Title: Radio data transfer method/system
Inventor: NIWA YUJI
IPC: H04L12/28
Filed: 1997-11-21
Abstract: PROBLEM TO BE SOLVED: To reduce the cost for the reception of unnecessary mail data, to interrupt communication in accordance with the deterioration of line quality and to save the power battery resource of a radio terminal by previously transferring attribute information of digital data to a center device from a transmission terminal, recognizing the content of attribute information and directly receiving the transfer of digital data from the transmission terminal. SOLUTION: When the mail generated on a radio terminal A 101 is transmitted to a radio terminal B 103, the radio terminal A 101 transmits only a header to a mail server 102. The radio terminal B 103 receives the header from the mail server 102 and directly receives the content of the mail from the radio terminal A 101. At that time, the center device transfers only attribute information on digital data, automatically interrupts the transmission/reception of data when radio electric field intensity is unstable and resumes data transmission/ reception when radio electric field intensity becomes stable. Thus, cost for the reception of unnecessary digital data can be reduced.

Title: Optical signal reproducing device
Inventor: HORI KAZUAKI
IPC: G11B7/005
Filed: 1987-12-21
Abstract: PURPOSE:To improve S/N by controlling a current from a photodetector through a switch by a current source circuit so as to make the output voltage of a current/voltage converter equal to a reference potential and turning on the switch at the time of writing and turning off at the time of reading. CONSTITUTION:At the time of writing data, the switch 5 is turned on to divide a part of the output current ISW of the photodetector 3. The switch 5 is switched by a switch control circuit 4. At the time of reading the data, the switch 5 is turned off. This timing is synchronized with a writing pulse for passing the current to a laser diode and emitting light, thereby, the output current can be divided only at the time of writing when the output current of the photodetector 3 is large. The current DELTAIS passed by the current source 6 is controlled so as to make a current IR passing through a converted resistance Rf at the time of writing equal to the output current ISR of the photodetector 3 at the time of reading by comparing the output amplitude of the current/voltage converter 2 with the reference voltage. Therefore, at the time of writing, the current passing through the Rf is equal to the output current ISR of the detector 3 at the time of reading.

Title: Binary coding circuit for color printer
Inventor: OZAWA YOSHIO
IPC: H04N1/46
Filed: 1987-12-18
Abstract: PURPOSE:To enable predetermined colors to be stably reproduced irrespective of the conditions under which a printer is positioned or a binary coding process is applied, by setting a binary coding process at random, and printing constantly in a juxtapositional color mixture mode without generating regular patterns. CONSTITUTION:A binary coding method comprising an additional process added to a systematic dither method, and uses a 4X4 matrix having different 16 threshold values for representing 16 or 17 gradations. Different pieces of input image data are given to each of the threshold values, and individual input image data is binary coded independently. Since the gradation is determined by the number of dots in a certain area, gradation is data on fine figures contained in the image data can not be reproduced accurately. Therefore, when the binary coding process on a micro basis is set at random only for color reproduction for a large area, it is possible to print constantly in a juxtapositional color mixture mode without generating regular patterns.
