摘要:
A component management system comprises a storage device for storing a plurality of components related to hardware and firmware which are necessary for the development, manufacture, inspection, and the like of a product as a component data base. The hardware and the firmware constituting the product are at the same management level. The system further comprises a management server for managing the component data base. A reception-related client is connected to the management server via a network N and it can take out a predetermined component from the component data base via the network N.

The invention provides an acoustic cooling system with a noise reduction function of the type wherein a driving condition of a sound source used in the acoustic cooling system is controlled to compress coolant by a sound wave and a cooling object is cooled making use of an endothermic action of the coolant when the compressed coolant is expanded and which can reduce noise produced from the sound source effectively. To this end, the acoustic cooling system forwards cancellation sound having a characteristic capable of offsetting or cancelling the noise originating from the sound source and includes a cancellation signal production element for producing, in accordance with a driving control signal produced by a sound source control element, a cancellation signal having a characteristic capable of cancelling the noise produced as the sound source is driven, a cancellation signal level adjustment element for adjusting the signal level of the cancellation signal in accordance with the driving control signal, and a cancellation sound outputting element for converting the cancellation signal having the adjusted signal level into a sound wave and outputting the sound wave as the cancellation sound for the noise.

A client terminal in the information collecting apparatus collects a Web information described in hyper text language form a Web server terminal via the Internet. This client terminal starts up a browser and previously sets a flag at a target data cell in the collected Web information. The client terminal first automatically collects the latest Web information when the time in the timer reaches a prespecified time by utilizing a program for data transfer without starting up the browser, and then collects a latest data cell corresponding to the data cell for which a flag has been set.

A system of copying a digital document easily maintains the security of the contents of the screen display of, for example, a Web page of the Internet displayed on, for example, a display unit. Tag information indicating the prevention of copying of a screen is included in the hypertext in which a document from a server is described. On the client side, browsing software for actually performing a screen-display using the document interprets the tag information in the hypertext, and prevents making of a copy of the screen when a user issues a request to make a copy of the screen.

A coefficient updating method stops updating filter coefficients for a plurality of adaptive filters when a convergence condition is achieved. Active noise control within a system simulates an original noise signal with a simulated noise signal which is equal and opposite to the original noise signal. To detect feedback in such a system, a reference signal or "white noise" is generated by a speaker, transmitted through the system and received by a microphone. Coefficients of multiple filters such as an anti-feedback filter, a C filter, and a noise control filter are then updated to minimize adverse parameters such as original noise and feedback. Coefficient updating of the adaptive filters is stopped when a minimum average value is reached.
