Title: Method for recovering magnetic film from magnetic recording medium
Inventor: KAMEYAMA KAORU
IPC: B29B17/02
Filed: 1992-12-14
Abstract: PURPOSE:To efficiently recover a magnetic film by bringing a magnetic recording medium obtained by applying a magnetic powder and a binder resin on a substrate to form a magnetic film into contact with liq. pyrolidone or gamma- butylolactone stripping the magnetic film from the medium. CONSTITUTION:A magnetic film is stripped from a material to be discarded. In this case, liq. pyrolidone or gamma-butylolactone is brought into contact with a substrate and infiltrated into the interface between the substrate of polytetraethylene terephthalate and the magnetic film by sonic cleaning, vibration, spraying, etc. Even when the coating film of the magnetic film is hardly released, the magnetic film is easily stripped by lightly rubbing the filmy material to be discarded with a nylon brush, etc.

Filed: 1996-12-13
Abstract: PROBLEM TO BE SOLVED: To eliminate the shortage of ink chambers by setting a hole-shutting layer all over a side wall of an ink-absorbing body with leaving a part without the hole-shutting layer at a lower part. SOLUTION: An ink cartridge is constituted of an ink-absorbing body 9 in which a hole-shutting layer 9a prohibiting the penetration of ink is formed at a part of a side face, and a rib set for positioning the ink-absorbing body at a boundary between an ink chamber 4 and a negative pressure chamber 6 and having an ink passage 12 at a lower part thereof. The hole-shutting layer 9a works in place of a diaphragm generally provided at the boundary of the ink chamber and negative pressure chamber 6. Minute through holes present at a surface of the ink-absorbing body 9 are shut by pressing with heat the side wall of the ink-absorbing body 9 of urethane or the like, thereby preventing an ink 3 from entering the negative pressure chamber 6.  The ink is absorbed into the ink-absorbing part 9 through the passage 12 from a part without the hole-shutting layer 9a which is left at a lower part of the ink- absorbing body 9. That is, since the diaphragm is eliminated, a capacity of the ink chamber 4 is increased.

Abstract: PURPOSE:To simplify a circuit by supplying the information of a video system to a CCD and switching the step number of the CCD to match with the 1H of the video system. CONSTITUTION:Video signals are inputted from a video input terminal 1 and supplied to a CD block 2.

On the other hand, at the block 2, the information of the PAL is received, the step number of the CCD inside is switched so as to match with the 1H of the PAL and the 1H delay signals of the PAL are outputted. Then, when the information of an NTSC system is inputted to the terminal 4, the signal processing of the NTSC system is performed at the block 5, FSC=3.58 MHz is outputted and the processing similar as above is performed. Thus, the 1H delay signals optimum for both NTSC and PAL systems can be obtained from a video output terminal 3.

Title: Reflection type mask substrate
Inventor: YANO KICHIYA
IPC: G03F1/24
Filed: 1995-11-28
Abstract: PROBLEM TO BE SOLVED: To make a mask substrate almost independent of the environment at the time of producing a mask and thermal and chemical changes in an exposure system and to enhance the precision of exposure by forming a specified SiC film on a sintered SiC sheet as a substrate. SOLUTION: A thin SiC film 2 is formed on a sintered SiC substrate 1 and the surface of the film 2 is mirror-polished to obtain the objective mask substrate. The film 2 is a (220) face oriented thin SiC film having a β-crystal structure and excellent in workability and polishability. In the X-ray diffraction of the film, the diffraction peak of the (220) face has the max. intensity. In the case of an X-ray diffraction peak ratio of >=99, the mask substrate enables the transfer of a precision pattern for exposure to the top of a wafer.  Since both the substrate 1 and the film 2 are made of SiC having a low coefft. of thermal expansion, inter-facial peeling is hardly caused and a mask pattern on the specular surface 3 of the film is not deformed by the thermal strain of the substrate in the environment at the time of producing a mask and causes no trouble to the top of a wafer to which the pattern is transferred.

Title: Method for drying wet powder
Inventor: YAMADA MITSUNORI
IPC: F26B3/088
Filed: 1991-11-26
Abstract: PURPOSE:To obtain the powder having a small particle size in diameter and reduce the energy required for driving a hot air blower and a stirring blade necessary for drying the powder. CONSTITUTION:A hot air is blown into a drying container 2 at such a speed as not to entirely fluidize powdery drying medium 1 and the powder is stirred by a stirring blade 3. This eliminates the need for delivering a strong hot air and, since the powder transfer force of a hot air exhaust stream is not so strong, the powder having a relatively small particle size alone can be drawn out, and the powdery drying medium 1 is not entirely subjected to a violent fluidization and, therefore, the stirring action of the stirrer 3 is not hindered.
