Title: Ion current detector
Inventor: IKEUCHI MASAYUKI
IPC: F02P17/00
Filed: 1990-11-09
Abstract: PURPOSE:To obtain excellent detectability by detecting an ion current which is caused by positive-polarity bias voltage given from a bias means and ions created in the combustion of mixture. CONSTITUTION:A power source 10 as a bias means applies positive-polarity bias voltage to a spark plug 3. At a spark timing for an internal combustion engine, discharge occurs between the electrodes of a spark plug 3 to ignite mixture in the internal combustion engine, when the combustion of mixture involves electrolytic dissociation to create ions. With the movement of electrons due to positive-polarity bias from a power source 10, an ion current flows in a passage shown in an arrow mark, but electrons have greatly smaller mass and faster moving speed than positive ions so that a great amount of ion current is obtained. Voltage developed in an output terminal 12 by the ion current can be detected to identify the combustion of mixture. It is thus possible to obtain excellent detectability.

Title: Focusing servo device
Inventor: YOKOTA HACHIRO
IPC: G11B7/085
Filed: 1989-11-24
Abstract: PURPOSE:To speed up the reacquisition of a focusing servo and to obtain a desired search waveform by limiting the variation range of the search signal and generating a digital signal corresponding to the signal. CONSTITUTION:The staircase wave voltage (V) generated by a focusing search signal generating circuit 11 is supplied to a focusing servo driver 7.
