IPC: H01J25/12
Filed: 1990-03-28
Abstract: PURPOSE: To provide a klystron amplifier tube whose overall length is shortened by increasing a diameter of a drift tube with respect to a diameter of a beam. CONSTITUTION: In a hollow 26, a metallic body part or an envelop covering a beam 10 is spread to a larger diameter part 46 from a hole 22 in an interaction clearance 28. As a drift tube in the clearance is widened further in the part for the clearance, a shield factor is reduced while repulsion force is increased, so that a space charge wavelength is reduced. As a proper length for a klystron is decided on the basis of the space charge wavelength, a physical length of an amplifier tube is reduced as a result. In this way, a length of the klystron is reduced, and a size of a device, a dimension of a magnet, weight and a cost can be reduced.

Title: Magnetic tape
Inventor: KAWAMURA SATOSHI
IPC: G11B5/73
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To prevent a magnetic tape from being deteriorated in the running performance during the use in numerous times by restricting the curvature of the magnetic tape in the longitudinal direction within a specific range. SOLUTION: The formation of mirror-like surface depends on the contact surface pressure at the time of sliding operation of the magnetic tape with a head drum, and the contact surface pressure depends on the curvature of the magnetic tape in the longitudinal direction. So, the increase in the friction due to the sliding of a magnetic surface of tape against the outer peripheral surface of the magnetic head drum is suppressed by means of specifying the range of curvature of the magnetic tape in the longitudinal direction. That is, the optimum contact pressure is obtained by specifying the curvature of magnetic tape in the longitudinal direction to the range of -1.5mm-+ 3.0mm. When the curvature is <-1.5mm, the friction is increased, and when it exceeds +3.0mm, the contact failure is generated and the electromagnetic conversion characteristic is deteriorated. Consequently, by restricting the curvature of magnetic tape in the longitudinal direction in the range of -1.5mm-+3.0mm, the contact surface pressure between the magnetic head drum and magnetic tape is optimized to suppress the increase in the friction, then the running performance is improved over a long period.
