摘要:
To produce a substrate for information recording media, a substrate consisting essentially of glass for information recording media is subjected to treatment for retarding the extract of the glass component from the substrate by contacting it with a molten salt that contains at least one of hydrogensulfates and pyrosulfates, while being subjected to additional treatment for retarding the crystallization of the molten salt. In the method, preferably, the glass component to be prevented from being extracted from the substrate is a group of alkali ions, and the treatment for retarding the crystallization of the molten salt is water addition treatment of any one of treatment of supplying water to the molten salt or treatment of compensating for water being away from the molten salt.

In an internal combustion engine equipped with an adsorbent for adsorbing unburned fuel components, the amount of unburned fuel components adsorbed to the adsorbent is determined with good precision. The amount of fuel components adhered in a passage that is located upstream of the adsorbent and that conducts fuel components is determined. By taking into consideration the determined amount of adhered fuel components, the amount of fuel components adsorbed to the adsorbent is determined.

A sputtering target consisting essentially of Mn and at least one kind of R element selected from a group of Ni, Pd, Pt, Co, Rh, Ir, V, Nb, Ta, Cu, Ag, Au, Ru, Os, Cr, Mo, W, and Re. The sputtering target, at least as a part of target texture, comprises one member selected from a group of an alloy phase and a compound phase formed between the R element and Mn. In addition, oxygen content in the target is 1 weight % or less (including 0). With such a sputtering target, an anti-ferromagnetic material film consisting of RMn alloy excellent in corrosion resistivity and thermal performance can be stabilized in its film composition and film quality. By employing the anti-ferromagnetic material film, when an exchange coupling film is formed by stacking the anti-ferromagnetic material film and the ferromagnetic material film, sufficient exchange coupling force is obtained stably. Such an exchange coupling film can be used in a magneto-resistance effect element and the like.

A disc device has a movable mechanism used for moving a carriage carrying a disc so that the carriage either projects from an apparatus or is inserted into the apparatus. The disc carried by the carriage is exposed for an operator to handle the disc when the carriage projects from the apparatus. The disc carried by the carriage is contained in the apparatus after the carriage has been inserted into the apparatus. A rotating unit rotates the disc carried by the carriage and an accessing unit accesses the disc carried by the carriage. The disc device is incorporated into the apparatus. A locking mechanism locks the carriage in the apparatus, and a releasing unit causes the locking mechanism to release locking of the carriage in the apparatus. The releasing unit causes the rotating unit to stop rotating of the disc and also causes the accessing unit to stop accessing the disc, prior to each time the releasing unit causes the locking mechanism to release locking of the carriage in the apparatus. The locking mechanism is contained in the carriage.

Abbreviated dial number table and special number table are provided in external memory in control unit of digital button telephone system. For each of abbreviated dial numbers, the abbreviated dial number table stores a destination phone number prefixed with a special number concerning whether notice of a call originating party identification number should be permitted. For each of destination identification numbers, the special number table stores the special number. At call origination, it is determined whether dial data is an identification number of destination or an abbreviated dial number. If the dial data is an abbreviated dial number, reference to the abbreviated dial number table is made, dial data prefixed with the special number according to the destination is read out, and sent to the trunk line. If the dial data is an identification number of destination, reference to the special number table is made, the special number registered in the table is added to the identification number of destination, and resultant dial data is sent to the trunk line. In both the case, it becomes unnecessary to determine whether notice of the call originating phone number should be permitted according to the destination, and accordingly adding the special number as occasion demands before dialing the identification number of destination.
摘要:
A camera is designed to select at least any one of a plurality of focus areas and adjust the focus relative to an object located in the selected focus area. The camera comprises panning detection means for detecting a panning operation and focus area selecting means for selecting a specific focus area among the plurality of focus areas based on the detection result of the panning detection means.
摘要:
A color image forming system allows color image formation using a color (special color) except for yellow (Y), magenta (M), cyan (C), and black (BK) normally used in color image recording. Palette tables in which data defining use of the special colors (S1 to S4) in addition to Y, M, C, and BK are supplied from a host image data supply apparatus to a printer. At the same time, image data is transmitted in the form of data for allowing selection of the defined data in the palette tables. The printer uses Y, M, C, and BK heads and heads of the special colors S1 to S4. A control unit in the printer stores each palette table for each color (508) and outputs a driving signal to the corresponding head on the basis of the corresponding palette table.
