Title: Driving signal for coarse servo employing sampled offset signal
Inventor: GETREUER KURT WALTER
IPC: G11B7/085
Filed: 1987-08-18
Abstract: Disclosed is an information storage assembly having fine and coarse actuators each having associated servo loops wherein movement of the fine actuator causes a shift in the location of the returned beam spot on at least one split detector (with reference to said split). 
     The assembly comprises media containing informa­tion tracks having at least two servo sigments for genera­ting servo signals therefrom. The first segment S₁ com­prising modulations of the information track sufficient to indicate in a returned beam the deviation from track center line of the incident on the disk beam when said return beam impinges on a split detector means. The second segment S₂ comprises an area of said track having no de­tectable modulation so as to provide a returned beam for use in indicating the misalignment of the optical pathway. 
     The coarse actuator servo signal is generated from said media by an apparatus comprising said split de­tector means for receiving said signals from either half of said split detector means and indicating the difference there between in an output signal, sample and hold gate means for allowing to pass only that portion of the signal output by said differentiating means which is representa­tive of the return beam returned simultaneously with the passage of mirrored areas on the disk. This signal from said sample and hold gate means is fed directly into the servo loop.

Abstract: A method for flattening round wire and winding a main field coil with the round wire in­cludes the steps of feeding a length of round wire through a pair of non-driven pinch rollers to impart a predetermined degree of flattening such that as the wire is wrapped around the rotating main field, it can be laid into the trough in precision manner with successive turns vertically aligned. The flattened round wire is laid into the trough with the flat of the wire parallel to the bottom of the trough to in­crease the stability of the winding, and to facili­tate the vertical alignment of successive layers.

Inventor: AGRAWAL OM P
IPC: G06F9/22
Filed: 1987-06-25
Abstract: A programmable controller which combines microaddress control logic, memory, a microinstruction decoder, and I/O into a unitary, integrated device. The microaddress control logic is responsive to sequencing signals developed by the microinstruction decoder, and includes an address generator which develops the program address. The memory, which can be either PROM or RAM, is addressed by the address and outputs a microinstruction word to a pipeline register. The microinstruction word has an internal field which is coupled to inputs of the microaddress control logic and the microinstruction decoder, and a control field which is coupled to an output buffer. The output buffer includes multiplexers which permit either the program count or the control field to be multiplexed to the output pins of the device. When the program address is multiplexed to the output pins, the programmable controller can address external memory devices.

IPC: A43D119/00
Filed: 1987-11-03
Abstract: A system for identifying workpiece by scanning them and "reading" details of their configuration (shape) is adapted for treating them in accordance with a desired pattern, e.g. applying a desired pattern of material in liquid form (e.g. ink) or in powder form (e.g. toner material or a hot melt adhesive) to the workpieces, regardless of their location and orientation on a workpiece support (18, 118). This is achieved by modifying pattern data (relating to the desired pattern) selected from a store (memory) in accordance with positional data (relating to the workpiece location and orientation) obtained during scanning (Figure 2). Where the applied material is liquid, a suitable tool is a pen (152) or other liquid applicator; where in powder form, a suitable tool is an electrostatic printer (36), e.g. an ionographic printer.

Abstract: A degassing apparatus (12) for a metal mold (11) comprises a valve body and a bypass. The valve body (24) is slidably provided between an end of a vent groove communicating with a metal mold cavity (14) and a valve opening/closing portion before an exhaust hole. When a molten metal flowing from the cavity acts on a surface of the valve body, the valve body moves toward the exhaust hole and blocks a path toward the exhaust hole. The bypass (26) bypasses a valve head (24b) of the valve body from the vent groove and guides gas to the exhaust hole. The valve head of the valve body has a substantially head-cutting conical outer shape projecting in the direction of the vent groove (15). The vent groove has a gas vent path (25) extending from a top portion to the vicinity of the base of the valve head along an outer surface of the valve head. An end portion of the gas vent path corresponding to the base of the valve head communicates with a start portion of the bypass which bypasses the valve head.

IPC: H04N5/932
Filed: 1982-10-27
Abstract: A method and apparatus for generating an artificial vertical sync pulse for controlling the scanning drum servo of helical wrap magnetic video tape recording and reproducing machine is disclosed. The artificial vertical sync pulse is less susceptible of experiencing timing errors relative to control track signals caused by tape expansion or contraction because it is physically much closer to the control track head than the conventional vertical sync signal that is normally used to control the scanning drum servo. A component of the beginning portion of the vertical synchronizing signals that is physically present on one side of the drop-out area is detected and this component triggers a counter which opens a window for detecting a particular horizontal sync pulse that is physically close to the control track head and the horizontal sync pulse defines the artificial vertical sync pulse.

IPC: H03K17/78
Filed: 1988-08-12
Abstract: A generator of short electromagnetic pulses utilizes a photoconductive switch (19) having metallic strips on a substrate with a gap separation therebetween. A timing circuit (11) provides an electrical signal to the input of the photoconductive switch (19) and a trigger to an optical source (15) causing a short burst of optical energy to illuminate the gap between the metallic strips, thereby causing the photoconductive substrate to provide a low impedance path between the metallic strips and coupling the electrical signal to an output terminal of the photoconductive switch (19) for the duration of the optical pulse. A filter (21) coupled to the output terminal of the switch (19), via an impedance matching section, selects a signal frequency band for further transmission.

Abstract: A variable speed transmission assembly comprising a variator (3) connected between main power input and output shafts (1 and 4). A power split differential gear assembly (2) splits power from the input between the output and the variator. The variator output is connected to a ratio spread differential (5), one output of which is connected to the main power output shaft, the other output also feeding the variator input. The main advantage is that the variator handles less than one half of the total power. Secondly, the variator input runs at a speed which is inversely proportional to the output speed. In this way, the variator is better able to handle its power through put.
