Title: Inter-vehicle distance estimating device
Inventor: YAMAMURA TOSHIHIRO
IPC: G06T7/60
Filed: 2000-10-06
Abstract: PROBLEM TO BE SOLVED: To estimate an accurate inter-vehicle distance on the basis of an image obtained via a camera in a vehicle mounted with a radar and the camera. SOLUTION: If a radar-based inter-vehicle distance DL falls below a prescribed value L1, the lower end of the rear bumper of the preceding vehicle in a camera image is detected as a horizontal edge HE, whose y-coordinate YE and infinite point y-coordinate Y0 are stored in conjunction with the inter- vehicle distance DL at the moment (= output inter-vehicle distance Dout). If the radar-based inter-vehicle distance DL falls below a prescribed value L2, the preceding output inter-vehicle distance Dout and the latest horizontal edge y-coordinate YE and infinite point y-coordinate Y0 are used to compute an estimate inter-vehicle distance DC. A pitch angle detection window is set on each side of the horizontal edge HE, and on the basis of the vertical slippage between horizontal density averages, a pitch angle change is computed to correct the infinite point y-coordinate Y0.

Abstract: PROBLEM TO BE SOLVED: To provide a polarizing plate less liable to cause light leakage even when a polarizer with cross nicol arrangement is obliquely seen from a direction deviated from its optical axis, also less liable to cause coloration due to wavelength dispersion and excellent in neutrality. SOLUTION: The polarizing plate is obtained by bonding a transparent protective film (2) comprising two phase contrast films (21, 22) having 190-320 nm intrasurface phase contrast under light of 550 nm wavelength to at least one face of a polarizer (1) in such a way that the delay phase axes of the phase contrast films are made parallel to the absorption axis of the polarizer. When intrasurface refractive indexes are represented by nx and ny, refractive index in thickness direction is represented by nz and the relations of nx>ny and Nz=(nx-nz)/(nx-ny) are satisfied, the two phase contrast films are a combination of films whose Nz values are 0.8-0.95 and 0.55-0.7, respectively.  The polarizing plate has compensatory action by which optical axes (e.g. delay phase axes) of the phase contrast films forming the trasparent protective film shift in accordance with a change of the visual angle to offset a shift of an optical axis (e.g. absorption axis) of the polarizer.

Title: Vehicular liquid storage container
Inventor: TAKEUCHI KAZUHIRO
IPC: F01P11/18
Filed: 2000-10-31
Abstract: PROBLEM TO BE SOLVED: To solve the problem that the apparent plate thickness of a low- transparency resin container increases if a reserve tank for storing cooling water can be seen only slantingly from above because of its vehicle-mounted position, and the transparency of the low-transparency resin container further decreases to make the quantity of the internal cooling water hard to recognize visually. SOLUTION: A visible portion 4 of a reserve tank has vertically repeatedly inclined corrugations. Inclined plates forming the corrugations on one slant are sight line-perpendicular plates 4a substantially perpendicular to a visual direction A, and when seen slantingly from above, the apparent plate thickness of the sight line-perpendicular plates 4a substantially becomes a minimum. Even if the reserve tank can be seen only slantingly from above because of vehicle-mounting limitations, the apparent plate thickness of the sight line- perpendicular plates 4a is not increased when seen in the visual direction, so that the quantity of internally stored cooling water can be easy to recognize visually via the sight line-perpendicular plates 4a.
