    摘要: A method of manufacturing an electrically erasable semiconductor non-volatile memory device comprises forming a field insulating film on a surface of a semiconductor substrate having a first conductivity type. A gate insulating film is formed on the surface of the semiconductor substrate. Source and drain regions having a second conductivity type are formed in the surface of the semiconductor substrate in spaced-apart relationship with each other by introducing impurity ions having the second conductivity type into the semiconductor substrate with an acceleration energy sufficient to form a peak value of impurity concentration at a depth of more than approximately 500 .ANG. from the surface of the semiconductor substrate. The gate insulating film is then etched on the drain region to form a tunnel region having opposite sides connected to the field insulating film. Thereafter, a tunnel insulating film is formed on the tunnel region and a floating gate electrode is formed over the source region, the drain region and the semiconductor substrate through the gate insulating film and the tunnel insulating film. A control insulating film is then formed on the floating gate electrode, and a control gate electrode is formed over the floating gate electrode through the control insulating film.

    摘要: An low-power consumption integrated ring oscillator capable of stable operation throughout a wide voltage range without undergoing a large frequency change includes a first constant voltage generating circuit having an enhancement mode P-MOS transistor and a depletion mode N-MOS transistor and a second constant voltage generating circuit having a depletion mode N-MOS transistor and an enhancement mode N-MOS transistor. A first constant voltage generated by the first constant voltage circuit is applied to a gate electrode of a P-MOS transistor of transmission gates connected between respective cascaded inverters of the ring oscillator. A second constant voltage generated by the second constant voltage generating circuit is connected to the gate electrode of an N-MOS transistor of the transmission gates. By this construction, current consumption is reduced and battery lifetime can be increased. The boosting circuit for writing and erasing an EEPROM circuit may be formed with the low power ring oscillator.

    摘要: In a motor driven bell, a pair of cam members are operatively connected to a drive shaft of a motor. One of the cam members acts directly on a leaf spring for moving a hammer attached to the leaf spring generally in parallel relation to the axis of rotation of the cam member to thereby allow the hammer to strike against an associated gong. The other cam member is disposed generally parallel to the cam member so that the leaf spring interposes therebetween. Therefore, the cam members define an amplitude of the leaf spring, whereby the hammer is able to strike against the gong without mis-striking.
