However, it is possible to avoid a short circuit at the tip by means of an insulating material 54 which is coated on the circumference of the side face of the probe pin 53. The insulating material 54 is coated on the circumference of the side face of the probe pin 53. However, the same effect can be expected even when an insulating tube is inserted to the same part so as to be covered. In addition, since an insulation means is installed only at the tip part of a probe 50, the cost of the probe can be reduced. In addition, the insulation means is composed of the insulating tube which is inserted on the side face of the tip part.

Title: Fingerprint confirming apparatus
Inventor: YAHAGI HIRONORI
IPC: A61B5/117
Filed: 1988-12-20
Abstract: PURPOSE:To confirm a fingerprint safely and certainly by making the front surface of a fingerprint confirming apparatus oblique and hooking the first or second joint of a finger with the ridgeline between a fingerprint image input surface and the oblique front surface and confirming that the finger is not inclined by a sensor before reading a fingerprint to output the same. CONSTITUTION:When the first joint 8 of a finger 4 is hooked with a ridgeline 6 and the finger 4 is placed on a glass plate 2 and sensors 5a, 5b, the bulb of the finger 4 presses detection electrodes 5ac, 5bc which in turn send out detection outputs upon the reception of predetermined pressure or more. At this time, when the number of the detection outputs of the detection electrodes 5ac, 5bc are equal, it is judged that said finger 4 is just placed at the center. As a result, the fingerprint image on the glass plate 2 is detected by the order from a control part and inputted. As mentioned above, since the finger 4 is present just at the center between the sensors 5a, 5b, four left and right detection electrodes are respectively pressed and the numbers of the left and right pressed electrodes are equal. If the finger 4 is placed obliquely, the number of pressed detection electrodes do not coincide left and right and no fingerprint image is inputted.

Abstract: PURPOSE:To improve the characteristic of a MOS thin film transistor (TFT) by enlarging the grain size of the polysilicon film of the bulk section (source- drain channel area section) of the TFT and, at the same time, to make the polysilicon film compact in texture. CONSTITUTION:The polysilicon film of the bulk section of a MOS thin film transistor (TFT) is formed by continuously forming a polysilicon film 3 containing a TV group metal and another polysilicon film 3 containing no impurity. The grain size of the first-layer polysilicon of the channel section of the TFT is adjusted by adjusting the introducing amount of the impurity at the time of forming the first-layer polysilicon. Therefore, the TFT can have a low turning-off current, high turning-on current, and high ON/OFF ratio. In addition, since the impurity is introduced into the polysilicon film of the channel section without performing any ion implanting process and the introducing quantity of the impurity is adjusted at the time of forming the polysilicon, the threshold voltage Vth of the TFT can be controlled.
