Title: Knocking detecting device for internal combustion engine
Inventor: KOIKE YUZURU
IPC: F02D41/22
Filed: 1989-02-09
Abstract: PURPOSE:To accurately detect whether or not knocking occurs or not by calculating a correcting value set corresponding to a transient state when the transient state is detected, and correcting a noise level calculated value with the calculated correcting value. CONSTITUTION:A knocking sensor 1 detects vibrations of the engine and a rotational frequency detecting means 2 detects the rotational frequency of the engine. Then a noise level calculating means 3 inputs the outputs of the sensor 1 and means 2 and uses a time constant set corresponding to the engine rotational frequency to fractionize the knocking sensor output, thereby finding a noise level. Then a knocking decision level calculating means 4 inputs the output of the means 3 to find a knocking decision level from the noise level and a knocking decision means 5 inputs and compares the outputs of the means 4 and sensor 1 with each other to decide whether or not the knocking occurs. Here, the means 3 inputs the output of a transient state detecting means 6 and calculates the correcting value set corresponding to the transient state when the transient state is detected to correct the noise level calculated value by using the calculated correcting value.

Filed: 1990-02-09
Abstract: PURPOSE:To prevent injury on respective sides and deterioration of the seal performance of seal parts of a fluid chamber due to generation of aluminum powder by forming the rotating direction side of the extreme end part of vane part of a rotor into a circular arc shape. CONSTITUTION:A rotor 14 is formed out of iron, the respective vane parts 14b are formed into a circular arc shape from the top part 14b1 of the extreme end part to the side part positions 14b2 in the right and left rotating directions and the section is formed into a wedge shape of long ellipse extending in the right and left rotating direction. Because the side positions 14b2 in the rotating direction of the extreme end part of the vane part 14b of the rotor 14 is formed into a circular arc shape without any corner part, even if the rotor 14 is inclined in front or rear against an inner shaft 12 or twisted to the right and left, the extreme end part does not interfere with the other side 13d of a working piston 13 or the one side 15b of an end cover 15. Consequently, there is no possibility that respective sides 13d, 15b are injured and the seal performance of seal parts against the outer case 11 and the inner shaft 12 is deteriorated due to aluminum powder generated by such injury.

Filed: 1983-02-24
Abstract: PURPOSE:To prevent a trouble due to breakdown of a semiconductor laser element and impression of reverse bias from happening by a method wherein a semiconductor laser element connected in series and an external resistor are connected to a Zener diode in parallel. CONSTITUTION:A semiconductor laser element 2 connected in series and an external resistor 1 are connected to a Zener diode 3 in parallel. Assuming that the element 2 is impressed with surge voltage to supply surge current e.g. around 100mA through the external resistor 1, both end voltage including the resistor 1 and the element 2 reaches around 5-6V to make the diode 3 break down supplying surge current to prevent the element 2 from being broken down. Besides when both ends including the element 2 and the resistor 1 are impressed with reverse bias voltage, the current due to this reverse bias voltage may be supplied mostly through the intermediary of the diode 3 owing to the normal directional characteristics of said diode 3.
