JIDECO
A picture in another thread posted today shows an electrical relay (rear window defroster, I think) with the manufacturer's name ('JIDECO') stamped on the side of the cover. I didn't recognize that company, but figured that the 'J' maybe stood for 'Japan' and the 'ECO' for 'Electric Company'. The 'I' and the 'D' were a puzzle, though, so I did a bit of on-line searching. The answer lay in the corporate website of another Japanese manufacturer, 'Mitsuba' (wiper motors) that came up in some of the hits I got using, 'Japan + company + JIDECO' as my search string. Hiding in the 'History' page on Mitsuba's site was this entry:
2007: The Jidosha Denki Kogyo Co., Ltd. (Jideco) merged with Mitsuba.
A bit more poking around revealed that Jidosha Denki's old website was www.jideco.co.jp. However, that site now just shows a message saying that Mitsuba and Jidosha Denki have 'merged' and providing links to the Mitsuba website.
An old Bloomberg listing for Jidosha Denki said that they manufactured wipers, power windows and power lock systems and provided a single address: 1760 Higashi-Matanocho, Totsuka-ku, Yokohama, Kanagawa, 245-8510 Japan.
So they were probably located not too far from the Nissan assembly plant in Yokohama.
Entering that address into Google Maps shows that it's now listed as, 'Mitsuba Corporation Yokohama R&D Centre'. Street view shows us what the former Jidosha Denki h/q looks like today:
Hard to tell whether there's any manufacturing facilities at the back of the property. The front part looks like strictly admin and engineering. The back part may just be lab space.
Digging back into Jidosha Denki's history, I found this not-happy story from 1998 in a business trade newspaper:
"Jidosha Denki Kogyo has unveiled plans to restructure its operations and those of its subsidiaries, a move which will result in the company's workforce being reduced by 30% to 700 staff by 2000. The company plans to close down three subsidiaries, with production being switched to overseas bases in India, China and Indonesia. The restructuring will leave the company to provide wiper systems, control devices and motors in Japan... Jidosha Denki Kogyo will move all of its mass production of motors for power windows and windscreen wipers to subsidiaries in the Philippines and China for its products to be more cost-competitive to its main client, Nissan Motor. Jidosha Denki Kogyo's two Japanese plants will stop production of these products by March 2002, and will specialise instead in making prototypes and some spare parts, and in assembling complete wiper units."
Then in 2002:
"Jidosha Denki Kogyo (JIDECO) will have a 35.8% stake acquired by fellow electric motors and wiper systems maker, Mitsuba, affiliate of Honda. JIDECO will issue 15 mil third-party shares on 07 January 2003 as part of the deal. The companies hope that the deal will enable them to improve their cost competitiveness by working together on purchasing, product development and manufacturing. The deal will result in Nissan and Hitachi reducing their stakes in JIDECO to 14.6% and 13.8% respectively."
And in 2004:
"Jidosha Denki Kogyo, automobile control parts maker, will invest around Y500 mil to restart production at its plant in Tomioka in Japan's Gunma Prefecture. It stopped production at the plant in 2002, but has now decided to use the plant as a major site to improve production technology. It has installed a new assembly line for seat-use operations, which is already in operation; and will transfer another such line from its plant in Kikugawa by September 2004. By March 2005, it will transfer a line for motors used in power windows from Kikugawa to Tomioka."
And, finally, this, from the Mitsuba 2006 Annual Report:
"The Company has decided to merge with its wholly owned subsidiary Jidosha Denki Kogyo Co., Ltd., effective April 1, 2007. The Company and Jidosha Denki Kogyo, having been closely working, have agreed on the merger to enhance their synergy as an integrated group and seek greater management efficiency. The Company will be the "surviving entity" under the provisions of Japanese Corporate Law following the absorption and merger of Jidosha Denki Kogyo Co., Ltd. and its subsequent dissolution."
And that was the end of JIDECO.
