Abstract: PROBLEM TO BE SOLVED: To facilitate the signal processing for the acoustic signal processing unit in which an acoustic signal with high resolution and high quality is decoded even when a dither is inserted to a frequency band higher than an audible frequency band through high frequency sampling and noise shaping. SOLUTION: Code information of an N-bit digital acoustic signal obtained by A/D-converting to a sequential sampling value resulting from sampling an acoustic signal with a sampling signal having a sampling frequency in excess of twice an upper limit frequency of an audible frequency band is divided into N-bit code information for an audible frequency band and into N-bit code information for a frequency band higher than the audible frequency band by band split filters 60, 61. After applying decimation 64 is applied to the N-bit code information for the audible frequency band, the result is given to a bit number conversion section BNC, in which the result is converted into M-bit code information in the relation of M>N.  The M-bit code information outputted from the bit number conversion section BNC is up-sampled (65) and the result and the N-bit code information outputted from the band split filter 61 are added by an adder section 63 while the most significant digits of them are in matching with each other.

Abstract: @ This invention relates to the manufacture of foam from phenolic resins and to the foam so produced. In order to overcome some the the limitations of the prior art closed cell phenolic foams, we have developed a method of preparing closed cell foams from modified, low cost phenol formaldehyde resoles, which exhibit high closed cell contents, low friability and low thermal conductivity. This specification provides a foam competitive with urethane foams, which have an aged thermal conductivity of about 0.16K. or less, but which will not generate fumes as toxic as those of urethane. There is, provided a method of making a phenolic foam material comprising the steps of1) preparing a base catalysed phenol-formaldehyde resole having a mole ratio of phenol to formaldehyde of between 1:3 and 1:4.5 and containing substantially no free phenol but including residual formaldehyde;2) neutralizing, concentrating and acidifying said resole;3) reacting with co-reactants consisting essentially of urea and resorcinol in an amount such that the molar ratio of combined urea and resorcinol to free formaldehyde in said resole is about 1:1, the ratio of urea to formaldehyde being selected so that in a test starting at ambient temperature a reaction temperature of 70° to 75°C. is reached during foaming within a period of 4 to 8 minutes, the urea being reacted first where urea and resorcinol are separately reacted with the resole;4) (a) combining the product of step 3 with a surfactant in an amount sufficient to be effective as a cell stabilizer and(b) a blowing agent in an amount sufficient to form a foam;5) initiating foam formation by adding to the mixture of step 4 a catalyst comprising an acidic material to reduce the pH of the mixture to below 4;6) curing the mixture of step 5.

Abstract: beta -Carotene and canthaxanthin, as representative carotenoids, and to a lesser extent, retinoic acid, a representative retinoid, undergo extensive oxidation to yield substances, insofar as oxidized  beta -carotene is a model, which have properties useful as non-toxic agents active against cell proliferation, tumors, and tumorigenic viruses, and useful as promoters of cell differentiation. It is evident from chemical analysis of the highly oxidized  beta -carotene product mixture that none of the various forms of vitamin A are present or are present only in minor amounts. Furthermore, the biological activities of oxidized canthaxanthin and retinoic acid, which cannot form, vitamin A, indicate the presence of active substances that are different from vitamin A. Although the anti-proliferative and differentiation promotion activities of oxidized  beta -carotene resemble those of vitamin A itself, generally the effects are more powerful for oxidized  beta -carotene in a wide variety of circumstances. Unlike vitamin A, the oxidized  beta -carotene of the invention is non-toxic.
