An alloy ingot for permanent magnet consists essentially of rare earth metal and iron and optionally boron. The two-component alloy ingot contains 90 vol % or more of crystals having a crystal grain size along a short axis of 0.1 to 100 .mu.m and that along a long axis of 0.1 to 100 .mu.m. The three-component alloy ingot contains 90 vol % or more of crystals having a crystal grain size along a short axis of 0.1 to 50 .mu.m and that along a long axis of 0.1 to 100 .mu.m. The alloy ingot is produced by solidifying the molten alloy uniformly at a cooling rate of 10.degree. to 1000.degree. C./sec. at a sub-cooling degree of 10.degree. to 500.degree. C. A permanent magnet and anisotropic powders are produced from the alloy ingot.

A system for deleting picture information is provided for a picture information file. The system has a keyboard, a 2-dimension scanning device, a magnetic tape device, a display device and a control device including a microprocessor. The deletion of the picture information recorded in the magnetic tape device is performed by recording the delete mark in a delete mark recording area of the retrieval title corresponding to the picture information to be deleted.
摘要:
A recording system is provided for a picture information file device having a keyboard, a 2-dimension scanning device, a magnetic tape device, a display device, and a microprocessor. When registering new picture information, a retrieval title to which a delete mark is attached is searched. The length of the picture information recorded at the position represented by this retrieval title is compared with the length of the new picture information to be recorded. If the new picture information to be recorded is shorter, the new picture information is recorded in the deleted picture information area. If the new picture information is longer, another retrieval title with a delete mark attached thereto is searched and the same comparison is made. If all the retrieval titles are searched and there is not retrieval title with a delete mark, or if the new picture information is longer than the deleted picture information of the respective retriveal titles with the delete mark, the new picture information is recorded in the picture information recording area next to the area which records the final picture information.

A central processing unit determines the size of a copying sheet to be used from a document size code read out from an index information recording track of a magnetic tape by a video tape recorder of a document information filing system, and produces copying sheet size data. A copying sheet selecting device is driven according to the copying sheet size data to supply a copying sheet of the size corresponding to the copying sheet size data to a copying device. The copying device reproduces document information corresponding to the index information on the selected copying sheet supplied to it.
摘要:
A silicon single crystal wafer is subjected to two-stage heat treatment. In the first-stage it is heated at a temperature within the range of between 500.degree. C. and 1,000.degree. C. Subsequently the thus heated wafer is heated at a temperature higher than that at the first stage. Thus, a nondefective zone is formed in the surface region of the wafer, and the interior zone of the wafer becomes rich in micro defects capable of gettering impurities such as heavy metals.

According to one embodiment, a memory device includes a selection element layer, a nanomaterial aggregate layer, and a fine particle. The nanomaterial aggregate layer is stacked on the selection element layer. The nanomaterial aggregate layer has a plurality of micro conductive bodies aggregated with an interposed gap. The fine particle has at least a surface made of silicon oxynitride. The fine particle is dispersed between the micro conductive bodies in one portion of the nanomaterial aggregate layer piercing the nanomaterial aggregate layer in a thickness direction.

According to one embodiment, a nonvolatile semiconductor memory device includes a first interconnect, a second interconnect and a resistance change layer. The first interconnect extends in a first direction on a major surface of a substrate. The second interconnect extends in a second direction non-parallel to the first direction. The resistance change layer includes a conductive nanomaterial, the resistance change layer located between the first interconnect and the second interconnect and being capable of reversibly changing between a first resistance state and a second resistance state by a voltage applied or a current supplied through the first interconnect and the second interconnect. The resistance change layer has a density varied along a third direction generally perpendicular to the first direction and the second direction.
