Inventor: NAKANISHI MASAYUKI
IPC: H01J31/15
Filed: 1998-04-21
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of a warp on a display screen by separately forming transparent protection films each formed to cover the exposed region of an optical filter. SOLUTION: A transparent protecting film 101b having insulating property is formed so as to cover the exposed region of an optical filter 104a selectively formed on the inside of a display screen 101 and separate adjacent protecting films 101b each other. A phosphor layer 104b is formed on the optical filter 104a through the protecting film 101b, and a back reflecting layer 104c made of a metal film is formed on the surface of the phosphor layer 104b. An electrode wiring 108 is formed so that the specified voltage can be applied. Since the transparent protecting film 101b is locally formed instead of the whole region of the display screen, even if the volume of the protecting film 101b changes after being formed, a warp on the display screen of a fluorescent character display device is suppressed.  Since the protecting film 101b and the phosphor layer 104b are formed by simultaneous baking, adhesion is enhanced.

Title: Magnetic head
Inventor: TAKAHASHI JUNICHI
IPC: G11B5/23
Filed: 1986-05-16
Abstract: PURPOSE:To prevent mutual diffusion from being caused between a magnetic thin film and glass by forming a nitrided layer at least a part of the surface of a magnetic thin film of 'Sendust(R)' contacting glass for welding core half bodies. CONSTITUTION:The 'Sendust(R)' is formed on a ferrite pipe 7 and then a groove 8 which prescribes track width and a winding window 9 are worked and gas nitriding is carried out in this state. Then, SiO2 for specifying a gap is sputtered on the 'Sendust(R)' film 2 and the pieces are made to abut on each other and welded with glass. Then, the united body is cut to specific size to obtain core half bodies, thus forming a magnetic head. No mutual diffusion between the glass and 'Sendust(R)' film is caused even when the glass welding is performed after the nitrided layer 10 is formed. In this case,the 'Sendust(R)' film is easily peeled off the ferrite at temperature above 650 deg.C, so the treatment temperature should be lower than 650 deg.C at the time of the surface treatment.

Title: Double detecting method and circuit thereof for measured object of paper or the like
Inventor: ASAI MASANORI
IPC: B41F33/14
Filed: 1990-04-25
Abstract: PURPOSE:To set an optimum discrimination level relating to a measured object by adjusting an output from a light receiver, related to a reference measured object, to a predetermined level in a condition that a quantity of light of a light projector is fixed thereafter by detecting the measured object. CONSTITUTION:First, paper P, which serves as a reference, is arranged between a light projector 1 and a light receiver 2. An amplifier 4 performs I/V conversion to generate an output to an MPU6 by projecting light of fixed quantity by the light projector 1 and allowing a current, in proportion to a quantity of light received through the paper P, to flow by the light receiver 2. An in-flow of the current is generated in the amplifier 4 by outputting a signal to a light receiving current variable amplifier 5 for setting the most efficient range of the amplifier 4 by the MPU6 based on its voltage value. A discrimination level is calculated by calculating an output from the amplifier 4, and an arithmetic result of the level is stored in a memory in the MPU6. Thereafter, a voltage value of an objective measured object is fetched, and when the value is different from the discrimination level, the discrimination result is output by driving an output relay circuit 7.
