Abstract: PURPOSE:To cope with the production of many kinds in small quantities by forming a tooth form part on the outer periphery of a ring-shaped work and protrusions for calking on the inner periphery, inserting the protrusions for calking into holes for calking of a circular plate and fixing the ring-shaped work to the circular plate by striking/pressing. CONSTITUTION:In the 1st press die forging stage, a tooth form part 41 is formed in the outer peripheral part of the ring-shaped work and a boss part is formed on the inner periphery. In the 2nd press die forging stage, a tooth form 42 and the protrusions 4a for calking are formed on the ring-shaped work. Specular finishing is applied to a die for forming the tooth form 42. Next, in a trimming stage, excess metal parts which are generated on the outer and inner peripheries of the ring-shaped work are drawn out. In a calking/distortion relieving stage, a drive plate is manufactured by inserting the protrusions 4a for calking of the ring gear 41 into the holes 46 for calking which are pierced in the circular plate 45, crushing the protrusions 4a for calking by striking/pressing with a calking punch 49 and fixing the circular plate 49 to the ring gear 41. Simultaneously distortion is removed.

Title: Direct drive type tape recorder
Inventor: HITOMI TADASHI
IPC: H02K7/14
Filed: 1985-04-05
Abstract: PURPOSE:To secure the sufficient torque to drive a tape by transmitting and adding together the revolving torque produced when each flywheel is driven via a transmission member. CONSTITUTION:The revolving forces of flywheels 1 and 2 are transmitted by drive gears 12 and 13 via transmission gear 14 and 15. Thus two gears 14 and 15 are used and also drive coils 10a-10d and 11a-11d are wound so as to drive both wheels 1 and 2 opposite to each other. Thus the torque produced by both wheels 1 and 2 are set in the same direction. Then the torque of both wheels 1 and 2 are added to each other and doubled revolving torque is applied to the wheel 1 or 2. Thus the sufficient torque is obtained for drive of a tape even in case the increase of diameter is impossible owing to a small space.
