Title: Nonvolatile memory element, nonvolatile memory using same and driving method therefor
Inventor: NAKAO HIRONOBU
IPC: G11C14/00
Filed: 1992-05-20
Abstract: PURPOSE:To prevent a destruction of information stored in nonselective nonvolatile memory elements in writing of information, by respectively connecting bit lines to interconnecting points for each source and drain, source and drain of the nonvolatile memory elements of both ends, and side walls for each readout. CONSTITUTION:A high voltage is applied to a word line WL1, and a voltage for write is applied to a bit line BL3 connected to a drain of a MFSFET 30A in order to select a nonvolatile memory cell 31A. A voltage for write inhibit is applied to bit lines BL5, BL7 and BL9 connected to drains of MFSFETs 30B to 30D of nonselective nonvolatile memory cells 31B to 31D. A low volatge is applied to other word line WL2 and bit lines BL1, BL2, BL4, BL6 and BL8. Thus, since a ferroelectric gate film of the MFSFET 30A is polarized, data is written in the memory cell 31A but is not written in the memory cells 31B to 31D.

Title: Drill with extra-high pressure sintered body tip
Inventor: NAKASEKO SEIJI
IPC: B23B51/00
Filed: 1999-05-10
Abstract: PROBLEM TO BE SOLVED: To select a suitable grinding wheel for grinding by changing the setup angle of a front flank with an extra-high pressure sintered body tip and another central portion. SOLUTION: The tip angle of an ultra-high pressure sintered body tip 7 is set to θ1. The tip angle of a cemented carbide section on the center side than the ultra-high pressure sintered body tip 7 at a tip edge is set to θ2 more obtuse than the tip angle θ1, thereby a major cutting 3 is formed into a mid- protruded bend line shape. Since the tip angles of the ultra-high pressure sintered body tip 7 and the center section are set to different θ1, θ2, two different tool materials are not ground concurrently at the time of initial edge cutting or re-grinding for reutilization, and a grinding wheel suitable for each tool material can be selected. Clogging rarely occurs, and work efficiency is improved. Chipping caused by grinding is prevented, and a drill excellent in cutting quality can be obtained.

Title: Straddle erasing type head for flexible magnetic disk device
Inventor: SUGIMORI MASAHIRO
IPC: G11B5/265
Filed: 1987-05-27
Abstract: PURPOSE:To prevent sensitivity from being dropped at the time of reducing track width by setting up the thickness of the greater part of a part other than the vicinity of a gap in a read/write core to 1.5 times the track width or more. CONSTITUTION:A part near the gap G of the read/write core 2 is formed as a thin part 2a having thickness equal to the thickness Cw of a core material and the thickness Cw of the core material in other part is set up to 1.5 times the track width Tw. Both the end parts 3a, 3b of an erasing core 4 are arranged on both the sides of the thin part 2a of the core 2. Although the thickness of the part forming the read/write gap G must be equal to the track width as a matter of fact, it is unnecessary to set up other part to the track width, and when the thickness is set up to 1.5 times the track width, the sectional area of a magnetic path can be increased by the thickness. Even if the track width is narrow, the magnetic resistance of the read/write core 2 can be reduced and the sensitivity of the head can be improved.

Abstract: PURPOSE:To diminish scatters in ink spouting speed for stabilizing and improving the quality of printing by a method wherein a nozzle head consists of a base plate in which ink flow paths and pressure chambers are formed and a nozzle plate which is attached on the front face of the base plate and provided with nozzle holes through which ink is spouted, and the nozzle hole has a wave- shaped outline on the flow path side of the base plate. CONSTITUTION:Ink flow paths 20 and 23 and a pressure chamber 21 are formed in a base plate 33. Nozzles 10 are located on the front face of the base plate 33. The outline of a paper-side hole 10b of the nozzle 10 is circular, and a flow path-side hole 10a has a closed wavy outline which is symmetric about the center point of the paper side hole 10a. Thereby, the flow path resistance is also symmetric about the center point, and an uneven flow path resistance just before ink is spouted is diminished, causing the ink jet stream from curving. Simultaneously, the surface tension is uniform while printing is not performed, so that a stable meniscus of ink is developed and maintained in the nozzles 10. the nozzles 10 can be formed with less amount of material to be removed, and less thermal deterioration layer is generated, so that the nozzles 10 can be easily processed by laser boring process.
