Title: Device and method for machining
Inventor: SEKIYA KENICHI
IPC: H01L21/301
Filed: 1998-03-05
Abstract: PROBLEM TO BE SOLVED: To reduce a use amount of working fluid without reducing a quality by providing a gas jetting-out means for jetting-out gas so as to cause working fluid supplied from a working fluid supplying means to enter a contact part between an operation element and a workpiece. SOLUTION: The flow of grinding water 15 is strengthened by jetted-out air 14, and forcibly enters even a small gap in a contact part between a semiconductor wafer W and a grinding wheel 48. By this entered grinding water, together with the generation of vaporization heat by the vapovigation of the grinding water, the cooling of the semiconductor wafer W is further promoted. Even if the supply amount of the grinding water is only 0.4 lit./min., which is 1/5 of a conventional amount, the cooling of the semiconductor wafer is promoted by the jetting-out of air, and the surface burning of the semiconductor wafer W becomes difficult. Also, grinding distortion or cracks are difficult to occur, surface roughness is eliminated and mirror-face grinding is allowed.  Further, even if the rotational speed of a spindle 42 is reduced, thin grinding is performed so as to set the thickness of the semiconductor wafer W to, for instance 200 μm or less.

Title: Production of iron oxide for ferrite raw material from iron ore
Inventor: SAKURAI SATORU
IPC: C01G49/02
Filed: 1985-03-19
Abstract: PURPOSE:To obtain easily iron oxide for high-quality ferrite raw material, by grinding iron ore of hematite type with a small amount of impurities, and classifying the powder to remove fine powder. CONSTITUTION:Iron ore of hematite type having a composition with <=1wt% content of gangue components such as SiO2, Al2O3, MgO, CaO, etc. and a small amount of impurities is ground into 1-10mum average particle diameter. In this particle size range, the impurities such as SiO2, Al2O3, etc., are contained in the fine powder, so the powder is divided into coarse powder and fine powder which is powder having particle size larger than 0.5-5mum. The coarse powder is further ground into 1-10mum, and operation to classify by the particle diame ter of 0.5-5mum is repeated. The impurities in the iron ore can be reduced to <=about 1/2, and iron oxide for high-quality ferrite raw material is obtained.

Title: Addition of ferro-alloy or the like to molten steel
Inventor: NOGUCHI KATSUHIRO
IPC: C21C7/04
Filed: 1980-04-24
Abstract: PURPOSE: To enhance efficiency of adding additives such as ferro-alloy by a method wherein molten steel and ferro-alloy or the like in the molten state are poured into a laddle through an immersion pipe which consists of a cylindrical refractory material and is fitted to a lid of the laddle.  
     CONSTITUTION: The laddle 1 is provided with the lid 2 and the immersion pipe 3 consisting of the cylindrical refractory is fitted at a central opening 2a of the lid 2. In this case, the tip end of the pipe 3 is extended downwards closely to the bottom part of the laddle 1, with a weight 4 fitted at an upper part of the pipe 3 to prevent the latter from being floated due to the buoyancy exerted by the melt. Immediately after pouring the molten steel 6 from a converter 5 into the laddle 1 through the pipe 3, the molten ferro-alloy 7 prepared in a vessel 8 is added to the molten steel through the pipe 3. Since the ferro-alloy is added directly into the molten steel without being contacted with molten slag on the surface of the molten steel, oxidation and suspending of the ferro-alloy by the molten slag can be prevented, resulting in an extremely high yield of addition.

Therefore, the resistance of the element 1 varies without fail. Further, when the magnetic writing is performed over the entire flank, there is no problem even if the element 1 rotates or oscillates in the peripheral directions of the magnetized body 2.

Title: Constant current source circuit
Inventor: SAKUTA TAKESHI
IPC: G05F3/24
Filed: 1987-03-11
Abstract: PURPOSE:To ensure supply of a constant current regardless of the characteristic variance between working transistors Tr by using the threshold voltage of one of both Trs to eliminate the change value of the threshold voltage of the other Tr. CONSTITUTION:The Tr T1 and T2 are provided on the same chip forming an IC. When the Tr T1 is used as a constant current source Tr, the change value of a drain current ID2 of the Tr T2 caused by the variance value of the threshold voltage VTH2 of the Tr T2 is converted into voltage by a resistance RD connected to the drain of the Tr T2. This voltage is applied to the gate of the Tr T1 in an amount equivalent to the change value of the threshold voltage of the Tr T2 so that the variance value of the threshold voltage VTH1 of the Tr T1 is compensated. In this case, the resistance value of the RD is set equal to the sum of the reciprocal of the mutual conductance of the Tr T2 and a source resistance RS of the Tr T2. Thus, the change value of the threshold voltage of the Tr T2 can be detected. As a result, the gate voltage of the Tr T1 is varied to eliminate the change value of the threshold voltage of the Tr T1. Then, a constant current can be supplied.
