Patent number: 6958638Abstract: 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.Type: GrantFiled: October 9, 2003Date of Patent: October 25, 2005Assignee: Elpida Memory, Inc.Inventors: Tomoyuki Shibata, Kanji Oishi

Publication number: 20050064808Abstract: 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.Type: ApplicationFiled: September 24, 2004Publication date: March 24, 2005Inventors: Satoshi Ogawa, Tomoyuki Shibata

Publication number: 20050064807Abstract: 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.Type: ApplicationFiled: September 23, 2004Publication date: March 24, 2005Inventors: Satoshi Ogawa, Tomoyuki Shibata, Yoshiyuki Aoki
