Filed: 1996-08-15
Abstract: PROBLEM TO BE SOLVED: To obtain high security by an easy method by inputting fingerprint data in the form of image data, comparing the input data with previously registered fingerprint data and matching them against each other, and allowing use only when both the data match each other. SOLUTION: A fingerprint read part 2 is built in a portable terminal which has a screen display part 1. This portable terminal is equipped with a battery storage part and a control part. The fingerprint read part 2 consists of a fingerprint input part, a fingerprint feature extraction part, and a data comparing decision part. Then an operator presses the fingerprint of his finger tip against the fingerprint input part to input his fingerprint, and in this case, the fingerprint of the operator who uses this portable terminal for the 1st time is previously registered. The portable terminal main body is not equipped with a registering function because of its security, and registering operation is done by connecting this terminal to a host special device.  Then the inputted fingerprint is inputted as image data to extract feature points, and pattern matching against previously registered fingerprint data is carried out.

Title: Sorting method for lamp
Inventor: KIHARA KUNIHIKO
IPC: G01J3/28
Filed: 1987-08-31
Abstract: PURPOSE:To sort the quality of the lamp stably at all times by applying a voltage between the bulb of the lamp wherein a noble gas is charged and causing electric discharge in the lamp. CONSTITUTION:An incandescent lamp 1 is constituted by charging a mixture of 90vol.% argon gas and 10vol.% nitrogen gas in, for example, a glass bulb under pressure of 82,500Ps (room temperature). When a high voltage is applied between discharge terminals 3 and 5 from a high voltage generator 2, glow discharge is caused between the discharge terminal 3 and a filament coil 1c. The forward light of light emitted by the discharge is diffused by a light diffusing transmission plate 7 and photodetected by a sensor 8 having an optical fiber which transmits only light alpha of almost 560mm. Here, when the sensor 8 detects the light emitted by the discharge of the incandescent lamp 1, the maximum peak value corresponding to a conforming article is relatively large, but the maximum peak value corresponding to a seriously defective decreases greatly. Thus, the conforming article and nonconforming article differ in distribution, so the maximum peak value is set previously to sort the conforming and nonconforming articles.

Title: Frame detection circuit
Inventor: FUKUDA SETSU
IPC: H04Q11/04
Filed: 1986-09-13
Abstract: PURPOSE:To miniaturize a device for the titled circuit by deciding it as the leading of a frame when a reception signal is detected again after zero- consecutive period in a signal detected at a shorter period than its baud rate lapses for a prescribed period or over. CONSTITUTION:A clock 2 having a shorter period than the clock 1 of the baud rate of a reception signal and a comparator output C of the reception signal are inputted to a detection means 5. Then FFs 11, 12 and an inverter 15 read the output C at every leading/trailing of the clock, a NOR circuit 17 gives an output to keep the counter 21 in a clear state during the output period. The RC output of the counter 21 is always 0 and the clock 1 is counted up 21 via a NOR circuit 18. The counter 21 is counted up during consecutive zero period and when the number reaches a prescribed number, the RC output goes to 1, the NOR circuit 18 gives no output and the counter 21 is stopped. The FF 13 forms a latching circuit and outputs a frame pulse by a first output C after the RC output goes to 1. Thus, the device is miniaturized and LSI is facilitated.
