Title: Lean limit detecting method utilizing ion current
Inventor: ASANO MORIHITO
IPC: F02D45/00
Filed: 1992-07-21
Abstract: PURPOSE:To easily control the air/fuel ratio in a lean burning area by measuring the characteristics of an ion current flowing to a cylinder immediately after ignition and detecting the lean limit based on the measured characteristics. CONSTITUTION:When a bias voltage is applied across a spark plug 18 from a bias power source immediately after ignition, the ion current suddenly flows and again increases after once decreasing before reaching a top dead center when the combustion is normal. Then the ion current reaches the maximum value near a crank angle at which the combustion pressure becomes the highest. When the combustion is unstable, on the contrary, the ion current value does not increase as a whole as compared with the normal combustion due to slow combustion during the second half of combustion. By measuring the ion current having such characteristics at prescribed time intervals, lean limit is detected based on the duration of a state where the ion current exceeds a preset burning state detecting level.

Title: Camera with flashing unit charging control circuit
Inventor: AIHARA YOSHIHIKO
IPC: G03B15/05
Filed: 1988-08-03
Abstract: PURPOSE:To promptly perform photographing without losing a shutter change by charging a stroboscope after photographing with a strobe light is performed and additionally charging the stroboscope for a definite period even when a voltage reaches a charge completion voltage. CONSTITUTION:Just after photographing with a strobe light is performed, charging is performed until the voltage charged in the stroboscope reaches a minimum voltage necessary for the light-emission as the preparation for next phototographing operation. Charging is continuously performed for the definite period, and then charging the stroboscope is stopped. That is, even if detecting means R3 and R4 detect that the voltage charged in the stroboscope becomes over a definite voltage which means the charge completion, charging is not stopped and a timer is continuously operated. Then charging is stopped after the charging operation for two seconds, and the preparation for the next photographing operation with a strobe light is completed. Thus, even when a charged voltage is gradually lowered due to a leakage before the next photographing operation, it is enhanced to a level for photographing with a strobe light regardless of a releasing time lag.
