amplifier 4 is made to decrease. Therefore, current flowing through a transistor 6 is small, so that current flowing through a Peltier element 3 is small. Next, when an input signal is large in amplitude, a current flowing a transistor 5 becomes large, so that the voltage VAB between both the sides of R becomes large. Therefore, the output voltage VO of the operation amplifier 4 increases, so that a current flowing through a transistor 6 becomes large. By this setup, current made to flow through a Peltier element can be controlled by the size of amplitude of an input signal. Hence the service life of the LD can be effectively made prolonged and the power consumption can be reduced.
