摘要： PROBLEM TO BE SOLVED: To make a DC component of a wave form of voltage applied to a cathode tube zero on the whole based on 0 V. SOLUTION: A circuit permitting a combination of changing the position of an earthing tap of a step-up transformer and changing-over a wave form of AC voltage applied to an electrode on one side of a cathode tube to a full wave form or a half wave form is added. A power DC/AC inverter for lighting of a back light is adapted to apply AC voltage to one electrode of the cathode tube and apply AC voltage of an antiphase to the other electrode.

摘要： PURPOSE: To make depression force at the time of the key input of an operator appropriate. CONSTITUTION: In an equipment provided with a keyboard, a pressure sensor 2 detects the depression force corresponding to the depression force of a key top 1 and it is connected through an A/D converter 3 to a microcomputer 4 for judging the strength and weakness of the pressing force. A ROM 5 is connected to the microcomputer 4 and the strength/weakness judged result of the depression force is transmitted to a voice synthesis circuit 7 by it. The voice synthesis circuit 7 outputs the voice signal of either strength or weakness and voice is outputted from a speaker 9 through an AMP 8. Thus, by informing the sufficiency/insufficiency of the key depression force of the operator by the voice, protection from destruction is performed, a serve life is prolonged and key non-input is prevented.

摘要： PROBLEM TO BE SOLVED: To provide a system that enables a distributed information access device to be used for various purposes and can offer motivation for use for an original purpose intended by the distributor. SOLUTION: The information access device 1101 or an input device 1102 has a purpose determining means and a use limiting means, and the use limiting means is operationally controlled according to determination results of the purpose determining means. For example, the distributed camera 1102 reads in a link symbol on a printed matter 104, and the PC 1101 uses a network to access an information server 1301 as an information destination of the link symbol via a relay server 1201 operated by an information delivery service entity 102. Use for such an original purpose prolongs the period before the use limiting means are activated. When the camera 1102 is used, on the other hand, for image capture or the like other than the original purpose, the period before the use limiting means are activated is shortened.

摘要： PURPOSE:To improve the reliability of a cooling function of hardware by switching a stopped cooling fan in a computer system to another cooling fan. CONSTITUTION:A fan control part 3 selects a fan indicating either one of fans 4a, 4b from fans stored in a fan switching register 32 to acturate the selected fan. When a sensor for detecting the stop of a driven fan detects abnormality, data indicating the fan generating the abnormality are written in a fan stop detecting register 31 and a CPU 1 writes data indicating the other fan in the register 32. Thereby the fan control part 3 switches the output of a power supply relay 6 to switch the fan generating the abnormality to the normal fan. Since a failed fan can be switched to the other fan, the computer system can be continuously operated and its reliability can be improved.
