Abstract:
A manufacturing method of monolithic integrated thermal bubble inkjet print heads and the structure for the same. The method utilizes semiconductor manufacturing technologies to configure various elements in a thermal bubble inkjet print head, such as ink channels, an ink slot, an energy transducer, an orifice plate, on a single substrate. The ink channels are formed on an top surface of the substrate using the anisotropic etching technique. The ink slot is formed on a back surface of the substrate using the anisotropic etching technique. The energy transducer and the orifice plate are formed in order above the ink channels using the coating and etching techniques. This thermal bubble inkjet print head manufacturing method is particularly useful in the all batch process without employing the steps of precision alignment joint for the orifice plate in a conventional inkjet print head. Therefore, the method can greatly increase production efficiency and lower production costs.
Abstract:
The locking and ejecting apparatus includes a latching mechanism, an ejection mechanism, a first string and a second string. The latching mechanism is for locking the module device in a locked position or unlocking the module device from the locked position. The ejection mechanism is for ejecting the module device on disengagement of the latching mechanism from the locked position. During the unlocking and ejecting operations, the second button is pulled right after the first button is pressed. After the module device is released from the locked position and ejected out of the internal bay, the first spring positioned to generate a first force restores the latching mechanism and the second spring positioned to generate a second force restores the ejection mechanism.
Abstract:
To install a hard disk drive in a portable computer base housing, an upwardly opening well area is formed within the base housing and is sized to closely receive the disk drive. An electrical connector projects horizontally inwardly through one end of the well area and is operatively mateable with a corresponding connector on the front end of the disk drive. A flexible lowering strap is secured to the rear end of the disk drive. To install the disk drive, its front end is lowered into the well area while holding the strap to keep the rear end of the disk drive elevated. The strap is then used to controllably lower the balance of the disk drive into the well area to prevent installation shock to the disk drive that might occur if it were simply dropped into the well area. The lowered disk drive is then slid along the bottom of the well area to mate the well area and disk drive connectors. A clamping bar member is then extended along a rear top end portion of the installed disk drive and used to hold the disk drive firmly against the bottom side of the well area, thereby rigidly coupling the installed disk drive to the balance of the base housing in a manner eliminating the necessity of a separate shock and vibration isolation apparatus for the disk drive.
Abstract:
An ink print head has an ink container for storing fluid, a chip installed at a bottom of the ink container having a central slot for passing fluid, and a dry film formed on the chip having a plurality of ink chambers. The ink print head also has a nozzle plate formed below the dry film, a middle portion of the nozzle plate protruding above the nozzle plate so as to form a central refill chamber, a plurality of nozzles corresponding to the ink chambers of the dry film, and a plurality of heaters set on the chip for heating fluid inside the ink chambers so that the fluid can be ejected from the nozzles of the nozzle plate. The fluid inside the ink container will flow through the central slot into the central refill chamber and then into the ink chambers.
