Abstract: PURPOSE:To provide a producing apparatus for spheroidal graphite cast iron, in which the yield of graphite spheroidizing material, etc., is improved and the entrapment of impurity into molten metal is prevented and the graphite spheroidizing material can uniformly be added. CONSTITUTION:The adding material 9 is melted and added in the molten metal on the way of passing through an adding material incorporating chamber 8 and successively, after the molten metal passes through a filter 10, the molten metal is flowed into a molten metal storing part 11 through a molten metal pouring hole 6 and once stored into the molten metal storing part 11. By passing through the filter 10 in such a way, the impurity in the molten metal adding the adding material, is removed. Further, the molten metal flowed into the molten metal storing part 3 is stored in a molten metal storing space 11 and mixed by convection naturally developed in the stored molten metal. By this method, on the way of passing through the adding material incorporating chamber 8, the concn. of the adding material added in the molten metal is uniformalized. During mixing and uniformalizing the molten metal 12, a shut-off material 14 is melted and the interval between the molten metal storing space 11 and a cavity 1 is communicated.

Title: Voltage controlled oscillator
Inventor: TOYODA NOBUYUKI
IPC: H03K3/0231
Filed: 1980-12-09
Abstract: PURPOSE:To increase the temperature dependancy of oscillated frequency, by giving a jump voltage for upper and lower side Schmitt trigger to an emitter follower circuit. CONSTITUTION:A current from a voltage controlled type current source charges up a capacitor C2. A voltage across the capacitor C2 is applied to the base of a transistor (TR) Q6 constituting a Schmitt trigger via the emitter follower of a TRQ5. On the other hand, the emitter potential of a TRQ9 is applied to the base of a TRQ7 via the emitter follower of a TRQ8. With the Q6 turned on and  the Q7 turned off, the Q9 turns on and the base potential of the Q8 is equal to the emitter potential of the Q9. Inversely, with the Q6 turned off and the Q7  turned on, the base potential of the Q8 is equal to the emitter potential of a  Q10. Thus, the upper side jump voltage of the Schmitt trigger is depending on  the emitter potential of the Q10 and the lower side jump voltage is decided with  the emitter potential of the Q9.

Filed: 1981-10-30
Abstract: PURPOSE:To perform range calibration in the desired time by an apparatus wherein a synchronous signal serving as a timing signal for starting transmission is delayed to generate a transmission pulse with a time difference and this pulse is directly coupled to a receiver. CONSTITUTION:The synchronous pulse from a synchronous signal reference timing pulse generating circuit 5 is delayed through a variable delay circuit 11, which has been adjusted in accordance with a specific delay in the transmitting/ receiving system for each radar apparatus, so as to generate transmission pulses with the delayed time difference which pulses are sent out through a modulator 3 and a transmission tube 2. A part of these signals is applied to a receiver 1 through a coupler 13 and a gate circuit 12 which are directly coupled to the receiver 1, so that an artificial video signal is formed and a distance is calculated. Then, the circuit 11 is adjusted depending on the difference between thus calculated distance and the given distance based on delay in the transmitting/ receiving systems, whereby range calibration is carried out. With such construction, it becomes possible to perform range calibration in a certain desired period during operation of the radar apparatus.

Abstract: PURPOSE:To improve the characteristics of a duplicated direct current in order to increase an inductance in the case of a small direct current in a choke coil by winding a ring wound iron core inserted with a high permeability material in a gap provided in the part of the cross section of the ring iron core. CONSTITUTION:In the case of a small duplicated direct current in a chock coil and the smaller current wherein a high permeability material 3 is not magnetically saturated, the value of an inductance is determined by the sum of the permeability of a ring wound iron core 11 inserted with the high permeability material and the permeability of a ring wound iron core 12 without a gap. If the current is increased and the high permeability material 3 is magnetically saturated, the valve of the inductance is determined by the sum of the permeability of the ring wound iron core 11 which has a gap and the permeability of the ring wound iron core 12 which has not a gap. If the duplicated direct current is increased and the ring wound iron core 12 without a gap is magnetically saturated, the value of the inductance is determined by the permeability of the ring wound iron core 11 which has the gap. In this way, the choke coil wherein the inductance is rapidly increased can be obtained if the duplicated direct current is less compared with the inductance when the duplicated direct current is greater.

Filed: 1986-07-24
Abstract: PURPOSE:To remove a servo error by storing the size of a phase error, determining a correcting variable and the direction of a residual error and automatically adjusting a phase locking position. CONSTITUTION:In an automatic residual error correcting circuit for a servo circuit, a correcting variable is determined on the basis of the contents of a phase detecting counter 120 at the input of a reference signal S (at the end of a phase detecting time) and stored in a moving variable counter 145. The direction of a residual error is transferred to a moving direction flip-flop (FF) 146, and at a time T1, the moving variable is added/subtracted by a correcting counter 147. At a time T2, the counted result (phase information) of the counter 120 is added/subtracted to/from the contents (residual error information) of the counter 147 to obtain feedback information MFD to be fed back to a speed loop. Even if the locking position is shifted due to the change of a load or the like, the shift can be turned to zero without fail and operation expanding DC gain to an infinite level can be expected at the time of sudden phase shift.
