Title: Steel wire in which delayed fracture is hard to occur
Inventor: IMAGUNBAI MASAKATA
IPC: C22C38/04
Filed: 1994-04-25
Abstract: PURPOSE:To produce a steel wire in which delayed fracture is hard to occur and having high strength by subjecting the stock with a pearlitic structure contg. specified amounts of C, Si, Mn, S, O and Ca to cold wire drawing. CONSTITUTION:The stock with a pearlitic structure contg., by weight, 0.6 to 1.2% C, <=2% Si, <=1% Mn, <=0.0025% S and <=0.0025% O, contg. Ca in a range limited by the inequality and furthermore contg., at need, one or more kinds among <=1% Cu, <=1% Cr, <=1% Ni, <=0.2% Ti, <=0.3% Nb, <=0.3% V, <=0.3% Mo and <=0.005% B is subjected to cold wire drawing. The same stock is crushed without being subjected to plastic deformation caused by the cold wire drawing to suppress the formation of harmful alumina series oxides dispersed in the steel matrix. Thus, in the stock after being subjected to the cold wire drawing, delayed fracture is hard to occur in spite of high tensile strength.

Title: Valve timing control device for internal combustion engine
Inventor: TABATA TARO
IPC: F01L1/34
Filed: 1993-04-14
Abstract: PURPOSE:To improve controllability by making the device learn the valve operating timing as the rotation phase difference of a cam shaft to a crankshaft when an engine is idling with no operating valve and calculate the actual spark advance amount when no valve is operating as an angle difference between the rotation phase difference of the cam shaft to the crankshaft and the learnt value. CONSTITUTION:Concerning a system regarding idling without valves operating as mechanically the most delayed angle, the most delayed angle position when valves are not operating is learnt at a step 110 as a phase difference of a crank angle signal and a cam angle signal and a phase angle thetai corresponding to the present opening timing is calculated. A target angle thetaT corresponding to a suitable opening timing is determined at a step 120, thetaT is compared with thetai, the angle difference is calculated if thetaT and thetai are not equal (step 140), a feedback control value is determined (step 150) and the coil of a spool valve is caused to output a signal (step 170). Thus control is accomplished with a stabled responsing speed and suitable valve opening timing covering the entire range of driving condition.

Filed: 1982-05-27
Abstract: PURPOSE:To make it possible to easily know a distance to an obstacle, by changing the intermittent number of times of a preliminarily determined transmission frequency repeated at every a definite cycle as a detecting distance becomes short. CONSTITUTION:A detecting distance relative to an alarm part 10 is imparted as signal cords ABCD and the sugnal bits of these detected data A-D are determined corresponding to the detecting distance. The output of an AND gate 21 is imparted to a buzzer drive circuit 23 which in turn sounds a piezo-electric buzzer 24 by an oscillation signal outputted from an oscillating circuit 22 in the torelant state of the AND gate 21 due to the ''H'' level output of an OR gate 20. In this case, because the intermittent number of times of the oscillation signal is changed as the detecting distance becomes short, the distance to an obstacle can be easily known from the intermittent number of times of an alarm sound.

Title: Production of silicon

IPC: C01B33/023

Abstract: PURPOSE:To prevent the amount of the consumed upper hollow electrode from increasing even if silica with a high water content is used by using a carrier gas containing a hydrocarbon gas, conveying a silica-containing raw material from a hollow hole of the upper electrode into an arc furnace and producing the silicon. CONSTITUTION:A carrier gas 5 (e.g. a mixed gas of propane gas and argon gas) containing a hydrocarbon gas is used to convey a silicacontaining raw material 4 with >=5wt.% water content is conveyed from a hollow hole provided in the upper electrode 2 into an arc furnace 1. The raw material is then heated at a high temperature with an arc 7 to reduce the silica and form silicon 8. Thereby, the hydrocarbon gas contained in the carrier gas 5 is thermally decomposed at the high temperature to produce carbon and hydrogen. In the process, since decomposition heat is absorbed, the temperature on the inner wall, etc., of the upper electrode is reduced. As a result, reaction of water contained in the silica with the electrode, reaction of silica with the electrode, etc., can be inhibited to suppress consumption of the electrode.
