Abstract: The present invention relates to an equipment for brewing coffee. A water pump, a boiler, a check valve, a water port and a coffee extractor are arranged in the shell of the present invention, the coffee maker is not provided with water tank, the water pump is arranged between the outlet pipe of the boiler and the inlet of the check valve; the outlet of the check valve is communicated with the coffee extractor through the water port. The coffee maker in the present invention can ensure the stability of the water temperature at the water port, so that the coffee is better taste. The coffee maker simplifies the waterway system with low producing cost, high production efficiency, convenient maintenance and easy using.

Abstract: There is provided a cooked rice molding apparatus which enables a rice mat to be easily moved and the rice mat to be stored. A rice mat formed into a plate shape by a forming section 3 is spread over a pick plate 5 placed on a slide tray 4, and the rice mat, along with the pick plate 5, is removed from the slide tray 4.

Abstract: A contact pin for an electrical connector comprises a body, a connector element, and a sheath, the connector element being maintained in the extension of the body by being coupled with a peg projecting from the front face of the body, the sheath being disposed around the connector element and maintained on the body by clamping an annular portion of the latter. At the peg end, connector element comprises an end for coupling with said pin, conformed such that the pin cannot fit inside the cross section of said coupling end, the connector element being capable of deforming elastically to enable its coupling end to friction fit onto the pin, the thus deformed connector element being unable to fit inside the cross section of the sheath.

Abstract: A multiple contact connector which can be used to protect live circuits including power and signal line, during connection and disconnection in wet environments, includes a male probe adapted to removably seat in a female receptacle. The male probe and the female receptacle are constructed to attach to equipment which includes downhole tools. The probe includes at least three uniquely spaced contacts on an outer surface. The receptacle has at least three contacts on an inner surface spaced so as to mate with the probe contacts when the probe is seated in the receptacle. The contacts are spaced such that no more than one of the at least three probe contacts may be aligned with and contacting any of the at least three receptacle contacts, unless said probe is seated within said receptacle. This prevents cross coupling of the live power and signal lines thereby preventing damage to the associated circuits.

Abstract: A connector system comprises at least three different connectors each having a common width and a different depth. Each connector is made up of a block and two housing parts. The housing parts are selected from a group of parts of different depths such that the smallest connector can be made from two identical parts of the smallest depth, the largest can be made from two identical parts of the largest depth and intermediate sizes can be made from combinations of parts of different depths.
