Title: Ac etching method for aluminum foil for electrolytic capacitor
Inventor: TAMAOKI MITSUHIRO
IPC: H01G9/04
Filed: 1992-09-18
Abstract: PURPOSE:To obtain a stable high electrostatic capacity through real-time detection of etching situation by continuously measuring time at peak value from a tank voltage waveform after the rise of tank current in anode cycle and thereafter by detecting the degree of etching from the changes in the measured values. CONSTITUTION:A curve V-Q showing the relation between electrostatic capacity V and the amount of current applied Q becomes maximum at the amount of current applied Qc and, at this point, a curve tau-Q showing the relation between peak time tau and the amount of current applied Q tends to suddenly increase. Since the optimum etching for obtaining the maximum electrostatic capacity has been performed at the time when the amount of current applied is Qc, an etched foil having the maximum electrostatic capacity can be obtained if electrolytic etching is stopped at the point where the variation in the amount of current applied of the peak time tau increases suddenly, that is, the point where the value of differential value dtau/dQ increases suddenly. Also, any change in the etching situation can be detected by continuously measuring the peak time tau from the tank voltage waveform.

Title: Grout material of bedrock and grouting method
Inventor: KATO TETSUO
IPC: E02D3/00
Filed: 1994-10-14
Abstract: PURPOSE: To improve workability by using a mixed liquid containing cement, water and water swelling fibers, in which absorption, fiber length and a fiber diameter are specified, as a grout material forming an impervious wall by injection into the cracked section of a bedrock. CONSTITUTION: High water-absorbing fibers, in which absorption is decuple or more of their own weight, fiber length is 8-50mm and fiber diameters are 1-50 denier, are used as water swelling fibers. When a first grout material G1 , consisting of a fiber mixed liquid is injected into a foundation rock R, the first grout material G1 , is flowed into opened cracks K. The fluidity of the grout material G1 is increased because fiber surfaces absorb water and have smoothness at that time, and fibers are deposited in the cracks K at low injection pressure and close the cracks K. When a second grout material G2 composed of a cement suspension is infected at pressure higher than the grout material G1 the second grout material G2 is infiltrated and fixed into the cracks K and fine cracks in the peripheries of the cracks K and consolidated.  All materials are mixed desirably, and one-stage execution of works is conducted. Accordingly, fluidity can be controlled easily, the dispersion of an injection liquid can be prevented, and strength can be increased.
