Filed: 1996-08-05
Abstract: PROBLEM TO BE SOLVED: To obtain the subject compound having high vapor pressure on an industrial scale at a low cost by reacting a specific haloalkoxy tantalum compound with a methylated metal compound and recovering the product by vacuum distillation. SOLUTION: The objective tantalum compound is expressed by the formula II and useful e.g. as a material for forming an tantalum oxide film useful e.g. as a high-dielectric insulation film for the production of semiconductor devices such as a very large scale integrated circuit. It can be produced without generating by-product and dispensing with precise control of the amount of reactants by dissolving a haloalkoxytantalum compound expressed by the formula I (X is a halogen; R is a 2-7C alkyl) (e.g. dichlorotriethoxytantalum) in a solvent such as diethyl ether, cooling the solution to -40 deg.C, dropping a diethyl ether solution of a methylated metal compound (e.g. methyllithium) little by little to the cooled solution, stirring the mixture at -40 deg.C for 1.5hr, distilling out the solvent and subjecting the residual brown solid to vacuum distillation.

Inventor: SHIOTANI KATSUHIKO
IPC: H01F1/06
Filed: 1989-08-11
Abstract: PURPOSE:To contrive improvement in mechanical strength of compression powder mold by a method wherein, after an ingot or the coarsely crushed substance of the ingot is heated up to 600 to 1100 deg.C in a non-oxidizing atmosphere, it is pulverized into fine powder of 1 to 10mum in average diameter. CONSTITUTION:The prescribed quantity of electrolytic iron, metal Nd, metal Dy and boron is melted by high-frequency heating in vacuum, and founded using a water-cooled mold. The lump glanular substance or powder obtained by glanulating the above-mentioned ingot is heated up to 600 to 1100 deg.C in a non-oxidizing atmosphere. The lattice defect of the heated substance is sharply reduced by the above-mentioned heating, and the compression moldability can be improved. The alloy powder is liable to be oxidized in the average grain diameter of 1mum or less, and sufficient coercive force is not obtained when the average grain diameter exceeds 10mum. Therefore, the fine powder of 1 to 10mum in average grain diameter is obtained by pulverizing the material after heating. As a result, the mechanical strength of the compression powder mold can be improved.

Filed: 1991-08-19
Abstract: PURPOSE:To prevent breakdown of insulating film by adjacently arranging a side having the longest distance among the sides provided not adjacent a channel region under a gate electrode of a drain diffusing region to a contact region of a substrate. CONSTITUTION:A negative static electricity is applied to an output terminal A against a VDD terminal, a voltage difference is generated across the VDD terminal and output terminal A. As the path for absorbing such voltage difference, a current 1 flows when a P channel parasitic diode 7 is biased in the backward direction and breaks down or a current 2 flows when a sub-diode is biased in the backward direction and breaks down and an N channel parasitic diode 8 is biaced in a forward direction. A voltage difference generated by static electricity is absorbed by causing curents to flow into these two current paths. A voltage difference generated between a drain diffused region 3 of N channel transistor and a gate electrode 1 can be reduced by the electrode 1 and thereby breakdown of gate insulating film can be reduced.

Abstract: PURPOSE:To securely detect the time for replacement of an ink ribbon and prevent wasteful printing or wasting of the ink ribbon from occurring, by a system wherein the content of a character storage means saved into a nonvolatile memory when a power source is turned OFF is set into a character number storage means and displayed when the power source is turned ON. CONSTITUTION:With an ink ribbon newly set, the contents of a character number buffer 31 and a nonvolatile memory 4 are cleared, and when a printing operation is carried out, the number of characters is added to the content of the buffer 31 each time a one-line amount of data are stored into a printing buffer 32, and the content is displayed on a display device 14. When a power source is turned OFF during the printing operation, the content of the buffer 31 is saved into the memory 4. When the power source is thereafter turned ON, the content of the memory 4 is read, is stored into the buffer 31, the total number of characters printed from the start of using the ink ribbon is stored, and the content is displayed on the display device 14. Accordingly, when a user knows the number of characters capable of being printed by the ink ribbon, the can judge whether the next line can be printed by the ink ribbon. Thus, the time for replacement of the ink ribbon can be detected.
