Title: High frequency attenuation circuit
Inventor: HATANAKA HIROSHI
IPC: H03H7/25
Filed: 1986-04-08
Abstract: PURPOSE:To obtain a excellent attenuation characteristic over a broad band by forming two pin diodes and the 1st-4th current limit resistors and applying a positive bias voltage to a connecting point between the 1st and 3rd current limit resistors. CONSTITUTION:The pin diodes Dl, D2 and the current limit resistors R1-R4 form a bridge circuit and a positive bias voltage is fed to a terminal T3. When Rl/R2=R3/R4, R1<R3=R4, a resistance and a bias voltage are set to bring the internal high frequency resistance of the diode D1 to be a required minimum value, then the internal high frequency resistor of the diode D2 reaches the maximum value and the value between the terminals T1 and T2 shows a low attenuation region to a high frequency signal. In changing the resistance of a resistor R2 up to the highest value, the internal high frequency resistance of the diode D1 is a maximum value and the internal high fre quency resistance of the diode D2 is a minimum value, then the high frequency signal fed to the terminal T1 is blocked by the diode D1, the signal is bypassed by a capacitor C5 at the side of the diode D2 to form the attenuation region with respect to the high frequency signal. Since the circuit does not include an element having a frequency characteristic, the excellent attenuation characteristic over a wide band is obtained.

Title: Method for purifying water in closed water area
Inventor: ITO HAJIME
IPC: C02F1/52
Filed: 1989-03-31
Abstract: PURPOSE:To remove sludge and to obtain water appropriate for the living of organisms by separating sludge from water by settling, returning the supernatant water to the closed water area, flocculating the sludge, dehydrating the flocculated sludge, returning the desorbed water to a settling stage to remove the contaminant, agitating and aerating the water in the closed water area. CONSTITUTION:The desorbed water obtained from the dehydration stage is supplied to a flocculating and concentrating tank 4 to efficiently separate sludge by settling. Since a flocculent is still remains in the desorbed water even in a small amt., the flocculation of sludge is promoted. The supernatant water freed from solid matter is returned to the closed water area. An aerator is set in the closed water area to purify water. The precipitation of sludge in water is promoted by the flocculent remaining in the desorbed water. The water is made harmless by the reaction of the residual components, and water purification is promoted by the combination of the contaminant removal and aeration.

Title: Method for joining membrane of low temperature tank
Inventor: KAIHARA SHOICHIRO
IPC: B23K9/00
Filed: 1992-03-04
Abstract: PURPOSE:To reduce the generation rate of defects in normal welding and to allow tacking work performed by general workers. CONSTITUTION:In the method for joining the membrane of a low temp. tank in which the outer edges of the membranes 1, 2 to be joined are laid one on the top of the other for welding, after the tack adhesion of the overlaid part 1b, 2b of the membranes 1, 2 by means of an adhesive or an adhesive tape 5, the fillet part 3 of the membrane 1 is normally welded. Since a partial build-up part as in the case of the conventional tack welding is not produced, a sound normal welding is possible, and the generation rate of the defects in the normal welding is reduced to a greater extent than before. Moreover, as welding is not required in the tacking work, general workers can carry out the tacking work instead.
