Title: Manufacture of reinforced roll stock for metal-rolling mill
Inventor: KIKUHARA TAKASHI
IPC: C22C38/46
Filed: 1987-12-16
Abstract: PURPOSE:To manufacture a roll stock excellent in toughness as well as in hardness and practically causing no serious spalling by subjecting a roll-forming stock composed of a steel with a specific composition to heat treatment under specific conditions at the time of manufacturing a reinforced roll stock for metal rolling mill. CONSTITUTION:A steel stock having a composition containing, by weight, 0.3-0.8% C, 3-6% Cr, 0.4-2.0% Ni, 0.8-2.0% Mo, 0.3-1.5% V, and <2.0% W is forged, by which a reinforced roll stock for metal-rolling mill is manufactured. As to the temp-rise rate at the time of heat-treating the above stock, the temp. in the central part is regulated to the transformation point or below because, when the temp. in the central part is raised to the transformation point or above, the whole roll is hardened and a risk of loss by fracture from the inner part of the roll is brought about, and further, this stock is hardened at <=400 deg.C/hr cooling rate. By this method, the structure in the surface layer part of the roll stock is formed into martensitic state, by which the reinforced roll for rolling having >=70 hardness Hs and also superior toughness and suitable for the hot rolling and cold rolling of a steel stock can be obtained.

Title: Method for monitoring concentration of silica
Inventor: HORI TAKAHIRO
IPC: C02F1/42
Filed: 1995-12-05
Abstract: PROBLEM TO BE SOLVED: To monitor the concentration of trace silica dissolved in ultrapure water conveniently and easily by dripping water sampled from an ultrapure water production line onto a non-silicon based substrate to evaporate the water and then determining the silica. SOLUTION: Sample water is dripped onto a substrate containing sufficiently low quantity of silicon impurities, e.g. a glassy carbon wafer, and heated by means of an infrared lamp or the wafer (substrate) is mounted on a hot plate and heated and sampled water is dripped gradually thereon and evaporated. Silica element existing on the wafer surface is then determined by means of a total reflection fluorescent X-ray analyzer using tungsten Lβ rays as exciting X-rays, for example. Subsequently, concentration of silica in the sample water is determined based on a working curve determined from a standard sample. Since the concentration of dissolved trace silica can be monitored accurately, concentration of silica can be sustained stably at low level.

IPC: H01L29/06
Filed: 1989-12-08
Abstract: PURPOSE:To decrease the fluctuation of the width of a fine quantum thin wire and to suppress damages by performing inverted mesa etching with chemical etchant having anisotropy. CONSTITUTION:An InP buffer layer 2, an InGaAs quantum well layer 3 and an InP cap layer 4 are laminated on a (100) InP substrate 1 in this order. Then, a resist stripe pattern 5 is formed in the direction of <100> by an electron beam lithography method. Inverted mesa etching is performed for the cap layer 4 and the quantum well layer 3 by chemical etching. At this time, the width of a quantum thin wire is controlled with the orientation of the surface of the inverted mesa and the thickness of the cap layer 4. The thickness is not limited with the size of a resist pattern. Even if the resist pattern is fluctuated, the etching quickly progresses in the fluctuation in the direction other than a {111} surface. In this way, the fine quantum thin wire can be manufactured without machining damages, and the fluctuation in lithography can be eliminated.

Title: Excavating method and device by use of cutting bit
Inventor: KOBAYASHI KAZUMITSU
IPC: E21B10/44
Filed: 1996-11-15
Abstract: PROBLEM TO BE SOLVED: To efficiently and economically execute an excavating work in low vibration and noise without use of bentonite or the like. SOLUTION: A cutting bit 11 is at first widened by using the cutting bit 11 having an extensible function of the diameter and making the cutting radius variable to excavate the ground while advancing together with a cylindrical easing 1 (or a steel pipe pile). After excavation, the cutting bit 11 is contracted and only the cutting bit 11 is pulled up from the inside of the cylindrical easing 1 and the cylindrical easing 1 is left in the ground. Since the cutting bit excavates the ground while carrying the cylindrical casing 1, the excavated hole can be securely protected by the cylindrical easing 1, even in an uneven ground or a ground having spring water easily collapsed. And bentonite or the like is not required. And since an auger type cutting bit is used, vibration and noise levels are low in comparison with a percussion type bit.  And further, a mechanical connection like a screw connection can be used in the connection of casing pipes or the like.
