Title: Liquid crystal display system
Inventor: FUJII YASUHISA
IPC: G09F9/00
Filed: 1990-08-29
Abstract: PURPOSE:To allow the keeping of the secrecy of display contents by including a liquid crystal device having a polarizing plate only in the deep side of a liquid crystal layer and spectacles consisting of polarizing plates and viewing the display contents of the liquid crystal device through this spectacles. CONSTITUTION:Circularly polarized light is transmitted from glass 15 and, therefore, images are invisible at this time. This circularly polarized light is polarized from the circularly polarized light to linearly polarized light by the polarizing plates 21a and 21b in front of the eyes provided on the spectacles 22. Then, the viewing of the light in the form of images is possible and, therefore, only the person wearing the polarizing plates in front of the eyes can view the display information.

Title: Detecting circuit for tracking error
Inventor: KATAGIRI TOSHIYUKI
IPC: G11B5/592
Filed: 1982-12-27
Abstract: PURPOSE:To shorten an unstable operation period in composite shooting by obtaining a tracking error signal from the beats of the pilot signals of adjacent tracks produced by crosstalk and the own pilot signal obtained from a track which is under tracing. CONSTITUTION:An amplifier 12 amplifying the pilot signal extracted by an LPF2, and a limiter circuit LIM13 shaping the waveform of the pilot signal and making the amplitude uniform are provided. The pilot signal outputs (f1-f4) passed through this tracking error detecting circuit of 4-signal system are mixed with the output of the LPF2 by a mixer MIX4. Thus two beat components (frequency differences fT1 and fT2) are produced from said mixture and extracted through BPF5 and 6 respectively. Then the output of control signal (error signal) is obtained from the outputs of the beats. This circuit eliminates the selecting/ switching control for four signal frequencies f1-f4 which are mixed by the mixer.

Title: Separating device for take-up roll during rotational transfer
Inventor: OGAWA MASAYUKI
IPC: B65H19/30
Filed: 1998-08-12
Abstract: PROBLEM TO BE SOLVED: To prevent take-up rolls from coming into contact with each other by increasing a space between their end sides in rotating and transferring a plurality of take-up rolls with ends adjacent to each other. SOLUTION: A plurality of separating plates 13 are arranged in one row and connected to each other by means of connecting hardware fitted with a stopper for restricting a space due to the mutual movement of the separating plates. A guiding device is provided which guides the separating plates so that they may be movable in the arranged direction. Actuators 11 are mounted on the respective separating plates positioned at both ends of the line of isolating plates and their operation is controlled by a controlling device 12. When a plurality of take-up rolls 1 with ends adjacent to each other rotate for transfer and pass on a plurality of separating plates in an orthogonal direction to the line of the separating plates, the operation of the actuators permits the separating plates to move for increasing the space between the separating plates.  It is thus possible to increase the space between the take-up rolls.
