Title: Method of manufacturing information recording medium
Inventor: MASUHARA SHIN
IPC: G11B7/26
Filed: 1999-10-08
Abstract: PROBLEM TO BE SOLVED: To make the pit finer than heretofore and to make the pit pattern density higher. SOLUTION: In forming pit string patterns, a photosensitive layer is exposed by a first light spot which exposes the pit patterns and a second light spot which exposes grooves partly overlapping the side parts of the pit patterns apart a distance of approximately n/2 (where n is an integer) of the track pitch in the radial direction from the first light spot. When the groove width in the sectional shape of a trapezoidal shape in the radial direction of the grooves is given as the mean value of the upper base and lower base of the trapezoidal shape at this time, its value Wg is so set as to attain T.Px0.50<=Wg<=T.P×0.60 with respect to a track pitch T.P.  When a substrate is directly etched, the width Wa at the boundary between the photosensitive layer and a supporting body corresponding to the grooves prior to etching is so set as to attain (T.P×0.50)-45 nm<=Wa<=(T.P×0.60)+45 nm with respect to the track pitch T.P. In either case, the surface of the photosensitive layer is preferably subjected to a hardly solubilizing treatment by immersing the surface into a developer prior to the exposure stage.

Title: Data imprinting device
Inventor: AMANO KENICHIRO
IPC: G03B17/24
Filed: 1986-12-05
Abstract: PURPOSE:To imprint data at all times without character blurring by matching the time required for imprinting with the film speed at the time of the imprinting even when the film speed increases suddenly. CONSTITUTION:A low-speed instructing means 206 detects whether or not the imprinting time required by a data imprinting means matches with the current film moving speed from whether or not the period of one pulse from, for example, a film position detecting means 202 is longer in time interval from a specific period. Then when it is judged that the time interval is longer than the specific period, namely, that the film speed is too fast to match, it is judged that character formation is not performed normally and a decrease in the film moving speed is instructed to a film driving means 201 to reduce the moving speed of the film. Consequently, even when the film moving speed decreases suddenly in the middle, a series of data is imprinted normally by the imprinting control means 203 and the data imprinting means 205.

Title: Circuit for discrimination high-definition television signal
Inventor: MASUMOTO TAKAHIKO
IPC: H04N7/015
Filed: 1987-11-16
Abstract: PURPOSE:To attain accurate discrimination without being affected by noise by deciding a signal as a high-definition TV signal only when the detection pulse of a frame synchronizing signal is detected consecutively for a prescribed time. CONSTITUTION:One UP-count pulse (b) is given to the gate 11 of two AND gates 11, 12 for one frame in the reception of an HDTV signal and two DOWN- count pulses (e) are inputted to the other gate 12. Since the AND gate 12 is set by a decoder output Q0 only when the count of the counter 13 is logic '1', the counter 13 repeats the state of counts '0', '1'. Thus, a discrimination output terminal 15 is kept to the state of '0' and it is discriminated to be the reception state of the HDTV signal.
