Title: Liquid crystal display device, method for manufacturing the same and method for driving the same
Inventor: SUZUKI SHIGEYOSHI
IPC: G02F1/1334
Filed: 2000-05-17
Abstract: PROBLEM TO BE SOLVED: To provide a bright liquid crystal display device having high contrast in which a wide viewing angle and a narrow viewing angle can be easily switched from each other without increasing a complicated process such as photoresist process or without requiring accurate laminating techniques, and to provide a liquid crystal display device in which color irregularity is suppressed and deterioration by light is suppressed. SOLUTION: A color filter layer 105 consisting of at least one cholesteric liquid crystal layer is disposed in a liquid crystal cell. Thereby, the cell can be extremely easily positioned with wirings to drive the liquid crystal and a high opening rate can be obtained. A wide viewing angle and a narrow viewing angle can be easily switched from each other by attaching or detaching a scattering film 207 or by switching on or off a polymer dispersion liquid crystal 307. Since light can be turned on or off without controlling the alignment direction of the liquid crystal, the liquid crystal mode with fast switching can be easily used. Moreover, the light conventionally eliminated by a polarizing plate can be effectively used so that a bright display is possible. Since the color filter does not absorb light unlike a conventional filter, deterioration by light can be suppressed.

Title: Hybrid gas generator
Inventor: PEROTTO CHRISTIAN
IPC: B60R21/26
Filed: 2000-05-19
Abstract: PROBLEM TO BE SOLVED: To carry out mixing of gas at the outside of a storing chamber by making the gas in the gas storing chamber flow into a mixing chamber by movement of a piston owing to ignition of gunpowder, then making the gas flow out of a gas-flow- out-exit, then making combustion gas flow into the mixing chamber, mixing the combustion gas with the gas from the gas storing chamber and making the mixed gas flow out of the gas-flow-out-exit. SOLUTION: An internal partition 26 provided with a central opening 27 is provided at a downstream side of a gas-flow-out-exit 25 of a tube 2 and disposed in the inside of a diaphragm cap 28. Thereby, the tube 2 is divided into a combustion and mixing camber and a gas storing chamber 29. At the time of collision, a piston 31 is pushed forward by a high temperature gas generated by combustion of gunpowder and the diaphragm cap 28 is broken by a column 32 of the piston. Thereby, a low temperature gas in the storing chamber 29 is made to flow back to the combustion and mixing chamber from the central opening 27 and flow out of the gas-flow-out-exit 25 of the generator to develop air bag. At this time, the piston 31 is not engaged with a central opening 35.  Therefore the high temperature gas is made to flow into the mixing chamber and mixed with the low temperature gas and the resultant gas is made to flow out of the gas-flow-out-exit 25.

Title: Fuel injection control device for in-cylinder fuel injection engine
Inventor: KUDO MASAYA
IPC: F02M63/00
Filed: 2000-05-24
Abstract: PROBLEM TO BE SOLVED: To improve starting capability of an engine and exhaust gas emission, by properly setting a share ratio between the amount of the fuel to be injected into the inside of a cylinder and that to be injected into an air-intake pipe, taking into consideration the particulated condition of the fuel into the cylinder at the time of engine start. SOLUTION: When an engine is under control for start-up, the whole required amount of fuel injection for start-up is determined based on the temperature of the engine water (S1-S3), and then, referring to the share table based on the pressure of the high pressure fuel, an in-cylinder share of the fuel injection against the whole required amount of fuel injection, that is, a share ratio, is determined (S4-S5). Then, the amount of fuel to be injected into the inside of a cylinder through an in-cylinder injector is determined by multiplying the whole required amount of fuel injection by the share ratio, thereby setting the fuel injection pulse width (S6, S7).  Thereafter, the amount of fuel to be injected outside a cylinder through an outside-cylinder injector is determined by multiplying the whole required amount of fuel injection by the complement number of the share ratio (1-share ratio), thereby setting the fuel injection pulse width (S8, S9). This makes it possible to avoid supplying fuel at a time when the injection fuel in particulate form is of poor quality, thereby improving the starting capability of the engine.
