Abstract: An apparatus for detecting the concentration of particles in a liquid (8) includes a light-emitting portion (11) for emitting examination light (82) which is totally reflected by a boundary surface (80) contiguous to the liquid to be examined, a photosensor (12) for receiving the totally-reflected light, a reference sensor (13) for directly receiving the examination light, and a judgment portion (20) for finding the reflectance from outputs of the two sensors to compute the particle concentration. In case that the liquid to be examined is lubricating oil of an engine, the concentration of carbon particles is calculated, thereby judging the deterioration of the lubricating oil.

Abstract: A method and a device for detecting a deterioration of vehicle oil are disclosed in which the end point of the oil service life can be detected with higher accuracy, while at the same time detecting the progress of the oil condition in the vicinity of the end point of the oil service life. The acidity or basicity of the vehicle oil is measured using a pH sensor (11) generating an output in responding to the degree of the acidity or basicity. The deterioration of the vehicle oil can be detected based on the fact that with the increase in vehicle mileage, a line approximating the output of the pH sensor (11) with respect to the vehicle mileage has a tendency to change from a first inclination to a second inclination larger than the first inclination and then from the second inclination to a third inclination smaller than the second inclination.

Abstract: PROBLEM TO BE SOLVED: To enable accurate correction of temperatures by making the temperature of oil detected with an oil temperature sensor correctly reflected on output voltages of an oil degradation sensor in the oil degradation sensor with the oil temperature sensor. SOLUTION: In the oil aging sensor 1, a pair of electrodes is constituted of an inner ring electrode 14 and an outer ring electrode 15. In the oil degradation sensor 1, the oil temperature sensor 17 is also arranged inside the inner ring electrode 14.

Abstract: PROBLEM TO BE SOLVED: To provide an oil filter capable of lowering a pressure drop in relieving. SOLUTION: A relief valve 1 has a body part 10 for communicating an oil inlet part 41 with an oil outlet part 42 and a movable valve element (spring member 21) for opening and closing the communicating part 11 of the body part 10. The valve element (spring member 21) is moved in response to the pressure difference between the parts 41 and 42 and operates snapping action to rapidly change the operating state from a first operating state to close the communicating part 11 to a second operating state to open the communicating part 11.

Abstract: PROBLEM TO BE SOLVED: To provide an accelerator pedal device for a vehicle capable of maintaining a normal rotating operation of the accelerator pedal by preventing foreign matters from being remained on a support member.
SOLUTION: A surface opposed to the accelerator pedal of a mounting base 4 is formed in a projection shape, namely in an approximately dogleg shape from two planes 4a, and a surface opposed to the mounting base 4 of the accelerator pedal 2 is formed in a projection shape, namely in an approximately dogleg shape from two planes 2a. Since the foreign matters remained on the mounting base 4 can be easily removed thereby, or the remaining foreign matters can be easily removed by pedaling the accelerator pedal 2, the accelerator pedal device for the vehicle can prevent foreign matters from being remained on the support member, and maintain the normal rotating operation of the accelerator pedal.

Abstract: PROBLEM TO BE SOLVED: To provide an oil detecting apparatus that can easily fix the interval between electrodes, can reduce the number of components, can be miniaturized, and can detect the degree of deterioration of oil. SOLUTION: A first electrode 31 has a first fin 32 extended toward a projecting shaft outside a cylinder toward a second electrode 35. The second electrode 35 has a second fin 36 extended toward the projecting shaft inside the cylinder toward the first electrode 31. The numbers of fins formed in the first and second electrodes 31 and 35 are the same, and the bending angle of each fin to the original cylindrical wall position before forming each fin by cutting and bending is equal for both the electrodes, namely less than 90°. The interval between electrodes including the fin is set to 1 mm or less. Since the interval between the electrodes is nearly constant in the peripheral direction, the distribution of current density between the electrodes is uniform, and the resistance between the electrodes decreases.
