摘要:
A double plug head for plugging a pipe. The double plug head includes a primary rubber packing, a roller support, a tube support and a rubber tube. The primary rubber packing is provided on a mounting plate of a plugging machine. The roller support is provided with a plurality of rollers. The tube support is provided between the primary rubber packing and the roller support. A tube seating depression is formed around the circumferential surface of the tube support. A fluid feed path is formed in the tube support. The rubber tube is seated into the tube seating depression and has a nipple connected to an outlet of the fluid feed path. Communication holes which communicate with the fluid feed path are respectively formed in the primary rubber packing and the mounting plate. A fluid hose is connected to the communication hole of the mounting plate.

摘要:
A method of recognizing proximity using a proximity sensor and a mobile terminal using the same are provided. The method includes detecting a key input by a user, projecting light in a state where an object does not approach a proximity sensor and measuring a light receiving amount of the projected light, extracting a compensation amount corresponding to the measured light receiving amount, setting a critical light receiving amount for determining proximity recognition by compensating the measured light receiving amount with the extracted compensation amount, and recognizing proximity of an object to the proximity sensor based on a preset critical light receiving amount. Thereby, even if the surrounding environment of a mobile terminal is changed, noise characteristic of the proximity sensor is influenced, and the mobile terminal is used for a long time, a proximity recognition distance of the mobile terminal is uniformly sustained.
