  • Trigger circuit unit for operating light emitting members such as leds or motors for use in personal ornament or toy in synchronization with music
    Patent number: 5402702
    Abstract: A trigger circuit unit including: a forward circuit block having a pickup circuit such as a microphone for picking up a signal of music so as to convert it into an electric signal; a filter circuit for selecting a portion of the band from a picked up audible frequency band; and a limit amplifier circuit mainly composed of an inverter operation logic IC for amplifying the selected electric signal having a portion of the band and transmitting an output having a predetermined amplitude; and a waveform conversion circuit block having a time constant circuit connected to the output of the forward circuit block and composed of a capacitor having one or more diodes connected in series and a resistor in order to prevent a backflow and to obtain a forward directional voltage difference, wherein analog pulse signals transmitted from the time constant circuit are caused to perform a Schmidt operation having a previously adjusted degree of hysteresis, wherein the rectangular pulse signals transmitted from the waveform co

  • Automobile transmission casing having reinforcement
    Patent number: 4435994
    Abstract: An automobile transmission including a peripheral wall having an inner surface comprised in a cross-section of a plurality of curved portions which are continuous in series with each other through inwardly projecting node portions. The configuration of the casing provides a structure of high rigidity so that it is effective to suppress the vibrations of the casing wall and consequently the noise caused by such vibrations. The casing wall is formed with brackets for supporting the reverse idle gear shaft in the vicinity of one of the node portions. This arrangement is also effective to suppress vibrations.
