Title: Inspecting method for long-sized tube for nuclear reactor measurement
Inventor: KASAI MAKOTO
IPC: G01N27/72
Filed: 1986-06-20
Abstract: PURPOSE:To measure the thickness of a nitride layer efficiently and nondestructively with high accuracy by inserting an eddy current detecting element into a tube and utilizing its output electric signal. CONSTITUTION:The eddy current detecting element 21 is arranged in the guide tube 15 to be measured which has the nitride layer 16 formed on its internal surface. Then when measurement is taken, the detecting element 21 is placed on the internal surface of the guide tube 15 and while the element is moved or rotated on the surface of the nitride layer 16 in contact, its electric output signal is led to a bridge circuit 24 for signal processing and the measurement is executed. In this case, an eddy current varies with the thickness of the nitride layer 16, so the electric signal obtained from the detecting element 21 is converted and calibrated by the bridge circuit 24, an amplifier, etc., thereby displaying the thickness of the nitride layer 16. Thus, the thickness of the nitride layer 16 is measured nondestructively with high accuracy throughout the overall length and overall circumference of the internal surface of the guide tube 15.

IPC: C22C45/02
Filed: 1984-07-12
Abstract: PURPOSE:To obtain excellent magnetic characteristics by a method wherein the surface configuration of the amorphous material to be used for magnetic core is limited. CONSTITUTION:It is necessary that a strip-formed wave possesses the conditions given by the below-mentioned formula when its intensity is Rf, its pitch is P(mm.) and the plate thickness of material is (t)(mm.) in order to lower the degree of effect of the stripe- formed wave and to reduce an eddy current loss. The formula is 1X10<-4(Pt<2>)/ (0.5+Rf)<1.6X10<-3>. Further, (Pt<2>)/(0.5+Rf) indicates the degree of effect of the stripe- formed wave given to an eddy current loss. Besides, if a high magnetic density is required, the relation between the degree of roughness of the surface, whereon a stripe- formed wave is generated, and the plate thickness is to be brought to 2X10<2> or below in Rl/t. At this point, Rl indicates the degree of roughness of the surface. In order to generate the above-mentioned stripe-formed wave, the melt pouring is to be performed in the temperature range of approximately 1,270-1,300 deg.C, thereby enabling to increase Rf and to decrease Rl. The optimum Rf and Rl can be selected by the melt pouring temperature as above-mentioned, and the product of low iron loss and high magnetic flux density can be accomplished.

Title: Plating device for semiconductor device
Inventor: MATSUDA MOTOAKI
IPC: H01L23/50
Filed: 1982-08-23
Abstract: PURPOSE:To improve operation efficiency, and to obtain uniform plating property by using the semiconductor device sealed with a resin as a cathode and a metal consisting of a plate as an anode, alternately stacking these device and metal and electrolyzing in a plating liquid in the device which performs electroplating the lead frame of the semiconductor device. CONSTITUTION:The semiconductor devices 2 with the lead frames 7 sealed with a resin 6 and anode plates 3 consisting of plates are stacked and set up alternately in a plating tank 1. The lead frames 7 constitute the cathodes because they are all in contact with cathode bus bars 4, the anode plates 3 constitute the anodes because they are all in contact with anode bus bars 5, and the resin 6 prevents a short circuit between the cathode and the anode as a non-conductive spacer. When the bus bars 4 and the bus bars 5 are connected to a power supply, currents flow through the lead frames 7 from the anode plates 3 and the lead frames are plated. The electrolytic currents maintain uniform current density because distances from the anode plate are equal to each other even in any section of the lead frame 7, and uniform plating property is obtained.

Title: Magnetic material
Inventor: TAMURA HIDEO
IPC: C09D5/23
Filed: 1978-11-24
Abstract: PURPOSE: To obtain an enhanced coercive force and its sharp distribution by depositing a cobalt compound and a silicic acid compound on the surface of an acicular magnetic oxide particulates.  
     CONSTITUTION: Acicular iron oxide particulates, a cobalt salt, and a silicic acid compound are dispered in an alkali solution, heat-treated, washed with water, dehydrated, and then dried. More preferably, the silicic acid compound is added into a mixture of the acicular iron oxide particulates and cobalt salt which are being dispersed into alkaline solution under heating, and then washed with water, dehydrated, and dried. This allows the cobalt salt and silicate salt to be deposited on the surface of the acicular iron oxide particulates. If the silicic acid compound is not used in the process of heating, a long period of heating causes the deposited cobalt to be partly decomposed by the alkali, resulting in a reduced coercive force. A magnetic material using such silicic acid compound provides a magnetic tape having a more enhanced coercive force with a sharper distribution than those given by a material not using such silicic acid compound.
