Title: Sheet for character recognition and character recognition device using recording information of relevant sheet
Inventor: MISHIMA KENICHI
IPC: G06K9/20
Filed: 1988-03-30
Abstract: PURPOSE:To enable the operator of the title device to certainly recognize the erroneous transmission of a sheet for character recognition (OCR sheet) as an error by respectively printing sheet identification marks on both surface and rear of the sheet. CONSTITUTION:OCR sheet identification marks 101 and 101' are respectively printed on both surface and rear of an OCR sheet 14. The OCR sheet identification marks 101 and 101' are printed as inclination detection marks printed in the directions intersecting orthogonally with the scanning direction when, for example, the direction shown by the arrow L is the scanning direction on both surface and rear of the OCR sheet 14, but have shapes similar to those of conventional examples of inclination detection marks. Therefore, the OCR sheet can be distinguished surely from a general document. Thus character recognition can be performed certainly on the optical sheet for character recognition and, at the same time, when the sheet is overturned, the sheet can be detected immediately as an error.

Title: Communication control method
Inventor: TANIGUCHI TORU
IPC: H04L12/40
Filed: 1990-03-22
Abstract: PURPOSE:To prevent the inconveniences like confliction of a line, etc., by securing the line by returning a communication control signal to an initial state when the monitoring result of this communication control signal shows the use of the line and changing the communication control signal to line using state when the monitoring result shows the unused state of the line. CONSTITUTION:When the communication control signal is monitored and this monitor result shows the use of the line, the communication control signal is returned to the initial state. On the other hand, when the monitoring result shows the unused state of the linne, the communication control signal is changed from the line unused state to the line using state, and this state is maintained only for a circuit reservation period Tx (Tx-Tx-1< a+b). Afterwards, the communication control signal is returned from the line using state to the line unused state, and the communication control signal is monitored again. When this monitoring result shows the using state of the line, signal is returned to the initial state. On the other hand, When the monitoring result shows the unused state of the line, the communication signal is changed from the line unused state to the line using state, and the line is secured. Thus, the inconveniences like the confliction of the line, etc., is prevented even when more than two equipments secure the circuit for executing data communication in the same timing.

IPC: G06F13/00
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To suppress unnecessary charge due to a dial-up connection which is made at a constant period by performing dial-up connection control which sets a calling period for electronic mail reception confirmation by the dial-up connection with date and time information. SOLUTION: When electronic mail to this terminal is obtained from a POP (Post Office Protocol) server, self-actuation is performed by a specific-interval timer, current date and time information is obtained from a timer circuit 4, and it is decided which date and time section the date and time information is in. As the date and time section, the time zone wherein a user is working is set where the device is installed. It is checked whether or not the decided date and time section is the working time zone on a working day and mail can be obtained and when so, a dial-up connection is made to log in on the POP server, thereby receiving unprocessed mail when there is the unprocessed mail. When there is no unprocessed mail or when all unprocessed mail has been received, the user logs off from the POP server and the operation is ended.

Title: Testing method of electrostatic destruction of semiconductor element
Inventor: SATOU YOSHIHIRO
IPC: G01R31/26
Filed: 1984-04-13
Abstract: PURPOSE:To attain an electrostatic destruction test with high precision by causing electrostatic destruction while discharging electrons trapped by the oxide film of a semiconductor element. CONSTITUTION:The chip surface of the semiconductor element 1 is exposed and irradiated with light from a light source 5 and a DC voltage source 2 is set to a low voltage value; and terminals 4a and 4b of a relay 4 are connected to discharge a capacitor 3, and then terminals 4a and 4c are connected to discharge charges in the capacitor 3 to the element 1. When similar operation is repeated while the voltage value of the voltage source 2 is lowered gradually, electrons trapped in the oxide film of the element 1 during the discharging of the capacitor 3 to the element 1 are emitted with the irradiation light to eliminate a leak phenomenon, so that there is no defective mode. When the voltage value of the voltage source 2 attains to some value, the element 1 shows a defective mode such as a leak or open mode. Consequently, the accurate voltage value when the element 1 is in defective mode is obtained to evaluate the electrostatic destruction of the semiconductor element.
