Title: Denitration agent, method for manufacturing denitration agent and denitration method
Inventor: ASANO YOSHIHIKO
IPC: B01J20/04
Filed: 1992-10-13
Abstract: PURPOSE:To manufacture a denitration agent which has high NOx removal efficiency and carries it for a long time by allowing an activated charcoal to bear NaHCO3. CONSTITUTION:An activated charcoal is allowed to bear NaHCO3. In addition, the activated charcoal is allowed to bear Na2CO3. Further, the activated charcoal is soaked in an NaHCO3 or Na2CO3 solution, and then is dried to impregnate the charcoal with NaHCO3 or Na2CO3. After that, the denitration agent thus obtained is arranged in a treatment container where NOx gas circulates to obtain a denitration device. Thus the denitration agent demonstrates a high a NOx removal efficiency due to a synergistic effect generated by NaHCO3, Na2CO3 and the activated charcoal.

Title: Advertisement display device
Inventor: KAMIYA KAORU
IPC: G09F15/00
Filed: 1991-09-25
Abstract: PURPOSE:To easily install an advertisement board which sufficiently withstands the strong wind like a typhoon by supporting respective divided display plates so that their right and left parts are independent and their lower parts can swing. CONSTITUTION:The display surface of the advertisement board is laterally divided into the divided display plates 1, which are supported on a support frame 4 so that the right and left upper parts are independent and the lower parts can swing. Further, upper-side support holes and lower-side support holes are bored at the right and left sides of the upper side and lower side of each divided display plate 1, which is replaced by using those support holes.

Title: Method and device for detecting ground fault of dc circuit
Inventor: YAMAZAKI TAKEO
IPC: G01R31/02
Filed: 1994-11-09
Abstract: PURPOSE: To prevent a person from being exposed to danger so as to improve the safety and economy of a DC circuit by periodically switching intermediate potentials having opposite polarities and the same potential difference to each other on the basis of the neutral point of the DC circuit. CONSTITUTION: When a high-potential-side terminal TP and low-potential-side terminal TN are viewed on the basis of the neutral point (potential: E/2) of a DC circuit 2, they form two kinds of intermediate-potential electrodes having opposite polarities and the same potential difference. Then voltages 2E/3 and E/3 are respectively fetched from the terminals TP and TN to a cathode-side line against the voltage E of a DC power source 1, such as the solar battery, etc. Ground-fault currents are detected by periodically switching the two kinds of intermediate potentials to each other by means of a switching means 3. Therefore, even when a ground fault occurs at any part of a circuit containing the power source 1, the ground fault can be surely detected and the polarity of the ground fault can be discriminated from the difference between the detected current values.  In addition, the risk of electrical shocks, etc., can be eliminated and such a ground-fault that results in a fire can be detected. Moreover, the circuit configuration of the DC circuit can be simplified.

Title: Generation and decoding method for frequency division multiplex signal
Inventor: KANEKO KEIICHI
IPC: H04J11/00
Filed: 1995-10-24
Abstract: PROBLEM TO BE SOLVED: To reduce the peak power by controlling the arithmetic method based on the arithmetic result obtained at a prescribed stage of an inverse discrete Fourier transform operation. SOLUTION: An arithmetic part applies the inverse discrete Fourier transforms to the digital information signals which are inputted to plural input terminals. The arithmetic result obtained at a stage right before the final stage of the arithmetic part is divided into the first half parts E0 to E255 and the second half parts H0 to H255 . Then an operation is carried out with the parts E0 to E255 used as they are and the parts H0 to H155 set at zero respectively, so that a 1st arithmetic result F1(t) of the final stage is acquired. At the same time, a 2nd arithmetic result F2 (t) of the final stage is obtained through an operation carried out with the parts E0 to E255 set at zero and the parts H0 to H255 used as they are respectively. The normal final stage result F(t), if defined so, is equal to F1(t)+F2(t).  If the result F(t) includes the peak value higher than a prescribed level, the data string of the result F2(t) is shifted and added to the result F1(t). As a result, the peak value can be reduced.
