  • Method of manufacturing a nonvolatile semiconductor memory device, and a nonvolatile semiconductor memory device
    Patent number: 7371631
    Abstract: For enhancing the high performance of a non-volatile semiconductor memory device having an MONOS type transistor, a non-volatile semiconductor memory device is provided with MONOS type transistors having improved performance in which the memory cell of an MONOS non-volatile memory comprises a control transistor and a memory transistor. A control gate of the control transistor comprises an n-type polycrystal silicon film and is formed over a gate insulative film comprising a silicon oxide film. A memory gate of the memory transistor comprises an n-type polycrystal silicon film and is disposed on one of the side walls of the control gate. The memory gate comprises a doped polycrystal silicon film with a sheet resistance lower than that of the control gate comprising a polycrystal silicon film formed by ion implantation of impurities to the undoped silicon film.

  • Audio device maintenance support apparatus
    Publication number: 20070025558
    Abstract: An audio device maintenance support apparatus which is capable of notifying a user in advance of timing for loudspeaker unit replacement. An audio signal is input via a signal input section. An amplifier amplifies the input audio signal. A loudspeaker unit outputs the audio signal amplified by the amplifier, as sound. An integral value calculating section calculates an integral value of the signal level of the audio signal supplied to the loudspeaker unit via the amplifier with respect to a supply time length of the audio signal. When the calculated integral value exceeds a predetermined threshold value, a notification control section gives a message recommending maintenance of the loudspeaker unit.

  • Joint structure of electric wire, stator of rotary electric machine, method for manufacturing the same
    Publication number: 20060267440
    Abstract: When electric wires (joint conductors) are disposed adjacent each other in a peeled state of coatings, a gap corresponding to the total thickness of both conductors' insulating films as skin layers is formed between end joined face portions of the conductors. The gap becomes larger because the conductors are tapered. Therefore, the adhesion between both conductors is impaired, with a consequent fear of occurrence of joining imperfection. In opposed joined face portions of electric wires (joint conductors), the conductors are deformed from the tips of their axes to the joined face side in such a manner that exposed portions at the tips of the conductors and insulating film faces located in the vicinity thereof are flush with each other or the exposed portions are projected.
