Title: Ignition timing controller for internal combustion engine
Inventor: NAKAHARA YOSHIO
IPC: F02P5/152
Filed: 1980-06-16
Abstract: PURPOSE: To prevent preignition in an engine, by providing in an ignition timing controller a detecting circuit that produces output in accordance with the generation timing of preignition in a spark plug and a spark discharge timing adjusting device that controls the discharge timing in accordance with output of the detecting the discharge timing in accordance with output of the detecting circuit.  
     CONSTITUTION: Preignition is detected by cancelling spark discharge voltage in a circuit 2 from a signal detected in an ion current detecting circuit 1. Decision of this signal is performed in a comparator circuit 3 for whether it is at least the prescribed value or not. At occurrence of the preignition, a pulse is generated in a pulse width conversion circuit 4 to turn on a transistor T during this generation time, then the ignition angle becomes a retard angle. In this way, troubles in a spark plug and engine due to the preignition can be prevented.

Title: Device and method for correcting error
Inventor: KOIKE HIDEYUKI
IPC: H03M13/00
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To perform TBC processing by using less external RAMs and with simple memory control in an error correction device. SOLUTION: The reproduced data supplied to an error correction decoder 9 are written in a FIFO 43 in sync block based on the RF clock of the reproduced data. The read-out from the FIFO 43 is performed based on a system clock with a frequency sufficiently higher than the RF clock. The data from the FIFO 43 are removed beforehand in jitters to be written in a synchronizing SDRAM 30. When the data by one track much are stored, the read-out is performed. The control of the write-in/read-out for the SDRAM 30 is performed by a system clock, and since the write-in/read-out for the SDRAM 30 is performed in a time sufficiently shorter than a reproducing time of one sync block, plural write-in/read-out processing are performed by time division, and the SDRAM 30 is shared with plural data series.
