Patent CA-2184805-C (CA)
Inventor: GUAY BERNARD
IPC: H01P1/18
Filed: 1996-09-04
Granted: 2001-02-06
Abstract: A CML/ECL clock phase shifter device provides a 360° phase control range and, upon being provided with two CML clock signals related by a known phase difference, the device produces any desired phase in response to a control signal. The device uses a CMOS current switch which generates current signals having the amplitude adjustable with the control signal, which is a digital word. Differential pairs provide amplitude modulated current signals for the input clock and the variant of the input clock. Two MOS transmission networks selectively invert each amplitude modulated signal and sum the signals from each side on a load network. The phase control resolution is optimal over four quadrants for quadrature input clock signals.

A preferred apparatus includes one or more process heads (310) that has mounted thereto a rigid knife blade (311) for engagement with the moving web (302). The knife blade (311) is movable vertically and rotationally. The process heads (310) are also movable horizontally along the path of the moving web (302). A plurality of macro and micro tension zones (5, 6, 7, 8, 9, 10 and 11) are established and are monitored for controlling the apparatus and process. Additional measurements of web density, micro porosity, placement of an internal layer of polymer within the web, analysis of elements on the treated web, and the size of the polymer bead applied to the moving web are measured for controlling online the apparatus and the process of this invention. This method and apparatus produces webs that either has some of its structural elements encapsulated by the polymer composition while at least some of the interstitial spaces of the web are open; or has an internal layer extending through the web in a direction generally spaced from at least one major surface thereof; or has both encapsulated structural elements and an internal layer of polymer composition.

Granted: 2001-05-22
Abstract: An electronic delay detonator comprises an electronic timer (100) and an electric detonator (200) fired by ignition of an ignition element. The timer includes an energy charging circuit (120) for storing electrical energy supplied from a power supply, a delay circuit (30) for counting a time period by using the electrical energy stored in the energy charging circuit to thereby output a trigger signal, and a switching circuit (140) for supplying the electrical energy stored in the energy charging circuit to the ignition element in response to the trigger signal. To an impact externally applied to the electronic delay detonator, a lower limit of an impact value in an induced detonation range of the electric detonator substantially overlaps with an upper limit of an impact value in a range in which the electronic timer is operable. Thus, no explosive remains misfired even in adverse use environments. When the damage of the quartz oscillator (131) is detected, the electric detonation is fired in response to the detected signal.
