Title: Key distributing method using quantum cipher
Inventor: NANBU YOSHIHIRO
IPC: H04B10/70
Filed: 1999-05-12
Abstract: PROBLEM TO BE SOLVED: To obtain a four-state cipher which is superior in safety and transmission rate by encoding random bit data, used as a key, into light pulse trains, mixing a light pulse train in a multiplexed state of their coherent states with a time series of light pulses and transmitting them, and checking the interference state of light pulses. SOLUTION: A sender 1 and a receiver 2 uses a quantum channel 5 and an open channel 6. The quantum channel 5 is formed of an optical fiber which sends a time series of coherent light pulses 3 carrying 1-bit information as a key to be shared or multiplexed-state light pulses for wiretap detection. The open channel 6 confirms the transmission and reception states. A coherent light source 7 is a light source used to distribute a common bit random number series as a key and a semiconductor laser light source is used. A coherent light source 8 is a light source composed of a semiconductor laser used to generate the multiplexed light state for wiretap detection.

Title: Facsimile equipment
Inventor: SATO KENICHIRO
IPC: H04N1/00
Filed: 1989-05-25
Abstract: PURPOSE:To modify the impression of a transmission original and to improve the appealing power to the remote side by using a storage control means which stores the general-purpose picture data in a memory and a transmission control means which sends the storage contents of the memory together with the transmission original at transmission. CONSTITUTION:When an original 1 is transmitted, a register button 3 and an additional button 4 are operated at an operation part 14. Thus a picture stored in a memory 15 is synthesized with the picture of the transmission original and transmitted. For instance, an original 5 containing a company logogram is stored in the memory 15 with operation of the button 3. Then the original 1 is transmitted after the push of the button 4. Thus the company logogram is outputted to an output paper 6 of the receiver side as shown in a diagram. In such a way, the company logogram can be added to another original with use of the information stored in the memory 15. As a result, the impression of the transmission original is modified, and the appealing power is improved to the remote side.

Filed: 1987-05-28
Abstract: PURPOSE:To obtain an input device excellent in operability in a simple constitution by using a means which controls the indicating frequency of each menu item for each menu group. CONSTITUTION:A control means 102 decides an instruction given from a mouse 101. When the change of a display menu is decided, the means 102 selects a desired menu group out of a memory means 105 and displays it. At the same time, a frequency deciding means 108 decides a menu item having the highest instruction frequency out of the instruction frequency information that is read out concurrently with said displayed menu group and delivers display position information on the decided menu item. Then a cursor showing the position of the mouse 101 is moved and displayed at a position indicated by the means 102. When an item is selected out of the displayed menu group by the mouse 101, the frequency information on the read-out menu group is replaced with a frequency control means 109 and written into the means 105. In a menu selection mode the cursor is displayed on the menu item having the highest indication frequency despite no shift of the mouse 101. Thus the useless shift of the mouse 101 is evaded and the operability is improved with an input device.
