Title: Carburettor opening regulator of car engine
Inventor: TAKAHASHI KIMIO
IPC: B60W10/10
Filed: 1981-04-15
Abstract: PURPOSE:To save fuel and so on in an arrangement, in which a multi-step geared speed changer is combined with an engine, by putting the operating piece for change of speed in linkage with the throttle valve of carburettor, regulating the opening of throttle valve while the low speed gear is being selected, and thereby making it impossible to set the engine in rapid acceleration. CONSTITUTION:A speed-change operating piece 1 is turned by swinging the speed change lever by certain degrees of angle in the sequence to perform change-over of a multi-step gear. Here, a cam piece 2 is fixed to one side in matching with the speed-change meshing position of the speed-change operating piece 1. A limiter lever 4 fitted on the shaft at the casing 3 with one end set in normal contact with the cam piece 2 by pressing with a spring 5. One end of a limiter wire 6 is coupled with the fore end of the limiter lever 4 while the other is connected to the midway of the wire 10 for operating the throttle valve 8 of carburettor 7 with a connecting piece 11 interposed. Accordingly, full opening of the throttle valve 8 is made impossible when the speed-change operating  piece 1 selects the low speed meshing, by allowing the operating wire 10 to contact the connecting piece 11 by means of depression of the limiter lever 4 with  cam piece 2 and consequent downward pulling of the limiter wire 6.

Title: Burner throat
Inventor: GOUUKON SHIGERU
IPC: F23C99/00
Filed: 1978-05-15
Abstract: PURPOSE: To reduce nitrogen oxides without increasing soot in the exhaust gas by shaping the opening of a burner throat a polygon.  
     CONSTITUTION: Throat opening 5 of this burner throat 5 is made a poligon. Consequently, fuel F ejected from burner throat 5 is made a poligon. Consequently, fuel F ejected from tip hole 7 of burner tip 6 fitted at the end of burner 1 is mixed with air A ejected via throat opening 5 enclosed by air resistor 2 and throat 4. At the time of combustion, a part of the air is made to escape from a corner of throat opening 5, and thereby many eddy currents are produced, and air and fuel are mixed univenly. As a result, by slowing down the combustion speed, high-temperature combustion, which tends to produce nitrogen oxides, is avoided, and combustion at relatively low temperature is made possible.

Abstract: PROBLEM TO BE SOLVED: To diagnose the part or the like of an abnormality cause by a method where in generated Lissajous waveform figures based on a vibration waveform signal are compared with every reference Lissajous waveform figure which is set already. SOLUTION: A vibration which is generated in the mounting position of a shaft due to the rotating drive of a motor is detected by both vibration detecting elements 1, 2. Vibration waveform signals of the detected vibration are outputted sequentially to a vibration detecting means 4. The signals are inputted to a Lissajous waveform- figure generation means 5, and Lissajous waveform figures are generated on the basis of both vibration waveform signals. On the other hand, a reference Lissajous waveform- figure generation means 6 previously sets and stores reference Lissajous waveform figures in a normal state and a plurality of reference Lissajous waveform figures which are assumed on the basis of every abnormality cause. Then, an abnormality- cause judgment means 7 compares the generated Lissajous waveform signals with every reference Lissajous waveform figure. When the generated Lissajous waveform figures are similar to any of reference Lissajous waveform figures which are not normal, it is judged that an abnormality is due to a cause according to the similar reference Lissajous waveform figures.

Abstract: PURPOSE:To obtain the titled crucible capable of growing a single crystal having high resistivity repeatedly, efficiently, and stably when a compd. semiconductor is grown by coating crystalline AlN having a low content of Si on the inner surface of the crucible. CONSTITUTION:The crystalline AlN contg. <=10ppm Si is coated on the inner surface of the crucible. The crystalline AlN is preferably obtained by chemical vapor deposition.
