Abstract: A mixed signal which contains a noise is input. Then, the signal is inverted and amplified by an inverting amplifier (4) which has a high gain, and attenuated by a attenuator (5) in order to generate an inverted phase signal. In a mixer (6), the input signal and the inverted phase signal are added, and output. Since the inverted phase component of the noise is added to the noise, the noise in the mixed signal is canceled. For the voice signal, an amplified inverted signal is generated by an inverting amplifier (4). However, the amplitude thereof is restricted due to a high gain. Since the amplitude is restricted, a level of the inverted phase signal is lower than a level of a voice signal. Even if the voice signal and the inverted phase component are added in the mixer (6), the voice signal is output almost thoroughly.

Abstract: In an X-ray tube (31) with a hydrodynamic slide bearing, an electron beam is caused to strike the focal point track area F on its rotary anode, which then emits X rays. An X-ray emission control device (29) that sets the conditions for emitting the X rays stores as data the rises and drops in the temperature at the electron beam incident point and the other part on the focal point track surface of the anode. On the basis of the data, the input permission or inhibition conditions for the X-ray tube at every moment are calculated and the resulting conditions are displayed on a display unit (61). As a result, it is possible to perform a computing process in advance to determine whether or not X rays can be emitted under specific conditions without permitting the rotary anode in the X-ray tube with a hydrodynamic slide bearing to melt and then display the results, thereby enabling a safe, efficient photographing control.

Abstract: There is disclosed a fluctuation torque cancellation apparatus which positively cancels a torque fluctuation developing on an input shaft or an output shaft of a motion conversion apparatus for converting a continuous rotational motion of the input shaft into a predetermined-type rotational motion (e.g. intermittent rotational motion) of the output shaft. A torque compensation cam 5, fixedly mounted on a rotation shaft 4, continuous rotates when the rotation shaft 4 rotate, and a cam surface, formed on a peripheral surface of the torque compensation cam 5, reciprocally moves a slider 7 in a cylinder 9 while rotating a cam follower 6. As a result, a coil spring 12, mounted within the cylinder 9, is compressed and expanded, so that a pressing force of the cam follower 6 against the torque compensation cam 5 is varied, thereby cancelling a fluctuation torque applied to the rotation shaft 4, thus effecting a torque compensation for the motion conversion apparatus 2. When it is desired to vary the torque compensation value, the air is supplied from an air source 16 to an air chamber 17 in the cylinder 9 to add a pressing force by the air, so that the compensation torque is exerted on the rotation shaft, using both of the spring pressure and the air pressure.

Abstract: A non-breakdown triggered electrostatic discharge
(ESD) protection circuit (11) comprising a voltage
divider circuit and a SCR (22). The voltage divider
comprises a capacitor (17) and a resistor (18). The
voltage divider connects to a pad of an integrated
circuit and generates a trigger voltage for enabling the
SCR (22) when an ESD event is applied to the pad. A
worst case ESD voltage transient is used to calculate a
trigger voltage for the SCR (22). The trigger voltage is
selected at a voltage below where damage to the
integrated circuit occurs. The SCR (22) is designed to
have a turn on time constant that prevents normal signal
levels from triggering the SCR (22).

Abstract: When a laser beam interacts with a workpiece to be welded by the beam, a plume of optical radiation is generated. An apparatus and method is disclosed in which radiation from the plume is received back through a beam delivery path comprising optical elements (L1,L2) having chromatic aberration. This alters the focus of different spectral bands of the plume radiation and a discriminating aperture is formed by a face of an optical fibre (3). After passing through the fibre, the plume radiation is separated from any laser radiation and the respective powers of the different spectral bands are measured (5). By subtraction, an error signal is obtained which is used to control the focus of the laser beam.
