Abstract: PURPOSE:To enhance the transmission of electron beams by more weakening the peak value of flux density over the center axis of one section the half period of the magnetic circuit of which is long, than the peak value of flux density over the center axis of the other section by the value of a specified amount. CONSTITUTION:The thickness T1 of a permanent magnet 8 at an input/output coaxial configuration section is made thicker than the thickness T2 of the other permanent magnet 7. Since all magnet poles are constant in thickness which is, in this case, T3, the half period L1 of a magnetic circuit at the input/output coaxial configuration section is longer than the half period L2 of a magnetic circuit at the other section. In this constitution, the peak value of flux density over the center axis at a position (section for half period L1) where the half period of a magnetic circuit is made long, is more weakened than the peak value of flux density over the center axis at the other section by 50 to 200 Gauss. This can thereby enhance the transmission of electron beams. In addition, even in a travelling wave tube which requires a periodical magnetic field which is operated at high frequencies and short in period, the input/output coaxial section can be connected to a slow wave circuit section with ease.

Title: Production of rubber gasket for immersed tube joint part
Inventor: TAKANO NOBUKAZU
IPC: B29C65/70
Filed: 1996-01-11
Abstract: PROBLEM TO BE SOLVED: To simplify a buff process for preventing the peel and destruction of an adhesive part to a large extent by peliminarily embedding canvas easy in the peeling with vulcanized rubber in a surface vulcanized and bonded later at a time of the bonding processing of a rubber gasket to perform vulcanization. SOLUTION: At first, a main split part 1 is molded. At this time, oxford cloth canvas (made of PET) 2 easy peeled from vulcanized rubber later is embedded in both end surfaces of a part bonded at least later to perform molding and vulcanization. Next, the oxford cloth canvas 2 embedded in the bonding surface is peeled off. Since the peeled surface shows an uneven surface suitable for bonding, buffing is not especially required and a flash surface is obtained. A rubber sheet of which the sulfur amt. is larger than a main body gasket of about 5-8mm, for example, by 2PHR is bonded to the entire surface of the bonding surface to be vulcanized and bonded. The rubber gasket thus obtained for an immersed tube joint part develops sufficient cut-off properties.

Title: Method and device for generating x-ray microbeam
Inventor: IZUMI KOICHI
IPC: G01N23/20
Filed: 1997-01-10
Abstract: PROBLEM TO BE SOLVED: To establish a method for generating an X-ray microbeam which keeps the degree of asymmetry and the condensing factor at a constant value even if the wavelength of X rays changes by changing angles of incidence and outgoing to the surface of a crystal with the Bragg condition maintained by rotating the crystal around an axis perpendicular to the surface of a reflecting grating. SOLUTION: An asymmetrical factor due to the fluctuation in the energy of X rays is maintained constant to make it possible to scan the energy of incident X rays without changing condensing efficiency. If is also possible to keep the degree of asymmetry at a constant value even if the wavelength of selected X rays changes. Furthermore, a condensing condition including the energy and beam size of X rays can be set independently. Therefore, such difficulties as the change in the degree of asymmetry and condensing efficiency can be solved. An asymmetrical factor due to the charge of the energy of X rays can be maintained uniformly and it is made possible to scan the energy of incident X rays without changing condensing efficiency by varying angles of incidence and outgoing to the surface of a crystal without disturbing the Bragg condition through the rotation of the crystal.
