Patent number: 6201777Abstract: An apparatus for discriminating optical disks has an optical pickup provided with an objective lens having an effective numerical aperture of 0.55 to 0.65, which can compatibly reproduce information from a CD and an SD. The apparatus discriminates presence/absence of waveforms of two focus error signals detected when the effective numerical aperture of the objective lens is set at 0.55 to 0.65 and 0.20 to 0.45 respectively in a process of performing focus servo control, thereby discriminating various types of optical disks from each other. Thus, optical disks having different substrate thicknesses, different track pitches, different minimum pit lengths and different reflectivity can be quickly and simply discriminated from each other.Type: GrantFiled: February 17, 1999Date of Patent: March 13, 2001Assignee: Sanyo Electric Co., Ltd.Inventors: Yoichi Tsuchiya, Seiji Kajiyama, Yasuyuki Kanou, Shuichi Ichiura, Koichi Tada, Masami Shimizu, Toshio Harada

Patent number: 5905891Abstract: A programmable controller (PC) which converts PC instructions directly into targeted CPU instructions, not into a macroprogram format, and stores them as an execution file. The PC stores restoration information for ladder display together with the CPU instructions, whereby the number of program steps to be executed is reduced and a ladder display can be provided. The PC also converts PC instructions written in the ladder language into restoration information restorable to the ladder language and generates them as a main processing restoration information file, then converts the PC instructions directly into targeted CPU instructions, not into a macroprogram format, on the basis of the restoration information file, and stores them as an execution file independently of the main processing restoration information file.Type: GrantFiled: January 23, 1995Date of Patent: May 18, 1999Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Toshio Harada, Kazuhiro Kudo
