Abstract: An odor removing system allows a user to remove waste gases and unpleasant odor emanating during or after the discharge of human waste. The system includes a seat with one or more inlets and vent slots to guide waste gases from a toilet bowl into an odor canal. Seat hinges to which the seat is pivotally attached, allows various ranges of seat movement. An odor canal attached to the seat that siphons waste gases and unpleasant odor introduced by the seat vent slots and transfers waste gases and unpleasant odor to an odor channel, attached to the odor canal. The odor channel disposes the waste gases and unpleasant odor to a pipe, a ventilation system or outside.

Abstract: Provided is a spectrophotometer using medium energy ion. The spectrophotometer using medium energy ion is configured to include: an ion source 10 generating ions; a collimator 20 collimating the ions as a parallel beam; an accelerator 30 accelerating the parallel beam; an ion beam pulse generator 40 pulsing the accelerated ion beam; a focusing objective 50 focusing the pulsed ion beam on a specimen 1; a detector 60 detecting a spectroscopic signal of scattered ion from a specimen 1; and a data analyzer 70 analyzing and processing the spectroscopic signal detected by the detector 60.

Abstract: A novel organometallic compound of formula M[(.mu.-OR').sub.2 M'R.sub.2 ].sub.2 can be vaporized at a low temperature and advantageously employed in the CVD of a heterometallic oxide film of the MM'.sub.2 O.sub.4 type, wherein M is a divalent element such as Be, Mg, Zn or Cd; M' is a Group 13 element such as Al or Ga; and R and R' are each independently a C.sub.1-10 alkyl group, with the proviso that if M is Mg, M' is not Al.
