ISRO's Polar Satellite Launch Vehicle PSLV-C38 recently launched the 712 kg Cartosat-2 Series Satellite along with 30 copassenger satellites from Satish Dhawan Space Centre SHAR, Sriharikota. This event marked thirty ninth consecutively successful mission of PSLV. One of the 30 co-passenger satellites carried by PSLV-C38 was CE-SAT 1, a fifty-kilogram (110 lb) microsatellite built by Canon Electronics, Japan. Canon will use the spacecraft to demonstrate a high-resolution imaging system in orbit, with a ground resolution of up to one meter (3 feet). About 60% of components of the satellite are manufactured by Canon, and the company targets a 100% inhouse production in the near future. The company also plans to sell the satellites, related components and the image data collected by the CE-SAT 1. The small-size satellites are expected to be sold for 1 million yen (approximately).
Toshiba Corp. on July 11 had a meeting with its main banks about the negotiation of the sale of its semiconductor memory business with the Japan-US-South Korea ally led by Innovation Network Corp. of Japan (INCJ). The top management of Toshiba explained the negotiation is stalemated because the ally has a difficulty on the roles of SK Hynix of South Korea, which seems to have a stronger interest in NAND type flash memory technology than the other have earlier expected because SK is behind Samsumg in the mass production for NAND memory while it has know-how in DRAM production, which lacks in Toshiba and thinks the company has a merit to join the ally and commit to Toshiba Memory’s production more aggressively. Toshiba revealed it has started to negotiate again with Western Digital and Hon Hai Precision. WD has proposed the acquisition by allying with U.S. fund Kohlberg Kravis Roberts (KKR & Co.), INCJ and Development Bank of Japan. Toshiba wants to decide the sale of Toshiba Memory by the end of March, 2018 in order to have excessive liabilities two years in a row which is to lead to the company going private.
