Abstract: A nozzle cover assembly for an ink-on-demand type ink jet printer is provided. The assembly includes a nozzle cover having a recess on one side in order to form a chamber between the cover and the nozzle. A pressure maintaining device communicates with the recess for maintaining constant pressure in the chamber, thereby preventing ink from being pushed back to an ink supply tank side or from leaking out of the nozzle.

Abstract: In an electrothermal transfer system which uses a sheet formed by integrally binding at least a resistive layer and an ink layer and effects desired transfer by flowing electric current through the resistive layer thereby causing the resistive layer to generate joulean heat and enabling the ink layer to be partially fused to be transferred, an electrothermal transfer recording sheet has the resistive layer formed by application of a mixture of carbon black with a resin binder. The carbon black used herein is possessed of a DBP oil absorption capacity of not less than 300 ml/100 g. Thus, the carbon black content in the resistive layer can be as small as 5 to 35% by weight, the tight adhesiveness of the resistive layer improved, and the power consumption lowered.

A paper feed drive for feeding paper one time per revolution of the type drum includes an intermittent tooth on an end of the support member, a feed gear for being turned by engagement with the intermittent gear, and a paper feed roller driven by the feed gear to feed paper to be printed on. A generating means including a cam on the type drum, positively generates an output indicative of a given position of the type drum.

Abstract: A serial print element for use with a serial matrix font type printer for printing dot matrix type graphics with a serial matrix font type printer and a method of printing dot matrix graphics with a serial matrix font type printer. The print element includes a carrier for supporting type elements. The print element is coupled to the carrier and is capable of printing at least graphics images formed of dot patterns.

Abstract: This invention describes an improved resin mounting structure for use with an integrated circuit. An integrated circuit chip is affixed to a circuit substrate which has a hole. Circuit patterns connect to the contact pads of the integrated circuit chip and are added along the circuit substrate. An epoxy resin material is gated through the hole to surround and enclose the integrated circuit chip. In this invention, circuit patterns which are added beneath the integrated circuit chip are positioned over the hole in the substrate to allow an unimpeded flow of resin material. In addition, conductive spacing pegs are provided at each integrated circuit contact pad to allow for a uniform spacing between the integrated circuit and the circuit substrate and to provide for a more electrically and mechanically secure connection between the IC chip and the circuit substrate. Also, the circuit substrate is formed from a flexible material to absorb the displacement caused by differential thermal expansion.
