Patent EP-0262705-A3 (EP)
Title: Hierarchical synchronization method and arrangement for the nodes of a meshed telecommunication network
IPC: H04J3/06
Filed: 1987-08-31
Abstract: In a mesh telecommunication network in which a hierarchic synchronization method is used for synchronizing the clock pulses of exchanges in such network, a class identification is assigned to the clock pulses of each echange corresponding to a hierarchical order of all the exchanges in the network. To maintain synchronization regardless of changes in the network configuration or failure of interconnecting lines, a synchronization identification is additionally assigned to each exchange. Each exchange transmits its class and synchronization identifications to the exchanges connected thereto, and all the identification received at any exchange are compared to determine the exchange connected thereto having the highest class identification and the highest synchronization identification in such class. The sychronizing clock pulses of such highest order exchange are then used for synchronization. Each exchange may also add to its identifications a mark to distinguish different operating conditions of the network. The reception at each exchange of the class and synchronization identifications transmitted by exchanges connected thereto is effected within presettable time intervals.
Patent EP-0239249-A3 (EP)
IPC: H03C1/16
Filed: 1987-02-25
Abstract: An RF-AM transmitter includes a pulse amplifier respon­
sive to a pulse width modulated (PWM) signal derived in 
response to an information signal. A low pass filter converts 
pulses derived by the power amplifier into a variable amplitude 
signal that is DC coupled to a power supply for an RF amplifier. 
An amplifier system including the pulse and RF amplifiers 
has stray capacitance coupled to a modulator which derives 
the PWM signal; the stray capacitance lengthens narrow 
modulator output pulses so they are excessively long. The 
amplitude of only the narrow pulses is reduced by a resistor-­
capacitor timing circuit in series with a switch to substantially 
preserve the narrow pulse area. The switch provides a low 
impedance path from the timing circuit to a reference potential 
terminal when current initially flows in the circuit during pulse 
transitions and throughout the length of each of the short 
duration pulses. Thereby, the power amplifier is forward 
biased but not driven into saturation during the short duration 
pulses. The switch provides a higher impedance path from the 
timing circuit to the reference potential terminal after the 
transition has elapsed, enabling the power amplifier to be 
saturated during pulses longer than the short duration pulses. 
The RF power amplifier tube has a tendency to load the 
power amplifier tube out of saturation during wide pulses. 
The amplitude of the wide pulses is maintained substantially 
constant by a resistor shunted by an inductor between the 
modulator and the power amplifier.

Abstract: A method of making a cartridge-type 
fuse involves forming a subassembly comprising 
an inner insulating housing preferably made of 
a transparent glass material, end cap 
terminals at the ends of the housing and leads 
extending axially therefrom. A preferably 
transparent encapsulating body is molded 
around the inner housing which covers, seals 
and physically interconnects the exposed 
exterior surfaces of the inner housing, 
terminal means and a portion of each lead 
adjacent to the terminal means. The molding 
operation is preferably carried out by 
unwinding a roll (11) of the fuse subassemblies (A) 
having their leads (5) secured between a pair of 
carrier strips (10) wound up with the subassemblies 
into a roll and supported on a rotatable 
supply reel (12). The reel is unwound in 
intermittent steps to bring a predetermined 
number of the subassemblies between pairs of 
mold cavity-forming elements (18A, 18B) initially 
separated and then brought together around the 
fuse subassemblies to mold the encapsulating 
bodies (B) therearound. The completed 
encapsulated fuses carried between the carrier 
strips are then would upon a take-up roll (12') for

Filed: 1988-03-23
Abstract: A multistage digital filter for producing an 
output data sequence in response to elements of an 
input data sequence includes a multiplier for 
multiplying elements of the input data sequence by 
selected coefficients to produce product terms. An 
accumulator sums product terms to produce elements

multiplier and accumulator produce accumulated sums 
in response to the first stage output sequence to 
provide a second filter stage output sequence. In 
a similar fashion, each filter stage output 
sequence is fed back to the multiplier as the input 
sequence to the next filter stage until the output 
sequence of the last filter stage is produced.

Title: Semiconductor memory device
IPC: G11C29/04
Filed: 1989-02-25
Abstract: Semiconductor memory device and method for implementing 
wordline redundancy with no access penalty. A redundant 
word decoder compares an incoming address signal with 
a list of defective addresses and, in response to the 
comparison, produces at least one comparison signal to 
control the propagation of a redundant driver signal 
along at least one redundant wordline. A main trigger 
receives the comparison signal and, in response 
thereto, triggers the firing of a main wordline driver 
to produce a main driver signal. The main wordline 
driver and the redundant word decoder are responsive 
to opposite states of the comparison signal, such 
that, for a given comparison signal, only one of the 
main driver signal and redundant driver signal is 
applied to a memory array.
Patent EP-0337396-A3 (EP)
Title: Two-wire detection system having self-diagnosis means
IPC: H03K17/95
Filed: 1989-04-11
Abstract: The detection system comprises a sensor (1) and a controller (2) which are connected by two wires (3a, 3b). The sensor can take more than two states as opposed to conventional detection systems. According to this arrangement, for instance, a small leakage current exists even when the sensor is in normal off state, and, therefore, electric current in the range of I1 to I2 flows even in normal off state. On the other hand, electric current of (I3) to (I4) flows in normal on state. When there is a wire breakage, no electric current flows. Conversely, when there is a shortcircuiting, electric current exceeding (I4) flows. Electric current in the range of (I3) to (I4) corresponds to an unstable state which is neither normal on state nor normal off state. Thus, by distinguishing the level of the electric current flowing through the wires, by using suitable electric current level detecting circuit, which of the level classes it belongs to, a state signal corresponding to the result of this distinguishing process can be outputted for self-diagnosing purpose.
