Abstract: A frequency multiplier design that uses a flip-flop to output (1) a first edge on an output clock signal upon receipt of a first transition of an input clock signal and (2) a second edge on the output clock signal before receipt of a second transition of the input clock signal is provided. The frequency multiplier design uses circuitry dependent on the output clock signal to reset the flip-flop after some delay but before the second transition of the input clock signal, wherein the resetting of the flip-flop causes the flip-flop to output the second edge on the output clock signal.

Abstract: A chucking apparatus 1 includes a chuck disk 11 and a chuck arm 17. The disk 11 is a disk lockable with a turn table 3. The arm 17 has an opening 33 through which the chuck disk 11 is insertable, and a holding part 31 where the disk 11 is rotatably arranged, plural first hooks 35 projecting inwardly radially from an edge of the opening 33, and a second hook 37 provided at the edge of the opening 33 for preventing the disk 11 in the part 31 from escaping outward.

Abstract: The present invention is a printer controller furnished with a processor for exclusively executing a first task (printing task) for controlling a print engine, a second task (communication task) for controlling communication with host computers, and a third task (language task) for generating image data. These tasks are assigned priorities of execution in the order of the printing task, the communication task, and the language task. When there is a request for the execution of a task with a higher priority during the execution of a task with a lower priority, the processor executes the higher priority task whose execution has been requested instead of the lower priority task currently being executed. Therefore, the processor is able to execute the communication task, language task, and printing task with no conflict.

Abstract: In a method for determining the flow rate of a fluid flowing in a channel (2), the fluid being constituted by a liquid or a gas, two pulse shaped, oscillating signals are sent through the medium with one signal directed against (14) and the other signal directed with (12) the flow direction (4) of the fluid. The transmitted signals are received and the flow rate is determined by means of the phase shift between the received, pulse shaped signals caused by the flow of the fluid. The phase shift (20) between the signals is determined while compensating for the dwell time of the pulse shaped oscillating signals in the fluid.

Abstract: An interface in an integrated circuit allows an LSSD storage element and a non-LSSD storage element to function together in the same scan chain. The interface has a data lock-up module, a test enable module, a master observe module, and a clock generator module. The data lock-up module latches data to be scanned into the integrated circuit through the scan chain. The test enable module indicates the status of a tester for testing the integrated circuit. The clock generator module generates a write clock and separate, non-overlapping master and slave scan clocks for a master latch and a slave latch in the LSSD storage element. The master observe module selectively asserts the slave scan clock prior to the master scan clock in order to latch the initial data bit appearing at the master latch.
