Question: New Zealand DSJ class locomotive was first assembled by what company that produced diversified products like information technology and communications equipment and systems, electronic components and materials, power systems, industrial and social infrastructure systems, consumer electronics, household appliances, medical equipment, office equipment, as well as lighting and logistics.? 
Context: The New Zealand DSJ class is a class of diesel-electric shunting locomotive used on the New Zealand rail network.  The class has a very similar overall design to the DSG class, but is instead single-engined, has a cab that is offset from the centre, and is both shorter and lighter than its twin-engined counterpart.  The first DSJ was assembled in Japan by Toshiba Heavy Industries, the same company who built the EO class electric locomotives.  The remaining four were assembled at the former Addington Workshops in Christchurch. Hitachi, Ltd. (株式会社日立製作所 , Kabushiki-gaisha Hitachi Seisakusho ) (] ) is a Japanese multinational conglomerate company headquartered in Chiyoda, Tokyo, Japan.  It is the parent company of the Hitachi Group ("Hitachi Gurūpu") and forms part of the DKB Group of companies.  Hitachi is a highly diversified company that operates eleven business segments: Information & Telecommunication Systems, Social Infrastructure, High Functional Materials & Components, Financial Services, Power Systems, Electronic Systems & Equipment, Automotive Systems, Railway & Urban Systems, Digital Media & Consumer Products, Construction Machinery and Other Components & Systems.

Along with its headquarters and design operations based in the Hsinchu Science Park in Taiwan, Holtek operates worldwide with a wide range of global agents.  Holtek's design focus is in both 32-bit and 8-bit microcontroller development with the company having around 650 employees.  Holtek also designs and provides peripheral semiconductor products such as remote control, telecommunication, power management, computer peripheral, and memory devices.  Holtek's device application area is concentrated in the consumer product field such as household appliances, computer peripheral products, remote controllers, leisure products, medical equipment as well as industrial controllers.  Holtek microcontrollers are in home appliances including brands such as Philips, Siemens, Märklin and Japanese brands such as Futaba and Sony. KEMET Corporation was set up in 1919 and now is based in Simpsonville, South Carolina.  The company produces many kinds of capacitors, such as tantalum, aluminum, multilayer ceramic, film, paper, polymer electrolytic, and supercapacitors. Capacitors are electronic components that store, filter, and regulate electrical energy and current flow.  As an essential passive component used in most circuit boards, capacitors are typically used for coupling, decoupling, filtering, oscillating and wave shaping and are used in communication systems, data processing equipment, personal computers, cellular phones, automotive electronic systems, defense and aerospace systems, consumer electronics, power management systems and many other electronic devices and systems (basically anything that plugs in or has a battery).  The company also manufacturers a variety of electronic components such as, AC line filters, EMI cores and filters, flex suppressors, relays, metal composite inductors, ferrite products, and transformers/magnetics.  The product line consists of nearly 5 million distinct part configurations distinguished by various attributes, such as dielectric (or insulating) material, configuration, encapsulation, capacitance (at various tolerances), voltage, performance characteristics and packaging. Yongsan Electronics Market is a retail area in Seoul, South Korea.  Comprising over 20 buildings, housing 5,000 stores that sell appliances, stereos, computers and peripherals, office equipment, telephones, lighting equipment, electronic games and software, videos and CD's.  A variety of electronic components for constructing computers and other items can also be found.  Korean-made products generally cost 20% less here than other retail outlets, while imported items can be as much as 50% cheaper. Consumer electronics or home electronics are electronic (analog or digital) equipments intended for everyday use, typically in private homes.  Consumer electronics include devices used for entertainment (flatscreen TVs, DVD players, video games, remote control cars, etc.), communications (telephones, cell phones, e-mail-capable laptops, etc.), and home-office activities (e.g., desktop computers, printers, paper shredders, etc.).  In British English, they are often called brown goods by producers and sellers, to distinguish them from "white goods" such as washing machines and refrigerators.  In the 2010s, this distinction is not always present in large big box consumer electronics stores, such as Best Buy, which sell both entertainment, communications, and home office devices and kitchen appliances such as refrigerators.  Consumer electronics stores differ from professional audio stores in that the former sells consumer-grade electronics for private use, whereas the latter sells professional-grade electronics designed for use by audio engineers and audio technicians. Cyclops Steel (also known as Universal-Cyclops and for one of its main subsidiaries as Detroit Steel) was a steel company based in Pittsburgh, Pennsylvania.  It was founded in nearby Bridgeville, Pennsylvania in 1908 as Universal Rolling Mill Company and merged with Cyclops Steel Company founded in 1884 of the Western Pennsylvania city of Titusville in 1936.  Cyclops Steel marketed to industries such as aerospace, automotive, business machines, chemical processing, communications equipment, construction, electronics, farm machinery, food processing equipment, home appliances and cutlery, industrial machinery, marine equipment, medical equipment, drilling and mining equipment, military equipment, power generation equipment, rail transportation, sports equipment and tools, ties and fixtures. Kyocera Corporation (京セラ株式会社 , Kyōsera Kabushiki-gaisha ) (   ) is a Japanese multinational electronics and ceramics manufacturer headquartered in Kyoto, Japan.  It was founded as Kyoto Ceramic Company, Limited (京都セラミック株式会社 , Kyōto Seramikku Kabushiki-gaisha ) in 1959 by Kazuo Inamori and renamed in 1982.  The company has diversified its founding technology in ceramic materials through internal development as well as strategic mergers and acquisitions.  It manufactures industrial ceramics, solar power generating systems, telecommunications equipment, office document imaging equipment, electronic components, semiconductor packages, cutting tools, and components for medical and dental implant systems. Toshiba Corporation (株式会社東芝 , Kabushiki-gaisha Tōshiba ) , commonly known as Toshiba and stylized as TOSHIBA, is a Japanese multinational conglomerate headquartered in Tokyo, Japan.  Its diversified products and services include information technology and communications equipment and systems, electronic components and materials, power systems, industrial and social infrastructure systems, consumer electronics, household appliances, medical equipment, office equipment, as well as lighting and logistics. SMT (surface mount technology) component placement systems, commonly called pick-and-place machines or P&Ps, are robotic machines which are used to place surface-mount devices (SMDs) onto a printed circuit board (PCB).  They are used for high speed, high precision placing of broad range of electronic components, like capacitors, resistors, integrated circuits onto the PCBs which are in turn used in computers, consumer electronics as well as industrial, medical, automotive, military and telecommunications equipment.
Answer: Toshiba Corporation
