Title: Pressure accumulator fuel supply device
Inventor: TAMURA TATSUO
IPC: F02M37/10
Filed: 2000-01-31
Abstract: PROBLEM TO BE SOLVED: To obviate a sensor for detecting an OFF position of a pump motor. SOLUTION: A pressure accumulating chamber 15 is formed in a pressure accumulator 14 out of a movable member 23 and a cylindrical part 22. Fuel delivered from a fuel pump is supplied to the pressure accumulating chamber 15. The fuel in the pressure accumulating chamber 15 is pressurized by a nonlinear spring 25 to be supplied to a fuel injection valve. A motor current (a motor load) is detected when operating the pump motor. When the motor current exceeds a threshold value, it is judged that the movable member 23 descends up to a lower limit position, and the pump motor is stopped. When an increase in a pump motor current is not remarkable and does not reach the threshold value, the nonlinear spring 25 such as increasing the motor load is used on this side of the lower limit position. The fuel in the pressure accumulating chamber 15 is pressurized by this nonlinear spring 25.  When the movable member 23 ascends up to an upper limit position when stopping the motor, a magnetic flux of a magnet 26 is interlinked with a reed switch 28 to turn on the reed switch 28 to operate the pump motor to supply the fuel in the pressure accumulating chamber 15.

Title: Color picture tube having improved shadow mask/frame assembly support
Inventor: GOROG ISTWAN
IPC: H01J29/02
Filed: 2000-02-18
Abstract: PROBLEM TO BE SOLVED: To improve unsuitable impact load ability in a pipe with a specific aspect ratio, by providing an opening in a spring arranged at four corners of a panel, engaging it with a stud on the peripheral side wall to position a bracket. SOLUTION: This relates to a pipe with 16×9 aspect ratio. One leg portion 57 of a U-shaped bracket 50 is mounted to a peripheral frame 40, the other leg portion 58 has a slot 59 that opens through a bottom 60, and because of the opening, the bracket 50 can slide onto a stud 54 without using a device for pressing down the bracket. Therefore, a mask frame assembly can be inserted into or removed from the panel by pressing down four corner springs. Impact load durability in the X-direction is achieved, following a fact that the mask frame assembly deflects in the X-direction, by engaging the stud 54 with the side surface of the slot 59. Since the slot 59 having the opening in the bracket 50 is used, interference during insertion or removal of a shadow mask is prevented.
