Abstract: A toaster with functions of baking breads and cooking foods comprises a body having at least one receiving space. There are two heating plates, one left heating plate and one right heating plate; the left heating plate and the right heating plate are installed at a left and a right side of the body, respectively; an inner side of each of the left heating plate and right heating plate is formed with a cooking area for cooking. A lower end of each of the left heating plate and right heating plate is formed with a penetrating hole. A shaft passes through the penetrating hole. Two ends of the shaft are installed to the body so that the right heating plate and the left heating plate can rotate along the shaft to be opened or closed.

Abstract: In a working environment positioning system, there is comprised an interface unit for receiving information input by users; a characteristic analysis unit coupled to the interface unit for analyzing characteristic indices of each of the users based on the input information; a compatible-degree analysis unit coupled to the characteristic analysis unit for analyzing a compatible degree of each of the users with other users based on the characteristic indices to generate a plurality of corresponding compatibility indices, from which a compatible-degree matrix is obtained; and a report generating unit for receiving analysis results from the characteristic analysis unit and the compatible-degree analysis unit, analyzing a positioning relation of each of the users in a working environment, and generating an analysis report accordingly. A working environment positioning method and a computer program product for implementing the method are also disclosed.

Abstract: A coolant through spindle device is disclosed, including a rotating joint member secured to the rear end of the spindle for conducting coolant into the spindle, the coolant being conducted through a separate coolant passage inside the spindle to the nozzles formed on a cutting tool to be sprayed out thereof so as to fully cool down and lubricate the cutting point thereof, increase machining precision and cutting rate, and prolong service life of the cutting tool. Moreover, by using a switching collar to provide separated coolant passage and pressurized air passage, no residual coolant can follow the pressurized air jet into the tapper hole of the spindle to contaminate the tapper hole.
