Title: Magnetic recording and reproducing device
Inventor: MIHASHI YASUO
IPC: G11B5/53
Filed: 1983-11-29
Abstract: PURPOSE:To improve the S/N in the overwriting system as much as possible by providing a magnetic head for recording and reproducing and a magnetic head which erases parts of overwriting and insulating magnetically rotary transformers, which are connected to these magnetic heads, from each other to provide rotary transformers independently of each other. CONSTITUTION:A device is so constituted that the second rotary transformers 15a and 15b take charge of the second magnetic heads 2a and 2b and the first rotary transformers 16a and 16b take charge of the first magnetic heads 8a and 8b. An overwriting part T' is erased by the first magnetic head 8a just before a signal is recorded there by the second magnetic head 2a. As the result, a no- signal recording part T is formed after erasing due to the first magnetic head 8a, namely, between scanning of the first magnetic head 8a and that of the second magnetic head 2a. This no-signal recording part T is in the same state as erasing due to a fixed erasing head 6, namely, in the completely erased state, and signals recorded in the preceding scanning by the second magnetic head 2b do not remain at all. Consequently, noise is not extracted from this part at a reproducing time, and the S/N is not degraded.

Title: Method and apparatus for twisting thermosetting resin molded item
Inventor: TOKUNAGA YOSHINORI
IPC: B29C53/80
Filed: 1990-08-28
Abstract: PURPOSE:To enable large twist processing to be performed although it is difficult by a conventional manner by applying a fixed range of torque which does not exceed a breakdown pint significantly as does yield torque, to a work to be processed at higher than a glass transition point and at the same time, increasing a twist processing amount gradually. CONSTITUTION:A material 1 is fixed between a fixing bracket 2 and a torque application fixture 3 so that no play is present in a twisting direction. The fixing bracket 2 is firmly fixed, and the torque application fixture 3 rocks in twisting direction due to a stepping motor 6. In this case, torque is measured by a torque meter 6 and a rotating angle is measured by a rotary encoder 7. The material 1, the fixing bracket 2, and the torque application fixture 3 are maintained at a higher temperature than the glass transition point Tg of the material 1 in a furnace 12. The stepping motor 4 is allowed to rock continuously by a control device 11 so that an upper dead point torque T2 and a lower dead point torque T1 are constant. If the twisting angle thetaat the time of the lower dead point torque T1 becomes a specified value due to the plastic deformation of the material 1, the stepping motor 4 stops and the material 1 is twisted into a specified shape.
