Title: Automatic locking method of mobile phone
Inventor: KANG MIN SEOK
IPC: H04B1/38
Filed: 1998-07-31
Abstract: PURPOSE: An automatic locking method is provided to automatically convert an operation mode of a mobile phone to the speech locking status whenever the speech is terminated. CONSTITUTION: The method first inspects whether a current operation mode is under the speech locking mode when power is turned on. Under the speech locking mode, it is determined whether an input secret number corresponds to a set secret number. When the input secret number is correct, a talk time after input of a key signal is counted or an elapse time after the talk path is disconnected since the key input, is counted. When the counted time elapses a predetermined set time, the current operation mode is automatically converted to the speech locking mode without setting to the speech locking mode by user or turning on of power.

Abstract: PURPOSE: A lateral MOS transistor device is provided for transistor which does not need additional processor, retainers, retains low gate drain and is obtained low gate resistance. CONSTITUTION: The transistor device is provided at least one contact window on the gate electrode. The gate electrode is connected through window. The metal gate electrode contact part is the form of metal strip. The transistor device relates to a lateral DMOST with a drain extension (8). The source contact entirely overlaps the gate and thus forms a screen between the gate and the drain in known transistors of this type. In the transistor proposed here, the source contact (15) does not overlap the poly gate (9) but lies entirely laterally of this gate. The gate itself is provided with a low-ohmic metal contact strip (18), which results in a low gate resistance. A metal screening strip (20) is provided between this gate contact strip and the metal drain contact (16), which screening strip is connected to the source contact (15) next to the tips of the contact strip (18). Said screening strip leads to a major improvement in the power gain at high frequencies, for example in the RF range. The screening strip (20) may be realized together with the source, drain, and gate contacts in a common metal layer
