Some examples of material reduction design are shown below. Please refer product specifications of each product if you would like to know which examples are adopted by that product.

Light weight and compact design
Realizing a case of 0.4mm thick |
| Metal retains strength even when formed thin, but it is still relatively heavy and not a good material for portable products in general. We use magnesium alloy for our PCs. Magnesium is a metal, but light one, and it brings PC case of 0.4mm thinness with acceptable hardness. Such thinness is achieved by adopting technologies called "film gate" (a thin, wide opening for pouring magnesium) and vacuum casting (casting in vacuumed condition) in the magnesium die-casting process. |

Reduction of waste
|
In manufacturing printed circuit boards, residual materials cannot be avoided. We are making efforts to minimize them. This example shows a case where we succeeded in a 50% reduction compared to the previous board through changes in the board layout and improvement of production facilities.

Lengthening product life
Protect Hard Disk Drives from accidental shock |
The hard disk drive is a precise electro-mechanical device, and one of the most delicate parts of the PC. We have introduced a three-dimensional acceleration sensor for monitoring the position of a notebook PC. Inclination of the notebook PC that could lead to damage to the hard disk drive is calculated, and if it is reached - if the PC falls from a desk for example - the read/write head is retracted from the surface of the disk, avoiding damage to the disk or the head.

Adoption of SSD (Solid State Drive) |
Latest semiconductor technology makes it possible to replace a HDD (hard
disk drive) with a flash memory module which has big capacity comparable
with HDD and feature of non-volatile like HDD. This semiconductor memory
is called SSD (Solid State Drive) .
To use SSD in place of HDD brings many excellent features, not only fast
access time but also the following merits for environment: |
- Strong against mechanical shock (no mechanical structure)
- Small size and light weight
- Low power consumption (no mechanical movement like motor)
- Best use of power management function (quick starting up of operating system)
- Low sound noise(no mechanical movement)

Toshiba Health Monitor Symptom monitoring for failure prevention |
| Toshiba Health Monitor is a system consists of hardware, BIOS and utility software. It monitors various points of a PC such as power management setting, temperature of a CPU and a battery, and current capacity of a battery. When it detects status or events which may possibly result in failure, it will raise an alarm to the user. This system is helpful to prevent trouble or damage of the PC. |

Spill resistant keyboard
|
| A spill resistant keyboard has a tray at the bottom of the keyboard. The tray can hold a certain amount of water and will resist water to penetrate into the PC through the keyboard. This function is effective to avoid immediate damage to the PC in such case that a user unintentionally spill water on the keyboard. |

|
Honeycombed rib structure for PC case
|
| Toshiba note PC introduced honeycombed rib structure for the thin case made of magnesium alloy in order to ensure its strength. The rib in the shape of honeycomb realized 0.4 mm thick with required strength. |

Reduction of packaging materials
Small packaging box |
| We reduced packaging materials by miniaturization of a
packaging box. The small size and light weight packaging box also contributes
to reduction of energy used for product transportation. It is big effect because
products are shipped to many countries world wide. |

Adoption of materials of lower environmental impact
Use of recycled plastic |
To use plastic recycled from various used products contributes to reduction
of waste and effective use of material resource. Every Toshiba note PC
is guided to use recycled plastic.
|
Use of bio plastic |
Toshiba promotes use of bio plastic, whose life cycle CO2 emission is zero and called carbon neutral . Example shown here is a tape for packaging that contains bio plastic.
