Abstract: A manually resettable thermostat has several individual resettable thermostats which have respective calibration temperature, stacked one above the other and formed as an integral assembly. The thermostat may be utilized in the thermostatic system that need several different manually resettable thermostats with different calibration temperatures so the space of the system is saved and the operation of the thermostat is simplified.

Abstract: A heating vessel comprises a bottom portion made of conductive material and perimeter wall extending upward from the bottom portion to form a perimeter and covers the vessel such as to form a cavity. The perimeter wall comprises an outer wall and an inner wall, and at least an adiabatic portion defined between the outer wall and the inner wall, which is as an adiabatic layer. The dimension of the inner wall is less than the outer wall. The inner wall is connected to the bottom.

Abstract: A cooking method comprises heating step, which involves heating foodstuffs into pan to first predetermined temperature with the purpose of food safety, lowering heating powder so as to enter slow pan mode, and then increasing temperature slowly and constantly to a second temperature of foodstuffs aging. The method further comprises the step of allowing the main heater to stop heating after reaching the second temperature, then entering cooling step so as to lower pan temperature naturally to above third predetermined preservation temperature while maintaining little heat source at bottom of pan during the cooling step, so as to maintain convection in pan and allow foodstuffs temperature uniform.

Abstract: A guiding-tour system and apparatus, including: at least one host, which adheres or near to an exhibition object, and sets an unique discriminate number corresponding to the exhibition object, has a memory slot and at least one wireless transceiver module, at least one memory card is inserted into the slot, a voice guiding-tour data digital file of the exhibition object is recorded in the memory card, and transmits the digital file in the memory card in a wireless manner via the wireless transceiver module; at least one slave handheld by a visitor, the slave being a portable guiding-tour handheld by the visitor, which at least has a wireless transceiver module, may start a download program in a wireless manner, and downloads the voice guiding-tour data digital file stored in the memory card of the host to the slave handheld by the visitor, and playbacks it according to an instruction from the visitor.

Abstract: A manually resettable thermostat has several individual thermostats which have respective manually resettable calibration temperature stacked one above the other and formed an integrative assembly. The thermostat can apply to the thermostatic system that need several different manually resettable calibration temperatures so the space of the system is saving and the operation of the thermostat is easy.

Abstract: A subarea control system of electrical lighting separated by a demarcation repeater 6 comprises: a bus power supply 5 connected to the electric supply 1; at least a demarcation repeater 6 connected to the bus power supply 5 via a bi-phase digital information transmission bus 2 to establish a contact with the uplink bus, while the demarcation repeater 6 need to be connected to the electric supply 1; a system controller 7 connected to the bi-phase digital information transmission bus 2 to form a transmission path 9 so as to broadcast the system instructions within the whole system; at least a subarea controller 8 connected to the bi-phase digital information transmission bus 2; at least a group of lamp controllers 3 respectively connected to the bi-phase digital information transmission bus 2 to receive the information instructions and to access the electric supply 1; the subarea controller 8 and the lamp controllers 3 form a subarea instruction transmission path 10 whose boundary is the demarcation repeater 6,

Abstract: A multifunction lamp comprises: a light source; a first reflector receiving and reflecting the projected light from the light source; a second reflector receiving and reflecting the reflected light from the first reflector; a first light-guide member which is provided between the light source and the first reflector or and the end of the first reflector away form the light source; and a second light-guide member guiding the light reflected by the second reflector out of the lamp.
