Title: Fuel injection internal combustion engine with sub-combustion chamber
Inventor: UEDA MINORU
IPC: F02M69/08
Filed: 1998-04-17
Granted: 1999-11-21
Abstract: A fuel injection internal combustion engine with sub-combustion chamber in communication with a main combustion chamber. A mixture switching valve is provided for injecting the mixture of the fuel and compressed air, and a spark plug is arranged in the sub-combustion chamber. The sub-combustion chamber is formed of a material having a thermal conductivity which is lower than that of the material forming the main combustion chamber. The combustion efficiency is enhanced even when the fuel is injected to the sub-combustion chamber from the mixture switching valve with low pressure compressed air. An injecting device directly and intermittently injects mixture gas into the sub-combustion chamber. The injecting device is a mixture gas injection device including a pressure accumulating chamber adjacent to the sub-combustion chamber and to which pressure air is filled, and opening or closing valve to cause the pressure accumulating chamber to be communicated with the sub-combustion chamber in such a way that they may be opened or closed, and a fuel injecting valve for injecting fuel into the pressure accumulating chamber. Mixture gas with an air-fuel ratio adapted for an operating state of the engine over a wide operating range is supplied to the combustion chamber. A volumetric ratio of each of the sub-combustion chamber and the main combustion is set within a range of 2:8 to 6:4. A discharging amount of hydrogen carbide is less than a high efficiency can be attained.

Title: Manufacturing method for stickers which can change the shading value according to different lighting condition
Inventor: GAO GUO-KUN
IPC: B32B27/00
Filed: 1998-05-27
Granted: 1999-09-01
Abstract: A kind of manufacturing method for stickers which can change the shading value according to different lighting condition. The method employs spironaphthooxazine powder as the ultraviolet photosensitive material to be appropriately mixed and agitated with plastic material and be produced as a thin film product. When the thin film product is exposed to the ultraviolet ray of the sunshine, the ultraviolet photosensitive material in spironaphthooxazine will change the shading value according to the strength of ultraviolet ray that the thin film product will be dimmed from transparent and increase the dimmed level according to the ultraviolet strength. Therefore, the thin film product can be attached on the vehicle glass or window glass of the buildings so that the glass on vehicle or on buildings can keep better transparency in cloudy weather or at night. The limited light can penetrate into the vehicle to keep driving safety and to keep enough indoor brightness in the buildings in cloudy weather or with weak lighting condition that there is no need for too much light and save the energy. When the ultraviolet ray is strong, the vehicle glass or building glass will be dimmed to prevent the penetration of sunshine and the damage to human body and achieve automatic brightness adjustment.

Similarly, a second port may be used for read or write operations and may be accessed only during a second portion of the timing cycle. To ensure that the multi-port memory cell functions correctly, both ports should not be accessed simultaneously. A circuit and method are implemented to ensure that both ports are not accessed simultaneously by implementing a delay function in a unique and useful manner.

Filed: 1999-03-19
Granted: 2000-11-11
Abstract: Anisotropically mapping of texture information to each pixel required for display of each of plural polygons forming each scene on a CIG display in a computational efficient manner, uses the footprint of each transformed pixel silhouette, as mapped from image space into the texture array, to determine an anisotropic texture space area having both a related length and a related width, in which complete texels and texels fractions are covered by that pixel footprint. A set of un-normalized line equations characterizing a particular pixel footprint is used to determine whether each texel or subtexel in the vicinity of that pixel footprint is either enclosed or avoided by (i.e. inside or outside of) that projected pixel footprint.

Title: By the use of ECR-CVD system to deposite a dielectric with low dielectric constant
Inventor: JANG GUO-MING
IPC: H01L21/205
Filed: 1999-03-22
Granted: 2001-10-01
Abstract: Concurrently, how to maintain the desired properties for IMD applications (such as low mechanical stress, high thermal stability, and low moisture absorption) becomes another important subject of research. In the method, FxSiOy films were deposited in the electron cyclotron resonance (ECR) chemical vapor deposition system with SiH4, O2, and CF4 as reaction gases. The CF4, in contrast to SiF4 or FSi(OC2H5)3 used in other reports, is an indirect fluorinating source. The incorporation of fluorine comes from the unvolatile silicon fluoride, which has a similar formation plasma; mechanism as the etching of oxide by fluorocarbon therefore, the concentration and stability of fluorine in FxSiOy must strongly relate to the process temperature.

Filed: 1999-05-27
Granted: 2000-12-01
Abstract: A bias circuit is disclosed in which constant bias current is stably supplied regardless of changes in an operational voltage, temperature, and the process of a semiconductor, and bias current rapidly reaches a predetermined level when a semiconductor integrated circuit is transited from the power down state to the stand-by state or the active state. The bias circuit includes a first bias circuit, a second bias circuit, a current summation circuit, a first pull-down transistor, a second pull-down transistor, and an automatic pulse generator. The first bias circuit increases the current in accordance with an increase in temperature. The second bias circuit reduces the current in accordance with an increase in temperature. The current summation circuit mirrors the current of the first bias circuit in response to a signal of an output terminal of the first bias circuit and mirrors the current of the second bias circuit in response to a signal of an output terminal of the second bias circuit, and the mirrored currents are summed to output the first bias current. The first pull-down transistor reduces the voltage level of the output terminal of the first bias circuit in response to a startup pulse. The second pull-done transistor reduces the voltage level of the output terminal of the second bias circuit in response to the startup pulse. The automatic pulse generator automatically generates the startup pulse in response to a power down signal of the semiconductor integrated circuit.
