摘要:
When the impact resistant resin composition comprising a graft polymer in which an aromatic alkenyl compound and an alkenyl cyanide compound are grafted on a rubbery polymer, and a matrix consisting essentially of an aromatic alkenyl compound-alkenyl cyanide compound copolymer satisfies the following conditions, the composition has an improved vacuum formability and the molded articles obtained by vacuum-forming the same have smaller variations in thickness at any given area and there is a smaller reduction of strength due to contact with foamed polyurethane:(1) the proportion of the rubbery polymer in said impact resistant resin composition is 10-30% by weight,(2) the graft polymer has a degree of grafting of 70-120% by weight,(3) the matrix has an intrinsic viscosity of 0.55-0.80 dl/g as measured at 30.degree. C. in methyl ethyl ketone, and(4) the weight ratio of the aromatic alkenyl compound to the alkenyl cyanide compound in the impact resistant resin composition is in the range of 2.0-2.8. When said resin composition contains further 0.01-2.0% by weight of a diorganopolysiloxane having a viscosity of 5-100,000 centistokes at 25.degree. C. and/or 0.1-3% by weight of a metal salt of a fatty acid, its ability to maintain the strength upon contact with foamed polyurethane is enhanced.

A laminate consisting essentially of a layer of a thermoplastic resin (A) and a layer of a vinylidene fluoride resin (B), the layer of the resin (A) containing (C) polymerized units of an ethylenic unsaturated carboxylic acid ester in a proportion of 3 to 80% by weight based on the total weight of the layer of the resin (A). The polymerized units (C) of an ethylenic unsaturated carboxylic acid ester may exist either as a copolymer constituent of the resin (A) or in the form of an ethylenic unsaturated carboxylic acid ester polymer (C') blended in the layer of the resin (A).

A method of configuring a soldering device includes the steps of purchasing (or offering for sale) a soldering device package including a handle, a power cartridge containing an AA battery, a power cartridge containing a lithium ion battery, and a power cartridge containing a nickel-hydride battery; selecting (or instructing a user to select) one of the three power cartridges from the purchased soldering device package for use with the handle to form a soldering device; and inserting the selected power cartridge in the handle to form a soldering device. The selecting step includes selecting one of the three power cartridges based on a specific use of the soldering device and based on soldering performance requirements of the specific use and based on operating times and relative costs of the power cartridges.

An electronic endoscope comprises an endoscope provided with an imaging device. A signal treating circuit produces color signals from output signals of the imaging device. Image enhancers respectively enhance the edges of the images of the color signals produced by the signal treating circuit. An image enhanced amount setting circuit respectively set the image enhanced amounts by the image enhancers independently of the respective color signals.
摘要:
A magnetic multilayer film 10 includes a structure in which thin films 11 made of a ferromagnetic material and thin films 12 made of an insulating material are alternately laminated with each other. Also, a magneto-optical recording medium has a recording film (magneto-optical film) for recording information, the recording film composed of this magnetic multilayer film 10. A magnetic multilayer film has a large magneto-optic effect and it is excellent in stability. A magneto-optical recording medium uses this magnetic multilayer film.

A drive device for a sewing machine which varies the speed of the auxiliary motor. In a sewing machine drive device, the rotation of a clutch motor is transmitted through a pulley and an endless belt to the spindle of the sewing machine. The rotation of an auxiliary motor is transmitted through a driving sprocket, a timing belt and a driven sprocket and through the pulley to the spindle of the sewing machine. The drive device includes rotation varying means which varies the rotation of the auxiliary motor in response to the variation in diameter of the driving pulley of the clutch motor.
