Abstract: PURPOSE:To reduce an oscillation threshold current and to enable self-excited oscillation in a wide output range by forming an active layer of multi quantum well structure and by setting an equivalent refraction factor difference between a region near a current injection path and a region of the outside thereof to a specified value. CONSTITUTION:A first clad layer 3, a first optical guide layer 4, an active layer 5 of multi quantum well structure, a second optical guide layer 4', and a second clad layer 6 are laminated on a semiconductor substrate 1. A thickness of the clad layer 6 at an outside of a ridge section 31 is made 0.2 to 0.6mum and an equivalent refraction factor difference between an outside and an inside of a region near the ridge section 31 is made 3X10<-4> to 5X10<-3>. A light confinement section is formed in a region near an emission edge face by breaking the active layer 5 of multi quantum well structure. According to this constitution, an oscillation threshold current can be reduced and self-excited oscillation can be realized in a wide output range since the active layer 5 is provided with a quantum well structure. Moreover, astigmatic difference can be reduced by forming a light confinement section to the region near the emission edge face and thereby strengthening a refraction factor waveguide mechanism.

Abstract: PURPOSE:To display the accurate position of a vehicle by assuming artificially satellite when the arrival of a radio wave from one of three artificial satellites is stopped. CONSTITUTION:When there are three receivable satellites, a reception position computing element 22 calculates both data, i.e. tracks from signal lines 20a and 20b and pseudo distance and the reception position of the vehicle 10 is displayed 24. If one of the satellite is made unreceivable because of the presence of a shield, the position of the vehicle 10 at the position is regarded as a pseudo satellite and azimuth and distance data from a magnetic goniometer 14 and a distance meter 16 are inputted to a pseudo computing element 26. On the other hand, measured position data on the vehicle 10 at the time t1 is sent to the computing element 26 as position information on a pseudo satellite and the pseudo distance data on the pseudo satellite obtained by processing said azimuth and distance data is sent to the computing element 22. The computing element 22 computes the measured position of the vehicle 10 on the basis of received data from receivable satellites at the current time t2 from a receiver 18, i.e. pseudo distance and satellite position data, the pseudo distance of the pseudo satellite of the computing element 26, and the position of the pseudo satellite of the device 2, so that the measured position is displayed 24.

Abstract: PURPOSE:To prevent the roughening of a casting surface so as not to generate the carbide of molten metal of ZrC, etc., on the inner surfaces of a graphite- made crucible and mold. CONSTITUTION:A graphite mold 2 is fitted to the bottom part of a graphite crucible 1 and the inner surface of the crucible 1 is contacted with ceramic liners 1a, 1b of the oxide, such as Y2O3F, CaO, MgO, more stable than zirconium oxide and in the crucible side of the mold 2, a pipe 3 of the same kind of the ceramic, etc., is inserted. The elution of the carbon from the graphite is prevented with the ceramic layer, and the ceramic layer is not eroded with the zirconia. Therefore, ZrC is not generated in the crucible and the mold. While cooling with a water cooling copper jacket 5, a solidified rod of Zr-copper alloy (a) is drawn with drawing pinch rolls 6 by using a pure copper rod 4 as a guide. Then, the solidification of the Zr copper alloy (a) is made to be in the pipe 3 to prevent the generation of ZrC. By this method, the roughening of the casting surface of the drawn Zr copper alloy rod is not developed.

Title: Electron beam pattern drawing method
Inventor: ASAUMI MASASHI
IPC: H01L21/027
Filed: 1990-01-17
Abstract: PURPOSE:To realize image writing precision equivalent to a continuously moving system equipment by using a pattern drawing equipment of step-and-repeat system, by a method wherein electron beam scanning of a constant region, which is performed while a stage is stopped, is continuously performed several times. CONSTITUTION:When a stage is in an almost stopped state, drawing of the same pattern is performed, e.g. four times, before stage transfer 6 for the next field pattern drawing is started. That is, patterns 3-5 are written in the order of 7-8 by 1/4 exposure amount of an ordinary writing method; the patterns 3-5 are written in the order of 9-10 by the same exposure amount; after writing is performed in the order of 7-8 and the order of 9-10, the stage transfer 6 is performed, and then the writing of the next field 2 is started. By performing, the nth writing process (n being an odd number) and the (n+1)th one in a manner that they are mutually reverse in the writing order, the change ratio of a deflecting signal is smaller, and higher precision can be obtained. Thereby the error of pattern position caused by the delay of response, the overshoot, etc., of a deflector system can be averaged by continuously writing each field several times, and highly precise pattern can be formed.
