Prevention of global warming is one of the greatest challenges facing the world. Being well aware of this, Daishinku has made considerable efforts to reduce operating power consumption of its products. Energy-efficient electronic components will reduce the power requirements of electric appliances, leading to significant savings in energy and subsequent reduction in CO2 emissions.
The driving voltage of our crystal oscillators has been reduced from 5 V to 1.8 V over the last 16 years from 1990 to 2006. Reduced driving voltage, combined with increased performance of oscillation circuit, has led to a reduction in electric power consumption of less than one thirty-fifth (1/35), from 0.075 W to 0.0021 W.
Power-saving efforts
As part of our resource-saving effort, we are constantly striving to reduce the size of the crystal products, because downsizing the products will reduce the material usage.
Daishinku introduced a surface-mounted crystal resonator, the DSX151 series, to the market in 1991. As a result of our continuous effort toward miniaturization, in 2005 the volume was reduced to approximately one-fiftieth (1/50), and the weight was reduced to approximately one-fortieth (1/40) of the original model. Smaller size leads to less weight, resulting in reduced material usage.
Changes in Volume and Weight with Increasing Miniaturization
Progress in Miniaturization by Year
Reducing the power consumption of electronic components contributes to saving
energy used by electrical appliances at homes and offices.
Part of the electricity we use is produced by a thermal power plant, which emits CO2 while generating electricity. Therefore, reducing
the power consumption of electronic components saves energy, leading to reduction in CO2 emissions.
In recent years, reduction in the use of hazardous chemical
substances has been strongly demanded, and laws and regulations relating to
hazardous substances have been strengthened both in Japan and abroad.
In Europe, new regulations regarding hazardous substances, such as the
WEEE Directive and RoHS Directive, have come into effect. With the RoHS
Directive taking effect in July 1, 2006, the use of lead, mercury, cadmium,
hexavalent chromium and brominated flame retardants (PBB, PBDE) is prohibited
in principle.
To comply with relevant laws and regulations and meet customer demands,
Daishinku has been working on developing and delivering RoHS-compliant
and lead-free products.
A European law that aims to reduce waste arising from electrical and electronic equipment (EEE) and to encourage reuse and recycling of EEE.
A European law that aims to protect human health through the restricted use of certain hazardous substances.
