Title: Ultrasonic motor
Inventor: SAITO KOJI
IPC: H02N2/00
Filed: 1994-02-01
Abstract: PURPOSE:To provide an ultrasonic motor from which abnormal sounds are eliminated and which facilitates a high output. CONSTITUTION:A dynamic vibration absorber 21 is constituted by a spring system which is composed of a cantilever support rod 22 pushed into the outer circumference of an annular vibrating unit 15 and a mass system which is composed of a disc-type damper 23 fixed to the free end of the cantilever support rod 22. A plurality of the dynamic vibration absorbers 21 are attached to the outer circumference of the annular vibrating unit 15 with intervals of a center angle theta. The spacing between the adjacent dynamic vibration absorbers 21 with the center angle theta between them corresponds to the spacing between the adjacent peaks of the vibration mode of the annular vibrating unit 15 which causes the abnormal sound.

Title: Floppy head
Inventor: SANO KAZUTATSU
IPC: G11B5/56
Filed: 1984-02-21
Abstract: PURPOSE:To improve the tracking accuracy by supplying the outputs of both reproduction heads to a servo motor for head tracing and performing a tracking servo action. CONSTITUTION:A floppy head 1 contains a record/reproduction head 2, and this head 2 has two tracking servo reproduction heads 31 and 35 at the inner and outer sides respectively. In a reproduction mode the outputs of both heads 31 and 35 are detected while the recording is carried out by the head 2. In other words, a difference of output is produced between both heads 31 and 35 when a track shift is caused. Thus both outputs are supplied to a comparator, etc., and a servo motor is driven to obtain coincidence between both outputs. Then the head 2 is traced. Thus it is possible to perform the close recording with guard bandless of >=1,000TPI at most in terms of the tracking density.
