Abstract: PURPOSE:To obtain a formed concrete article while suppressing efflorescence by pouring a ready-mixed concrete into a mold, curing in closed state, demolding the product and reacting the efflorescent component with a reaction liquid or carbon dioxide gas. CONSTITUTION:A concrete inner mold 2 surface-impregnated with a releasing agent is placed on a bottom mold 1, a concrete outer mold 4 fixed with a plastic outer mold 3 produced by transferring the outer surface of a rock to a urethane resin (rubber) is placed on the mold 1, a ready-mixed concrete 6 is poured into the mold through a pouring hole 5 and the concrete is demolded after curing to obtain a bottom-opened shell having an opening at the top. When the curing is carried out after closing the pouring hole 5 in this process, water is consumed by the hydration reaction to dry the face contacting with the plastic outer mold 3 and, accordingly, the generation of the primary efflorescence is suppressed to reduce the water-absorptivity. The demolded concrete having suppressed primary efflorescence is impregnated with a reaction liquid in such a manner not to retain the liquid on the surface of the mortar, etc., or the surface of the concrete is heated at a high temperature and the reaction of the efflorescent component with the reaction liquid or carbon dioxide gas takes place to suppress the secondary efflorescence.

Title: Interference removing method
Inventor: KUBOTA KEIICHI
IPC: H04B1/10
Filed: 1983-04-14
Abstract: PURPOSE:To remove effectively an interference wave mixed into an input frequency modulated wave by differentiating an amplitude modulated component detected in the input frequency modulated wave, and adjusting and subtracting a 90 deg. phase-shifted signal from a demodulation output signal. CONSTITUTION:A receive input frequency modulated FM wave disturbed by ratio interference is inputted to a limiter 1 and an envelop detector 3, and the wave is led to an FM demodulator 2 after its AM component is limited by the limiter 1 and then demodulated. The detector 3 detects the AM component of the input FM wave and the AM component is differentiated by the differentiating circuit 4, whose output is shifted in phase by 90 deg. through a 90 deg. phase shifting circuit 5 to generate a component similar to the disturbing component generated in the FM wave owing to the interference. The component corresponding to the disturbing wave is led to a gain adjusting device 6 to be adjusted in level properly and then led to a subtracter 7, which subtracts the output of the adjusting device 6 from the output signal of a demodulator 2. Consequently, the FM demodulation output signal after the interference component being canceled and removed is obtained.
