    • A printer apparatus having a print head which has a first pressure chamber into which a discharge medium is introduced, a second pressure chamber into which a feed medium is introduced, and at least one set of nozzles comprised of a first nozzle communicated with the first pressure chamber and a second nozzle communicated with the second pressure chamber arranged adjacent to each other and which mixes and discharges the discharge medium and the feed medium from the nozzles, wherein a liquid repellent treatment is applied to at least one of the portion between the mutually adjoining first nozzle and second nozzle and a portion between the sets of nozzles adjoining each other on a nozzle opening face of the print head; wherein a projecting portion is formed on at least one of the portion between the mutually adjoining first nozzle and second nozzle and the portion between the sets of nozzles adjoining each other on the nozzle opening face of the print head; or wherein a recessed portion is formed between the mutually adjoining sets of nozzles of the nozzle opening face of the print head.
    • 一种具有打印头的打印机装置,所述打印头具有其中引入有放电介质的第一压力室,被引入进料介质的第二压力室,以及包括与所述第一压力连通的第一喷嘴的至少一组喷嘴 室和与第二压力室相连的第二喷嘴,彼此相邻布置,并且从喷嘴混合并排出排出介质和进料介质,其中,将液体排斥处理施加到相互邻接的部分之间的至少一个部分 第一喷嘴和第二喷嘴以及在喷墨头开口面之间彼此相邻的喷嘴组之间的部分; 其特征在于,在所述相互邻接的第一喷嘴和所述第二喷嘴之间的所述部分中的至少一个与所述打印头的喷嘴开口面上彼此相邻的所述喷嘴组之间的部分中的至少一个上形成有突出部, 或者其中在打印头的喷嘴开口面的相互邻接的喷嘴组之间形成凹部。

    • A memory management unit for an information processing system includes a controller and a non-volatile memory. The controller controls data writing process. The non-volatile memory, used for storing non-rewritable and rewritable data, is partitioned into a read-only partition to store the non-rewritable data, and a rewritable partition to store the rewritable data including apparatus-specific data including access-restricted data required for activating the information processing system. The access-restricted data is prohibited from being written during normal usage but writable at specific times. The non-rewritable data, stored in the read-only partition, is protected from an abrupt power shutdown occurring when a data writing process is conducted to the rewritable data. The controller stores the access-restricted data to the read-only partition by changing an attribute of the read-only partition of the non-volatile memory from a read-only attribute to a rewritable attribute.
    • 用于信息处理系统的存储器管理单元包括控制器和非易失性存储器。 控制器控制数据写入过程。 用于存储不可重写和可重写数据的非易失性存储器被划分为只读分区以存储不可重写数据,以及可重写分区,用于存储可重写数据,包括设备专用数据,包括访问限制 激活信息处理系统所需的数据。 访问限制的数据在正常使用期间被禁止写入,但在特定时间可写。 存储在只读分区中的不可重写数据被保护免于在对可重写数据进行数据写入处理时发生突然的电源关闭。 控制器通过将非易失性存储器的只读分区的属性从只读属性改变为可重写属性来将访问受限的数据存储到只读分区。
