Title: Urea-surfactant clathrate and its use for bioremediation of hydrocarbon-containing soil and water
Inventor: RAMESHIYU BARADARAJIYU
IPC: C11D1/44
Filed: 1995-09-04
Abstract: PROBLEM TO BE SOLVED: To obtain the subject new compound comprising the adduct of urea to a nonionic surfactant such as an alkylethoxylate, effective for enhancing the bioremediation of soils and water contaminated with hydrocarbons and useful for bioremediation, or the like.  
     SOLUTION: This new urea-surfactant clathrate effective for enhancing the bioremediation of soils and water contaminated with hydrocarbons comprises the adduct of urea to at least one nonionic surfactant selected from the group of non-ionic surfactants consisting of alkylethoxylates, alkyl ethoxylated phosphates, alkyl ethoxylated amines, alkylethoxylated ammonium salts, alkyl ethoxylated sugars, and alkylethoxylated polyhydric alcohols and their cyclic ethers. The clathrate is obtained by adding the urea and at least one of the nonionic surfactant to methanol, heating the mixture until both the urea and the surfactant are dissolved in the methanol, cooling the solution to room temperature, gradually evaporating the solvent, filtering off the formed crystals, washing the crystals and subsequently drying the crystals.

Title: Generating method for television signal
Inventor: MATSUMOTO KOJIRO
IPC: H04N7/00
Filed: 1986-09-25
Abstract: PURPOSE:To realize an aspect ratio which is laterally longer than before and to maintain compatibility with the conventional NTSC system by multiplexing mean values of block units of a subordinate image signal on the time base and receiving an NTSC system signal where a difference value is multiplexed on the frequency base. CONSTITUTION:An input signal which has a >=(4:3) aspect ratio is supplied to a frequency base separating circuit 2, which separates and supplies the difference signal of the NTSC system frequency-base multiplexed subordinate image signal to a time-base compressing circuit 6. A time-base separating circuit 3 separates the mean value of the subordinate image signal which is multiplexed on the time base in a blanking period and then supplies it to a time-base expanding circuit 5. Said separated signal is decoded by an NTSC system decoder 4 into a main image signal. The circuits 5 and 6 obtain an original frequency spectrum from said mean value signal and difference signal. An adder 7 adds the output signals of the circuits 5 and 6 to regenerate the subordinate image signal. An image composing circuit 8 composes one signal of the main image signal consisting of an image with a 4:3 aspect ratio and an image of a wider area.

IPC: B29C43/02
Filed: 1999-08-10
Abstract: PROBLEM TO BE SOLVED: To precisely transfer the surface shape of a mold regardless of the surface shape of a Fresnel lens to be manufactured and also regardless of the small pressurizing force to be applied in a pressing process. SOLUTION: In a Fresnel lens manufacturing method, a slit-shaped channel 11 is formed on the surface of a lens material 10, and the lens material 10 with the channel 11 formed thereon is pressed in a mold, and the lens material 10 formed by the pressing is released from the mold to manufacture the Fresnel lens. In that case, the slit-shaped channel 11 is formed into the radial shape on the lens material 10. Thus air in a cavity formed between the mold and the lens material 10 when the lens material 10 is pressed in a mold is passed through the channel 11 and released outside, and the lens material is applied all over the corners of the mold even when the pressurizing force in pressing is small to precisely transfer the surface shape of the mold to the lens material 10.

Title: Production of optical recording medium
Inventor: HIRASAKI MICHIYA
IPC: G11B11/10
Filed: 1986-09-25
Abstract: PURPOSE:To suppress the penetration of moisture into an optical recording layer and to obtain recording medium having excellent weatherability by embedding the pinholes generated in a protective film with a resist. CONSTITUTION:An Al10Si90N is film 2 is formed to about 1,000Angstrom as a protective layer by a sputtering method on a PC substrate 1. The resist is then formed to about 1,000Angstrom  thickness by a spin coating method thereon and is heated for about one hour at 80 deg.C. The resist is thereafter subjected to sputter etching with Ar ions to remove the resist except the pinhole part of the film 2 which the protective layer is formed. The recording medium provided with a plurality of such layers suppresses the penetration of the moisture from the PC substrate 1 to the recording film and obviates the corrosion of the recording film even in a extended accelerated test. The medium having the excellent weatherability is thus obtd.
