Title: Conductive paste and plasma display using the same
Inventor: KISHIMOTO TAKEHIDE
IPC: H01J17/49
Filed: 1991-06-07
Abstract: PURPOSE:To provide high conductivity and adherence by forming the surface of a cathode conductive material with conductive powder paste covered with such material as suitable for baking at a temperature equal to or below the baking temperature of the conductive material. CONSTITUTION:Titanium nitride powder is covered with nickel alloy containing silicon, using an electroless plating method. The melting point of the alloy comprising silicon added to nickel drops to a level below the melting point of nickel proper. A glass binder having a low melting point and an organic binder are added to the powder, thereby preparing conductive paste. Then, nickel paste as conventionally used is screen printed on a glass substrate 1, thereby forming a cathode pattern. Thereafter, the titanium nitride powder covered with the nickel alloy is laminated on a nickel cathode 2 and baked, thereby forming a titanium nitride cathode 3 covered with the nickel alloy. The cathode 3 covered with a nickel alloy layer 4 is etched and as a result, the surface of titanium nitride 5 comes to be exposed on a cathode surface.

IPC: B28B3/02
Filed: 1993-05-15
Abstract: PURPOSE:To simply produce a tile of good quality in a high yield and to reduce the heavy labor of a worker and the load to a structure by subjecting a powder raw material to compression molding to form a groove with a predetermined width on the rear of a tile material and cutting the side surfaces of the groove by a rotary cutter to form a dovetail groove. CONSTITUTION:The cavity of a powder compression molding apparatus 5 constituted of an upper mold 2, a lower mold 3 and a form 4 is filled with a powder raw material and this raw material is molded into a rectangular plate-shape tile material 8 by the compression action of the upper and lower molds 2, 3. At this time, a groove 12 with predetermined width is formed on the rear 9 of the tile material 8 by the projection 11 formed to the molding surface 10 of the upper mold 2. After the completion of a compression or drying process, an appropriate rotary cutter having a proper shape, for example, an almost truncated cone shape is moved along the groove 12 from one end part thereof to the other end part thereof at an appropriate speed to obliquely cut the opposed side surfaces of the groove 12 and the groove 12 is formed into a dovetail groove by the side surfaces and bottom part of the groove to obtain a tile.

Abstract: PURPOSE:To facilitate the grasp of the conductive time of an electric circuit and to simplify constitution by measuring the operating time of the electric circuit and flashing a lightemitting element by means of a pulse signal in one period, which corresponds to a measured value. CONSTITUTION:When an oscillator 8 in a control circuit 5 receives a driving voltage V from the electric circuit 3, it gives the clock signal of a prescribed period to a counter 7 and the counter 7 measures the number of operating hours of the circuit 3. The added value is given to a waveform generator 9, which operates the outputs of the counter 7 at every clock signal and allocates respective time widths of 'H' and 'L' to the pulse signal in one period. The generator 9 outputs a continuous pulse signal based on the pulse signal in one period. The pulse signal is given to the light-emitting element 4. At the time of 'H', the element 4 is lighted, and it is lighted out at the time of 'L'.

IPC: G06K9/00
Filed: 1979-10-24
Abstract: PURPOSE: To reduce misreading by providing two or more preprocessing parts differing in system and by independently recognizing preprocessed character patterns.  
     CONSTITUTION: Character patterns stored in buffer memory 3 are processed by preprocessing parts 8 and 9 on different systems that cover their weak points mutually and sent to pattern memories 10 and 11 respectively.

Next, final decision part 14 checks the contents of buffers 12 and 13 and decides the final output on the basis of prescribed logic. Namely, only when both the recognition results show say the same category name, the category name is regarded as the final output and when not, information showing discard is sent out as the final output. Thus, misreading can be reduced.

Title: Method and device for coating printing screen
Inventor: RUDORUFU GATSUSAA
IPC: G03F7/12
Filed: 1980-10-01
Abstract: Flat printing screens can be coated on one or both sides by the method and apparatus. A liquid is applied to a screen by one or two squeegees secured to carriages moved up and down on rubber sprocket belts driven by a motor. The speed of application can be adjusted according to the desired thickness of the coating and the viscosity of the liquid. The squeegees are mutually offset somewhat in height to reliably prevent the liquid from running out when the squeegees are not in motion. Application takes place regularly and reproducibly even in the case of a thick coating. The drive by means of rubber sprocket belts and a counterweight ensure vibration-free movement of the squeegees along the screen.

Abstract: PURPOSE:To shorten the time for production and to allow the reading out of images with a high resolution by constituting a photoconductor of a 1st photoconductive layer for charge generation and a 2nd photoconductive layer for charge transfer utilizing a high-polymer material. CONSTITUTION:The photoconductor 46 formed on the writing light incident side of the optical modulator 40 is constituted of the 1st photoconductive layer 46A and the 2nd photoconductive layer 46B. The 1st photoconductive layer 46A consists essentially of, for example hydrogenated amorphous silicon and acts mainly as a carrier generating layer. On the other hand, the 2nd photoconductive layer 46B consists essentially of the tetranitrofluorefin dispersed in a polymer and acts mainly as a carrier transfer layer. The time for the film formation of the photoconductor is made shorter than in the case of the amorphous silicon alone and is formed to a larger area. Further, the volume resistivity of the 2nd photoconductive layer is high and, therefore, the charge images are well maintained and the high resolution of the reading out images is obtd.
