Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To improve the operability by integrally mounting devices such as a finger collating input device on various markers of model names, etc., stuck or printed on a casing surface to make the marks conspicuous and let a user recognize the presence of the respective devices while recognizing the marks. SOLUTION: A model number tag 12 is stuck on the casing of a portable PC, and a linear metal conductors of the finger collating input device 11 are embedded in characters S constituting the model number tag 12 and mounted on the casing surface. When a finger for signal detection is pressed in the electrode array direction, i.e., along the length direction of an electrode array, the resistance value of the finger surface between adjacent electrodes is read in order by switching analog switched along the length direction of the finger. When the finger is pressed against (n) electrodes, the resistance value between the electrodes varies with the contact area of the finger brought into contact between the adjacent contact electrodes. Thus, the collation device performs comparative collation with a previously registered finger database to specify the individual.

Title: Monostable multivibrator circuit
Inventor: HAYAKAWA MITSURU
IPC: H03K3/0231
Filed: 1986-03-18
Abstract: PURPOSE:To prevent the pulse width of an output signal from being changed due to temperature change by combining set/reset flip-flops set by an input trigger pulse and reset by an output of two sets of comparators. CONSTITUTION:In supplying an input trigger pulse (a) to a signal input terminal 1, a transistor (TR) Q1 discharges a storage charge of a capacitor C1 rapidly. When a terminal voltage Vc of an inverting input of the comparator 5 reaches a reference voltage V1, the set/reset flip-flop 3 is reset, the TR Q1 is changed from the conducting into the nonconductive state and the capacitor C1 in the time constant circuit 7 is charged. When a terminal voltage Vc of the non- inverting input of the comparator 6 reaches a reference voltage V2, the set/reset flip-flop 4 is reset. Thus, every time the input trigger pulse (a) is fed to the signal input terminal 1, a prescribed pulse width of output signal (f) is sent to an output terminal 2.
