A pneumatic tire comprises a tread portion having a plurality of slant grooves, in which each slant groove has a steeply slant groove portion and a gently slant groove portion, and the steeply slant groove portion comprises a pseudo-land part of a given shape, and can improve a drainage performance without sacrificing the other tire performances. The method on a wireless device includes establishing an audio connection with a second device and providing an interface for a user for sending data to the second device. By connecting the output terminal of the NO to the high-potential-side of a high-voltage circuit disposed separately and the negative electrode of a control power supply to the low-potential-side of the high-voltage circuit in the state, in which the NO is OFF, a desired high voltage is applied between the collector and emitter of the NO. The molding machine is electrically operated to control the movement of a movable molding portion when closed upon a stationary molding portion. The inventive VSA system includes a microprocessor-based controller for automatic operation, which controller interfaces with PC operated quilting programs that drive powered XY carriage systems to allow sewing of quilting patterns much larger than the throat depth of conventional sewing machines.
