摘要:
A process for producing a highly anticorrosive rare earth permanent magnet, characterized by sequentially subjecting an R—Fe—B sintered magnet to surface finishing involving cutting and/or polishing, plating pretreatment, nickel electroplating to a given plating thickness, immersion in an aqueous solution containing a phosphoric salt, washing with water and heat treatment at 150° to 400° C. for 1 to 24 hr in an atmosphere of 1.3×103 Pa or higher oxygen partial pressure so as to form a thin nickel oxide layer at the surface layer portion.

Disclosed is an integrated circuit chip having an improved ESD protection structure. The integrated circuit chip includes a core logic region having a plurality of transistor devices that are interconnected to form a specific integrated circuit device. A plurality of input/output cells are defined along a periphery of the integrated circuit chip. An ESD bus die edge seal that defines a single ring around the periphery of the integrated circuit chip is provided. The ESD bus die edge seal is positioned outside of the plurality of input/output cells closest to a physical outer edge of the integrated circuit chip. Further, a plurality of (Vss) supply cells are contained in selected ones of the plurality of input/output cells. And, a plurality of ESD cross-coupled diodes are connected between the plurality of (Vss) supply cells and the ESD bus die edge seal. Advantageously, this combined ESD bus and die edge seal provides a more compact structure that also has more uniform charged contaminant collection characteristics.

A tag detecting system for detecting a movement of a person or an object that mounts an RFID tag, a moving object detecting method, and an entrance/exit management system using the moving object detecting system are provided. The tag detecting system detects a specific person or object by restricting a detection area of the RFID tag to a narrow area. Since the moving object detecting method detects a piggyback, the entrance/exit system prevents the piggyback even if there are a number of persons passing through an entrance/exit gate almost at the same time.

In an optical disk high-speed replaying/recording apparatus, a first read data quality determining section determines a quality of read second units of digital data. Upon determination that the quality of the second units of digital data is low, a first re-reading section re-reads the first units of digital data tracks, sectors, or data blocks in the second units at a third replay speed obtained by subtracting a first predetermined speed from a second replay speed. With this, the optical disk can be replayed at a speed higher than the normal replay speed, and reproduced data can be recorded on a writable optical disk except defective data caused by reproduction defects.

The present invention provides a high/low frequency dual wireless location detection and information transmission system which is high in reliability and maintainability, and can be easily installed.A leakage coaxial inner conductor and a conductor line provided in parallel are short-circuited at an end, a single leakage coaxial operation and a loop operation of the inner conductor and the conductor line are performed at the same time, the ID of a tag is communicated using magnetic fields which locally exist near the conductor line by the loop, and wireless position detection and information communications which are less affected by the influence of ambient environments due to electromagnetic waves in a closed area are realized by open-type lines.

摘要:
A top end stop is provided to adjoin a fastener element row, and a projecting portion is formed on an inner side face of a main body such that the projecting portion projects sideway, so as to form a concave portion in which a flange of a slider invades. A projecting piece thinner than the projecting portion is located in the concave portion such that the projecting piece extends from a contact face of the projecting portion to the inner side face of the main body in a triangular shape while its front end is inclined. Consequently, the flange presses the top end stop against a tape face by sliding of the slider, the top end stop itself is reinforced, the longitudinal pulling strength is improved, and a step between the main body and the projecting portion is smoothed, whereby a top end stop favorably tactile to the skin is produced.
