Title: Female type terminal fitting
Inventor: IKEDA TOMOHIRO
IPC: H01R13/42
Filed: 1993-01-08
Abstract: PURPOSE:To reduce the insertion force of a terminal fitting to a terminal housing chamber without lowering the holding force of a female type terminal fitting to the terminal housing chamber, by forming a tilted part, along an insertion direction to a terminal housing chamber, on the bottom surface side tip part of an elastic folded part. CONSTITUTION:When a female type terminal fitting 21 is inserted in a terminal housing chamber 13, a tilted part 25, formed on the bottom surface tip part of an elastic folded part 23, abuts on a part 17 to be slided to bend an arm 15 when a flexible locking arm 15 is locked. In this case since the elastic folded part 23 is protruded from a bottom surface, the arm 15 is gradually bent by a part 25 due to the insertion of the fitting 21 to a chamber 13 to reduce the insertion force of the fitting 21 to the chamber 13. Then the locking part of the arm 15 is inserted in a locking hole 5 on a bottom surface to hold the fitting 21 by the chamber 13. In this case, since the length of the arm 15 is not required to be lengthened, the holding force of the fitting 21 is not lowered. Consequently, since the insertion force of the fitting 21 to the chamber 13 can be reduced, the assembly operability of the fitting 21 to the chamber 13 can be improved.

Title: Detection of hue
Inventor: KITAGAWA KATSUICHI
IPC: G01J3/50
Filed: 1988-01-08
Abstract: PURPOSE:To inexpensively and automatically detect the hue of an object to be detected, by successively inputting other two image signals to a white and black image processor only when the object to be detected is detected and detecting the hue of the object to be detected on the basis of each brightness. CONSTITUTION:A white and black image processor 6 searches an object 10 to be detected according to a searching mode. When the object to be detected is present, the processor 6 calculates a particle size, a presence region and average brightness at every object to store them in a memory. Then, the processor 6 enters a hue detection mode. The processor 6 outputs a control signal to change over a signal change-over device 5 to a contact 5c and changes over the image signal from a color camera 4 to the processor 6 from a green image signal, for example, to a blue image signal. The processor 6 calculates the hue at every object from green, blue and yellow image signals to output the corresponding hue signal. By this method, the hue of the object to be detected is detected inexpensively and automatically.
