Title: Optical reproducing magnetic recording medium and recording and reproducing apparatus
Inventor: TAKEKOSHI TARO
IPC: G11B13/04
Filed: 1992-04-16
Abstract: PURPOSE:To stabilize focus and track servo characteristics and also improve reliability of apparatus by joining a magnetic medium to an optical disk as an optical reproducing region through an intermediate layer consisting of a soft material member. CONSTITUTION:A recording and reproducing apparatus has a structure that an intermediate layer 20 having viscous and elastic properties is sandwiched between an optical disk 10 and a magnetic medium 30. Therefore, resonance of the optical disk 10 can be suppressed. In this case, if the optical disk 10 resonates, a partial position deviation is generated against a magnetic medium 30. Accordingly, a fine deformation is generated on the intermediate layer 20 sandwiched by these elements. But since the intermediate layer 20 has the viscous and elastic characteristics, such fine deformation is suppressed. As a result, the intermediate layer 30 is also provided with a function as a damper and thereby does not easily resonate.

Title: Manufacture of polybutene resin pipe
Inventor: KAJIWARA YASUSHI
IPC: B29C48/32
Filed: 1990-04-11
Abstract: PURPOSE:To make it possible to make the final roll diameter smaller without developing flattening and buckling by a method wherein the pipe concerned is wound up in larger diameter under the state that the pipe is just after forming and its strength is low, and then wound up in smaller diameter under the stage that the transition percentage of the resin of the pipe reaches the specified percentage or higher and consequently winding vice reduces. CONSTITUTION:Just after pipe-forming, polybutene resin pipe is wound up in a coil diameter, which is 40 times or more as large as the outer diameter of polybutene resin pipe and lies within the range of 1-4m. After the solid phase transition of polybutene resin proceeds over 70%, said wound-up coil is re-wound up in a coil diameter, which is 15 times or more as large as the outer diameter of the polybutene resin pipe and lies within the range of 0.5-1.7m. Thus, flattening percentage becomes extremely small and the radius, at which duckling develops, becomes smaller. The flattening of the pipe can be prevented from developing. The winding-up in the minimum diameter, at which neither winding vice nor buckling develops, can be realized and transportation cost becomes small and, further, the polybutene resin pipe roll can be carried by one person alone at construction site.
