Title: Optical semiconductor device
Inventor: KAWARATANI MASAHIKO
IPC: H01L31/02
Filed: 1990-08-20
Abstract: PURPOSE:To prevent the occurrence of glass cracks and dissolve poor air- tightness by stepping the lead, which is led out to outside being surrounded by an insulator, and positioning the stepped part outward of the surface of the insulator. CONSTITUTION:For an optical semiconductor device 2, two stepped cylindrical leads 1 are fixed to a stem 8 by a glass material 2. Furthermore, to ensure high quality without causing glass cracks, the step A of the stepped cylindrical lead 1 is positioned not less than 1mm and less than 2mm below the bottom of the glass material 2.

Therefore, the leakage of charged gas can be suppressed.

To put it concretely, the number of the continuously coincident records is outputted when it reaches a prescribed upper limit value, and the record group prior to the group is outputted as the insertion group. The record which does not coincide with any record as the result of comparison is outputted as an elimination record. When the number of comparing times reaches prescribed value in such a case, it is set to be the elimination record.
