IPC: H05G1/34
Filed: 1980-06-27
Abstract: PURPOSE: To prevent overshooting of a tube current which occurs at the X-ray irradiation start by feedback-controlling the filament heating current and setting the integral initial value of an integrator circuit to the preliminary heating level set point.  
     CONSTITUTION: An X-ray tube 3 is driven by a DC voltage transformation generator 11 including an inverter 1. Its tube current is detected by a detector circuit 6 and applied to an integrator circuit 7. The difference between the initial value of the integrator circuit 7 and the reference voltage E 1  is integrated. A transistor Q 1  is controlled through a diode OR circuit 8 including a preliminary heating setting voltage E 2  and a filament driving inverter 10 is driven. Therefore, the initial value of the integrator circuit 7 can be to a preliminary heating level set point E 2  lower than the reference voltage E 1  through an OR circuit 8, accordingly the overshooting of tube current which occurs at irradiation start can be prevented and its value may be smoothly set to the specified target value. As a result, a good X- ray photograph can be obtained.

Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To output a stable local oscillation signal even for an instantaneous interruption of a reception signal by providing a PLL circuit that the output frequency follows at response speed slower than a fast response speed while receiving the output signal of the PLL circuit where an output frequency follows to the frequency fluctuation of a received reference signal at the fast response speed. SOLUTION: A band pass filter 14 extracts only a reference signal in an IF reception signal from a distributor 13 and sends it to a PLL circuit 15. The PLL circuit 15 makes a response at about 10 Hz of a natural frequency showing the response speed of the phase difference of an output signal. A PLL circuit 20 receives the output signal and comparatively slowly makes a response to the fluctuation of the input frequency at about 100 Hz of the natural frequency showing the response speed of the phase difference of the output signal. The output signal of the PLL circuit 20 is sent to a received frequency converter 12 as a local oscillation signal through a reception local oscillator 16. Even if the PLL circuit 15 performs a free oscillation owing to the instantaneous interruption of a reception, the PLL circuit 20 maintains a system until restoration.

When the die 1 is lowered further, a metallic foil 7 and the die 3 abut, and the foil 7 is successively drawn along the shape of a radiation part. At the point of the time when the drawing of the radiation part is completed about 80W90%, that is, at the point when the stroke of the die 3 attains 80W90% of the entire stroke of the dies, the descending of the die 1 is stopped. Here, the temps. of the dies 11 and 3 are kept at about 170W220°C by limiting the currents of the heaters 14 and 31. Thence, the die 1 is lowered to draw the radiation part at remaining 20W10%, and this completes pressing as well. In the drawing of the last 20W10%, it is cold-worked, and the Young's modulus increases considerably in accordance with work hardening.
