Title: Pressure casting method for casting
Inventor: MURAKAMI HIDEKI
IPC: B22D27/11
Filed: 1980-09-11
Abstract: PURPOSE: To decrease internal shrinkage cavities and complete casting in a short time by packing molten metal into a metallic mold under specific pressure and pressurizing the molten metal with specific pressure.  
     CONSTITUTION: Molten metal 1 is packed into a metallic mold under ≤20kg/cm 2  pressure, and while this pressure is held maintained, high pressure of ≥300kg/cm 2  is applied to the molten metal to pressurize the same to solidify. The pressure to be exerted to a plunger 2 is divided to two stages by an oil hydraulic unit for low pressure of ≤20kg/cm 2  and an oil hydraulic unit for high pressure of ≥30kg/cm 2  and the pressure during packing and the pressure during solidifying and molding are suitably combined by a timer 20 and a pressure switch 19 to the preset pressure and time without changing the rise time of the pressure of the oil hydraulic circuits. Hence, the effect of quick packing and solidification molding is obtained.

Filed: 1979-10-02
Abstract: PURPOSE:To enable proper correction of EGR amount particularly when an engine is driven under a partial load so as to reduce the negative operation of the engine by providing a pair of EGR valves within an EGR passage whose opening timings are set differently. CONSTITUTION:In an internal combustion engine, an intake pipe 10 and an exhaust pipe 32 are communicated with each other through an EGR intake pipe 31, which enables a recirculation of a part of exhaust gas into the intake pipe 10 so as to reduce the amount of NOx contained in the exhaust gas. The intake pipe 10 is provided with an intake control valve 11 which comprises a rotary valve cooperating with an accel pedal not shown. The EGR pipe 31 is provided with the first and the second EGR rotary valve 11A and 11B arranged in series to each other whose opening timings are set differently. These two valves cooperates with the control valve 11 to open or close so that the EGR amount can be increased corresponding to an increase of the mixture amount or decreased to zero when the control valve 11 is near its fully opened position.

Title: Triangular wave generating circuit
Inventor: IMAYANADA AKIO
IPC: H03L7/113
Filed: 1979-10-02
Abstract: PURPOSE:To reduce effectively the transient during the switching of the inverter output, by securing nearly a constant lever for the output of the 1st integrator which forms the PLL. CONSTITUTION:The phase comparator 3 turns the input Pi into the reference clock signal P1 via the divider 1 for the input of one side. And the output P8 of the hysteresis generator 8 is defined as the input of the other side in correspondence to the rectangular wave output P01. Thus a comparison is given to these relative phases. The plus and the minus are delivered in case the output P8 is slower and faster than the signal P1 each. The output P3 of the comparator is integrated and stored by the integrator 4. The multiplier 5 to which the output P2 of the FV converter 2 is applied performs a multiplication between the integral output P4 and the signal P1 to produce the output P5. And the polarity of the output P5 is given inversion and noninversion by the inverter 6 and in accordance with the output P8, and then the output P6 is supplied to the integrator 7 to produce the rectangular wave having a certain inclination. The generator 8 trims the peak value of the rectangular wave. Here the voltage level of the output P4 is set irrespective of the frequency, and thus the output triangle becomes constant and steady regardless of a sudden change of the frequency.

Title: Hall element type current transformer
Inventor: SATOU TADASHI
IPC: G01R15/20
Filed: 1981-08-14
Abstract: PURPOSE:To compensate temperature at a place even when the number of Hall elements increases by inserting a resistor having the absolute value of resistance- temperature coefficient larger than the absolute value of the temperature coefficient of Hall element output voltage into a part of the feed-back resistance of  an operational amplifier. CONSTITUTION:An output of the Hall element 4 is once short-circuitted with a constant resistor 9 and then input to the input terminal of the operational amplifier 6 which calculates a sum of the outputs. A semiconductor resistor 10 of silicon semiconductor is inserted into a part of the feed-back resistance of the operational amplifier 6. A combined feed-back resistance value Rf increases in accordance with increase of ambient temperature, causing the amplification factor to increase. Therefore, drop of Hall voltage VH is compensated and a constant current transformer output VO can be obtained for change of ambient temperature. Since a positive temperature coefficient of combined feedback resistance Rf is set to an average negative temperature coefficient of sum of the Hall voltages VH short-circuitted by a resistor 9, the positive temperature coefficient of silicon semiconductor etc. must have an absolute value larger than at least the negative temperature coefficient of the Hall voltage VH.

Filed: 1995-04-27
Abstract: PURPOSE: To estimate the Al concentration in molten steel by obtaining the correlation between the Al concentration and oxygen potential in the molten steel in advance, and measuring the oxygen potential in the molten steel with an oxygen concentration battery using a solid electrolyte. CONSTITUTION: Molten steel having the Al concentration 0-65×10<-3> % is prepared, and the electromotive force of the molten steel is obtained by an oxygen concentration battery using a solid electrolyte. The correlation between the electromotive force and the Al concentration in the molten steel is obtained as a regression straight line. The electromotive force is considered as the oxygen potential, the correlation of the electromotive force against the Al concentration in the molten steel is very similar to the straight line, and the Al concentration in the molten steel can be practically easily estimated from it. The difference between the Al concentration estimated from the regression straight line and the actually measured value is about the Al concentration ±6×10<-3> % at the maximum.  The Al concentration can be accurately estimated according to this correlation.
