Abstract: PURPOSE: A tire pressure control system absorbs instantaneous impact when going over a protrusive object in a road surface, thereby improving driving stability and riding comfort. CONSTITUTION: Both sides of a boot(12) keep sticking on stoppers(20)(22) when tire pressure is constant. Under these circumstances, when a driving car goes over a protrusive object in a road surface, tire pressure is increased by impact applied to a tire. In that case, when tire pneumatic is increased enough to overcome elastic force of an elastic member(14), tire pneumatic compresses an elastic member(14) comprising the boot(12). When the boot(12) and the elastic member(14) is contracted, internal space of the tire is expanded, and then tire pneumatic pressure is decreased by making air as much as space of the tire is expanded flow into a cylinder(8). Thus, when instantaneous impact is applied, decreasing internal pressure of the tire absorbs impact.

Filed: 1999-12-27
Abstract: PURPOSE: A DC generator is provided to prevent life expectancy of a smoothing condenser from being reduced and output loss from being occurred by inserting a metallic thin film condenser to the smoothing condenser in parallel. CONSTITUTION: A resistance(306) is used to drive SCR. Condensers(316,318) are smoothing condensers to convert an AC power to a DC. The condensers(316,318) are electrolytic condensers for low frequency of 120Hz and have a rated capacity of 15,000uF/160V. Meta thin film condensers(320,322) for high frequency are inserted to the two smoothing condensers(316,318) in parallel. While the smoothing condensers(316,318) for low frequency have the rated capacity of 1500uF/160V, the metal thin film condensers(320,322) for high frequency have a capacity of 0.47 to 1uF. A high frequency signal inputted to a circuit is bypassed through the metal thin film condensers(320,322), such that the smoothing condensers for low frequency are not affected by the high frequency.

Abstract: PURPOSE: An apparatus and a method for constructing a CTI(Computer Telephone Integration) telephone driver supporting TAPI(Telephony Application Programming Interface)/TSPI(Telephony Standard application Programming Interface) standards is provided to embody extrinsic services, provided by various exchanges, in an application level using a standard API(Application Programming Interface) by offering a software structure of a telephone driver covering the interface between a computer and an exchange. CONSTITUTION: A TSPI library(100), as a library of TSPI function lists for TAPI function calls, embodies function calls by application. A line handler(110) manages line devices and a line device list and processes the function calls of the TSPI library(100) by lines. A command maker(120) modifies each device function call, requested by the line handler(110), into a command so that an exchange can recognize it, and records the command in the output queue of an I/O queue handler(130). The I/O queue handler(130) reads the command from the output queue through an event sender(160) and an event receiver(170) and transmits it to the event sender(160). Also the I/O queue handler(130) receives an event from the event receiver(170) and stores it in the input queue of the I/O queue handler(130). An event handler(140), checking the input queue of the I/O queue handler(130) periodically, executes event analysis work if an event is transmitted from the exchange(300).

Abstract: PURPOSE: A self-diagnosis method for a rail pressure sensor is provided for an ECU(Electronic Control Unit) to perform a safety mode through detecting an error in a sensor by comparing a signal from a rail pressure sensor with a controlling signal of a rail adjusting signal. CONSTITUTION: In case of a crank angle sensor deciding a normal engine RPM(Revolutions Per Minute), a rail pressure sensor decides a normal signal from an ECU(Electronic Control Unit). In case of a normal detect signal from the rail pressure sensor, a pulse width modulate signal for controlling a rail pressure adjusting valve is detected. A specific fuel pressure is generated by subtracting a real fuel pressure from an established fuel pressure in the ECU. In case of the normal fuel pressure, an average common rail pressure is calculated. In case of the calculated average common rail pressure value between minimum and maximum values, the common rail pressure sensor is decided to be normal.

CONSTITUTION: A service user inputs a phone-to-PC intelligent service identification number, a service subscribing number received from an operator, and a called PC number(S10). An AIN switch receives a digit from the service user and transmits an AIN service request message to a phone-to-PC intelligent service server system(S11). A phone-to-PC intelligent network server system inquires a subscriber profile and identifies a state so that a called PC receives a phone-to-PC service(S12). It is checked whether the called PC receives the phone-to-PC service(S13). If the called PC receives the phone-to-PC service, a phone-to-PC intelligent service server system requests the connection of a channel for transmitting a calling wire telephone and a voice to a phone-to-PC intelligent client system(S14). The phone-to-PC intelligent service server system informs that the phone-to-PC service is requested to the called PC(S15).
