Inventor: NISHIIKE UJIHIRO
IPC: H01F1/16
Filed: 1989-02-14
Abstract: PURPOSE:To obtain a grain oriented silicon steel sheet having a surface state excellent in adhesive properties of a coated film not to mention magnetic characteristics by performing electrolytic treatment for the grain oriented silicon steel sheet wherein secondary recrystallization annealing has been finished in an aq. soln. contg. a water-soluble halide and thereafter performing hot-melt-spray-coating on the surface of this steel sheet. CONSTITUTION:An oxidative layer on the surface of a grain oriented silicon steel sheet wherein secondary recrystallization annealing has been finished is removed by a chemical method such as pickling. Thereafter this surface is anodically electrolyzed. Thereby the steplike or groove-like recessed parts are formed in which a magnetic smooth face, namely grain boundary is >=10.4mum Rmax. Then electrolytic treatment is performed on the surface of steel sheet for which the above-mentioned electrolytic treatment has been performed in an aq. soln. contg. one or more kinds of water-soluble halides preferably at ordinary temp.-about 90<=. Then hot-melt-spray-coating is performed on the surface of steel sheet after this electrolytic treatment by oxide such as Al2O3 and ZrO2 and nitride such as Si3N4 and AlN. Thereby the grain oriented silicon steel sheet having the above-mentioned characteristics is stably obtained at low cost. Further as the water-soluble halide, e.g. HCl, NaCl HBr, NaBr, HI and KI, etc., are shown.

Title: Method for quantitative analysis of element in steel
Inventor: SENO HIDEO
IPC: G01N21/73
Filed: 1986-02-19
Abstract: PURPOSE:To accurately analyze the element in steel within a short time, by bringing a steel specimen into contact with a chlorine source under heating to convert the element in the steel specimen to chloride gas and analyzing said chloride gas. CONSTITUTION:A steel specimen is reacted with a chlorine source at high temp. As the chlorine source, chlorine gas and metal chloride etc. are used. For example, the powdery steel specimen and anhydrous cupric chloride are received in an alumina crucible 1 to be arranged in a quartz tube 2. Further, argon gas is passed through the quartz tube 2 from a bomb 3. The steel specimen and the chlorine source are heated to high temp. in an electric oven 6 to be reacted with each other and the formed chloride gas is analyzed by a plasma light emitting analyser 8. By this method, phosphorus, silicon, boron, arsenic and bismuth etc. can be properly analyzed. Because the element in steel is converted into the chloride gas, a minute amount of the element can be measured with high sensitivity and high accuracy.

Abstract: PURPOSE: To prevent a semiconductor element from being exfoliated and improve the moisture resistance of the element, by providing a heat radiator plate between a pellet and an insulating plate such that the heat radiator plate is projected beyond the edge of the insulating plate, and sealing the element on the radiator plate with a hard resin.  
     CONSTITUTION: An insulating plate 2 is soldered 3 to a heat radiator plate 1, and a heat radiator plate 9 of copper is bonded to the insulating plate 2. The plate 9 has a larger area than the plate 2 so that the former is extended beyond peripheral portions of the latter to form eaves-like sections. A semiconductor element 5 is set on the plate 9 and connects lead wires 10 which are provided separately from the plate 9. The element 5 is sealed with epoxy resin 11 on the plate 1. According to this structure, the resin 11 is restricted by the plate 9 having the eaves-like sections so that the resin 11 does not come off even when thermal strain occurs therein. Even when water runs into the structure from the interface of the plate 1 and resin 11, it never reaches the element 5. Therefore, this semiconductor device has a high moisture resistance.

Title: Controller for disk device
Inventor: SHIMIZU RIYOUSUKE
IPC: G11B21/08
Filed: 1982-03-02
Abstract: PURPOSE:To reduce the time required for accessing a track, by installing a circuit which takes out a deviation in the following location based on a location signal from a track follow-up controlling circuit and obtains the feedback voltage related to the location after amplifying the deviation, and a circuit which adds a speed damping voltage obtaining when a location signal to which a nonlinearity is given is differentiated. CONSTITUTION:The gain of a nonlinear circuit 22 which gives nonlinearities is ''1'' in the area where the position voltage is small, but, when the position voltage exceeds a value, the gain becomes >=''1''. Therefore, when a head is under follow-up control near the center of a track, the deviation in location and the speed are very small and the head receives no influence of the nonlinearity and is controlled under a condition which almost reaches the critical damping. On the other hand, when the head is accessed toward a target track and advances toward the target track, the position voltage at the time when controlling mode is switched from the access speed control to the track follow-up control is large, and, therefore, a further large position voltage is obtained by a nonlinear circuit 22 which gives nonlinearities and the gain and volume of the speed damping voltage obtained by means of a circuit 23 which differentiates the position voltage are further increased. By increasing the final speed at the time of switching of the controlling mode from the track accessing speed control to the track follow-up control, the track accessing time can be reduced.
