Title: Method and device for recognizing handwritten character
Inventor: SAKAI YOSHIFUMI
IPC: G06K9/62
Filed: 1994-08-04
Abstract: PURPOSE:To accurately segment characters without performing a projection operation to ink data in on-line handwritten character recognition without input frames for low stroke number characters. CONSTITUTION:This device is provided with a character recognition engine part 14 for taking out one stroke in the order of input by a user from an ink data storage part 13, performing comparison and collation with a recognition dictionary 17 along with an already taken-out unsegmented stroke, obtaining a candidate character and a recognition error amount corresponding to the candidate character and weighting the recognition error amount when the candidate character is the character capable of being the partial graphic element of the other character. The character recognition engine part 14 repeatedly executes the search of the candidate character until a prescribed stroke number is reached and thereafter, discriminates the candidate character corresponding to the minimum one of the obtained recognition error amounts as a recognition character and segments the character.

Title: Fault detection system
Inventor: FUKUI MASASHI
IPC: G06F11/00
Filed: 1987-07-24
Abstract: PURPOSE:To detect the runaway of software by hardware by deciding whether or not a value incremented for each execution of the instruction and reset by the software reaches a prescribed value in the operand memory. CONSTITUTION:An environment identifier stored in an input packet register 21 is used as an address via an address register 23 in an operand memory at the start of instruction and data corresponding to the address is read from a counter memory 24 and written again in the memory 24. On the other hand, when a counter memory part corresponding to the environment identifier or the instruction code is a reset instruction, an operand memory control circuit 22 resets the data register 28 before reaching the overflow value to set an initial value to the counter memory. However, when the value reaches the overflow value, it is informed to the circuit 22, then the circuit 22 recognizes the occurrence of runaway of the software.

Abstract: PURPOSE:To form a punch through stopper localized inside a substrate without complicating a manufacturing process, by composing an insulation layer to form a punch through stopper between source and drain regions more deeply on a surface layer of a semiconductor substrate. CONSTITUTION:A field oxide film 2 and a channel stopper layer 11 are formed, and next a dry etching technique is used to dig a groove 3 on one part 23 of a region where an active region of an Si substrate 1 is formed.

Title: Delay suppressing system for subscriber's line transmission system
Inventor: KOIZUMI NOBUKAZU
IPC: H04M3/00
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To provide a stable transmission system of a large margin to noises by using a telephone line as a transmission line, transmitting data through a modulate signal, for which quadrature amplitude modulation is respectively performed to plural frequency modulated carrier waves, and providing a means for minimizing the delay of data transmission by optimizing the capacity of line transmission. SOLUTION: A received signal is demodulated by a demodulator 210 of DMT modulation, a reference signal generated by a reference generating circuit 220 is subtracted, and the received signal becomes the ERROR signal of a noise component for each carrier. An S/N measuring instrument 230 calculates the S/N of each carrier from the ERROR signal and a transmission bit number converter 240 converts this S/N to the number of bits to be allocated by the S/N value of each carrier. At such a time, the converter 240 prepares a bit map so as to minimize a prescribed expression in order to minimize the number of dummy bits. Thus, conversion delay time caused by dummy bits is minimized and the amount of transmission delay can be suppressed.

Title: Semiconductor device and its manufacture
Inventor: SHIBATA AKIHIDE
IPC: H01L27/092
Filed: 1999-06-29
Abstract: PROBLEM TO BE SOLVED: To enable rapid operation so as to provide a sufficient substrate bias effect and restrain off-leak within the allowable range by selecting the ion implantation amount and implantation energy during formation of a shallow well region. SOLUTION: Althrough a maximum implantation amount can be raised if the degree of recovery of crystal defect changes due to the temperature in a heat treatment process, after ion implantation and a heat treatment is carried out at a higher temperature, minimum implantation energy is set to prevent punch-through between a source region and a drain region, and a deep well region. Since reverse and forward leak current generated in a P-N junction can be restrained by forming a shallow well region, it is possible to restrain off-leak of an N-type or P-type transistor and also to realize a low threshold which is necessary for low voltage drive. Therefore, it is possible to restrain reverse and forward leak current in the P-N junction and to obtain a low threshold which is necessary for low voltage drive by restraining off-leakage of an MOSFET.

Title: Telephone line switching and control circuit
Inventor: SHIBUI MICHIROU
IPC: H04N7/173
Filed: 1983-10-01
Abstract: PURPOSE:To attain the sure switching of a telephone line by confirming the incoming of a carrier of an outgoing data signal simultaneously when the average amplitude of the outgoing data signal is detected. CONSTITUTION:Since the average amplitude level of an output of a limiter amplifier circuit 37 is made higher than a preset level when the outgoing data signal is incoming normally to an information receiver 6, the output of logical 1 is obained at an amplitude detection circuit 38 and the output of logical 1 is obtained at a carrier detection circuit 40 because the carrier of the outgoing data signal is extracted from a band pass filter 39 at the same time. As a result, a switching operation signal is given to a line switch 4 from a drive circuit 43 as the output of a telephone line switching control circuit. If no outgoing data signal is incoming, even when the component of a comparatively large level due to noise is superposed, the output of the carrier detector does not go to logical 1 to cause no malfunction of changeover.
