An EPROM has a main memory cell block, test memory cell block and a redundant memory cell block in a memory cell array. The test memory cell block stores a test pattern for a device test after fabrication and a signature code including a maker code and a device code. If some memory cell group in the main memory cell block are substituted for by memory cell group in the redundant memory cell block, the corresponding bit of the signature code is generated by a signature code generator in accordance with the data for the faulty group. The signature code generator selects data read from the redundant memory cell block or the generated bit of the signature code depending on the mode of the memory device.

A digital signal processor (DSP) comprises a condition flag register directly accessible by the control microcomputer. Referring to a condition flag of the condition flag register every sampling period of the DSP, the DSP can change the content of a process every sampling period in accordance with the set status of the condition flag. The DSP sets the condition flag in the condition flag register at the beginning of a sampling period of the DSP by a set instruction, and resets the condition flag at the end of a sampling period by a reset instruction. The DSP may be modified to automatically reset the condition flag at the end of the sampling period in which the condition flag has been set.

A cast strip for an H-shape steel having excellent fire resistance and toughness for use as a structural member for constructions and a shape steel having a flange, such as an I-shape steel, produced by accelerated cooling and controlled rolling of the cast slab, are produced in an in-line manner.After the regulation of the oxygen concentration of a molten steel by a predeoxidation treatment in a steel making process to form a steel having predetermined ingredients, the steel is subjected to final deoxidation with a minor amount of Al to provide a cast slab containing, in a dispersed state, compound oxide precipitate having a capability of forming intragranular ferrite. The stead is then subjected to a treatment comprising a combination of water cooling between rolling passes with accelerated cooling after hot rolling to attain refinement of the structure and a low alloy steel, thereby improving the strength at room temperature and at high temperature and the toughness.

A linear driving device includes a hydrostatic gas bearing, a shaft supported by the bearing, and a voice-coil motor for driving the shaft in a direction of movement. The bearing and the shaft are disposed within the voice-coil motor. The device further includes a locking mechanism for constraining the movement of the shaft in its direction of movement. In addition, the voice-coil motor includes a coil assembly having a coil. The coil assembly forms a closed space surrounded by the coil. The coil assembly has a plurality of exhaust holes therein communicating with the outside from the closed space.

This application relates to an anti-inflammatory, immunosuppressive and analgesic composition, a method for its preparation, a pharmaceutical composition including it and a method of treating auto-immune diseases. The anti-inflammatory, immunosuppressive and analgesic compound is derived from ant venom extract which has been purified of contamination by a variety of non-active components present in crude ant venom extracts. A synthetic venom has also been prepared from various components. The related pharmaceutical composition has been shown to be effective in treating and alleviating the symptoms of auto-immune diseases, particularly rheumatoid arthritis.

An automatic original sheet feeder for automatically feeding an original sheet to the central portion of a platen of an image reading apparatus is disclosed, in which the orignal sheet on an original sheet tray is supplied to the platen by a feeding device. The length of the original sheet is detected by a control unit. The required distance for the original sheet to be fed is calculated depending upon the distance from a predetermined position and the central portion of the platen and the length of the original sheet. The feeding device sends the original sheet to the platen by the calculated distance, and the central portion of the original sheet is made to coincide with the central portion of the platen.
