Title: Optical recording medium
Inventor: YAMAMOTO MASAKUNI
IPC: G11B7/24091
Filed: 1988-12-21
Abstract: PURPOSE:To simplify the production process of a master disk for the recording medium and to reduce bad influence of tracking error signals by partitioning the area of the optical recording medium into servo areas and data areas and providing preformat pits in the servo area in a manner that the pit is positioned at the center of the track width with its longitudinal direction in the track direction. CONSTITUTION:The medium has several blocks 22 consisting of the data area 24 into or from which informations are optically written or read out, and the servo area 23 which separated from this data area 24 and produces tracking error signals. The servo area 23 has at least one pit in the center position of its width with the longitudinal direction of the pit along the track direction. By this method, the master disk can be easily produced and bad influence of a tracking error signal due to a defect comparable to the pit size can be reduced.

Title: Motor control device for electrically-driven power steering
Inventor: KURIYAMA SHIGERU
IPC: H02P7/29
Filed: 1988-12-21
Abstract: PURPOSE:To suppress electromagnetic wave noise by providing a function to change conduction control of a DC motor from usual chopper control to continuous conduction control in specific conditions. CONSTITUTION:A DC motor 6 is controlled by continuous conduction control in specific conditions determined by the temperatures of the field effect transistors (FET's) 41-44 of a chopper circuit 5 and other factors. Therefore, a temperature sensor 12 is installed to monitor the temperatures of the FETs 41-44 of the chopper circuit 5. Temperature data are stored as a signal AD3 into a microcomputer 9 and, as a result of it, continuous conduction control is performed instead of chopper control only when the temperatures are lower than specified. Thereby electromagnetic noise caused by chopper control can be suppressed.

Title: Bit error rate measuring circuit
Inventor: ODA SHINICHI
IPC: H03M13/00
Filed: 1988-12-21
Abstract: PURPOSE:To shorten measuring time by counting the number of clocks while a requested number of bit errors is counted, and computing a bit error rate at an arithmetic circuit. CONSTITUTION:A bit error counter circuit 1 outputs the number of bit errors counted until a time when the number of bit error pulse signals to be counted arrives at a prescribed value to the arithmetic circuit 4, and simultaneously, outputs a stop signal to an AND circuit 2. The AND circuit 2 outputs the clock as it is while counting, and prohibits the output of the clock at a time when the stop signal is inputted. A clock counter circuit 3 counts the number of clocks outputted from the AND circuit 2, and outputs the number of clocks counted until then to the arithmetic circuit 4. The arithmetic circuit 4 performs division setting the number of bit errors as a numerator and the number of clocks as a denominator, and outputs the bit error rate. In such a manner, it is possible to reduce the counting of the number of clocks required for the measurement of the bit error rate with requested accuracy, and to shorten the measuring time.
