Patent EP-0851562-A3 (EP)
Inventor: MENICHELLI STEFANO
IPC: H02M3/07
Filed: 1997-12-23
Abstract: A voltage multiplier circuit for integrated circuits, comprising two
mirrored sections driven by control signals (PH00, PH01, PH0_P; PH10,
PH11, PH1_P) generated by a logic circuitry which receives, as input
signals, an enable signal (en) and a clock signal (clk), wherein each
mirrored section includes N stages and each stage comprises a capacitor
(C00, C01, C02; C10, C11, C12) having a lower terminal and an upper
terminal, the lower terminal is connected to a first switch (INV0, NCH00,
NCH01; INV1, NCH10, NCH11) that, in closed condition, couples the
lower terminal of the capacitor to ground (GND), said lower terminal of the
capacitor being additionally connected to a second switch (INV0, PCH00,
PCH01; INV1, PCH10, PCH11) that, in closed condition, couples the
lower terminal of the capacitor to the supply voltage (Vpp), as far as the
first stage is concemed, or to the upper terminal of the capacitor of the
previous stage, the upper terminal of the capacitor is connected to a third
switch (NCH02, NCH03, NCH04; NCH12, NCH13, NCH14) that, in closed
condition, couples the upper terminal of the capacitor to the supply
voltage (Vpp), the upper terminal of the capacitor (C02; C12) of the last
stage is connected to a last two-terminal switch (Q0; Q1 ) that, in closed in
condition, couples the upper terminal of the capacitor of the last stage to
the output of the voltage multiplier; said control signals directly or
indirectly drive said switches such that, when the voltage multiplier is
enabled (en = 1), at a rate determined by said clock signal (clk), each
mirrored section in alternated times is switched over from a charging
phase to a discharging phase, so that while a mirrored section is in
charging phase, the other one is in discharging phase and vice versa;
when a mirrored section of the circuit is charging phase, the last switch
(Q0;Q1) and all second switches thereof (INV0, PCH00, PCH01; INV1,
NCH10, NCH11) are in open condition, while its first (INVI0, NCH01; 
INV1, NCH10, NCH11) and its third switches (NCH02, NCH03, NCH04;
NCH12, NCH13, NCH14) are in closed condition, so that all capacitors of
this circuit section are parallel connected between the supply voltage
(Vpp) and ground (GND) and are charged up to said supply voltage
(Vpp); when a mirrored section of the circuit is in discharging phase, all its
first (INV0, PCH00, PCH01; INV1, NCH10, NCH11) and third switches
(NCH02, NCH03, NCH04; NCH12, NCH13, NCH14) are in open
condition, while its last switch (Q0; Q1) and all its second switches (INV0,
PCH00, PCH01; INV1, PCH10, PCH11) are in closed condition, so that all
capacitors are serially connected with one another, the lower terminal of
the capacitor (C00; C10) of the first stage being connected to the supply
voltage (Vpp) and the upper terminal of the capacitor of the N-th stage
being connected to the output of the voltage multiplier; when the voltage
multiplier is disabled (en = 0), both mirrored sections of the circuit are in
charging phase.

Abstract: To provide a connector provided with a retainer which can prevent a retainer
insertion hole from being exposed to the outside and has a strong force for
retaining terminal fittings. 
     A retainer 30 is rotatable in a housing 10 about an insertion portion 33.
When the retainer 30 is rotated to its lock position, lock projections 32 provided
on the insertion portion 33 lock the terminal fittings 20. Since the retainer 30 can
directly lock the terminal fittings 20 in this connector, the terminal fittings 20 can
be retained with a strong force. Further, since a retainer insertion hole 31 is
formed in the front surface of the housing 10, it is not exposed to the outside by
being covered by a mating connector. In other words, the inventive connector has
advantages of both side retainer type and front retainer type connectors of prior
art and retains the terminal fittings 20 with a large force while being designed to
be watertight.

frequency, each base station and terminal station have
directional antennas respectively, and a base station has
direction-determining patterns for setting a direction of an

using the same frequency use different direction-determining
patterns from each other, and remote base stations repeatedly
use the same direction-determining patterns. The
direction-determining pattern has a correlation between a
timing obtained by equally dividing a frame for a communication
line by a number of direction-determining patterns and each
antenna direction, and a communication slot is allocated based
on a timing decided according to the table to a communication
line with a terminal station positioned at a particular

Abstract: A lighting system for a discharge lamp includes an inverter circuit
(5, 5 a , 5 b , 5 c  or 5 d ) to which is connected a load circuit (6, 6 a  or 6 b )
including a resonant circuit of an inductor (12) and a capacitor (11) in
serial connection, with a discharge lamp (13) connected in parallel with
the capacitor. An inversely frequency dependent voltage is applied between
the lamp electrodes according to a predefined resonance characteristic
such that the resonance frequency ( f   o ) is less than a discharge start
frequency ( f   2 ) at which the lamp is to start glowing. For lighting up
the lamp the frequency of the inverter output voltage is changed from a
first frequency ( f   1 ) that is higher than the discharge start frequency to
a second frequency ( f   3 ) that is less than the resonance frequency. 
     If the lamp accidentally goes off, the current flowing through the
load circuit will advance out of phase with the inverter output voltage,
possibly resulting in the destruction of inverter switch or switches ( Q   1 
and  Q   2 ) due to overcurrent. This danger is precluded by constantly
monitoring the phase of the load current and, in event the load current
is found to be in phase advance, by making the inverter output frequency
higher than the resonance frequency of the resonant circuit and
thereby delaying the phase of the load current.

Abstract: A plasma density information measuring method capable of easily measuring
the plasma density information over the long term, a probe for measuring the plasma
density information, and a plasma density information measuring apparatus are
disclosed. A measuring probe is set such that a tip end of a glass tube of the measuring
probe is brought into contact with plasma PM to be measured. High-frequency power
sent through a coaxial cable is supplied to the plasma PM from a loop antenna through a
wall of the tube, and reflection power of the high-frequency power is received by the
loop antenna to obtain a counter frequency variation of reflection coefficient of the high-frequency
power. In the obtained reflection coefficient, a portion thereof in which the
reflection coefficient is largely reduced is a peak at which strong absorption of high-frequency
power is caused due to the plasma density. The plasma density can be
obtained from the plasma absorption frequency.
