Title: Optical information recording and reproducing device
Inventor: SEKIGUCHI TAKETO
IPC: G11B20/10
Filed: 1987-12-25
Abstract: PURPOSE:To improve the amplitude margin and to improve the recording density by generating a gate signal from a read edge signal based on a viable threshold level obtained from a DC variant comprised in the read edge signal. CONSTITUTION:1st and 2nd detection circuits 41 and 42 detect positive and negative envelopes out of the read edge signal, whereas from both detecting levels, a threshold value generating circuit 43 generates a threshold level capable of binarizing automatically in the middle part of the read edge signal in the amplitude direction. Then, a gate signal detecting comparator 44 compares the threshold level with the read edge signal and outputs the gate signal accordingly. By this method, a lack of the gate signal and a fluctuation in pulse width can be prevented, thus improving the amplitude margin.

Title: Electro-magnetic shield blind
Inventor: KAWASAKI KIMIO
IPC: E06B9/24
Filed: 1996-12-10
Abstract: PROBLEM TO BE SOLVED: To selecting only radio waves of a necessary frequency to shield other radio waves, by arranging periodically linear antennas patternized on light-shield plates or light-shielding films constituting a blind, taking a magnetic field absorption-equivalent area which the antennas have, into consideration. SOLUTION: Y-shaped small linear antennas 5 as a circuit pattern are periodically arranged on slat 1 faces as light-shielding plates, taking a magnetic field absorption-equivalent area which the antennas have. As a method to arrange patternized small linear antennas on synthetic resin slats 1, a silk printing, a pattern pressure adhesion, etc., are used for instance. When a conductor piece is existing in the air, if this face receives incident radio waves, a part thereof passes through the face and other radio waves are reflected. The attenuating characteristic of the transmissible waves depends on the shape of the conductor piece. When the conductor piece is a dipole shape, the received electric power is partly radiated again and a quarter of the power is absorbed into the linear antenna conductor as a heat loss.
