Title: Wear-resistant aluminum alloy
Inventor: KANBE YOJI
IPC: C22C21/02
Filed: 1988-05-23
Abstract: PURPOSE:To facilitate the manufacture of sliding parts by specifying respective contents of Si, Fe, Mn, P, Na, Sr and Sb in an Al alloy and also forming a coarse eutectic Si structure so as to improve wear resistance and castability. CONSTITUTION:Additive elements in a wear-resistant Al alloy are constituted so that Si, Fe, Mn, P, Na Sr and Sb contents are controlled to 9-13% by weight, <0.3%, <0.3%, <0.001%, <0.002%, <0.03% and <0.04%, respectively, and, if necessary, 0.3-0.6% Mg is added. At the time of casting this Al alloy into the prescribed parts shape, the structure of this Al alloy is formed into a coarse eutectic Si structure, e.g., by controlling the cooling rate to about 0.1-1 deg.C/sec. Since this Al alloy has superior castability, sliding parts, etc., can be easily manufactured. Further, this Al alloy has excellent wear resistance, by which the seizure load of sliding parts, etc., is increased and wear loss can be reduced.

Abstract: PURPOSE: To enable counting time in high accuracy for long time by counting pulses of high frequency produced from an oscillator at every half cycle of commercial alternating current by a timer counter and controlling an oscillator enable by n shift counter.  
     CONSTITUTION: A commercial alternating current is applied through a full-wave rectifier 2 and a waveform shaper 3 to a flip-flop FF5, which is thereupon set at every half wave of the commercial alternating current to allow a timer oscillator 6 to generate a clock pulse of higher frequency than the commercial alternating current.

Title: A/d converter
Inventor: ONO KOICHI
IPC: H03M1/36
Filed: 1994-06-08
Abstract: PURPOSE:To obtain a parallel A/D converter having a wide input range without causing a sparkle error by providing a latch circuit and a function extracting and latching the output voltage of the preamplifier of a comparator between the preamplifier and a master comparator latch. CONSTITUTION:A preamplifier 31 always amplifies a difference between an input voltage and each reference voltage and provides an amplified signal. A track hold or sample-and-hold circuit 10 samples and holds the output voltage of the preamplifier 31 at a time. An MCL(master comparator latch) 32 and an SL(slave latch) 33 confirm digital data over one period with respect to the holding voltage. An encoder detects the change point from output data of a comparator 30 and converts it into a binary code. Since the output voltage of the preamplifier 31 is held till the MCL 32 confirms data, the sparkle error caused by the dispersion in the operation of the comparator 30 is reduced.

Title: Trichloride treating method of exhaust gas containing nitrogen
Inventor: SHIMAMURA TADAO
IPC: C07C265/00
Filed: 1979-09-27
Abstract: PURPOSE: To convert nitrogen trichloride to ammonium chloride and improve the treating efficiency of exhaust gas by contacting an aqueous sulfite soln. having been controlled to the specific pH range with the exhaust gas.  
     CONSTITUTION: In treating an exhaust gas contg. nitrogen trichloride having been diluted with a large amount of air, alkali metal hydroxides such as sodium hydroxide or carbonate of alkali metals or alkaline earth metals and ammonia or the like are added to an aqueous sulfite soln. of sodium sulfite, ammonium sulfite, etc. dissolved with a small amount of lower alcohol to control its pH to a 5W10 range. When the exhaust gas is washed by spraying this soln., nitrogen trichloride is quickly converted to ammonium chloride. The reason for limiting the pH is: Above 10 pH, the exhaust gas becomes white fume and below 5 pH, sulfur dioxide is produced. Moreover, the reason for dissolving the alcohol is to suppress tha air oxidation of sulfite.

Title: Method for influencing characteristic curve of valve
Inventor: SPILLNER ROBERT
IPC: B62D123/00
Filed: 1999-05-06
Abstract: PROBLEM TO BE SOLVED: To permit inexpensive influencing on characteristic curve without diminishing the steering accuracy by detecting the actual current consumption and actual revolution of an electric motor and comparing the detected values with target revolution values at respective moments and adjusting the target revolution in the case where there is deviation between the values. SOLUTION: A characteristic curve e shows a transition of an actual characteristic curve of a steering valve of a conventional type power steering unit wherein the revolutions of a pump and a motor are constant. Positions 1, 1' show a difference between the two characteristic curves when the hydraulic pressure is relatively low. A characteristic curve d shows an earlier activation of the power steering unit as compared to the characteristic curve e, and a dead zone is smaller than that of characteristic curve e. An actual revolution and a target revolution are compared constantly up to a maximum revolution of the motor. The motor maximum revolution is a limit revolution that is adjusted according to a predetermined load of an unadjusted electric motor. Motor revolution is adjusted as a function of current consumption by comparing the two characteristic curves.
