Title: Magnetic recording and reproducing device
Inventor: IKEDA SUSUMU
IPC: G11B15/14
Filed: 1985-06-26
Abstract: PURPOSE:To realize a consecutive recording for generating no color beat by detecting a 90 deg. delay or an output amplitude of a preceding head with respect to an original reproducing head of a small diameter cylinder having total four pieces consisting of two kinds of video heads of two pieces each, and providing a recording switching circuit for switching from reproduction to recording. CONSTITUTION:A capstan motor 27 is controlled so that a reproducing control signal which has been reproduced from a control head, and a recording control signal which has been generated from an input video signal coincide with each other. Also, whether an output exists in a 90 deg. delay head at a point after 8ms from a rise edge of a head switching signal or not is always detected, and while the output exists, it is a recorded part and remains a reproducing state. When reproduction is continued for about 0.8sec, it becomes the last track which has been recorded, and in this case, the output of the 90 deg. delay head becomes zero. Accordingly, after the output of the 90 deg. delay head has become zero, the device is switched to a recording mode from a fall edge point of the first head switching signal. In case of these recording and reproduction, the most important timing matching is processed by a recording timing circuit 43.

Title: Heat insulating material
Inventor: MIZUKAMI YOSHIKATSU
IPC: B32B7/02
Filed: 1996-05-08
Abstract: PROBLEM TO BE SOLVED: To inexpensively obtain an agricultural heat insulating material, especially, a water absorbable heat insulating material for cultivativing a strawberry by laminating a porous film and a nonwoven fabric and setting the absorbing speed of waterdrops dripped on the rear surface of the film to specific sec or less. SOLUTION: A heat insulating material is constituted by laminating a porous film and a nonwoven fabric. The absorbing speed of waterdrops of this heat insulating material is set to 60sec or less. When the absorbing speed of waterdrops exceeds 60sec, the absorbing speed becomes markedly slow because of partial irregularity or possibility not perfectly absorbing waterdrops is partially generated. The average pore size of the porous film is set to about 10-1,500μm. If the average pore size is small, the absorbing speed of generated dew becomes low and, if the average pore size becomes too large, the heat insulating effect of the film becomes low. Therefore, waterdrops dripped on a strawberry is rapidly removed and the damage ratio of a strawberry is lowered and yield is enhanced.  Further, the absorption of the radiant heat of the heat of the earth is good and heat insulating effect and heat transfer are well-balanced and, therefore, the total heat insulating effect is enhanced.
