Filed: 2005-12-21
Abstract: An apparatus for controlling a fail of a cooling apparatus in ion implantation equipment is provided to stop an ion implantation process when a cooling apparatus fails by generating an interlock in an ion implanting process chamber. A cooling apparatus detects a heat exchange fail state to generate a fail detection signal. A controller(32) receives the fail detection signal from the cooling apparatus and blocks control power to stop generation of an ion beam. The cooling apparatus includes a fail detecting part(40) and a first LED(light emitting diode). The fail detecting part can detect the heat exchange fail state to generate the fail detection signal. The first LED turns on by the fail detection signal generated from the fail detecting part to display the heat exchange fail state. The controller can include a first relay, a second LED, a second relay and a beam control part(42). The first relay supplies control power. The second LED displays the heat exchange fail state by the fail detection signal generated from the fail detecting part.

Title: Method and device for cooling ultrasonic transducer
Inventor: HIELSCHER HARALD
IPC: G10K11/00
Filed: 2003-11-19
Abstract: The invention relates to a method and a device for cooling ultrasonic transducers. The inventive device is characterised in that it consists of at least one piezo stack (4) and at least two cylindrical transducer bodies (5), which together with the piezo stack (4) form an lambda/2 oscillator. In multiple transducer assemblies, two respective transducer bodies (5) can be combined to form a common transducer body (6) and the transducer bodies (5, 6) comprise flow channels (7), through which pressurised coolant can flow. The inventive method for cooling ultrasonic transducers is characterised in that the body of the ultrasonic transducer is traversed and/or surrounded by a pressurised coolant. This enables the heat that is generated in the transducers to be directly dissipated by convection. In addition the inventive elements enable the creation of a large common contact surface between the transducers and the coolant. The heat dissipation achieved is substantially more effective than in known methods and the inventive elements thus guarantee a high-performance continuous operation.

Title: Apparatus and method for scheduling of downlink voip packets in mobile communication base station system
Inventor: KIM HAN SEOK
IPC: H04L12/66
Filed: 2006-01-16
Abstract: A downlink voice packet network packet scheduling device in a mobile communication base station system and a method thereof are provided to measure delay time when delay is started if the transmission delay of VoIP(Voice over Internet Protocol) packets occurs, and to previously set packet loss in a suitable ratio, thereby reducing the transmission delay of the VoIP packets. When packets of a voice packet network are received, network transmission delay time is calculated by using a difference of time stamp values in case of base station arrival time and generation of the packets(301-305). If the packets refer to packets to be currently scheduled, queuing delay time is calculated by using a difference between base station departure time and the base station arrival time of the packets(307-313). Packet transmission delay time is calculated by using a sum of the queuing delay time and the calculated network transmission delay time(315). It is checked whether the calculated packet transmission delay time satisfies a predetermined threshold value, and if so, transmission of the packets is determined, and if not, dropping of the packets is determined(317-323,325).
