[Also in Divisions C1 and H1] In order to separate a substrate 16 into two portions a laser beam 12 of sufficient power to produce a localized thermal shock to generate a localized fracture through the entire thickness of the substrate 16 is directed on to the surface of the substrate and relative movement between the substrate and beam is produced so that the fracture is propagated along the boundary between the two portions. The substrate 16 such as glass, ceramic, quartz, sapphire or a slice of semi-conductor such as germanium or silicon upon which electrical circuits or components may be mounted is positioned on movable carriage 18. A laser beam 12 from C.W. molecular gas laser 11 is focused on to a point 13 on the substrate and is of such power that due to the resulting local temperature gradient at point 13 producing expansion of the substrate a localized fracture is formed, Fig. 3 (not shown), extending through the substrate. As the substrate 16 is moved on carriage 18, the fracture follows the line of the beam on the substrate. The substrate may be supported on a pair of knife edges to reduce the energy transferred to the carriage. Fig. 2 (not shown). Examples are given of various beam power levels for different substrate materials, thicknesses and displacement rates.

Patent GB-2005053-A (GB)
Title: Electronic timepieces
IPC: G04C3/14
Filed: 1978-08-02
Abstract: In an electronic watch a non-operation detecting circuit detects the non-operative condition of the stepping motor of the watch and produces a non-operation signal each time the stepping motor fails to operate in response to the standard pulse which drives the same. A counter counts the number of non-operation signals and stores the count for later use. A rotation detecting circuit detects the resumption of operation of the stepping motor in response to the standard pulse from the non-operative condition and a quick feed control circuit quickly advances the stepping motor in response to an input from the rotation detection circuit by thereafter supplying, instead of the standard pulses, the quick feed pulses to the drive circuit for the motor equal in number to the number of the non-operation signals counted in the counter. In this way the corrected time will be displayed by the watch even after being rendered inoperative as a result of an external condition such as low temperature or a high strength DC magnetic field.

Title: Sheet-detector device for use in sheet-processing apparatus
IPC: G03G15/00
Filed: 1978-09-04
Abstract: Sheets, especially paper sheets, entering the nip between a pair of rollers are detected through causing interruption of the electrical connection between a sensor contact at or near the nip and a conductive surface on one of the rollers. The contact is resiliently biassed against that surface. Operations in a sheet-processing apparatus (for example, an electrostatic copying apparatus) are controlled in response to the detection of sheets. The sensor contact may comprise one or more resiliently flexible members, may be located in a recess in the roller not having the conductive surface, and may be mounted on a removable support for purposes of exchange and/or repair. The described device reduces the possibility of damage to sheets during transport, and of interference in sheet transport, while allowing sufficient contact pressure to allow the use of currents high enough for reliable control purposes. <IMAGE>
