Title: Isolated analog voltage sense circuit
IPC: H02M3/335
Filed: 1988-08-04
Abstract: An improved isolated analog voltage sensing circuit which has isolated windings (102A, 102B) of a transformer (102). Sensor means (106, 256) sense the input voltage and apply this to the input winding (102A) of the transformer. A capacitor (116) is connected to the output winding (102B) of the transformer via switching means (110), so coupling the capacitor to the input voltage. An oscillating clock signal (122) controls switching means (110) to repeatedly connect and disconnect the capacitor to the output winding, whereby the capacitor will charge or discharge during the period that the switching means are conductive so that the voltage of the charge on the capacitor progressively moves at each cycle of the clock means towards a figure matching the input voltage sensed by the sensing means, the output voltage of the capacitor therefore providing a voltage which follows the input voltage but is isolated therefrom.

Title: Light emitting diode print head assembly
IPC: H01L33/48
Filed: 1989-08-02
Abstract: This technique for assembling a print head for an 
LED printer has LED dice (16) first assembled into precisely 
known locations on mounting tiles (13). A portion (19) of the 
front face of each tile (13) is left exposed beyond anything 
mounted on the tile (13). The tiles (13) are then assembled with 
these exposed areas (19) on a planar reference (32) on an assembly 
fixture (31). Reference surfaces (34,36) built into the fixture (31) 
align the edges of the tiles (13), and hence the LED dice (16). 
Finally a mother plate (10) is adhesively bonded onto the 
backs of the tiles (13). The adhesive accommodates thickness 
variations in the mounting tiles (13), and lack of flatness 
in the back surfaces of the tiles (13) and the front face of 
the mother plate (10). Reference tiles (41) coplanar with the 
reference plane formed by the front faces of the 
mounting tiles (13) provide a z axis reference.

Title: Optical directional coupler switch
IPC: G02F1/313
Filed: 1990-02-27
Abstract: An optical directional coupler switch is 
fabricated from a semiconductor substrate having a 
(111) plane. Thus, refractive indexes are changed for 
TE and TM modes by electrooptic effect, although the 
change amount is different between TE and TM modes. 
Therefore, a switching operation is realized for an 
incident light having any polarization. A device length 
L is preferrably set to meet an equation of "L TE  ≦ L ≦ 
L TM " (L TE  and L TM  are coupling lengths for TE and TM 
modes) to decrease a cross-talk, even if the coupling 
lengths are different between TE and TM modes, 
considering that the difference is small.

Title: Trigger switch
IPC: H01H9/06
Filed: 1990-04-09
Abstract: A trigger switch for hand-held electric power 
tools in which an actuating arm for actuating a switch 
mechanism is pivotally supported in a case by way of a 
pivot shaft (12) pivotally supported by a pair of parallel 
lateral walls defining the case (11), and a trigger member (32) 
having a front end and a pair of lateral flanges is 
pivotally supported by the case in a coaxial 
relationship with the pivot shaft by way of the lateral 
flanges. By securely coupling an extension of the 
pivot shaft with one of the flanges, the switch 
mechanism internally accommodated in the case can be 
actuated by operating the trigger member. Since the 
switch mechanism is internally accommodated in the 
case, a considerable saving of space can be 
accomplished. Since the coupling between the pivot 
shaft and the trigger member can be accomplished by the 
extension of the pivot shaft passed through the case by 
way of a round opening provided in the case, sealing of 
the switch mechanism can be easily accomplished.
