Title: Converting method of xylene containing ethylbenzene
Inventor: IWAYAMA KAZUYOSHI
IPC: C07C1/00
Filed: 1980-10-09
Abstract: PURPOSE: To isomeize a xylene and convert ethylbenzene into another aromatic hydrocarbon simultaneously, by bringing the xylene containing the ethylbenzene into contact with a mordenite type zeolite containing phosphorus as a catalyst in the presence of hydrogen.  
     CONSTITUTION: A xylene containing ethylbenzene is converted into another aromatic hydrocarbon in the presence of hydrogen. In the process, the xylene is brought into contact with a mordenite type zeolite catalyst, containing phosphorus, and subjected to the ion exchange with hydrogen ions and/or a hydrogen ion precursor. The mordenite type zeolite may be a synthetic, natural substance or a mixture thereof. The synthetic zeolite contains sodium ions and preferably subjected to the ion exchange with calcium ions, and the addition of another rhenium component in addition to the phosphorus preferably promotes the hydrogenation and deethylation.  
     EFFECT: Ethylbenzene can be removed under almost no thermodynamic restriction.

IPC: H01L21/3205
Filed: 1990-05-30
Abstract: PURPOSE:To enable repair of a short circuit fault at a point of intersection without impairing a matrix array, by a construction wherein one of an upper- layer wiring and a lower-layer wiring made to intersect each other in the shape of a matrix is made to have a multiple-line structure in the part of intersection. CONSTITUTION:After a matrix array is formed, resistance between a gate line GL and a drain line DL is measured. When a line whereon a D-G short- circuit fault occurs is confirmed, the part of the line wherein the gate line GL and the drain line DL intersect each other is observed by a microscope or the like and a spot X of occurrence of the defect is fixed. By a laser repair apparatus, subsequently, a laser repair method is applied to the drain line whereon the D-G short circuit spot X is located, a drain line DL1 in this example, out of two drain lines DL1 and DL2, and the drain line DL1 is cut in a part Y. On the occasion, the cut spot Y is set on the opposite sides of the short circuit spot X so that the drain line DL1 including the short circuit spot X is left on the gate line GL when the drain line DL1 is cut. When the short circuit defect is repaired by cutting the drain line DL1 on one side by the laser repair method, accordingly, a state of connection of the drain line DL is maintained by the drain line DL2 on the other.

Abstract: PURPOSE:To memorize the 2-bit information by forming one unit of the magnetic core by piling on two units of the magnetic core featuring the rectangular hysteresis characteristics of different critical magnetic fields to each other, and then to read the information in sequence with supply of the stepped current at the reading time. CONSTITUTION:Magnetic core C is formed by piling on two units of memory circular ferrite magnetic core bar CA and CB featuring the rectangular hysteresis characteristics of different critical magnetic fields as shown in the diagram. Magnetic core CA and CB feature the hysteresis characteristics shown by the broken lines and the solid lines respectively. The magnetization state of core CA and CB are never inverted possibly even though the magnetization force less than HC(A) may be applied to core C. With application of the magnetization force which is over HC(A) and under HC(B) to core C, the magnetization state is inverted only for core CA. And the magnetization state may possibly be inverted for core CA and CB in case the magnetization force of over HC(B). Thus, the information of 2-bit can be memorized via one unit of core C.

Title: High-voltage level conversion circuit
Inventor: SUTEIIBUN UERUZU
IPC: G11C16/22
Filed: 1992-05-07
Abstract: PURPOSE: To prevent accidental programming or erasing of a memory array by opening a switch by a level converter to stop application of an erase voltage level during power-up or power-down. CONSTITUTION: A high voltage level converter 60a turns off an erase switch 30 during power-up and power-down to secure the data integrity of the memory array. For example, 12V is applied to a gate 36 by the high voltage level converter 60a to turn off the erase switch 30. The high voltage level converter 60a outputs 12V each time when an input signal LowVcc 38 goes to the active state. The voltage level of LowVcc 38 is in the range of 4 to 10V when being in the active state. With respect to LowVcc in the active state, the output level of a logical power source Vcc is lower than a steady-state level or some desired never. The converter 60a outputs 12V independently of the digital input state to this converter 60a each time when LowVcc 38 goes to the active state.

Abstract: PURPOSE: To produce a silicon steel sheet excellent in magnetic properties and blankability by peeling a film by thermal stress generated at the time of temp. lowering in the latter stage of finish annealing. CONSTITUTION: For example, a steel stock contg., by weight, 0.01 to 0.10% C, 2 to 4.5% Si, 0.03 to 0.10% Mn or the like is subjected to hot rolling and cold rolling to finish its sheet thickness into a final one, and decarburizing annealing is executed in wet hydrogen to form an oxidized layer on the surface of the steel sheet. After that, it is applied with a separation agent for annealing having a compsn. consisting of 10 to 20% MgO, 20 to 50% Al2 O3 , and the balance SiO2 , and finish annealing is executed. Thus, a ceramic film in which the coefficient of linear expansion is regulated to <=0.5 times that of a silicon- contg. material is formed in the process of the finish annealing, and the film is peeled by thermal stress generated between the film and the stock at the time of temp. lowering after the subsequent finish annealing.  In this way, the precipitation of nitrides in the vicinity of the surface layer of ferrite can be suppressed by the film formed in the process of the finish annealing.
