Title: Writing method of eprom
Inventor: NAKANO RIKIZOU
IPC: G11C29/56
Filed: 1983-06-17
Abstract: PURPOSE:To shorten the writing time by discontinuing the reading cycle and having the next writing cycle in case a defective result is obtained for reading and collation before the write/read repeating frequency reaches a set level. CONSTITUTION:A control part 10 performs writing to EPROM21-n in response to the write data held at an output part 13 as well as a control program. In a reading cycle, a register 15 is reset by the same address and then the elements 21-n are selected successively by a counter 12. This read data is collated with the original write data. When a defective result of collation is obtained, the collation is discontinued for the defective element and its subsequent ones. Then the reading cycle is stopped, and a writing cycle of the same address is carried out. Thus the undesired collections are excluded. In such a way, the write/read cycles are repeated. Then the additional writing is carried out when a nondefective result is obtained with all of elements 21-n or said write/read cycle repeating frequency reaches a set level. Then the write/read cycles are carried out in the next address.

Abstract: PURPOSE:To reduce scattering of unreacted char and improve efficiency of gasification, by providing a flow path communicated to a reaction tower, in the surrounding wall of a combustion zone and by making the diameter of the tower above the inlet opening larger than that below the inlet opening. CONSTITUTION:As particles of coal or char to be gasified and steam as gasifying agent are fed into a reaction tower 1 through inlet openings 6 and 7, respectively, a gasifying zone 11 is formed in the tower 1 by fluid layer reaction of coal particles, etc. and produced gas is sent out through an outlet opening 8. The reacted coal particles in the gasifying zone 11 is stored at the bottom of the reaction tower 1 to form a transit layer 12. When air is supplied through an inlet opening 9, coal particles in the transfer layer zone are sent into a combustion tower 2 and a part of the carbon burns in a combustion zone 3 by fluid layer reaction to cause heating of the coal particles. High-temp. particles come down because of a sudden decrease in gas flow rate in a vacant zone 4 and are circulated into the reaction tower 1 through an overflow zone 5 for gasification reaction in the gasifying zone 11.

Title: Display device
Inventor: MORITA KATSUHIKO
IPC: G09G3/28
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To reduce the loss of gradation information due to an inverse gamma correction and also to reduce pseudo contours in a moving picture by increasing displayable number of gradations and converting digital data into those having an increased number of gradations at the time of applying the inverse gamma correction conversion to the data. SOLUTION: The video signal inputted from an input terminal 1 is converted into 8-bit digital data at an A/D converting part 3 and the data are subjected to a code conversion to become 9-bit digital data at a code converting part 4. The code converting part 4 codes the data by expressing the converted result of having gradations larger than the gradations of the data outputted from the A/D converting part 3 while performing the inverse gamma correction. As a result, the loss of gradation information in low luminance areas due to the inverse gamma correction is made small. Moreover, pseudo contours of the moving picture in a halftone are reduced by coding the data so that an added subfield surely emits light in the intermediate part between the gradations.

Abstract: PURPOSE:To improve the accuracy in forming a magneto-resistance effect element MR and to reproduce faithfully recorded information, by making the distance up to the juncture of the line where said element contacts with a recording medium and an electrode larger than the magnetic sensing part of the element. CONSTITUTION:When a recording medium 11 is slid with respect to an MR element 8, the electric resistance of the element 8 is changed by the magnetic field generated by the information recorded on the medium 11, and the information stored on the medium 11 is reproduced. The shape and position relation of the element 8, electrodes 9, a biasing current path 12 and a shielding layer 15 is so constituted as to obtain the relations l>Sw, l>B, l>Sh where the length from the forward end of the element 8 on the recording medium side up to the position where the same is connected to an electrode 2 is designated as l, the stripe width of the element 8 as Sw, the width of the path 12 as B and the width of the layer 15 as Sh, respectively. Since there are no electrodes of the film thickness larger than the MR element in the forward end part of the MR head as mentioned above, the width of the gap between the MR element and the shielding layer and the insulation layer are made equal, whereby the width of the gap is decreased and the resolution of the shielding layer is improved.

Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To obtain a vaso-occlusive device that can be easily delivered to a distant and curved portion of a tissue of a human body and has excellent thrombus-forming property by providing the base with a heat supply source for generating heat to secure fiber to the base. SOLUTION: Fiber 12 is arranged between the windings of coil 11 at predetermined intervals along the longitudinal direction of coil 11 and substantially vertical to the longitudinal axis (14, 15) of coil 11. A mandrel 20 used as a heat supply source extends through the inner cavity 16 of coil 11 to exceed the ends 17, 18 of the coil 11. A voltage V of about 2 to 3 volts is applied as transversing the length of mandrel 20 containing the length of coil lumen 16 thus generating a current of about 0.25 to 0.40 amps. The generated current heats the mandrel 20 to cause the deformation of fiber 12 in the inner cavity of coil 11. Therefore, when the mandrel 20 after the thermal deformation process is drawn out of the coil 11, the fiber 12 is secured to the coil 11 so as to prevent the same from being lost.

Abstract: PURPOSE:To obtain an extremely excellent flat surface by providing a flat layer on an insulating layer and subjecting the flat layer and insulating layer to nonselective etching using ion beams when forming a groove as a semiconductor substrate, coating the full surface with an insulating layer including the groove and burying the  groove with the insulating layer. CONSTITUTION:An inverse conductive type layer 2 is epitaxially grown on one conductive type Si substrate 1, and a groove of a V-shape or the like intruding in the layer 2 up to the substrate 1 is formed using an anistropic etching solution. Then, the full surface of the groove is coated with an SiO2 film 3 so as to be used as an isolation region, and a polycrystal Si layer 4 which is used as an insulator by lamination, is stacked on the above SiO2 film 3. Thereafter, the layer 4 is caused to remain only within the groove by grinding or the like and the other part is eliminated to flatten the surface. By said procedure, the surface is discontinued and is not flattened. Accordingly, a flat layer such as a photoresist or the like is formed, and subjected to nondestructive etching to cause the layer 4 to remain only in the groove, and used as an isolation.
