Title: Electrolyte for driving an al electrolytic capacitor
Inventor: CHO SANG PHIL
IPC: H01G9/02
Filed: 1998-10-09
Abstract: PURPOSE: An electrolyte is provided to increase a spark voltage, lower a resistivity, and enhance a temperature characteristic by mixing ethylene glycol and gamma-Butyrolactone in a certain ratio as a solvent. CONSTITUTION: Ethylene glycol used at a high voltage over 160WV and gamma-Butyrolactone used at a low voltage below 160WV are mixed in a certain ratio of 60-90: 40-10. Electrolyte is a principal factor for an Al capacitor to be tolerated at a rating voltage, so the electrolyte increasing a spark voltage value, having a low resistivity, and available in a wide range of temperature is used in the Al capacitor. The electrolyte mixed with a certain ratio of the ethylene glycol and the gamma-Butyrolactone has a lower resistivity and a high spark voltage.

Abstract: PURPOSE: A transfer device of crossing over an obstacle is provided to keep a horizontal degree of a vehicle body on crossing over the obstacle having a gap. CONSTITUTION: For travelling between low obstacles from high obstacles, the same height as a middle track(6) is maintained by a link(8) until a front track(2) reaches an upper part of the low obstacle.

Title: Active magnetohydrodynamic rate sensor
Inventor: LAUGHLIN DARREN R
IPC: G01P9/00
Filed: 1997-07-02
Abstract: PURPOSE: Disclosed is a magneto hydrodynamic sensor having an annular sense channel containing a conductive liquid proof mass. CONSTITUTION: The sensor includes an annular sense channel containing a conductive liquid proof mass (11, 12). A radial flow is introduced into an annular channel (14) which, in response to rotation of the device, produces a coriolis force and resulting circumferential velocity of the fluid. An electromagnetic winding produces an alternating electromagnetic field directed perpendicular to the annular channel. First and second electrodes (17, 18) sense a time varying electric potential induced between the center of the annular channel and the circumference of the annular channel. The time varying electrical potential is proportional to the strength of the time varying electric field and rotational velocity of the channel with respect to the proof mass. The transformer (23) connected to the electrodes provides for amplification of the signal representing the rotational velocity of the channel with respect to the proof mass.

Abstract: PURPOSE: A method for controlling a power of a terminal in a wireless communication system is provided not to synchronize a frequency while not making a call in order to minimize the power consumption of the terminal. Consequently, the time for using the terminal can be maximized CONSTITUTION: When a subscriber inputs a terminal number, a wireless communication system analyzes the number and then, transmits a call signal including a preamble signal to the terminal on the basis of user identification with the analyzed number. The wireless communication system does not detect a place of the terminal but only searches the preamble signal continuously while the subscriber does not make a call. Once the terminal receives the call signal and a preamble detector at the terminal detects the preamble signal, the ID code (Identification code) at the preamble signal is compared with the ID code at EPROM (Erasable and Programmable Read Only Memory). If those two ID codes do not coincide with each other, the preamble signal is ignored. Otherwise, the terminal transmits a connect request signal to a base station after converting a standby mode to an active mode. The connect request signal is transmitted to a MSC (Mobile Switching Center) in succession, and the MSC connects a calling to the terminal after transmitting an acknowledge signal to the terminal. Thereby, as the preamble signal is supposed to be processed before the terminal searches a pilot channel, a lot of power required for searching the pilot channel can be saved.
