A hinge for portable terminal comprising a first member having a keyboard portion and a second member having a display portion coupled to each other in a manner capable of openingclosing in a vertical direction and rotating in a horizontal direction at a predetermined open angle in the vertical direction. In one embodiment, the invention increases the number of the available clock phases to M and then shifts the output clock phase by one, every KM cycle. Each SM request includes a key set and a name-value pair. Moreover, the mechanical isolation assembly preferably includes bellows through which the refrigerant fluid is conducted. A fuel property is determined based on the engine speed of the operation cylinder and an engine speed of a non-operation cylinder. The voltage supply circuit is provided with a first voltage supply circuit for precharging the driver power supply voltage to a power supply voltage level of a memory cell, and a second voltage supply circuit for supplying a voltage lower than the power supply voltage level of the memory cell as the driver power supply voltage.
