  • Patent number: 6958638
    Abstract: A slew rate controlling system for output data is provided which is capable of improving an output data window even when change in a potential difference between a first power supply (VDD) to be used for outputting and a second power supply (VDDQ) to be used internally occurs. The slew rate controlling system is achieved by using a VDD-VDDQ potential difference detecting circuit to detect a decrease in a potential difference between the first power supply (VDD) and the second power supply (VDDQ) and to produce a first signal with specified timing and to detect an increase in a potential difference between the first power supply (VDD) and the second power supply (VDDQ) and to produce a second signal and by using a slew rate controlling circuit to exert control, when the first signal is significant, to enlarge a transition speed in a fall of output data and to exert control, when the second signal is significant, to enlarge the transition speed in a rise of output data and to produce output data.

  • Publication number: 20050098642
    Abstract: A mode selection unit, a blower unit and a temperature control unit are mounted on a cluster panel of a vehicle. The mode selection unit, the blower unit and the temperature control unit have a function of controlling the wind blow position, a function of controlling the wind blow rate and a function of controlling the wind blow temperature respectively, and are constituted by operating mechanisms mechanically separated from one another. Accordingly, the degree of freedom in the layout of the mode selection unit to the temperature control unit is improved so that it becomes easy to dispose them in accordance with the vehicle-side design.

  • Publication number: 20050064808
    Abstract: A plurality of click portions is formed integrally with a unit body. The click portions are arranged on a common circular track, and a dial is engaged with the click portions so as to be unstable and to be prevented from slipping off. Therefore, it is not necessary to provide a D spring for coupling the dial to a shaft so as to be unstable and to be prevented from slipping off. Consequently, it is possible to reduce the number of components and a cost.

  • Publication number: 20050064807
    Abstract: A gear portion is provided on the inner peripheral surface of a dial, and a large diameter portion of a main driving gear is mated with the gear portion. A driven gear is mated with a small diameter portion of the main driving gear, and the state of an air conditioner is switched based on the moving operation of a cable through the gear portion, the main driving gear and the driven gear in the rotating operation of the dial. With this structure, it is not necessary to provide a rotary shaft as a member for transmitting an operating force to the central part or the dial. Consequently, it is possible to maintain a space in the central part of the dial. Thus, restrictions can be decreased in the case in which a knob is to be arranged.
