Abstract: PURPOSE:To perform high-density recording excellently even at a tape running speed other than a standard speed and to perform excellent reproduction by recording an audio modulated signal on a track for a video signal, and then recording a luminance modulated signal and a chroma low-frequency signal on the same track one over another. CONSTITUTION:A couple of audio heads 24 and 25 which have an interval of 180 deg. and mutually different azimuth angles are disposed on a cylinder 19 at an angle alpha1 from standard-speed video heads 20 and 21 and at an angle alpha2 from low-speed video heads 22 and 23. Then, the angles alpha1 and alpha2 and steps Td1 and Td2 are specified as shown by inequalities I and II, where Tp1 and Tp2 are track pitches. Consequently, the audio modulated signal is recorded firstly and the video signal is then recorded thereupon excellently in both modes to record the audio modulated signal deeply in a tape magnetic layer; and the luminance modulated signal is recorded on the surface of the magnetic layer without erasure.

Title: Brush device
Inventor: YOSHIKAWA SHOICHI
IPC: H02K23/00
Filed: 1997-08-18
Abstract: PROBLEM TO BE SOLVED: To obtain a brush device which restrains an abnormal sound generated due to the vibration of a brush, by a method wherein a vibration absorption mechanism is fixed to the brush so as to be movable. SOLUTION: When a brush 13 is slid with a commutator C so as to be subjected to a frictional force, the brush 13 is vibrated when the frictional force is increased. At this time, since a weight 14a as a moving part in a vibration absorption mechanism 14 is fixed to the brush 13 so as to be movable, the weight 14a is moved together when the brush 13 is vibrated. At this time, a pressure sensitive adhesive 14b as an energy conversion part which is interposed between the brush 13 and the weight 14a is deformed, and heat energy is discharged. That is to say, when the weight 14a is vibrated while it is being dislocated with reference to the brush 13, the vibration energy of the brush 13 is absorbed. As a result, the vibration of the brush 13 is converged, and a noise which is generated due to its vibration is prevented.
