Filed: 1992-07-22
Abstract: PURPOSE:To decrease the track pitch of an optical disk and to produce the master disk for producing a high-density substrate by repeating stages for development processing, washing and drying plural times, thereby forming narrow guide grooves. CONSTITUTION:A photoresist 2 is irradiated with a microspot by zero order diffracted light formed at an ultra resolution and the exposed part of the photoresist by the higher order diffracted light generated simultaneously with the zero order diffracted light is removed by a high-contrast development. As a result, the guide grooves or microprepits of the width narrower than the width of the guide grooves or microprepits limited by the wavelength of the light to be used and the depth down to the middle of the resist are formed. Further, the patterns fiver than the previously obtd. patterns are obtd. by a multi-stage development method. The peripheries of the patterns are smoothed by high-temp. baking, by which the master disk 3 having high quality with decreased noise components is obtd. with the simple method.

Title: Signal reproducing circuit
Inventor: ABE SHIGEO
IPC: H04N9/87
Filed: 1986-08-22
Abstract: PURPOSE:To prevent missing of color even at a small envelope level of a reproducing signal by writing a video signal in a memory when the envelope level of the reproducing signal is a prescribed level or over and extracting a required color synchronizing gate pulse from a luminance signal read from the said memory. CONSTITUTION:Only a video signal whose recovered envelope level is high is written in a picture memory 7 by a write control signal 300. Then the content of the picture memory 7 is read repetitively by a readout control signal 500 and outputted as a video signal 800. Since the video signal 800 is a video signal whose portion with small envelope is eliminated, the noise portion of a chrominance carrier signal 200 and the noise portion of a luminance signal 400 are not included as a complete video signal. Thus, the color synchronizing gate pulse 400 separated from the video signal 800 by a synchronizing separator circuit 4 is a complete pulse without noise portion. Thus, out of synchronism of color is not caused.

Abstract: PURPOSE:To keep off any backflow at a passage conveying a granule by means of gas transportation, by partitioning off a vertical rising part into the top and the bottom each, which conveying the granule with the both lower and upper partition plates where plural holes larger than a diameter of the granule each are formed. CONSTITUTION:Air and granules P being conveyed out of a conveying pipe 6 are entered in a flowing floor part 11 from holes of a lower partition plate 12. When a backflow occurs, a flow of air comes downward, whereby a flowing material 15 is pressed to the lower partition plate 12, precipitated and air flow resistance is remarkably made larger as four at five times over the normal time. Therefore pressure P3 in an inlet adjusting part to be measured by a pressure gauge 17 becomes smaller than pressure P4 in an outlet adjusting part to be measured by a pressure gauge 18, whereby a differential pressure gauge 19 detects this abnormality. This differential pressure gauge 19 operates a solenoid value 22, and feeds inert gas in an inert gas source 20 to the outlet adjusting part 14 via a conduit tube 21 at a rate of m<3>/h in opening number of a valve under condition of pressure P4 > pressure P3.
