Filed: 1981-04-22
Abstract: PURPOSE:To ensure a high-contrast display regardless of the brightness, by using a display plate with a high degree of brightness and using a light source when the brightness is low respectively after setting the light source at the back of the display plate. CONSTITUTION:For instance, when the brightness is high around a display meter at a service station, an output signal of ''bright'' detection is fed to an AND circuit 30 from a brightness detector 28. Thereafter, a hose 25 is lowered down for the supply of oil. Thus the output signal of a pulse oscillator 19 provided to a flowmeter 18 in the middle of an oil supply tube actuates a display plate via a counter circuit 20, a display driving circuit 22, etc. to display a figure of three digits. When the brightness becomes low around the display meter, an output signal of ''dark'' is led into an AND circuit 29 from the detector 28. At the same time, an FF circuit 31 feeds the output signal to a light source and a circuit of a motor 15. Then all light sources of the display meter 13 are turned on to display a figure of three digits through display parts 12, 12' and 12''. Thus a high-contrast display is possible regardless of the brightness.

Abstract: PURPOSE:To prevent any propagation of discharge pulsation as well as to promote a reduction in vibrations and noises by setting up each discharge port of discharge cavities partitioned off into two chambers, an interconnecting passage lying between these two cavities and a discharge pipe in a zigzag manner. CONSTITUTION:A discharge cavity is partitioned off into a first discharge cavity 10 where discharge port 6 opens, and a second discharge cavity 11 where a discharge pipe 1 opens with a partition plate 7, and capacity in the first discharge cavity 10 is made larger than that of the second discharge cavity 11. In this constitution, an interconnecting passage 8 interconnecting both these first and second discharge cavities 10 and 11 is installed in this partition plate 7, and the discharge port 6, this interconnecting passage 8 lying between both the first and second discharge cavities and the discharge pipe 1 are set up in the zigzag positions. With this constitution, an acoustic mode of the discharge cavity shifts to a high frequency side being small in discharge pulsation and thereby this discharge pulsation is reducible to some extent, so that muffler reducing sound volume at the low frequency area is increased. In addition, rigidity in an upper housing 2 is heightened and therefore vibration is reducible.
