Filed: 1988-11-04
Abstract: The specification discloses output buffer 
circuitry (10) for providing selected output driving 
characteristics. A plurality of input terminals (13, 24 
and 30) receive control and data signals. A plurality of 
interconnected driver transistors (20, 28, 36 and 42) are 
connected to an output terminal (22). Drive selector 
circuitry (16, 18, 38 and 40) is connected between the

Title: Stationary head tape drive
IPC: G11B15/18
Filed: 1989-10-02
Abstract: The present invention is an end loaded tape drive for 
an elongate tape cartridge (20) having a door (26) in one of its 
sides proximate one end of the cartridge. The tape drive 
includes an elongate table (70) mounted at least partially

cartridge door opening mechanism (360) is provided for opening 
the access door of the cartridge sufficiently to provide 
access to the tape by the magnetic head. Movement of the 
table in the y direction actuates the door opening 
mechanism and movement of the table in the x direction

Title: Hair-plucking apparatus
IPC: A45D26/00
Filed: 1989-01-06
Abstract: Hair plucking apparatus comprising a rotating plucking roller formed by a series of blades disposed side by side. The blades (5a, 5b) of this roller are mounted in a movable manner on their drive shaft (6) in order to be able to pivot about an axis perpendicular to this shaft. It is furthermore provided with mechanical means for operating these blades, which are capable of causing, at least once per revolution of the roller (4), the pivoting of these blades (5a, 5b), one in one direction and the following one in the opposite direction, each about a separate axis (x.x') perpendicular to the drive shaft. In this way the tightening of two adjacent blades against each other is obtained at the working surface and consequently the gripping of hairs between these blades in order to pluck them.

Patent EP-0325514-A3 (EP)
IPC: H01L21/66
Filed: 1989-01-12
Abstract: Presence, absence, and adequacy of length of 
component leads (4) are detectable by engaging each 
lead (4) with a corresponding interposer (50) and 
monitoring the amount of displacement of each 
interposer or plunger (50) in response to the lead. 
Each plunger is provided with an optic fiber (56) for 
guiding and directing a light beam from a transmitter 
(22) to a receiver (20) of a sensor (18) when a lead is 
missing or too short. The lead engaging portion (60) of 
the plunger (50) is interchangeable to accommodate 
different lengths of leads and heights of cut and 
clinch anvils (30). For DIP components, each half of 
the inventive device receives all of the leads on one 
side of the component, with an individual piston (50) 
for each lead. Thus, mirror image devices may be used 
for oppositely spaced rows of leads of a DIP, with the 
spacing between the mirrored halves of the device being 
adjustable according to the center-to-center (CTC) 
spacing between leads on opposite sides of the 
component body. Each plunger of one of the mirror 
halves is simultaneously engaged by a fluid common to 
the remaining pistons thereof for extension, as well as 
retraction, of the lead engaging portions.

Title: Method and device for cleaning the cylinders of a rotary web printing machine
IPC: B41F33/00
Filed: 1990-01-11
Abstract: The invention relates to a method and a device for cleaning the blankets of a web-fed rotary offset printing machine when the web (1) is running. Since the washing means, used for dissolving the ink and paper residues on the blanket, passes via the printed web (1) into the dryer, an undesirably high evaporation of solvent can occur in the dryer. As a preventive measure, the loading of solvent on the web (1) is acted upon in that a scraping contact (9) is formed before the web enters the drying route and/or a pre-evaporation is applied by suction to lower the concentration. The measure extends over the period of the blanket cylinder (5) being washed until the last section of the web receiving transferred washing means has passed through. The suction device (14) is preferably connected to the exhaust air cleaning system, arranged downstream of the dryer.

Title: A device for determining position coordinates of points on a surface
IPC: G06F3/046
Filed: 1990-03-22
Abstract: A device for determining position coordinates 
of points on a surface, has a tablet containing plural 
number of equally spaced driver windings and plural 
number of equally spaced sense windings. Each driver 
winding has a pair of parallel conductors laid in X-­
direction, and each sense winding has a pair of parallel 
conductors laid in Y-direction. A current is generated 
in a cursor coil by the voltage induced from the current 
in a nearby situated driver winding. This current in the 
cursor coil induces a voltage in a nearby situated sense 
winding. The X-position of a sense winding in which a 
maximum voltage is induced, and the Y-position of a 
driver winding which induces a maximum voltage in the 
cursor coil, determine the position coordinates of the 
cursor on the tablet. Auxiliary sense windings are 
supplemented to the tablet. Induced voltages on these 
auxiliary sense windings determine the Y-position of the 
cursor in disregard to its X-position, and reduce the 
overall time required for position determination.
