Abstract: A combination toilet unblocking/cleaning apparatus for providing both a toilet unblocking and toilet cleaning tool in one convenient unit. The toilet unblocking tool further includes an adjustable auger, a combined tongs, and a detachable rod. Wherein, the adjustable auger includes two drain cleaning cable connected to a slider and slidable held in an elongated sleeve member; and the detachable rod is removably attached to the adjustable auger to form a combined tongs, constructed in such manner that the rod member can be used individually as drain rod. Also, the combination toilet cleaning tool is using the combined tongs as a handle with a plurality of different detachable bathroom accessories. Accessories may include a brush, a plunger, and a scraper; in which the brush, the plunger, and the scraper are configured to be selectively and removably coupled to the combined tongs.

Abstract: A high linearity voltage-current converter able to compensate for mobility degradation comprises a first constant current source circuit, a first current mirror unit, a second constant current source circuit, a second current mirror unit, a seventh MOS transistor and an eighth MOS transistor. The first current mirror unit is coupled to the first constant current source circuit, and the second current mirror unit is coupled to the second constant current source circuit. The seventh MOS transistor, the first current mirror unit and the second current mirror unit are coupled to each other at a third joint point of a first conducting wire. The eighth MOS transistor is coupled to the seventh MOS transistor. Thereby, the electronic components used in the present invention can operate more efficiently.
