Title: Fingerprint collating device
Inventor: MORITA KOICHIRO
IPC: G06K9/00
Filed: 1989-08-23
Abstract: PURPOSE:To enable collation by inputting one arbitrary fingerprint and to improve the degree of freedom by managing pattern feature data concerning the registered fingerprints of plural fingers of the same registered person respectively corresponding to a registered person identifier. CONSTITUTION:A pattern feature data file 21 manages the respective pattern feature data concerning the registered fingerprints of the plural fingers of the same registered person corresponding to identification symbols including the registered person identifier and a finger identifier. When the identification symbols including the registered person identifier and finger identifier, and the picture of the fingerprint as the object of collation are inputted, a collation processing part 18 discriminates whether the pattern feature data corresponding to the inputted identification symbols exist in the pattern feature data file 21 or not. When the data are not existent, the response of refusal is outputted. When the data are existent, the existent pattern feature data corresponding to the identification symbols are collated with the pattern feature data concerning the pattern feature of the inputted fingerprint picture and a collated result is outputted. Thus, at the time of collation, the collation can be executed by inputting the fingerprint of the arbitrary finger out of the plural fingers.

Abstract: PURPOSE:To correct secular changes in the sensitivity of an ECT apparatus efficiently, by correcting a cross calibration factor from a relationship between the total counts at the cross calibration and those at present. CONSTITUTION:As shown in the Fig. (a), a pool phantom 2 is arranged at a tunnel section 11 of a position ECT apparatus to collect data.

Title: Voltage stabilizer
Inventor: TAKAYAMA TOMIO
IPC: G05F1/56
Filed: 1982-12-10
Abstract: PURPOSE:To reduce considerably a driving electric power by using a field effect transistor FET as a main control element in a series-type voltage stabilizer. CONSTITUTION:An FET Q1 is used as the main control element to the voltage stabilizer. A resistance R5 is connected in parallel between the source and the gate of the FET Q1. The current flowed to the resistance R5 is controlled in accordance with the variation of an output voltage E0 to change the voltage between the source and the gate of the FET Q1, and the voltage applied across the source and the drain of the FET Q1 is varied to stabilize the output voltage E0. Since the FET Q1 is used as the main control element in this manner, the device is protected from the reverse voltage, which is generated by short-circuit of an input power source, by a backward diode incorporated in the FET Q1. The resistance between the source and the gate of the FET Q1 is high, and the driving power of the voltage stabilizer is low. Thus, the driving power is reduced considerably.

This vacuum shell 2 consists of a facade plate 4, a back plate 5 made from metal plate, side walls 6, and a reinforcing frame 7, which are fixed airtightly by low melting point solder glass. Here the height Z6 of the side walls 6 is related to the height Z3 of the electrode body 3 so that Z3-Z6=0-0.5mm including dimensional dispersion of the side walls 6 and electrode body 3. According to this construction any greater force than the one due to atmospheric pressure will not be applied to the side walls 6 even when the display device 1 is vacuum exhausted.

Title: Date controller
Inventor: TANAKA MIYUKI
IPC: G06Q10/00
Filed: 1985-09-30
Abstract: PURPOSE:To eliminate a complicated job for confirmation of dates and to facilitate an easy operation of transactions by displaying the date for confirmation as soon as a power supply is applied to perform the input of the transaction data at an accurate time point and switching the display to the transaction data. CONSTITUTION:When a power supply is applied by a power supply application means 1, a data is supplied to a display means 5 for display from a timepiece means 4 via a switching means 6. When the displayed date is correct, the transaction data is immediately supplied to a transaction means 2 by an input means 3 without having any operation for confirmation of the date. When the transaction data is supplied to the means 2, the means 2 transmits a switch request signal CRS after discriminating the input of the transaction data. Receiving the signal CRS, a switch means 6 switches the means 4 to the means 2. Thus the means 6 supplies the transaction data given from the means to the means 5 and displays it there.

Title: Semiconductor substrate
Inventor: KUSAKABE KENJI
IPC: H01L21/322
Filed: 1988-08-30
Abstract: PURPOSE:To remove dust generation, to elevate a getter effect and to enable its effect to be maintained even if it is heat-treated by dispersing carbon into one face of a semiconductor wafer having two faces. CONSTITUTION:Carbon is accumulated, by sputtering which uses carbon as a target material, on the face 2B of a silicon single crystal wafer, and subsequently the accumulated carbon is diffused into silicon single crystal by heating, and the left carbon is removed by dry etching so as to make a diffusion layer 4. Since a semiconductor substrate formed this way does not require formation of a mechanically distorted layer, there is no irregularity in the face 2B, and accordingly dust does not occur. Also, diffused carbon, since the atom diameter is different from that of the silicon, produces crystal distorsion and acts as a catalyzer of precipitation of oxygen. Minute defects induced by heat or heavy metal pollution which occurs at the face 2A during manufacturing process is enclosed in the diffusion layer and in oxygen precipitated defects, and crystal property in the region near the face 2A where a circuit is formed can be made favorable. Also, even if it is heat-treated, the getter effect can be maintained.

In this case, no intensive sense amplifier is not required. While the potential of a level L of an outside bit line BL01 is transferred to a middle bit line BL11. Then sense amplifiers SA0, 1... are driven and the potentials of the middle bit lines are amplified. Then a prescribed memory cell is refreshed via the line BL01.
