Title: Waste heat recovery device of internal combustion engine
Inventor: ENDO TSUNEO
IPC: F01N5/02
Filed: 2001-01-10
Abstract: PROBLEM TO BE SOLVED: To sufficiently recover waste heat from two temperature rising parts generated on an internal combustion engine by driving. SOLUTION: First and second temperature rise parts 202, 204 are generated on the internal combustion engine 1 by driving. The first temperature rising part 202 has the higher degree of temperature rise than that of the second temperature rising part 204. A first evaporation part 205 of an evaporation means 3 makes use of the first temperature rising part 202 to generate first steam with the raised temperature. A second evaporation part 206 makes use of the second temperature rising part 204, to generate second steam having the raised temperature and pressure lower than that of the first steam. A first energy converting part 207 of a capacity type expanding machine 4 converts expansion energy of the first steam into mechanical energy. A second energy converting part 208 converts expansion energy of the second steam into mechanical energy.  Both mechanical energies are integrated and output. A condenser 5 liquefies the first and second steams with dropped pressure. A supply pump 6 pressurizes and supplies liquid from the condenser 5 to the first and second evaporation parts 205, 206.

IPC: G01M15/04
Filed: 2001-01-24
Abstract: PROBLEM TO BE SOLVED: To exclude effects of air's average pressure, fluctuation value of the pressure, etc., caused by various factors when a compressed air is supplied to a lubrication system of an engine to judge whether an element related to the engine lubrication system is correctly assembled or not based on a change in an air pressure. SOLUTION: An air is supplied to an lubricant path of an engine while a crank shaft of the engine is rotated, and a change in pressure of the supplied air in the engine is measured according to a rotational angle of the crank shaft. The values acquired hear are divided into A, B, C, and D. Defects of a crank pin metal is detected based on an amplitude after correction, at phases A and C not corresponding to an action timing of an oil jet. The amplitude after correction is acquired by considering the effect of average pressure at the phases A and C on amplitudes aA and aC (actual measurement value) at the phases, for appropriately removing effect. Thus, a defective product of crank pin metals is accurately discriminated.

Title: Rolling bearing
Inventor: TAKEHARA TORU
IPC: F16C33/46
Filed: 2001-02-08
Abstract: PROBLEM TO BE SOLVED: To secure sufficient through oil quantity (pump action) not only when a bearing back face side (small diameter side; oil supply side) oil surface height is high but also when the height is low to reach below the vicinity of a bearing back face side rolling element PCD. SOLUTION: In a rolling bearing having a contact angle, a difference in level 5 of a bearing back face side inner diameter surface of an outer race 1 is eliminated by a height (Y) or 'back face side cage inner diameter' >='back face side rolling element PCD' is set instead of the elimination, a bearing back face inner end part 6 of a flange of a cage 4 is eliminated and a flange inner diameter is increased.
