Main part of the vacuum furnace at Okaya Heat Treatment Industry

Okaya Heat Treatment Industry (Okaya City, Nagano Prefecture) has invested about 60 million yen to installa medium-sized atom nitriding system manufactured by Plasma Research Institute (Tenpaku Ward, Nagoya City). When hardening the surface of high-speed steel (HSS), etc., this equipment can perform surface nitriding treatment uniformly even on objects with complicated shapes, with almost no secondary compounds in the diffusion layer of nitrogen atoms. Mr. Takizawa, president of Okaya Heat Treatment Industry, said, "In order to stably apply hard coatings on tools, etc., further secondary processing is necessary, but such technology is also being established. In the future, the company plans to expand its business to include the hard coating base treatment of cemented carbide tools and high durability surface treatment of blades.

    Technology to etch Kai semiconductor with fluoroplastic instead of CFC gas

    Technology to etch Kai semiconductor with fluoroplastic instead of CFC gas

    The established technology will be used for dry etching, thin film formation and cleaning of silicon. Easy-to-handle gases such as argon and nitrogen are irradiated onto solid fluoropolymers to generate fluorine-containing gas. The gas is then used for plasma treatment. Using a proto device with electrodes developed for special equipment, the company irradiated nitrogen gas and etched a glass substrate, and was able to etch 40 nanometers in one minute. The company plans to achieve an etching speed of 200 nanometers for commercialization. Plasma is an unstable state in which electrons have been removed from molecules, and it modifies the surface of materials, improving adhesion and cleaning effects.

      Atmospheric pressure plasma system for Kai Semiconductor

      Atmospheric pressure plasma system for Kai Semiconductor

      Kai Semiconductor (Shimogyo-ku,Kyoto City) will release on December 2 an atmospheric pressure plasma system "GaCo (get a command of)," which enables plasma processing of curved surfaces, which has been difficult to do at atmospheric pressure. By placing it on the object to be processed and tracing it, even curved shapes can be processed efficiently. The dielectric barrier discharge, which discharges at a low temperature, does not burden or affect the object. The standard model, the 200, processes 100 millimeters per second with a processing width of 200 millimeters and a maximum width of 1,100 millimeters. Plasma treatment is promising for use in pre-treatment to improve adhesion in the tempered glass coating process. In the case of curved surface treatment, vacuum plasma treatment is inefficient due to batch processing, and solvent treatment requires large equipment.

        HIGHTECH SEIKO's newly installed vacuum furnace.

        HIGHTECH SEIKO's newly installed vacuum furnace.

        Hitec Seiko (Hanamigawa-ku, Chiba City) has introduced a new type of vacuum heat treatment furnace. The new furnace reduces the processing time to about 10 hours, 30% less than the previous model. By increasing the utilization rate and providing more space in the furnace, the company aims to stabilize the quality. We will increase the sales of the heat treatment business to 270 million yen in the fiscal year ending March 2020, up 12.5% from the previous fiscal year. The company has newly introduced the PQ-65 pressure-cooled horizontal vacuum furnace manufactured by IHI Mechanical Systems (Koto-ku, Tokyo), with a view to entering the aerospace field in the future. The maximum processing capacity of the vacuum furnace is 400 kilograms, which is the same as the conventional furnace, but the processing time can be reduced from 15 hours with the conventional furnace.
