Title: Piezoelectric thin film, its production, piezoelectric element, and ink jet printer head
Inventor: SUMI KOJI
IPC: B41J2/145
Filed: 1997-04-09
Abstract: PROBLEM TO BE SOLVED: To obtain a piezoelectric thin film having a layered structure improved in piezoelectric characteristics, by laminating the second layer containing a piezoelectric substance to the first layer containing a piezoelectric substance mixed with niobium (Nb), and further to obtain a piezoelectric element, an ink jet printer head and a ferroelectric ceramic composition good in characteristics. SOLUTION: The first layer is produced by adding niobium (Nb) to lead titanate, (PbTiO3 ), lead zirconate titanate [Pb(Zr,Ti)O3 : PZT) or lead zirconate (PbZrO3 ). The second layer contains either one piezoelectric substance of lead zirconate titanate, lead lanthanum titanate, lead lanthanum zirconate titanate or lead magnesium niobate zirconate titanate. In the layer structure of a piezoelectric element, a vibration plate 3 is produced by laminating an insulating film 102 to a lower electrode film 103, and the piezoelectric element 4 is produced by laminating the second layer 200 and further an upper electrode film 104 to the first layer 100. The lower electrode film 103 is the counter electrode of the upper electrode film 104 for applying an electric voltage to the piezoelectric layer.

Title: Metal gasket
Inventor: HIRAOKA SHIN
IPC: F16J15/08
Filed: 1986-04-22
Abstract: PURPOSE:To improve durability and a sealing property by providing a stepped bead consisting of a flat part and inclined parts on both sides of said flat part surrounding a combustion chamber hole on a base plate made of an elastic metal plate, and making its spring constant larger the more removed a position is from a bolt clamping site. CONSTITUTION:A stepped bead consisting of a flat part 12a and inclined step parts 12b on both sides is provided surrounding a combustion chamber hole 6 on a metal gasket 2 which is installed in between a joining part, and its spring constant is made small as a whole. As a result, a clamping force can be made smaller to avoid damage to a joining surface by the bead while preventing the permanent set of the bead. Also, the width of the flat part of the stepped bead is formed in such a way that the spring constant in a position between bolt holes 8, 8 which is removed from the bolt clamping sites, or the bolt holes 8, 8 is larger than that near the bolt hole 8. As a result, a uniform surface pressure can be applied to the joining surface, thereby, improving durability and a sealing property.

Title: Manufacture of printed board
Inventor: TANIGUCHI YUKIHIRO
IPC: H05K3/00
Filed: 1988-04-15
Abstract: PURPOSE:To reduce the residual of a resist in a through hole after development, by applying the resist having a prescribed low viscosity after coating a board with the resist having a desired high viscosity. CONSTITUTION:A through hole 3 is made in a copper-placed laminate (board) 1 and the whole surface of the copper-placed laminate 1 including the inside wall of the through hole 3 are plated with copper. After that, a circuit 2 consisting of a copper plated layer which is patterned with a tenting technique is formed. Then, this device requires to coat both faces of the copper-placed laminated 1 where the circuit 2 is formed with high viscosity resist ink 4. In such a case, it is preferable for the viscosity of resist ink 4 having a high viscosity to have 400poise or more and it is most desirable for ink to have 500-600poise. Subsequently, resist ink 6 having a low viscosity is applied to the surface of the copper-placed laminate 1. In such a case, it is preferable for the viscosity of resist ink 4 having a low viscosity to have 300poise of less and it is most desirable for ink to have 200poise or less. As to the run of resist ink 6 having the low viscosity into the through hole 3, the inside of the through hole 3 is veiled by resist ink 6 having the high viscosity and as a result, air pressure that is in existence in the through hole 3 prevents the run of resist ink.

Title: Method for anisotropic etching of titanate
Inventor: MONTE EE DAGURASU
IPC: B01J19/12
Filed: 1993-04-19
Abstract: PURPOSE: To make it possible to eliminate the defects in material characteristics and the need for annealing restoration, and to avoid plasma contamination by immersing the surface of a titanate material into a non-alkaline liquid and illuminating the surface portion thereof with electromagnetic radiation.  
     CONSTITUTION: The substrate is immersed into hydrochloric acid (HCl) 30 of, for example, 12 mol concn. and the substrate surface is irradiated with the focused electromagnetic radiation 24 of visible/UV light which is emitted by a mercury xenon arc lamp 20 of 200 watts and propagates perpendicularly to the substrate surface 34, by which patterns are etched in the substrate 34 of lead titanatezirconate (PbTiZnO 3 ). The electromagnetic radiation 21 from a radiation source 20 is paralleled by a focusing optical system 22 and the focused electromagnetic radiation 24 is radiated to the substrate 34. A window 26 which is part of a reaction vessel 28 and is transparent to the focused electromagnetic radiation 24 permits the arrival of radiation energy at a PZT substrate 34 and an etch mask 32 defines the pattern to be etched by preventing the arrival of the radiation at a part of the substrate.

But ceramics is preferable also for the heat transfer tube 1 on the downstream side. But ceramics is preferable also for the heat transfer tube 2 on the downstream side as same as the tube 1. Between the heat transfer tubes 1 and 2, a shield 3 is provided along the heat transfer tubes 1, 2, in the crosswise direction of a flue A. As for the shield 3, the one in which rods are arranged having specified intervals among them, on arranged in the form of a grate, or a honeycomb plate can be used.

Title: Reducing method for grain size of mg alloy for casting
Inventor: HAMA YASUO
IPC: C22C1/02
Filed: 1981-06-16
Abstract: PURPOSE: To reduce almost stably the grain size of a binary Mg alloy contg. Al for casting by simple operation in a manner producing a lasting effect by melting the alloy at a specified temp. and adding a chloride flux contg. a specified amount of C to the molten alloy.  
     CONSTITUTION: A binary Mg alloy contg. Al for casting is melted at 700W 720°C, and a chloride flux contg. 5W20% C is added to the molten alloy by 0.01W0.2% of the amount of the molten alloy. When the amount of C in the flux is 10% and the amount of the added flux is 0.1%, the maximum effect is produced to reduce the grain size of the alloy. At <700°C melting temp. the flux does not produce the sufficient effect, and said temp. range is optimum. By this method the work efficiency and environment are also improved.

Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To improve volume energy density, discharge capacity and power density, and to stabilize quality by connecting current collecting tabs in the width direction of the current collecting metalic sheet surface, and forming an electrode active material layer by coating on the current collecting metallic sheet surface from above the current collecting tabs. SOLUTION: Paper strip-like current collecting tabs 2 are connected at prescribed intervals in the lengthwise direction of the current collecting metallic sheet 1 surface to a sheet electrode 3 by ultrasonic welding in the welding part 2a. An electrode active material layer 4 is formed by coating over the whole surface of a current collecting metallic sheet 1 from above these current collecting tabs 2. The joining area of the current collecting tabs 2 and the current collecting metallic sheet 1 is secured large by cutting down a noncoating edge area of the current collecting metallic sheet 1 surface, and the length of a battery can is reduced to realize high performance/compactness.  Since a noncoating area of an electrode active material is practically eliminated, deformation of the current collecting electrode sheet 1 is avoided when wound in a roll shape to eliminate damage and winding dislocation of an electrode by uniformizing tensile force.
