In Brief

• The Semiconductor Equipment and Materials Institute (SEMI) has incorporated the SafetyBus p safety sensor bus technology into its E54 suite of standards, making Safetybus p the only safety network technology qualified for use in the semiconductor industry.

Yaskawa has developed a high-precision XY stage based on air bearings and coreless linear motors which, it says, will offer repeated positioning to an accuracy of 10nm for semiconductor applications. The maintenance-free stage requires no lubrication and can travel at up to 50mm/s.

Camcon Technology, the UK developer of a novel binary actuation technology, has licensed the technology to the Birmigham-based engine and transmission manufacturer Powertrain, for use "intelligent" engine valves, which are expected to boost the efficiency, performance and economy of vehicle engines. The actuators will allow each valve to be controlled independently and to recover energy.

DaimlerChrysler has chosen an Ethernet-based safety network to manage the safety-related monitoring and shutdown of hazardous areas in the body shop of its Dusseldorf plant. The safeEthernet system is based on standard Ethernet technology, but accelerates the transmission of safety-related data to 100Mb/s. The Category 4 system, was developed by HIMA, which is supplying the plant`s safety control equipment.

Mitsubishi Heavy Industries claims to have developed the world`s largest electrically-powered injection moulding machine. The machine, with a clamping force of 3,000 tonnes, is said to cut car bumper moulding times by 30% compared to conventional hydraulic models. A pressure waveform control technology allows moulding at low pressures, reducing burrs.

Wago and the cable distributor Belcom have joined the AS-Interface Expert Alliance which was set up recently to provide free support to AS-i users in the UK via Freephone number (0800 169 2331).
