Abstract: PURPOSE:To prevent knocking from being generated, by opening an air introducing valve, provided in the opening part of an air introducing passage opened to a combustion chamber, simultaneously with the opening action of an exhaust valve so as to well perform scavenging of combustion gas over the whole range of an exhaust stroke. CONSTITUTION:A four-cycle engine opens to its combustion chamber 10 an air introducing passage 40 to enable delivery air of an air pump 42 to be introduced. The engine provides an air introducing valve 50, which synchronously opens with a crankshaft 31 in an exhaust stroke, in an opening part 41 of the air introducing passage 40 to the combustion chamber 10, and the air introducing valve 50 is opened and closed by the action of a cam 51 on a cam shaft 20 through a push rod 53, rocker arm 54, etc. While the air introducing passage 40 interposes a flow control valve 60 which are controlled so as to decrease an introducing amount of air to the combustion chamber in a low load range. Said flow control valve 60 is constituted such that it throttles the introducing amount of air by displacing a valve unit 61, integrally formed with a diaphragm 63, to the side of a valve seat 62 against a spring 66 in accordance with an increase of intake pipe negative pressure introduced to a negative pressure chamber 64.

Filed: 1978-11-06
Abstract: PURPOSE:To secure an automatic record of high quality free from the saturation distortion of the magnetic tape by performing the level setting with the digital control given to the signal attenuator groups distributed at the signal transmission line. CONSTITUTION:When the level setting mode is secured with push of switch 8, digital counter 5 delivers the count value equivalent to sample value 7, 10, 12 and 13 of every fixed period of level 6 where input signal 1 exceeds reference level 4. Thus the total attenuation quantity is controlled for resistance attanuator group 3 via latch circuit 14 and comparator 15. In case the recording level is set for the tape deck, output terminal 2 is connected to the record amplifier of the tape deck, and the record current is supplied to the magnetic head. At the same time, group 3 is set with switch 8 set so that the peak of the input signal may be recorded with the maximum recording level of the magnetic tape. As a result, an automatic high- quality recording is possible without any saturation distortion of the magnetic tape for the input signal.
