A thermal head has heating elements that can be selectively driven independently from one another during a driving operation to directly heat, and thereby thermally activate, regions of a heat-sensitive adhesive layer of a heat-sensitive adhesive sheet while the heat-sensitive adhesive sheet is moved relative to the thermal head with the heating elements disposed in opposing relation to the respective regions of the heat-sensitive adhesive layer. All but at least one of the heating elements are selectively driven so that (a) a preselected region of the heat-sensitive adhesive layer disposed in opposing relation to each non-driven heating element is not directly heated, and thereby not directly thermally activated, by the non-driven heating element, (b) the regions of the heat-sensitive adhesive layer disposed in opposing relation to the respective driven heating elements are directly heated, and thereby directly thermally activated, by the respective driven heating elements, and (c) each preselected region of the heat-sensitive adhesive layer opposed to a non-driven heating element is thermally activated with heat transmitted from surrounding directly heated regions of the heat-sensitive adhesive layer of the heat-sensitive adhesive sheet.
摘要:
In a thermal activation method for a heat-sensitive adhesive sheet 2 which has a heat-sensitive adhesive layer 2a on one surface thereof and is to be stuck to an adherend 1, when a surface roughness of the adherend 1 is large, by heating the heat-sensitive adhesive layer 2a with large thermal energy, an adhesive is allowed to easily enter recesses 1a of the adherend. When the surface roughness of the adherend 1 is small, by heating the heat-sensitive adhesive layer 2a with small thermal energy, a viscosity of the adhesive is increased to thereby prevent the heat-sensitive adhesive sheet 2 from sliding and being peeled. The surface roughnesses of the adherends 1 may be classified for each material of the adherends 1, and the classified surface roughnesses may be judged according to each material of the adherends 1 to thereby determine the thermal energy.

摘要:
A thermal activation device has a thermal head having heat generating elements for thermally activating a heat-sensitive adhesive layer of a heat-sensitive self-adhesive sheet. The heat-sensitive self-adhesive sheet has a sheet-like substrate having a printable surface on a first side thereof and the heat-sensitive adhesive layer on a second side thereof. An energy control device controls the thermal head by applying one or more voltage pulses to the heat generating elements for energizing the heat generating elements to thereby thermally activate an area of the heat-sensitive self-adhesive layer in one step. When a series of the voltage pulses are applied to the heat generating elements, the energy control device selectively switches between the heat generating elements to be energized by the voltage pulses each time one of the voltage pulses is applied.

An image display apparatus has a display part composed of plural pixels; a control part for controlling the display part; and a signal line arranged inside the display part for inputting a display signal into the pixel. The pixel has at least one or more switches and first capacitances for storing the display signal input through the signal line as a charge for a designated period of time or longer. The pixel also operates to rewrite the display signal stored in the first capacitance into the first capacitance without using the signal line in response to an instruction of the control part.
