Title: Copy judgment method and reader
Inventor: SATOU HIRAYUKI
IPC: G06F21/14
Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To inhibit the use of CD-ROM which is illegally copied by judging the error rate of data which is read from CD-ROM. SOLUTION: Key code data which a bit read part 2 reads is errorcorrected by an error correction part 3 and is transferred to the error rate comparison part of a judgment part 4 by a key code data extraction part 7. The error rate comparison part checks the number of corrected key code data and the number of key code data which cannot be corrected among transferred key code data. The total number is divided by all the number of key code data so as to obtain the error rate Q. Since the error rate K is given to key code data in legal CD-ROM, the error rate Q is compared with the error rate K, When it becomes Q≈K, the CD-ROM is legal. When it is judged to be legal as the result of judgment, a bit read control part gives the indication of the reading of user data to the bit read part 2.

Title: Vertical synchronizing circuit
Inventor: KAWAHARA TSUKASA
IPC: H04N5/06
Filed: 1989-02-14
Abstract: PURPOSE:To easily make the frequency of a vertical synchronizing output coincident by switching the frequency division ratio of a frequency divider with respect to a vertical synchronizing input with a different frequency. CONSTITUTION:Plural frequency division outputs with a different frequency division ratio are set to a frequency divider 4, the frequency division output is switched by a switching circuit 7 to reset the frequency divider 4 and the switching circuit 7 is used to detect the amplitude of the vertical synchronizing input to switch the frequency division output in response to the quantity of the amplitude. Thus, the frequency division output having the same frequency as that of the oscillated output of a vertical oscillator is easily generated by the frequency divider 4. Moreover, malfunction at the changeover of the output in the switching circuit 7 is avoided. Thus, stable vertical synchronizing output is easily obtained with respect to the vertical synchronizing input with a different frequency.

Abstract: PURPOSE:To facilitate the detection of defects of switch transistors of respective picture elements by easily measuring an ON resistance value and OFF resistance value of transistors connected in series with external teminals. CONSTITUTION:A resistance value between a drain bus X1 and X2 is measured in a condition in which a selective voltage is imparted to a gate bus Y1 and non-selective voltages are imparted to others. At this time, MOS transistors MA22 and MB12 are turned on and the resistance value between the drain bus X1 and X2 is enough large as long as a short-circuited defect is not present thereon since other MOS transistor connected between the drain bus X1 and X2 is turned off. When the resistance value is smaller than the prescribed value, short-circuited defects are present on a MOS transistor MB22 or MA12 connected to MOS transistors MA22 and MB12. Thus, the other defect detecting method such as the shape recognization is facilitated, since the defective position is limitted.

Abstract: PURPOSE: To reduce the load being applied to watch wheel trains, prolong contact life and prevent noise production by defining the driving time of a sounding body with the capacity of a capacitor so that no influence is given to the operation of the sounding body even if the distance time between the unlocking wheel and the hour hand wheel is taken long.  
     CONSTITUTION: When the time having been set by an unlocking wheel 3 is reached, the protruding parts 10, 11 of an hour hand wheel 9 fit into the engaging holes 4, 5 of the unlocking wheel 3. Further when the hour hand wheel 9 turns, the protruding parts 10, 11 again ride on the plane of the unlocking wheel 3 while the tapered parts of the protruding parts 10, 11 slide on the tapered faces 6, 7 of the engaging holes 4, 5. In this case, while a traveling contact spring 15 is making contact to one fixed contact spring 16 before the protruding parts 10, 11 fit, a capacitor 22 is being charged by way of the fixed contact spring 16 and traveling contact spring 15. Hence, when the protruding parts 10, 11 plunge and the traveling contact spring 15 touches the other fixed contact spring 17, then a transistor 20 is biased by the discharge current of the capacitor 22 and a sounding body 19 is operated only during the discharge period of the capacitor 22.
