Title: Timing signal shaping circuit
Inventor: KUBO KATSUSHI
IPC: H03K5/1252
Filed: 1998-07-24
Abstract: PROBLEM TO BE SOLVED: To eliminate effects due to noise which accompanies a timing signal by providing plural input buffers, which respectively output a logical signal corresponding to a timing signal and a logic circuit which processes the logical signal. SOLUTION: Input buffers 21 to 23 have 1st to 3rd threshold voltages, which are different from one another and compares the voltage value of a timing signal T to be inputted with each threshold voltage. A logical signal that is respectively outputted to H, M and L points is subjected to logical processing by a logic circuit, consisting of OR gates 26 and 28 and an AND gate 27 and is outputted as an output clock signal. When the signal T exists between the 1st threshold voltage on a high level and the 2nd threshold voltage on an intermediate level or between the 2nd threshold voltage and 3rd threshold voltage on a low level, the output of a flip-flop circuit 30 is maintained standing as logical zero. Thus, the effect of noise for making the level of the signal T into an intermediate level is eliminated.

Title: Linear klystron
Inventor: TANAKA HIROSHI
IPC: H01J23/30
Filed: 1981-12-28
Abstract: PURPOSE:To prevent effectively and appropriately the inverse coupling feedback of a linear klystron by providing an additional cavity, to which electron beams couple, between an output cavity and a collector, and providing the said additional cavity with a load which regulates the coupling. CONSTITUTION:An additional cavity 18 is provided between an output cavity 13 and a collector 9. A load 20 is connected to the cavity 18 by means of a loop 19 extending from the side wall of the cavity 18. When the inpedance of the load 20 is changed, the amplitude and the phase of a high-frequency component, which extends from a gap 21 of the cavity 18 to an input gap 6 and is developed by retrograde electrons which are inverted with an electron gun and are sent from the collector 9, are changed. Consequently, a high-frequency component caused due to the inverse coupling feedback can be almost completely offset by adjusting the load 20 so that the amplitude and the phase of a high-frequency component developed in the input gap 6 is minimized.
