Title: Reference level correction circuit for document reader
Inventor: KOMATA KYOICHI
IPC: H04N1/407
Filed: 1990-05-29
Abstract: PURPOSE:To improve a read rate by employing two constant current circuits and a capacitor so as to keep a reference level almost constant at all times independently of a temperature change. CONSTITUTION:A reference level signal outputted when a reference level luminous quantity generating means gives a luminous quantity equivalent to a reference black level or a reference white level to a prescribed position of a line type photoelectric conversion sensor 136 is amplified by an amplifier 200 and inputted to a detector 202. The detector 202 detects a reference level signal for each line and a comparator 204 compares the detected reference level with a setting level. Then the reference white level by feedback control due to increase/decrease in the terminal voltage for each line attended with charge/ discharge is almost kept constant. Since a feedback capacitor 212 is charged/ discharged by using constant current circuits 208,210 not susceptible to the effect of external disturbance, the reference level is easily made constant independently of a temperature change in the circuit.

Title: Glow plug
Inventor: SONODA KEISUKE
IPC: F23Q7/00
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To enhance convenience while saving power by arranging two heating elements of a glow plug disposed contiguously to a combustion chamber along gas flow thereby enhancing ignitability. SOLUTION: Two ceramic heating elements 3a, 3b are arranged on the housing 1 of a glow plug through a sleeve 2 in the direction of fuel and air flow. A heating coil 4 connected in series with a power supply 1 forms a 12 V glow plug which can deal with 24 V track bus. When a voltage is applied between positive and negative electrodes 6a, 6b connected with the heater coils 4 of the heating elements 3a, 3b through lead wires 5a, 5b, the heater coil 4 generates heat to red heat a part of two heating elements 3a, 3b thus providing an ignition point. Since the heating elements, 3b are arranged while being spaced apart along the direction of fuel and air flow, a tail flow is induced around the heating element on the downstream side and since the red heat part is located therein, fuel retaining performance is enhanced around the red heat part thus enhancing ignitability.
