Title: Carrier phase reproduction for adaptive equalizer
Inventor: UU EICHI PEIKU
IPC: H04B3/06
Filed: 1992-07-27
Abstract: PURPOSE: To adaptively equalize a data signal without using phase rotation or inverse rotation. CONSTITUTION: A demodulation signal is filtered in an adaptive equalizer 60 and an adaptive filter coefficient is updated at first by using an error signal guided from a first algorithm. When a signal output phase error from the adaptive equalizer reaches a threshold, a carrier lock signal is generated (62 and 78). The adaptive filter coefficient is updated by using the error signal guided from a second algorithm instead of the first algorithm (74). The first algorithm is a self-reproduction equalization algorithm and the second algorithm is a decision direction algorithm. The carrier phase is reproduced without using a phase rotating unit or a phase inverse rotating unit by positioning the adaptive equalizer into a carrier reproduction loop 56.

Title: Temperature control circuit of floor heating device
Inventor: NARUO MASAYUKI
IPC: G05D23/24
Filed: 1982-12-13
Abstract: PURPOSE:To make a circuit safe stopping power supply or hot water supply for a floor heating panel by a method wherein, when a floor or room temperature detecting senser is troubled with disconnection, the disconnection is detected to interrupt the circuit immediately. CONSTITUTION:When a room temperature senser 7 is disconnected, a transistor Tr1 is interrupted since the base current of the transistor Tr1 is deprived of its loop to flow in. Thus the base current of another transistor Tr2 flowing through a resistor R3 and a floor temperature sensor 6 can not flow interrupting the transistor Tr2. Resultantly, the inverse input terminal of a comparator CP2 of a diode D1 is impressed with power supply voltage Vcc-0.7V through another resistor R5 making non inverse input voltage<inverse input voltage as well as output low level not to drive a relay Ry interrupting power supply for a floor heating panel 3. On the other hand, when a floor temperature senser 6 is disconnected, the base current of the transistor Tr2 can not flow to interrupt the transistor Tr2 likewise interrupting power supply for the floor heating panel 3.

Title: Spent nuclear fuel reprocessing method by low temperature and high load purex method
Inventor: TATEMORI KATSUICHI
IPC: G21C19/46
Filed: 1989-08-25
Abstract: PURPOSE:To make possible the separation and recovery of uranium, plutonium and neptunium in a high recovery rate and high purity by using a series of multistage countercurrent solvent extraction processes (tributyl phosphate extractive agent) including a low temperature process. CONSTITUTION:In order to separate uranium and plutonium from each other, the temperature of an extraction system is reduced down to 0-5 deg.C. Next uranium and plutonium can be simply separated without regulation and control of a valence with the use of the effect in which a plutonium extraction division ratio is lowered by increasing a degree of concentration of uranium in an organic solvent and a uranium division ratio is increased. In addition, since plutonium is separated to recover with the use of a low temperature and high load process, uranium and neptunium left thereafter can be separated easily. Actinide elements such as uranium, plutonium, and neptunium in a spent fuel can be simply and safely separated to recover by the temperature reduction of an extraction process and the increase of a degree of uranium concentration in the organic solvent.

Abstract: PURPOSE:To lessen the degrading of battery capacity during aging as well as the period of no use after shipment by piercing an air hole whose diameter is small as compared with the thickness of the bottom plane of a battery case by using a laser beam. CONSTITUTION:A circular recessed part 9 is formed in the bottom plane of a case 1 and a battery is prepared by using the case and after aging, laser beam is radiated to the recessed part 9 of the case of the battery from the outside of the case to form an air hole.
