Title: Laser oscillator for q switch
Inventor: TOMIE TOSHIHISA
IPC: H01S3/11
Filed: 1983-02-18
Abstract: PURPOSE:To obtain a high quality and highly stable output of high synchronism by pulse-exciting energy, which is sufficiently larger than the oscillation threshold energy of a laser oscillator and executes false stationary oscillation. CONSTITUTION:A YAG rod 4 is excited by a flash lamp by a resonator constituted by reflecting mirrors 1, 8 and laser-oscillated. A lateral mode and a longitudinal mode are controlled by a pin hole 5 and an etalon 6. An acoustic optical element 7 for synchronizing the modes is arranged in order to obtain extremely short pulses. A Pockels-cell 2 and a polarizer 3 are used for a Q switch. Threshold energy is approximately seven joule, but pulse excitation in approximately sixteen joule is executed. A giant laser pulse row appears after approximately 200+1sec after the operation of the Q switch. The laser pulse row acquired is very excellent, and the stability of energy is also + or -1% or less. A jitter is every small.

Abstract: PURPOSE:To manufacture an embedded semiconductor laser by one time crystal growth by forming a current blocking layer on portions other than a current path including an active layer. CONSTITUTION:Strip-like first, second and third grooves 11, 12 and 13, respectively, are formed in a substrate 2 so as to be parallel to one another. A current blocking layer 3 is laminated except a portion between the first groove 11 and the third groove 13. A buffer layer 4 and an active layer 5 are sequentially laminated on the current blocking layer 3. further, a buffer layer 8 and an active layer 9 are sequentially laminated in the central second groove 12. A clad layer 6 is laminated over the whole surfaces of the active layers 5 and 9. The active layer 9 which becomes a light emitting region is formed in the central groove 12 among the three grooves. The two outside grooves 11 and 13 are formed to prevent the current blocking layer which is the first crystal growth layer from being laminated in the central groove 12. Further, the active layer 9 laminated in the central groove 12 is the light emitting region and, to operate in a stable single transverse mode, the width of the active layer 9, namely, the width of the central groove 12 is controlled within a range of some degree. Thus, a manufacture can be executed by one time crystal growth.

Title: Three-dimensional acceleration sensor
Inventor: KUSHIDA TAKEO
IPC: G01P15/18
Filed: 1988-02-09
Abstract: PURPOSE:To expand a detection range of acceleration, by producing an internal ball housed in an external ball from magnetic material such as iron. CONSTITUTION:When an object to be measured is accelerated, for example, in the X-axis, an internal ball 2 moves by an inertial force along the X-axis from the center reference position opposite to the direction of the acceleration. Then, the internal ball 12 continues of move until the sum of a repulsive force of one magnetic fluid 4 on the X-axis and an attraction force to return it to the center reference position by a magnetic field caused by four permanent magnets 5 arranged on the Y and Z-axes equals the inertial force. As a result, a difference is caused between mutual inductances of a pair of transformers 8 on the X axis to change an input of a differential transformer from zero. Hence, the output is rectified synchronously to obtain an acceleration signal Sx by being amplified after passing through a high frequency noise cutting filter. This represents the X-axis acceration by the size of an absolute value thereof and also the direction thereof by being given as positive or negative. Likewise, the acceleration and direction thereof for the Y and Z axes can be detected separately.
