Title: Print controller
Inventor: SUZUKI EIJI
IPC: G06F3/12
Filed: 1989-02-22
Abstract: PURPOSE:To attain a normal printing operation even though the density of the input image data is different from the printing density of a printer by deciding the density of the input image data and changing the density of the print image data in order to secure the coincidence between the density of the input image data and the printing density of the printer. CONSTITUTION:A density deciding part 6 decides automatically the density of the input image data from the main scanning direction and the subscanning frequency of the input image data. Then the part 6 compares the density of the input image data with the printing density of a printer 5 and reports this density information to a density conversion part 7. The part 7 converts the print image data received from an arithmetic processing part 2 into the double density in both main and subscanning directions respectively based on the density information. Thus the new print image data is produced with (m) dots in the main scanning direction and (n) lines in the subscanning direction. As a result, a normal printing operation is attained even though the density of the image data is different from the printing density of the printer 5.

Title: Semiconductor crystal growing method and semiconductor manufacturing device
Inventor: MIYAMOTO YASUMASA
IPC: H01L21/20
Filed: 1995-02-28
Abstract: PURPOSE: To form a polysilicon thin film composed of crystal grains having high uniformity of grain sizes by deciding the size of crystal areas based on the thickness of an amorphous semiconductor thin film so that one crystal nucleus can be formed in each crystal area and selectively imparting crystallizing energy to the crystal areas having the decided size. CONSTITUTION: An amorphous silicon thin film 2 having a thickness of 100nm is deposited on an insulating substrate 1 formed by depositing a silicon oxide film on the surface of a silicon substrate by using the LPCVD method. The thin film 2 is irradiated with a laser beam 3 shaped so that the diameter of the beam 3 can become about 100nm on the surface of the substrate 1. It has been learnt from tests carried out by changing the thickness of the thin film 2 in various ways that crystal grains of a uniform diameter can be obtained when crystal nuclei are formed in areas having sizes which are equal to or smaller than the five time of the thickness. Since the diameter of the laser beam 3 is made nearly equal to the thickness of the thin film 2, crystal nuclei 4 composed of single crystal grains are formed in the area irradiated with the beam 3.
