Patent EP-0183196-A3 (EP)
IPC: G06F13/20
Filed: 1985-11-21
Abstract: A bus system is disclosed in which stations having a 
message to send request access to a parallel bus and an 
arbitrator responding to the requests connects the transmit­
ters of the stations to the bus in sequence. The words of a 
message placed on the bus respectively represent the 
address of the station to which the message is to be 
delivered, the address of the sending station, and data. A 
station asserts a signal on one control line in response to its 
address being on the bus and asserts a signal on another 
control line if it cannot receive a message. Whether the entire 
message is placed on the bus or not by the sending station 
and loaded into the registers of the receiving station depends 
on whether or not their signals are asserted. An external data 
transfer means places signals to a station on another parallel 
bus on an external bus. The external bus is in the form of a 
loop so that the message eventually returns to the station 
that sent it. Bits are added to certain of the words in the 
message when it starts around the loop and the logic level of 
these bits when they return to the station that sent the 
message indicates whether the station to which the message 
was sent exists and, if so, whether or not the message was 
delivered.

process for preparation of a zirconium-base alloy structural 
member includes, in addition to subjecting a zirconium-base 
alloy to a final plastic working step, a step of coating its 
surface with the element. There can be obtained a zirconium­
base alloy structural member exhibiting a high corrosion 
resistance and having a high ductility.

Patent EP-0205122-A3 (EP)
IPC: G06F11/34
Filed: 1986-06-06
Abstract: An apparatus for counting occurrences of a plurality of 
events characterized by unique event numbers includes a 
random access memory (16) for storing event count numbers 
at addresses corresponding to the event numbers. The mem­
ory (16) is addressed by an event number as the associated 
event occurs, and the event count number stored at such 
address is read and latched to an input of an adder (28). The 
adder (28) increments the latched event count number and the 
incremented event count number is then written back into the 
memory (16) at the current event number address. A buffer 
(36) is provided to store the current event number whenever 
the adder (28) overflows as a result of a count. Several such 
event numbers may be stored in the buffer (36) for subse­
quent retrieval by an external controller thereby permitting 
the controller to determine when an event has been counted a 
fixed number of times and to increment its own internally 
stored count at a slower rate than the rate at which data is 
applied to the prescaler.

Abstract: The specification and drawings intend to disclose the 
technique in a method of driving a liquid crystal display panel 
which is suitable to display a multivalue image such as a tele­
vision image or the like, whereby the image signal is inverted 
by integer times of the horizontal sync signal and applied to 
the source lines, the same inversion control signal is also syn­
chronously applied to the common opposite electrode, 
thereby remarkably reducing the driving voltage of the source 
lines. In this manner, a high-speed CMOS device of a low with­
standing voltage can be used as an integrated circuit to drive 
the source lines.

Abstract: Apparatus and method for ultrasonically bonding a web 
utilizes ultrasonic bonders having respective anvil (59) and 
sonotrode (29) components which are synchronously orbited with 
each other and with the rotation of a rotatable drum which 
carries the web (24) of material to be bonded. One of the anvil 
and sonotrode components is orbited exteriorly of the drum (20) 
and the other interiorly of the drum and they are brought 
into facing alignment through openings (54) in the drum to clamp 
segments of the material therebetween during passage 
through a bonding segment of the travel path of the web 
about the drum. The bonder component orbiting exteriorly 
of the drum is axially translated away from the anvil along 
the drum in order to provide clearance for withdrawal of 
the bonded material from the drum. In this manner, an 
ultrasonic bonder may clamp the material at a single 
location for a large segment of its travel along the 
rotation path of the drum, thereby attaining a bonding time 
not limited entirely by the travel speed of the web.
