Inventor: AKAGI TOSHIO
IPC: G01B17/00
Filed: 1993-12-17
Abstract: PURPOSE:To make it possible to correct the sensitivity by transmitting and receiving a surface wave which is propagated through the surface of a body to be inspected and by comparing the height of a received pulse at that time with the height of a reference received pulse. CONSTITUTION:First, a pulse of a reference strength is transmitted from a first appropriate coil 5a out of transmission/reception coils 5, an ultrasonic wave propagated through the surface of a metal 4 being a body to be inspected is received by a second coil 5b spaced at an appropriate interval L from the first coil 5a and a reception strength at that time is measured. Based on the height Gs of a received pulse at this time and a reference value Gs0, a sensitivity correction coefficient alpha is given by the following equation: alpha=Gs0/Gs. When the height of the received pulse of a reflected wave from a defect obtained by angle-beam flaw detection is denoted by Gf, accordingly, the height of the pulse after the correction of sensitivity is given by Gf.alpha.

Title: Fuel filter device for diesel engine
Inventor: YAMADA YOSHIHIKO
IPC: F02M37/00
Filed: 1989-12-28
Abstract: PURPOSE:To prevent a filter from clogging, by forming inside a valve element a flow path which leads from a heated fuel passage to the supply passage through a thermo-sensitive valve, thereby securing a smooth flow of heated overflow fuel and raising combustion temperature sufficiently. CONSTITUTION:While an engine concerned is in operation, the overflow fuel passes through a float chamber 10 and an outlet port 13 and flows into a heated fuel passage 14. When the fuel temperature falls to a specified value or lower, a spring 25 of shape memory alloy shortens, a valve element 22 is pushed to the right by a bias spring 23 to cause a tip 22b to separate from a valve seat 21. Consequently the supply passage, out of illustration, is put in communication with the heated fuel passage 14 and the open area of a small diameter passage 14a is gradually enlarged. Thus the overflow fuel flows in the axial direction 26b from a hole 26a of a flow path 26, and then is supplied to a supply passage through a leadout hole 26c and the small diameter passage 14a. The installation of the flow path 26 inside a valve element 22 ensures that the fuel is supplied smoothly.
