Title: Phase-shifting distributed feedback laser diode
Inventor: NAKANO KOJI
IPC: H01S5/00
Filed: 1990-08-30
Abstract: PURPOSE:To realize a stable monoaxial mode oscillation and to increase an optical output taken out to the outside by forming a structure in which a diffraction efficiency becomes small as a position comes closer to a phase-shifting region from a light- radiating face. CONSTITUTION:A diffraction grating having a protruding and recessed shape at a pitch that Braggs reflection condition coincides with an oscillation wavelength is formed on a semiconductor substrate 3. The diffraction grating has a structure in which its cycle is shifted by lambda/4 near the center of an element in the same manner as conventional lambda/4-shifting DFB-LD's. However, when the diffraction grating is formed, it has a structure in which a height H from the bottom of a valley up to the top of the diffraction grating 1 becomes lower as a part becomes closer to a phase-shifting region 2 from a light-radiating face R. Thereby, a diffraction efficiency becomes small as the part comes closer to the phase-shifting region 2 from the light-radiating face. In this example, the height of the diffraction grating near the light-radiating face is set at 500Angstrom , the height of the diffraction grating in the phase-shifting region is set at at 200Angstrom  so that the height of the diffraction grating becomes gradually low from 500 to 200Angstrom as the part comes closer to the phase-shifting region from the light-radiating face.

Title: Home controller
Inventor: MAYAHARA NAGAYOSHI
IPC: G06F11/00
Filed: 1994-09-27
Abstract: PURPOSE: To exclude the erroneous readout of data and to operate a home controller normally by judging whether or not the data is being written on a ROW and performing such control so as not to perform readout and write simultaneously. CONSTITUTION: A control part 4, when two application programs(AP) being operated alternately periodically, sets a judging flag when the AP on one side writes the data on a memory area 8. When the AP on the other side reads out the data from the area 8, the Judging flag is checked, and when it is already set, a standby state is set until the judging flag is reset. When the AP on one side completes the write and the judging flag is reset, the AP on the other side can perform the readout at this time. Therefore, it is possible to exclude simultaneous read/write work by using the reset/set of the judging flag as a judging means while the write on flash memory is being performed, which excludes the erroneous readout of the data.
