Patent JP-H11261100-A (JP)
Title: Manufacture of photo-semiconductor device
Inventor: SUZUKI DAISUKE
IPC: H01S5/00
Filed: 1998-03-09
Abstract: PROBLEM TO BE SOLVED: To enhance quality by decreasing a dark current, by a method wherein, after a mesa structure is formed, it is held for a predetermined period of time in the gas atmosphere containing chlorine. SOLUTION: A mesa structure containing an InGaAs layer is formed by wetetching. After a mesa structure is formed, before embedding growth of a Fe-InP layer 19, a side face of an exposed InGaAs optical absorption layer 14 has been beforehand held for a predetermined period of time, for example, in the HC1 gas atmosphere to etch. Thus, a regrowing interface H in which the deterioration of crystallinity occurs and impurities are piled up is so-called pre-etched. In other words, just before the crystal growth of the Fe-InP layer 19, the regrowing interface H of the Fe-InP layer 19 is purified to set the InGaAs optical absorption layer 14 in a fine state. Thus, for example, it is possible to reduce a dark current in a finished product of a wave guide type photodiode PD and to enhance the quality.

Filed: 1996-03-13
Abstract: PROBLEM TO BE SOLVED: To make it possible to illuminate uniformly light, which is provided with full output and a low coherence, on a surface to be illuminated as the light source for an exposure device stably for a long time by a method wherein optical elements, which make light from the laser elements of a laser beam source diverge, are respectively provided on the light emitting end of each laser element. SOLUTION: A laser beam source is constituted of 10×10 = total 100 of laser elements. Each laser element has a semiconductor laser 11 which generates pumping light, an optical film 12 which transmits the pumping light, a solid laser 13 and an optical element 14. By the way, the laser 11, which generates the pumping light, emits light, which excites the laser 13, and the light emitted from the laser 11 is made to enter the fiber 12 and is guided to the laser 13. Thereby, a temporal and-spatial coherence can be reduced. Moreover, light emitted from a plurality of the laser elements can be illuminated on a surface to be illuminated uniformly and superposedly.

Abstract: PROBLEM TO BE SOLVED: To enable a user to easily confirm the propriety of needle position setting conditions by detecting the position of a mounted needle and displaying a needle position pattern corresponding to detected needle position data and stitch constitution sewn by a set needle position. SOLUTION: Signals are sent from a CPU 60 to a needle position detection means 7 and a needle position detection operation is performed. When the detection operation is ended, the detected needle position data are inputted to the CPU 60 and a detection piece is restored. Then, the CPU 60 obtains the address of setting pattern display information matched with the detected needle position data, reads the information of the needle position pattern and the stitch constitution corresponding to the detected data from a display information storage means 61b and displays it at a display panel 8. The user resets the needle when display is not the desired stitch constitution. Thus, the needle position is easily confirmed and whether or not it is suited to the desired stitch constitution is recognized.

Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To provide an ultrasonic endoscope which can provide good ultrasonic images by preventing noises that may be produced by the irregular reflections of ultrasonic waves radiated toward an end part main body. SOLUTION: This ultrasonic endoscope causes ultrasonic wave radiated from an ultrasonic piezoelectric transducer 16 to reach an end part main body 4 when the acoustic axis 16a of the ultrasonic piezoelectric transducer 16 reaches near the boundary face between an end cap 10 and the end part main body 4. Then most of the ultrasonic waves radiated from the ultrasonic piezoelectric transducer 16 undergo total reflections, so that a reflected echo significantly greater than a reflected echo signal reflected by the end cap 10 returns. From this, the acoustic axis of the ultrasonic piezoelectric transducer 16 is determined to pass over the end part main body 4, during which the radiation of the ultrasonic waves from the ultrasonic piezoelectric transducer 16 is stopped temporarily.
