    • A process for the production of mask frames for cathode ray tubes and is particularly useful in the production of color picture tubes for TV sets and monitors. The production of the frames is performed by welding at least two starting components, followed by forming, wherein planar starting components are positioned and fixed in positions in such way that edges of the starting components to be welded are in contact, followed by welding the starting components with at least one laser beam and, subsequently, processing the frame by pressing and/or punching. Preferably the laser beam is generated using a CO.sub.2 gas laser or a Nd:YAG solid-state laser. Preferably, the power of the laser beam is modulated to produce a weld that increases in depth from the beginning of the weld and decreases in depth at the end of the weld.

    • In the motor disclosed, five stator windings are distributed on u groups each having five main poles and coacts with a permanent magnet rotor. Each pole has n+1 pole teeth. The stator windings are connected in series or parallel to form five connecting points. A control switches five switches having an armature connected to a connecting point between a positive and negative potential so as simultaneously to energize the windings as required. The control then shifts the short-circuited condition to other windings in cyclical sequence while energizing the remaining four windings at any time. The pole divisions exhibit the relationshipsT.sub.P = nT.sub.S +.alpha.; .alpha.=T.sub.S (K+ 0.6).tau..sub.p ' = nT.sub.S +.beta. ; .beta.=T.sub.S (K'+0.6)the ratio of the rotor tooth widths to stator tooth widths at the outer diameter of the rotor is equal or smaller than unity. The number of rotor teeth Z.sub.R = u (5n+4K+K'+3). In this relation n, K, and K' are whole numbers and T.sub.P, T.sub.P ' and T.sub.S are pitches of adjacent main poles on adjacent groups and of adjacent pole teeth. The angles .alpha. and .beta. are pitches between adjacent teeth on adjacent poles and adjacent groups. The control means connect the windings so as to permit operation in one of five stepping angle modes and in a five phase or two phase mode.

    • A stepping motor of the homopolar design with a step angle of 3.6.degree. and having a generally cubic form is disclosed. The motor includes a generally square, single-section laminated stator which has only four stator poles extending radially inwardly from the middle regions of the straight sides, and a concentric rotor secured to a shaft journaled in a pair of bearing bells fixed to the stator at the opposite faces thereof and having the same generally square configuration. The rotor includes a disc-shaped permanent magnet of high remanent energy density (B.times.H).sub.max .gtoreq.10.times.10.sup.6 GOe, and a pair of annular steel rotor elements provided at the working air gap with identical numbers Z.sub.r of rotor teeth of pitch .tau..sub.r =360.degree./Z.sub.r. Each stator pole is provided at the working air gap with four or five stator pole teeth of pitch .tau..sub.s =360.degree./Z.sub.s, where Z.sub.s is the theoretically maximum available number of stator pole teeth and must be evenly divisible by 4, and Z.sub.s =Z.sub.r -1.+-.k where k is an even integer and 0.ltoreq.k.ltoreq.6. A special twin-section insulation member adapted to be axially fitted into the stator from the opposite faces thereof and designed to permit simultaneous machine winding of the field windings onto the respective stator poles is also disclosed. This abstract is not to be taken either as a complete exposition or as a limitation of the present invention, however, the full nature and extent of the invention being discernible only by reference to and from the entire disclosure.
