Title: Internal combustion engine capable of increasing the output power
Inventor: MEYER SIEGFRIED
IPC: F02B1/14
Filed: 1999-01-12
Granted: 2001-04-11
Abstract: This invention relates to the improved structure of a internal combustion engine capable of increasing the output power. The key structure comprises a cylinder, a connecting rod, at least a crankshaft, and a output bearing. The upper end and the lower end of the connecting rod are respectively sleeved with a piston bushing and fixed bushing which the internal diameter and external diameter are not concentric circles and the thickness of the bushings are uneven, and connected to the piston and crankshaft by piston bearing and fixed bearing respectively. Since the body thickness of the piston bushing and fixed bushing are uneven, the piston is pushed upward due to the eccentric effect of the connecting rod or crankshaft, when the piston passes over the upper dead point and intend to descend downward, to maintain the optimal compression ratio in the cylinder, and the cylinder is ignited to explode at this time to obtain the power. Therefore, this invention can not only prevent the deficiency of the conventional internal combustion engine which has to ignite to explode before the upper dead point, but also achieve the efficiency of saving the fuel and reducing the air pollution.

Filed: 1999-01-25
Granted: 2001-07-01
Abstract: Interferometric apparatus and method for measuring and monitoring intrinsic optical properties of a gas, especially the reciprocal dispersive power of the gas, so that information about the gas properties can be used in downstream applications, such as interferometric distance measuring instruments, to increase accuracy by correcting for refractive index of the gas and especially environmental and air turbulence effects in the measurement path. The apparatus comprises a concentric measurement cell having an inner chamber containing a vacuum surrounded by an outer occupied by the gas. Wavelength selective mirrors are arranged at each end of the measurement cell and operate in conjunction with plane mirror interferometers to change the phase of orthogonally polarized components of light beams of different wavelength introduced in the measurement cell from opposite ends of the cell. Preferably, the polarized components are frequency-shifted to facilitate the generation of heterodyne and superheterodyne signals which contain information about the intrinsic optical properties of the gas. The heterodyne and superheterodyne signals are electronically analyzed by a general purpose computer programmed for that purpose or from a specially programmed microprocessor.

Title: Semiconductor memory
Inventor: IMAMIYA KENICHI
IPC: G11C16/02
Filed: 1999-01-29
Granted: 2001-06-16
Abstract: The subject of this invention is to prevent the occurrence of a writing fault even in the case that memory cell with a fast writing speed exists and writing is performed when the common source line potential of memory cell for considering the write verifying read is floating and varied. After sufficient writing of a memory cell (S14) to be written via a cycle of a writing operation (S12) and a write verify reading operation (S13) is decided, a reversely reading operation is conducted. This reversely reading operation is to invert the logic of a sense amplifier from the normal reading operation such that the potential of a word line is set to a voltage larger than the voltage at the time of normally reading operation and less than a voltage at the time of write verify reading operation (S16). After data of the sense amplifier circuit is once reset as the loaded data, the write verify reading operation is conducted (S17). Thus, a writing fault caused by the floating of a potential for a common source line of the memory cell can be prevented.

Title: Methods and systems for distributing liquid chemicals
Inventor: SHIU MIN-DI
IPC: H01L21/304
Filed: 1999-09-22
Granted: 2000-07-01
Abstract: Briefly, this invention uses one or more pressure vessels having installed therein on its inside a balloon of flexible and non-expandable wall to smoothly and continuously deliver a chemical to any end user without contamination and gas dissolution. Since the balloon installed inside the pressure vessel isolates a high pressure gas from the chemicals, gas dissolution in the chemical and the resulted gas bubble problems are effective eliminated. Further, contaminants in the high pressure gas which fills the balloon will not be transferred into the chemical and the extremely toxic chemical will not be transferred into the gas to be exhausted as a serious environmental issue. Unlike the vacuum/pressure systems, the contamination by the ambient air leaking into the system is avoided because the disclosed delivery system is always with the pressure higher or equal to the ambient pressure.
