Title: Semiconductor optical amplifier device and its usage
Inventor: NITTA ATSUSHI
IPC: H04B10/07
Filed: 1991-11-11
Abstract: PURPOSE:To obtain a semiconductor optical amplifier device which has a stable amplifying operation regardless of the change of an injected current. CONSTITUTION:In a first active layer 3, carrier are accumulated by current injection and a refractive index is reduced by a plasma effect. In two active regions of which a second active layer 4 is composed, a refractive index is increased depending upon the magnitude of the superposed integral of the active region and the light distribution. Therefore, the change of the refractive index which is sensed by a light with a current injection is positive or negative in the first active layer 3 and the second active layer 4. With this constitution, the optical length of a resonator can be constant regardless of an injected current value. This fact has an effect that a peak avelength created by a resonance phenomenon caused by end reflection is not changed.

Title: Layout processing method in raster plotter
Inventor: MIYASAKA YUTAKA
IPC: G06F3/13
Filed: 1988-12-21
Abstract: PURPOSE:To keep a time required for a layout process constant regardless of the increase of the quantity of drawing data by dividing a bit map memory into two parts and transferring the drawing data stored in one of both memory parts to an idle area of the layout storing area of the other memory part. CONSTITUTION:A bit map memory BMM is divided into a work area S2 and a layout storing area S1. Then the input drawing data DT is written into the area S2 after the vector/raster conversion. A CPU checks the idel, area state of the area S2 and decides whether the area S1 includes an idle area equivalent to the size of the data DT or not. If not, the data on the area S1 is outputted to a raster plotter engine E and the memory of the area S1 is cleared to zero. The the drawing data is transferred to the S1 from the S2. Thus the increase of the layout processing time can be evaded despite the increase of the quantity of drawing data.
