Title: Device for detecting weak ignition of spark plug
Inventor: SATO HIROSHI
IPC: F02P17/00
Filed: 1985-01-22
Abstract: PURPOSE:To make it possible to precisely detect weak ignition of a spark plug, by noticing that the amplitude of oscillation which is determined in accordance with the secondary impedance and floating capacity of an ignition coil, decreases when smolder and dirt exist on the spark plug, and by utilizing this fact to detect weak ignition. CONSTITUTION:With respect to a discharge voltage waveform detected by a voltage detecting section 15, a band filter circuit 16 extracts the oscillating component corresponding to the oscillating frequency upon normal operation. Further, the thus extracted oscillating component is subjected to a half-wave rectification and is smoothed, and is then led to a comparator circuit 18. Further, a reference signal SR from a reference signal generating circuit 17 is compared with a signal SA from the band pass filter circuit 16, and when the ignition is normal, a detection signal SD may be obtained. At this stage, if the detection signal may not be obtained in a predetermined time from the ignition timing, it is determined that any smoke or dirt is generated on a spark plug 9. With this arrangement, it is possible to precisely determine the presence of inferior ignition irrespective of the values of pressure in a combustion chamber and vortex flow in the spark gap.

Title: Ignition time controlling apparatus of engine quipped with air governor
Inventor: SHIMIZU ISAO
IPC: F02P5/06
Filed: 1978-01-27
Abstract: PURPOSE:To obtain high power effectively and reduce noise by delaying the ignition time in the air cylinder with the increase of revolution speed, in the revolution speed range in the decrease of power due to the operation of an air governor. CONSTITUTION:When an engine is at a stop, the pin 3a of a flyweight 3 is positioned at the end position closest to the revolution center of the curved long hole 5a on a timing lever 5 by the action of a spring 4. When the engine begins to revolve and gradually increases the revolution speed, a centrifugal force operates onto the flyweight 3, and the flyweight tends to extend outside against the tension of the spring 4. As the pin 3a of the flyweight 3 extends outside along the long hole 5a too, ignition advance alpha increases and ignition time advances. Further, when the engine revolution speed increases, an air governor operates, and engine power drops sharply.

Filed: 1982-01-25
Abstract: PURPOSE:To make a flowmeter suitable for mass production by a constitution wherein a diaphragm formed of non-magnetic metal material is provided along the plane of an opening of a casing wherein a pair of rotors are housed, and a second casing fitted with a magnetism-responding element detecting the magnetic action of magnets provided in the rotors is fixed monolithically to the diaphragm. CONSTITUTION:A fluid to be measured enters a measuring chamber 5 from a fluid inlet pipe 23 and, rotating a pair of rotors 1, is discharged from a fluid outlet pipe 25 on the other side. The rotation of the rotors 1 is accurately detected magnetoelectrically, since magnets 6 buried in the rotors 1 make a magnetism-responding element 20 operate through the intermediary of a diaphragm 16. Then a detecting-counting mechanism 19 operates to count the speed of rotation of the rotors 1, and thus a value of flow rate can be indicated by an indicator. A casing which forms the measuring chamber requiring precision is formed to be compact and rigid of a light alloy by cold forging, while a casing provided with the detecting-counting mechanism can be prepared simply by molding or the like, since it requires only moderate precision.

Filed: 1997-01-23
Abstract: PROBLEM TO BE SOLVED: To realize minute flow rate condition, in which noise due to the flow of refrigerant is not generated, and secure oil return to a compressor and prevent hunting sound by a method wherein an annular refrigerant passage, surrounding a valve disc, is formed when the valve disc is positioned at a condition, minimizing the flow rate of the refrigerant. SOLUTION: A valve disc 21 is brought into a condition that the same is entered into a throttling hole 15 under a condition that the flow rate of high- pressure refrigerant, sent into an evaporator 1, is minimized. An annular slight gap is produced between the inner peripheral surface of the throttling hole 15 and the outer surface of the valve disc 21 whereby the annular gap becomes the passage of refrigerant and the refrigerant flows as shown by an arrow sign, shown by broken lines, in a diagram. Accordingly, hunting sound will not be generated even under the minimum flow rate condition and oil, mixed into the refrigerant, is returned into a compressor 2 whereby seizure and the like of the compressor 2 will not be generated. The passing sound of the refrigerant will not be generated substantially whereby the same will not become the source of noise.
