Abstract: Drive signal generating means generates a drive signal including a plural number of drive pulses during one period. Print data generating means generates print data to input one or a plural number of the drive pulses to each pressure generating element during one print period. The pressure generating means expands and contracts in accordance with the drive pulses input thereto, to thereby cause the ejection of an ink droplet or droplets.

Abstract: An ink jet recording apparatus is operated under a basic recording mode for recording through use of a basic unit pixel which is associated with a unit recording area corresponding to a unit print cycle, and a high-resolution recording mode for recording through use of a fine unit pixel, a plurality of fine unit pixels being arranged within the unit recording area in a main scanning direction of the recording head. The print data is developed into the jetting data such that each bit therein indicates whether the recording is conducted or not in each associated fine unit pixel, when the high-resolution recording mode is selected.

Abstract: An electric charge is supplied to or received from capacitors (C1, C2) when a piezoelectric element (C3) is charged or discharged by controlling transistors (Q17, Q18, Q15, Q10) which are in a first charging path (CL1) for charging from a power supply to the piezoelectric element (C3), a second charging path (CL2) for charging from the capacitors (C1, C2) to the piezoelectric element (C3), a first discharging path (DL1) for discharging from the piezoelectric element (C3) to ground (G) and a second discharging path (DL2) for discharging from the piezoelectric element (C3) to the capacitors (C1, C2), respectively.

Abstract: An information processing apparatus capable of printing printing information input from the outside of the apparatus using an incorporated printing device, an information processing method for such an apparatus, and a storage medium which stores control programs for such a method are provided. Also provided are an information processing apparatus which satisfies both a request to print printing information input from another information processing apparatus to an incorporated printing device and a request to print printing information formed by itself even if the two requests are simultaneously provided, an information processing method for such an apparatus, and storage medium which stores control programs for such a method.

Abstract: A concept dictionary management device includes a fundamental concept dictionary data holding portion for holding fundamental concept network connection information which represents fundamental concept network connections among words stored in a concept dictionary, a first supplemental concept dictionary data holding portion for holding first supplemental concept network connection information to be used for adding words to and deleting words from the concept network connections represented by the fundamental concept network connection information, a second supplemental concept dictionary data holding portion for holding second supplemental concept network connection information to be used only for personal use, to add one or more words to and deleting one or more words from the concept network connections obtained as a result of an addition of a deletion of the words connection by using the first supplemental concept network connection information, a concept dictionary retrieval portion for retrieving a conc

Abstract: In an information processing apparatus which operates according to an OS (operating system) stored in a ROM or an OS read from the outside, when using the OS read from the outside, an area of an address space occupied by the OS in the ROM is released so that the released area is utilized by another memory.

Abstract: A data processing apparatus for processing data structured as records, each record including a number of fields. The processing consists of replacing the contents of specific fields in specific records. The apparatus has a memory for storing a record to be processed, a memory for storing data to be used in replacement processing, a register for storing information designating specific record fields to be processed, and a control section for successively reading out the stored record fields. As each field is read out, either the field data or the replacement data are transferred as output data from the apparatus, in accordance with the corresponding information in the aforementioned register.
