Title: Delay detection demodulator
Inventor: IGATA YUJI
IPC: H04L27/22
Filed: 1992-11-10
Abstract: PURPOSE:To suppress deterioration of an eye aperture rate of a demodulation signal due to a frequency deviation of a carrier by forming the demodulator with an A/D converter, N-sets of delay devices whose delay time differs from each other, N-sets of detectors, N-sets of counters and a discrimination section. CONSTITUTION:A biphase modulation signal is inputted from an input terminal 101, converted into a digital signal at an A/D converter 103, detected by delay devices 111-113 and XDRs 121-123 and outputted to counters 131-133. A discrimination section 141 selects an output of the detector in which the count is minimized for a preamble period and the result is outputted to a low pass filter 151. Even when a frequency deviation is in existence in the carrier, the delay device with a most proper delay among prepared delay devices is used to detect an input signal depending on the quantity.

Title: Decoding method and its device
Inventor: YASUDA MAKOTO
IPC: H04N19/44
Filed: 1997-10-31
Abstract: PROBLEM TO BE SOLVED: To generate an error code immediately before first hierarchy information and securely start decoding at every code string by inserting a second code string so that one of the codes containing a part of a first code string does not correspond to a prescribed code table used for the decoding of the code string. SOLUTION: A bit stream fraction is analyzed and dummy data 10 is inserted immediately before a header following a prescribed picture, namely, an I picture as a second code string in a bit stream. The dummy data 10 is the code where plural pieces of '0' data are arranged, for example. Then, plural pieces of '0' data continue between the header of the I picture and an elementary bit stream which is immediately before by adding dummy data 10. The error code is generated immediately before the picture header and encoding can be started at every I picture for the decoding means by inserting dummy data 10. Thus, the occurrence of the considerable disturbance of the picture can be prevented.

Title: Data transfer method
Inventor: NAGATOMO HIRONORI
IPC: G06F15/177
Filed: 1986-12-17
Abstract: PURPOSE:To contrive the speed up of the data transfer speed by incorporating information for the synchronization of each processing system at transmission and reception side into each unit data frame in the transfer data. CONSTITUTION:The unit data frame is constituted by one byte and synchronizing information is written to the most significant bit b7 and the remaining 7-bit b6-b0 are used as the unit transfer data area. In this case, the write side (sender side) writes the 8-bit unit data frame being the addition of the most significant bit b7 of '1' to the low-order 7-bit unit transfer data to the common memory 3 directly. The read side (reception side) accesses directly the common memory 3 to read the 8-bit unit data frame to confirm that the most significant bit b7 is at '1', that is, the data is written newly, thereby fetching the unit transfer data of low order bits b6-b0. Thus, one access to the common memory is enough for each processing system at reception and transmission side to attain the speedup of data transfer.

Abstract: PURPOSE:To allow the distinct discrimination of the formed images and circumference of even the projector system of a front type and to improve audio visual environment by projecting the intrinsic images and the light image to form a frame image enclosing the circumference of the intrinsic images on a screen. CONSTITUTION:Signals of R (red) images, G (green) images and B (blue) images are respectively inputted to projecting tubes 11 to 13 and while the projecting light rays of the corresponding R, G, B colors are scanned perpendicularly by a vertical synchronizing signal V and a horizontal synchronizing signal H, the light rays are scanned horizontally and the images of the respective colors R, G, B are thereby synthesized on the surface of the reflection type screen 2. The color images are thus formed on the surface of the reflection type screen 2 and are reflected.

IPC: H04B10/61
Filed: 1993-12-01
Abstract: PURPOSE:To enable data transmission stabilized for both a short distance and a long distance by performing switching to either direct detection or coherent detection corresponding to the transmission distance. CONSTITUTION:Signal light made incident or a reception part is made incident through an optical synthesizer 106 or an avalanche photodiode PD 109. The DC component of an optical current excited by the PD 109 is inputted to a power comparator 110 and when power is less than a prescribed value, a signal '1' is outputted from the comparator 110 but when power is more than the prescribed value, a signal '0' is outputted. When the signal '1' is outputted, a local oscillating light source LD 108 is oscillated and turned to a coherent detection mode, and the output of the PD 109 is passed through a narrow band filter 112 and demodulated by a demodulator 114. On the other hand, when the signal '0' is outputted, the LD 108 is not oscillated but turned to a direct detection mode, and the output is passed through a wide band filter 113 and demodulated by a demodulator 126. Thus, data more than 1MBit/s can be transmitted up to several tens (m).

Title: Color liquid crystal display element
Inventor: AOKI HISASHI
IPC: G02F1/133
Filed: 1995-10-27
Abstract: PROBLEM TO BE SOLVED: To provide a double refraction control type element capable of displaying a bright image. SOLUTION: Pixel electrodes 15 and TFTs 14 are arranged in matrix shape on a TFT substrate 11. A common electrode 17 and a blackmask BM are formed at a counter substrate 12 side. The blackmask BM is formed of a film having frequency dependency in light transmitivity and coloring transmitted light to a prescribed color. The TFT substrate 11 and the counter substrate 12 are aligned and are stuck together. Since the blackmask BM transmits light, numerical aperture is not reduced too much even if misregistration is generated and the display region is covered with the blackmask BM. Further, since transmitivity of the blackmask BM has wavelength dependency, only light equivalent to a display noise which causes decrease of displaying color purity can be selectively removed. In succession, a liquid crystal 13 is poured.  Further, a pair of polarizing plates 23, 24 are arranged so that desired color is developed corresponding to the change of orientation state of the liquid crystal 13.
