Title: Pcm recording and reproducing device
Inventor: AMADA NOBUTAKA
IPC: H04N5/928
Filed: 1985-06-21
Abstract: PURPOSE:To permit digital recording with a home VTR and to prevent the inter- disturbance with a video signal by converting an audio signal to a PCM digital signal and recording and reproducing said signal by frequency multiplexing to the outside of the occupying band of the video signal or between the bands of a low carrier wave FM luminance signal and low range conversion color signal. CONSTITUTION:The video signal is separated by an LPF 10 and BPF 12 to the luminance signal and chromaticity signal which are recorded via an FM modulator 11 and a frequency converter 13 by heads 16a, 16b on a tape. On the other hand, the audio signal is subjected to interleaving by adding a synchronizing signal and correction code thereto in a digital processing circuit 21 aiv an analog-to-digital converter 20 and is then subjected to O-QPSK modulation in such a manner that the recording signal can be recorded between the occopying bands of the low range conversion chromaticity signal and the low carrier wave FM luminance signal in an O-QPSK modulation circuit 22. Such signal is recorded on the video tracks by audio heads 26a, 26b via a BPF 23 and a limiter circuit 24 in precedence to the video record. The signal in the surface layer part is erased by the video signal to be recorded afterward and remains in the deep layer part.

Title: Demodulator for spread spectrum signal
Inventor: FUJITA MASAHIRO
IPC: H04B1/7087
Filed: 1984-06-29
Abstract: PURPOSE:To obtain a conversion PN lock state by controlling an oscillating frequency of a VCO for doppler shift lock so as to be fixed to a prescribed value when an output level of a BPF reaches a prescribed value or below. CONSTITUTION:A CPU8 has a switch means 25 controlled switchingly by an envelope output confirming signal EVH as a control signal DPC to a doppler shift lock VCO10. The means 25 transmits a normal control signal NOR as a control signal DPC when an envelope detection output ENV is a threshold value Lth or over and transmits a forced control signal REF as a control signal DPC because of the absence of an envelope output confirming signal EVH when the detected output ENV is a value Lth or below. The signal REF is selected in advance to a value at which the VCO10 oscillates at a center frequency f0 of a foced frequency range VOCf. Thus, the frequency of the signal PSS is kept within the pass band of a BPF11 when the VCO10 and 15 are transited from the force control state to the normal control state and the doppler shift lock loop follows correctly the frequency of the input signal.

Title: Image formation device
Inventor: SAKATA SEIJI
IPC: H04N1/04
Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To provide an image formation device capable of performing appropriate image formation corresponding to the kind of an original. SOLUTION: When a start key is depressed and the original is present in an ADF(automatic document feeder), a scanner is moved to a first read area (S1-S3). When the ADF starts feeding the original, the scanner reads the original moved in the first read area and then, is moved to a home position (S4-S6). Based on the read data of the scanner, whether the original is color or black and white is judged (S8). As the result of the judgement, at the time of a color original, when the scanner reads a still original in a second read area, a processing for preparing color images is performed (S10, S11 and S12). On the other hand, at the time of a black and white original, when the scanner reads the still original in the second read area, the processing for preparing black and white images is performed (S9, S11 and S12).

IPC: H04L25/49
Filed: 1987-05-29
Abstract: PURPOSE: To perform a self-clocking quick synchronous communication between devices at an optional speed within a wide speed range by using a two-pole pulse of a fixed width and sending a second pulse of an inverse polarity after a first pulse when a next signal is the same value. CONSTITUTION: An waveform 80 indicates NRZ data transmitted from a driver to a controller and it is assumed that the signal of 6 bits for indicating a binary pattern 101100 is transmitted. The respective bits appear only for the bit cell time T and a code Ti indicates the time width of the bit cell of an (i)-th bit. Data for which the signal is encoded are the waveform 82 and it is transmitted to a cable 10. In the case that both of the two adjacent bit cells are '0' or '1,' the additional pulse of the inverse polarity is added to the first one of the two adjacent bit cells. Thus, DC components are not included at all and the waveform 82 is AC transmitted to the cable 10.

IPC: G01V8/10
Filed: 1987-06-01
Abstract: PURPOSE:To detect the accurate edge position of a body to be measured by detecting the edge position of two normal and inverted images obtained by dividing an edge image. CONSTITUTION:Light from a light source 1 is collimated to luminous flux by an illumination lens 2 to illuminate an edge part on the body 3 to be measured. Light from the edge part 3a is split by a half-mirror 5 into pieces of luminous flux A and B and the luminous flux A which is reflected by the mirror 5 is passed through a pentagonal prism 6 and a light quantity adjusting fin 8 to form the normal image of the edge 3a on a linear array sensor 9a. Further, the luminous flux B transmitted through the mirror 5 forms the 180 deg. inverted image of the image of the edge part 3a on a linear array sensor 9b through two mirrors 7. The a sensor 9 detects the edge position from the normal and inverted images, so the accurate edge position can be detected without being affected by variation in the quantity of light of the light surface and the blurring of the edge image.
