Abstract: PURPOSE:To suppress an oscillation of the primary current and to prevent an error ignition by providing a base current delay feeding circuit to increase gradually a base current fed to a bipolar power transistor to turn on and off the primary current of an ignition coil, when the signal voltage for feeding said base current is started. CONSTITUTION:A control signal is generated by a control unit 12 to input an ignition timing signal from an ignition timing sensor 11, and fed to a power switching circuit 13. And by turning on a bipolar power transistor Q1 in the circuit 13 at a high speed, a high voltage is generated in the primary winding 22 of an ignition coil 20, and a discharge spark is generated in the discharge gap of an ignition plug 40. In such an injection system, a base current delay feeding circuit 50 is assembled in the power switching circuit 13. By this base current delay feeding circuit 50, the base current flowing in the transistor Q1 is increased gradually after the signal voltage to feed the base current to the transistor Q1 is started.

Title: Mechanism for detecting solution level in high pressure regenerator
Inventor: TAITOU KAZUMA
IPC: G01F23/24
Filed: 1999-05-17
Abstract: PROBLEM TO BE SOLVED: To obtain a mechanism for detecting the solution level in a high pressure regenerator in which abnormal detection of the solution level is not determined when it is not required but determined only when it is required. SOLUTION: A solution level detector 110 communicates with a high pressure regenerator and solution Y intrudes therefrom into the detector 110. Solution level can be detected by judging conducting/nonconducting state between a common electrode rod 112a and detection electrode rods 112b-112e. A decision is made that the solution level is abnormal based on the detection electrode rods when the detection electrode rods detecting a relatively high solution level are in the conducting state but the detection electrode rods detecting a relatively low solution level are in the nonconducting state and the solution temperature detected by a temperature sensor 150 is equal to or higher than a set level.
