摘要:
A narrow neck bottle is washed and rinsed by a method comprising the steps of supporting the bottle in an upside down position, injecting water containing air bubbles, into the bottle through a tube extending through the narrow neck of the bottle, accumulating air released from the poured water in an upper space in the bottle and expelling air and water remaining in the bottle by the accumulated air. Apparatus for carrying out this method comprises an aspirator installed such that its discharge pipe is directed upwardly, and connected to the discharge pipe, and a support for supporting the narrow neck bottle such that when supported by the support, the narrow neck of the bottle engages against the tube and that a gap is formed between the inner bottom surface of the bottle and the free end of the tube.

There is disclosed an organic field effect element having an large ON/OFF current ratio. The organic field effect element includes a source electrode and a drain electrode formed separately to each other, a first organic layer constituting a channel between the source and drain electrodes, a second organic layer formed to be adjacent to the channel and having a carrier concentration different from that of the first organic layer, and a gate electrode formed to be opposite to the channel through the second organic layer. Carriers are transferred between the second and first organic layers in response to a voltage applied to the gate electrode to change an electrical conductivity of the channel.

摘要:
A refractive index variable element has a structure including a solid matrix, and one or more types of quantum dots dispersed in the solid matrix and having discrete occupied and unoccupied electron energy levels. The quantum dots perform a function of generating a pair of positive and negative charges upon irradiation with light, a function of trapping a positive charge, and a function of trapping a negative charge. The quantum dots performing the function of trapping a negative charge are selected from the group consisting of a combination of a negatively charged accepter and a positively charged atom, where the outermost electron shell of the positively charged atom is fully filled with electrons so that an additional electron occupies an upper different shell orbital when receives an electron, a metal chelate complex, and metallocene and derivatives thereof.
