Title: Demodulator for quadrature frequency division multiplex system
Inventor: KAWABE TAKESHI
IPC: H04J11/00
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To shorten the pull-in time of a carrier frequency by demodulating an in-phase signal and a quadrature signal from a selected quadrature modulation wave, converting a digital signal, multiplying a delayed signal by an original signal, adding the output of a multiplier by prescribed time, controlling a gain, generating the timing of a valid symbol and executing discrete Fourier transformation. SOLUTION: A tuner 10 frequency-converts a desired frequency band into an intermediate frequency band. The frequency-converted signal is orthogonally demodulated by a quadrature demodulator 11 and I and Q signals are reproduced. A ground interval removal circuit 14 takes out only the valid symbol part of the digitized signals of the I and Q signals and it is transferred to an FFT processing part 15. A QAM demodulation circuit 17 demodulates data of the respective carriers and an error correction circuit 18 corrects errors and outputs the signal as demodulation data. The guard interval removal circuit 14 separates only the valid symbol with a synchronizing signal 6 from a synchronism processing circuit 22 as a reference and transfers it to the FET processing part 15.

Title: Voltage-controlled oscillating circuit
Inventor: FUKUI HIROKAZU
IPC: H03K3/02
Filed: 1981-08-17
Abstract: PURPOSE:To decrease the number of elements and to reduce the size by detecting the voltage of a capacitor, charged according to the level of an input signal, through a Schmitt circuit composed of MOS transistors (TR), and thus discharging the capacitor. CONSTITUTION:When an input signal VIN is applied to an input terminal IN, a gate voltage which corresponds to the signal VIN is applied to gates of MOSTRs M5 and M6, so a capacitor C is integrated by a current which corresponds to the signal VIN. A Schmitt circuit 23 consists of MOSTRs M11-M15. When the potential of the capacitor C is low, the M11 is turned off and an output OUT  has a high level. When the potential of the capacitor C is higher than the output VB of a voltage switching circuit 232, the M11 turns on. Then, the output OUT has a high level and the capacitor C is discharged through the M8 and  M6 to hold the source voltage of the M11 at the earth potential because the  M13 turns on, thereby turning on the M11 securely.

Title: Method for obtaining superconductive wire
Inventor: YAMANO MASARU
IPC: B28B1/00
Filed: 1987-05-25
Abstract: PURPOSE:To manufacture wires of superconductive material of oxide type by coating the superconductive material of oxide type continuously in the longitudinal direction of a tape-shaped copper foil, irradiating laser beam continuously in the longitudinal direction as the baking process, and rolling the copper foil to press to its surface. CONSTITUTION:Superconductive material of oxide type is continuously coated on a tape-shaped copper foil 1 in its longitudinal direction, and laser beam 8 is irradiated to this coated superconductive material in its longitudinal direction to cause continuous fusion associate with a baking process, and then another copper foil 10 is rolled fast onto the surface of this baked superconductive material. Because the superconductive material is coated directly on the first named copper foil 1, the filming speed is large, that together with use of laser beam 8 as means to bake the superconductive material, enables local heating to provide heating into wires without giving influence upon the copper foil 1. Besides this, use of rolling method should further enhance the mass productivity. Thereby superconductive material of oxide type can be easily turned into wires.

IPC: H01L21/208
Filed: 1979-10-04
Abstract: PURPOSE:To permit a large number of substrates to be produced at a time by providing upper and lower slide plate each slidably penetrating a liquid growth apparatus body, and a mounting portion on which a plurality of substrates are placed in parallel in the space inside the apparatus body between the slide plates. CONSTITUTION:A plurality of substrates 3 are placed in parallel on a substrate holder 13 in a growth chamber. Sliders 7 and 8 are penetrated through a boat body, and a liquid chamber 10 is filled with a liquid. Then, this liquid growth apparatus is heated to a given temperature. A control rod 14 is pulled in the direction of an arrow so that slits 7a are right below the liquid chamber 10 in order to allow the liquid to drop into a growth chamber 11 and to contact with the substrates 3. When the liquid growth is finished, the control rod 14 is moreover pulled in the arrow direction. This causes a hook-shaped end 7c of the slider 7 to hook and move the slider 8, so that a hole 8a is right below the growth chamber 11. During said operation, all of the liquid in the growth chamber 11 drop in a receiving chamber 12. Thus, a large number of substrates can be produced at a time.

Title: Phase modulated corona electric charger
Inventor: JOHN W MEI
IPC: H01T19/00
Filed: 1997-05-19
Abstract: PROBLEM TO BE SOLVED: To improve charge efficiency and uniformity by having a phase difference between a second AC voltage signal and a first AC voltage signal. SOLUTION: A first corona power source 50 generates a first high-pressure AC signal to be applied to a corona wire 12B. A second corona power source 51 generates a second high-pressure AC signal to be applied to corona wires 12A and 12C. The second AC signal is substantially identical to the first AC signal in voltage and frequency except that it is shifted to the first AC signal by 180 degrees. Hence, as the wires 12A and 12C reach the maximum potential in one cycle, the wire 12B reaches the minimum potential. The wire 12B acts as an electrode for temporarily increasing discharge due to the wires 12A and 12C. As a result, a net current to be transmitted by a grid 14 is increased, an impedance of a charger 10 decreases, and significant improvement in charge uniformity is found.

Title: Method for welding thick material with high speed laser beam
Inventor: SAITO MICHIO
IPC: B23K26/06
Filed: 1987-05-26
Abstract: PURPOSE:To elevate the efficiency of laser welding by projecting, for seam welding, a plurality of laser beams different in focal distance received with condenser lenses different in the radius of surface curvature at the central part and on the peripheral part. CONSTITUTION:The condenser lenses for laser welding comprise two redii of curvature and the radius of curvature (ra) on the central curved surface is larger than the radius of curvature (rb) on the periphery. The radius r1 at the central part and the radius r2 on the peripheral part of the lens, are made so that a relation, r1 0.7r2 is established to drive energy equally. When laser is condensed by using these lenses, the focal planes at the central part and on the peripheral part, Sa, Sb are deviated in the vertical direction and the amount of deviation is made nearly half the thickness (t). Accordingly, since the half of the energy is not reflected on a hole but penetrated as far as the central part of the thickness, fruitless energy to be consumed for melting the wall is reduced and the energy equivalent to that amount is used fruitfully to melt the thickness.

Filed: 1990-05-18
Abstract: PURPOSE:To freely set a final gear reduction ratio or the like comparatively by setting a reduction ratio between a final output stage gear and its preceding stage gear to one over an integral number. CONSTITUTION:A reduction ratio between a final output stage gear 1e and its preceding stage gear 1d is set to one over an integral number. Moreover, a ratio of number of teeth of other gears 1a, 1b, 1c is not especially set to an integral number ratio. Even when mis-centering error or the like takes place in any of 1st-3rd gears 1a-1c which are intermediate gears, since only the gear reduction ratio of gears after a gear having the eccentricity is effective to a ball screw 3, the error is reduced by the reduction ratio and almost no hindrance is caused to the feeding accuracy of an original. Thus, the final gear reduction ratio of a reduction gear train 1 is comparatively freely set.
