To provide a toner, containing: a crystalline polyester resin; and a non-crystalline polyester resin, wherein the crystalline polyester resin has a melting point of 60° C. to 80° C., and wherein the toner satisfies the relationship represented by the following formula: (W1−W1′) / W1<0.50, where W1 is a temperature width at a 1 / 3 height of a height of an endothermic peak of the crystalline polyester resin at the time of an initial temperature elevation on a DSC curve of the toner as measured by differential scanning calorimetry, and W1′ is a temperature width at a 1 / 3 height of a height of an endothermic peak of the crystalline polyester resin after the toner has been heated at 50° C. for 24 hours.

Provided is a pneumatic tire having improved driving stability and wear resistance on dry road surfaces as well as an improved running performance on snow. The present invention provides a pneumatic tire designed to be mounted on a vehicle so that a designated side of the tire should face to the outside of the vehicle. The pneumatic tire includes a tread portion provided with: a first main groove extending in a tire circumferential direction; a second main groove extending in the tire circumferential direction in a shoulder region closer to the center of the vehicle than the first main groove; a third main groove extending in the tire circumferential direction in a shoulder region farther from the center of the vehicle than the first main groove; and a plurality of lug grooves each extending from one shoulder side to the other shoulder side. Moreover, in the pneumatic tire, a width of a first land section defined between the first and second main grooves is set greater than a width of a second land section defined between the first and third main grooves, a plurality of inclined grooves are provided in the first land section, each inclined groove communicating with at least three of the lug grooves while being inclined to the tire circumferential direction, and one end of each inclined groove is opened to one of the lug grooves while the other end thereof is terminated within a block.

A self-supporting heliothermal flat collector module includes a sheet metal panel; a register-type arrangement of capillary tubes separated from one another for the flow of a fluid medium that lies on the rear side of the sheet metal panel opposite that to be irradiated; and a thermally-insulating insulation core also positioned on the rear side. According to the invention, the capillary tubes of the register-type arrangement are placed into contact with the surface of the thermally-insulating insulation core, and the thermally-insulating insulation core is attached to the sheet metal panel by means of an elastic adhesive layer, whereby the capillary tubes are at least partially embedded into the adhesive layer between the sheet metal panel and the insulation core.

A method for measuring the temperature of a heat pipe includes the steps of: firstly preparing a thermal couple wire formed at one end thereof with a temperature-sensing head, pressing the temperature-sensing head on the surface of the heat pipe to be measured, and a proper amount of a fluid medium is filled between the temperature-sensing head and the surface of the heat pipe. The fluid medium can be water, oil or flowable paste having lower viscosity. Due to the cohesion of the fluid medium, it can fill the gap between the temperature-sensing head and the surface of the heat pipe. As a result, the stability of the thermal contact resistance between the point-contact of the temperature-sensing head and the heat pipe is increased due to the filling of the fluid medium. Also, the contact effect is greatly enhanced to reduce the thermal contact resistance.
