摘要： PROBLEM TO BE SOLVED: To obtain an oil tester by which the degradation degree of an oil can be discriminated properly by transducing an electric signal into a sound- wave signal with a sound-wave transmitting element, transmitting the signal into the oil, receiving it with another sound-wave transmitting element and transducing it into an electric signal and judging the degradation degree of the oil from an output. SOLUTION: An electric signal, at about 20kHz or higher, which is transmitted from a transmitter 2 is amplified by an amplifier 3, an electrostrictive element 4 for transmitting is excited, and ultrasonic waves are generated. The ultrasonic waves are propagated inside an oil which is put into an oil tank 5 for measurement, they are received by an electrostrictive element 6 for reception, their electric signal is detected by a detector 7 so as to be amplified by an amplifier 8, and its voltage level is displayed by an indicator 9. The level is compared with a level in the case of a new oil, and the oil is judged to be degraded when the voltage level is low. In this manner, the degradation of the oil can be judged on the basis of change in the propagation factor of the ultrasonic waves without being affected by a coloring component or the like, and the existence of the degradation can be judged properly and simply.

摘要： PURPOSE:A holder, whereby a round shape object, with a different diameter, can be made holding without changing its center position, and made centering at low cost with ease. CONSTITUTION:A small holding disk 1-3, having the same diameter, is assembled in place between disks 13, 14, having holes 11 of diameter enough bigger than an expected diameter range of a round shape object 10 to be made holding. And each center of the above described small disks 1-3 is located, from center of the hole 11, on the same circuference, in a position with its circumference equally divided into three, simultaneously to each small disk 1-3, on the line connecting the each center to the hole 11 center, is installed a rotatory axis in a direction of the disk 13 with a point 4-6, ecdentrically located from center of the hole 11 in the same direction by the same dimension, being the core axis, and a rotsation is made capable around the bearing on a point corresponding to the disk 13. Moreover, a position of each vertex of each small disk 1-3, when parallel shifting a congruent triangle to the regular triangle produced when connecting each point of the above described rotary axis 4-6, is made for the numeral 7-9, and linked to the corresponding point on the disk 14.

摘要： PURPOSE:To detect the degree of delayed speed as a crank shaft rotation angle number by measuring the goodness of ignition timing and the delay of speed for any other cylinder by utilizing an existing timing mark to show the ignition timing of the first cylinder of engine to the measured. CONSTITUTION:With 4-cycle and 4-cylinder engine, an electromagnetic sensor is attached to the third cylinder, for example. An ignition timing signal from the sensor is sent to a 1/N divider and a N advance counter through a wave-form shaper. The divider divides standard signal during repeated one cycle of ignition timing signal according to the cylinder number N, and its output is divided by the standard signal at a divider. The N advance counter selects an output signal delayed by a angle corresponding to a crank shaft rotation angle until the time from the dispatch of the said ignition timing signal to the ignition of the first cylinder and a timing light is illuminated. And, operator observes if timing mark coincides with a matching mark to measure the goodness of ignition timing.
