Title: Luminance signal processor
Inventor: NAKAGAWA YUKIO
IPC: H04N9/79
Filed: 1988-11-25
Abstract: PURPOSE:To attain small size and low power consumption by allowing a pre- stage 1H memory in two 1 horizontal period (1H) memories forming a comb-line filter to act like dropout compensation at the same time. CONSTITUTION:A 1H memory 1 stores an input luminance signal Y; by 1H to inhibit data write when a signal DOP representing dropout of the input luminance signal Y; is inputted. That is, the stored 1H preceding data is read at an output of the 1H memory 1 normally but the data before occurrence of dropout is left by 1H in the occurrence of dropout, the data is repetitively read at 1H period and a data Y1 subjected to dropout compensation is outputted. A 1H memory 2 outputs an output of the 1H memory 1 with further 1H delay. Since the memory circuit by 2H acts like dropout compensation of a luminance signal at the same time in this way, small size and low power consumption are attained.

Title: Halftone phase-shift mask, blank for it, and manufacture of halftone phase-shift mask
Inventor: YAMADA YOSHIRO
IPC: G03F1/32
Filed: 1994-11-07
Abstract: PURPOSE: To enable high-definition patterning on a halftone phase-shift mask by preventing a substrate from being electrified when a resist is being drawn by electron-ray exposure and to simplify the processes required to complete the phase-shift mask. CONSTITUTION: A halftone material film 2 and a resist film 3 are stacked on a substrate 1 to fabricate a blank 7. The halftone material film 2 is formed by a two-layer structure comprising a nonconductive MoSiON film 5 and a conductive CrO film 6. With the two-layer structure maintained, the thicknesses of the films 5, 6 are adjusted so that the film 2 can have the desired transmittance as a halftone material. The conductive film 6 prevents the substrate 1 from being electrified during electron-ray exposure that is performed for the patterning of the resist film 3. Etching is carried out with a resist pattern 3a as a mask to form a phase-shifter pattern 2a, thereby completing a halftone phase-shift mask 8.

Filed: 1989-11-17
Abstract: PURPOSE:To attain smooth acceleration and deceleration by driving a motor based on the result of a fuzzy logical operation using rotation information on a tape supply reel and a tape take-up reel and information on tape tension. CONSTITUTION:A supply reel rotation detection part 3 and a take-up reel rota tion detection part 6 detect the period of a frequency which changes by the revolving speed of the supply reel 1 and that of the take-up reel 4 and they supply it to a logical operation part 9. A tension addition detection part 8 supplies the tension value for a tape 7 to the part 9. The part 9 executes the fuzzy logical operation by using the revolving period of the reel 1 detected by the part 3 and that of the reel 4 detected by the part 6, and the tape tension value detected by the part 8. A impression voltage obtained by the operation is impressed on a motor 2 or a motor 5 through a motor driving part 10. Thus, the fast-forwarding and rewinding of the tape 7 can be executed by appropriate tape tension.

Abstract: PROBLEM TO BE SOLVED: To enable fade-in and fade-out with one unit of apparatus, at the time of deleting the data recorded between designated two positions, by reading, from the recording medium, the data corresponding to the address isolated in the constant distance from the addresses of two positions, and then over-writing, on the position before the process of recording medium, the processed data. SOLUTION: When the positions A, B of the recording area of unwanted audio signal in the 98th track are designated, a recording and reproducing apparatus calculates the address of positions C, D before and after the times T1, T2 from the positions A, B and divides the 98th track to the 98th to 102nd tracks with the addresses of the positions A to D. The audio data recorded in the 99th and 101st tracks is faded in the faded out to over-write the data in the position of the original audio data. Next, the 100th track is detected by setting the point of the 100th track in the management list for the track management to zero. Next, the pointers of the 99th, 101st and 102nd tracks are set to zero.

Title: Photosensitive recording medium
Inventor: SANKOCHI TOSHIO
IPC: G03F7/00
Filed: 1986-12-16
Abstract: PURPOSE:To obtain a photosensitive recording medium having high photosensitivity by making the surfaces of the outer walls of microcapsules uneven. CONSTITUTION:When a photosensitive recording medium for forming a pattern by exposure is obtd. by using microcapsules 5 contg. a photosensitive substance, the surfaces of the outer walls of the microcapsules 5 are made uneven so as to increase the surface area of the microcapsules 5. The quantity of light received by the microcapsules 5 is increased by the increased surface area, so the photosensitivity of the recording medium can be enhanced. Since the photosensitivity is enhanced, a light source emitting a relatively small quantity of light can be used as a light source for the recording medium. The photosensitivity of the recording medium can be easily changed by changing the degree of the surface unevenness of the microcapsules 5.

Title: Separation of floating powder dust
Inventor: ODA TOSHIO
IPC: B03B5/44
Filed: 1987-11-30
Abstract: PURPOSE:To collect powder dust within a short time by dispersing the powder dust in a dispersing solvent; 1,1,2,2-tetrachloroethane, and then separating in liq. phase while setting the sedimentation time of the solvent >=100min. CONSTITUTION:A floating powder dust is dispersed in a dispersing solvent; 1,1,2,2-tetrachloroethane, and then the solvent is separated in liq. phase while its sedimentation time is set >=100min so as to separate the powder dust according to the diameters. In the method, because 1,1,2,2-tetrachloroethane instead of water is used as a dispersing solvent, that means larger specific gravity and smaller viscosity than water, separation speed of the powder dust is made higher and separation time is shortened. Thus, for example, a powder dust with <=7mum diameter and harmful for human bodies is separated within a short time.
