摘要:
A fluororesin-coated material having markings indicated thereon is disclosed, which material comprises (1) a substrate having coated thereon a fluororesin composition comprising a high-molecular weight material having a benzene ring and at least one of a nitrogen atom, a sulfur atom and a carbonyl group in the main chain thereof, or (2) a substrate having coated thereon the high-molecular weight material, and further having coated on the high-molecular weight material a fluororesin composition. The markings are indicated on the coated material by irradiating the coated surface of the coated material with electromagnetic waves having a wavelength of 600 nm or less to thereby cause a change in the color of the high-molecular weight material at irradiated parts and provide a difference in color between the irradiated parts and unirradiated parts.

A sheet pressure-sensitive sensor (piezoelectric device or the like) (4) is provided over a flat-plate heater (1) to which a heater-current supplying line (2) is connected. The pressure-sensitive sensor (4) is sandwiched between thin insulation sheets (3). A spacer (6) formed of a metallic plate having a hole into which the pressure-sensitive sensor fits is provided between the thin insulation sheet (3, 3). A signal line (5) of the pressure-sensitive sensor (4) is connected to a control device and the heater-current supplying line (2) is connected to a power supply that is capable of being controlled by the control device. With this structure, it is possible not only to maintain the body temperature of a small animal but also to detect the heart rate and respiratory rate of the small animal placed on the pressure-sensitive sensor (4) with the pressure-sensitive sensor (4) and supply the detected values to the control device for measuring and monitoring the heart rate and respiratory rate of the small animal.
摘要:
A method for treating the surface of a thin porous film material of tetrafluoroethylene resin is disclosed, which comprises heating said surface to a temperature higher than the thermal decomposition point of said resin so as to decompose and remove part of said surface. The resulting thin porous film material of tetrafluoroethylene resin has an adhesive surface while retaining the desired pore size, hardness, and degree of penetration of adhesive.

The present invention is directed to a cooking container for use in heating food in a microwave oven. Specifically, the present invention concerns a cooking utensil capable of heating itself up by microwaves to heat food to such an extent as to be browned but not to be scorched and be stuck to the cooking surface. A fluororesin layer 1 is formed on the top surface of a metal plate 2, and a heat buildup layer 3 adapted to be dielectrically heated by microwaves is formed on the bottom thereof. A covering 4 permeable to microwaves is provided on the outside of the heat buildup layer. The covering is partially formed into legs to support the bottom surface of the plate. A lid capable of reflecting microwaves may be put on the metal plate to shield the food to be cooked against microwaves.
