Each of a plurality of driver ICs, which drives an associated print head, includes an analog voltage provider, which provides an analog voltage which is inversely proportional to a temperature of the driver IC, a reference temperature provider, which provides a digital value corresponding to a reference temperature, a D/A converter, which converts the digital value into a corresponding analog value, and a comparator, which compares the analog voltage with the analog value and outputs a comparison signal indicating whether the analog voltage is higher than the analog value. A temperature detector determines whether the temperature of at least one of print heads is higher than the reference temperature in accordance with the comparison signal.

A piezo-electric substrate is mainly comprised of a base material and a film formed on one main surface of the base material. In the base material, the main surface on which the film is formed is a roughed main surface. The piezo-electric substrate is obtained by forming the film comprised of a material with a coefficient of linear expansion smaller than a coefficient of linear expansion of the base material on the roughened main surface using a thermal spraying method.

In an ink jet recording apparatus, a recording head is mounted on a carriage which reciprocately moves in a widthwise direction of recording paper. A subtank is mounted on the carriage for supplying ink. A main tank stores ink which is replenished to the subtank. An ink amount detector detects an amount of ink stored in the subtank. A replenishment controller controls replenishment of ink stored in the main tank to the subtank, in accordance with the ink amount detected by the ink amount detector.

摘要:
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.
