Title: Pattern position recognizing device
Inventor: KOGA YASUTAKA
IPC: H05K13/04
Filed: 1988-03-31
Abstract: PURPOSE:To enable the recognition of the position of a pattern for recognizing a position with high accuracy even when HAL processing is executed for a substrate or stain exists on the substrate by providing a scanning means which scans image data obtained by image-pickup to obtain gradation data. CONSTITUTION:An image pattern signal picked up by an image pickup device 2 is converted to the digital signal of plural gradation by an A/D converter 3 and stored in an image memory 5 in an image processor 4. By receiving the instruction of a main control part 6, the scanning circuit 8 sets the respective scanning number of an (x) and a (y) directions based on the image data stored in the memory 5. For example, the scanning number (n) of the (x) direction and the scanning number (n) of the (y) direction are set so that a cross pattern Q is included within the scanning limits. When this setting is finished, the scanning is executed for the (x) and (y) directions in order of 1-n. The result of the scanning is temporarily stored in the memory 5. A pattern extraction part 9 successively reads each gradation data from the memory 5 according to the scanning order and detects two parts where the gradation level is suddenly changed in the gradation data. Then, when the most steep parts (a) and (b) are detected, the width of the cross pattern is judged to exists between a point (Fa) and a point (Fb) in the gradation data (d3).

Title: Digital data recording and reproducing device
Inventor: MAEZAWA YOSHIMASA
IPC: G11B20/10
Filed: 1986-04-08
Abstract: PURPOSE:To quickly record digital data through the use of a cassette tape, etc., and to precisely reproduce recorded data by setting a recording voltage in accordance with the ratio of '0' to '1' in a recorded data pulse train. CONSTITUTION:When a data ratio detection means 2 detects that the ratio of '1' in the data pulse train is higher, the recording voltage of a '0' recording voltage generation means 4 becomes high, and that of a '1' recording voltage generation means 6 drops. If the ratio of '0' in the data pulse train is higher, the recording voltage of the means 4 drops and that of the means 6 becomes high. When recorded data is of '1', a recording voltage selection means 8 selects and outputs the recording voltage of the '1' recording voltage generation means 6. In such a way, the DC level of the recording voltage is shifted so as to reverse the shift of the DC level of a reproduction signal, and the data pulse train is recorded. Then the level of the reproduction signal becomes approximately constant, whereby the data pulse grain can be precisely reproduced from the reproduction signal.
