Title: Semiconductor laser
Inventor: MURATA MICHIO
IPC: H01S5/00
Filed: 1997-03-10
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor laser having structure for realizing high oscillation efficiency. SOLUTION: A p-type lower clad layer 4 and an n-type upper clad layer 8 are formed on a p-type substrate 2 while sandwiching an active layer 6 and a stripe part 12 is formed on the upper clad layer 8 while being buried in a p-type current block layer 10. When a relationship nc <na <nb is set among the refractive indexes na , nb and nc of the p-type lower clad layer 4, the n-type upper clad layer 8 including the stripe part 12 and the p-type current block layer 10, light generated in the active layer 6 is guided while keeping symmetry below the current constriction part of the stripe part 12 having a higher refractive index than the lower clad layer 4. Consequently, light confinement rate is enhanced while lowering the threshold resulting in the enhancement of laser oscillation efficiency.

Title: Growth of semiconductor crystal
Inventor: KAWACHI TETSUYA
IPC: H01L21/368
Filed: 1986-03-13
Abstract: PURPOSE:To prevent the occurrence of dislocation due to dirt, by protecting a surface by means of a tellurium oxide layer during a period just before epitaxial growth after the surface is etched for purification. CONSTITUTION:A tellurium oixde film (TeO3)2 is evaporated by sputtering on a purified cadmium-tellurium substrate (CdTe)1 to form a protection film. Next, when the substrate 1 whereon the protection film is formed is inserted into a quartz ampule 21 which is filled up with a hydrogen reduction atmosphere (H2) with a mercury-cadmium-tellurium soultion 3 put therein and is at a temperature of 450 deg.C, the tellurium oxide film 2 formed on the substrate 1 is subjected to pyrolysis to be broken down into tellurium (Te) and water (H2O) and removed, so that the surface of the purified substrate 1 can be exposed. Then, the cadmium-tellurium substrate 1 is dipped in the mercury-cadmium-tellurium solution 3 by rotating the quartz ampule 21 by half, and liquid phase epitaxial growth is implemented to form a mercury-cadmium-tellurium layer (HgCdTe)4. A dirt sticking on the surface of the substrate is removed therefrom by the pyrolysis of the tellurium oxide layer, and thus the occurrence of dislocation due to the dirt can be prevented.

Title: Character processor
Inventor: TOSHIMA EIICHIRO
IPC: G06F17/22
Filed: 1987-03-11
Abstract: PURPOSE:To obtain a character process having high operability by reforming a reading dictionary not in a conversion state but in a loading state of an initial program. CONSTITUTION:A read train dividing means divides a read train inputted from a read train input means for each conversion unit with reference to a 2nd dic tionary. These divided read trains are converted into a KANJI (Chinese character)-KANA (Japanese syllabary) sentence by a read train conversion means with reference to a 1st dictionary. Then a dictionary reforming means is started by an initial program loading means and reforms a 2nd dictionary by extracting only the reading information out of the 1st dictionary. In such a way, a reading dictionary is automatically reformed from an original diction ary in an IPL state and therefore no waiting state is produced in a conversion state. Thus, it is possible to obtain a character processor having high operability.

Title: Sword edge-shaped shovel
Inventor: ARAZEKI HIROSHI
IPC: E02F3/02
Filed: 1998-02-19
Abstract: PROBLEM TO BE SOLVED: To prevent deviation of a shovel by providing at least two sword edge-shaped tips symmetrically arranged at the right and left sides against the center axis of a sword edge-shaped shovel, at the front end of the head. SOLUTION: A steel shovel head 21 is arranged at the tip of the handle 13 provided with a grip 12 in a sword edge-shaped shovel 11. The shovel head 21 is curved toward the central axial side of the shovel to reduce the width as both right and left side edges go to the tip and form two sword edges 22, 23 at the tip. The size and the protruded length of the two sword edges are made equal to each other and the two sword edges are symmetrically arranged at the right and left sides around the central axis 15 of the shovel 11 lest an unbalanced force rotating the head 21 or laterally shifting it acts on the head.  Then, when the sword edges have butted an underground obstacle, even though the head 21 is forced to deviate sideways owing to a force received from one sword edge 22, the other sword edge 23 butts the obstacle and supports the head 21, and hence, the head 21 is never shifted sideways as long as the obstacle is positioned between both sword edges 22, 23.

Title: Changeover device for advance and backing of service car
Inventor: FUKUI SATORU
IPC: F16H63/12
Filed: 1982-04-05
Abstract: PURPOSE:To release a hydraulic clutch in front of forward and reverse changeover structure at a neutral position, and to change over advance and backing without a shock by setting up an operating valve closing an oil-feed path at the neutral position to the oil-feed path for the hydraulic clutch. CONSTITUTION:The clutches 13, 14 are operated by oil pressure from the oil- feed path 108, and mounted in front of the forward and reverse changeover structure. A variable speed gear is changed over by changeover valves 90-93 combining actuators, and the forward and reverse changeover structure is similarly operated by a changeover valve 94 combining an actuator. The operating valve 98 supplies the actuator with oil pressure while also supplying the clutches 13, 14 with oil pressure through the oil-feed path 108. The clutches 13, 14 are also released because oil pressure is not supplied at a neutral position of the operating valve 98, and a shock is not generated when forward and reverse revlution are changed over because the revolution of a shaft system drops.
