    Abstract: A color cathode ray tube includes in combination an in-line type electron gun assembly and a dot type phosphor screen, wherein an outer panel surface is made substantially flat, an inner surface is curved and a shadow mask has round apertures or holes while having a curved shape with a convex form as projected toward the panel. The display tube is featured in that the shadow mask holes have a horizontal direction pitch Ph and vertical direction pitch Pv, that the horizontal pitch Ph has a value at terminate ends of a minor axis of the shadow mask, which value is at least 5% greater than a pitch value at the center part of the shadow mask, and that a Ph/Pv value at the shadow mask minor axis ends is greater than that at the shadow mask center. With such an arrangement, it is possible to increase the mechanical strength at a part adjacent to the shadow mask minor axis in particular.

  • Patent number: 6537178
    Abstract: After an engine (1) has started, a controller (6) starts determining whether lockup should be prohibited or permitted based on the cooling water temperature of an engine (1) or the oil temperature of a transmission (2). Once it has been determined that lockup should be permitted, the controller (6) stops determining whether lockup should be prohibited or permitted until the next time the engine (1) is started. In this way, once the conditions for determining that lockup should be permitted hold, lockup prohibition or permission based on the engine cooling water temperature or transmission oil temperature is no longer determined, so repeat engaging and disengaging of the lockup clutch (5) due to fluctuations of engine cooling water temperature or transmission oil temperature, is prevented.

  • Patent number: 6505139
    Abstract: The vehicle comprises a continuously variable transmission and traction control system (TCS) which controls a driving force. When the TCS is not operating, a controller computes a final target ratio based on a sensor detected vehicle speed. When the TCS is operating, the final target ratio is computed based on an estimated vehicle speed, and the final target ratio is limited by a speed ratio upper limiting value computed based on the sensor detected vehicle speed. The controller controls a speed change actuator so that a real speed ratio approaches the final target ratio.

  • Patent number: 6398691
    Abstract: A speed change control device for an automatic transmission wherein the speed ratio is automatically varied according to a running state when an automatic shift mode is selected, and the speed ratio is varied based on a manual operation when the manual shift mode is selected. When there is a change-over from the automatic shift mode to the manual shift mode, a speed ratio immediately after the change-over is set to a speed ratio such that a transmission input rotation speed after the change-over increases by at least a predetermined rotation speed compared to the transmission input rotation speed before the change-over. In this way, the effectiveness of engine braking is enhanced immediately after a change-over to the manual shift mode, or a downshift for acceleration can be definitively performed.

  • Patent number: 6373202
    Abstract: In a color cathode ray tube having a flat panel exterior surface, the screen distortion and the convergence give rise to problems. To overcome these problems, by arranging bar magnets in such a manner that they are disposed parallel to a screen and are shifted from upper and lower ends of a horizontal deflection coil of a deflection yoke by not less than 10 mm in the direction perpendicular to a tube axis, the distortion of the screen and the characteristics of the convergence can be simultaneously improved.

  • Patent number: 6370468
    Abstract: When a slip control system starts operating, a vehicle speed VSP used for speed change control is simultaneously changed over from a sensor detected vehicle speed VSPSEN to an estimated vehicle speed VSPFL. On the other hand, when the slip control system has stopped, it is first determined whether a speed ratio variation amount, due to the change-over of the vehicle speed used for speed change control from the estimated vehicle speed VSPFL to the sensor detected vehicle speed VSPSEN, is less than a permissible amount. When it is determined that the speed ratio variation amount is smaller than the permissible amount, the vehicle speed used for speed change control is changed over from the estimated vehicle speed VSPFL to the sensor detected vehicle speed VSPSEN. By performing this change-over, a sharp variation of the vehicle speed used for speed change control is suppressed, and a sharp variation of the speed ratio leading to shocks or slipping is suppressed.
