Title: Method and apparatus for control ac motor particularly at low speed
Inventor: HAABAATO UIRIAMU UEISU
IPC: H02P27/06
Filed: 1988-06-13
Abstract: PURPOSE: To prevent pulsation of shaft torque in low speed region by operating a converter in cycloconverter mode to generate a sinusoidal half wave current, converting it into an AC single phase power and feeding a motor with the AC single phase power. CONSTITUTION: A converter 10 is operated in cycloconverter mode to produce a sinusoidal half wave output within a desired frequency range between DC buses 16, 18. In response to a gate signal from a controller 50, four branches of an inverter 12, i.e., thyristors 34, 35, 36 and 37, function as inversion switches and the output from the inverter 12 is applied to two windings bn , cn connected in series effectively. Since an AC sine wave is generated, a motor 42 is operated as a single phase motor thus eliminating vibration and pulsation of torque.

Abstract: PURPOSE:To feed an LPG engine with fuel at an accurate and ideal characteristic, by installing an auxiliary feeding system in addition to a main feeding system for LPG fuel, while also installing a throttle valve bypass passage being regulated by a valve interlocking the gas nozzle with the throttle valve, and feedback-controlling the nozzle opening by means of an exhaust sensor. CONSTITUTION:Part of LPG out of a tank 30 is fed to a Venturi part opening 38 at the upstream of a throttle valve 43 from a secondary decompression chamber 34 of a vaporizer 32 as main fuel and the other is fed to a bypass passage 45 of the throttle valve 43 as auxiliary fuel. In this bypass passage 45, there is provided with a valve 50 interlocking the throttle valve 43, and in the upstream, there is provided with an auxiliary fuel nozzle 44 to be opened or closed with a solenoid valve 51. According to this method, in time of low opening in the throttle valve 43, the valve 50 also comes low opening, and since the nozzle 44 comes nearer to the atmosphere, differential pressure with the supplied gas pressure is small, so that even if the solenoid valve 51 performs the specified feedback by an exhaust sensor 53, a control range is narrow.

Abstract: PURPOSE:To perform the separation and purification of high-quality hyaluronic acid easily by bringing a hyaluronic acid-containing solution into contact with alumina. CONSTITUTION:The separation and purification of hyaluronic acid is performed by bringing a hyaluronic acid-containing solution into contact with alumina. Although the hyaluronic acid-containing solution applied may be one formed by the extraction of animal tissues or one produced by fermentation, the latter is desirable to produce a high-quality product inexpensively and industrially. In performing the alumina treatment of a hyaluronic acid-containing solution, it is preferable that the aqueous solution has a pH 3-10, especially, 6-9, a temperature of 0-40 deg.C and a hyaluronic acid concentration of 0.1-5g/l, especially, 0.5-2g/l. When the pH of the aqueous solution is below 3, the decomposition of hyaluronic acid occurs or the viscosity of the solution increases to make its agitation difficult, while when the pH is above 9, the effect of adsorption of impurities by alumina tends to decrease.
