Title: Transformer
Inventor: KOBAYASHI KEIICHIRO
IPC: H01F27/24
Filed: 1990-06-06
Abstract: PURPOSE:To omit a bobbin, to realize a small size and to increase a capacity by a method wherein a yoke is divided and a coil is wound directly on a central leg. CONSTITUTION:A magnetic core 11 is divided into a magnetic-core part 11a and yoke parts 11b. Consequently, when a transformer is assembled, a coil 3 is wound directly on a central leg 5 and, after that, the yoke parts 11b are fixed to the magnetic-core part 11a. Thereby, a bobbin is not required, the transformer can be made small-sized and it is possible to increase the capacity of the transformer by increasing the effective cross-sectional area of the magnetic core. Since the bobbin is omitted, costs are lowered and the number of assembly processes is reduced by eliminating a bobbin insertion process.

Filed: 1985-07-05
Abstract: PURPOSE:To correct fluctuation in light axis readily, by introducing a simulation laser beam into an unstable type resonator, and arranging a beam-angle correcting mechanism and a beam-angle detector on a path of the laser beam. CONSTITUTION:A simulation beam 15 is supplied through a small hole in a concave mirror 31 and reciprocated between a convex mirror 32 and the concave mirror 31. Thereafter, the beam is projected to the outside of an unstable resonator by a beam taking out mirror 33. The angle of the light axis of the projected simulation beam is detected by a beam angle detector 16 through a plane mirror 14. The detected signal is inputted to a signal processing and motor driving circuit 17. The circuit 17 drives an angle controlling motor 131 in an beam-angle correcting mechanism 13. Thus the plane mirror is turned. The fluctuation in light axis of the simulation beam due to thermal deformation of an oscillator cabinet 1 is corrected in this way. This is equivalent to the correction of the fluctuation in light axis of the laser beam projected from the laser light source apparatus.
