Abstract: PURPOSE:To give a microvibration to lubricating oil housed in an oil pan, thereby making bubbles being contained in this lubricating oil go up quickly and eliminating them efficiently, and prevent a lubrication shortage or the like from occurring by installing an ultrasonic generator additionally in the oil pan. CONSTITUTION:In an engine, an oil pan 2 is connected to the lower part of a crankcase 1, and lubricating oil 3 is housed in this oil pan 2. During engine driving, the lubricating oil 3 is sucked up from a straight 5 installed in a suction port of an oil pump interlocking with a crankshaft 4, and fed to each sliding part of the engine. In this constitution aforesaid, an ultrasonic generator 6 is additionally installed in a lower end of the oil pan 2. Then, this ultrasonic generator 6 is connected to a battery 8 via a switch 7 interlocking with an engine switch, thereby generating a microvibration during the engine driving. With this operation, bubbles being contained in the lubricating oil 3 are quickly raised up by the microvibration, and efficiently eliminated.

Abstract: PURPOSE:To suppress the Zn diffusion from a sacriticial material to a core material and to prevent the degradation in pitting corrosion resistance by using an Al alloy contg. Zn, Mg, Zr, Fe, and Si for a sacrificial material and using an Al alloy nobler in the potential than the core material for the core material. CONSTITUTION:An Al alloy brazing material is clad on the outer side (atm. side) of the core material consisting of the Al alloy and the sacrificial material of the Al alloy is clad on the inner side (refrigerant side) to form the brazing sheet for the refrigerant passage of the heat exchanger made of the Al. The alloy consisting of 0.5 to 5.0wt.% Zn, 0.05 to 1.5% Mg, 0.03 to 0.3% Zr, <=0.4% Fe, <=0.6% Si, and the balance Al and unavoidable impurities is used for this sacrificial material and the Ar alloy nobler in the potential than the sacrificial material is used for the core material.

Title: Spectrophotometer
Inventor: AKIYAMA OSAMU
IPC: G01J3/02
Filed: 1986-10-31
Abstract: PURPOSE:To eliminate problems caused by the hysteresis of sensitivity characteristics of a photodetector at the time of photodetector switching by making light incident on the photodetector which is not used for measurement in measuring operation all the time. CONSTITUTION:A half-mirror Mh is used as a means which switches the 1st and the 2nd photodetectors P1 and P2 of a photometer. The half-mirror Mh is fixed slantingly by 45 deg. to the incident light, which is split to the 1st and the 2nd photodetectors P1 and P2 all the time. In this constitution, the light is incident on the photodetectors P1 and P2, specially, the photoelectron multiplier tube P1 throughout the measurement, so even when an in-use detector is switched from P2 to P1 on the side of a measuring circuit, the photodetection state is unchanged before and after the switching and there is no temporary variation of a 100% transmissivity line due to the hysteresis of the sensitivity characteristics. Consequently, an increase in measured value and drift before and after the photodetector switching are compressed and result with good reproducibility are obtained by the repetitive measurement.
