  • Patent number: 6805219
    Abstract: An engine cover has a cover body having a through hole penetrating both sides of the cover body in an area opposed to a resonant space in which resonant sounds are generated. An opening of the through hole is covered with the sound absorbing member layer. Because a part of the resonant space is open, resonant sounds generated in the resonance space are decreased.

  • Patent number: 5497353
    Abstract: A multiport memory is provided which permits both random access and serial access. In order to reduce parasitic capacitance and improve operating speed, the serial input/output lines are each divided into two parts at their middle points. Sense amplifiers for the serial input/output lines are provided at upper and lower ends of the serial access memory elements to respectively amplify signals from the divided lines. Additional features are provided for improving both the serial and random operation. For example, during the serial read mode, the column selector for random access is simultaneously operated, and read data passing through the random access column selector is used as head data for the serial output operation to be delivered through the serial output circuit. Also, a serial selector can be controlled by a select signal formed by a Gray Code counter to improve operating speed.

  • Patent number: 5467315
    Abstract: The semiconductor memory is facilitated with control circuitry for effecting plural self-refresh modes having respectively different refresh periods. The plural self-refresh modes are typified by a PS (pseudo) refresh mode which is applied when the memory is in the nonselected state for a comparatively long period of time, such as in the state in which memory backup is being facilitated, and by a VS (virtual) refresh mode in which the refreshing operation of the memory cells is effected intermittently during the intervals of memory accessings. The pseudo refresh mode has a longer refresh time period than the virtual refresh mode. The control circuitry also has counter circuits for the generating of refresh address signals in accordance with a first timing signal indicative of a pseudo refresh mode and a second timing signal indicative of a virtual refresh mode, the latter timing signal being a higher frequency signal.
