Abstract: PURPOSE:To improve the accuracy of the flaw estimation of a pressure container, etc., by obtaining a picture concentration in the estimation area of the prescribed dimensions from a flaw detection plane picture for each flaw detecting area, and estimating the flaw depth from the relation of the picture concentration and the flaw depth which is prepared beforehand. CONSTITUTION:The scope to detect a flaw of the inner surface of a pressure container 10 is divided into a unit area 18 of the prescribed dimensions, and an ultrasonic wave makes incident diagonally and scans from a probe 1 of a hand scanner 11. An ultrasonic echo received by the probe 1 is inputted into an ultrasonic flaw detecting device 12 and a flaw signal is transmitted. Next, at a video control device 13, the video signal of the cross section and a plane picture are outputted by a flaw signal and a position detecting device 5, and displayed at monitoring television sets 14 and 15. Next, from the picture concentration divided at an estimation area 19, a flaw depth is estimated by the relation of the picture concentration and the flaw depth prepared by experiment data beforehand. Thus, the flaw can be estimated with a good accuracy from the external part simply during the using of a pressure container, etc.

Abstract: PURPOSE: To prevent fretting from occurring by a method wherein immersion sulphurizing-nitriding treatment excellent in antifriction property applied to the member in contact with the outer race of a thrust bearing in a variable speed gear provided with a crusher body on the upper side.  
     CONSTITUTION: In a variable speed gear for a crusher to crush coal etc. the driving force from a prime mover is transmitted to an output shaft 7 through a large gear 6 and the upper crusher body is rotated and driven by the rotation of the output shaft 7. At this time, thrust load is given to the thrust bearing 11 from the rotating part of the crusher body through the output shaft 7 but this thrust load is absorbed by the lower gear casing 10. In the device so designed, a metallic layer 12 is constituted by the immersion sulphurising-nitriding treatment excellent in antifriction property on the surface of the lower gear casing 10.

Title: Method for continuously casting al-li alloy
Inventor: OKA KAZUYOSHI
IPC: B22D11/00
Filed: 1988-03-11
Abstract: PURPOSE:To improve casting speed and to restrain the development of shrinkage hole by using fluidized bed fluidizing solid grains at the time of cooling a cast billet drawn from a mold. CONSTITUTION:Molten metal supplied from a nozzle 1 is primarily cooled in the mold 3 circulating cooling water through an inlet 6 and an outlet 5 and the solidification is immediately started. Solidification of the molten metal in the mold is progressed while forming the solid-liquid coexisting zone 20 between the liquids level 18 and the solids level 19. The cast billet 11 drawn from the mold 3 is secondarily cooled with the fluidized bed 8. As this secondary cooling is cooled more intensely than the conventional method with only the above primary cooling, the solids level 19 in the cast billet is ascended and approached to the liquids level 18. In this result, the solid-liquid coexisting zone 20 is shorter than the above conventional method and growth of shrinkage hole developing in this zone is restrained. Further, in the result of ascending the solids level 19, the casting speed can be increased.

Filed: 1989-03-10
Abstract: PURPOSE: To reduce harmful components caused by unburned hydrocarbon by forming a surface region of a piston crown into a flat impact area lying opposite an overflow bore and running orthogonally with respect to a jet direction of a ignition beam. CONSTITUTION: An overflow bore 7, which connects an auxiliary combustion chamber 6 to a main combustion chamber 5, is positioned concentrically with respect to a longitudinal center axis 8 of a cylinder. Further, a surface region of a piston crown 3 is formed as a flat impact area lying opposite the overflow bore 7 and running orthogonally with respect to a jet direction of a ignition beam 10. As a consequence, a top land clearance 14 is shielded from unburned gas mixture by a flame tongue 11, and in association with the movement of a flame face wave 13, the unburned gas mixture is prevented from being pushed into the top land clearance 14. Therefore, unburned hydrocarbon in exhaust gas is remarkably reduced.

Title: Magnetic recording medium
Inventor: OKAZOE AKIRA
IPC: C09D7/12
Filed: 1985-03-20
Abstract: PURPOSE:To improve sufficiently the abrasion resistance of a magnetic layer by incorporating both the fine powder of a fluororesin and nonmagnetic powder having more than specified Mohs' hardness into the magnetic layer. CONSTITUTION:The fine powder of tetrafluoroethylene, for example, is appropri ately used as the fluororesin. The fine powder of such fluororesin has excellent lubricity, hence the friction coefficient of the magnetic layer when the resin is incorporated is reduced and the abrasion resistance of the magnetic layer is improved. Since the nonmagnetic powder having an excellent buffering action and having <=6 Mohs' hardness is jointly used, the crushing of the nonmagnetic powder or other fillers due to the nonmagnetic powder having >=6 Mohs' hard ness can be prevented by the action of the fluororesin fine powder to buffer the impact force, the dispersibility of the magnetic powder is not deteriorated and hence deterioration in the magnetic characteristic or the electromagnetic transducing characteristic can be satisfactorily prevented.

Title: Slip control device
Inventor: TSUYAMA TOSHIAKI
IPC: F02D29/02
Filed: 1990-03-07
Abstract: PURPOSE:To prevent shortage of a feeling of acceleration by decreasing the reduced amount of engine output obtained by an output control means at the time of slip control below that at the time of usual travel when an ascending slope travel of a vehicle is confirmed from a signal of an inclination degree detecting means. CONSTITUTION:A control unit UTR for slip control performs control of braking force of rear wheels 2L, 2R at the time when a slip occurs, and it simultaneously performs output control for reducing driving torque of an engine 3. When it is confirmed that a vehicle travels on an ascending slope, in accordance with a detection signal of an inclination degree detecting means 46, the controlled amount of engine output at the time of slip control, that is, the throttled amount of a sub-throttle opening adjusting mechanism 34 is reduced compared to that at the time of usual travel. Thus, the following disorders can be prevented: engine output is largely decreased at the time when the vehicle travel on an ascending slope; a feeling of acceleration is lost due to shortage of driving torque of driving wheels; rapid acceleration is unable to be obtained at the time when the vehicle is accelerated again.
