Title: Pickup cartridge
Inventor: MATSUMURA ASAYUKI
IPC: H04R11/08
Filed: 1986-01-28
Abstract: PURPOSE:To make noiseless reproducing possible by coating surfaces of a stylus tip and a cantilever with a conductive material and using a conductive adhesive. CONSTITUTION:Surfaces of a stylus tip 2 and a cantilever 1 are coated with a conductive material and a conductive adhesive 15 is used to connect electrically individual parts. Since the electric charge charged on a record is migrated from the stylus tip 2 to the earth through the cantilever 1, a wire 6, a supporting pipe 7, and a sleeve 8, the electric charge charged on the record disk is not discharged at a high voltage and has not an influence upon a signal output path. Though the surface of the stylus tip 2 is coated with the conductive material, the electric charge on the record disk is migrated to the cantilever 1 with a slight potential because the distance from the surface of the record to that of the cantilever 1 is very short, and the influence upon the signal output path is reduced.

Title: Buried type semiconductor light emitting element and manufacture thereof
Inventor: KAWAKAMI GOJI
IPC: H01S5/00
Filed: 1990-01-27
Abstract: PURPOSE:To enable a semiconductor light emitting element to be buried shallow and micronized, lessened in leakage current, and to trap light well by a method wherein a GaAs thin layer of the same conductivity type with a clad layer or an AlGaAs thin layer specified in Al concentration is provided adjacent to an active layer in an Al containing clad layer. CONSTITUTION:An N-GaAs or an N-GaAs thin layer 21 whose Ali concentration is 10% or below is inserted adjacent to an active layer inside an N-Al0.6GaAs clad layer 2. At this point, light emitted from an InGaAs distorted layer is 1mum or so in wavelength and provided from being absorbed by the inserted GaAs thin layer 21. As the refractive index of GaAs is larger than that of AlGaAs, the equivalent refractive index Neq of an active layer becomes slightly larger in propagation mode by providing the thin layer 21. When the GaAs thin layer the same as above is provided inside an upper P-Al0.5GaAs clad layer 4, a refractive index difference can be made large in a lateral direction when a ridge type semiconductor laser is formed, so that light can be effectively trapped in a lateral direction.
