Filed: 1984-08-24
Abstract: PURPOSE:To improve strength, wear resistance, corrosion resistance, heat resistance of a soft metal and alloy thereof easily by plating and diffusing pure Ti manufactured by an electrolytic method on the surface of a soft metal and alloy. CONSTITUTION:Pure Ti, manufactured by an electrolytic method from water- soluble Ti compounds is plated or compounded on the surface of soft metal, such as noble metal, pure metals of iron, copper, zinc, lead, tin and alloys thereof, thereafter heated at <=300 deg.C. The electrolytic Ti diffuses in the soft metal and alloy to form the diffused alloy layer easily with Ti and improve the strength, corrosion resistance and heat resistance. Plastic working after Ti diffusing treatment improves also the mechanical strength of material aging hardness and durability substantially. When melting of <=500 deg.C, the strength of a module is improved substantially.

Title: Cyclone type water discharge opening
Inventor: ISO HIROYUKI
IPC: E02B9/00
Filed: 1997-06-18
Abstract: PROBLEM TO BE SOLVED: To improve the capacity and prevent scouring, by providing a water- discharge nozzle in a cylindrical head tank in which a water pipe is eccentrically fixed through a reducer. SOLUTION: A conical reducer 43 constricted from a tank 42 to a nozzle 41 is provided between the cylindrical water-discharge nozzle 41 and the cylindrical head tank 42, and a water pipe 40 is eccentrically fixed to the tank 42 to constitute a cyclone type water-discharge opening. This cyclone type water- discharge opening is installed horizontally on a base frame 44 for instance. When using it, discharge water conducted from the pipe 40 to the tank 42 is forced to form a vortex flow in the tank 42 accelerated by the reducer 43 and discharged horizontally from the nozzle 41 as a spiral flow. A spiral screw for generating a spiral flow may be provided instead of the reducer in the water-discharge nozzle.  In this way, since the flowing speed is rapidly reduced at the initial stage of water discharge, the influence range of scouring can be reduced and the diluting effect with the peripheral water can be remarkably increased.

Abstract: PURPOSE:To detect a position of a root point accurately eliminating complicated calibration by detecting a change in ratio of impedance values within a root tube as a tip of a measuring electrode gets near the root point to decrease an equivalent impedance. CONSTITUTION:An output is applied to a measuring electrode 2 through a buffer 14. A load current is detected in the form of a voltage with a resistance 5, rectified with a waveform rectifier circuit 16 to shape a waveform thereof and then, converted to a digital data with an A/D converter 17. An arithmetic circuit 18 is so arranged to compute a ratio between a data by a measuring signal with a frequency (f) and a data by a measuring signal with the frequency 5f sequentially latching the data. The results of the computation are sent to a display section 19. Generally larger between detection values attributed to the two frequencies (f) and (5f) is the one with the higher frequency, an increas ing rate thereof is higher near the root point and hence, the ratio thereof increases as a tip 2a of the electrode 2 approaches the root point. For example, a deflection of a pointer indicates that the tip 2a of the electrode 2 reaches the root point.

Next, primary wire drawing is applied to the starting wire using three rolls and annealing is applied. Next, wire drawing using a roller die is applied succeeding wire drawing using a roller die to obtain a desired thin diameter. However, in the case of wire drawing using the hole die, wire drawing (diameter reduction) is stopped within the range wherein the density of flux does not increase. By this way, the dispersion of the variation of the sheath wall thickness per the wire length is restrained within a given value or less, whereby the breaking of the wire during wire drawing using the hole die is prevented.
