In the development process of the manufactured products, unifying all items of information which relate to design development, the information system which it manages, assures shortening the improvement of efficiency and period of process. Function such as cooperation with the management of the data regarding the design which consists of plan data such as CAD data and the document data of the specification and the like and management and the buying materials system of the constitution data of the part which forms the product, grasp of schedule of design production and the work flow management which assures improvement of efficiency being center, it is constituted.

At one of types of thin-shaped display unit, applying high voltage in the inert gas of the high pressure which is enclosed between the plate glasses those which it radiates. Principle was discovered by the American Illinois university to 1966, after that bet on the eighties time and was utilized as the display and the like of the computer, but excessively it does not spread, making the most of the sale of the plasma television by the pioneer 1997, presently it has spread as a thin-shaped large picture television.

Principle of indication being the same as the fluorescent light, encloses the vapor of high pressure of inert gas family element such as helium and neon between 2 glass which formed the electrode on the surface applies voltage there and radiates the gas by generating the ultraviolet ray. In comparison with other system such as liquid crystal, speed of response is fast, contrast is high, angle of visibility is wide, a feature that is, enlargement is easy, the thin-shaped television of the large picture (the plasma television) as to be wide has spread. But, weight of the device to be heavy miniaturization being difficult, also the Kousei small conversion which raises pixel density is difficult, there is also a weak point that does not face to the use of display of the personal computer and the screen etc of the portable equipment, electric power consumption to be large also heat generation is extreme, with such use liquid crystal display has spread.

In the display PDP (plasma display) the thin-shaped TV set which is used. Spread is advanced quickly as the thin-shaped large picture television which is substituted to the picture tube television.

As for PDP applying high voltage in the inert gas of the high pressure which is enclosed between 2 plate glasses with the display which it radiates, the principle was discovered by the American Illinois university to 1966. As for the PDP television for national welfare the pioneer succeeds in commercialization for the first time in 1997, to be wide has spread ever since, with the liquid crystal powerful of the thin-shaped television as a formula on the one hand.

PDP speed of response is fast, contrast is high, angle of visibility is wide, but the feature which is suited for the large picture television that enlargement is easy, is had, because on the other hand, weight of the device to be heavy miniaturization is difficult, as for the small-sized thin-shaped television the liquid crystal television is many. In general, 37 types as for small size the liquid crystal television, the living amount wound, PDP television we do the large size in boundary, as for the liquid crystal television as for the PDP television aiming toward small-sized product, improvement is continued larger-sized product.

The software where the production person abandons copyright. The user freely can do correction and the redistribution etc for the third party. With the Japanese degrees of laws because copyright cannot be abandoned, PDS in strict sense does not exist in Japan. As for the generally known free software, because while the right the production person regarding the software is kept, freedom of correction and redistribution etc is recognized in the user, PDS is the concept which differs.
