摘要:
The object is to provide a method of detecting a fault which ensures high-accuracy detection of a fault in piercing-rolling. A piercing-rolling mill (10) is provided with piercer rolls (1a, 1b), a piercer plug (3), a rolling load sensor (4), a thrust load sensor (5), and a control device (6). The control device (6) measures a rolling load parameter corresponding to the rolling load of the piercer rolls (1a, 1b) and a thrust load parameter corresponding to the thrust load of the piercer plug (3), and detects a fault in piercing-rolling on the basis of a measured value of the rolling load parameter and a measure value of the thrust load parameter.

Flash memories are produced by a novel production method according to the invention, the method comprising removing field insulation films by an etching process using side walls provided adjacent to gate portions consisting essentially of a floating gate electrode, a control gate electrode, and an inter-gate insulation film, as part of a mask for the etching. The inventive method allows the production of higher integrated flash memories without causing damage, particularly degradation of dielectric strength, to the portion of a gate insulation film situated between part of the floating gate electrode and an impurity diffused source electrode formed in the substrate.

A library control system includes a library device for storing plural recording media, plural host devices for requesting for an access to the recording media, and a channel switch device for controlling connection between the host device and the library device. The library device has plural drive units and a carriage unit for carrying a recording medium. The channel switch device has a logic switch for connecting plural host devices and plural drive units in accordance with a predetermined zone map, and a zone manager for setting the zone map. Each of the host devices has a zone controller for requesting the zone manager to set a zone map each time an access request is sent from the controller. The zone manager sets a zone map so that one of the plural drive units and one of the plural host devices belong to one zone and another host device does not belong to the zone to which the one drive unit and the one host device already belong.

A library control device to controls a library device includes a designated-information acquisition section, a loading control section, a transfer control section and a medium storage control section. The transfer control section that orders, when a storage location indicated by the loading control section to a library device and a storage location designated by storage-location designating information are different from each other, the library device to transfer a storage medium from the storage location designated by the storage-location designating information to a storage location different from the storage location designated by the storage-location designating information. The medium storage control section orders, when the storage medium designated by the medium-designating information is loaded in a drive and the storage medium is transferred to a storage shelf, the library device to store the storage medium in the storage location designated by the storage-location designating information by the transfer mechanism.
摘要:
There is provided a photosensitive thermosetting resin composition of an alkali development type from which it is possible to form a coating film that is halogen-free yet has high-level flame retardancy, has a superior low warpage property after it is cured, is excellent in plasticity, resolution, soldering heat resistance, chemical resistance, and the like, and a flexible printed circuit board using the same. There is provided a photosensitive thermosetting resin composition of an alkali development type and a flexible printed circuit board using the same, the photosensitive thermosetting resin composition including: (A) a resin component having a (meth)acryloyl group and a carboxyl group in one molecule and soluble in a dilute alkali solution; (B) a phosphorus-containing epoxy thermosetting resin component; (C) a photopolymerization initiator; (D) an organophosphorus compound; and (E) a diluent, and having excellent performance in all the properties comparable to those of conventional photosensitive thermosetting resin compositions using brominated epoxy resin and a halogen-based flame retardant, and having an excellent property of not generating hydrogen bromide which has been a problem at the time of the combustion.
