Title: Optical disk and optical disk tracking method
Inventor: NAKANE KAZUHIKO
IPC: G11B20/12
Filed: 1996-06-24
Abstract: PROBLEM TO BE SOLVED: To correctly detect a tracking polarity by arranging an identification signal on the border between adjacent groove and land in the identification signal area between the recording sector of an adjacent groove and the recording sector of an adjacent land. SOLUTION: A tracking error signal is judged by two threshold levels shown with a chain line on a tracking error signal (b) while using a window comparator. Whether a sector is the sector of a groove track or the sector of a land track is discriminated by the polarity of the tracking error signal having the amplitude of not less than the threshold level. The polarity of a control system is set so as to apply a tracking to the center of the groove in the area of a groove sector and to apply a tracking to the center of the land in the area of a land sector. The identification signal appeared in a period when an ID detecting window signal (d) becomes an OPEN is detectcd. In reading information, the identification signal shown in (e) is read out by using a reflected light from phase pits. Then, a land/groove changeover is performed by detecting the information.

IPC: H04B7/26
Filed: 1996-06-25
Abstract: PROBLEM TO BE SOLVED: To simplify the operability and to improve the battery service life by conducting power on/off operation while an accessory pen is contained. SOLUTION: A pen 17 used to touch a displayed part of a menu on a operation panel 15 with an LCD display device 11 for making an operation is contained in a container section 18 inside the receiver when the pen is not in use. The container section 18 has an insertion hole and is provided with a detection section 16 to identify a pen container state consisting of a push switch at the side around the bottom and when the pen is contained, a contained state detection signal is informed to a control section 4. The control section 4 recognizes the contained state of the pen based on the contained state detection signal to control power on/off. That is, when the pen is extracted while the power supply is deenergized, the power is energized and when the pen 17 is contained while the power is energized, the receiver power supply is deenergized.  Thus, without operating the main power switch, the power supply/ interruption is attained to each part of the power automatically.

The billet is subjected to impact working such as by shot blasting, air hammering or the like to apply work strain thereto. The cooling is then returned to an ordinary cooling rate and the billet is slowly cooled by the heat regenerated from the inside to accelerate precipitation of carbonitride such as AlN, NbC or the like thereby preventing precipitation of said carbonitride at the grain boundary between ferrite and austenite and forming the finer austenite grains. The ductility of the cntinuous casting billet is improved and the generation of a flaw like crazing on the surface is prevented.

Abstract: PURPOSE:To perform instantaneously the periodical switching of a remote switchboard and to ensure the smooth exchange processing after said switching, by providing a memory copy device between a using system and a spare system to copy directly the untransmitted information of a station of the remote side to the spare system. CONSTITUTION:When a switching indication is given, both a master station information transmitter SLC0 and a remote station information transmitter RSLC0 copy the untransmitted information to be given to the remote side station as well as the untransmitted information to be given to a central controller CC0 and a remote switchboard RPOS to information transmitters SLC1 and RSLC1 of a spare system (1 system) via memory copy devices MC and RMC. Under such conditions, the exchange processing is made waiting until the end of copying for both the controller CC and the switchboard RPOS. When the copying process is through with the untransmitted information from using transmitters SLC0 and RSLC0 to spare transmitters SLC1 and RSLC1, the transmission of the copied information is started instantaneously to the remote side station, the controller CC0 and switchboard RPOS respectively since a data link L1 of the spare system holds synchronization.
