Filed: 1986-02-18
Abstract: PURPOSE:To improve a recognizing ratio regardless of the variable density of a printing by providing a density detecting circuit to detect the density of a density mark printed to a slip and a threshold control circuit to control the threshold of a binarization circuit with an output. CONSTITUTION:The output of a photoelectric converting circuit 1 is inputted to a binarization circuit 2, the voltage and a threshold voltage are compared, outputted as a binarization digital signal and stored in to a memory 3 as the signal of one unit at every dot. The density mark is printed to a reading posi tion independently to the first row of a reading slip. A density detecting device 5 reads the data of the mark from the memory 3, executes the density detection, compares with the suitable number of the dot, calculates the correcting value of a threshold from a mutual relation with the threshold and a threshold control circuit 6 adds and subtracts the correcting value voltage to the threshold voltage of the binarization circuit 2. Thus, the recognition ratio of the optical character reader can be maintained irrespective of the variable density of printing of the slip.

Title: Low-noise multicore parallel-cord current detector
Inventor: YAMADA KAZUO
IPC: G01R33/09
Filed: 1999-01-04
Abstract: PROBLEM TO BE SOLVED: To obtain a low-noise multicore parallel-cord current detector with which a current flowing in a parallel cord can be detected safely and simply, in a state in which an electromagnetic inducted noise at the outside is reduced by a method wherein a noise signal from the outside is guided to a cylindrical magnetic body in which a coil having a magnetic core is provided. SOLUTION: In this current detector, a parallel cord 1 is sandwiched between a half 21 and a half 22 of a cylindrical magnetic body 13, which is provided with a coil 8 having a magnetic core. Then, when a current a2 and a current b3 flow into the parallel cord 1, lines of magnetic force are passed through the core in the current of the cylindrical magnetic body 13, an electromotive force is generated in the coil 8, and an electric signal is obtained. At this time, lines of magnetic force from the outside, which becomes a noise reach the coil 8 and influences the electrical signal as noise. However, by making the lines of magnetic force from the outside to be guided to the cylindrical magnetic body 13, it made hard to reach the coil 8, and the noise can be reduced.  Thereby, without cutting signal lines, the electrifying state of an electrical apparatus and the strength of a signal can be detected simply.

Abstract: PURPOSE:To improve high-speed performance and low power consumption properties and to ensure large memory capacity by using MOS elements to form the memory parts of an address array and a data array and using a composite circuit of bipolar and CMOS elements to form a peripheral circuit part. CONSTITUTION:The MOS elements are used to form the memory parts of an address array 1 and a data array 2 respectively. While a composite circuit of the bipolar and CMOS elements are used to form a peripheral circuit part excluding the memory parts. In other words, the memory part where the number of elements plays an important role is formed with the MOS element. As a result, a high-density constitution is attained with low power consumption. Furthermore, a constitution which excels in the high-speed performance with the comparatively low power consumption is secured for a peripheral circuit part like a decoder, a driver, etc., owing to the high driving force and the high-speed performance of the bipolar element and the low power consumption properties of the CMOS element. Thus it is possible to ensure the excellent low power consumption properties as well as the high-speed performance that can cope with even a high-speed MPU. Then the large memory capacity is secured for a cache memory.

Abstract: PURPOSE:To cancel a change in a threshold level by inserting and connecting at least one of excess elements in CMOS elements not joined to a prescribed gate array to a CMOS gate array. CONSTITUTION:A threshold voltage is adjusted by connecting at least one of CMOS elements 9 not joined to a prescribed gate array in parallel or series with elements of the gate array 8 at the side of a power supply 3 or a ground 4 of the gate array 8.
