The present invention relates to a device for semi-autonomous support of the steering movement of a car, which has a support unit for supplying information for steering position of a vehicle steering and covered distance during a vehicle drive. A target path tuned through a test drive is deposited for fixed ambient in a computer unit. The support unit is formed for the target path by reaching a given position of a vehicle (10) to revert in the fixed ambient and supporting the driver while driving the vehicle (10) along the target path.

The present invention relates to a lower thread supply device for a sewing machine, comprising: a housing (100) which is fixed to a main body of a sewing machine, has a cylindrical shape in which a front side and a back side are opened along a central axis, and has a (a housing cut out portion)(110) formed by cutting the outer circumferential surface of one side; a rotation plate (200) which is connected to a power shaft of a sewing machine, has a disk shape, has a power transmission protrusion (210) formed on the front surface of the disk, and is provided at the back inner lateral side of the housing (100) to rotate; a hook body (300) which is rotatably provided inside the housing (100), has a cylindrical shape with an opened front side, a protrusion receiving part (320) formed at the back outer portion to receive the torque of the rotation plate (200) by being engaged with the power transmission protrusion (210), a bobbin mounting post (330) formed at the back inner portion, and a hook (310) that passes through the loop formed by an upper thread descending along a needle of a sewing machine, thereby pulling the upper thread, provided at the outer circumferential surface of one side; a spool-shaped bobbin (400) which is inserted into the bobbin mounting post (330) of the hook body (300) to be rotatably provided, and to which a lower thread is wound; and a cap (500) which passes through the center of the bobbin (400) to be detachably coupled to the bobbin mounting post (330), thereby preventing the separation of the bobbin from the hook body (300).

The invention discloses a method for the in-situ anaerobic digestion treatment of kitchen garbage, which relates to a kitchen garbage treatment technology. The anaerobic digestion treatment of the kitchen garbage after collection, sorting and pulverization is carried out to acquire marsh gas and digested residues capable of being used for restaurants, and residues are then separated and dried through a centrifuge to acquire available feed. The sludge in a plant anaerobic digestion cell is used as a substrate of an inoculant, and the kitchen garbage is used for domestication, thereby effectively utilizing the microbial flora in the substrate; meanwhile, the habit of the inoculant and the character of the kitchen garbage can be matched through domestication, thereby being beneficial to quickly starting a digester. The method is suitable for the in-situ treatment of the kitchen garbage in community centers of various large and medium restaurants, schools, hospitals and the like.

The present invention relates to a filter with bond separating film or filtering unit, and a self cleaning method. The filter having self cleaning function comprises: a cleaning water storage(500); a filter(200) which is equipped with a disk filter(210) for filtering effluent and is combined with a plurality of hollow shafts(230); a compressed air supply part(300) supplying compressed air to the filter; a filter washing line(510) supplying the cleaning water to the filter; and a plurality of nozzles(511) which is combined with the filter washing line and sprays the cleaning water on the disk filter. The filter having self cleaning function is provided to shorten washing time of a disk filter by automatically spraying cleaning water on the surface of the disk filter and to enhance purifying efficiency of effluent by promoting the production of turbulent flow. Furthermore, the invention improves purifying efficiency of waste water.
