Filed: 1998-11-20
Abstract: PROBLEM TO BE SOLVED: To provide a magneto-optical head device and a magneto-optical reproducing method for performing magnetic ultra-resolutional reproduction while obtaining a high regenerative signal S/N. SOLUTION: A magneto-optical disk 1 is irradiated by a parallel beam of (p) polarization to reflect it. The reflected beam is reflected by a first beam splitter 14 to be supplied to a regenerative signal detection system 20. The reflected beam is supplied to a light shield plate 21, and a (p) polarization component transmits through an area of a polarizing film 21b at a transmissivity of nearly 100%, and an (s) polarization component transmits at a transmissivity of nearly 0%, that is reflected or absorbed to be light shielded. The beam transmitting through the light shield plate 21 is made incident on a polarizing beam splitter 19 to be divided to the (p) polarization component and the (s) polarization component, and the regenerative signal is differential-detected.  Since outputs of photodiodes 22, 23 are proportional to optical power, and not to optical amplitude, the more a beam quantity transmitting through the light shield plate 21 is, the larger the regenerative signal itself becomes, and the S/N is improved.

Title: Tape tension controller
Inventor: TONOMURA TETSUYA
IPC: G11B15/43
Filed: 1987-12-28
Abstract: PURPOSE:To easily control tape tension even at the time of rewinding travel by providing plural pieces of projecting parts to be pressed on a brake belt. CONSTITUTION:At the time of rewinding (REV), the brake belt 10 moves in a reverse direction to that at the time of PLAY, and a pressing pin 19b on a tension arm 78a comes into contact with the part to be pressed 18b projecting from the brake belt 10. In this state, the tension arm 7a maintains the balance of the movement of force around a supporting shaft. Then, if the tape tension comes larger than a set value, because the pressing force of the pressing pin 19b is increased, and braking force is increased as well, and the winding torque of a reel stand is decreased, the tape tension is decreased. On the contrary, if the tape tension comes smaller than the set value, the pressing force of the pressing pin 19b is decreased, and the braking force is decreased as well, and the winding torque of the reel stand is decreased, and the tape tension at the time of REV is controlled. Thus, the tape tension can be easily controlled even at the time of REV.

Filed: 1989-12-21
Abstract: PURPOSE: To minimize adverse interactions between an abradable seal and an engine movable constituent element during initial engine operation by applying a thin layer of colloid particles of ceramics to the engine movable constituent element. CONSTITUTION: An outer air seal 4 is arranged on an inner case 3 and adjacent to a tip of a blade 2, and an inner air seal 7 is arranged on a tip 6 of a vane 5.
