Title: Decision feedback equalizer
Inventor: YAMAGUCHI MASARU
IPC: H04B3/06
Filed: 1986-04-14
Abstract: PURPOSE:To improve the matching of a distortion equalizing signal to the distortion part of an input part and to improve equalization characteristics by providing a waveform converting circuit which converts the distortion part equalized waveform of the output signal of an equalized waveform generator stepwise from a rectangular wave and supplying this staircase wave to a low-pass filter and supplying the distortion equalizing signal to a subtracter. CONSTITUTION:A signal (a) which has a signal part 20 and a distortion part 21 is inputted to an input terminal 1. The subtracter 4 calculates the difference between the input and output of a data decision circuit 3 and then generates an error signal. An equalized waveform generator 5 refers to the output of the data decision circuit 3 and the output of an error signal generating circuit 4 to generates the rectangular waveform (b) which is the digital equalized waveform. A waveform converting circuit 8 performs conversion so that the output waveform of a digital-analog converting circuit 6 is the staircase wave (c). The low-pass filter 7 receives the output of the digital-analog converter 6 and outputs a distortion equalizing signal (d). The cutoff frequency of the low-pass filter 7 can be set high because the input is already the staircase wave, and a delay time is sufficiently short, so the waveform itself can be matched sufficiently with the position equalized distortion waveform with a peak value, so that equalization is performed completely by a subtracter 2.

Title: Reproducing method for magneto-optical recording medium
Inventor: KAWANO TOSHIFUMI
IPC: G11B11/105
Filed: 1993-04-12
Abstract: PURPOSE:To obtain a method by which a reproduction is performed with a smaller cross talk by using a FAD system simplifying the manufacture of a medium and obviating an initialization magnet. CONSTITUTION:The reproduction of signals is performed by using a magneto- optical recording medium in which the inter-code interference of signals at the time of reproduction is much more reduced than a normal reproduction by erasing temporarily the recording in a part when a medium temperature is raised up to a temperature higher than a specified temp. by a reproducing light and by starting again the recording when the temp. is lowered. In such a case, a track having information is reproduced with the reproducing light by irradiating, with an auxilliary light, a track on one side or tracks on both sides being adjacent to the track having information to be reproduced while erasing signals on the adjacent tracks with its heating.

Title: Apparatus and method for surveillance of admixture in oil
Inventor: DOI MOTOTATSU
IPC: G01N1/10
Filed: 1990-04-02
Abstract: PURPOSE:To enable continuous and automatic surveillance for a long period of years by making oil of measuring object flow continuously in a pipe and trap admixtures in the oil on the pipe wall with magnetic force. CONSTITUTION:The lubricating oil 11 of measuring object is taken out of a lubricating tank 1 and is taken in a transparent pipe 22 around which a magnetic field is formed by a bottom magnetic 21 in a ferrography device 2, and admixtures floating in the lubricating oil 11 are trapped on the pipe wall by the magnetic force. This transparent pipe 22 is illuminated by a lump 27 below the magnet 21 and the transmissivity reduces when the admixtures are trapped on the pipe wall. Then a photo detector 24 converts it into an electric signal and outputs the signal to record in a data processor 3 continuously all the time. And if the relation between transmissivity and admixture amount deviates from the proportionality due to the admixtures, then the magnet 21 is lowered automatically by a linear head motor 26 and accordingly a gear pump 23 exhausts the admixtures with a high speed operation. Thereafter, the motor 26 returns to the original position and the pump 23 shifts to a small flow operation.

Title: Cut sheet
Inventor: SHIMOMURA YOSHINOBU
IPC: G03G15/00
Filed: 1993-03-22
Abstract: PURPOSE:To surely prevent the occurrence of duplicate feeding in feeding papers by setting the warpage height of the end of a cut sheet fed by a copying machine, etc., to a specific value. CONSTITUTION:In a roller separation transfer material paper feeding method, a transfer paper 2 on the utmost upper part in a cassette 3 is delivered by the rotation of a pickup roller 1, and the delivery is regulated by a claw 4 provided on the front end of the cassette 3 to rise the front part of the transfer paper 2. A lower side transfer paper 5 is separated by this rise, and then the end surface of the transfer paper 2 is separated from the claw 4 due to the strength of the toughness of the transfer paper 2 to be delivered toward the front. In this case, when an upward warpage exists on the end surface of the transfer paper, the transfer paper tends to be overlappedly fed, therefore for eliminating this overlap-feeding occurrence, the height of the warpage on the end of the transfer paper 2 is set to 0.5mm or less. The friction factor between a pickup roller 1 and the transfer paper 2 is set to 2.0 or less.

Title: Light transmitter, light transmitting equipment and light modulator
Inventor: KITAJIMA SHIGEKI
IPC: H04B10/2537
Filed: 1992-04-07
Abstract: PURPOSE:To avoid attenuation of a signal caused by induction Brillouin scattering while suppressing variation of intensity by constituting it with a light source for transmitting, an intensity modulator for a transmitted signal and a phase modulator to spread spectrum. CONSTITUTION:After a light signal from a light source 1 for transmitting passes through an intensity modulator 2 for a transmitted signal and a phase modulator 3, it is outputted. A signal from a transmitted signal generator 4 is inputted to the intensity modulator 2 for a transmitted signal, and a signal from a signal generator 5 for spectrum spread is inputted to the phase modulator 3. A light signal from the light source 1 for transmitting becomes a intensity-modulated light signal according to a signal from the transmitted signal generator 4 in the intensity modulator 2 for transmitted signal. Also, when it passes through the phase modulator 3, it is phase-modulated according to a signal from the spectrum spread signal generator 5, and spectrum of the light signal is spread. Consequently, the outputted light signal stops to generate induction Billouin scattering.

Title: Method for creating laminated structure data and recording medium
Inventor: TERAMAE SHOICHI
IPC: H05K3/00
Filed: 1997-04-03
Abstract: PROBLEM TO BE SOLVED: To easily obtain data which represents the structure of a laminated structure even when the structure of a laminated structure is complicated. SOLUTION: When a computer analyzes a laminated structure (e.g. a structure consisting of sheet materials 40A to 40C) which consists of plural laminated sheet materials, it fetches the coordinate value (e.g. a coordinate value shown in a diagram (A)) of a square part that represents the distribution range of each material, separately extracts an X coordinate value and a Y coordinate value from the fetched coordinate value, and calculates the coordinate of a dot from the combination of the extracted X and Y coordinate values (e.g. a coordinate value shown in a diagram (B)).  Next, it divides the laminated structure into plural areas (four areas in the diagram (B)) whose layered structure are mutually different through the dot coordinate, compares each area with the coordinate value of a square part of each sheet material and decides whether each area exists within the distribution range of each sheet material or not. It creates data that represents the layer structure of each area of the laminated structure from a decision result and the lamination sequence of each member.

Abstract: PURPOSE:To eliminate the generation and influence of antielectric fields at the time of driving a ferroelectric liquid crystal and to improve performance by providing the respective inner surfaces of a pair of substrates facing each other with electrodes subjected to a rubbing treatment. CONSTITUTION:The electrodes 122, 123 on insulating substrates 120, 121 are subjected to the direct rubbing treatment and a smetic liquid crystal which passes through a nematic phase is held between these substrates. In this time, the liquid crystal of the phase system passing through the nematic phase having good orientability next to the isotropic phase in a high-temp. part is required to be selected. Namely, the liquid crystal passing through the nematic phase in which the molecular major axes are unified in the axial direction of orientation and which does not form a laminar structure directly from the isotropic phase is more preferable. Then, the good orientation state is obtd. if the electrodes are subjected to the direct rubbing treatment without using oriented films. The liquid crystal electrooptical device having good characteristics without being affected by the antielectric fields is produced.

Abstract: PURPOSE:To enable the measurement of the length of a moving object in a non-contact manner, by applying two laser beams to the moving object and by detecting Doppler signals of reflected beams therefrom. CONSTITUTION:A laser beam emitted from a laser unit 7 is split in two by a beam splitter 8, and applied in intersection onto a moving object 1 through transmission optical systems 10a and 10b. Then the wavelength of scattered light from the object 1 bringing forth positive and negative Doppler shifts in accordance with a speed V of the object 1. This scattered light is received by a reception optical system 11 and led to a photodetector 12 to be transduced into an electric signal. There is an alternating signal of a Doppler frequency in this signal. This Doppler signal is amplified 13 and improved in S/W by a frequency tracking unit 14. Then a Doppler frequency proportional to the speed V can be detected as a pulse signal. This Doppler frequency is set in an arbitrary frequency division ratio by a setting switch 16 and subjected to frequency division 15. Then a pulse outputted from a frequency divider 15 turns to be a length measurement pulse outputting a unit length per one pulse. By counting 4 this pulse, the length of the object 1 can be measured.
