Title: Production of nitride ceramics
Inventor: UEDA SHUSAKU
IPC: C04B41/53
Filed: 1988-03-31
Abstract: PURPOSE:To obtain nitride ceramics, containing reduced grain boundary phase components and improved in characteristics, by forming a mixture of a nitride ceramic raw material powder with sintering assistant powder, sintering the formed compact and heat-treating the resultant sintered compact in a gas atmosphere containing a substance opposite to the grain boundary phase components of the above-mentioned sintered compact. CONSTITUTION:Nitride ceramics, e.g., AlN, is produced by the following procedures. That is CaCO3 as a sintering assistant is added to AlN powder and homogeneously mixed in ethanol. Stearic acid as a binder is then added to the above-mentioned mixed powder and pressurized to prepare a disklike compact. The afore-mentioned compact is subsequently heated in a graphite crucible at 500 deg.C to remove the binder. The resultant compact is then sintered in N2 atmosphere. The obtained compact is subsequently heat-treated in a component opposing grain boundary phase substances of the above-mentioned compact, e.g., CF4 gas atmosphere, at a sufficiently higher temperature (e.g., 1600 deg.C) than ordinary temperature to provide nitride ceramic, i.e., AlN. The resultant AlN has high thermal conductivity and excellent in bending strength.

IPC: G03G15/01
Filed: 1981-05-26
Abstract: PURPOSE:To eliminate the need for any retreating mechanism for a transfer drum as against the traveling of an image carrying plate by notching a part of a drum-like transfer body of a transfer device which transfers sensible images to transfer paper. CONSTITUTION:A transfer drum 34 is formed with a conductive drum cylinder 334 of Al, etc. in the central part thereof and an elastic insulator 345 provided on the outer side surface by baking, for example, silicone rubber or the like to about 0.5-10mm. thicknesses thereto. It is provided with a notch 34c made by cutting off the cylinder thereof to about 5-10mm. radially at the plane at a right angle to the radius. This notch 34c contributes to generation of a spacing by as much as it is cut between track W-W' because the drum 34 turns freely by gravity and stops by directing the notch 34c upward when the drum 34 is released from driving forces. Therefore, in the stage of moving an image carrying plate back and forth, there is no need for providing a retreating mechanism between the image carrying plate and the transfer drum, and the generation of color deviation by the retreat operation is averaged.

Title: Thin film transistor matrix having wiring for discontinuity restoration and discontinuity and short-circuit restoring method
Inventor: SANADA TATSUYUKI
IPC: G02F1/1345
Filed: 1996-04-03
Abstract: PROBLEM TO BE SOLVED: To enable the propriety judgment of a discontinuity restoration to be judged by using the same software as a software for discontinuity and short-circuit inspection by connecting bus lines every other line to sides placed opposite to each other of the peripheral connection surrounding respective bus lines and connecting wirings for discontinuity restoration to the peripheral connection via resistors. SOLUTION: Bus lines 1 are connected every other line to sides placed opposite to each other of the peripheral connection 2 surrounding respective buss lines and also wirings for discontinuity restoration 3 are connected to the peripheral connection 2 via resistors 4. Then, when the resistance value of the resistor 4 is defined as Rr and the resistance value of the bus line is defined as Rd , the resistance between terminals 6 after a discontinuity restoration is observed as Rr /2+Rd by connecting the wirings for discontinuity restoration 3 to the connection 2 via resistors 4 in such a manner and since it becomes a value different from the measured resistance value Rd at the time of the short-circuiting of the layer or a high rsistance at the time of the disconnecting of the layer,  a fair that it is mistaken for the short-circuit of the layer is extinguished even though the same judgment software is used.

Filed: 1983-05-09
Abstract: PURPOSE:To obtain a supersonic combustion device, which enables to realize uniform blue flame combustion, by a small sized structure wherein a guide space and a conical roof are arranged in a passage of the air and fuel. CONSTITUTION:A guide member 6 partitions a guide space 8 by being positioned in the relationship to coincide the axis line of the member 6 with that of a vessel 2. Airy swirling flow 26 is produced in the guide space 8 with regard to all the air introduced in an interior space 14 in order to favorably mix with fine atomized fuel in the guide space 8 at the lower end of a roof 12. Uniform blue flames 28 can be formed at the upper part of slits 19 by leading said resultant mixture out of a gap 11 between the roof 12 and the guide member 6. Because the roof 12 has a shape convexed upwards and is installed at the position so high as to be directly striken by liquid column 22, the height of a burner is made smaller. In addition, the fuel 27, which is scattered upward without being finely divided from the liquid column 22, is rendered to adhere to the roof 12 and to be recovered along the inner peripheral wall of the guide member 6.

Abstract: PURPOSE:To obtain a high-performance copying machine excellent in reproducibility and workability by providing the copying machine with an exposure means, an AC pulse applying means, a prescribed EL element, and a photosensitive body. CONSTITUTION:The copying machine is provided with the exposure means 14, the AC pulse applying means 51, the EL element, and the photosensitive body 52; the exposure means 14 exposes the EL element based on the picture of an original 32; the AC pulse applying means 51 applies a AC pulse to the EL element; the EL element emits light with brightness matching the intensity of exposure light when exposed with the AC pulse of a prescribed voltage applied, and maintains the light emitting condition even after exposure is finished; and the photosensitive body 52 is exposed with light emitted by the EL element, and forms an electrostatic latent image. The EL element is cylindrically formed on the surface of the EL element drum 35. In this constitution, since the EL elements stores an original picture in one exposure, an electrostatic latent image can be formed on the photosensitive body by exposing the photosensitive body 52 via a lens 52 with the picture light. Thus, a number of copy papers can be obtained from one original, and copying can be efficiently performed even if the number or originals is large.
