Title: Hologram three-dimensional path chart
Inventor: MATSUYAMA TETSUYA
IPC: G03H1/24
Filed: 1998-11-30
Abstract: PROBLEM TO BE SOLVED: To three-dimensionally display the intersection of paths and to intuitively clearly connect a departure point and an arrival point so as to easily understand them by recording the crossing paths as a volume type hologram so that the paths are mutually three-dimensionally reproduced at upper and lower positions. SOLUTION: By irradiating a Lippmann hologram 10 photographed by using a three-dimensional model made by using plural wires so that they may three- dimensionally cross with white illuminating light 20 from the incident side of reference light at the time of photographing, diffracted light(reproduced light) 22 is generated on a reflection side from the hologram 10. When an observer views the diffrated light 22 with his(her) eye E, he(she) views a reproduced image M' being the same stereoscopic image as a virtual image at the position of the three-dimensional model at the time of recording. By using the hologram 10 as the path chart, the intersections P1, P2 and P3 of the grating like paths 21 like lines arranged crosswise are stereoscopically viewed, and the observer instantly understands what paths are connected with each other and what paths are separate paths and are not connected.

Abstract: PURPOSE:To realize ordering line communication between two points where a transmission side is apart from a reception side by using a changeover switch provided on each MODEM of the transmission side and the reception side to switch a main voice signal and an ordering line voice signal and sending the ordering voice signal with a radio wave. CONSTITUTION:An ordering signal transmitted through a cable CT passes through an ordering signal band pass filter 16a and a band pass filter 15 in a transmission side MODEM section 1, an amplitude demodulation circuit 12 demodulates the signal, an amplifier circuit 11b amplifies the signal to obtain an ordering line voice signal output. Thus, the ordering between the transmission side MODEM section 1 and a transmission side radio high frequency section 5 is implemented. Furthermore, the transmission side MODEM section 1 is provided with an ordering line voice signal synthesis circuit 9, which synthesizes the voice signal of the ordering line sent to the radio high frequency section 5 and the ordering line voice signal received from the radio high frequency section 5. Thus, a changeover switch 10 is switched to the position of the ordering line in the case of transmission of the ordering line voice to send the signal to the reception side.

Filed: 1995-12-04
Abstract: PROBLEM TO BE SOLVED: To realize a method and a circuit for differential amplitude detection which remove a differential offset error from a differential data signal received from a transmission line. SOLUTION: A differential amplitude detection circuit 10 allows positive and negative components of a data communication differential signal to pass peak detection circuits 12 and 26 respectively. Peak detection voltages are held in first and second nodes 15 and 37 by holding capacitors 14 and 28 respectively.

Peak detection voltages are added by an addition circuit 21 to generate a signal VOUT which is free from a DC offset voltage error dependent upon the original transmission data signal. First and second resistances 36 and 38 extract common mode components from the input signal and, and they are subtracted from the signal VOUT to generate a true data output signal VTO free from error.
