Storage tanks today can hold upwards of 10, 20 or even 30,000 tons of liquid that must be protected from the elements and from pollution to safeguard it for use in water, waste water, emergency fire protection and high purity industrial processing applications. Not only are tanks being built to hold their contents more safely and securely than ever before, but they are expected to do it for longer and in more challenging operating environments where steel, concrete and fibreglass tanks need secure roofs that can withstand expansion and contraction caused by factors such as increasing climatic and load variations. A challenge facing developers and operators of buildings and processing plants for industrial and municipal uses is ensuring their top structures can flexibly cope with internal movement from climatically induced expansion, contraction and wind and rain forces, while also coping with production stresses caused by heavy and changing loads, vibration and other factors encountered within diverse industries. Relevant industries can include mining and energy, oil and gas, ports and infrastructure, food and beverage, primary processing, manufacturing, materials handling, water and waste water utility and emergency services. A cost-efficient solution to many such issues is offered by Hercules Engineering through its range of Herculon Type D Tank Top Bearings (HLD/TT) Bearings, which are custom-designed for easy installation under roof beams of tank tops and other lighter structures including some building roofs. These low-friction easy-slip bearings are particularly useful where loads are relatively small but both lateral and uplift forces need to be accommodated, says Mr David Booty, Manager, Hercules Engineering (a division of Cut to Size Plastics). “Light but strong and flexible tank tops are now widely employed to protect tanks and their contents from external pollution ranging from flora, fauna, dust and droppings and water-borne impurity. The bearings used under […]

The job of maintenance supervisors is to get the maintenance work completed on time, on budget and safely! They can be popular. They can be great communicators. They can be inspired trainers. They can be great repair people. But these things alone do not make successful maintenance supervisors. They are not successful maintenance supervisors unless they can keep the machines running, the fleet rolling and the occupants warm in the winter. When does an active supervisor look like when he is no longer bogged down in an office doing paperwork? Active supervision occurs when a supervisor spends substantial time on the shop floor helping workers solve problems. As strange as it might sound, on the psychological level a supervisor might have to be both mother (nurturing and supportive) and father (strict and tough) to members of the crew. Active supervision encompasses several roles: • Ongoing performance monitor: The supervisor knows how long each job should take and checks it periodically throughout the day. A four-hour job issued in the morning should be done by the lunch break. When the jobs fall behind, the experienced supervisor thinks about how best to intervene. In some cases it might be logistical help, helping with equipment, or providing guidance about how to proceed. • Paperwork compliance officer: The accuracy of all analysis is derived from the work order. If the work order is complete and accurate then decision-making and root cause analysis become dramatically easier. Supervisors audit paperwork and return it when it is deficient. They should always look at work orders on the floor and ensure entries are being made at the same time as the activity occurs, not at a later time. • Obsessive-compulsive PM monitor: A supervisor reinforces the rule: “Do the PM as it is written.” A related issue is […]

TOKYO, July 15, 2015 – Tanaka Holdings Co., Ltd. today announced that Electroplating Engineers of Japan, Limited (EEJA), which operates the Tanaka Precious Metals’ plating business, has developed, and launched from July 15, the RAD-Plater cup-type[1] ultra-compact plating laboratory equipment for semiconductor wafers, which achieves equivalent films to mass-production machines. The RAD-Plater is ultra-compact laboratory equipment for manufacturing 2 to 8 inch semiconductor wafers. Measuring 800 mm wide and 700 mm deep, it is smaller than mass production machines and can operate on only compressed air and the 100 volt power of general equipment. In addition to gold, silver, palladium, copper and nickel, it can use a wide variety of plating solutions including alloys and lead-free solutions, and at 10 liters or less of solution, it uses about half the plating solution required by dip-type machines, which also reduces experimentation costs. The RAD-Plater uses an EEJA-manufactured Stir Cup[2] and delivers mass-production level plating quality through uniform and bubble-less film thickness and superior filling of deep vias[3]. It also enables reduced plating time by using a high current density[4] achieved with an increased ion supply. Even though the RAD-Plater is laboratory equipment, it achieves a level of plating equivalent to that of mass-production machines, which enables early problem-solving in the development stage for mass production issues such as expected yield, and enables trouble-free rollout to the mass-production line. This is the world’s first cup-type plating laboratory equipment for manufacturing semiconductor wafers, using 10 liters or less of plating solution and handling 8-inch wafers. Many development divisions of manufacturers with mass-production plating lines would have previously contracted out the plating solution experimentation work to equipment manufacturers and others for evaluation, but purchasing a RAD-Plater and conducting experiments in-house now enables a considerable reduction in development lead times. Other customers would have previously […]
