IPC: H01S5/068
Filed: 1980-09-19
Abstract: PURPOSE:To stabilize the output of a semiconductor laser by preparing a plurality of reference operating temperatures of the laser corresponding to the detected state of the actual operation temperature, and selecting the optimum reference operation temperature at that time. CONSTITUTION:The operating temperature of a semiconductor laser 1 is detected by a temperature sensitive element 3 as a voltage value V, and the detected value V is compared with the voltage range predetermined in respective window comparators 41, 42. The voltage ranges of more than the detecting voltage value V0 at the reference operation temperature t0 and lower than the V0 are respectively set in the comparators 41, 42. When the detected value V is higher than the V0 in this manner, a gate circuit 51 is opened by the comparator 41 to select the reference voltage E1, to then apply it to a comparator 6, and when it is lower than the V0, the gate circuit 52 is opened by the comparator 42, the reference voltage E2 is selected, and is applied to the comparator 6. Thereafter, a Peltier element 8 is operated by the compared output of the comparator 6, and the laser 1 is retained at the temperature t1 or t2 corresponding to the voltage E1 or E2.

Filed: 1992-05-25
Abstract: PURPOSE:To switch from a first semiconductor laser diode to a second semiconductor laser diode uninterrupting if the first semiconductor laser diode is out of order. CONSTITUTION:When the intensity of the output light of a first laser 11 is lowered to a level below a predetermined value, the input B of an OR circuit 15 is turned to a low level by a switching signal and, at the same time, the control input of a second semiconductor laser driving circuit 22 is turned to a high level to start the operation of a second laser 21.

Title: Optical character reader
Inventor: AOKI NAOTO
IPC: G06K9/00
Filed: 1989-05-29
Abstract: PURPOSE:To smoothly execute the reading work of a slip even when a reader is stopped by detecting the number of slip data, which are written to a buffer memory but not transferred, and displaying the bounday identification information of the slips calculated according to this detected number. CONSTITUTION:The number of the slip data, which are written to a buffer memory 11 but not transferred, is detected by a slip data number detecting part and this number of the slips are also exhausted from a read part 12 while being overlapped with the slip whose data are already processed. When the optical character reader is stopped, the buffer memory 11 is initialized. Accordingly, these slip data are erased. However, the slip data are written to the buffer memory 11 according to the slip boundary identification information displayed in a display part 20. Even when the slip data are written to the buffer memory 11, an operator can know boundary between the already transferred slip and the slip not to be transferred yet. Thus, even when the reader is stopped, the reading work of the slip can be smoothly executed.
