Title: Liquid crystal display device
Inventor: SAITO TAKESHI
IPC: G02F1/1345
Filed: 1987-10-02
Abstract: PURPOSE:To make a conductive pattern on a flexible substrate hard to break by supporting a buffer material without bending the flexible substrate. CONSTITUTION:A surface of the flexible substrate 5 is arranged in a plane including both its ends, connection parts for liquid crystal display elements 6, and a connection part for the printed board 14, and the connection parts at both ends of the flexible substrate 11 are supported through buffer materials 17. The flexible substrate 11 is therefore not bent, so the conductive pattern formed thereupon is not strained by bending and both end connection parts are supported through the buffer materials 17, so even if vibration or a shock is applied to the liquid crystal display device from outside, the device is neither vibrated nor given a shock. Consequently, the conductive pattern is not broken.

Filed: 1990-09-19
Abstract: PURPOSE:To easily execute the suitable switching of a call, channel and to prevent instantaneous interruption of a call by attenuating the signal of each radio zone in a tunnel and switching the call channel between the radio zones in the tunnel. CONSTITUTION:For an automobile going from one entrance/exit into a tunnel 3, the electric field of the signal from a base station 1 in open radio zone A is gradually attenuation with the advancement toward the inside of the tunnel 3. In the inside of the tunnel 3, the electric field is most weakened and in such a case, the call channel is immediately switched to that of another radio zone B. Afterwards, the electric field is gradually increased toward the other entrance/exit of the tunnel 3 and when the car goes outside from the other entrance/exit, radio waves can be directly received from a base station 2. Thus, the suitable switching of the call channel can be easily executed in the tunnel 3 and there is no problem such as hit of the call.

IPC: G11B7/00
Filed: 1988-10-05
Abstract: PURPOSE:To make the changing of emitted light quantity unnecessary and to reduce an error rate at the time of reproducing by controlling the amplitude and the DC potential of a signal inputted to a signal processing circuit so that they become an optimum value corresponding to the reflectance or the modulation factor of an information storage carrier, the light quantity of a light source and the like when they are changed. CONSTITUTION:A current signal from an optical head 2 is converted to a voltage signal by an I-V conversion circuit 3 and the amplitude of a reproduction signal 9 is detected by a gain control circuit 4. The amplitude of the output of the gain control circuit 4 is always made nearly constant by controlling gain so that the detected amplitude becomes sufficiently near a reference amplitude value. Besides, an offset control circuit 5 detects the offset level of a signal for detecting an offset level 54 and controls it so that it becomes sufficiently near a reference value. Then, the offset voltage of the output of the offset control circuit 5 is always made nearly constant. Thus, the amplitude or the offset level of the signal inputted to the signal processing circuit 6 can be made optimum without changing the laser light quantity and the error rate at the time when the signal is reproduced can be reduced.
