Title: Circuit for controlling accelerator and brake simultaneously
Inventor: LIM JONG GUK
IPC: B60T8/00
Filed: 1998-11-24
Abstract: PURPOSE: A circuit for controlling an accelerator and a brake simultaneously is provided to operate the functions of the accelerator and the brake at the same time by controlling the functions of the accelerator and the brake of a motor vehicle. CONSTITUTION: A driver steps on a pedal(1) in a pedal controlling unit(10) and the arrow of a variable resistance moves from a to c to b. While the driver releases the pedal, the arrow of the variable resistance moves from b to c to a. Herein, if the driver steps on the pedal while traveling, the variable resistance value corresponding to a to c to b is supplied to a microcomputer(20). Then, the microcomputer outputs a command controlling a spraying device(30) of fuel according to the resistance value varied in the a to c section. Moreover, the spraying device of fuel adjusts the spraying amount of fuel according to the command from the microcomputer. When the pedal is located in the c section, the microcomputer controls the spraying device of fuel to spray extremely small amount of fuel, and transfers the controlling command corresponding to the resistance value varied from the c section to the c to b section for operating the brake.

Inventor: LEE SANG HA
IPC: F03B13/12
Filed: 1998-11-30
Abstract: PURPOSE: A method of obtaining energy with larger yield is provided to lift a heavy object up by having buoyant energy larger than injection energy. CONSTITUTION: An air tube(1) is lifted up and then left air/water tubes(1,2) are also lifted by buoyancy in a water tube(2) when the water tube is filled with water. The air/water tubes are located on the lower left and the water tube covers the air tube as much as water soaks through the air tube slightly. When water is supplied to the water tube, buoyancy lifts the air tube up and the water tube follows the air tube. The buoyancy is larger than water energy supplied to the water tube. After that, the water is drained by opening a valve of the water tube and the tubes are returned. The process is repeated by feeding water to the water tube again.

Title: Methods for improved rheological control in cementitious systems
IPC: C04B103/44
Filed: 1996-12-13
Abstract: In accordance with the present invention, a microbial polysaccharide having the features characteristic of S-657 has been found to be effective to improve the rheological properties of a variety of cementitious systems. Thus, the addition of a small, but effective amount of S-657 to such cementitious systems as portland cement, self-leveling grouts, fresh or saltwater oil well cement slurries, microfine cements, and the like, gives rise to substantial improvements in such properties as bleed, flow resistance, fluid loss control, and the like. S-657 addition provides enhanced rheological control in a variety of cementitious systems. In addition, S-657 provides a number of advantages relative to prior art systems, including improved free water and sedimentation control, as well as reduced fines loss during underwater placement. This unique biogum has been shown to enhance the stability of highly diluted microfine cementitious systems, and enhance the flow and workability of superworkable and self-leveling pastes. The homogenous set cement resulting from the introduction of S-657 into cementitious systems promotes bond strength and eliminates the need for vibrated concrete. Efficient free or bleed water control eliminates unsightly vugs or voids adjacent to the form work and thus enhances the appearance of the finished concrete. This highly efficient polymer provides additional benefits as well, such as, for example, enhanced color delivery in pigmented concrete and stabilized bubble entrapment in so called foamed or cellular cement systems. When used in sprayable cementitious systems, S-657 reduces rebound and sag.

Title: Transmit sequencing
Inventor: HORTON ROBERT R
IPC: H03L3/00
Filed: 1997-04-17
Abstract: PURPOSE: A method and apparatus for initializing a radio transmission apparatus are to avoid generating unwanted interference in neighboring radio channels. CONSTITUTION: A phase locked loop is a circuit which includes a phase detector, a filter, and a voltage controlled oscillator. The voltage controlled oscillator is enabled and the phase locked loop is switched from a narrow bandwidth mode to a wide bandwidth mode by placing a logic low on the transistor such that give fast settling time and reduced overshoot. After the phase locked loop has settled, the power amplifier is ramped on to allow the phase locked loop to track the ramp up which keeps the perturbations in the signal fairly minor. Once the power amplifier has substantially reached the final power level, the phase locked loop is switched from the wide bandwidth mode to the narrow bandwidth mode. Thus, with the power amplifier and the phase locked loop turned on at the correct bandwidth, that is, narrow bandwidth, modulation of the transmission signal begins. Therefore, a radio transmission apparatus is initialized. In addition, after the transmission apparatus stops modulation of the transmit signal, the generation of unwanted interference in neighboring radio channels is avoided when a transmission apparatus is turned off by switching the phase locked loop to a wide bandwidth mode and by ramping down the power amplifier.
