摘要:
Charged particle energy analysers enabling simultaneous high transmission and energy resolution are described. The analysers have an electrode structure (11) comprising coaxial inner and outer electrodes (14, 15) having inner and outer electrode surfaces (IS, OS) respectively. The inner and outer electrode surfaces are defined, at least in part, by spheroidal surfaces having meridonal planes of symmetry orthogonal to a longitudinal axis of the electrode structure (11). The inner and outer electrode surfaces are generated by rotation, about the longitudinal axis, of arcs of two non-concentric circles having different radii R2 and R1 respectively, R2 being greater than R1. The distance of the outer electrode surface from the longitudinal axis in the respective meridonal plane is R01 and the distance of the inner electrode surface from the longitudinal axis in the respective plane is R02 and R1, R2, R01 and R02 have a defined relationship.

The rotary cathode X-ray tube equipment of the present invention is constructed so as to permit radiation of X-ray from all directions with respect to the whole circumference of a subject, and is used for x-ray CT. The equipment of the invention is constructed to prevent an X-ray radiation window 40 of a low strength from being influenced by atmospheric deformations of a vacuum vessel 1 or by machining and assembling errors, for example by using a joint portion disposed between the X-ray radiation window and an inner ring and having both a surface perpendicular to a rotational axis of a rotary member and a cylindrical surface parallel to the rotational axis, a face seal formed on the surface of the joint portion perpendicular to the rotational axis, and an axial seal formed on the cylindrical surface of the joint portion parallel to the rotational axis.

A mounting member has a tube, and a plurality of clamps. The clamps hold the tube or outer portions on both sides of the tube. Therefore, the external load on the mounted part can be minimized while at the same time the mounted part is easily held fixedly on a board such as a printed wiring board.
摘要:
In a multipole linear accelerator such as of a quadrupole type, fine positional adjustment of the tip portions of the electrodes constituting the multipole structure can be made with electric contact kept substantially unaffected between the electrodes and the cavity drum in which the electrodes are mounted. Each of the electrodes are provided with a series of contact plates on both sides of the root portion of the electrode over the whole length thereof. Each of the contact plates, which are held to the root portion of the electrode by means of an adjusting screw bolt, slantwise bridges the root portion of the electrode and the inner surface of the cavity drum with elastic contact pieces interposed. Tightening or loosing the adjusting screw bolts on both sides of the electrode displaces the electrode with electric contact kept unchanged between the electrode and the cavity drum by the elastic effect of the above contact pieces made to interpose between the contact plates and both the electrodes and the cavity drum.

摘要:
A connecting terminal has an electrically-conductive ring surrounding a columnar space. Electrically-conductive elastic pieces extend from the electrically-conductive ring in the direction of the central axis of the columnar space. Electrically-conductive blades stand from the outer surfaces of the electrically-conductive elastic pieces. A lead terminal is received in the columnar space. The tip ends of the electrically-conductive elastic pieces are urged against the lead terminal. The lead terminal is prevented from withdrawing out of the through hole. Electric connection is established between the lead terminal and the elastic pieces. The blade or blades of the connecting terminal or terminals stick into the wall surface of the through hole. The connecting terminal is thus firmly held in the through hole. Electric connection is established between the blade or blades and the through hole. Electric connection is thus established between the lead terminal and the through hole.
