Inventor: TSUBURAYA YOSHITANE
IPC: G11B7/24094
Filed: 1989-12-29
Abstract: PURPOSE:To detect the life of the optical recording medium with high reliability by recording a program to evaluate the life of the recording medium in a part of the recording region or non-recording region. CONSTITUTION:The program to evaluate the life of the optical recording medium 1 by measuring any one of the recording characteristics, reproducing characteristics and tracking characteristics of the optical recording medium 1 and the focus characteristics of an optical head provided on a drive using the above-mentioned recording medium 1 is recorded on the recording medium 1 itself by using a part of the recording region 2 or non-recording region. Whether the life of the optical recording medium 1 is in a nearly running out state or not is, therefore, detected before the recording/reproducing operations of user information in a user region is executed. The need for storing the program necessary for detecting the life in the drive is eliminated. The load of the drive is decreased in this way and the life is detected with the high reliability.

Title: Controlling device for drive of motor
Inventor: NISHIBE TAIJI
IPC: B60J1/17
Filed: 1992-12-25
Abstract: PURPOSE:To prevent the continuation of the overloading state of a motor irrespective of the temperature of the motor, whether low or high in temperature. CONSTITUTION:A jammed-foreign matter detection/control circuit 66 performs foreign matter detection when a low-level signal is inputted from a comparator 86 and does not perform the detection when a high-level signal (inhibit signal) is inputted at a temperature equal to or lower than a prescribed temperature (-10 deg.C to -20 deg.C). The resisting force of door glass increases at the moving time due to the malfunction of a window regulator or hardness variation of weather strips. Thus the unnecessary operation of the circuit 66 is prevented by stopping the jammed-foreign matter detection of the circuit 66 at a low- temperature time, because the driving current of a motor 22 which increases due to the resisting force exceeds a comparing current at the same level as that at a normal-temperature time in the case the circuit 66 tries to perform the foreign matter detection with a comparing current when the resisting force increases.
