Title: Head for magnetic recording and reproducing
Inventor: ANDO TAKASHI
IPC: G11B5/008
Filed: 1987-07-23
Abstract: PURPOSE:To enable the recording and reproducing of video signals to and from a compact cassette for audio use by setting the gap value in the front part of a magnetic head and the gap depth of the head to specific values and setting recording current at a prescribed value at the time of recording. CONSTITUTION:A spacer (glass resin, etc.) 5 is provided on a spacing part 4 between front end parts 2 and 3 of the magnetic head 1. The thickness lof the spacer is confined to <=0.8mu and the depth (d) of the gap to <=180mu. A winding 7 is wound on a core 6 formed of 'Permalloy(R)' and the thickness (t) of the core is set at 0.6mm and the inductance L of the winding 7 at 3mH. A chromium tape is used by taking the recording and reproducing time of a practicable level and mechanism part into consideration. FM recording is executed by specifying the tape speed at 38cm/sec and the band of the video signals at 250-300kHz. The high-frequency characteristic is thus improved and the characteristics suitable for practicability are obtd. at the time of recording the video signals by running the magnetic tape at the speed of several times higher than the ordinary speed.

Title: One-way clutch
Inventor: NAGATA TOORU
IPC: F16D41/12
Filed: 1981-11-17
Abstract: PURPOSE:To simplify the construction of a one-way clutch, by allowing a pawl, which is oscillated by a rotating input shaft, to mesh with and unmesh from the output shaft. CONSTITUTION:When the input gear 1 rotates clockwise, a boss 2c is pushed by one end of a cut part 1a to rotate a pawl member 2 counterclockwise round a shaft 3a, and thus a pawl 2b is put in engagement with a ratchet 4a. Thereby the input gear 1, pawl member 2 and ratchet 4a rotate clockwise as in a single body. When the input gear 1 turns counterclockwise, the boss 2c is pushed by the other end of said cut part 1a to rotate the pawl member 2 clockwise round the shaft 3a, and now the pawl 2b is disengaged from the ratchet 4a. Accordingly the ratchet 4a is free from transmission of the rotation of input gear 1.
