Power consumption of electronic devices such as PCs, cell
phones and flat-screen televisions can be lowered by reducing the power
consumption of crystal products used in these devices. Efforts to promote
energy-efficient products helps reduce the amount of energy–such as petroleum
and coals–used for power generation, as well as CO2
emissions, a major cause of global warming.
Our DSO221SR crystal oscillator,
for example, has achieved a driving voltage of 1.8 V, about one-third that of
the DSO751SB, and has reduced electric power consumption to less than 1/35, from
75 mW to just 2.1 mW.
We will continue our efforts to develop products with
lower driving voltage.

Increasing Miniaturization

Products

For each crystal product, we examine its impact on the environment in the
design stage to ensure no hazardous substances are contained in the materials.
We also evaluate chemicals used in the product before starting factory
production using in-house analyzers.

Lead-free Our efforts to reduce the use of lead, a substance with serious impacts on the ecosystem, started in 2002. Products with lead terminals such as AT-49, SMD-49 and HC-49/U are now completely lead-free except for some special products. DT-26/38/261/381, used for clocks, etc., are now produced using lead-free external plating and internal solder. ◆ Halogen-free Halides such as chlorine, bromine and fluorine generate dioxins and other highly toxic substances into the air when incinerated. Paying attention to the hazards of halides on the environment, we have been examining and assessing potential alternative materials. |

Environmental laws and
regulations, established mainly in Europe, have been increasingly enhanced for
electrical/electronic devices and automobiles. China, a country called the
world's factory, implemented the China RoHS in 2007, demonstrating its strong
commitment to environmental conservation. Because our crystal products are
largely used in various electrical/ electronic devices as well as in
automobiles, which are being increasingly computerized, we are actively
promoting compliance with these laws and regulations.
◆ WEEE(Waste
Electrical and Electronic Equipment) Directive
A directive concerning
disposal and recycling of electrical and electronic equipment (EEE). Indications
shall be provided for target products to be collected and recycled, in order to
promote reduction of impacts on the environment.
◆ RoHS(Restriction on
the Use of Certain Hazardous Substances in Electrical and Electronic Equipment)
Directive
This directive aims to ensure that lead, mercury, hexavalent
chromium, cadmium, brominated flame retardants (PBB, PBDE) are not contained in
electrical and electronic equipment. Though there are some exceptions, it
inhibits the use of these substances in order to promote reduction of
environmentally hazardous substances.
◆ ELV (End-of-Life Vehicle)
Directive
A directive concerning disposal and recycling of automobiles.
Automobile components should not contain lead, mercury, hexavalent chromium and
cadmium.
◆ China RoHS(Management Methods on the Prevention and Control
of Pollution Caused by Electronic Information Products)
Substances specified
by the Chinese government are added to the restricted substances under the RoHS
Directive. After announcement of the specified substances to be restricted in
the first stage, a compulsory registration system was adopted. The world now
awaits the second stage implementation.
