Title: Nonvolatile semiconductor storage device
Inventor: IKUTA NOBUO
IPC: H01L27/112
Filed: 1989-03-20
Abstract: PURPOSE:To eliminate a limitation resulting from the capacity of a memory cell, to increase breakdown strength and to improve the degree of integration by composing the memory cell arranged at the intersection of a word line and a bit line of a junction type field-effect transistor. CONSTITUTION:Memory cells disposed at the intersections of word lines 21a-21c and bit lines 22a-22c are constituted of junction type field-effect transistors 32a-32d, and data are fixed according to whether gates functioning as the word lines 21a-21c in combination are connected to an impurity diffusion layer controlling the depletion layer of a channel or not. On the read of data, cell currents are interrupted because the depletion layer is spread by the application of the reverse voltage of the gate to the cell in which the impurity diffusion layer is connected to the gate while the depletion layer is not spread in the cell, in which the impurity diffusion layer is not bonded with the gate, and cell currents are made to flow. Consequently, the presence of cell currents is detected and data are read. Accordingly, a limitation resulting from the capacity of the memory cell is eliminated, breakdown strength can be increased, and the degree of integration can be improved.

Title: Inter-block speed control method for numerical controller
Inventor: SUETOMI TAKANORI
IPC: G05D3/12
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To prevent an inter-block stop state without increasing the total machining time via a smooth speed reduction operation among a series of continuous machining operations by comparing an allowable speed with the feeding speed of a block and clamping the feeding speed of the block to the allowable speed when the former speed is higher than the latter speed. SOLUTION: The length, the feeding speed F, etc., of the next block n are confirmed in the preceding block, e.g., an n-1 section, and the mean length is calculated by a statistic technique among the blocks n-2, n-1 and n. Then, a feeding speed, i.e., the allowable speed Vn' of the block n is calculated from the mean block length to prevent an inter-block stop state that is caused when the execution of the next block n+1 is over in the block n. The feeding speed F of the block n is compared with the speed Vn', and the speed F is clamped by the speed Vn' if the former is higher than the latter. In other words, the speed F is reduced down to a speed V' to prevent the inter-block stop state of the block n.

Abstract: PURPOSE:To prevent the total discharge of a power failure prevented power unit even if power failure occurs for a long time by conducting a computer unit from the above power unit, protecting a disk device and stopping conduction from the above power unit when the power failure occurs. CONSTITUTION:When no power failure exists, the uninterruptive power unit 3 (UPS) is charged by a normal power unit. When power failure occurs, the normal power unit is interrupted due to the power failure, and the computer unit 7 is operated by the power unit by only charge of UPS 3. As soon as the conduction of a relay on the normal power unit-side is interrupted, a contact point R1 is opened and the contact point R2 of a relay on a computer unit-side is closed. A power failure signal is transmitted from UPS 3 to the computer unit 7 simultaneously with the start of power failure, and the computer unit 7 stops the writing of a disk 2, whereby the content of the disk 2 is protected. Then the computer unit 7 opens a contact point X and opens the contact point R2 and interrupts the energizing of its own computer unit. Thus, the total discharge of the power failure prevented power unit can be prevented when long power failure occurs.

Title: Manufacture of ceramic disc wheel
Inventor: MORISHITA TAKAYOSHI
IPC: F01D5/28
Filed: 1993-03-03
Abstract: PURPOSE:To improve the balance of a disc wheel as a rotational body to increase the yield in manufacturing a ceramic disc wheel by applying a cross- linked coating film to an exposed surface, thereafter applying for integration and baking it. CONSTITUTION:A kneaded ceramic powder is injection-molded into a unit block 1, the shape of which is obtained by nearly equally dividing a disc wheel along its rotation axis. The unit block 1 is formed so as to be surrounded by two hub-lines L holding a blade 2 from both sides, the rotation axis C, and both end faces S. These unit blocks 1 are combined with each other before or after degreasing, and a crosslinked coating film is applied to the exposed surfaces of the unit blocks. Hydrostatic pressure is then applied to the unit blocks to integrate them into a body and the body is baked. The hydrostatic pressure is 4t/cm<2> on higher. Thus, since the ceramic disc wheel is completed by baking a homogeneous molded body, it is excellent in balance as a rotational body. Further, no cracks occur in the molded body during degreasing, and the manufacturing yield is thereby increased.
