摘要: The illustrated receiver 6, in flip-flops 16A-D, stores four sequential samples of a biphase-L signal A1 and shifts the samples into four shift registers 24A-D. The sampled signals are clocked through their respective shift registers 24A-D by selected phases of multiphase clock .phi..sub.1, .phi..sub.2, .phi..sub.3, .phi..sub.4. Thus, each set of four samples is stationary at some location in their respective shift registers for the same clock cycle. A decoder section 10 responds to a transition between adjacent signal levels at the output of the shift registers 24A-D and to a previously sampled signal level A44. The decoder section 10 generates a control signal A32-D32 indicating the detection of a mid-bit biphase-L signal transition. A second storage means responds to the control signal A32-D32 and stores a shift register 24A-D signal level A19, B20-D20 which occurred subsequent to the detected mid-cell transition. The control signal A 32-D32 also synchronizes a recovered clock signal A14 used to clock recovered data A50 to external circuitry.

摘要: A mechanism for tilting a display screen of a CRT housed in a cabinet includes a projection extending from the bottom surface of the cabinet for supporting one end of the cabinet and providing a pivot point for tilting the cabinet. A foot slidably mounted at the other end of the cabinet supports that end at a selectable height; the foot having a ratchet rack on one of its surfaces is normally engaged by a detent lever locking the foot in position.

摘要: Apparatus for mounting a print head on a movable carriage which moves the print head across a record medium supported by a platen. The apparatus includes a projection extending from the front portion of the carriage, an opening in the print head arranged to accommodate the projection aligning the print head with respect to the platen, a compression spring maintaining the projection in the opening and a movable camming surface in contact with the projection for positioning the print head a variable distance away from the platen.

摘要: A method of manufacturing a thermal print head includes the step of coating a channel 12 of a fixture 10 with a first adhesive 26. Integrated circuit packages 20 are placed in the channel 12 with heating elements 22 disposed toward the bottom 14 of the channel 12. The packages 20 are held in position by a jig 30 while the adhesive 26 is thermally activated. A groove 52 in the face of a heat sink 50 is filled with a first part 54 of a two part adhesive and the integrated circuit packages 20 coated with the second part 56 of the two part adhesive. The alignment fixture 10 is positioned over the heat sink 50 activating the two part adhesive. The temperature of the assembly is elevated causing the first adhesive 26 to release and the second adhesive 54, 56 to further cure thus securing the packages 20 to the heat sink 50. Printed circuit cables 60, 70 are soldered to the packages 20.

摘要: The illustrated ink jet (19) includes a chamber (22) containing a quantity of ink (54) discharged through a nozzle orifice (28) in the form of droplets (84). The ink is discharged in response to movement of an actuator positioned over a chamber (22) opening. The actuator (50) includes a piezoceramic plate (60), the surfaces of which are covered by electrodes (62, 64). Soldered to the electrode (62) is a bending plate (56) which is secured by adhesive (58) to a flexible sheet of insulating material (52). Control signals are fed through conductors (72, 59) to the electrodes (62, 64).
