Title: Wire-cut electric discharge machining device
Inventor: YATOMI TAKESHI
IPC: B23H7/10
Filed: 1978-05-30
Abstract: PURPOSE:To prevent a short circuit, to increase machining speeds, and to reduce consumption of a wire electrode by controlling feeding speed of the wire electrode depending on changes of voltage and current during operation. CONSTITUTION:Machining voltage Vg between a wire electrode 1 and a work 5 is divided by a voltage divider 17. This divided voltage is added at an adder 18 to a voltage which is equivalent to short-circuited voltage level. Then output from the adder 18 is compared with a reference voltage at a comparator 19 to distinguish whether it is higher than the short-circuited voltage level. A motor controller 20 controls electric current I of a motor 10 with response to the output signal from the comparator 19. If a result is lower than the short-circuited voltage level for instance, speed of the motor 10 is increased. The reverse is applied if the result is opposite.

IPC: H01J1/24
Filed: 1986-03-25
Abstract: PURPOSE:To improve the thermal shock resistance and realize a long service life, by covering the whole periphery of a W coil at the top of the cathode composition with a porous alumina, and, removing the core wire and making a hollow form at the parts other than the top of the cathode composition. CONSTITUTION:The W coil at the top of a cathode heater is covered with Al2O3, and has no hollow parts where the Mo core is dissolved as the conventional product. The cathode heater in this composition is formed as follow: First, a W coil is wound over an Mo core wire and wound up, and then, the part shown as A' is soaked in a mixing solution of such as hydrochloric acid + nitric acid, before alumina is electrodeposited. As a result, the Mo core wire of the part responding to A' is dissolved and only the W coil remains. After that, by electrodepositing the alumina in the alumina suspension, the alumina is deposited over the whole W coil. Therefore, no gap is produced at the inner side of the W coil at the top of the heater, and the alumina membrane is formed at the inner side to prevent the embrittlement owing to the ion attack to the sleeve composition and the like of the W coil, as well as increasing the rigidity.

Inventor: SOMEYA IKUO
IPC: B41J2/255
Filed: 1985-03-29
Abstract: PURPOSE:To reduce the frequency of interruption processing, by providing printing buffer memories in two stages. CONSTITUTION:A front stage buffer 3 is formed of a shift register capable of storing 48-bit data and, by the pulse synchronous to the timing of a printing timing control part 10, printing data for even number pins and odd number pins of stored printing data are alternately transmitted to odd number line and even number line post stage buffers 4, 5 in a 12-bit unit. Odd number line and even number line printing pins 8, 9 are alternately driven by odd number line and even number line drivers 6, 7. Because the transmission of printing data to the front stage buffer 3 is performed in 4 columns and a 48-bit unit, the interruption signal of the printing timing control part 10 may be generated every when the odd number line and even number line printing pins 8, 9 are driven 4 times in total. Because the frequency of the interruption signal comes to 1/4 of the driving timing of the printing pins and allowance is generated in the processing time of the printing timing control part 10, interruption processing from other I/O is enabled.
