Title: Electrolytic plating method for molten salt
Inventor: ABE MASARU
IPC: C25D3/66
Filed: 1991-02-28
Abstract: PURPOSE:To stably perform aluminum alloy plating by an electrolytic method of molten salt regardless of admixture of moisture by using the concn. of available aluminum chloride in molten salt becoming a plating bath and performing control of this plating bath. CONSTITUTION:Aluminum alloy plating is performed on steel by an electrolytic method of molten salt by using the bath of mixed molten salt incorporating anhydrous aluminum chloride and the chloride of the other alloy component as a main component. In the plating method, control of the plating bath is performed by using the concn. of available aluminum chloride in molten salt becoming the plating bath. The concn. of available aluminum chloride is used by correcting the concn. of Al2Cl7<-> in molten salt with the concn. of total oxygen of H2O, OH<->, O<2-> and CO<32->. A rectilinear correlation is shown between the composition of the plating bath wherein this concn. of available aluminum chloride is used and a plated film. Therefore aluminum alloy plating always meeting required property is stably obtained regardless of admixture of moisture by the controlling method of the plating bath.

Abstract: PURPOSE:To eliminate vibration of an upper plate, by a method wherein an actuator, provided with a lamellar resilient member and piezoelectric elements formed on the upper and the under surface of the resilient member, is provided, and the piezoelectric element is displaced in a reverse direction to that of an output signal from a sensor electrode. CONSTITUTION:An actuator 7 is formed with a contact member 9 approximately making contact with an under surface 3a of on upper plate 3, a bimorph type piezoelectric element 10 holding the contact member 9, and a casing 11 containing and holding the piezoelectric element. The piezoelectric element 10 is horizontally held such that both end parts 12a and 12b of a resilient shim 12 ore engaged internally of a groove 11b of the casing 11. A sensor electrode 15 outputs a signal to a detecting part according to a strain produced when the piezoelectric element 10 is bent in directions X1 and X2. A voltage is applied from a control output part on an actuator electrode 16, which is displaced in a longitudinal direction. Thus, By means of an output signal from the sensor electrode 15, vibration can be directly detected through the contact member 9. This constitution enables excellent damping of vibration through further precise control of the actuator electrode 16.

Abstract: PURPOSE:To improve the yield and the quality of a semiconductor by arranging samples on the lower electrode of a reactive ion etching (RIE) unit in a point symmetry with respect to the center of the lower electrode and rotating the samples in the state for holding the relative position of the point symmetry from the start of the RIE to the end. CONSTITUTION:A plurality of samples 9 are so disposed as to be point symmetrical with respect to the rotating center on the upper surface of a lower electrode 5, and a coolant flow passage 13 is formed on the lower surface of a substrate 10. In this RIE unit, a high frequency voltage is applied by a high frequency power source to between both electrodes, gas is supplied continuously into an etching chamber 1 to etch the samples 9. However, since an etching irregularity occurs among the samples, and an etching irregularity also occurs among the portions of the samples in this state, the disposing states of the samples 9 are inverted at 180 deg. with respect to the centers of the samples in the midway of the RIE. Thus, even if the etching irregularity occurs, the irregularity is averaged over the entire etching period, and no irregular etching can be performed as a whole.

Tr of the coking coal as determined according to the Gieseler fluidity test is attained by equation I or II. In estimating the cold strength of coke to be obtd. from a certain kind of coking coal, the Gieseler fluidity test of the coking coal is conducted to determine Tm and Tr. The obtd. values of Tm and Tr are substituted for equation I or II, thereby estimating the cold strength of coke. Individual symbols in the equations I and II stand for the meanings of the formula III. According to this method, the cold strength of coke obtd. by carbonization can be simply estimated by determining the values of Tm and Tr through the Gieseler fluidity test, which enables elimination of the step of the carbonization test.

Abstract: PURPOSE:To provide the device capable of directly extruding a high-quality product from molten metal. CONSTITUTION:A passage 3 is formed by an endless groove 2 of a rotary wheel 1 provided with this endless groove 2 on its outer periphery and a stationary shoe 4 covering the endless groove 2. The molten metal 5 is continuously injected into one end of this passage 3.

The prescribed part on the side of the stationary shoe 4 constituting the passage 3 where molten metal 5 solidifies is formed of a solid material, such as graphite or silicon nitride, having self-lubricity. Then, the initially solidified layer moves on the stationary shoe 4 with the low friction resistance and, therefore, the generation of a defect in the initially solidified layer is obviated. The product having the high quality is thus extruded.
