Title: Semiconductor laser
Inventor: ASAI AKIHIKO
IPC: H01S5/00
Filed: 1987-02-23
Abstract: PURPOSE:To lower a threshold electric current by a method wherein a mesa stripe composed of an inverted-mesa-shaped part, a vertical-shaped part and a forward-mesa-shaped part in succession is formed on a multilayer-film structure wafer which is formed by piling up semiconductor layers including an active layer. CONSTITUTION:A p-type InP clad layer 12, an n-type In1-xGaxAs1-yPy active layer 13 and an n-type InP clad layer 14 are grown in succession on a p-type InP substrate 1; after that, a belt-shaped insulating film 23 is formed. Then, an inverted-mesa-shaped part 20 is formed by a first etching process; a vertical- shaped part 21 and a forward-mesa-shaped part 22 are formed by a second etching process; after that, a p-type InP buried layer 15, an n-type InP buried layer 16 and a p-type InP buried layer 17 are grown in succession. The insulating layer 23 is removed, and an n-type electrode 18 and a p-type electrode 19 are formed. By this setup, because the active layer 13 can be made narrow, it is possible to stabilize an oscillation mode of a laser beam and to lower a threshold electric current.

IPC: G06F9/44
Filed: 1992-02-27
Abstract: PURPOSE:To improve the problem solving speed in a system which solves the problems with application of the inference rules by changing automatically the applying order of the inference rules. CONSTITUTION:When a problem is inputted from a problem input part 11, an inference part 13 solves the problem with sequential application of the inference rules included in an inference rule control part 12.

Meanwhile, an inference rule monitoring part 15 monitors the problem solving process of the part 13 and measures the probability of success and the average processing time of each inference rule to transmits them to an inference rule statistic information control part 16. When the solution of the problem is complete, an inference rule order changing/deciding part 17 is started to change the applying order of the inference rules. Thus, it is possible to decide whether the average problem solving speed can be improved or not based on the information stored in the part 16.

Abstract: PURPOSE:To verify a multibit error at a high speed by producing respectively the array codes from the position codes of the bit trains, a bit matrix from the array codes, a column characteristic code from the binary number of each column of the bit matrix, the more and less significant column characteristic codes from the column characteristic codes, and a multibit error inspection code by connecting the more and less significant characteristic codes to each other. CONSTITUTION:A more significant column characteristic code 10 and a less significant column characteristic code 11 of a bit train 9 are produced and then connected together for production of a multibit error inspection code 12 of the train 9. Then a more significant column characteristic code 14 and a less significant column characteristic code 15 are produced for a bit train 13 where a 6-bit error is occurred in the processing of the train 9. Both codes 15 and 15 are connected together for production of a multibit error inspection code 16 of the train 13. Then an EOR is secured between both codes 12 and 16 of both trains 9 and 13 for production of a multibit inspection comparison code 17. Thus it is possible to verify the occurrence of a bit error since the digit of a code 1 is included in the code 17.

Title: Fuel control unit at starting time
Inventor: NAKASHIMA TETSUO
IPC: F02D41/06
Filed: 1981-03-23
Abstract: PURPOSE:To obtain high characteristic in the start of a engine preventing the wetting of plug at the starting time by arranging a selector prohibiting an increasing amount of fuel at the time of opening degree of throttle valve and temperatue of the engine being more than the specific value in a fuel injection type engine. CONSTITUTION:Matrix memory 1 memorizes fundamental fuel injection timing signal Ti with revolution number Ne, suction negative pressue PB and opening degree thetath of throttle valve as a parameter. Arithmetic unit 4 of rectifying fuel signal at the starting time calculates the corrected fuel injection timing signal Tic adding the correcting sum of the increased amount at the starting time to the injection timing signal Ti with temperature Te of the engine and starter signal St are inputted. When the opening degree thetath of value is bigger than the arranged value and temperature of engine Te is higher than the arranged value, increasing amount of fuel at the starting time is prohibited because a selector 7 selects the fundametal fuel injection timing signal Ti through AND gate 6. Thus wetting won't be produced on a plug.

Abstract: PROBLEM TO BE SOLVED: To facilitate erection work by moving a frame member to an erection position hauntingly with a crane and allowing a remote position measuring device to follow and collimate a reflector in automatic mode and thereby correcting the erection position of the frame member. SOLUTION: An automatic measuring instrument O is set up substantially in the central part of a non-frame structure and a reflective prism is mounted at a basic reference point A, thereby entering design erection positions of each frame member 10 into a computer. Then, the frame members 10 are suspended with a crane 13 and temporarily fixed at the design erection positions, using a scaffolding 11 and a truss structure 12. After the basic reference point A of the automatic measuring instrument O is collimated as an original point posture, a laser beam is irradiated at a reflective prism Px mounted on the frame member 10.  Then, the position of the reflective prism PX of the frame member 10 is measured, thereby determining the deviation between the measured position and the design erection position and correcting the erection position of the frame member 10 so that it may be fixed at the design erection position. It is, therefore, possible to execute erection work with ease and high accuracy as well.
