Title: Character recognition device
Inventor: MORI AKIO
IPC: G06K9/62
Filed: 1987-09-30
Abstract: PURPOSE:To facilitate the inputting by moving up the candidate order of a recognized result when the input positions of characters which have been recognized based on handwriting information inputted from a position input means belongs to an area calculated from a character inputted one character before and a size, and when the character codes of respective first candidates are coincident. CONSTITUTION:When the recognition of the input character is failed when the characters are freely handwriting-inputted to the position input means 1, recognition information with respect to the character is held in a buffer 2f.

Title: High-speed searching method of rotary head type digital recording and reproducing device
Inventor: SHIROSHITA HIROYUKI
IPC: G11B15/03
Filed: 1988-09-30
Abstract: PURPOSE:To perform search at a high speed by detecting an aimed position of a tape at a searching speed which is several times as fast as the ordinary reproducing speed after feeding the tape by a fixed length at a low speed when a 1st aimed tape position is detected by a high-speed search and simultaneously changing the mode to the reproducing mode. CONSTITUTION:When the tape position information of the 1st aimed tape position or a position beyond the 1st aimed position is read while a high-speed search is performed, a system control circuit 15 immediately brakes a reel motor 3 and stops the motor 3. When the tape speed drops to, for example, a 30 times speed or under, thereafter, a capstan motor 2 is driven in such a way that the phase of the motor 2 is matched to the tape speed by means of a capstan servo circuit 11 and ATF servo circuit 13 and, at the same time, the FG pulse of the motor 2 is counted by means of a capstan FG counter 21. Upon counting a fixed count value, the tape speed is reduced to a 2-3 times speed and, when the final aimed tape position information is detected, the tape is instantaneously stopped. Therefore, the searching time can be reduced.

Filed: 1989-09-25
Abstract: PURPOSE:To obtain a high-quality SOI layer by forming an ion-unimplanted or low-implanted region at one part on a substrate by ion implantation using a mask and then by forming an SOI region with this region as a recrystal nucleus. CONSTITUTION:A thick-film silicon oxide film 2 which prevents oxygen ions to be implanted from being passed or reduces the amount of transmission is accumulated on the surface of a silicon substrate 1 and is subjected to patterning. Then, when oxygen ions (approximately 2X10<18>/cm<2>) are implanted, a region 4 which is implanted to a depth of approximately 0.45mum in high concentration is formed. At the same time, an ion-unimplanted or low-implanted region 5 remains directly below a mask (silicon oxide film) 2 for preventing implantation at the same time. Then, after eliminating the mask 2 for preventing implantation, the substrate 1 is subjected to heat treatment at a high temperature of approximately 1000-1400 deg.C, a buried oxide film layer 6 is formed in a region where highly concentrated oxygen ions are implanted. The region which is damaged due to the implantation is subjected to crystal growth with an unimplanted or low-implanted region as a core of crystal, thus obtaining an SOI layer with improved crystallizability.

Filed: 1993-08-28
Abstract: PURPOSE:To surely weld a part to the correct position of the steel sheet part by matching welding position display mark of the steel sheet part with an irradiation mark and setting the relative position between a fixed electrode and the steel sheet part. CONSTITUTION:When an operator mounts the steel sheet part 13 on the fixed electrode 1 with the hands, the surface of the steel sheet part 13 is irradiated with the irradiation mark.
