Title: Bar code reader
Inventor: TASHIRO MARIE
IPC: G06K7/10
Filed: 1990-09-14
Abstract: PURPOSE:To automatically execute the ON/OFF control of a projection part/ laser light source by arranging a proximity sensor for measuring a distance from a bar code and starting the reading of the bar code based upon information outputted from the sensor. CONSTITUTION:The proximity sensor 7 is arranged in the front of a body so as to receive reflected light from a target 6 to be detected by a photodetecting part 10 arranged in the range of a distance (d) from the sensor face. When a distance from the sensor 7 up to the target 6 becomes shorter than the value (d), a signal processing circuit 11 outputs a detection signal and a microprocessor (MPU) 4 commands o turn on the projection part/laser light source 1 to irradiate the target with laser beams. The reflected light from the target 6 is photodetected by a photodetecting part 3 and converted into an electric signal, the MPU 4 processes the fetched inputted electric signal, decodes the signal as bar code information, and when the decoded result is OK, the MPU 4 turns off the laser light source 1. Thus, the ON/OFF control of the projection part/laser light source 1 can be automatically executed and working efficiency can be improved.

Title: In-vehicle serial data communication system
Inventor: MORI HIROKI
IPC: H04L25/49
Filed: 1991-08-29
Abstract: PURPOSE:To accelerate serial communication. CONSTITUTION:Since delay time tH due to a CR is almost equal by measuring edge time in the same direction at an input pulse, serial data communication is enabled without considering the CR delay time and since the least significant bit(LSB) of data can be reduced, a data cycle T can be reduced. Then, the communication can be executed at high speed. Since the duty ratio of a data pulse is set to 50%, concerning noise judgement, the data are not considerably erroneously judged by releasing error due to difference between start delay time and end delay time.

Filed: 1997-09-10
Abstract: PROBLEM TO BE SOLVED: To enable the easy square form of Japanese syllabary (KANA) reading input of English characters or numerals by providing a key which starts a prescribed conversion program at the time of pressing and converts English characters or numerals to be continuously inputted to the reading of square forms of KANA. SOLUTION: When a bank name is the numeral of '62' and can not be properly read, for example, the mark of ? is displayed in a field F for the reading of square forms of KANA for the bank name. Then, an operator confirms image data G, inputs the name '62' of the bank to the field F for the reading of square forms of KANA and presses a Tab key on a keyboard. Then, the operator input '62' is converted to the reading of square forms of KANA of 'rokuju-ni'. By pressing the Tab key, the conversion program is started. Based on a conversion table, this conversion program converts the inputted numeral to the correspondent reading of square forms of KANA. Thus, since the input numeral is converted to the reading of square forms of KANA only by pressing the Tab key, it is not necessary to input the reading of square forms of KANA for the bank name manually from the keyboard.
