Title: Kicker control system of video disk player
Inventor: FURUICHI TOKIISA
IPC: G11B21/02
Filed: 1983-07-30
Abstract: PURPOSE:To attain the stable control of a kicker with no runaway, etc. of a stylus on a disk even in case the stylus has failed in jumping a groove by controlling an electric pulse applied to a kick means with reference to the impulse peak value stored in a memory. CONSTITUTION:The pulse width corresponding to the maximum impulse is referred to for comparison carried out through a comparator 13 between said pulse width and the kick pulse width fed from a control circuit 7. In this case, both the impulse and the number of jumping grooves of a memory circuit 16 increase monotonously with said maximum impulse and the number of jumping grooves is decreased with the value larger than the maximum impulse. When the kick pulse width is larger than the pulse width corresponding to the maximum impulse, a switch 14 is changed over via the comparator 13. Thus no kick pulse is applied to a kick means. As a result, the width of an electric kick pulse has no one- sided increase even in case a stylus has failed in jumping a groove. This prevents a runaway, etc. of the stylus on a disk and ensures the stable control of a kicker.

Title: Trigger circuit for static induction thyristor
Inventor: KOMODA TAKUYA
IPC: H03K17/73
Filed: 1986-06-14
Abstract: PURPOSE:To suppress a steep peak current without increasing the delay time at turn-off by connecting a connecting point of two complementary switching elements connected in series to a gate of a static induction thristor via a resistor and applying a control pulse signal to a control terminal of both the switching elements. CONSTITUTION:A resistance of a resistor R is set to a value minimizing the gate trigger energy of a static induction thyristor Ts. Thus, the turnoff energy has a minimum value at a vresistance Ra, the turn-off delay time is increased gradually with a resistance below Ra and increased rapidly with a resistance of Ra or over. In selecting the resistanceof the resistor as nearly Ra, the turn-off energy is set near a minimum value without increasing remarkably the turn-off delay time. The value Ra is nearly 10ohm-1kohm, although the value has a variance depending on the type of the static induction thyristor.
