IPC: H01F1/36
Filed: 1998-04-20
Abstract: PROBLEM TO BE SOLVED: To easily obtain a magnetic path which is optimal for the state at-site use by reducing iron loss and noise. SOLUTION: When a bonding end surface portion in a step lap joint of an iron core is impregnated with a gel type material 5 into which magnetic particles 6 are mixed, magnetic flux in the iron core forms a transition magnetic flux 8A which reaches an opposite facing iron plate 9b from one side iron plate 9a via an iron plate 9c which is laminated together with the iron plate 9a, and forms a transition magnetic flux 8B which reaches the opposite facing iron plate 9b from the one side iron plate 9a via a gap 7 on the same surface. Thereby the local concentration of magnetic flux can be relaxed, as well as the prolongation of magnetic path can be restrained, and magnetic resistance can be reduced, so that iron loss and noise can be reduced.

Abstract: PURPOSE:To control current supply to a driving source, make the front curtain and rear curtain of shutter traveling at a constant speed during expodure and prevent an image from uneven exposure by detecting counter electromotive force generated in an electromagnetic driving source at the time of shutter traveling. CONSTITUTION:In a shutter of this invention curtain speed is gradually increased similarly with a curve A during the period from a travel starting point 0 to t1.
