Title: Ignition device for internal combustion engine
Inventor: KASHIMURA YUUICHI
IPC: F02P5/153
Filed: 1980-02-22
Abstract: PURPOSE:To prevent an engine against abnormal knocking even if the output of a sensor is intercepted by giving an angle of delay to the ignition timing not to give knocking when a pick-up coil in a knock sensor is disconnected. CONSTITUTION:A knock-controlling full transistor circuit on the basis of the output Vout of a knock-controlling circuit is composed of a phase-controlling circuit PC, a full transistor IC FT, a power transistor PT, an ignition coil IGC, and so on. A  pick-up signal is obtained from a pick-up coil PU. Meanwhile, on the basis of a  knock signal, a knock-pulse generator circuit outputs a step pulse. On the basis of  this output, a capacitor C101 shows a charge-discharge characteristic as illustrated.  These angles theta0 and theta1 for discharging are used for ignition angles of delay. A time  DELTAt corresponding to the ignition angle of delay theta1 is used for an ignition time of  delay for the ignition of an ignition coil IGC.

Title: Air-fuel ratio control method for internal combustion engine
Inventor: AKIYAMA EITETSU
IPC: F02D45/00
Filed: 1989-01-31
Abstract: PURPOSE:To compensate an air-fuel ratio conformed to exhaust gas temperature without installing any special temperature sensor by detecting a resistance value of a heater heating an exhaust density detecting element, and compensating the air-fuel ratio of mixture according to this resistance value. CONSTITUTION:An exhaust density sensor consisting of a detecting element 4a detecting the extent of exhaust density and a heater 4b heating this element is exposed to exhaust gas out of an internal combustion engine, while temperature in the heater itself, rising in exhaust gas temperature, also goes up, and a resistance value of the heater 4b is increased. A control circuit 1 finds the resistance value of the heater 4b, namely, exhaust gas density from each signal out of a heater voltage detector 11 and a heater current detector 12, performing the air-fuel ratio control conformed to the exhaust gas temperature. Thus an air-fuel ratio conformed to the exhaust gas temperature can be controlled without using any special temperature sensor.

Abstract: PROBLEM TO BE SOLVED: To make it possible to prevent a board from deforming by leaving bubbles behind in a material layer by a method wherein a deaerated material is dewatered through sucking by means of suction boxes so as to further flatten the nearly dewatered material with a flattening roller. SOLUTION: During the conveyance of each suction box 41 from the upstream side to the downstream side of the nearly horizontal running region 11a of a filter cloth 11, the greater part of the water content in a material layer 14 is sucked out by means of the suction boxes 14 and a suckingly dewatering means 55 so as to bring the material layer into a nearly dewaterd state. The dewatered material layer 14 is next abutted against a flattening roll 64 so as to pressurize the surface of the layer through the relative sliding contact with the outer peripheral surface part of the flattening roll 64 together with the rotation of the flattening roll 64. The surface of the material layer 14 is made through the pressurization flatter. Further, the suction of the water content in the material layer 14 through the suction boxes 41 is brought to an end just before or after this flattening roll so as to simply convey the material layer 14 passed through the flattening roll 64 with no suckingly dewatering.
