Title: Lamination type piezoelectric element
Inventor: KAMIYA HIDEO
IPC: H01L41/09
Filed: 1986-09-05
Abstract: PURPOSE:To obtain a piezoelectric displacement element having internal electrodes instead of using platinum by interposing specific perovskite type oxide as an intermediate layer between an internal electrode layer and a piezoelectric ceramic layer. CONSTITUTION:Lamination type piezoelectric elements are composed of piezoelectric ceramic sheets 1, internal electrode layers 2, and interconnection leads 3. The lamination type piezoelectric elements that are formed by laminating alternately the piezoelectric ceramic layers 1 and internal electrode layers 2 permit perovskite type oxide represented by an expression: (Pb1-xMx)BO3 to be interposed as the intermediate layer between the internal electrode layers 2 and the piezoelectric ceramic layers 1. The above expression: where M is a sort of elements at least among Ba, Ca as well as Sr and B is a sort of elements at least among Ti, Zr, Fe, Nb, I is shown by the following relationship:0.7 <= x <1. Thus, in the case of lamination type piezoelectric element, inexpensive conductor materials; such as palladium, palladium/silver alloy and the like can be so used as the internal electrode layers that this situation serves the purpose of reducing the cost.

Title: Writing tool using water gel ink
Inventor: TOGASHI TAIZO
IPC: C09D11/18
Filed: 1994-08-09
Abstract: PURPOSE:To make a boundary between a backflow preventing agent and a water gel ink unclear and thereby improve an outer appearance in a writing tool consisting of an ink refill in which the water gel ink is loaded with a backflow preventing agent loaded in an area after the water gel ink by dyeing the backflow preventing agent in the same color as that of the water gel ink. CONSTITUTION:This writing tool 2 is composed of the ink storage container 32, of an ink refill 3, in which a water gel ink 1 is loaded with a backflow preventing agent loaded in an area after the water gel ink 1. In this case, the backflow preventing agent 7 is dyed in the same color as that of the water gel ink 1. For example, after filling the water gel ink 1, the backflow preventing agent 7 dyed in the same color as that of the water gel ink 1 previously is loaded. As an alternative way, a mixture of the water gel ink 1 and the backflow preventing agent 7 is charged into the ink refill 3, then the water gel ink 1 is separated from the backflow preventing agent 7 centrifugally, and the backflow preventing agent 7 is dyed by adjusting it in such a manner that a colorant remains diluted.

Title: Method and device for extruding article formed of thermosetting resin
Inventor: FUKUDA YOSHIAKI
IPC: B29C48/395
Filed: 1983-11-08
Abstract: PURPOSE:To enable the successive, stable and productive extrusion of an article formed of thermosetting resin which has a substantial spiral structure and in which a spiral gap is fused up incompletely, by forming the article in the metering and smooth parts of a screw of an extruder in such a degree that it can retain its formed shape after the extrusion. CONSTITUTION:A screw has a supply part 1, a compression part 2 and a metering part 3, and the length of a smooth part 4 in the end of the screw can be selected properly from a range of 0.2D-2D (D: the diameter of the screw), or preferably 0.5D-1D. When the smooth part 4 is shorter than 0.2D, an effect of contracting the interval of a spiral is small. When the smooth part is longer than 2D, the spiral is fused up completely, and an article thus obtained is formed in a complete pipe. Accordingly, there are occasions when an incompletely-fused part of the extruded article is broken down if the article is curved lightly as occasion calls, while it normally retains a linear shape. Therefore, it can be used as a formed article having the characteristic of a spiral form, and especially the elasticity in bending.

Title: Noise reduction device
Inventor: IKEDA SHIRO
IPC: G06T5/00
Filed: 1999-07-23
Abstract: PROBLEM TO BE SOLVED: To reduce a noise reduction device capable of reducing the deterioration in phases even when an IIR filter is used for both the size reduction of a circuit and holding of a filter attenuation characteristics and obtaining high picture quality by natural noise reduction. SOLUTION: After executing noise reduction processing in a step S3, additional noise reduction is not applied to pixels of an edge part of an image (S4, S5). When the level change ΔF1 of a video signal level of a pixel to be processed after a prescribed pixel detected by a step S2 is less than a correction processing decided value TH2 as to pixels other than the pixels of the edge part, the strength of noise correction to respective pixels are increased in each pixel in a step S70 and fixed at a prescribed value L. Consequently the strength of noise correction is reduced in accordance with approach to the edge part and increased in accordance with separation from the edge part.

IPC: F26B17/10
Filed: 1989-08-12
Abstract: PURPOSE:To dry short fibers with high efficiency by dispersing and drying the sort fibers by a Coanda spiral flow produced by the introduction of a pressurized fluid. CONSTITUTION:Short fibers comprising an inorganic material and the like is dried utilizing the property of a Coanda spiral flow. More specifically, the short fibers and disposed and dried by the Coanda spiral flow produced by the introduction of the pressurized fluid Since there is formed a boundary layer in a main cylinder of a underspiral flow producing device, damage of the short fibers caused by collision of the short fibers onto a nozzle inner wall and friction of the inner wall surface are suppressed and dispersion of the short fibers is made uniform. Hereby, inorganic or other short fibers can be dried and carried with high efficiency. The present method is particularly useful for drying of short fibers of an inorganic matter, e.g., titanate and the like which are liable to be destroyed.
