There is provided a keypad assembly operating a dome switch of a mobile phone. The keypad assembly includes a keypad disposed on the dome switch and having a plurality of bosses protruded from a position corresponding to the movable contacts, and a plurality of metal keys each disposed on the keypad at a position corresponding to each boss and protruding from a surface of the housing at a desired height, each of the metal keys formed with a numeral and/or character display penetrating through an upper surface thereof. Since the metal key is made of metal, it represents a metal feeling, in addition to various colors. Also, since the metal key is slimmed, it minimizes a thickness of the mobile phone. In addition, a process for forming the keypad is minimized thereby to reduce additional cost.

The first flow path guides the lubricating oil picked up by the differential ring gear to the catch tank. The gear is in mesh with the differential ring gear, and picks up the lubricating oil picked up by the differential ring gear. The second flow path is arranged lower than a highest position of an outer diameter of the gear.

A pneumatic tire has a main groove extending along a tire circumferential direction in a tread surface. A plurality of projections having different heights are provided in a groove bottom of the main groove in such a manner that an outer peripheral surface is inclined so as to repeat trough portions depressed to an inner side in a tire diametrical direction and peak portions protruding to an outer side in the tire diametrical direction along the tire circumferential direction.

A method for allocating printed circuit boards to the fitting lines of a fitting system configured for fitting printed circuit boards with electronic components includes: determining requirements for fitting each of a plurality of printed circuit boards with respective components; and allocating the printed circuit boards to fitting lines under predetermined conditions by integral linear programming. The allocation is carried out such that differences between the component variances of the fitting lines are minimized. The component variance of a fitting line represent the number of different components configured to be fitted to all printed circuit boards allocated to the fitting line.

The embodiment of the invention provides a signal processing circuit, a mobile terminal and a signal processing method, the signal processing circuit comprises N+1 antennas, wherein at least a part ofthe N+1 antennas are distributed on a first side edge and a second side edge which are adjacent to each other of the mobile terminal; a radio frequency front-end module which comprises a signal receiving and transmitting end and N-1 signal receiving ends; a single-pole double-throw switch which comprises a first contact, a second contact and a third contact, wherein the signal receiving and transmitting end is connected with the first contact, and the second contact is connected with a first antenna arranged on the first side edge of the mobile terminal; an N-pole N-throw switch. When the mobile terminal is in a vertical screen state, a first contact and a second contact of the single-pole double-throw switch are connected; and when the mobile terminal is in a horizontal screen state, thefirst contact and the third contact of the single-pole double-throw switch are connected. According to the embodiment of the invention, the communication quality of the mobile terminal can be improved.

A query processor's capabilities may be employed to identify a range rows resulting from a user query to be returned. A server cursor may be declared, opened, fetched from and closed in a single batched request in order to avoid keeping state on a database server between requests. A single block fetch may be used within the batch to retrieve a requisite number of rows from a specified ordinal position. Where server cursors are not available, an intermediate table may be used to hold a subset of the rows resulting from the user query, and row numbers may be added to facilitate selecting the range of rows from that intermediate table. Intelligence within a query processor may be leveraged to support identifying the range of rows to be returned without maintaining state between client requests.

The invention relates to the field of casting polishing, in particular to a casting polishing tool. The casting polishing tool comprises a positioning and polishing device and a bearing and clamping device; the positioning and polishing device comprises a worktable, a driving part and a polishing part; the bearing and clamping device comprises a support table, a clamping part and a clamping driving part; the polishing part comprises a bearing box, a rotating module and two polishing modules; the bearing box is mounted at the top of the worktable; the rotating module comprises a rotating disc,and a transmission rod mounted in the center position of the rotating disc; one end of the transmission rod extends into the bearing box; each polishing module is in transmission connection with the transmission rod; and in a working state, the clamping part is in butt joint with each polishing module. Through circular reciprocating rotation of the two polishing modules, castings to be polished can be continuously polished, so that the polishing efficiency is improved; and the castings are clamped through automatic equipment, and manual holding of the castings is prevented, so that the dangerof mechanical equipment to machining workers is prevented.

The invention relates to the technical field of hygiene and safety of public transportation, in particular to an automatic rotation type disinfection pull ring for public transportation.
