This one is a crystal. It's used for setting a frequency from its natural vibration.
 


Yes - it says "TX1" on the board. I think you will spot "L2" (i.e. an inductor) on the component at the back of the picture - is that the one you asked about in a previous post?
 


This is remote control circuit an the series is SJC27145A What is the symbol?
