IPC: H01J23/027
Filed: 1990-11-07
Abstract: PURPOSE:To prevent occurrence of the degradation of characteristics due to accumulation of gas inside a collector electrode so as to stabilize the operation of a traveling-wave tube by making a hole other than a hole for passing an electron beam in a first collector electrode. CONSTITUTION:At the tip of a first collector electrode 6 of two-stage collector a hole 8 having a diameter of phid is made other than an electron beam passing hole 3 having diameter of phid0 in a position satisfying R>(1/2) R0 in consideration of the path of a leakage current and a retrograde electron. Further, the diameter of phid must be such a size as to reduce exhaust resistance and satisfying 1/2 phid0<phid<phid0 with respect to the diameter d0 of the electron beam passing hole in consideration of the path of the retrograde electron. By making the hole 8 in the position of more than one place the exhaust resistance of the hole 8 becomes smaller than that of a hole 3 and consequently the gas generated inside the collector electrode does not pass through the hole 3 but passes through the hole 8 to reach an exhaust tube 4, so that the accumulation of gas may be prevented.

Title: Ccd camera
Inventor: SAKAMAKI SUEHIKO
IPC: H04N5/341
Filed: 1989-11-22
Abstract: PURPOSE:To correct an accurate dark current for a CCD circuit while taking temperature and exposure time into account by subtracting an output voltage of the CCD camera at input of the picture element signal with an output voltage of the CCD camera at preceding optical black state to the picture element signal. CONSTITUTION:When an optical system of a CCD camera controlled by a control section 8 scans an observation object, the input of the picture element signal is in the state of optical black from a time T2 to a time T3. As a result, when a picture element signal is inputted from a CCD device 9, an analog CCD output voltage VCCD is outputted at both picture element signal input and optical black states. The control section 8 outputs a preset signal to a latch circuit 3 synchronously with the time T2 when the CCD output voltage VCCD is started for output at the optical black state. Then the reference voltage, that is, the output voltage of an operational amplifier 6 is increased/decreased by the same voltage in response to the increase/decrease in the CCD output voltage VCCD of the CCD device 9 due to a change in the dark current at the optical black state. Thus, the dark current of the CCD device is corrected accurately by taking the dispersion in the CCD device and the temperature change into account.
