Title: Thermal electrostatic ink jet recording head
Inventor: FUJIMURA YOSHIHIKO
IPC: B41J2/05
Filed: 1989-12-07
Abstract: PURPOSE:To achieve stabilization of holding ink at an ink discharge part by rough working precision without impairing heat transmission effect to ink from a heating resistor by a method wherein the ink discharge mouth is formed by projecting a first substrate edge part than a second substrate edge part to be arranged, and the second substrate edge part is processed by an ink emitting treatment. CONSTITUTION:A first substrate 11 an edge part of which is projected by a specific distance from an edge part of a second substrate 12 is formed by laminating a glaze layer 11b on an alumina ceramics substrate 11a in order to secure flatness and heat accumulation property. The substrate 12 is formed from a glass substrate, and an inner surface 12a of the second substrate 12 forming an ink discharge part 2 and an edge surface 12 standing in a line with the ink discharge mouth are coated by solution in which resin fine particles are dispersed. Thereafter, it is burnt to form a 5-12 mum thickness resin film 6. Therefore, since its film thickness is sufficiently thick by being compared with a thin film treatment by plasme or the like, it is strong for mechanical abrasion of wiping or the like. Further, since the edge part of the substrate 11 is projected by the specific distance from the edge part of the substrate 12, static outflow pressure of the ink is improved.

Title: Diaphragm seal valve
Inventor: KAZAMA YOICHIRO
IPC: F16J3/02
Filed: 1990-11-21
Abstract: PURPOSE:To obtain a diaphragm seal valve having a long life even in the use for a high pressure fluid pipe, by plating several pieces of the metal thin plates of the diaphragm with the ductile metal. CONSTITUTION:Each of the metal thin plates 1, 3, and 5 of a diaphragm 180 has a same shape and a same material, and each of the metal thin plates 2 and 4 has a same shape and a same material. The metal thin plates 2 and 4 have the same both surfaces to those of the thin metal plate 1, and the whole surfaces are plated with the metal which possesses ductility, e.g. gold, silver or copper in a thickness of 0.3-0.5mum. Since the metal thin plate is plated by the ductility metal, even if the metal thin plate is used for a high pressure fluid pipe, and the diaphragm is applied with a large compression load, and the center part of the diaphragm shifts vertically, the generation of crack is suppressed, and in particular, in the case where the metal thin plate is used for the high pressure fluid pipe, the life of the diaphragm is prolonged.

Filed: 1991-11-05
Abstract: PURPOSE:To improve the rigidity of a direct-acting guide without spoiling its guide characteristic in a device for guiding a moving body such as the column and saddle of a machine tool. CONSTITUTION:A direct-acting guide 4 is formed of a rail 5 and a nut 6. Plural balls 7 to be engaged with the rail 5 are supported on the inner side face of the nut 6. Plural nuts 6 are disposed at the nut support part of a moving body 3, and a block 9 is fixed to a part of these nuts 6. The moving body 3 is provided with a piezoelectric actuator 11 in the position corresponding to this nut 6. At the time of machining, the piezoelectric actuator 11 presses the nut 6 to the support face 12 of the rail 5 through the block 9. Pre-load between the rail 5 and nut 6 is thereby increased so as to improve the rigidity of the direct-acting guide 4. Since pressing force acts upon the support face 12 of the rail 5, there is no fear of deformation being generated to the rail 5 or nut 6.
