Title: Facsimile equipment
Inventor: KOTANI TAKASHI
IPC: H04M1/2745
Filed: 1991-08-29
Abstract: PURPOSE:To attain redialing without awaiting expiration of a timer by depressing a start button during redialing waiting. CONSTITUTION:Data are read by an image scanner 6 and stored in a picture data storage section 9 and a dial is entered. An address is entered by using a ten-key of an operation panel section 5 and stored in a RAM 4. Then dialing is implemented and its termination is monitored. When the dialing is not normally finished, redial wait is displayed on an LCD of the panel section 5. Then a wait flag is set to start a redial timer and to set redial standby state. The operator depresses the start button to monitor timeout of redialing and when timeout is reached, the dialing is set. When the wait flag is set, the redial timer is stopped and a destination address is read from the RAM 4 to start redialing. Thus, redialing is easily executed without awaiting time-out during redial wait.

Title: Compression system and expansion system for two-dimension image data
Inventor: NARITA YOSHINORI
IPC: H04N1/41
Filed: 1994-09-12
Abstract: PURPOSE: To attain high speed compression and expansion by detecting a same data string as a compression object partial string of a current line from data of a just preceding line and selecting, referencing and coding a table based on the number of picture elements and the position of a noted picture element so as to attain high compression processing. CONSTITUTION: A dictionary buffer 6 stores data of a just preceding line and a partial string buffer 16 extracts a compression object partial string A from a current line within a range of a maximum detection string length N. A comparator 7 detects the same data as the partial string A from data stored in the buffer 6 and in this case, let H be the number of picture elements of one line and x be the position of a noted picture element on a current line, then T=0 is set with x=0, T=0 is set with 1<=x<=H-N and T=x-H+N+1 is set with H-N+1<=x<=H-1. According to the condition above, a code generator 8 selects and references a table corresponding to each value of the T from a table group 70 and provides the output of a code depending on the position and the length of a data string on a just preceding line. Thus, the data compression rate is increased and high speed companding is attained.

Title: Gyro device
Inventor: HOJO TAKESHI
IPC: G01C19/00
Filed: 1990-09-14
Abstract: PURPOSE:To make influence of azimuth motion of a cruising body zero and obtain a highly accurate device by comparing a gyro orientation angle with an orientation angle calculated from a GPS position and then feeding it back to an integrator. CONSTITUTION:A GPS position calculation part 3 transmits a hold signal corresponding to a reception time from a satellite to a gyro orientation hold part 7. The hold part 7 holds output of an integrator 12 and then sends it to a comparator C. On the other hand, an orientation angle from an orientation calculation part 5 is compared with a gyro orientation angle at the hold part 7 by the comparator C and the remaining angle is fed back to an adder part E through a compensation calculation part 13. With this configuration, an orientation angle obtained by integrating an output angle speed of a vibration gyro 10 follows an orientation angle from the calculation part 5. Therefore, even if an output period of the calculation part 5 becomes longer, interpolation is performed with an orientation angle by the gyro 10, thus obtaining a constantly continuous and accurate orientation angle.
