Abstract: A pair of opposite end portions of a buckling exothermic body as an exothermic resistor are fixed onto a substrate via insulating members. The buckling exothermic body heats with resistance thereof by applying a voltage from a power source to the buckling exothermic body via a switch. As inner temperature of the exothermic resistor reaches a predetermined temperature or higher required for the exothermic resistor to buckle, and a compressive force exceeds a buckling load, the exothermic resistor buckles and distorts towards thermosensible paper from a non-shifted state in which there is virtually no thermal stress. As the buckled and distorted exothermic resistor comes into contact with the thermosensible paper, recording, such as printing, is performed only at the contact portion. This reduces thermal mutual interference between neighboring buckling exothermic bodies. As a result, recording of high resolution and high print quality is performed. Moreover, since, unlike the prior art, there is no need to provide an abrasion protection layer, production costs can be cut down and a smaller and lighter head can be made.

Abstract: An ink jet head, having a long life, capable of discharging ink with a strong force and at a high speed is provided at a small size. A container comprises a casing and a nozzle plate covering the upper surface of the casing and an ink discharge opening. A buckling structure is fixed at its longitudinal ends to the bottom surface of the container via an installing member, and its center portion can be deformed upward by buckling. A diaphragm is positioned above the buckling structure with a space therebetween and placed on an inner wall of the casing with its periphery fixed thereto so as to liquid-tightly partition the inside of the container into a space and an ink chamber. A connection member connects the diaphragm and the buckling structure at their center. Electrodes are provided at both ends of the buckling structure to generate thermal stress therein by supplying electric current for buckling and consequently to apply pressure to ink in the ink chamber for discharging.

Abstract: A solidification analysis method of a cast that can predict a molten temperature drop history with fine precision is disclosed. The analysis is performed by considering different latent heat emitting patterns according to the differences of the cooling speeds. An analysis model having a plurality of elements is used. A cooling speed is calculated in each element by performing a calculation of heat transfer between the elements adjacent to each other. A temperature fluctuation range is revised in each element when a temperature fluctuates from emission of solidification latent heat based on the calculated cooling speed and a predetermined fraction solid-temperature curve of a molten alloy. A solidification analysis of the analysis model is performed by using the revised temperature fluctuation range.
