Title: Superhigh speed semiconductor laser
Inventor: MATSUEDA HIDEAKI
IPC: H01S5/00
Filed: 1989-07-11
Abstract: PURPOSE:To release restrictions on operating speed resulting from time required for recombination of carriers and the like by taking a semiconductor laser equipped with active layers and multi quantum well layers which are laminated in the direction that is different from the laminating direction of the active layers into wave guides so that polarizing directions of an optical mode become different respectively. CONSTITUTION:When an electric field vector performs oscillations by a mode located in the face of each active layer in the active layers 3 of a semiconductor laser, this basic laser light holds an electric field or an electric field component which intersects at right angles to each quantum well in a multi quantum well 8. Consequently, light excites electrons in the multi quantum well 8 until these electrons reach a state where they correspond to an optical mode intersecting at right angles to the well. When an injected current increases and excitation in the multi quantum well proceeds, inverted distribution takes place between double levels 13 and 14 in bands corresponding to different polarizing directions. Then, inversion-distributed electrons contribute to laser oscillations of resonators by means of end faces 7-9 and 10-11 at a fixed ratio. When the injected current decreases and it becomes less than a threshold level, inverted distribution disappears rapidly. As a result, output of the semiconductor laser is modulated at superhigh speed by a relaxation action in the bands of excitation conductor electrons.

Filed: 1994-07-29
Abstract: PURPOSE:To enable the calibration of a measuring element for measuring temperature within a specimen simply by attaching a calibration means of a temperature detecting element having a temperature control function to a thermal therapeutic apparatus. CONSTITUTION:A well 7 for the calibration of thermocouples making up a thermocouple calibration means is attached to an ultrasonic thermal therapeutic apparatus. The well for the calibration of thermocouples (well) 7 generates a reference temperature at the calibration. In other words, a temperature detecting point 22 of a thermocouple 21 is inserted into a thermocouple insertion hole of the well 7 in the calibration. A temperature control section 10 controls the well 7 under the control of a main control part 9 to a specified set temperature.

Thus, the main control section 9 alters the set temperature to accomplish a calibration of the thermocouple 21 automatically from the digital value (measured value) of the voltmeter 25 at that moment and the set value.

Abstract: PURPOSE:To make shading correction sure by defining the rate of the minimum value of digital data to the value of the picture element point of data digitally converting analog signals from a white reference board as corrected data. CONSTITUTION:The maximum value of image data from a RAM 26 for image data is calculated, and an upper limit reference potential VRT of a converter 25 is matched to the maximum value.
