Title: Semiconductor light emitting element
Inventor: KAWACHI MASARU
IPC: H01L21/365
Filed: 1987-03-02
Abstract: PURPOSE:To restrain the absorption into the inside of a crystal, and obtain an excellent LED for blue light, by forming, on a ZnSe substrate crystal, a ZnSSeTe layer whose forbidden bandwidth is narrower than that of the ZnSe crystal, and forming a generation junction. CONSTITUTION:The title semiconductor light emitting element comprises the following stacked in order on the ZnSe single crystal substrate 11; a first conductivity type ZnSxSe1-x-yTey(0<x<1,0<y<1) crystal layer 12 and a second conductivity type ZnSex'Se1-x'-y'Tey(0<x'<1, 0<y'<1) crystal layer 13. The forbidden bandwidth of the first conductivity type ZnSSeTe crystal layer 12 is made narrower than that of the ZnSe single crystal substrate 11. Therefore light absorption into the substrate inside can be reduced. Further, as for the mixed crystal composition of P-N junction, the forbidden bandwidth of P-type is made larger than that of N-type by changing the values of x, y and x', y'. Therefore, the internal absorption of a surface layer can be restrained to the utmost. Thereby, a blue-light emitting element having excellent characteristics and high luminous efficiency can be obtained.

Title: Rotary arc breaker
Inventor: PIEERU RUKUREERU
IPC: H01H33/70
Filed: 1990-02-26
Abstract: PURPOSE: To promote heat exchange between arc and a gas and improve the dielectric withstand strength and arc recovery voltage by dividing an arc extinguish chamber, installing the guide fins, and generating a speed difference between the arc and the gas in the heat exchange division. CONSTITUTION: Inside an arc extinguish chamber, a plurality of guide fins 56 stretching in the radial direction are installed on the cylindrical surface 28. The arc extinguish chamber 26 is divided in two concentrical divisions - the first is a peripheral division 60 surrounding the fins 56 and the other is an intermediate division 62 located between the first division 60 and the breaking gap. When the arc contacts 22 and 23 separate, the arc 64 is rotated at a high speed on an electrode 36 by a high temp. gas ring formed in the breaking gap. The speed v of the flowout gas stream is lower than the speed v of the arc on the electrode 36, and therefore, a difference in the speed is generated in the second division between the arc 64 and the flowout gas stream 68.  This speed difference promotes the heat exchange between the arc and SF6 gas in the division 62 to serve quick elimination of the arc.
