Abstract: A system diagnosis apparatus comprises a communication processing device which acquires a utility rate of the system resources of a user system and a queue for the system resources, a memory device stores thresholds of the utility rate and the queue. An analysis device is provided which decides that the performance of the system resource has lowered when the utility rate is more than its threshold and the queue is shorter than its threshold, or decides that the number of system resources is insufficient when the utility rate is more than its threshold and the queue is longer than its threshold.

Abstract: A process for producing a vibration isolator. The process involves steps of forming an intermediate product including an axial member, an outside member having a cylinder-shaped portion and a rubber elastic member, and drawing the cylinder-shaped portion with a drawing apparatus provided with a drawing hole at least by pressing the cylinder-shaped portion into the drawing hole. The drawing hole has a predetermined dimensional diameter being smaller than an outer peripheral diameter of the cylinder-shaped portion. Thus, the cylinder-shaped portion is reduced diametrically to plastically deform. The production process can obviate the conventional pressed-in construction in which metallic members contact with each other, can make the manufacture of the vibration isolator easy, and can reduce the manufacturing cost.

Abstract: A motor gasoline composition for use in automotive vehicles is disclosed. A selected gasoline fraction is combined with a specified amount of a selected alkali earth metal salt whereby plug fouling inhibiting ability is greatly improved.
