IPC: G06T1/00
Filed: 1999-11-22
Abstract: PROBLEM TO BE SOLVED: To provide an image position aligning method which needs only a short processing time and also can accurately align image positions. SOLUTION: In search of matching position, a correlation coefficient (or similarity) between a reference image and an object image is first calculated in a 1st type partial area, a correlation coefficient (or similarity) between the reference image and the object image is also calculated in a 2nd type partial area corresponding to a Y direction important recognition area, and an integrated correlation coefficient (or integrated similarity) is further calculated on the basis of the correlation coefficients (or similarities).  Whether or not the calculated integrated correlation coefficient (or integrated similarity) is equal to or greater than a rough search target value is judged and when it is smaller than the rough search target value, a rough search that performs calculations while moving the object image in the unit of several pixels in the partial area set in the reference image is carried out until the rough search target value is surpassed.

Title: Voltage/current conversion circuit
Inventor: UNO YOSHIO
IPC: H03F3/45
Filed: 1997-12-02
Abstract: PROBLEM TO BE SOLVED: To provide a voltage/current conversion circuit capable of holding linear characteristics of the amplitude of input/output signals, suppressing the generation of signal distortion and being operated by a low power supply voltage. SOLUTION: By extracting the DC component VD of input signals Vin by a low-pass filter constituted of a resistance element R1 and a capacitor C1, inputting it to a differential amplifier circuit AMP3, generating a voltage V2 corresponding to it and feeding it back to one of the input terminals of the differential amplifier circuit AMP1, the base potential of the transistor Q1 of the differential amplifier circuit AMP1 is held to be the same as the DC component VDC.  Since the input signals Vin are impressed through an input resistance element R2 to the base of the transistor Q1, the difference signals of the input signals and the DC component VDC are generated, an output current Vout corresponding to the difference signals is generated by the differential amplifier circuit AMP2 and thus, the DC component of the input signals is canceled and the output current Vout does not contain the DC component and depends only on the amplitude of the input signals.

IPC: H05K3/00
Filed: 1989-12-20
Abstract: PURPOSE:To make it possible to prevent lead patterns from being shortcircuited due to scratch or the like of a lead frame in a manufacturing process of a semiconductor integrated circuit device by a method wherein the lead frame is formed into a structure, in which the lead patterns are not made to project from the surface of an insulative film. CONSTITUTION:A lead frame has a structure, in which lead patterns 3C are not made to project from the surface of an insulative film 1. That is, groove patterns of a form identical to that of the patterns 3C are formed in the film 1 by etching. A conductive material, such as a copper foil or the like, is fixed by pressure on the surface of the film 1 with these groove patterns formed therein and after the conductive material is buried in the grooves, unnecessary parts are removed by etching, whereby the patterns 3C are formed. Thereby, it becomes possible that the patterns 3C are prevented from being short-circuited due to scratch or the like of the lead frame in the manufacturing process of a semiconductor integrated circuit device.

IPC: C04B38/00
Filed: 1989-12-23
Abstract: PURPOSE:To facilitate the stripping of a form from a panel having even complicated shaped solid part by a method wherein the solid part of the panel is cast by means of an aluminum mold or metal mold, on the molding surface of which aluminum powder is applied or dusted.

Calcium hydroxide Ca(OH)2 in the cement material 3 reacts with aluminum as the ingredient of the mold 2, resulting in producing hydrogen gas 4 on the surface of the mold 2 and consequently developing gas bubbles on the surface of the mold 2 so as to form gap between the surface of the groove part of the formed body made of the cement forming material 3 and the surface of the mold 2. Next, by stripping the form after the finish of pre-curing, coarse unevenness is produced on the inner surface of the each groove. The stripping of the form can be performed easily due to the presence of the gap developed by the hydrogen gas 4. No damage of panel material develops at the solid part or its surroundings.

Title: Clock-frequency modulation for secrecy protective microprocessor
Inventor: ERITSUKU SUPURANKU
IPC: H04N21/4405
Filed: 1994-12-19
Abstract: PURPOSE: To reduce the cryptograph processor vulnerability against security infringement caused from the observation of a processor timing by modulating clock signals to substantially give a series of random and also unpredictable clock pulses. CONSTITUTION: A variable frequency source (clock) 10 generates a clock signal through a periodic clock pulse. The frequency source 10 consists of analog or digital circuits. Various adjustments and selections of a clock output frequency use a substantially random modulation circuit 12 which randomly changes each pulse of clock signals to unpredictably translate the timing of continuous pulses. An unpredictable pulse stream CLK which is outputted from the source 10 is used to clock a usual cryptograph processor 14 to encrypt or decode data from a terminal 16. The modulation of clock signals is acquired by changing total delay which randomly circulates a ring.
