A plastic window includes a plastic window body, a conductive portion, a first bus bar, and a second bus bar. The window body is formed in a plate shape and has a first surface and a second surface on both sides thereof. The conductive portion and the first bus bar are made of a conductive material and disposed on the second surface of the window body. The first bus bar is electrically connected to the conductive portion. The second bus bar is made of a conductive metal strip and disposed to be electrically connected to the first bus bar. The second bus bar has a main body, first fixing portions, and second fixing portions. The first fixing portions fix the main body to the second surface. The second fixing portions extend from the main body along the second surface and are attached to the first bus bar.

In combination with a pipe (213), a clamp (201) is provided which supports the pipe in a fixed position with respect to a substrate. The clamp includes first (203) and second (205) bands, wherein each of the first and second bands has an arcuate portion (209) and first and second terminal portions (211), and wherein the arcuate portions of the first and second bands are disposed in opposing relation around the surface of the pipe. A first fastener (207) extends through the first terminal portions of the first and second bands, and a second fastener extends through the second terminal portions of the first and second bands. A thermal insulator (233) is disposed between the first fastener and the first terminal portions of the first and second bands, and between the second fastener and the second terminal portions of the first and second bands.

A heater apparatus includes a base member, a cover member supported by the base member, a cloth member provided between the base member and the cover member to hold a heater wire, and a heater temperature sensor brought into contact with the cloth member, covered on a base member side facing the base member and a cover member side facing the cover member with the cloth member, and configured to detect a temperature of the heater wire. The cover member has a cover recessed portion recessed towards the base member in an overlapping region where the cloth member on the base member side and the cloth member on the cover member side of the heater temperature sensor overlap.

A system for heating animals. The heating system uses an elongated curved reflector around an elongated infrared light source to reflect heat off of the elongated curved reflector and onto piglets provided in the piglet creep of a farrowing crate. The system has a reduced thermal gradient to efficiently transfer heat to animals, such as piglets, without overheating other nearby animals, such as sows.

A rotatable wax-melting fragrance lamp comprises a base, a housing, a rotating component, a heating component, a light-emitting component, a control PCB, and a heat-conducting plate. By arranging the rotating component, the whole product can present a rotating effect, which can make the lamp have better lighting effect and decorative effect, and enables the heating component to melt and volatilize wax more uniformly; the heat-conducting plate is detachable, which is convenient for cleaning and replacing the fragrant wax; the PTC heating element or ceramic heating resistor is used in place of open fire heater. The heating of the PTC heating element or the ceramic heating resistor is to realize the heating of the fragrant wax, so that the fragrant wax produces a pleasant fragrance, which spreads around the immediate vicinity. The PTC heating element or ceramic heating resistor requires lower heating power consumption, while the power control is very sensitive.

A fuser having a heater, a holder, and a connector, is provided. The heater is in a form of a planar plate. The heater has a metal-made base plate having a recessed portion, a heating pattern having a resistance-heating element arranged on the base plate, and a plurality of power-supplying terminals conductive to the heating pattern. The plurality of power-supplying terminals are located in an end area in the heater on one side in a lengthwise direction of the heater. The holder supports the heater and has a projecting portion configured to contact the recessed portion in the lengthwise direction. The connector has electrodes connectable with the plurality of power-supplying terminals. The recessed portion is located between the heating pattern and one of the plurality of power-supplying terminals closest to the heating pattern in the lengthwise direction.

A metal heater system. More specifically, a plurality of metal heaters is coupled to the surface of the lower end of a pipeline at predetermined intervals in the longitudinal direction of the pipeline, and PTC heating elements inside the metal heaters conduct heat to local portions of the pipeline. Convection is generated in a fluid inside the pipeline because of the heat conducted to the local portions, and thus the overall pipeline is maintained at a constant temperature, efficiently preventing the freezing and bursting of the pipeline in winter.
