Filed: 1987-10-05
Abstract: PURPOSE:To decrease the number of axes, to reduce errors due to a backlash, etc., and to perform tracking with high accuracy by employing an AZ-EL mount system of simple structure for a vertical gyro and a directional gyro. CONSTITUTION:The directional gyro 2 outputs the moving direction 2a of a moving body as a synchro output, which is inputted to a signal processing part 4. The signal processing part 4 inputs the inputs pitch output 1a and roll output 1b of the vertical gyro 1 to correct and calculate an EL direction and an AZ direction based upon a pitch roll angle. Then the signal processing part 4 checks time data from a timer, calculates a drift correction quantity from the time difference from the time when the last drift quantity is corrected to a zero point, and adds the result to the course output of the directional gyro. Thus, the output of the directional gyro which indicates the current direction is obtained to enable an antenna to track a satellite.

Abstract: PURPOSE:To manufacture a hard mask having no pinhole defect at a low cost by exposing and developing again the same pattern using a master mask after coating a transparent substrate surface having a patterned metal thin film with photo resist and carrying out electroless plating with the obtained photo resist pattern used as the plating resist. CONSTITUTION:A mask for exposure generating pinhole 3 at a metal pattern 2 on a transparent substrate 1 is coated with a negative photo resist 4 by spin coating method and this coating is cured. Thereafter, positioning is carried out so that the patterns 2 and 6 are perfectly aligned using a master mask 5 and then exposure and development are carried out using ultraviolet ray (UV). The entire part, except for the resist 4, is coated, for example, with the Sn-Pd catalyst. In this case, the resist 4 is of water repellent and therefore the catalyst is difficult to be absorbed. Even in case the catalyst is a little absorbed and a plating film is precipitated in the following plating process, such film is easily exfoliated when the resist 4 is stripped. Next, the patterned photo resist 4 is used as the photo resist for the electroless plating 7.
