Abstract: An X-ray simulator has an X-ray source and collimator connected to the end of a cantilevered horizontal arm mounted on a gantry that rotates about a horizontal axis and extends along a patient supporting table. The horizontal arm has an asymmetrical cross section that causes the arm and therefore the X-ray source and collimator to deflect by differing amounts as the gantry rotates. To compensate for the varying displacement of the X-ray target point and to adjust the position of the target point along the rotation axis of the gantry, the collimator is pivoted in one direction or the other in accordance with the amount of rotation of the gantry axis.

Abstract: A communication system (10) for the transfer of small digital message blocks and large digital message blocks. A plurality of nodes (26, 38, 30, 32, 34, 36) are coupled to a common wideband communication channel (12) capable of facilitating the transfer of small digital message blocks and large digital message blocks. One of the nodes (26-36) is a master node controlling the communication on the communication channel (12) by selectively polling the other of the plurality of nodes (26-36). The communication system (10) has a first protocol for the transmission of small digital message blocks and a second protocol for the transmission of large digital message blocks. The master node establishes a polling priority (66) for each ofthe plurality of nodes and polls those with a higher polling priority more frequently than those with a lower polling priority. The master node allows the one node being polled to communicate over the channel (12) of either a small digital message block or a large digital message block. Further the master node adapts the polling priority (66) for each of the nodes based upon a predetermined algorithm.

Abstract: A brake control system (l0) for an aircraft is provided wherein an antiskid control circuit (24) is adapted to release brake pressure upon sensing undesirable wheel speed excursions. Connected in parallel to the antiskid control circuit (24) is a torque control circuit (38) which senses the instantaneous torque at the brake (l8) of each wheel (l4) and causes a release of brake torque by releasing brake pressure when the torque is sensed to have exceeded a threshold level. The torque signal above such threshold will also cause a reduction in gain of the antiskid control circuit (24), in order to maintain high antiskid braking performance for those conditions which cause higher than normal torque to be developed by the brake.

Abstract: There are disclosed a method and an apparatus for forming disk-wheel like formed parts, in a manner that the vertical mold axis of a metal mold cavity (8) corresponds to the axis of rotation of a disk wheel to inject hot molten metal from the bottom in the mold axis direction. A control mode of the injection speed comprises: a first phase to allow an injection speed when the hot molten metal has reached the inlet (8A) of the metal mold cavity (8) to be low, a second phase to allow an injection speed from the time when the hot molten metal passes a disk-wheel hub equivalent portion (8B) of the metal mold cavity until it passes the greater part of a disk-wheel rim portion (8D) thereof via a disk-wheel disk portion (8C) thereof to be, at the end portion of said rim equivalent portion, equal to a speed corresponding to a lower speed or less, which corresponds to a gas discharge ability of a degassing unit (12) provided in association with the metal mold, and a third phase to close a discharge valve (22-26) of the degassing unit (12) after the hot molten metal has passed the greater part of the rim equivalent portion (8D) to continuously carry out injecting operation, thus allowing the hot molten metal to be completely filled into the metal mold cavity (8). Thus, this permits gas within the metal mold cavity (8) to be effectively discharged at any time without causing gas to be included into hot molten metal, thus making it possible to easily provide nest-free, high quality formed parts.

Inventor: IWAMURA SOICHI
IPC: H04N7/14

Abstract: In a method for multiplex transmission of audio and video signals according to the present invention, first the video signal is separated into a luminance signal and a chrominance signal, then a luminance carrier is frequency-modulated with the luminance signal while the chrominance signal is down converted to a lower band, and such audio signal, frequency-modulated luminance carrier and down converted chrominance signal are multiplexed by frequency division to be transmitted. Consequently, in comparison with the conventional transmission method which executes direct frequency-modulation of the video signal, the bandwidth necessary for transmission of the frequency-modulated luminance carrier becomes narrowerto eventually facilitate mutt- ichannel transmission. And if any amplitude-modulated component is generated in the carrier components in the multiplex transmission by the harmful influence from interference induced by external radio waves through the cable or from metallic members used to fix the cable, there occurs no deterioration in the picture quality since such component is removed on the receiver side prior to demodulation of the frequency-modulated video carrier. Accordingly, satisfactory picture transmission can be performed without the necessity of any additional co-axial cable for video signal transmission. And it is also possible to utilize an existing interphone cable for transmission of the video carrier. Since no impediment is caused despite any multipath reflection or interference of medium waves, cable installation can be achieved easily regardless of such harmful influence from medium waves or multipath reflection, hence realizing simplified and low-cost transmission of multiplex audio and video-carrier. Furthermore, when installing a door camera in addition to the interphone system used to baseband transmission of audio signal, a desired operation is rendered possible by additionally furnishing the existing interphone equipment with a video carrier transmitter/receiver and the video processors.

Abstract: A device for controlling the idling operation of an internal combustion engine is disclosed which can prevent any abnormal increase in RPMs during the idling of the engine even if a control unit outputs an abnormal signal to an actuator so as to cause a throttle valve to excessively open from a preset position. The idling-operation controlling device comprises: an actuator for controlling the opening degree of a throttle valve during the engine idling operation; an actuator position sensor for sensing the operating position of the actuator; a control unit adapted to receive the output signals from an engine RPM sensor, a water temperature sensor which senses the temperature of engine cooling water and the actuator position sensor to control the operation of the actuator in a manner such that the opening degree of the throttle valve is adjusted to an appropriate level thereby to control the RPMs of the engine during idling to a predetermined value in response to the sensed temperature of the cooling water; a position limiter adapted to output a limit signal to the control unit when the output signal from the actuator position sensor exceeds a preset upper limit which corresponds to the sensed temperature of the cooling water; and an actuator-stopping element adapted to stop the operation of the actuator when the limit signal is input from the position limiter to the control unit and when the control unit outputs to the actuator an output signal which operates the actuator in a direction to increase the engine RPMs. In another embodiment, the actuator-stopping element is replaced by an actuator-limiting element which not only performs the same operation as that of the actuator-stopping element but also operates the actuator in a direction to decrease the engine RPMs to a prescribed level.
