Title: Wire discharge working method
Inventor: KAJITORI TOYOTADA
IPC: B23H7/06
Filed: 1995-08-23
Abstract: PROBLEM TO BE SOLVED: To provide a discharge working method capable of conducting the first stage working as well as the second stage cutting down working by one working program. SOLUTION: A program for a working path for cutting down respective male types A1-A3, cutting remaining quantity (α), and returning quantity (β) are set to be inputted. In the first stage working, only set cutting remaining quantity (α) is left to stop discharge working to memorize positions P6 (male type A1), P10 (A2), and P14 (A3). In the second stage cutting down working, automatic connection is made at a position, where only set returning quantity (β) is returned along a working groove from the working stop position of the first stage working, and the discharge working is made from this position to cut down the respective male types A. As a wire discharge working machine, a type, wherein an electric current is flowed in a wire to anneal and fuse the wire by resultant heating, is used.  Since the wire has linearity by the annealing, and a tip has a hemisherical shape by the fusing, the wire can be easily inserted into the working groove. In the second stage working, a discharge working distance is short, thereby finishing working in a short time.

Title: Droplet discharging device
Inventor: YAMAMORI SEIJI
IPC: B41J2/16
Filed: 1990-09-05
Abstract: PURPOSE:To simplify structure and permit fine droplets to be discharged by providing a piezo plate which has a specific dimension and causes a change in liquid pressure to take place in a pressure chamber due to its expansion and contraction. CONSTITUTION:Each of chambers 4 forming a part of a pressure chamber is so dimensioned as to be greater in depth than in width and greater in length than in depth. A piezo plate 5 has electrodes 7 and 8 at both side faces, a smaller thickness and width than the width and depth of the chamber 4 and a length 1/2-2 times that of the chamber 4. When an input signal 31 is applied to the electrodes 7 and 8 of the piezo plate 5 through electrodes 27 and 28 and lead wires 10 and 11, the piezo plate 5 is stretched lenghwise, pressure rises inside the pressure chamber 24 and fine droplets are discharged from an injection nozzle 25. Although the length of the piezo plate 5 is returned to its original length as the signal voltage drops and the pressure of the pressure chamber 24 is reduced, since the air suction of the injection nozzle 25 is hindered due to the surface tension retaining force of liquid meniscus, a liquid 30 is supplied from a liquid reservoir 16 through a filter 23 into the pressure chamber 24. By repeating this cyclic action, the function of a droplet injection head is performed.
