A necessary number of initial stage element circuits, intermediate stage element circuits, and final stage element circuits are connected in cascade and combined in parallel arrangement simultaneously. The partial sum output data on the element circuits is synchronized with the inner partial sum data. In this way, it is possible to configure a high-speed high-order and high-precision FIR filter, i.e., a large-scale digital filter. Thus, it is possible to manufacture a high-order and high-precision FIR filter capable of high-speed operation of 2 GHz or above at a low cost.

A conductive coating layer 2a, 2b is formed on at least one of an inner peripheral side and an outer peripheral side of a base body 2 of bellows 1 by diffusion-bonding. Regarding the diffusion-bonding, the flat conductive coating layer 2a, 2b is layered on at least one end surface side of the plate-shaped base body 2, and these base body 2 and conductive coating layer 2a, 2b are diffusion-bonded. After forming this diffusion-bonded multilayer member into a tubular body by a drawing process, a side wall of the tubular body is formed into a bellows shape. With these processes, it is possible to obtain the bellows that has the conductive coating layer having a more uniform thickness on the base body of the bellows and has extremely good characteristics (the mechanical characteristics and the electric characteristics).
摘要:
At least one of the conductive members has a hollow storage portion that is formed at the conductive member and a communication hole through which the storage portion and the vacuum chamber communicate with each other, a getter is set inside the storage portion, and an adsorbed object such as metal particles and gas in a vacuum chamber is adsorbed by the getter. By prevent application of the electric field to the getter, even though the electric field appears in a vacuum casing, a temperature of the getter does not reach a re-release temperature, and also electron stimulus desorption phenomenon does not occur, then it is possible to prevent the metal particles and the gas etc. which have been adsorbed once by the getter from being released.
