Title: Information processing method for recording disk
Inventor: NISHIDA JUNICHI
IPC: G11B19/10
Filed: 1992-05-08
Abstract: PURPOSE:To make the start-up rapid by reading and registering information of a table of contents(TOC) of each recording disk, a volume disk printer information and information VD stored in the disk whenever a power source is inputted, comparing the TOC information at the time of inputting the power source again between the previous time and this time and utilizing the VD information as it is upon coincidence. CONSTITUTION:When plural recording disks coexist in a large number, the probability of existence of disks having the exactly same TOC information is extremely low, and if so, there is almost no probability that all the disks in a magazine 16 have the same TOC information before and after their exchanges, so that the TOC information is used as a deciding factor of disk exchanges in the magazine 16, and the identity of the disk is decided by confirming the identity between its new and old TOC information. Consequently, whether disks exist or not in the magazine 16 is detected in a multi-CD player 7, and when they exist, the TOC information of each disk is fetched, and when it is identical to the previous one, no disk changes are regarded so as to proceed further processing.

Title: Tester for wooden pole deterioration
Inventor: TAKASHIMA IZUMI
IPC: G01N33/46
Filed: 1981-07-24
Abstract: PURPOSE:To discriminate deterioration with high accuracy, by detecting the displacement velocity of a drill and discriminating disappearance of annual ring patterns at the velocity signal. CONSTITUTION:An output signal of an amplifier circuit 6 of a displacement signal of a drill is compared with a reference level L at a comparator 7 to obtain a pulse and the periods Ti, Ti+1, Ti+2- are detected at a period detection circuit 8. That is, the maximum value of the period is predetermined and the period Ti which becomes greater than the value is detected or the ratio Ti+1/Ti is set to detect that the measured value is greater than the set value of the Ti+1/Ti. Thus, when a signal pattern in response to annual rings is disappeared, a deterioration detection signal (d) is outputted for display or recording. Thus, the dicrimination with high accuracy can be performed.
