Title: Measuring method of pulser timing
Inventor: KIUCHI HITOSHI
IPC: G01R29/02
Filed: 1990-09-11
Abstract: PURPOSE:To measure precisely a phase difference between signals of one or a plurality of kinds of frequencies shifted in phase by 90 degrees and a signal sent from a pulser and subjected to detection, and also the amplitudes thereof, and to enable reproduction of an original waveform by preparing those signals and by subjecting them and the signal from the pulser to correlation and integration processings. CONSTITUTION:A signal received by an antenna 1 is subjected to band limitation 2 and detection 3. One or a plurality of kinds of frequencies being integral multiples of a frequency of 1/(period of a pulser) in consideration of a Doppler component are prepared simultaneously by a synthesizer 4 and frequency dividers 5. Two signals of sin and cos components 6 shifted in phase by 90 degrees are formed of those frequencies and these components and a signal sent from the pulser and subjected to detection 3 are subjected to correlation 7 and integration processings 8. According to this method, it is unnecessary to attain synchronization in the phase with the pulser signal and both amplitude information and phase information can be measured precisely. Besides, a pulser waveform can be reproduced by synthesizing the phases up to N times of a fundamental frequency again.

Title: Cd-rom copy preventing method
Inventor: TSUCHIYA YASUSHI
IPC: G11B20/00
Filed: 1990-09-10
Abstract: PURPOSE:To prevent the copy of a CD-ROM from being prepared by stopping the execution of a program by judging the copy of the CD-ROM when a prescribed data is not written in a sector not to be referred to from a directory. CONSTITUTION:The sector not to be referred to from the directory is provided on the CD-ROM, and any intensive data to be identified from the other data is written in the sector. On the other hand, it is programmed to refer to the sector when preparing a program to be stored in the CD-ROM. Further, when the data (intensive data) to be written in the relevant sector does not exist when the sector is referred to, the execution of the program is stopped by judging that the accessed CD-ROM is copied. Then, when the data to be originally written in the sector does not exist, the execution of the program is stopped. Thus, the copied CD-ROM is made ineffective, and the copy of the CD-ROM is prevented from being prepared.

Title: Magnetic bubble memory device
Inventor: OBATA SHOICHI
IPC: G11C11/14
Filed: 1986-10-09
Abstract: PURPOSE:To shorten access time by providing a page seek means so that a program for initial program load (IPL), which is initially read when a power source is turned on, can be read instantaneously after the power source is turned on. CONSTITUTION:The program for IPL previously stores a page address about a memory area 31 in an area 32. If the power source is turned on in time T6, a host processor 1 starts its own processing, and simultaneously reads out a defective loop. Meanwhile a control system 2 reads out the area 32 regardless of the host processor 1, and obtains a desired page address. Then the control system 2 instructs the page seek means 21 to search the page where the program for IPL is stored. When the host processor 1 terminates the initial processing in time T7 and issues a command to read the program for IPL, the program is read instantaneously in time T8. Thus the rise of the device is completed in a short time.
