Filed: 1990-01-25
Abstract: PURPOSE:To obtain a motor which can be assembled easily by extending the end of a winding wound around a doughnut type stator core toward one side in the axial direction, mounting a printed board on the side face, opposing the printed wiring to the outer circumferential edge of the printed board and then connecting the end of winding to the printed board. CONSTITUTION:A doughnut type stator core 1 is applied with a winding 3 thus forming a toroidal winding. End of the winding 4 is lead out to one side of the stator core 1. A printed board 5 is arranged on the winding end 4 side of the stator core 1 and the end of winding is is held by and connected with protrusions and recesses, formed at the outer circumferential edge of the printed board 5, and a printed wiring. By such arrangement, mechanical assembling can be realized. When the winding 3 and the printed board 5 are covered with resin 6, the end of winding 4 is not shifted by the poured resin because the distabe between the end of winding 4 and the printed board 5 is short and thereby disconnection of winding can be prevented.

Filed: 1982-01-29
Abstract: PURPOSE:To reduce the distortion of an input, by extracting one output from each of three sets of high-frequency conversion circuits, by composing the same in series, and by subjecting it to all-wave rectification and smoothing. CONSTITUTION:When three-phase power sources e1, e2 and e3 are inputted, output voltages v1, v2 and v3 of high-frequency conversion circuits 1, 2 and 3 are synchronized by a synchronous signal of a synchronization circuit 5 respectively, and the peak values of these voltages are made proportional to the absolute values of instantaneous values of the power sources e1, e2 and e3. Accordingly, a composite output voltage vout obtained by composing theses output voltages v1, v2 and v3 in series is a high-frequency voltage having a peak value of a prescribed level. This composite output voltage vout is subjected to all-wave rectification by a rectifying-smoothing circuit 4 to be converted into a smooth direct current. By this constitution, each output is supplied to a load without discontinuation, and thereby distortion and the like can be reduced.

Then a support arm 11 swings to move the print head 1, and an ink ribbon R made to overlap a receptor tape 6 is held between and pressed by a platen roll 5 and the print head 1. When a take-up core 9 and others rotate, the ink ribbon R runs and printing is made on the receptor tape 6. Thereafter the ink ribbon R is taken up sliding in contact with a guide member 2. In this case, the guide member 2 is moved aslant in the width direction of the ribbon being reverse to the direction of a slant motion of the print head l, with the sliding contact. Thereby a tensile force generated with running of the ink ribbon R is dispersed in the width direction of the ribbon.

IPC: G03G15/00
Filed: 1981-02-02
Abstract: PURPOSE:To prevent the dropout and disturbance of images and to improve image reproducibility by binding photoconductive fine powder with a resin and using a photoreceptor subjected to a smoothing treatment to <=3mum smoothness as an electrostatic latent image carrier. CONSTITUTION:A photosensitive drum 1 consists of photoconductive fine powder CdS.nCdCO3 which is bound with a thermosetting acrylic resin and is polished by buffing on the surface. Smoothing treatments which are normally known other than the above-mentioned polishing by buffing may be practised for the smoothing treatment to be applied on the surface of the drum 1. It is also possible to execute the smoothing treatment by coating a resin equal to the binder resin on the surface of the photoreceptor. AC bias voltage is applied from an AC bias power source 13 to a developing sleeve 10. Thereby, the discharge phenomena among the polarized toner particles is stabilized, and therefore the generation of the dropout and disturbance of images is obviated.
