Title: Inverter type x-ray equipment
Inventor: HATAKEYAMA KEISHIN
IPC: H05G1/20
Filed: 1986-02-26
Abstract: PURPOSE:To increase X-ray dose and improve the linearity of the relation between exposure time and dose by making the rise time characteristics of a tube voltage waveform good without the degradation of stationary characteristics in a case of stabilizing the tube voltage waveform by feedback- control. CONSTITUTION:The positive input (b) of an error amplifier 12 is an additive signal of a voltage set value Vset and an output (a) of a voltage generator 21 whose output a becomes larger than the voltage set value Vset only at the time of starting X-ray exposure. For this reason the output (d) of the error amplifier 12 increases not gradually but abruptly. The increase of the output (d) of the error amplifier 12 means the increase of supply energy to the load from a DC-DC converter. Therefore, as shown by solid line, the output (d) of the error amplifier 12 increasing abruptly right after the start of X-ray exposure, power to the load can be supplied not only by the discharge of energy charged in a smoothing capacitor 5 beforehand, but also from the DC-DC converter. Consequently, the voltage of the smoothing capacitor 5 does not happen to decrease and can be controlled to a predetermined voltage.

Filed: 1981-03-19
Abstract: PURPOSE:To reduce the side lobe by giving the specific control to the input signal phase and the phase shift degree of a phase shifter and at the same time to suppress the rise of the side lobe by carrying out the switching to an equal phase line when the beam is at the front for an electronic scanning antenna using plural phase shifters. CONSTITUTION:Phase shifters 2a-2n are connected to element antennas 1a- 1n, and phase shifter driving circuits 3a-3n which are controlled by a control circuit 5 are provided. At the same time, the signals of a transmitter 7 and a receiver 8 are applied to the shifters 2a-2n via a transmission/reception switch 6 through phase controllers 9a-9n to control the main beam direction. The input signal phase of the phase shifter 2 is controlled 9 as shown by the expressionI, and the phase shift degree is controlled 5 like the expression II. The marks of the expressionIand II are defined as the formula III. Thus the side lobe of a specified direction due to the equalized phase error can be reduced. Furthermore the controllers 9a-9n are switched to equal phase lines 12a-12n when the beam is at the front to set the phase shift degrees of the shifters 2a- 2n at an equal phase. Thus the rise of the side lobe can be suppressed.
