Title: Movable cowl cover for vehicle
Inventor: SUMI HIDEKI
IPC: B60S1/04
Filed: 1988-03-16
Abstract: PURPOSE:To prevent the reduction of the cleaning faculty by reducing the wind speed on a front window and suppressing the floating-up of a wiper which is caused by the increase of wind speed by allowing the opening of a cowl cover to be varied in accordance with the car speed. CONSTITUTION:A cowl cover 4 which is opened in harmonization with the start of a wiper is constituted so that a pinion 10 revolved by a control motor pushes up a rack bar 11 and a shaft fitting 14 is pushed up and revolves around a shaft fitting 8 as center. The opening/closing of the cowl cover 4 is controlled by a controller 15 which carries out electronic control by receiving a signal from a car speed sensor 16 and an opening degree sensor 17 for the cowl cover 4. Then, the wind speed on a front window 2 is reduced by largely opening the cowl cover 4 in high speed traveling and changing the direction of air stream upwardly so that the air flow does not strongly collide with the front window 2 directly, and the floating-up of the wiper is prevented, and the reduction of the cleaning function can be prevented.

Title: Erasing method for non-volatile semiconductor memory
Inventor: MATSUO MAKOTO
IPC: G11C16/14
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To improve reliability by suppressing deterioration in a repeating characteristic of writing/erasing in a non-volatile semiconductor memory in which a drain is made a floating state, negative voltage is applied to a control gate, and positive voltage is applied to a source. SOLUTION: Such a pulse is used that applied voltage at an initial time of erasing is low, after that, applied voltage is gradually increased as a pulse applied to a control gate or a source at the time of erasing operation. For example, as shown in the figure, a drain is made a floating state at the time of erasing, a constant voltage pulse of '4V' is applied to a source, on the other hand, such a pulse is used that applied voltage at an initial time of erasing is low, after that, applied voltage is gradually increased as a pulse applied to a control gate. Thereby, an electric field applied to a tunnel oxide film at the time of erasing can be suppressed to a lower level than that in the case of using a constant voltage pulse. Therefore, electron trap occurring in a tunnel oxide film is suppressed by high electric field stress, and deterioration of a repeating characteristic of writing/erasing caused by electron trap can be suppressed.
