Title: Tracking controller
Inventor: YAMAZAKI MITSUO
IPC: G11B7/095
Filed: 1998-06-17
Abstract: PROBLEM TO BE SOLVED: To stably perform a tracking servo even if there are dust and scratch on an optical disk. SOLUTION: Relating to photo-detecting parts 11A, 11B information rows spaced at regular intervals in the radial direction of an optical disk 10 is irradiated with laser and the reflected light is detected. Tracking error signal generating parts 13, 16 obtain tracking error signals between the corresponding information rows and the irradiation positions of laser based on the detected light from the corresponding respective photo-detecting parts 11A, 11B. A tracking servo controller part 14 uses the two tracking error signals, and generates a servo control signal for controlling the photo-detecting part 11A so that the reflected light inputted to the photo-detecting part 11A becomes light reflected from the information row.

Title: Path search system
Inventor: ITO YOSHIHARU
IPC: H04L12/66
Filed: 1998-06-02
Abstract: PROBLEM TO BE SOLVED: To provide a path search system capable of efficiently searching a path in response to a degree of congestion of a transmission line in a communication network where each repeater successively decides data transfer paths by providing repeaters at boundaries adjustment networks. SOLUTION: In the case of transferring an IP packet from a terminal S1 in a network LAN a1 to a terminal of other network LAN a4, each of repeaters Rta1 to Rta3 that receives transfer data extracts an IP address of a data source and a data destination and decides routing based on the information in this path search system.  Each of the repeaters Rta1 to Rta3 monitors traffic of the transmission line and retrieves information registered in its own cache when a degree of congestion of the transmission line is high and omits the path search from an IP layer level when there are data having been transferred in the past under the same condition and uses directly path information (VP/VC) of a MAC layer level having been registered to transfer data, and executes the path search from the IP layer level when the transmission line is free and searches the path to a succeeding repeater one after another.

Abstract: PURPOSE:To produce a low-cost decorative body functioning as a decorative sheet with a rich sense of beauty, preventing a peeling accident, and having a rust proof effect and a waterproof effect by a method wherein a polymer cement mortar mixed with natural stone is applied to a base body, and a surface layer is removed after the mortar is half or completely cured so that the natural stone is exposed. CONSTITUTION:Granular natural stone 10 is kneaded with a polymer cement mortar in the amount of approximately 0.3 pts.wt. per 1 pts.wt. of the polymer cement mortar. A black pigment is further added in the amount of approximately 0.0002 pts.wt. and kneaded. The obtained material is a coating material 12. The coating material 12 is applied to a steel material 11 by a trowel, dried, and cured. After the coating material 12 is sufficiently dried and cured, the surface is smoothed by using a disk grinder, a belt sander, or the like. Furthermore, the surface is made glossy using sandpaper, a grinding wheel, or the like while being wet by water. Thus, a decorative sheet A is obtained. In addition, since the surface has a semigloss in this state, a coating material, such as a clear lacquer, is applied if a higher glossiness is required.

IPC: G01R1/04
Filed: 1994-06-29
Abstract: PURPOSE:To sustain the relative positional relationship substantially intact between the contact part of a probe and the pad of an LSI chip even if high temperature measurement is effected by applying an insulating coating at least to the part touching a probe on the surface of a carbon probe card ring for high temperature measurement. CONSTITUTION:The probe card 100 tar high temperature measurement is made of carbon and fixed to a substrate 200 wherein an insulating coating 400 is applied at least to the part of the surface touching a probe. The coefficient of linear expansion of silicon being employed in an LSI to be measured is 4.0X10<-6> and that of carbon is 4.2-4.9X10<-6>. Consequently, even if heated during high temperature measurement, thermal expansion of the card ring 100 is substantially identical to that of the LSI.
