Filed: 1990-02-05
Abstract: A process for fabricating field effect transistors with lightly doped drain (LDD) regions having a selected width includes a method of optically detecting the width of spacers used to mask the LDD regions during the source and drain implant and a method of electrically determining (confirming) the width of the LDD regions.

Title: Rf tracking servo for vtr
IPC: G11B15/467
Filed: 1990-03-23
Abstract: A video signal is recorded in oblique tracks on 
a magnetic tape. The tracks are successively scanned by 
rotary heads, and a reproduced radio frequency signal is 
obtained. The level of the signal as reproduced exhibits 
a nonlinearity as a function of deviations of the rotary 
heads from the successively scanned oblique tracks. In 
accordance with the invention, the running speed of the 
tape is controlled on the basis of the detected changes 
in signal level, and the gain of the reproduced radio 
frequency signal is controlled in such a way as to 
compensate for the nonlinearity of the reproduced signal.

Title: Methods and apparatus for making multiple component smoking articles
IPC: A24D1/22
Filed: 1990-04-12
Abstract: Relatively fragile components (20) for cigarette-like smoking 
articles are wrapped with an overwrap (42) by bringing an exposed 
axial surface portion of the component into resilient contact (N) 
with the overwrap, and by then rolling the component about its 
longitudinal axis (186,188) again by resiliently contacting the 
component. Smoking articles including the foregoing components as 
the distal component and at least one proximal component are made 
by, first, supplying a pair of distal components with their distal 
ends facing one another and pushed up against an interposed stop. 
The overwrap is slit parallel to the stop just prior to application 
to the distal components. After overwrapping, the distal 
components are reoriented so that their distal ends face away from 
one another. A pair of proximal components is then placed between 
the distal components, and each proximal component is joined to the 
adjacent distal component by a tipping overwrap.

Title: Feeding device
IPC: B65H1/26
Filed: 1990-05-09
Abstract: A feeding device in accordance with the present 
invention comprises a lateral feed position sensor (HP1) for 
detecting that a rotatable cassette is placed in a lateral 
feed position, a longitudinal feed position sensor (HP2) for 
detecting that a rotatable cassette (32) is placed in a 
longitudinal feed position and a control device for 
controlling a cassette rotating motor based on the input 
coming from the lateral feed position sensor or the 
longitudinal feed position sensor, such that the 
longitudinal or lateral feed position of the rotatable 
cassette and the longitudinal or lateral feed position of 
a fixed cassette differ, whereby a situation where the 
rotatable cassette and the fixed cassette that contain 
copy paper sheets of the same size, are placed in the same 
longitudinal or lateral feed position, can be avoided and 
the time needed for feeding the required amount of copy 
paper sheets in the apparatus the feeding device is 
attached to, may be shortened.  
     A feeding device in accordance with the present 
invention comprises in addition to the above arrangement, 
a rotation prohibition input device (52) for inputting to the 
control device an instruction prohibiting the rotation of 
the rotatable cassette, and is arranged such that the 
control device cancels the control to the cassette 
rotating motor in response to the input coming from the 
rotation prohibition input device. As a result, the time 
needed for feeding the required amount of copy paper 
sheets in the apparatus the feeding device is attached to 
may be shortened, and in addition for example when the 
rotatable cassette and the fixed cassette contain copy 
paper sheets of the same size and are placed in the same 
longitudinal or lateral feed position, a large amount of 
copy paper sheets can be supplied continuously when 
necessary.
