Patent EP-0382970-A3 (EP)
IPC: F16K3/02
Filed: 1989-10-30
Abstract: An improved gate valve has a body (12) with a chamber 
(14) and an inlet (16) and an outlet (18) extending there­
through into said chamber, a gate (20) mounted for 
reciprocation in said chamber between open and closed 
positions, a pressure responsive actuator (30) having a 
housing (34), a piston (36), a connection to the gate and 
an actuating stem extending from the housing, and a 
supplemental actuator (42) having a connection to the 
actuator housing, an operating stem (44) connected to the 
actuating stem (46). The operating stem (44) has a shoulder 
(92) facing in the direction opposite to the direction of 
closing movement of the gate. Roller levers (64) are 
pivotally mounted to be in engagement with the exterior of 
the operating stem and a spring (72) urges the roller levers 
into tight engagement with the operating stem, the roller 
levers pivoting on engagement with the stem shoulder (92) to 
exert a closing force on the stem. In a modified form of 
the invention, lever-roller assemblies are provided within 
the actuator to increase the closing force of the piston 
during the last portion of its stroke by changing the 
spring force provided by the actuator spring.

Title: Electret condenser microphone
IPC: H04R19/01
Filed: 1989-10-31
Abstract: An electret condenser microphone includes a cup-­
shaped metallic case (11) having an apertured end wall 
(11a), a tubular metal ring (12) received in the metallic 
case (11), a vibratory diaphragm (13) having on its one 
surface a deposited metal film (13a) and bonded to an end 
face of the tubular metal ring (12) in confronting relation 
to the end wall (11a) with an air gap (19) defined therebe­
tween, and a condenser composed of a movable electrode and a 
fixed counter electrode, the fixed counter electrode com­
prising at least a part of the end wall (11a) of the metal­
lic case (11) while the movable electrode comprises the 
vibratory diaphragm (13). Partly because the end wall (11a) 
of the metallic case (11) serves as the fixed electrode, and 
partly because the vibratory diaphragm (13) is bonded to the 
end face of the metal ring (12), the number of the compo­
nents of the microphone is relatively small. With this 
small number of components, the microphone is simple in 
construction and can be manufactured at a low cost, and 
further has a relatively large rear cavity (14) behind the 
vibratory diaphragm (13), which improves the sensitivity of 
the microphone.

Patent EP-0381131-A3 (EP)
Title: Power controller with voltage-controlled circuit breaker
IPC: H02H3/24
Filed: 1990-01-30
Abstract: A power controller (100) comprises a manually-on circuit 
breaker (112) having an electrically-actuable trip coil (142) 
which enables the circuit breaker (112) to be tripped-off 
electrically. The circuit breaker (112) is connected to a 
voltage source and provides operating voltage to a power outlet 
(124, 126). A line voltage monitor (116) provides a voltage 
indication (FH, FL) to a logic control circuit (118) when the 
operating voltage moves outside a predetermined range estab­
lished by setting upper and lower operating voltage limits. 
In response to receiving such a voltage indication (FH, FL), 
the logic control circuit (118) deenergizes a relay (K1), 
thereby connecting a charged capacitor (C13) to the tripping 
coil (142) of the circuit breaker (112) to cause the breaker 
(112) to be tripped-off even when the voltage to the circuit 
breaker (112) drops to zero volts. Other signals provided to 
the control logic circuit (118) also cause the deenergizing 
of the relay (K1) controlling the circuit breaker tripping 
capacitor (C13). A logic control timing circuit enables the 
circuit breaker (112) to latch on when it is manually turned 
on and while the operating voltage is stabilizing in the line 
voltage monitor (116). The power controller apparatus (100) 
may include at least one switched power outlet (124) connected 
for receiving operating voltage from the circuit breaker (112) 
and includes a switch (122) for enabling the switched power 
outlet (124) to be selectively turned on and off while the 
circuit breaker (112) is tripped on.

Abstract: A DRAM including a peripheral circuit (3) and a 
memory cell (2) has a fin structure capacitor (6) 
overlying and separated from a transfer gate transistor 
(6) by a silicon nitride layer (18). A conductive layer 
(13A) which forms an electrode (13) of the capacitor (6) 
the silicon nitride layer (18A) is removed from above the 
peripheral circuit (3) before contact windows (31,32) are 
opened up through insulating layers (16,17) to the 
surface of a semiconductor element (22) formed in the 
peripheral circuit (3). This improves the aspect ratio 
of the contact windows and prevents breakage of

Title: Process for the connection of timber elements and connection device for them
IPC: E04B1/48
Filed: 1991-09-19
Abstract: To produce a tension- and shear-resistant connection of two beams, in particular in the form of glued laminated timber members, with mutually crossing grains of the two beams to be connected, in a process for the connection of such timber elements a bore is produced through the face of the cross-cut end of the first beam and a spindle made of metal and equipped with a thread is bonded into the bore by means of epoxy resin, an end portion of the spindle projecting above the face. On connecting the two beams, the end portion of the spindle reaches through a corresponding bore in the second beam, at the end of which is formed a counterbore for receiving a nut which can be screwed onto the end of the spindle. A ring made of metal is arranged in the connection plane of the two beams concentrically to the spindle in such a way that one ring half extends into an annular groove in the face of the first beam and the other ring half extends into a corresponding annular groove in the contact face of the second beam. After tightening the nut on the spindle, a tension- and shear-resistant connection of the beams is produced. <IMAGE>

Filed: 1995-10-31
Abstract: A costas loop includes a comparator, and a BPSK-modulated
signal which is converted into a binary signal
by the comparator is latched by a D-FF according to an
oscillation signal from a VCO. An output of the D-FF
becomes a demodulated signal. On the other hand, a
phase-difference between the BPSK-modulated signal and
the oscillation signal is detected by a phase-comparator,
and the phase-difference is applied to the VCO via a loop
filter. An oscillation frequency of the VCO is thus
controlled according to a phase-comparison result.
