    摘要: 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.

    摘要: 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. Further features included a redundancy system for relief of defective bits, the use of common bit lines to improve integration density and an improved refreshing arrangement to reduce power consumption during the refresh mode.

    摘要: In the past, it has been a problem in integrated circuits using MOSFETs that the gate insulating film of a transmission gate MOSFET is broken down when an abnormally high voltage such as is caused by frictional static electricity is applied to its drain region. This breakdown of the gate insulating film cannot be prevented merely by limiting the voltage level applied to the drain region to a level below the breakdown withstand voltage of the gate insulating film. The reason for this is that even with such voltage limiting, the breakdown of the gate insulating film can still occur when local heating is generated by a relatively large breakdown current flowing through the drain junction. To prevent such a breakdown of the gate insulating film, therefore, a resistance element for limiting the breakdown current is connected in series with the drain region of the transmission gate MOSFET.

    摘要: A mounting structure for an engine cover includes: a protruded member which has a neck and a head with a larger diameter than the neck; and a recessed member which has an external circumferential surface small diameter section to be locked to a mounting hole of a mounting seat arranged so as to be opposed to the protruded member, and a concave holding the head of the press-fit protruded member. In the protruded member, at least a portion surrounding the concave is formed solid. The head is arranged closer to a rear surface of the engine cover than the mounting hole. A compression space, which is compressed in the case in which a collision load equal to or larger than a predetermined value is applied in a front and rear direction of the engine cover, is defined between the recessed member and the rear surface of the engine cover.
