A method of manufacturing the sheet-form structure, as well as such thermoplastic resin foams, are also provided.

Abstract: An object to be measured is analyzed by a chemical means or a physical means to make its characteristic value clear, a spectrum of the same object to be measured is obtained by an off-line near infrared spectral analyzer, a calibration indicative of a relation between the spectrum and the characteristic value is obtained, at least one sample is selected from among the same kind of objects to be measured, spectra are obtained by the off-line near infrared spectral analyzer and an on-line near infrared spectral analyzer, a difference between both of the obtained spectra is obtained, a spectrum of the same kind of object to be measured is measured by the on-line near infrared spectral analyzer, the measured spectrum is corrected by the difference between both of the spectra, and the characteristic value of the object to be measured is estimated by using the corrected spectrum and the calibration.

Abstract: A wafer holding hand of the present invention is constituted so that two fixed clamps (2) and one movable clamp (6) are provided on a finger (1). The movable clamp (6) is supported by a plate spring (8) via a clamp holder (7), and the plate spring (8) is fixed to the slider (9). The slider (9) is driven by an air cylinder (10). The fixed clamp (2) is hook shaped, and the movable clamp (6) is drum shaped. A wafer W is held at three points by the movable clamp (6) and the two fixed clamps (2), and a force is applied to the movable clamp (6) by the plate spring (8) so as to hold the wafer W.

Abstract: A foam molding is disclosed which is light, excellent in bending strength, and excellent in balance between compressive strength and compression permanent strain. The foam molding comprises thermoplastic resin high expanded foams whose overall outer surfaces are covered with thermoplastic resin low-expanded-foam thin layers. The foams are thermally fused with each other through the aforementioned low-expanded-foam thin layers.

Abstract: A plastic foam material composed of a blended resin composition which includes at least two thermoplastic resins and a silane-modified based resin. The blended resin composition consists essentially of 100 parts by weight of at least two thermoplastic resins, from about 1 to about 50 parts by weight of a silane-modified, cross-linked, thermoplastic resin; from about 0.001 to about 2.5 parts by weight of a cross-linking catalyst for use in a silane compound and from about 1 to about 20 parts by weight of a foaming agent. According to one embodiment of the present invention, the thermoplastic resins include at least two substantially incompatible and substantially uncross-linked thermoplastic resins, while in another embodiment the two thermoplastic resins need not be substantially incompatible. The blended resin composition may further include reinforcers such as glass fibers and filler. The thermodecomposition foaming agent decomposes at sufficiently high temperatures to yield a plastic foam material.
