IPC: B62D25/04
Filed: 1993-12-30
Abstract: PURPOSE:To reduce pressure resistance in traveling of an open car in its open state, by providing in the cabin a supply port for supplying air in its open traveling. CONSTITUTION:A groove 3 is notched in the upper end of the front header 2 of an open car at the center in the car width direction, the rear side aperture of the groove 3 constitutes a blow-off port 4 as an air supply port, and the front side aperture of the groove 3 constitutes an air introduction port 5. In the case of traveling in its open state, an air blow from the front direction separates at the upper end of the front header 2 so as to form an eddy in the inside of a cabin 6 and reduce pressure in the inside of the cabin 6, however, the air flow flows in the car body rear direction through the groove 3 and flows to left/right rear flow (eddy flow) of low pressure. Pressure reduction in the cabin 6 is suppressed thus pressure difference between the front and the rear of the front window glass 13 is reduced so as to a pressure resistance.

Title: Sidewall charge-coupled image sensing element and manufacture thereof
Inventor: HONNSAMU FUIRITSUPU UONGU
IPC: H01L21/763
Filed: 1991-12-13
Abstract: PURPOSE: To provide a charge coupled imaging device including a plurality of trenches in the surface of a silicon substrate for isolating adjacent rows in a CCD element. CONSTITUTION: A plurality of surface electrodes are arranged on the surface of a charge coupled device extending in the direction perpendicular to an isolation trench 10 and the electrode transfers clock control charges between adjacent cells in each row of the charge coupled device. A CCD cell is formed on a silicon ridge 12 which is formed between the isolation trenches 10. This structure maximizes the three-dimensional area of the CCD cell while facilitating transfer of charge along the side wall thereof. Layout of the side wall CCD cell having trench isolation is similar to that of conventional two-dimensional CCD cell but the charge capacity per CCD cell is increased because the three-dimensional area of the CCD cell is large. Increase of charge capacity means a significantly higher SN ratio and thereby a significantly wider dynamic range.
