Parseval-Sigsfeld kite balloon. Parseval-Sigsfeld kite balloon (in German Parseval-Sigsfeld Drachenballon) was a type of non-rigid military observation balloon, designed in 1898 by August von Parseval and Hans Bartsch von Sigsfeld. Its aerodynamic shape and the air capsule ensured a stable position thanks to the force of the wind, in a similar way to how kites are stabilized; for this reason it was known as the kite balloon (in German Drachenballon).

Aircraft was widely used as a main observation balloon type by the Central Powers armies in World War I warfare.

Design 

August Parseval, German airship factory owner and Hans Bartsch von Sigsfeld, German military officer, had been experimenting with different balloon shapes since 1893, previously using spherical balloon shapes, which had been unstable in windy weather. Around 1898 they constructed a balloon with an elongated shape, equipped with stabilizers, later replaced by suitably shaped air chambers. Under the pressure of the wind (the permissible speed for the balloon was 10 m/s) it would settle into a stable position, with the canopy raised about 30–40° in the direction of the wind.

A two-person observation balloon had a tether with a volume of 760 m3. The envelope with a diameter of 6.68 meters had a cylindrical shape with semicircular bottoms. In the rear part of the envelope there was a stabilizer with a characteristic phallic shape, which was filled with air under wind pressure. Volume compensation was regulated by ballonet.

Operational history 
Positive flight characteristics pursued high command of the Imperial German Army to apply Parseval-Sigsfeld kite balloons for military service, as the Austro-Hungarian Army did so. Type was then produced and used in large quantities during World War I not only by the German or Austro-Hungarian troops, but also by the French, who undertook its minor production based on captured examples under the designation Ballon Captif type G and the modernized type H.

Two balloons of this type were taken over by the Poles in January 1919 in the airship hall at Winogrady in Poznań. One of them was used for the first balloon ascent in independent Poland, which took place on July 23, 1919. As an outdated equipment it was then used for training observers at the Officers' Aeronautical School . In 1920, the balloons were replaced by Caquot type R balloons imported from France.

Cobalt ochre. Cobalt ochre, cobalt-ochre (Cobalt ocher in American English) or ochre of cobalt () — a common name that was widely used in mining and craft environments until the end of the 19th century for at least two cobalt-containing secondary ore minerals: asbolane and erythrite. They were often used with the addition of a clarifying color adjective or a clarifying mineral form adjective to avoid confusion.

Meanwhile, at the beginning of the 19th century, the number of cobalt ochres looked much more impressive. For example, Robert Jameson, relying on numerous studies of his predecessors (from Werner to Haüy), divided cobalt ochres into four classes: black cobalt-ochres, brown cobalt-ochres, yellow cobalt-ochres and red cobalt-ochres. In turn, each of the color forms of ochre had two or three varieties. Black cobalt ochre had two main forms, which were widely distributed in the mines of Europe: earthy black cobalt-ochre and indurated black cobalt-ochre. Brown or yellow-brown cobalt-ochres varied in composition, sometimes being a mixture of black and yellow cobalt ochres. Yellow cobalt-ochres often appeared in association with various forms of red cobalt-ochres, as well as nickel ochres. Finally, red cobalt ochre was known in three mineral forms: earthy red cobalt-ochre, radiated red cobalt-ochre, and slaggy red cobalt-ochre.

At the same time, Jameson believed that cobalt ochres have a lot in common and can be classified as a special class of minerals. ″The Black, Brown and Yellow Cobalt Ochres, and other similar minerals, ought to be arranged together, and form a particular order by themselves. In the mean time, we place them beside the Red Cobalt, on account of their being often associated with that mineral″. However, from a chemical point of view, Jameson and his contemporaries reduced the entire diversity of cobalt ochres to two groups of chemical compounds of cobalt: oxides (asbolane) and arsenates (erythrite) in different morphological forms of crystallization and with a different set of impurities.

Essential minerals 
 Asbolane — a secondary mineral of the oxide class with the formula (Со,Ni)O•MnO2•nH2O, consisting of hydrous oxides of manganese, cobalt and nickel. Forms sooty, earthy masses (asbolan from the  — soot) of dirty colors from yellowish-brown to bluish-black.
 Erythrite — a secondary mineral of the arsenate class with the ideal formula Co3(AsO4)2•8(H2O), consisting of  and usually also containing impurities of nickel, iron, zinc, magnesium and calcium. Due to its bright color, it is used as an indicator of nearby cobalt ores, and sometimes also native silver.

Lasertec Corporation. Lasertec Corporation is a Japanese company based in Yokohama that specializes in the development, manufacture and distribution of inspection and measurement systems used primarily in the semiconductor industry. In its niche, the company is the global market leader. Lasertec pursues a fabless strategy and outsources production to subcontractors, allowing it to concentrate on research and development. Lasertec's shares are listed on the Tokyo Stock Exchange and are included in the Nikkei 225 index.

History 
The company was founded in 1960 as Tokyo ITV Laboratory, and started out developing and designing X-ray cameras for specialized medical equipment. In the 1970s, the company began to expand into inspection systems for photolithography in the semiconductor industry. In 1979, a branch was opened in San Mateo and in 1980 in Düsseldorf. In 1986, the company was renamed Lasertec Corporation and Lasertec U.S.A., Inc. was founded as an American subsidiary in San José. In 2004, the company's shares were listed on the Jasdaq Shōken Torihikijo and in 2012 a secondary listing was made on the Tokyo Stock Exchange.

In 2017, an inspection system for EUV (extreme ultraviolet lithography) masks was unveiled. Lasertec was the first company worldwide to offer such a product commercially. The associated lithography machines are manufactured by the Dutch company ASML and Lasertec's measurement systems are used to check whether the manufactured semiconductors are ready for production, giving Lasertec a global monopoly in this niche of the semiconductor industry.

In 2020, Lasertec won Intels annual supplier award.

In 2022, the company announced the construction of the Lasertec Innovation Park in Yokohama as a new research and development center.

Thanks to the global AI boom, Lasertec's shares rose by almost 1800 percent between 2019 and 2024, which is why Lasertec was included in the Nikkei 225 index in 2023. This rise in the share price made Lasertec the most traded stock on the Tokyo Stock Exchange.

In July 2024, the short-seller Scorpion Capital accused the company of fraudulent behavior. The announced next-generation EUV product would be a "hoax" and the announced new research and development facility actually deserted.

Products 
Lasertec Corporation designs and markets specialized measurement and inspection instruments. These systems are used primarily in the semiconductor industry to ensure the quality of EUV masks, wafers and other components. Lasertec also develops inspection systems for photomasks used in the production of flat-panel displays and laser microscopes.
