    摘要: The present invention relates to the adjustment of luminance. The present invention is a method of manufacturing image forming apparatus including a step of applying characteristic shift voltage comprising a plurality of pulses in which the amplitude of the pulse obtained from the look-up table has two or more values, to the emitter, the look-up table storing the amplitude of the pulse and the number of the pulse for shifting characteristic of emitters to a predetermined luminance target value on the basis of the measurement result of the luminance. Moreover, the present invention is a method of manufacturing image forming apparatus comprising a step of applying the second pulses of characteristic shift voltage having the amplitude which was determined in response to the measurement result of the luminance after the first characteristic shift voltage had been applied to the emitter.

    摘要: Provided is an X-ray generator comprising an X-ray tube including a cylindrical body; an electron source in the body; a target at an end of the X-ray tube facing the electron source, the target generating X-rays by irradiation with electrons; a container in which the X-ray tube is arranged; insulating liquid filled between the X-ray tube and the container; and a holding member holding the body of the X-ray tube in the container, with a channel for the insulating liquid around the X-ray tube. The distance between the holding member and the end face at the end of the body in the direction in which the electron source and the target face is twice or more as large as the minimum width of the channel that is in contact with the outer surface of the X-ray tube at the end face side with respect to the holding member. This allows heat in the target to be quickly radiated, thus allowing X-rays to be generated stably for a long time.

    摘要: In an X-ray tube having an X-ray shielding member allowing an electron ray to pass through an electron passing hole toward a target, separately from the cathode-side opening of the electron passing hole, a gas exhaust path allowing communication between the inside and outside of the electron passing hole is provided so that gas molecules generated in the electron passing hole can be easily diffused out of the electron passing hole. The degradation of the cathode caused by accelerated collisions with the cathode, of cations generated by collisions of electrons with gas molecules generated in the electron passing hole by a desorption phenomenon due to electron ray irradiation to the target, is reduced.
