Title: Head assembly for vtr
Inventor: IRISA SHUNEI
IPC: G11B5/02
Filed: 1987-02-10
Abstract: PURPOSE:To decrease the number of channels of a rotary transformer, and to constitute it at a low cost by placing an auxiliary head having the same azimuth as that of the other head, at the upstream side in the vicinity of one head, and connecting them in parallel. CONSTITUTION:At the time of recording, a signal recorded by an auxiliary head 4 placed at the upstream side is recorded again by one head 3 placed at the downstream side, and recorded alternately by each different azimuth by this one head 3 and the other head 2. Also, at the time of reproduction, even if an auxiliary head 4 slide-contacts with a track recorded by the azimuth of one head 3, said signal cannot be reproduced because the azimuth is different but can be reproduced only by one head 3 placed at the downstream side, and in accordance with the azimuth, by one and the other heads 3, 2, reproduction is executed alternately. In such a way, as for a channel of a rotary transformer 15, two pieces will suffice, the number of channels can be decreased, the structure of the rotary transformer 15 is simplified, and also, it can be miniaturized easily.

Abstract: PURPOSE: To clean the durm surface without scratching it, by ejecting the developing fluid in a developing vessel from nozzles disposed each in front of a main blade and a sub-blade and further, by ejecting a replenishing solvent simultaneously from the nozzle in front of the main blade.  
     CONSTITUTION: Nozzles 17 and 16 are disposed in front of sub-blade 10 and main blade 11 in contact to photosensitive drum 1, respectively, and a developing fluid 6 sent from pump 15 is ejected from each nozzle 17 and 16, and further replenishing solvent 13a sent from pump 14 is ejected from nozzle 16 in front of the main blade at the same time. The toner remaining on the surface of drum 1 after transfer is almost washed off first with fluid 6 ejected from nozzle 17, and the residual toner is perfectly washed off with the developing fluid and the solvent from nozzle 16. This permits the toner having passed through sub-blade 10 not to be dried and the surface of drum 1 not to be scratched, in addition, the concentration of fluid 6 to be kept constant because fluid 6 and solvent 13a are mixed after washing and return to developing tank 5.

Title: High frequency transformer
Inventor: NOGUCHI SHOICHI
IPC: H01B7/30
Filed: 1987-02-13
Abstract: PURPOSE:To suppress the heat generated from a winding to a practical range by so bundling and twisting a plurality of fine leads as not to produce a central lead, and further so using bundled lead bundle formed by twisting a plurality of bundles as not produce a central bundle. CONSTITUTION:Since leads formed by bundling and twisting fine insulated conductors cross a magnetic flux in different ways according to the longitudinal position due to the twisting, the strong occurrence of a skin effect at the specific place in the strands or in the specific conductor of the twisted bundled conductors is suppressed. However, if there is the conductor disposed always at the center among a plurality of conductors or near it as the conventional one, the twisting effect cannot be obtained by such a conductor, a strong skin effect is presented, no current flows at the center, thereby generating heat. Then, one conductor bundle is constructed to eliminate the conductor disposed at a center as shown in Figs. (a) and (b) in the section of the bundled conductor bundle as shown in Figs. (c)-(e) to so bundle and twist them as not to generate the conductor bundle disposed at the center. Thus, the quantity of heat generated in the winding of a high frequency transformer can be reduced.
