Title: Apparatus for inspecting capacity of flaw detection probe
Inventor: MIZUNO MASASHI
IPC: G01N27/90
Filed: 1983-04-01
Abstract: PURPOSE:To make it possible to certainly inspect and evaluate the capacity of a probe, by rotating a flaw detection reference member having the same cross- sectional area as a surface to be subjected to flaw detection and a reference flaw at a predetermined speed while allowing the flaw detection probe to oppose to said member. CONSTITUTION:A disc 10 as a flaw detection reference member is supported by a support apparatus 12 and rotated toward a constant direction at a predetermined speed by a drive motor. The outer peripheral shape of the disc 10 is the same as the shape of the surface to be subjected to flaw detection being the side surface of a flat rolled steel material and a definite reference flaw 24 is formed to a reference surface 22. On the other hand, a flaw detection probe 18 is held by a holding apparatus 18 so as to be spaced apart from the disc 10 at a predetermined interval. By this mechanism, because the relative speed of the flaw detection probe 18 and the flaw detection reference member can be made same to the relative speed of an actually running member and the flaw detection probe, a condition almost coincided with an actual flaw detecting condition is obtained and the capacity of the flaw detection of the flaw detection probe 18 can be certainly inspected and evaluated.

Title: Control of valve timing for internal combustion engine
Inventor: YAMAZAKI HIROBUMI
IPC: F02D13/02
Filed: 1993-03-18
Abstract: PURPOSE:To change the intake air timing so that generating torque can be changed in response linearly to throttle valve opening. CONSTITUTION:Target torque TQ required by a driver is found (n1-n3) from throttle valve opening (theta) and rotational speed NE of an internal combustion engine, and a spark advance quantity SA of the intake air timing is found (n4) from this target torque TQ and the rotational speed NE. Thereby, when the intake air timing is found (n5) from an intake air quantity by using an air flow meter, since the intake air quantity is saturated, a linear feeling is not produced in obtained torque, on the one hand, when the target torque TQ is used, even if the intake air quantity is saturated, the linear feeling can be given to generating torque.

Abstract: PURPOSE:To enhance classification precision of particles, by providing a submerged weir to the inside of a slurry layer of a particulate side positioned before the takeout port of slurry of the particulate side so that the submerged weir crosses the flow direction of the slurry of the particulate side. CONSTITUTION:A perforated plate 8a in which the central part is cut off and slits 9 are provided along the circumferential direction is provided just under a takeout port 5a and a submerged weir 7 is constituted so that it crosses the equilibrium liquid surface S of slurry. By this constitution, even when slurry 6 of a raw material fed to the inner circumferential face side of a rotary bow 2 from a supply pipe 4 of slurry is flowed short-circuitously in the direction of the takeout port 5a along the equilibrium liquid surface S, it is inhibited by the submerged weir 7. As a result, the slurry 6 of the raw material is once made confluent in slurry 6a retained in the rotary bowl 2. Then it is flowed upward in the direction shown in an arrow A1 while being subjected to classifying action resulting from centrifugal force and successively flowed to the takeout port 5a through the slit 9. By such a way, the short-circuitous flow in the direction of takeout port 5a is inhibited and the slurry 6 of the raw material is surely classified while maintaining constant settlement depth by the submerged weir 7 and holding the retention time.
