The first placement bin and the second placement bin are each configured to receive a mosquito-repellent pad. The installation cavity is provided with a heating unit, a first heat conduction unit, and a second heat conduction unit. The heating unit is sandwiched between the first heat conduction unit and the second heat conduction unit and configured to heat the heat conduction units. The first heat conduction unit is configured to heat the mosquito-repellent pad in the first placement bin, and the second heat conduction unit is configured to heat the mosquito-repellent pad in the second placement bin.

Abstract: A machine and its associated process for upset forging the ends of deformed reinforcement bars are disclosed. The machine includes 2 split clamping dies and an upsetting die, and they are housed in separate casings so that the clamping action is independent from the upsetting die. The clamping dies and the upsetting die form a continuous cavity for accommodating the forging of long bars. The upsetting die has a upsetting cavity with radial closed cross-section, and the whole forging process is performed inside this closed cavity to ensure it's a true closed-die forging process, which results in precise upset diameter with improved roundness of the rebar.

Abstract: A braking control device for a motor driven vehicle includes a wheel rotation speed sensing part which is disposed on each wheel of the vehicle and detects a detection speed of wheel rotation of the vehicle, a wheel rotation speed estimation part which detects a resolver value of a motor and estimates an estimation speed of wheel rotation using the detected resolver value, a sensor determination part which determines whether the wheel rotation speed sensing part is abnormal using the detection speed of wheel rotation and the estimation speed of wheel rotation, and a wheel rotation speed determination part which determines the estimated estimation speed of wheel rotation to be a wheel rotation speed of the vehicle when the wheel rotation speed sensing part is abnormal.
