Patent JP-H0621572-A (JP)
Title: Semiconductor laser
Inventor: SUGAO SHIGEO
IPC: H01S5/00
Filed: 1992-07-02
Abstract: PURPOSE:To obtain a semiconductor laser wherein heat generation due to contact resistance does not occur, by forming junction layers capable of reducing contact resistance, between a clad layer and an electrode. CONSTITUTION:In order to reduce contact resistance, a first junction layer 17 (nitrogen-doped Zn0.25Cd0.75S, thickness 0.1mum) and a second junction layer 18 (nitrogen doped Zn0.25Hg0.75S, thickness 0.1mum) are formed between a second clad layer 13 and a second conductivity type electrode 15. Thereby the forbidden bandwidth can be narrowed. Further contact resistance can be reduced by forming the junction layers of material wherein defect due to mismatching with lattice constants of a substrate 10 is not generated. Since the forbidden bandwidth of the second junction layer 18 is small to be nearly equal to that of gallium aarsenide of a substrate 10, low contact resistance can be expected by doping concentration of about 10<18>cm<-3>. In the above case, a composition matched in lattice with the substrate 10 can be obtained in the first junction layer 17 and the second junction layer 18, by about 25% zinc ratio of group II component composition. Thereby dislocation defect due to lattice distortion is not generated.

Filed: 1982-11-19
Abstract: PURPOSE:To fix a toner image without staining a reverse surface by supplying a polymer which is obtained from a multifunctional monomer to a member which contacts the outer circumferential surface of a fixing roll. CONSTITUTION:A cleaning roll 4 collects sticking toner on the fixing roll 1 at the outer circumferential surface and toner is deposited on its surface, but a reactive polymer leaches out of an internal liquid holding layer 6 to the outer circumferential surface of the roll 4, so toner collected or deposited on the outer circumferential surface increases in elasticity in fusion to turn on the heater 3 of the roll 1; even when toner material on the roll 4 is heated and fused, transposition to the roll 1 is suppressed and no toner moves to a roll 2, so that the back is prevented from being stained. The reactive polymer uses preferably polyester resin and polyamide resin and multifunctional monomer components having, specially, >= three functions are incorporated in a monomer regarding condensation by 15-40mol% on the basis of the whole.
