Title: Optical disk device
Inventor: YANAGIHARA SHUICHI
IPC: G11B19/12
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To obtain an optical disk device by which the time required to start the reproducing of the information on an optical disk is shortened without erasing recording contents. SOLUTION: A focus search is conducted prior to conducting a focus servo (S1 and S2). A first counter counts the number of pulses obtained based on focus error signals generated during the focus search. A second counter measures the time from the starting of the focus search until the generation of the pulses. A discrimination is made to determine the kind of an optical disk from the difference in the measured value of the first counter (S3). Then, the measured time of the second counter is compared with a threshold value and the kind of the disk is discriminated by the comparison (S6).

Title: Communication-band limiting method, communication-band reserving method and network node device
Inventor: SHOHATA YASURO
IPC: H04L47/21
Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To ensure transmission quality of a VC(virtual circuit) and further to omit transmission confirmation that minimizes a time that is needed to set the VC by making an average of cycles to be no less than the minimum value of cycle that an output a packet and also making the sums of thresholds not to exceed the number of packets that can be stored by a buffer. SOLUTION: When an NT (network terminating device) 104e receives a data packet and when the value held by a counting device of leaky packet means 10424a and 10424b which correspond to a terminal that generates a data packet is equal to or exceeds a threshold that is equal to the packet number which corresponds to burst time excess flow, the NT 104e discards the received data packet. Because the operation is applied for all the VPs (virtual path) to which the operation is set, each VP can no longer use a communication band that is more than a reserved communication band, and the discard of each VP packet in of does not occur.

Title: Manufacture of laminated plate

Filed: 1988-03-03
Abstract: PURPOSE:To avoid surface crack caused in processing of a deformed hole, by selecting a paper base material so that the bending distortion of a laminated plate is not more than a specific value. CONSTITUTION:Such paper base material is selected that can make the bending distortion of a molded laminated plate not more than 3.7%. If a linter paper, craft paper or the like containing alpha cellulose in 95% or more is singly used, the bending distortion may exceed 3.7% in some cases. Therefore, it is necessary to select the structure of the paper base material. Using resin is phenol resin, epoxy resin, unsaturated polyester resin or polyimide resin. When the resin is modified by a plasticizer etc., the modulus of elasticity declines and the bending distortion increases, or the bonding distortion varies depending on the case where a single resin is used or resins are mixed. Therefore, by utilizing these facts, the bending distortion can be adjusted by the resins.
