Title: Method and apparatus for particle dispersion metal plating
Inventor: TODA KAZUO
IPC: B24D3/00
Filed: 1986-01-10
Abstract: PURPOSE:To form a composite plating layer having a uniform particle distribution by sealing particles into a closed region formed by covering the part near the plating surface of an object to be plated and to be immersed into a plating bath with a diaphragm which prohibits the permeation of the particles and allows the permeation of the plating liquid. CONSTITUTION:A columnar body 3 of which at least the surface is formed of Ni and other conductive materials and which is formed to a circular cylindrical shape is freely rotatably installed in the plating liquid 1 in a plating cell 2. A pair of nonconductive disk bodies 6 having the diameter larger than the outside diameter of the body 3 are coaxially mounted to both side parts of the body 3 and the diaphragm 7 which prohibits the permeation of the particles and allows the permeation of the plating liquid 1 is extended on the outside peripheral face of the body 3 between the disks 6 so as to cover said face apart at a specified space therefrom. The prescribed particles 11 are sealed into the closed region 8 formed in the above-mentioned manner and while the body 3 is rotated, electricity is conducted to an anode plate 9 and the body 3 to form the composite plating layer contg. the particles 11 on the surface of the body 3. The composite plating layer having the desired particle density and dispersion state is thus obtd. with a relatively small amt. of the particles 11.

Title: Immersion nozzle for gas blowing type continuous casting
Inventor: TANADA YOSHINOBU
IPC: B22D41/58
Filed: 1980-01-16
Abstract: PURPOSE:To blow a gas uniformly over a wide range into a nozzle hole, prevent nozzle clogging and improve steel quality by providing an annular gas pressure equalizing zone in proximity to the nozzle hole of an immersion nozzle in a manner as to stride over the slag powder. CONSTITUTION:A nozzle body 11 is immersed into the molten steel 14 in a casting mold 12, and in the state that the molten steel 14' is being flowed out into a nozzle hole 15, an inert gas is supplied to the gas pressure equalizing zone 16 of the nozzle body 11. Then, the gas leakage to the outside of the nozzle body 11 is suppressed and a greater part of the inert gas may be blown into the nozzle hole 15 from the entire circumference because the gas pressure equalizing zone 16 is disposed in proximity to the nozzle hole 15. Since the gas pressure equalizing zone 16 is disposed to the nozzle body 11 by striding over the slag powder 13, and part thereof is below the slag powder 13, a sufficient gas curtain is formed between the inside wall of the nozzle hole 15 and the molten steel and the formation of deposits is prevented.

Abstract: PURPOSE: To improve an efficiency in utilizing heat contained in exhaust gas by increasing a sectional area of a passageway for the exhaust gas contacting with a portion having a high temperature and slowing down a velocity of a flow of the exhaust gas.  
     CONSTITUTION: Fuel oil sent into an oil pot 2 at a bottom of a combustion chamber 1 is evaporated and burnt by heat in the combustion chamber 1, thereby, the combustion heat is radiated through a transparent reinforced window glass 7 at a front surface of the combustion chamber 1. Exhaust gas of the combustion is induced from an exhaust port 3 above the combustion chamber 1 into a flue 5 and is descended along a backside of a back surface 4 of the combustion chamber. The back surface 4 thereof is consisting of metallic plates and a temperature thereof becomes high because flame is formed along the back surface 4, further, a complete combustion of the exhaust gas is promoted because the back surface 4 is provided with radiation plates 6 at the back side thereof. In this case, a portion with which the  flame is contacting becomes to have a highest temperature within the back surface  4, therefore, the metallic plates of the surface 4 are heated more effectively by introducing the exhaust gas to the back side thereof so as to pass therethrough as slow  as possible.

IPC: G01M3/24
Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To make it possible to standardize minute leakage detection and accurate leakage position even when the sound wave propagation characteristics of medium are irregular. SOLUTION: The sound wave propagation characteristic distribution in a monitoring area previously set by a sound wave propagation characteristic distribution calculator 12 is measured from the detection signals of a plurality of acoustic transducers 9a to 9d disposed at the periphery of the monitoring area. The signals of the transducers 9a to 9d are time and amplitude corrected by a sound source strength distribution calculator 13 by using the measured distribution. The sound source strength distribution of the area is estimated from the time and amplitude corrected detection signals. These three steps are repeated to update the characteristic distribution and strength distribution, and the presence or absence of leakage is detected by comparing the updated strength distribution and the strength distribution at the time of no leakage by a leakage detector 18.
