Filed: 1980-06-30
Abstract: PURPOSE:To ensure an automatic calculation for both the service charge and tax, by providing a deduction key to temporarily deduct the service tax of respective sold goods from the total price of sold goods. CONSTITUTION:With push of a deduction key 5a, the signal is sampled by the fact that a clock pulse is applied to a set terminal S of a strobe circuit 14. Thus the output of an AND circuit 13a in a latching circuit 13 is made active to activate the set terminal of a flip-flop circuit F1. For the function of the circuit 13, a CPU6 performs a designation of address to obtain the output of a decoder 10 when an input terminal 11b of an OR circuit becomes inactive by the output of the circuit F1. Then no output of an OR circuit 11 is obtained even if an input terminal 11a of the OR circuit becomes active. Accordingly no signal emerges on a data bus line 8.

IPC: H01S5/042
Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To positively detect deterioration of a laser diode with use of a simple circuit. SOLUTION: A controller 1 outputs a light output control command LOC to an automatic power control circuit 2 to cause a light output of a laser diode LD of a laser diode module 3 to be controlled at a value corresponding to the command LOC. A monitor voltage output section 4 outputs a monitor voltage proportional to a drive current of the laser diode LD, and a comparator CP compares the monitor voltage with a reference voltage VO. A comparison result is issued to the controller 1. In its initial state, the controller 1 outputs a maximum command value LOCmax to cause a potential difference between plus and minus input terminals of the comparator CP to be adjusted at O volts using a tester 6. At the time of desired detection of deterioration of the laser diode, an inspection program is activated to execute deterioration detection.  The command LOC is gradually increased according to a programmed transition pattern to evaluate the deterioration on the basis of a ratio of the command value LOC and maximum command value LOCmax, when the monitor voltage exceeds the reference voltage.
