Abstract: A quantitative material supply mechanism: an accommodation bucket, a delivery device, an adjustment device, and a quantitative feeding bucket. The accommodation bucket includes an outlet defined on a bottom thereof. The delivery device includes a conveyor belt, a drive roller, a driven roller, and a driving unit. The driving unit is connected with the drive roller and drives the drive roller to rotate, and the drive roller matches with the driven roller to actuate the conveyor belt to rotate. The adjustment device is arranged above the conveyor belt and is located between the accommodation bucket and the turnaround portion. The adjustment device includes two adjusters and two actuation units opposite to the two adjusters respectively. The quantitative feeding bucket is mounted below the turnaround portion of the conveyor belt so as to hold the materials which are delivered by the conveyor belt and drop from the turnaround portion.

Abstract: A computer-based menu management system and method creates a record for each of the menu options in a main menu of an electronic device, creates a sub-record for each of sub-menu options in a low hierarchy of each of the menu options, and assigns initial values to parameters of each record and each sub-record. The system and method further adds a predetermined value to each of the parameters of each record or each sub-record, in response to each visit to a corresponding menu option or a corresponding sub-menu option. In addition, the system and method totals current values of the parameters, and sorts the menu options and sub-menu options of each of the menu options according to the current values of the parameters of each record and each sub-record in a predetermined sorting period.

Abstract: The present invention discloses an electrical connector, comprising an insulating body disposed with a plurality of receiving holes, each of which is disposed with a first terminal and a second terminal inter-penetrating each other, wherein the second terminal is a flat shape and the first and second terminals are inclinedly arranged in the terminal receiving hole; and an elastic body disposed between the first and second terminals. The second terminal of the electrical connector is a flat shape so that it may be manufactured by stamping, which is a simple manufacturing process; the first and second terminals are inclinedly arranged in the terminal receiving hole of the insulating body, which can enhance the arrangement density.
