Stemming reduces inflected words to their stem or root form.
For example the words fishing, fished,fish, and fisher are reduced to the root word,fish,
so a search for fisher returns all the different variations
Returns only one member of a family of patents

PROBLEM TO BE SOLVED: To provide a joint connector of excellent assembling workability.

SOLUTION: A terminal lock protrusion 32 is provided on one end side of a main part 31 of a retainer 30, and a short-circuiting plate 40 is provided at the other end to face the terminal lock protrusion 32. A terminal 20 is installed on a connector housing 10, and the retainer 30 is pushed into the connector housing 10 from over, so double lock of the terminal 20 by the terminal lock protrusion 32, and short-circuiting between terminals 20 by the short- circuiting plate 40, which have conventionally been performed as separate works, can be performed by one action. Work efficiency is thus improved.

When emitted light from LED 31 is incident on photodiodes 32 and 33 with luminance Pa and Pb, currents ia and ib are generated according to luminance Pa and Pb. When outside light is incident through the finger tissues on photodiodes 32 and 33 with luminance Pc, current ic is produced. The current i1 (= ia + ic) generated by photodiode 32, and the current i2 (= -ib - ic) generated by photodiode 33, are added at node X, and the current ic corresponding to outside light is thus cancelled. In addition, photodiodes 32 and 33 are disposed at different distances from LED 31. As a result, the current flowing to opamp 34 is current ia corresponding to luminance Pa because luminance Pb is extremely low. The opamp 34 then applies a current voltage conversion to generate pulse wave signal Vm.

When the light from an LED (31) is incident to photodiodes (32 and 33) at illuminances (Pa and Pb), respectively, electric currents (ia and ib) corresponding to each illuminance are generated. When external light which arrives through the tissue of a finger is incident to the photodiodes (32 and 33) at an illuminance (Pc), an electric current (ic) is generated. The electric current (i1) (=ia+ic) generated in the photodiode (32) is added to the electric current (i2) (=-ib-ic) generated in the photodiode (33) at a node (X) and the electric current (ic) corresponding to the external light is offset. Since the photodiodes (32 and 33) are attached so that the distances from the LED (31) may be different from each other, the illuminance (Pb) is so extremely lowered that the electric current flowing into an operational amplifier (34) becomes the same as the current (ia) corresponding to the illuminance (Pa). The amplifier (34) generates a pulsating wave signal (Vm) through current-to-voltage conversion.
