Title: Electric-mechanical converting element for ink jet printer
Inventor: KOTOU HARUHIKO
IPC: B41J2/045
Filed: 1978-11-28
Abstract: PURPOSE:To provide a printing head that can be driven at a low voltage, by causing magneto striction deformation of a vibrator plate disposed in the manner facing an electromagnetic coil means through energization of the coil means, and attracting the vibrator plate by magnetic force. CONSTITUTION:When electromagnetic coil 1 is energized, magnetic field passing through iron core 2 and vibrator plate 3 is produced and the vibrator plate 3 is increased in its length by the magneto striction effect. At the same time, the vibrator plate 3 is attracted to iron core 2 and capacity of pressurizing chamber 5 is resultantly increased, so that ink 7 is introduced from an ink supply passage into the pressurizing chamber 5. When electromagnetic coil 1 is de-energized, vibrator plate 3 is moved back to its original position whereupon ink 7 is made to flow back to the ink supply passage and a portion of the ink is ejected out from nozzle 6 for use in printing. In order to eject ink 7, it is necessary to increase the characteristic frequency of vibrator plate 3 since it is required to return to its original position sufficiently speedily. This problem can be solved by using a magneto striction material in making the vibrator plate.

IPC: H05K1/14
Filed: 1984-07-18
Abstract: PURPOSE:To facilitate an exchange of defective chips and to uphold the manufacturing yield of a hybrid integrated circuit by a method wherein a defective element in the defective region of the substrate is removed, a new second substrate, whereon the same wiring pattern as that in the circumferencial region of the defective element is performed, and a new element are mounted on the defective region and the new second substrate and the substrate are electrically connected. CONSTITUTION:A defective element 2' in a defective region 4', wherein there exist the defective element 2' and a defective wiring pattern, is removed, a substrate 5, whereon the same wiring pattern as that in the defective region 4' is performed, is bonded on the region 4' and a new element 2'' is mounted. After that, an electric connection between the substrate 1 and the wiring pattern on the substrate 5 is performed using a connecting means, such as bonding wires 6. By this way, even when there exists a damage, which is not correctable, in the wiring and the bonding pad in the defective region, the whole defective region is exchanged with a new one and the hybrid integrated circuit can be easily turned into a non-defective one.

Abstract: PURPOSE:To generate many kind of diagrams easily with slight storage capacity by forming a ruled-line pattern by synthesizing predetermined basic patterns and by performing the formation of the ruled-line pattern by one-character output areas on the basis of output information on output coordinates of an output equipment. CONSTITUTION:On the basis of position coordinates from a column counter 1A in a counter part 1 and X-ruled-line information from a memory 7 stored with ruled- line information, an X-pattern discrimination part 2A discriminates a pattern to output a basic or auxiliary pattern. Similarly, position coordinate of a row counter 1B and Y-ruled-line information in the memory 7 are used to output the basic or auxiliary pattern from an Y-pattern discrimination part 2B. This output is held in the X and Y pattern buffers 4A and 4B of a pattern memory part 3. The patterns from those buffers 4A and 4B are synthesized by a pattern synthesizing part 5, whose output is sent as a ruled-line pattern for one character to a printer 6 to be printed or displayed.

Filed: 1988-06-15
Abstract: PURPOSE:To perform uniform ion implantation process by making ion beams parallel by applying a voltage of an opposite phase in synchrous with scanning signals to electrodes of an electrostatic deflection system. CONSTITUTION:An ion beam 21 which has passed a primary electrostatic deflection system 24 and with its beam range restricted with a ground mask 27 enters a secondary electrostatic deflection system 31. Scanning signal of deflection plates 29, 30 is a wave synchrous with the scanning signal of the deflection system 24 and opposite in phase. As a result, the beam is made parallel in both vertical and horizontal directions to become an ion beam 21b which passes through a 2nd ground mask 33 and is irradiated to a semiconductor wafer 35 on a platen 34. Ground electrodes 36, 37, 38 prevent disturbance of electric field at the ends of deflection plates 29, 30. Thus, the parallel beam is easily generated to perform uniform ion implantation process.
