Title: Self-referencing capacitive key cell structure and switchcore matrices formed therefrom
IPC: H03K17/967
Filed: 1989-08-30
Abstract: In a matrix of capacitive key cells (A1,A2,B1,B2) of 
the type including a contact switch (20) in series with a 
key cell capacitor (21), an intracell coactive loading 
capacitor (22) is connected between ground and the junction 
(23) of the contact switch (20) with the key cell capacitor 
(21). A matrix of key cells (A1,A2,B1,B2) so formed is 
self-referencing, in that the need for a separate reference 
capacitor to load a sense line (50) is eliminated. 
Instead, loading is provided intrinsically by the effect of 
the intracell coactive loading capacitors (22) acting 
through multiple key cells (A1,A2,B1,B2) connected to a 
sense line (50).

Title: Bias circuit for a subranging analog to digital converter
IPC: H03M1/06
Filed: 1989-12-07
Abstract: Through first and second external terminals (T₂, 
T₃), fixed potentials are applied to both ends of a 
first stage of ladder resistor network. A second stage 
of ladder resistor network is connected at one end to a 
second transistor (Q₂). The first external terminal 
(T₂) is connected to a first transistor (Q₅) through a 
resistor (R M ), the resistor (R M ) and the resistors of 
the first and second stage of ladder resistor networks 
being of the same kind. A positive input terminal of an 
operational amplifier (1) is connected to a node (A) 
between the resistor (R M ) and the first transistor (Q₅). 
A negative input terminal of the amplifier (1) receiving 
a reference voltage is connected to the second external 
terminal (T₃). The first and second transistors (Q₂, 
Q₅) are driven by the output signal of the amplifier 
(1). The amplifier (1) cooperates with the first 
transistor (Q₅) such that a potential at the node (A) is 
equal to the potential of the reference voltage. As a 
result, a current (I₂/M (M = constant)) flowing through 
the resistor (R M ) is proportional to a current (I₂) 
flowing through the first stage of ladder resistor 
network. Since the current, which is based on the 
operation of the second transistor (Q₂), flows into the 
second stage of ladder resistor network, the current 
flowing through the first transistor (Q₅) is propor­
tional to a current (I₃) flowing through the second 
stage of ladder resistor network.

Abstract: A printing apparatus has a removable developing unit 
including a casing (118), for holding developer powder, and a 
developing roller (102) for use in developing an electrostatic latent 
image, formed on an image support member (101) of the apparatus, by 
transferring developer powder to the latent image, the said image 
support member (101) being supported at opposite ends thereof in the 
apparatus by first and second holding members (109, 110).  
     First and 
second locating members (116, 117), secured respectively to the said 
holding members (109, 110), are provided with respective grooves 
(116a, 117a), for receiving respectively first and second mounting 
members (115, 114A) disposed at opposite axial ends of the developing 
roller (102) such that a desired operative positioning of the 
developing roller (102) in the apparatus can be achieved by inserting 
the said first and second mounting members (115, 114A) into the said 
grooves (116a, 117a) at respective first ends thereof and moving those 
mounting members (115, 114A) along the grooves (116a, 117a) into 
engagement with abutment portions (116b, 117b) at respective opposite 
ends of those grooves (116a, 117a).  
     Since the shaft of the 
developing roller (102) is itself used to locate the developing unit 
with respect to the image support member (101), the error in the gap 
between the developing roller (102) and image support member (101) can 
be reduced, and/or fitting tolerances relaxed, as compared with prior 
art printing apparatus.

Title: Integrated circuit having a configurable terminal pin
IPC: H03K19/0175
Filed: 1989-02-14
Abstract: A terminal pin (28) of an integrated circuit can be 
controlled in three ways to function as an input or an 
output pin. A logic circuit (16, 20, 23, 26) permits 
the pin to be synchronously enabled as an output 
terminal under software control. The circuit also 
permits the pin to be asynchronously enabled as an 
output terminal under control of a signal applied to 
another pin of the integrated circuit. The circuit also 
permits continuous control of the terminal as an input 
pin. Maskable bits stored in registers (18, 22) and 
configuration bits stored in register (25) affords 
additional flexibility in establishing which of the 
three ways the terminal pin will be controlled.
