Title: Spread spectrum communication system
Inventor: YAMAMURA HIDEYA
IPC: H04B1/707
Filed: 1997-09-16
Abstract: PROBLEM TO BE SOLVED: To provide a system enabling number of signal points to increase by decreasing an error rate in the case of data transmission in spread spectrum communication. SOLUTION: A convolution coding part 1 applies error correction coding processing to transmitted data to produce transmission data. A mapping part 2 arranges the transmission data to signal points corresponding to data values. A PN series generating part 3 generates a PN series based on a part of the transmission data. A spread part 4 multiplies a PN series generated by the PN series generating part 3 with an output of the mapping part 2 to make the transmission signal spread. An inverse spread part 5 detects the PN series used at a transmitter side to apply inverse spread to a reception signal by using the detected PN series. A re-mapping part 6 obtains the transmission data from the signal points where the reception signal is arranged. A supplement information processing part 7 obtains supplement information based on the detected PN series.  A Viterbi decoding part 8 reproduces transmitted data from the transmission data while utilizing the supplement information.

Title: Composite thin film integrated circuit
Inventor: YONEHARA HIROYUKI
IPC: H01L27/13
Filed: 1987-10-05
Abstract: PURPOSE:To prevent a wiring from touching a conductive pattern by a method wherein a composite thin film IC provided with a condenser is provided, where a Ti thin film is provided onto the top of an upper electrode and its peripheral section is covered with a solder wetting preventive film. CONSTITUTION:A condenser 1 is composed of a lower electrode 3, a Ta2O5 dielectric layer 4 formed thereon, and a NiCr-Au-Ti upper electrode 7 formed on thermoresistant substrate 2. Solder does not adhere to Ti but an Au thin layer excellent in a solder wetting property is exposed at the side face, wherefore the peripheral section of the upper electrode 7 is covered with a solder wetting preventive film 6. Ti is excellent is comparatibility with the solder wetting preventive film 6, so that an excellent adhesion between them can be obtained. Moreover, the solder wetting preventive film 6 is coated only on the peripheral section of the upper electrode 7, wherefore the stress induced by the difference between them in a thermal expansion coefficient can be decreased in its effect on them.

Title: Transponder
Inventor: GOKAN AKIRA
IPC: H01Q13/18
Filed: 1984-11-28
Abstract: PURPOSE:To set a transponder at any place by providing the resonance antenna element of a size determined by the frequency of a response on an earth conductor across a dielectric to smaller area than that of the earth conductor. CONSTITUTION:The 1st resonance antenna 3, the 2nd resonance antenna 4, a diode 5, etc., are provided. When a transmit radio wave f1 from a transmitter arrives, the radio wave is hardly absorbed by the antenna 3 and radiated at a frequency nf1 which is an integer multiple to the contrary because of the nonstraightness of the diode 5, thereby making a response to a question radio wave. The antenna 4 is the same as to this operation and a response is made at nf2. Thus, the resonance antennas are formed of microstrips, so a secure response to the question radio wave is made wherever a transponder is installed and the installation place is hardly limited.

Title: Printer for rewrite print card
Inventor: OKUDA YUKITERU
IPC: B42D15/10
Filed: 1999-09-06
Abstract: PROBLEM TO BE SOLVED: To prevent uneven erasure of a visible image by making heat dissipation constant for a heating bar in the direction of recording width and setting the temperature of a heating element so that a visible image recording part just reaches the temperature of transparency. SOLUTION: A heat dissipation plate 4 of aluminum exhibiting excellent heat dissipation effect is attached to the front face of a heating for 1. It has elliptical shape elongated in the direction of recording width and the atmospheric contact part thereof is large in the center but small at the opposite end parts. Since the heat dissipation effect is high in the center but low at the opposite end parts, heat is dissipated more at opposite end parts in the direction of recording width of the heating bar 1 than in the center thereof. But since a heat dissipation plate 4 dissipates heat more in the center that at the opposite end parts, total heat dissipation becomes constant and uneven temperature can be eliminated on the heat face of the heating bar 1 in the direction of recording width.  When a visible image recording section sets the temperature of a heating element 1a just at the temperature of transparency when a rewrite print card is heated while being carried under such heat dissipation conditions, it can be heated at an appropriate temperature uniformly and uneven erasure can be prevented.

A subtracter 31 inputs a set value for the treatment liquid outlet temperature and the measured value of the treatment liquid outlet temperature, and outputs the difference. An integrator 32 inputs the output of the subtracter 31, and outputs the time integration value. A first multiplier 33 multiplies the output of the integrator 32 by integration gain (f). A second multiplier 34 multiplies the output condition vector estimated value X(t) of the observer 30 by condition feed back gain F. An adder 35 adds the output of the multiplier 33 and the output of the multiplier 34, and the opening degree of the control valve 24 is determined in response to this output.
