摘要:
The present invention is a replaceable ink container for use with a printing apparatus. The printing apparatus of the type having out of ink detection. The replaceable ink container includes a fluid reservoir having an outlet. The outlet is configured for connection to a fluid inlet associated with the printing apparatus. Also included in the replaceable ink container is an actuator engagement device for engaging an actuator associated with the printing apparatus. The actuator is of the type that is movable between a first position wherein an out of ink signal is generated and a second position. The actuator engagement device is disposed and arranged to engage the actuator to prevent movement of the actuator from the second position to the first position thereby preventing the out of ink signal.

A means is provided to eliminate ink trajectory errors when an inkjet printhead is fabricated as described below. In a preferred embodiment, a nozzle member containing an array of orifices is affixed to a barrier layer formed on a substrate, the substrate having heater elements formed thereon. The nozzle member is affixed to the barrier layer using heat and pressure. Each orifice in the nozzle member is associated with a single heating element formed on the substrate. The back surface of the nozzle member extends beyond the outer edges of the substrate. During the heating and pressure step used to affix the nozzle member to the barrier layer, the nozzle member undesirable bends over the outer edges of the barrier layer, causing the nozzles to be tilted outward. Disclosed is a method and design wherein the barrier layer is formed with one or more trenches parallel to the long edges of the barrier layer and with backward peninsulas formed in the barrier layer and extending into the trenches to cause the nozzle member to dip and bend over the trenches and backward peninsulas in an mount approximately equal to the bend into the ink channels on the outer edge of the substrate. The nozzles are located at the crest of the bent nozzle member and thus remain normal to the surface of the printhead.

A modified syringe for recharging an ink supply in a print cartridge is described. In the preferred embodiment, the end of a syringe valve is inserted into the end of a print cartridge valve to create both a mechanical coupling and a fluid tight coupling between the two valves. A further insertion causes both valves to become open, thus creating an airtight fluid path between the syringe chamber and the depleted print cartridge reservoir. A negative pressure within the print cartridge ink bag draws the ink from the syringe chamber into the ink bag until the ink bag is substantially full and the pressure in the ink bag is at or near atmospheric pressure. An air intake port is provided on the syringe to fill the void left by the ink in the syringe chamber. Once the print cartridge has been recharged, a plunger in the syringe is manually pulled back a predetermined distance to draw an amount of ink out of the print cartridge to create the desired negative pressure in the print cartridge. The syringe is then removed from the print cartridge, automatically pulling the two valves closed.

Described is an inkjet print cartridge including an ink reservoir; a substrate having a plurality of individual ink firing chambers with an ink firing element in each chamber; said ink firing chambers arranged in a first chamber array and a second chamber array and said firing chambers spaced so as to provide 600 dots per inch printing; an ink channel connecting said reservoir with said ink firing chambers, said channel including a primary channel connected at a first end with said reservoir and at a second end to a secondary channel; a separate inlet passage for each firing chamber connecting said secondary channel with said firing chamber for allowing high frequency refill of the firing chamber; a group of said firing chambers in adjacent relationship forming a primitive in which only one firing chamber in said primitive is activated at a time; a first circuit on said substrate connected to said firing elements; and a second circuit on said cartridge connected to said first circuit, for transmitting firing signals to said ink firing elements at a predetermined frequency. The preferred configuration of the nozzle member, ink channels, and firing chambers allows a printing resolution of 600 dots per inch.

A substrate for the print head of an ink jet printer includes a plastic base, a metallization layer overlying the plastic base, and a dielectric structure overlying the metallization layer. A thin film resistor is deposited over the substrate, as required. Preferred materials include polyimide plastic for the base, chromium for the metallization layer, and a bilayer construction of silicon dioxide overlying titanium for the dielectric structure.

A shaving implement includes a blade assembly configured for a wet shaving process wherein a user of the shaving implement grips a handle and draws the blade assembly across a surface of skin to be shaved. The shaving implement also includes an energy-imparting device, circuitry, and an activation device. The energy-imparting device is configured to impart energy to enhance the wet shaving process. The activation device is configured to impart a signal to the circuitry in response to handling of the shaving implement during the wet shaving process. In response to receiving the signal, the circuitry either extends or initiates an application of signals to the energy-imparting device that enable the energy-imparting device to impart energy that enhances the wet shaving process.

A method of making a pharmaceutically active ingredient abuse-prevention device includes providing a pharmaceutically active ingredient and providing an antagonist of the pharmaceutically active ingredient. The antagonist is in selective fluid communication with the pharmaceutically active ingredient. Electronic circuitry is configured to selectively operate the fluid communication between the antagonist and the pharmaceutically active ingredient so as to mix the pharmaceutically active ingredient with the antagonist upon recognition of one or more predetermined fault conditions. Mixing the pharmaceutically active ingredient with the antagonist renders the pharmaceutically active ingredient substantially ineffective.
