Title: Bearing steel
Inventor: YANAGIYA TOSHIO
IPC: C22C38/60
Filed: 1987-04-13
Abstract: PURPOSE:To obtain a bearing steel hardly forming a decarburized layer during heating to high temp. and having superior rolling fatigue characteristics and wear resistance by specifying an compsn. consisting of C, Si, Mn, Cr, Pb, Bi, Sn and Fe. CONSTITUTION:This bearing steel consists of, by weight, 0.8-1.2% C, <=2.0% Si, <=2.0% Mn, 0.3-2.5% Cr, <=0.3% each of one or more among Pb, Bi and Sn and the balance Fe with impurities or further contains 0.05-1.0% Mo and has superior rolling fatigue characteristics and wear resistance. The steel hardly forms a decarburized layer during hot working or heat treatment, so the deterioration of the wear resistance due to surface decarburization can be prevented. Since the mechanical removal of a decarburized layer is made unnecessary, the cost of mechanical working can be reduced and the yield of the material can be increased.

Title: Manufacture of reduction reoxidation type semiconductor porcelain element
Inventor: NOI KEIICHI
IPC: H01G4/12
Filed: 1989-04-07
Abstract: PURPOSE:To achieve mass production by a method wherein, after reduction reoxidation type semiconductor porcelain material is molded, one surface of the molded body is buried in oxygen diffusion retarder, and binder elimination, reduction baking, and reoxidation are performed. CONSTITUTION:Reduction reoxidation type semiconductor porcelain material is used as main component, and this is molded. Binder elimination, reduction baking, and reoxidation are performed in the manner in which one surface of the molded body is buried in material (oxygen diffusion retarder) containing larger amount of material promoting to make the main component turn to semiconductor than the content of the semiconductor promoter in the main component. As a result, the formation of a highly resistive oxide layer can be restricted, so that electrodes can be directly formed in the semiconductor part, without using mechanical method, and electrostatic capacitance can be increased as compared with conventional elements. Thereby the mass production of a reduction reoxidation type semiconductor porcelain element of large capacitance is easily attained.

Title: Method and device for displaying image of sample to be scanned and sample to be used therefor
Inventor: MIZUNO FUMIO
IPC: H01J37/28
Filed: 1992-04-10
Abstract: PURPOSE:To observe non-destructively the specific structure inside of a sample by using the secondary information generated by the mutual work of the primary information, which is generated by the work of the scanning corpuscular rays and the sample irradiated by the scanning corpuscular rays, and the sample as the main signal for forming image. CONSTITUTION:As the scanning corpuscular rays, the electron beam 1b having the energy at 50 keV or more is made to enter the sample 2 deeply. At the time when the scattered electron 3b scattered by the internal structure 6 escapes from the sample 2, the scattered electron 3b and the sample 2 work to each other to generate the secondary information such as the electromagnetic wave 4b and the secondary electron 5b. In the case where the secondary electron is seen as the image signal, the secondary electron 5b is more than the secondary electron 5a as the primary information generated by the mutual work of the electron 5a and the sample 2 at the time of incidence. Consequently, with the sample image of the secondary electron signal, quantity of the scattered electron 3b reflected by the electron 5b, namely, the specific structure 6 such as the structure, defect and foreign material inside of the sample can be observed non-destructively.

Title: Oil soaking cell
Inventor: AKIYAMA HIROSHI
IPC: H01M10/32
Filed: 1993-03-23
Abstract: PURPOSE:To stabilize performance and prolong a lifetime by changing a shape of a battery jar case. CONSTITUTION:Steps are formed in a battery jar case 7, and a cross section in the upper portion of the case 7 of electrode plates 5, 6 is formed larger than that of the electrode plate. Dimensions in the width and thickness directions of the electrode plates 5, 6 can be enlarged. When an electrolyte 2 is filled in the upper portion of the electrode plates, a decrease in electrolyte by (aXc)+(bXd) is required in order that the level of the electrolyte reaches the electrode plates 5, 6. Accordingly, a quantity of the electrolyte can be decreased by (aXc)+(bXd)-bX(c+d):(a-b)Xc more than a conventional cell. Consequently, a change of the shape of the case 7 restrain lowering of the level as compared with a conventional cell even if the electrolyte 2 is reduced so that insulating oil can be prevented from adhering to the electrode plates 5, 6, to thus prolong a lifetime and stabilize performance.

Title: Multimagnetic head
Inventor: INOUE HIROTO
IPC: G11B5/29
Filed: 1990-04-04
Abstract: PURPOSE:To improve recording and reproducing by using eddy current to decrease the crosstalks based on the factor of magnetic fields and simultaneously using a grounded member to absorb displacement currents, thereby decreasing the crosstalks. CONSTITUTION:If the crosstalks based on the factor of the magnetic fields are noticed, the magnetic flux changes according to the prescribed time when the recording current flows in, for example, a coil 2b but if the grounding member 3 consisting of a conductive material is previously provided, the eddy current eventually flows in the inside and the magnetic flux created by the coil 2b is prevented from advancing into the member 3. The magnetic fluxs j1 and j2 eventually advance only to the core 1b and the magnetic paths to the cores 1 and 1c are shut off, by which the crosstalks are decreased. If the crosstalks caused by the factor of the electric field are noticed, an electric field distribution is generated in the peripheral field by the surface potential of the coil 2b but the member 3 is in the grounded state and, therefore, the displacement currents d1 and d2 are partly absorbed by the member 3 and the intensity of the magnetic field on the coil 2a, 2c surfaces is decreased.
