Abstract: An electronic-device housing stores an electronic circuit and a cooling fan. The electronic-device housing includes a first surface having at least one opening to release heat outside. At least one projected portion projects toward an outside of the electronic-device housing, and when the electronic-device housing is installed on an installation surface so that the first surface is opposed to the installation surface and the projected portion comes into contact with the installation surface, a rotation moment acting on a gravity center of the electronic-device housing acts in a direction where the rotation moment causes the first surface to move away from the installation surface.

Abstract: Provided is an electronic-device housing capable of storing therein an electronic circuit and a cooling fan, the electronic-device housing including a first surface having at least one opening to release heat outside, and at least one projected portion projected toward an outside of the electronic-device housing, and when the electronic-device housing is installed on an installation surface so that the first surface is opposed to the installation surface, and the projected portion comes into contact with the installation surface, a rotation moment acting on a gravity center of the electronic-device housing acts in a direction where the rotation moment causes the first surface to move away from the installation surface.

Abstract: Disclosed is an information processing device such as a compact personal computer, word-processor, and the like containing a printer therein. The information processing device is provided, in a side surface of its outer casing, with an opening portion so as to permit projection of an end portion of an ink cartridge or carriage. Therefore, although the device is compact-sized, it is possible to enlarge the printable width of the device. This makes it possible to effect printing on a larger-sized sheet of paper.

Abstract: A resistive ribbon thermal transfer printing apparatus produces two kinds of electric pulses for selectively energizing recording electrodes of a printing head according to a data to be printed. A first electric pulse (normal pulse) is applied to a recording electrode which is to be energized and is disposed between two recording electrodes which are to be energized. A second electric pulse (specific pulse) is smaller in energy than the normal pulse and is applied to a recording electrode which is to be energized and is not disposed between two recording electrodes which are to be energized. This selective application of the two kinds of pulses allows the size of the printed dots to become uniform.

Abstract: A print head with elongate electrical conductors and a fixing member containing hexagonal boron nitride, the elongate electrical conductors being embedded in or laminated on the fixing member and exposed at the tips. Electric signals are applied between the conductors and a printing medium to print thereon images corresponding to the electric signals.
