Title: Semiconductor integrated circuit capable of preventing occurrence of erroneous operation due to noise
IPC: G11C16/12
Filed: 1989-12-12
Abstract: A semiconductor integrated circuit includes a cir­
cuit block (13) whose operation is controlled by a 
inverted control signal whose significant potential 
level is set at a ground potential, and a wiring (12) 
for transmitting a control signal for controlling the 
operation of the circuit block (13). An inverting cir­
cuit (14) provided near the circuit block inverts the 
control signal and then supplies the inverted signal to 
the circuit block (13) via a wiring (15). The inverter 
includes a first capacitor (25) connected between the 
power source terminal and a node (23) which is set at a 
high potential level in the inverter circuit (14) when 
the control signal is set at the non-significant poten­
tial level and a second capacitor (30) connected between 
a ground potential terminal and a node (28) which is set 
at a ground potential level when the control signal is 
set at the non-significant potential level.

Patent EP-0326334-A3 (EP)
IPC: H02H3/093
Filed: 1989-01-25
Abstract: A circuit breaker with over-temperature protector 
and low error I²t calculator is provided. The over-­
temperature protector includes a fixed current source 
(Q016, Q111, Q112, Q113, Q114) which exists within the 
control circuit of the circuit breaker (10) to provide 
current to resistive elements (R100, R018) to produce a 
voltage thereacross which increases with a positive temper­
ature coefficient as the surrounding temperature increases. 
The resistor is connected to the base-to-emitter circuit of 
a transistor (Q123). The base-to-emitter circuit has a 
minimum firing voltage which decreases with an increase in 
ambient temperature. The value of the resistive element, 
the amount of current provided by the fixed current source 
and the transistor base-to-emitter minimum firing voltage 
are chosen to cause a firing circuit (Q833) for the opening 
apparatus (FST) of the circuit breaker to be actuated when 
a predetermined ambient temperature which may be 90°C, for 
example, is obtained. There is also provided an active 
memory device (Q766) which is utilized to discharge a 
capacitor (C2) with a time constant which approximates the 
heat dissipating time constant associated with a conductor 
(L1, L2, L3) to be protected by the circuit breaker in 
question. The capacitive element is charged initially by a 
small charging current (iLDT) which is related to the 
square of the current flowing through the conductor to be 
 
 
protected. Thus, the voltage developed across the capaci­
tor is related to the amount of heat built up in the 
conductor to be protected and when this voltage reaches a 
predetermined level, the circuit breaker mechanism is 
actuated to cause the circuit breaker contacts (K1, K2, K3) 
to open to thus prevent further heat accumulation in the 
conductor to be protected. However, if the current which 
is causing conductor heat accumulation ceases or decreases, 
the need for opening the circuit breaker decreases accord­
ingly. In order to account for the heat dissipation 
associated with the previous situation, the active memory 
element is utilized to discharge the capacitor as men­
tioned. However, during the charging operation, the 
presence of the active memory element would provide a 
parallel path for the charging current for the capacitor 
this would introduce an error into the voltage across the 
capacitor. Therefore, the active element is disconnected 
from the circuit by an appropriate sensing current (R763, 
R4104, R762, Q764, Q784) so that during a charging opera­
tion for the capacitor none of the charging current is lost 
through the memory device.

Title: Thickened moulding resin composition
IPC: C08L67/06
Filed: 1989-02-16
Abstract: Sheet molding compounds are thickened (or 
maturated) via "in situ" formation of polyureas made from 
aromatic primary diamines with reduced basicity and 
diisocyanates. The molding compounds, which can option­
ally contain mineral fillers such as chopped glass fiber, 
are generally based upon unsaturated polyester resins 
having a high percentage of hydroxyl end groups, polymer­
izable vinyl compounds such as styrene, and the like. 
The thickened compositions are tack-free and compression 
moldable after less than one day, typically after less 
than several hours, into permanently shaped, strong rigid 
articles, such as automotive body parts. A viscosity 
plateau is reached and maintained by the maturated com­
pounds of the present invention for extended periods of 
time, e.g., several weeks.

Patent EP-0381466-A3 (EP)
Title: Improvements relating to the production of concrete beams or the like
IPC: B28B7/24
Filed: 1990-01-31
Abstract: The present specification discloses an apparatus 
and method for producing concrete beams for use in the 
construction industry. Concrete beams are 
conventionally made in suitable moulds in a factory, 
the beams being removed from the mould and transferred 
to the construction site. However, removal from the 
mould and transit can cause the beams to be damaged, 
besides adding to the production cost.  
     The present invention provides an apparatus which 
is manhandlable without the need for lifting gear, and 
which can be used on site, thereby reducing production 
cost and the possibility of damage. The apparatus 
comprises a number of vertical supports (5) between 
which horizontal support members (7) extend. Elongate 
mould members (17) rest generally horizontally on the 
support members (7), abutting one another so as to 
define a number of adjacent, parallel, generally 
U-shaped channels (19). In use, concrete is poured 
into the channels (19) and after hardening the mould 
members (17) are separated, it being a relatively 
easy operation to release the L-shaped mould members 
(17) from the beams with little, if any, damage.

Abstract: The appts. (10) includes a laser driver (16) that receives low speed and high speed digital and analogue input signals (12,14), and biases and modulates the laser diode (22) accordingly. The laser driver (16) receives and responds to input from a feedback circuit (36, 38), which includes an average power control portion (36), and a modulation power control portion (38). The average power control portion (36) of the feedback circuit generally determines the DC component of the laser diode output, and compares it to a reference average. The modulation power control portion (38) of the feedback circuit generally determines the max and min peaks in the laser diode output, averages them and compares the average to the DC component of the laser output from the average power control portion (36). The laser diode (22) is then driven by the laser driver (16) in response to the comparisons.

correction layer (800, 900, 50) includes a plurality of
optical correction regions (802, 902, 62) centered over the
gaps (604, 806), and a plurality of optically transparent
