摘要:
A process for producing a finely cellular polyurethane foam by mixing a first ingredient comprising an isocyanate compound and a second ingredient comprising a compound containing an active hydrogen group, characterized by comprising adding a nonionic silicone surfactant containing no hydroxyl group to at least one of the first ingredient and the second ingredient in an amount of 0.1 to 5 wt %, excluding 5 wt %, based on the total amount of the first ingredient and the second ingredient, subsequently agitating the surfactant containing ingredient together with an unreactive gas, which has no reactivity to isocyanate group or active hydrogen group, to disperse the unreactive gas as fine bubbles to prepare a bubble dispersion and then mixing the bubble dispersion with the remaining ingredient to cure the resultant mixture and forming finely cellular structure into the resultant polyurethane foam by the fine bubbles of the bubble dispersion.

A polishing pad enabling a highly precise optical endpoint sensing during the polishing process and thus having excellent polishing characteristics (such as surface uniformity and in-plane uniformity) is disclosed. A polishing pad enabling to obtain the polishing profile of a large area of a wafer is also disclosed. A polishing pad of a first invention comprises a light-transmitting region having a transmittance of not less than 50% over the wavelength range of 400 to 700 nm. A polishing pad of a second invention comprises a light-transmitting region having a thickness of 0.5 to 4 mm and a transmittance of not less than 80% over the wavelength range of 600 to 700 nm. A polishing pad of a third invention comprises a light-transmitting region arranged between the central portion and the peripheral portion of the polishing pad and having a length (D) in the diametrical direction which is three times or more longer than the length (L) in the circumferential direction.

摘要:
An element for specifying the condition and type of immune-related diseases on the basis of the knowledge about the polarization of distribution of Th1/Th2 subsets of helper T cells. The element for specifying or correcting the polarization of the Th1/Th2 subsets is implemented by use of a recombinant vector, a transformant, a human-Th1-specific protein, and an antibody which uses the human-Th1-specific protein as an antigen. A human-Th1-specific gene is prepared and specified by a subtraction technique and is incorporated into the recombinant vector. The transformant is formed by transforming the recombinant vector. The Th1-specific protein is encoded by the gene derived from the transformant.
摘要:
In order to achieve check and adjustment of electronic apparatus such as a VTR from a remote location, a tone dialer in a service company converts commands and data into tone signals for checking and adjusting a VTR in a user's house, which tone signals are transmitted by a telephone over a telephone line and input to a telephone in the user's house. The tone signals received by the user's telephone are converted into the commands and data by a gateway and input to the VTR.
摘要:
A polishing pad generates very few scratches on a surface of a polishing object, and is excellent in planarization property. The polishing pad has a high polishing rate and is excellent in planarization property. The polishing pad grooves become very little clogged with abrasive grains or polishing swarf during polishing and, even when continuously used for a long period of time, the polishing rate is scarcely reduced.

摘要:
The invention provides a polishing pad by which optical materials such as lenses, reflecting mirrors etc., or materials requiring a high degree of surface planarity, as in the polishing of silicone wafers, glass substrates or aluminum substrates for hard disks, or general metal polishing, can be flattened with stability and high polishing efficiency. The invention also provides a polishing pad for semiconductor wafers, which is superior in planarizing characteristic, is free from scratches and can be produced at low cost. There is provided a polishing pad which is free from dechucking error so that neither damage to wafers nor decrease in operating efficiency occurs. There is provided a polishing pad which is satisfactory in planarity, within wafer uniformity, and polishing rate and produces less change in polishing rate. There is provided a polishing pad which can make planarity improvement and scratch decrease compatible.
