Anticorrosion magneto-optical recording medium is disclosed. The magneto-optical recording medium comprises a recording layer formed of an amorphous alloy of transition metal and rare-earth metal such as Tb--Fe or Tb--FeCo. On the recording layer, there are provided a transition metal layer such as FeCoCr alloy layer and a rare-earth metal layer such as Tb, in this order. Selective oxidation of rare-earth metal in the recording layer is effectively avoided by the existance of the layers.

Information indicating whether or not a printhead of a printer has been replaced or detached is obtained. Before the start of printing on the printer, a message is displayed prompting for print position adjustment of the printer if it is determined, based on the obtained information, that the printhead has been replaced or detached. The information indicating whether or not a printhead has been replaced or detached is initialized based on a response to the displayed message.
摘要:
An oxygen-containing gas supply passage and an oxygen-containing gas discharge passage extend through a set of diagonal positions of a first metal separator, and a fuel gas supply passage and a fuel gas discharge passage extend through the other set of diagonal positions of the first metal separator. A fuel gas flow field is connected to the fuel gas supply passage through an inlet buffer at an upper position, and connected to the fuel gas discharge passage through an outlet buffer at a lower position. The inlet buffer includes a first inlet buffer area adjacent to the fuel gas supply passage and a second inlet buffer area adjacent to the fuel gas flow field. Grooves of the first inlet buffer area are deeper than grooves of the second inlet buffer area in the stacking direction.

A printing apparatus can quickly cancel a print job without any influence on the other subsequent print jobs when a print cancel instruction is issued. During printing, if a print cancel instruction is inputted from a printer operation unit, a printer function manager notifies a print command interpreter of the cancellation. The print command interpreter searches data processed at that time in a transmission/reception buffer for an end mark command indicating the end of the cancelled job. Then the print command interpreter deletes the data before the end mark command.

In a thixocasting process, the following steps are used: a step of subjecting, to a heating treatment, an Al-Si based alloy material having a hypo eutectic crystal composition and a characteristic that a first angled endothermic section appearing due to the melting of a eutectic crystal and a second angled endothermic section appearing due to the melting of a component having a melting point higher than a eutectic point exist in a differential calorimetric curve, thereby preparing a semi-molten Al-Si based alloy material having solid and liquid phases coexisting therein; a step of pouring the semi-molten Al-Si based alloy material into a cavity in a casting mold under pressure; and a step of solidifying the semi-molten Al-Si based alloy material under pressure. When the temperature of a rise-start point in the first angled endothermic section is represented by T.sub.1, and the temperature of a drop-end point the first angled endothermic sections is represented by T.sub.2, the casting temperature T for the semi-molten Al-Si based alloy material is set in a range of T.sub.1 .ltoreq.T.ltoreq.T.sub.2. Thus, the fine precipitation of a primary crystal Si phase can be realized to provide an increase in strength of an aluminum alloy cast product.
