Abstract: PURPOSE:To enable to perform an indenting operation or a centering operation without clearing the data once stored, by a method wherein a carriage with a printing head mounted thereon is moved directly without producing any effect on the data stored in a memory. CONSTITUTION:It is discriminated whether or not the data in question are printing data such as an alphabet, a numeral of a spae, which is inputted by operating a key, or a special space inputted by simultaneously operating a code key 66 and a space key 24. When the data in question are no printing data, a function corresponding to inputted function data is executed. In the case of printing data, when the data are not a carriage-moving command outputted by simultaneously operating the key 66 and the key 24, the inputted printing data are stored at the lowermost digit place in a display buffer memory 91, and each piece of data stored precedingly is shifted upward by one digit place. When some printing data overflows beyond the uppermost digit place as the result of the shift, the data are transferred to a printing buffer memory 93, and are printed out. Accordingly, processing for identing, centering or the like can be performed without clearing the data stored in the memory.

Abstract: PURPOSE:To provide a record head which is small in size, operated with a low voltage, and easy to manufacture, by constituting each piezoelectric actuator of electrodes and piezoelectric bodies laminated alternately, and utilizing the piezoelectric lateral displacement effect which occurs in a direction parallel to the faces of the electrodes when a voltage is charged. CONSTITUTION:A piezoelectric actuator 23, which is a laminated piezoelectric lateral displacement effect element utilizing the piezoelectric effect, has an integral constitution constituted of boardlike electric conductor layers and piezoelectric body layers laminat ed alternately and is manufactured in the shape of a comb having two grooves. When a drive circuit charges each signal electrodes 33a, 33b, 33c of the piezoelectric actuator 23 with signal voltage, the piezoelectric body layers contract due to the piezoelectric lateral displacement effect in a direction parallel to the surfaces of electrodes. At this time, ink flows in from an ink supply port, and an original length of the piezoelec tric actuator 23 is restored when the voltage is discharged. Consequently, teeth 23a, 23b, 23c previously constituting an inner wall of ink chambers 30a, 30b, 30c in an ink chamber block 24 are displaced to compress the ink chambers 30a, 30b, and 30c. As a result, pressure are generated in the ink chambers 30a, 30b, and 30c and injected through nozzles 29a, 29b, 29c communicating with each of the ink chambers for print ing.

IPC: G03F7/20
Filed: 1997-03-04
Abstract: PROBLEM TO BE SOLVED: To prevent in advance generation of defective exposure caused by the positional deviation of a mark (reticle) when a mask stage is accelerated. SOLUTION: The relative scanning of a reticle stage RST and a wafer stage WST is conducted through a stage control system 21 for the purpose of exposing a reticle pattern using a main control device. The relative positional relation between the reticle stage RST and the reticule R is detected by the detection means provided on the reticle stage RST. When the detected values of the detection device are different with each other before a mutual scanning operation performed on both stages is started and when the operation is finished, the exposing operation is discontinued. Accordingly, the generation of defective exposure, caused by the positional deviation of the reticle when the reticle stage is accelerated, can be prevented.

Abstract: PURPOSE:To obtain the optimum polishing conditions, by writing a data pattern having a proper number given from a switch group to the corresponding address within a memory and then reading the pattern by means of another switch to process it by a control program within a PROM. CONSTITUTION:Then tentative polishing conditions (polishing time, pressure) are set to a digital switch group 20, and a selection switch 22 is set at the digital mode side. Then a START key of a key switch 21 (key switch group) is pushed. Thus a microprocessor 1 reads the contents of the group 20 via an interface 10.
