Title: Gasoline direct injection engine
Inventor: TAKEDA MASAAKI
IPC: F02B23/10
Filed: 2000-09-19
Abstract: PROBLEM TO BE SOLVED: To provide a gasoline direct injection engine constituted so that ignition stability is prevented to be impaired. SOLUTION: This gasoline direct injection engine is equipped with a combustion chamber 1 formed between a cylinder head CH and a top part of a piston 5, a nozzle 2 for injecting fuel to the combustion chamber, a cavity 6 hollowly provided on the top part of the piston, an electrode 3 of an ignition plug located to face the cavity, and a protruding surface 7 formed around the cavity on the top surface of the piston. An inclining surface has a smaller angle than an angle of a ceiling surface of the combustion chamber with respect to a plane lying at right angles to a cylinder axis. Thus, the change of a space between the protruding surface and the ceiling surface of the combustion chamber can be moderated. Therefore, direct flow of swirl flow into the cavity is restrained and air-fuel mixture around the ignition plug is maintained.  Thus, the ignition stability is prevented to be impaired.

Title: Dimmer and image pickup device
Inventor: UKO TORU
IPC: G03B9/02
Filed: 2000-10-19
Abstract: PROBLEM TO BE SOLVED: To provide a dimmer which can improve the transmittance for light, which enhances the contrast ratio and which can maintain the light quantity uniform. SOLUTION: This dimmer consists of a GH(guest-host) cell 12 and a polarizing plate 11. As for the host material 13, a negative type liquid crystal having negative dielectric anisotropy (Δε) is used, while a positive dye showing dichroism is used as the guest material 4. The polarizing plate 11 is disposed on the incident light side of the GH cell 12. The polarizing plate 11 is stuck to an iris vane 18 and can be inserted into or removed from the effective optical path of light incident on the GH cell 12. When the iris vanes 18, 19 are driven by a motor to overlap with each other, the polarizing plate 11 is inserted into the effective optical path 20 to cover the aperture 22. When the brightness of the objective body increases, light is controlled by absorbing the light by the GH cell 12.  Since the polarizing plate 11 can be removed from the effective optical path 20 of light, the light is not absorbed by the polarizing plate 11, which increases the maximum transmittance of the dimmer.
