The system offers high
efficiency, equivalent to that of
gas combined cycle power
generation systems, and is an
environmentally friendly
thermal power generation
system that does not emit CO2 into the atmosphere as it generates
power. We have recently carried out successful pressure fuel-
combustion on the gas turbine combustor, an essential component,
at the actual target pressure (300 atm), a big step towards realizing
the system.
Second-generation 19nm
process technology has allowed
us to realize a 64 gigabit NAND
flash memory with the world’s
smallest chip size (94.1mm2), in
collaboration with SanDisk
Corporation. In addition to reducing the chip size of the first-
generation 19nm chip by approximately 17%, we have achieved the
world's fastest-class write speed of 25Mbyte/second by using our
original high-speed writing circuit system.
We have developed a 150 kW
power converter for railway rolling
stock using our original 1.7kV- All-
SiC package. By increasing the
switching frequency from the
conventional 4.5kHz to the higher
16kHz, very high efficiency of 96% has been achieved at the rated
load and 40% reduction in volume and 60% reduction in weight
have been demonstrated. (This development was implemented
with assistance from NEDO’s “Strategic Innovation Program for
Energy Conservation Technologies.)
While avoiding any compromise
in captured image quality, we
have developed a Magnetic
Resonance Imaging (MRI)
system that achieves the
smallest installation space and
lowest power consumption in its class. This product solves
installation space and running cost issues that, until now, have
hindered the introduction of superconductive type MRI.
This order-made elevator offers enhanced energy
savings and safety features based on the concept
of safety, security, comfort and the environment.
We have also applied advanced technologies
employed in our standard elevator, the “SPACEL-
GR,” in order to enhance our product line-up with
excellent, energy-saving performance and safety
features. In Japan, these product lines won the
“Minister of Economy, Trade and Industry Award” at
the 10th Eco-Products Awards, and the “2013
Minister of Environment Recognition Award for
Global Warming Prevention Activities.”

Use of unique image recognition
technology has allowed us to
develop the world’s first
scanner for POS (point-of-sale)
systems that can identify
varieties of fruit and vegetables
that are simply held to the
scanner, removing the need to fix barcodes onto fruit and
vegetables.
