Title: Electronic blackboard
Inventor: MIZUNO SHIGERU
IPC: H04N1/403
Filed: 1998-07-17
Abstract: PROBLEM TO BE SOLVED: To record image information written on a hand-written face with same quality at all times without being affected by a light source and a pen or the like by optionally selecting a threshold level read by a read section. SOLUTION: An operation section starts operation and applies initial setting to recording operation in response to respective modes. A switch 20 provided on a main control board is used to select a concerned threshold table among a plurality of threshold tables stored in a ROM 16 where threshold levels are differed stepwise and a threshold level in response to a density selected by a read density key is read from the threshold table selected by the switch 20 and set it to a gate array 17. After the end of the setting, recording by a printer is executed. Since a threshold level is switched optionally and selected, information is recorded with same quality at all times and the threshold level in response to the density is selected.

IPC: H04L29/08
Filed: 1998-07-17
Abstract: PROBLEM TO BE SOLVED: To provide a non-procedure transmission system where a transmission time is reduced and data are efficiently transferred. SOLUTION: A file transfer control section 30 of a non-procedure transmission terminal 3 discriminates that congestion takes place in an exchange 2, when data received by a reception section 31 indicate an error as a result of a CRC arithmetic operation and a length of the data is smaller than that to be received and allows a transmission section 32 to transmit NAK (congestion) to a line 2. Upon the receipt of the NAK (congestion) via a reception section 12, a file transfer control section 10 of a free transmission terminal 1 instructs a transmission section 11 to increase a stop bit length of data to be sent again. The transmission section 11 increases the stop bit length at the transmission of data to be retransmitted and sends the resulting bit to a line 1.

Title: Switch using photocoupler
Inventor: MIZUTA YOSHIYUKI
IPC: H03K17/78
Filed: 1981-12-17
Abstract: PURPOSE:To save electric power by using two semiconductor light emitting elements and a photocoupler connecting photodetectors consisting of diodes opposed to said elements between the gate and source of an FET in parallel. CONSTITUTION:An LED8 is opposed to a photocell group 10, and an LED7 is opposed to a photocell group 9 and a photodiode 12 which are optically insulated from the LED8 and photocell group 10. In case of using an n channel type MOS FET11 when the titled switch is to be turned on, the LED8 is turned on to generate photoelectromotive force in the photocell group 10 and positively charge the gate capacity of the MOSFET11. Since the charge of the gate capacity is not almost reduced even if the LED8 is turned off and electromotive force disappears from the photocell group 10, the switch can be driven by a pulse-like signal. When a switch is to be turned off, the LED7 is turned on to generate electromotive force in the photocell 9 and simultaneously connect the photodiode 12, so that the gate capacity is discharged. By said configuration it is unnecessary to continue to turn on the LED8.
