Abstract: PURPOSE: To enhance lubricating and cooling performance of oil and blow-by performance by forming an oil guide passage inside of a chain case by two main ribs, and setting a height of ribs positioned in the oil guide passage between the two main ribs smaller than a height of the main ribs. CONSTITUTION: In a chain case 38 which is arranged on the surface side of an internal combustion engine and surrounds a motive power transmitting chain, two main ribs 40-1 and 40-2 are formed on its inside, and an oil guide passage 42 is formed to collect oil scattered in the chain case 38 by these. This oil guide passage 42 is arranged so as to point to a crankshaft, and a height of horizontal directional ribs 44-1 to 44-3 positioned in this oil guide passage 42 is formed lower than a height of the main ribs 40-1 and 40-2. Therefore, oil scattered in the chain case 38 is reliably and easily collected by the oil guide passage 42, and aeration is reduced, and lubricating performance is improved.

Title: Method for measuring freezing rate
Inventor: AIZAWA KAZUO
IPC: F25C1/08
Filed: 1987-02-10
Abstract: PURPOSE:To measure the electrical conductivity of an aq. soln. of an electrolyte by incorporating the electrolyte into water and to make continuous measurement of the freezing rate thereof from the relations among the measured value, the predetermined kind and concn. of the electrolyte and the freezing rate. CONSTITUTION:A small amt. of the electrolyte is preliminarily dissolved in the water in an ice regenerating tank 1. The liquid in the tank 1 is then fed by a liquid sampling pipe 8 having plural pieces of take-out ports to a pot 10 where the electrical conductivity is measured by an electrical conductivity meter 5. Since the electrical conductivity increases with an increase in the freezing rate, the freezing rate is previously determined by counting the same back from the relation between the freezing rate and the electrical conductivity. The continuous measurement of the freezing rate is thus permitted and the operation management and control of the tank 1 are facilitated.

Abstract: PURPOSE: To make it possible to measure the small light absorption quantity at a high speed with high precision by measuring the light absorption quantity directly and automatically considering the characteristic intensity difference between both a measurement and a reference light beam. CONSTITUTION: The measuring light beam M with wavelength λM and basic intensity IMa and the reference light beam R with wavelength λR and basic intensity IR are detected DE almost at the same time, and analog common collecting generation DE of the measuring signal UMa and basic signal URa in the form of difference generation D is performed. Consequently, the analog indication A of the intensity difference ΔI between the both as a direct measured light absorption quantity is made. An optical zero adjustment AN for it is made and the characteristic intensity difference ΔIn which attenuates to zero is automatically considered B.  Then the beams M and R are transmitted through a substance MA to be measured which is inserted into a beam path S and the beam M is absorbed by the substance MA, but the beam R is not absorbed much and its adjusted intensity IRb decreases to IMb larger than transmitted light intensity IMc . Signals UMc and URc are generated by following detection DE and the difference between those signals is generated D automatically in consideration of the difference ΔIn and regarded as a direct measured value to obtain light absorption quantity information LA on the substance MA fast with high precision.
