The Mitsubishi team (STUDY) the problem for weeks when they (MAKE) a major breakthrough.
Mitsubishi (NOT MANAGE YET) to insert a biological diode into a circuit.
As soon as they (CONNECT) the bio-diode to an electronic component, Mitsubishi (MARKET) this product. Perhaps next month.
Soon, traditional silicon chips (REACH ) the limits of miniaturisation.
The team (WORK) on the bio-diode since they (DISCOVER) the unusual properties of flavocytochrome.
Computers (GET) increasingly sophisticated. My PC (BE) obsolete by next year.
A power-cut (OCCUR) while Ueyama (USE) the electronic microscope.
A silicon chip (STORE) and (PROCESS) data.
At the moment, Mitsubishi (DEVELOP) microchips which USE 0.25-micrometre components.
The Japanese Ministry of Industry (ALREADY FUND) previous projects for Mitsubishi when it (SUBSIDISE) the development of the bio-diode.
