With 27,000 people in 28 countries, the NSG Group services customers in more than 130 countries. NSG produces high-performance glass and glazing solutions in three business areas, with total revenue of 626.7 billion (5.2 billion) in its 2015 fiscal year (ended March 31, 2015). Architectural and Building Products (40% of sales), producing products such as solar control glass, self-cleaning glass, and glass for solar applications; Automotive (50 percent); and Technical Glass (10 %). For the fiscal year, the company spent $8.2 billion ($66 million) on research and development.

The Architectural division’s operating results improved over the previous fiscal year as a consequence of cost reductions realized as a result of the group’s restructuring initiative, as well as improving market circumstances in North America. The Automotive segment’s revenues increased marginally, owing to a weaker Japanese yen, while earnings fell due to unfavorable market conditions. The Technical Glass division saw a drop in income, owing in part to lower pricing for some goods. Thin glass for display revenues have also suffered as a result of increased competition.

6. Kyocera Corp.

Takeda Tobadono-cho, Fushimi-ku

Kyoto 612–8501, Japan

Chairman: Tetsuo Kuba

Kyocera employs about 70,000 people across its 226 global group enterprises. For the fiscal year ended March 31, 2015, consolidated net sales totaled $1,527 billion ($12.7 billion), up 5.5% from the previous fiscal year. Kyocera earned $2.1 billion in advanced ceramics/glass-related sales in the 2015 fiscal year, according to Elly Yoshikawa, Kyocera’s deputy manager of Corporate Communications. (This figure includes revenue from non-ceramic items, but excludes revenue from the company’s Fine Ceramics and Semiconductor Parts businesses). Total revenue in the company’s consolidated Fine Ceramics sector climbed 13.3 percent year over year, while total revenue in the consolidated Semiconductor Parts segment increased 16%.

Kyocera is stepping up its development of parts for next-generation semiconductor fabrication equipment, which includes equipment for next-generation, larger-dimension silicon wafers, in the industrial machinery industry. The company is working on camera modules for rearview detection and collision avoidance for the automotive market, which is expected to grow in demand due to new safety standards. At the same time, Kyocera is focusing its research and development efforts on ceramic parts for diesel engines that help reduce CO2 and other exhaust gas emissions.

In the environment and energy sector, Kyocera is focusing on solid oxide fuel cell (SOFC) systems and components, which have a lot of potential as new energy supply systems for a low-carbon society, as well as LED-related goods, which are becoming more popular in lighting applications.

In the digital consumer electronics sector, demand for multifunctional smartphones and tablet computers that are also smaller and thinner continues to develop. Electronic components utilized in such equipment are becoming smaller, while semiconductors are becoming more densely integrated, in accordance with this trend. Demand for quicker, higher-capacity infrastructure is increasing in the information and communications network business. Kyocera is aiming to develop new high-value-added products that use its material, design, and stacking expertise to increase its company in response to these market developments. In the ceramic package business, the company is developing high-strength, high-rigidity, ultra-small and thin ceramic packages that use micro-wiring, as well as ceramic packages for optical communications that can operate at higher frequencies.

According to Kyocera’s financial prediction, total consolidated revenue will increase by 4.8 percent in the fiscal year ending March 31, 2016. (This projection includes both ceramic and non-ceramic business segments.) There are no separate forecasts for particular company segments).

The Canadian government granted Morgan’s Composites and Defense Systems subsidiary two body armor development contracts in October 2014, focusing on a next-generation lightweight, low-profile, higher-performing design for personal armor plates. Morgan announced the move of its Composites and Defense Systems company to Burlington, Ontario, in the same month, in order to expand its capabilities in advanced composite hard armor, soldier systems, vehicle armor, lightweight vehicle technologies, and aerospace armor.

Morgan stated in March that it had extended its design and manufacturing capabilities for ceramic pockets that store medical device circuits. The company’s improved CNC machining skills, according to reports, allow it to produce alumina ceramic pockets with tighter tolerances and shorter lead times. Morgan uses a ceramic injection mold technology to create higher-strength yttria-stabilized zirconia pockets for extremely small medical devices with thinner walls.

Following increased demand from the oil and gas sector, Morgan announced a significant investment in its capability to construct high-specification hydro cyclone liners at its site in Rugby, Warwickshire, in July. To meet rising demand from oilfields in Southeast Asia and Africa, the investment included the hiring of five new personnel as well as the expansion of kiln and grinding capacity.
