Title: Expanding type pipe welding method
Inventor: NAKAO YOSHITO
IPC: B23K33/00
Filed: 1985-04-02
Abstract: PURPOSE:To increase joining strength and to reduce costs by expanding a pipe with a smaller diameter by press fitting of a tapered jig into an end of the pipe and welding the pipe. CONSTITUTION:Pipes 6 and 6' having a different inside diameter from each other are welded through a welding part 7. The tapered jig is inserted into an end of the smaller pipe 6 and the pipe 6 is expanded to be deformed plastically. The adopted diameter of the jig is somewhat greater than the target size with consideration for spring back of the pipe and is also greater than the maximum size determined by the manufacturing tolerance. Then the greater pipe 6' is thinning worked, is beveled, and is welded. Partial contraction of the joining part is prevented and a joining strength is increased by the above method. The piping costs are reduced because of reduced pipe weight.

Title: Exhaust emission control device for engine
Inventor: TAKAHASHI HIDEAKI
IPC: F01N3/20
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To diagnose NOx absorbing capacity by detecting an air-fuel ratio of exhaust gas passed a NOx absorption reducing type catalystic converter rhodium, and finding out a peak value of an air-fuel ratio detected at the time of rich spike treatment. SOLUTION: An air-fuel ratio sensor 15 for detecting an air-fuel ratio of exhaust gas passed a catalyst 7 is arranged in an exhaust passage 5 arranged downstream from a NOx absorption reducing type catalystic converter rhodium 7 so as to detect a peak value A/F1 of a sensor generated at the time of rich spike treatment. Namely, when NOx absorbing capacity of the catalyst 7 is inferior and the rate of NOx absorbed on the catalyst 7 is reduced, NOx is eliminated through the catalyst 7, rates of HC and CO consumed by reducing are reduced, the rates of HC and CO bypassed the catalyst 7 are increased while not reducing NOx, and the peak value A/F1 of the air-fuel ratio detected by the sensor 15 is increased more than a normal value.  Therefore, the NOx absorption capacity of the catalyst 7 is calculated and diagnosed from the peak value A/F1 of the air-fuel ratio detected at the time of rich spike treatment.

Title: Compound piezoelectric material
Inventor: SAKANO HISAO
IPC: H01L41/193
Filed: 1991-03-08
Abstract: PURPOSE:To obtain a compound piezoelectric material, which is capable of zeroing substantially various constants in some direction such as alpha31, alpha33 and alphah directions, by a method wherein the piezoelectric material consists of a combination of two kinds of piezoelectric materials, which are made to differ from each other in coercive force, and the directions of polarization of these piezoelectric materials are oriented in the opposite direction to each other. CONSTITUTION:A material, which has a large coercive force and a large anisotropy in a piezoelectric constant, such as powder 11 polarizable in a high DC electric field of 50kV/cm or higher like a titanate or the like, is used as the inorganic piezoelectric material on one side of inorganic piezoelectric materials and a material, which has a small coercive force and has a small anisotropy in the piezoelectric constant, such as powder 12 polarizable easily in a low DC electric field of 40kV/cm or lower like a barrium titanate or the like, is used as the other inorganic piezoelectric material. As the polarization directions of two kinds of these piezoelectric materials 11 and 12 are different from each other, their piezoelectric behaviors reach an opposite phase to each other and negate to each other. Accordingly, when constants in the directions alpha33 vertical to an electrode surface or the direction alpha31 parallel to the electrode surface are equal to each other, the constants zero and the direction alpha31 or the direction alpha33 of some one of constants, which are not equal to each other, becomes effective.

Title: Precombustion type air suction rocket engine
Inventor: YAMADA YOSHIO
IPC: F02K7/10
Filed: 1988-03-25
Abstract: PURPOSE:To make flame holding easy as well as to facilitate the generation of thrust in vacuum and at the time of low speed by installing a main combustion chamber which mixes high temperature combustion gas produced in a precombustion chamber with air inhaled from an air suction-compression part into combustion, generating a combustion gas, and sprays it out of a nozzle. CONSTITUTION:Fuel and an oxidizer are fed to a precombustor 5 from a combustion tank 10 and an oxidizer tank 12, while a large quantity of the fuel and a small quantity of the oxidizer are sprayed to a precombustion chamber from each of lot fuel and oxidizer injection nozzles into combustion, thereby generating fuel excess high temperature combustion gas. Then, this generated combustion gas is sprayed to a main combustion chamber 3 via an injector, and this gas is mixed with a compressed air flow inhaled out of a suction-compression part 2 and thus a main combustion takes place. With this combustion, a yet higher temperature combustion gas is generated, thus a thrust can be secured by spraying this combustion gas from a nozzle 4. Consequently, combustion reaction time of the main combustion chamber 3 is shortened, and any phenomenon such as blowout or the like is prevented from occurring without installing a flame holding mechanism, thus a stable combustion is securable.

Abstract: PURPOSE: To make possible the assigning of the measuring point of each surface of a multiple layout printed matter accurately with a simple structure by inputting coordinates of a reference point on any reference surface among a plurality of surfaces and those of a measuring point. CONSTITUTION: Coordinates of a reference point on any one reference surface of a multiple layout printed matter and those of a measuring point for evaluation are inputted and the coordinates of the reference points on the remaining surfaces are determined on the basin of coordinates of the reference point on the reference surface and an array rule of a picture pattern. For example, an angle at a left lower corner of three corners among four corners in an 4×4 array of picture pattern surfaces, namely, three surfaces A, B and C are inputted in coordinates as reference point. The point of the angle of the corner of the picture pattern can be inputted in coordinates accurately by an inspecting person to achieve a higher position accuracy. Moreover, the reference point of the reference surface D is inputted.  Thus, the reference points on other surfaces can be learned on the basis of the reference points on the plurality of surfaces and a rule of array. Thereafter, when coordinates of the measuring point (X mark) of the reference surface D are inputted, the coordinates of a relative measuring point can be obtained with respect to reference points on the surfaces A, B and C.
