Abstract: PURPOSE: To easily manufacture a matrix wherein a master film sheet is embedded, by forming an optional image or the like on a transparent film to make the master film sheet, placing the sheet in tight contact with a photosensitive resin liquid and irradiating light upon the resin liquid.  
     CONSTITUTION: An optional figure or characters are drawn in Indian ink or optically copied on a transparent film to make a master sheet 3. This sheet is tightly fitted on a light-permeable resin sheet 2. A transparent sheet 4 of very small thickness is tightly fitted on a black glass or resin sheet 7. A frame 6 slightly larger than a matrix is secured. A photosensitive resin liquid 5 is put in. A transparent glass sheet 1 is secured on the light-permeable resin sheet 2 placed in tight contact with the master film sheet 3. This sheet 3 is then located face-down so that it is lightly brought into tight contact with the resin liquid 5. Light is irradiated from light sources 8 upon the resin liquid 5. As a result, the regin sheet 2 and the resin liquid 5 are brought into tight contact with each other. The resin sheet 2 and the resin liquid 5 are thereafter removed from glass. Unhardened portions 9 are washed off. This results in providing the matrix wherein the master film sheet 3 is completely buried.

Abstract: PURPOSE:To improve the accuracy of recovered clock and to prevent deterioration in picture quality by increasing a level of a burst signal more than a level of a video signal in a video tape recorder in which a High Vision signal is FM-modulated and recorded and reproduced. CONSTITUTION:A signal level of a burst signal 6 is set larger than a level of a luminance signal 3 by nearly 18dB and set larger than that of a color difference signal 2 by nearly 12dB. Moreover, a peak level of a horizontal synchronizing pulse 5 is set nearly equal to a negative peak level of the signal 6 or set smaller than that. Thus, when the signal level of the signal 6 is set larger in this way, the S/N at the reproduction of the signal 6 is excellent, the accuracy of the recovered clock is improved and no deterioration in the picture quality of the reproduced picture is caused. That is, a write clock WCK with excellent tracking with respect to jitter of the reproduction signal is produced from a write clock generating circuit 37 of the reproduction section 8 and a same output data as an input data to a D/A converter section 17 of a recording section 7 is obtained from an A/D converter 30.

Title: Stamper for producing substrate of information recording medium
Inventor: USAMI YOSHIHISA
IPC: G11B7/26
Filed: 1991-02-27
Abstract: PURPOSE:To form the substrate which is substantially the same in the depth of grooves in the inner peripheral part and outer peripheral part of the substrate by specifying the height of the projecting lines in the inner peripheral part and outer peripheral part of the stamper. CONSTITUTION:The projecting lines 23A, 23B of a projecting line region 22 provided on the stamper 20 are so formed that the height hB of the projecting line 23 in the outer peripheral part is larger than the height hA of the projecting line 23A in the inner peripheral part of the stamper 20. These lines have such a height which increases linearly from hA to hB from the inner peripheral part toward the outer peripheral part of the stamper 20. Such change in height can be easily formed by changing the light quantity of the laser beam for exposing a resist layer at the time of producing the stamper. The substrate which is substantially the same in the difference in the depth between the inner and outer peripheral parts is produced in this way even if the absolute value of the depth of the grooves is small.

Abstract: PURPOSE:To reduce the irregularity of density or ground fogging by disposing a thin magnetic field generation layer and holding and carrying toner whose electrostatic charge quantity is stable. CONSTITUTION:A developing roller is obtained by forming an elastic layer on the base body 31 of a shaft or the like, forming the magnetic field generation layer 32 on the elastic layer and forming a floating electrode layer, which is dotted with fine electrodes 33, on the magnetic field generation layer 32.

Besides, a uniform and thin toner layer can be formed on the developing roller by executing the magnetization of a fine pitch on the thin magnetic field generation layer 32. Thus, the irregularity of the density caused by the change of a magnetic field or the change of the thickness of the toner layer is reduced and the developing electrode effect of a floating electrode is obtained. As the result, developing with high resolution is realized.

Title: Heat exchanger
Inventor: ITOU MASARU
IPC: F24H3/06
Filed: 1981-04-17
Abstract: PURPOSE:To increase the coefficient of heat transfer on the surface of a heat exchanger, by forming ribs on the surface of fins so that thick boundary layers may not develop on the fin surfaces. CONSTITUTION:On the outer surface of a heat exchanger 1, fins 2 are formed in a unitary manner to extend in parallel to the flow of heat exchanging air flowing on the outside of the heat exchanger 1. Further, ribs 3 are formed on the surface of each fin 2 to extend perpendicularly to the air flow, in the manner that ribs 3 formed on adjacent fins 2 may not face toward each other so as  not to reduct the area of air passages. With such an arrangement, a boundary  layer of air formed from the top end of a fin 2 is ruptured by a first rib 3 and  the surface of the fin 2 is exposed. However, a boundary layer is developed  again on the fin surface at the portion thereof located downstreams of the first  rib 3 but this boundary layer is ruptured again by the next rib 3, so that the  thickness of the boundary layer on the surface of the fin 2 is reduced extremely.  Therefore, it is enabled to reduce the heat resistance between air and fins 2 and  to thereby increase the coefficient of heat transfer appreciably.
