Title: Plotter pen ink level detector
IPC: B43K5/12
Filed: 1989-08-08
Abstract: In a computer controlled automatic plotting device, an 
ink level detector is provided in a plotter pen cartridge (23). An 
ink-following object (27) is provided in the plotter pen cartridge and 
is supported by the writing fluid (26). The ink-following object 
carried a magnet (36). As the ink-following object traverses down the 
inside of the plotter pen cartridge, the position of the magnet 
triggers a sensor at a predetermined level. The sensor (46) then 
effects a visual or audible signal to alert an operator that the 
cartridge is running out of writing fluid. Alternatively, the 
sensor activates a control system to shut down the plotting de­
vice to permit replacement of the plotter pen cartridge with one 
having a new ink supply.

Title: Surgical pressure plaster
IPC: A61F13/38
Filed: 1989-02-16
Abstract: A surgical pressure plaster has a pressure pad 8 
of readily compressible, resilient material, preferably 
having a trapezoidal cross-section with its non-parallel 
sides equal. The pressure pad is attached lengthwise and 
centrally to the adhesive surface of a highly elastic 
adhesive tape 7. Two removable protective strips 5 and 6 
overlie the tacky surface of the elastic tape in end 
regions thereof and are of material stiff enough for them 
to have been inherently curved or angled into sections 
(5a, 6c) at right angles to sections adhering to the 
elastic tape. The protective strip may extend over the 
top surface (13) of the pad which needs to be kept sterile 
through further anglings thereof. Using one hand only, 
digital pressure is exerted on the pressure pad's sides 
causing rotation of the projecting strips away from the 
pad whose surface (13) is pressed onto a venepuncture wound 
site. The strips are removed, the tape ends, each 
stretched, are then applied to the skin, and the pad now 
maintains pressure on the wound and prevents bleeding.

Filed: 1990-05-16
Abstract: A sense amplifier circuit for use in a ROM comprises an 
excess charge detecting circuit (24) for producing a detection 
output when a potential of a bit line (BL) exceeds a normal

bit line potential to the normal value.  
     The excess charge detecting circuit and the excess charge 
discharge circuit can be realized by a diode-connected 
transistor (24d,25c) connected between the bit line (BL) and an 
inverter (23) of the sense amplifier. When the bit line 
potential is about to exceed the predetermined value, the
