Title: Optical semiconductor device, semiconductor relay device and optical signal receiver
Inventor: HAYAZAKI YOSHIKI
IPC: H01L31/12
Filed: 2003-08-26
Abstract: <P>PROBLEM TO BE SOLVED: To obtain an optical semiconductor device in which a conversion efficiency of an optical energy is high.  <P>SOLUTION: A p-type semiconductor layer 3 corresponding to the SOI layer of an SOI substrate 10 comprises a plurality of planar semiconductor islands 5 which are isolated from each other by a groove 4 and a groove 8 formed as trenches. An n-region 6 and a p-region 7 are formed on a pair of side planes facing a pair of the grooves 4 pinching each semiconductor island 5, whereby each semiconductor island 5 constitutes a photodiode cell. The groove 4 is filled with an electrode material 14, and the groove 8 is filled with an insulating material 18. A plurality of the photodiode cells are in series connected to each other. A depletion layer which contributes to a photoelectric transfer is formed over a wide region of the semiconductor island 5. In the range of a light arrival distance, as the groove 4 is deeper (i.e., the semiconductor layer 3 is thicker), the usable efficiency of the optical energy is enhanced.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Title: Image forming apparatus
Inventor: ASANO KAZUO
IPC: H04N1/405
Filed: 2003-09-03
Abstract: <P>PROBLEM TO BE SOLVED: To reduce rear side image suppressing variance of color balance for an image forming apparatus.  <P>SOLUTION: A character region extractor 22 and a dot-point region extractor 24 respectively extract a character region and a dot-point region from a draft image 100. A general discriminator 26 generates a region discrimination signal 110 which shows that each region of the draft image 100 belongs to a character region, a dot-point region, or a non-character/non-dot-point region based on the extraction region. A false half-tone processor 12 applies a high line number screen for the character region of the draft image 100, and a low line number screen for the dot-number region, and applies a more higher line number screen than the dot-point region for the non-character/non-dot-point region. Because the rear side image region generally belongs to the non-character/non-dot-point region, the high line number screen is assigned for it. Responsibility of an image output apparatus 14 for the electronic photographing system is lower if line number of the screen is higher, printing density of the back-copying region becomes low. The color-balance does not change because the character region and the dot-point region are as the same to the former conditions.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
