Abstract: PURPOSE:To make possible stable measurement of pH at a high speed by using an ion selective field effect transistor (ISFET) formed by depositing a hydrogen ion sensitive film consisting of an org. high-polymer film contg. a hydrogen ion carrier material consisting of the compd. expressed by the specific formula on the gate insulating film of a MOSFET. CONSTITUTION:The org. high-polymer film contg. the hydrogen ion carrier material consisting of the compd. expressed by the formula is used as the hydrogen ion sensitive film of the ISFET. There is, for example, a polyvinyl chloride resin as the org. high-polymer compd. and the resin from which a plasticizer is hardly elutable is preferred. The hydrogen ion sensitive film is preferably incorporated therein with an electrolyte salt, for which, for example, a hexafluorophosphate salt is used. The ISFET is a kind of a chemical semiconductor device and since the MOSFET and the ion selective electrodes are combined and integrated, the miniaturization is made possible and the ISFET has the excellent characteristics such as high input impedance and low noise intrinsic to the MOSFET. The stable measurement of pH at the high speed is thus made possible.

Title: Blowing process for converter
Inventor: NAKANISHI KIYOUJI
IPC: C21C5/32
Filed: 1982-07-01
Abstract: PURPOSE:To elevate the agitation of molten steel bath remarkably by blowing liquid oxygen into the converter from a top blowing lance in an oxygen-top blown converter. CONSTITUTION:Liquid oxygen is blown onto the surface of steel bath independently or with gaseous oxygen from the top blowing lance of a oxygen-top blown converter. This liquid oxygen jet is deeply penetrated into the steel bath and is gasified and expanded explosively, thereby agitating the molten steel bath violently. Thus, the agitation of the steel bath is increased remarkably, whereby the same agitation effect as a bottom blown converter may be achieved.

Title: Preparation of wide flange beam
Inventor: NAKANISHI TERUYUKI
IPC: B21B1/08
Filed: 1978-09-12
Abstract: PURPOSE:To elevate strength and toughness of the fillet part, by forming a convex part on the outside face or the inside face of the web part and the flange part, subsequently pressing this convex part, and finishing it to wide flange beam, in case wide flange beam is rolled and produced. CONSTITUTION:As for the angle steel with is used as a rail for the monorail, it is especially required that its fillet part has excellent strength and toughness. In this case, rolling is carried out alternately by use of the universal rolling mill which has the horizontal rolls 42 of sectional form having the concave parts 44 at the position corresponding to both inside faces of the fillet parts of rolled material, and the usual vertical rolls 16; and the universal rolling mill which has the vertical rolls 48 having the concave parts 46 at the outside of the fillet parts of rolled material, and the usual horizontal rolls 14. Rolling is carried out repeatedly so that the outside and the inside of the fillet part can have the convex parts 52 and the convex parts 50, respectively. Since the movement of both the convex parts 50, 52 in the rolling process gives a large distortion amount to the fillet parts, and the diameter of ferrite grains is minimized, toughness and strength of the fillet parts are increased.

Filed: 1994-05-26
Abstract: PURPOSE:To realize such exposure control that the photoreceptor surface potential of an exposure part is kept at a desired level without being influenced by the existence of a toner layer. CONSTITUTION:Since the part of the monitor layer 12 of a photoreceptor 10 is not provided with the coating of a photoconductive layer, it keeps potential zero.

In such a case, a light quantity transmitted through the toner layer formed on the monitor layer 12 is detected by a photosensor 20. A control means controls the light quantity based on a difference between the light quantity detected at this time and the light quantity detected previously in a state where the toner image does not exist so that the light quantity reaching the surface of the photoreceptor 10 may be the desired light quantity.
