Title: Copy and forgery preventing printed matter
Inventor: NAKAMURA HARUMI
IPC: B42D15/10
Filed: 1994-03-31
Abstract: PURPOSE:To allow a copy to be clear at a glance and prevent a forgery by copying by clearly developing a warning image which cannot be identified to the naked eye before copying in a color copy of a wide range from a high density to a low density. CONSTITUTION:A warning image part having a character 2 and a background part having a ground pattern 3 are printed by different screen rulings with inks of two colors such as cyan and magenta on a surface of a base 1 in such a manner that the character 2 part is printed by 65 of screen rulings, the pattern 3 part is printed by 150 of screen rulings with the cyan ink and the character 2 part is printed by 150 screen rulings and the pattern 3 part is printed by 65 screen rulings with the magenta ink. Thus, identification of the character 2 part and the pattern 3 part is difficult to the naked eye. When it is color copied, at least one color of the printed part is developed despite the degree of a density regulation at the time of copying, and the identification of the character 2 part and the pattern 3 part can be performed.

Title: Device and method for reproducing video signal
Inventor: SUZUKI KOJI
IPC: H04N5/783
Filed: 1994-03-31
Abstract: PURPOSE:To prevent the occurrence of a noise bar even if the amplitude level of a reproduced signal is fluctuated by providing an adjacent address comparison means generating a reference level signal based on an adjacent write address signal. CONSTITUTION:The adjacent address comparison means 15 compares adjacent addresses based on the address signal 12a and generates the reference level signal 15a. When write periods are repeated, the reference level signal obtained by raising a level in accordance with the repeated periods is generated. When the write periods are not repeated, the reference level signal obtained by reducing the level in accordance with the period which is not repeated is generated. Thus, the reference level signal 15a generated based on the address where a video signal is actually written into a memory is fed back. Thus, a write area for the memory can be made appropriate.

Abstract: PURPOSE:To reduce unnatural motion which occurs easily during low-transmission-speed television signal transmission by using information showing the best forecasting system obtained by an encoding system which utilizes motion compensation. CONSTITUTION:For the decoding of an encoded field, a forecasting signal generating circuit 33 generates the best forecasting signal by using information showing the best forecasting system and then supplies it to an adder 32.

Title: Method for sealing ceramic molded product
Inventor: DEMURA AKIHIRO
IPC: B28B11/00
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To apply appropriately sealing to an end face of a ceramic molded product by a method wherein after penetrating a sealing paste into a through- hole of the ceramic molded product from a gap of a mask, the ceramic molded product is separated from the mask. SOLUTION: At first a state wherein a ceramic molded product 21 is disposed above a mask 11 is provided. That is, while the mask 11 is stuck close to an end face 21a of the ceramic molded product 21 as it is, a sealing paste discharge tank and the ceramic molded product are rotated so that the ceramic molded product 21 is disposed above the mask 11, and a main face of the mask 11 becomes almost horizontal. Thereafter, the ceramic molded product 21 is separated from the mask 11 (b). In this case, an upper part of a webbing part of a sealing paste 13 becomes thin and therefore, the sealing paste 13 is broken in the upper part. Consequently the sealing paste 13 after end of a separating process is not overly protruded from an end face of the ceramic molded product 21 (c). After end of a drying process, almost the same shape is also maintained.

Title: Image pickup tube
Inventor: KURASHIGE MITSUHIRO
IPC: H01J29/48
Filed: 1981-06-08
Abstract: PURPOSE:To creat an image pickup tube offering extra-high resolution, extremely few residual images, high-density beam current, ling life, high-productivity and low cost by a method wherein electron beams extracted from an electron gun are caused to radially radiate from the cathode and the electron beams radiated are focused on a target through a focusing system. CONSTITUTION:In the drawing, there is shown the cathode 30 for generating electrons, wherein its tip 31 has been sharpened like a pin to obtain high resolution by forming the source of an electron discharge in a dotted state. Moreover, by making the tip 31 in the form of a pin, when the cathode 30 is heated after it has been sandwiched in between pyrolyzing graphite heating bodies 41, heat is seen to be concentrated at the tip of the cathode 30, which is advantageous, so that its electron-discharging assembly is made in a pointed from. In other words, since beams are radially extracted from the pointed cathode, there appears few transition phenomena among electron beams, and it is features that, in comparison with the conventional diode gun with few residual images, the number of residual images becomes fewer. In addition, the higher density of electron current discharged from the cathode is available and, since the divergence angle of the beam is suitable in degree, high resolution as well as uniform resolution are possible.
