Title: Ofdm signal synchronization device
Inventor: MATSUMOTO YOICHI
IPC: H04L27/00
Filed: 1998-04-22
Abstract: PROBLEM TO BE SOLVED: To reduce frequency estimation errors by detecting the phase change amount of orthogonal frequency multiplex signals during a repetition time based on the orthogonal frequency multiplex signals and delay signals for which they are delayed for the repetition time, obtaining a weighted moving average based on the phase change amount and estimating the frequency error of the orthogonal frequency multiplex signals based on the weighted moving average. SOLUTION: A delay circuit 10 outputs digital signals SG2 delayed for prescribed time to the digital signals SG1 and a phase rotation angle detection circuit 20 outputs the change amount of a phase between the digital signals SG1 and SG2 as the digital signals SG3. A weighted moving average circuit 40 calculates the weighted moving average of the digital signals SG3 and outputs it as the digital signals SG4. By using weighting, the digital signals SG4 are hardly affected by delay waves and are highly reliable. A frequency error estimation circuit 50 generates the digital signals SG5 for indicating the frequency error based on the digital signals SG4.

Title: Production of water-repelling clear coat
Inventor: NAKAGAWA TORU
IPC: C09K3/18
Filed: 1996-05-07
Abstract: PROBLEM TO BE SOLVED: To form a water-repelling clear coat by using a coating liquid easily applicable in air, resistant to the deterioration of the water-repelling coating liquid with time and capable of easily forming a uniform coating layer on a substrate by restricting the surface tension of a water-repelling coating solution containing a specific silane compound within a specific range. SOLUTION: This process for producing a water-repelling clear coat comprises a step to immerse a substrate in a water-repelling coating solution of a compound having fluorocarbon chain and a methoxysilyl group or a fluorocarbon chain and an ethoxysilyl group, a step to take the substrate out of the water-repelling coating solution and evaporate the solvent and a step to hydrolyze and polymerize the compound to form a water-repelling coat on the substrite. In the above process, the surface tension of the water-repelling coating solution is adjusted to be lower than the surface energy of the substrate in the step to immerse the substrate into the water-repelling coating solution. The surface tension of the water-repelling coating solution is maintained to <=18dyne/cm.

Abstract: PURPOSE:To allow quick attainment of the specified temp., equip a high rate of extreme infrared radiation and excellent anti-impact property, and provide possibility of processing, by forming a dense film of metal oxides in close contact with the surface of metal material. CONSTITUTION:A dense film of metal oxides is formed in close contact with the surface of a metal material, wherein the film is in the form of pure substance of oxides with a high rate of extreme infrared radiation such as TiO2, Fe2O3, Al2O3, SiO2, or their admixture or composite layered body. The film is dense without hole or any other defect, and its thickness shall preferably be 0.5-5mum, as too thin film does not give satisfactory high rate of extreme infrared radiation while too thick film is likely to be crack initiated and exfoliated at the time of processing. The metal material to constitute substrate for the film shall optimally be stainless steel which excels in anti-corrosiveness and has an appropriate strength. This prevents damage to be caused by impacts, allowing attainment of specified temp. in a short time, and provides a high rate of extreme infrared radiation and excellent heating effect.

Title: Magnetic bubble memory device
Inventor: OOTAKE ITARU
IPC: G11C11/14
Filed: 1982-06-30
Abstract: PURPOSE:To widen temperature range in which stable operation is obtained, by filling resin having a thermal expansion coefficient larger than that of molding resin in the cavity between two coils intersecting at right angles set in a base plate on which a magnetic bubble chip is mounted. CONSTITUTION:A Y-coil 13 and an X-coil 14 are fixed into a ceramic base plate 12 on which a magnetic bubble chip 11 is mounted. Silicone resin 15 is injected into a cavity between the base plate 12 and coils 13, 14 and heat cured at about 150 deg.C. All of these are molded with epoxy resin 16. Before hardening of the resin 16, a homogenizer and a bias magnet are attached on both sides of the base plate 12. Since silicone resin having a large thermal expansion coefficient is packed between the base plate and coils 13, 14, the thickness of coils changes reversibly in relation to temperature, and the driving magnetic field decreases with rise of temperature. Thus, temperature range of stable operation is widened.

Filed: 1983-06-22
Abstract: PURPOSE:To obtain stable operation by preventing air from mixing, by a method wherein the nozzle part is magnetized and sealed with magnetic ink in non-flight of ink. CONSTITUTION:When electric power is applied to electromagnets 18a and 18b, nozzles 19a and 19b are magnetized and magnetic ink 22 is strongly attracted to the edge part having high density of magnetic magnetic force 26. When driving signal 21 is applied to piezo-diaphragm 13 under the state where nozzle 19 is not magnetized, because keeping force is not operated at the opening part of nozzle 19, magnetic ink 23 is discharged from meniscus 20. When the driving signal 21 applied to piezo-diaphragm 13 is turned off and magnetic ink drop 24 is separated from nozzle 19, the nozzle 19 is magnetized with electromagnet 18. Then, the opening part of nozzle 19 is again operated with the force keeping magnetic ink 23 and air is not mixed even though rapid pressure decrease of inner ink chamber 15 is generated. Therefore, the driving signal of piezo-diaphragm 13 can steadily operate even though the falling time of voltage is very rapid.
