IPC: G06F17/50
Filed: 1981-10-30
Abstract: PURPOSE:To pick up a line drawing only, by detecting a background area other  than a part corresponding to the internal side of a closed drawing from a drawing scanned and sampled in two-dimension lattice shape and taking logic operation between the background area and the sampled drawing. CONSTITUTION:A pattern design drawing 101 of a printed wiring board is scanned in two-dimension lattice shape for quantization sampling. A sampled drawing 201 of the background area eliminating closed drawings 1021-1029 from the drawing 101 is formed. The drawings 101 and 201 are logically processed to pick up line drawings 1031-1036 from other drawings separatingly. Thus, the automatic reading processing only for line drawings can very easily be executed.

Title: Disk apparatus
Inventor: SAKAI JUNICHI
IPC: G11B21/10
Filed: 1994-07-26
Abstract: PURPOSE:To perform a stable tracking pull-in by detecting external vibration even when the tracking servo of a disk apparatus is opened. CONSTITUTION:The change of a tracking error signal A due to the eccentricity of an optical disk 1 or an external vibration is turned into pulse by a comparator 6. In this case, first and second pulse interval detecting means 7, 8 set the output of the comparator 6 to 'H' and input it to an MPU 9 when it is shorter than a set time T1 and longer than a set time T2. The MPU 9 detects that the vibration is applied, and controls a tracking servo changeover switch 10. Since the MPU 9 can measure the time when the input signal becomes 'H', it operates as pulse width detecting means for detecting that the Q output of a D flip-flop 7b of the first means 7 becomes the set time 'H'.

Abstract: PURPOSE:To prevent the generation of an optical noise by arranging many grooves with depths to dissipate a light in the polarizing direction to be the same direction as a width direction and forming surfaces so as to be inclined to the surfaces of the grooves. CONSTITUTION:A substrate 10 is made of a material to attenuate a light in the range of the wavelength of the light to execute an irradiation and, simultaneously, to have a prescribed refraction factor. To the substrate 10, a groove 11 with a width W to be narrower than the wavelength of 1/2 of the wavelength of the light to execute the irradiation and with a depth (d) is formed, and moreover, it is arranged in a large number at a pitch P interval. The depths (s) of the grooves 11 are formed so as to be successively shallow, and thus, a surface 12 of a polarizer is formed in being inclined at an angle theta to the bottom surface of each groove 11. For such a reason, each groove 11 is made to work as a waveguide, a light P2 to be linearly polarized and a light P3 in the polarizing direction except it are reflected, and the proceeding directions of the lights P2 and P3 are completely different. Thus, even at the time of light-receiving the light P2 to be linearly polarized, the optical noise cannot be generated.
