Title: Driver circuit for laser diode
Inventor: ONISHI MASARU
IPC: H01S5/068
Filed: 1987-01-30
Abstract: PURPOSE:To control LD drive currents under the state of littler temperature change by monitoring a pulse current value, changing the pulse current value into a signal corresponding to a peak current value and controlling the current value of an FET by a differential signal obtained by comparing the signal with a desired pulse control signal. CONSTITUTION:An FET driver circuit has an FETQ, a bipolar transistor Tr and a capacitor C. A current monitoring circuit 2 has a low resistor R1 inserted into a circuit, through which LD drive currents flow, and an amplifier OP1. The amplifier OP1 outputs the mean value of LD drive pulse currents. Tr, R1, OP1, a mean value/mark rate circuit 4 and an amplifier OP2 constitute a negative-feedback control circuit bringing P to Vc. That is, when currents flowing through R1 are increased, the output P from a dividing circuit 4 is augmented, output voltage from the amplifier OP2 drops, the transistor Tr elevates conductivity and lowers emitter potential, and currents are reduced. When currents are diminished, the process is reversed.

Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To calculate numeric values arranged in a matrix form for respective columns and to always settle the calculated results in a range adjusted to the respective columns so as to fill them in spite of a filled character size and the number of numeric digits. SOLUTION: When an operation type in a vertical direction is designated for table data and the calculation range of m-columns/n-rows is designated, the number of operated operations in the calculation range is obtained and the calculation results for the respective columns are calculated. Then, the lateral sizes W(X) of respective calculated result numeric character strings are calculated based on a calculated result filling condition which is previously set. They are compared [K(X)>=W(X)] with the filling possible range K(X)[X=1-m] of result filling positions which are decided below the respective columns. When the lateral size W(X) of the result character string is not settled in the corresponding filling possible range K(X), a lateral size reduction rate S(X)[=K(X)/W(X)] corresponding to the rate is calculated.  The lateral size of the result character string of the size W(X) settled in the range K(X) is left as it is. The lateral size of the character string which is not settled is reduced in accordance with the reduction rate S(X). Then, they are filled and displayed within the filling possible range of the corresponding calculation results.
