Abstract: PURPOSE:To obtain a simple and inexpensive character input device, by flowing driving  currents to the first and the second conductor loop groups, which are arranged in parallel at different pitches, through m-number of switches and m-number of switches respectively, and detecting a maximum output signal with a magnetic flux detecting means. CONSTITUTION:Conductor loops l11-l14-l31-l34 and L11-L13-L41-L43 are arranged are arranged in parallel at pitches P1 and d1 respectively on an insulating plate 1, and respective conductor loops are connected to switches S1-S3 and SW1-SW4, and characters ''a'' ''shi'' are assigned to loops L11-L43. Switches are driven successively by a driving circuit 3 to flow the driving current to each conductor loop. When a conductor is touched with a pen 2 having a magnetic flux detecting coil 20, the magnetic flux due to the current flowed to the conductor loop is detected by the pen 2, and the detection output is amplified in an amplifier 4, and the signal rectified in a synchronous rectifying circuit 41 is inputted to a comparator 5 having a threshold Vfh. The comparator 5 compares the input signal with the threshold and inputs the comparison output to a microprocessor muP6. The muP6 detects a character designated by the pen 2 on a basis of the combination of switches indicating the maximum value of the output of the comparator 5.

Title: Data transmitting method
Inventor: ADACHI YASUNOBU
IPC: H04L25/49
Filed: 1993-07-23
Abstract: PURPOSE:To improve an error catching rate and to speedily detect error by checking complementariness between both data each time one piece of data and the complementary data are received. CONSTITUTION:The combination of the L level of 30mus and the H level of 90mus following it expresses '0' and the combination of the L level of 60mus and the H level of 60mus following it expresses '1'. One cycle is 120mus. In this case, when one piece of data and the complementary data are continuously transmitted, both the data are extremely adjacent in terms of time so that it can be quite rare to invert both the data and only one of them can be normally inverted when they are affected by disturbance. When either of the data or the complementary data are inverted by the disturbance, transmission error can be surely detected by checking the complementariness between both the data on the reception side since the complementariness between both the data is disordered.
