Title: Method of exchanging liquid ample
Inventor: INOUE MUTSUHIRO
IPC: H01L21/205
Filed: 1997-11-19
Abstract: PROBLEM TO BE SOLVED: To provide a method for exchanging a liquid ample for shortening the time required for the exchange of the liquid ample. SOLUTION: In exchanging a liquid ample 12, a pressurizing step for transmitting inactive gas from a gas pipe 16 via a by-pass pipe 18 and a liquid lead- through pipe 14 to the liquid ample 12, and pushing back the remaining liquid in the liquid lead-through pipe 14 to the liquid ample 12 is carried out. As a result, the remaining liquid in the liquid lead-through pipe 14 and the by-pass pipe 18 connected with the a liquid ample 12 can be pushed back to the liquid ample 12. Then, a sucking step for sucking the liquid lead-through pipe 14 is conducted by a vacuum sucking system. Thus, the time for exchanging the liquid ample 12 can be shortened greatly as compared with a conventional case.

Title: Ink jet head
Inventor: SAKAI HIROAKI
IPC: B41J2/045
Filed: 1989-12-07
Abstract: PURPOSE:To achieve high density, multi-nozzle, and low cost of a jetting nozzle by a method wherein application of an electric field to a board having electric mechanic conversion of function is performed with ink having conductivity for a surface on a pressure chamber side and with an electrode for an opposite side surface. CONSTITUTION:A piezoelectric element board 28 with no diaphragms, having electric mechanic conversion element function is bonded directly to a substrate 1, and voltage is impressed optionally to electrodes 29-33 and conductive ink with a controller 21. When voltage is impressed to the conductive ink and the electrode 31 with the control part 21, an electric field is generated to a part put between the electrode 31 of the piezoelectric element board 28 and a pressure chamber 10, the board 28 is contracted or expanded in a face direction. Since one side surface of the piezoelectric element board 28 is restrained with the substrate 1 and the other side surface is free, a part facing the chamber 10 of the piezoelectric element board 28 is displaced to the pressure chamber side or in its opposite direction, and variation in pressure is given to the conductive ink in the chamber 10. By controlling application of voltage, a conductive ink drop can be discharged from a jetting nozzle 5.

Title: Electric discharge machine
Inventor: KARASHIMA TOSHIHARU
IPC: B23H7/26
Filed: 1989-12-07
Abstract: PURPOSE:To allow an electric discharge machine to sufficiently exhibit its abilities regardless of electrode size by disposing an electrode exchanging device main body in which plural electrodes each mounted to a clamping device are stored, and which moves and is positioned in X and Y directions relative to the clamping device and which are freely attached or removed. CONSTITUTION:To machine a large-size electrode 15 or a large-size subject 6 to be machined, a clamp screw 23 attached to a positioning clamp jig 22 is loosened. Then the sealing contact of a positioning clamp jig 21 with the positioning clamp jig 22 is released so that a little space is formed between the jigs. An electrode exchanging device main body 12 is thus drawn out in the direction of the Y-axis. As a result, the electrode exchanging device and the large-size electrode 15 or subject 6 to be machined are prevented from interfering with each other, thereby removing restriction on the size of the machinable electrode 15 or the subject 6 to be machined.
