A programmable burner for gas stoves, which is constituted by a gas burner and a safety valve that includes a thermocouple, which is located in coincidence with an external edge of the burner. The safety valve is maintained open when the thermocouple is detecting the presence of a flame on the gas burner and is closed when the burner has been turned off. An electrode is placed near of the external periphery of the burner for igniting. A spark generation module is connected with the electrode for generating the sparks for igniting the burner. A spark interrupter is connected to the spark generation module, the spark interrupter being located over a burner knob that is connected to the safety valve, for activating or deactivating the spark generation of the spark generation module. Finally a programmable device is connected with the thermocouple and the security valve, for programming the ignition time of the burner in accordance with a preestablished operation time by user.

An injection-molding nozzle for resin with highly temperature-dependent viscosity as claimed in claim 1, characterized in that the diameter of the rear end hole of said passage is limited to 4-6 mm; the gradient up to said front end hole is set within a range of 1/16.5-1/33; the passage surface is mirror-finished; and thereby the resin is prevented from staying inside, and moreover, the nozzle port of said nozzle tip is set to a gradient of 1/5-1/15 steeper than that of the passage so that the solidified resin in said passage is thoroughly drawn and removed. 5. An injection-molding nozzle for resin with highly temperature-dependent viscosity as claimed in claim 1, characterized in that a heat insulating board provided with a through-hole of the same diameter drilled at the center as the diameter of the front end hole of said passage and the internal diameter of said nozzle port is interposed between the front end face of said nozzle main body and said nozzle tip. 6. An injection-molding nozzle for resin with highly temperature-dependent viscosity as claimed in claim 2, characterized in that the diameter of the rear end hole of said passage is limited to 4-6 mm; the gradient up to said front end hole is set within a range of 1/16.5-1/33; the passage surface is mirror-finished; and thereby the resin is prevented from staying inside, and moreover, the nozzle port of said nozzle tip is set to a gradient of 1/5-1/15 steeper than that of the passage so that the solidified resin in said passage is thoroughly drawn and removed. 7.
