Patent JP-H0272731-A (JP)
Title: Spread spectrum communication equipment
Inventor: KAGO YOSHIYUKI
IPC: H04B1/7073
Filed: 1988-09-07
Abstract: PURPOSE:To receive a data signal satisfactorily by repeating the phase change of a spread code by using spread codes with code speed different by little so that a noise level included in a demodulation signal can be set less than a prescribed value. CONSTITUTION:The clock pulse frequency of each clock generation circuit 13 is set so that the code speed of an M series code on a transmission side can be set at 2MHz and the code speed on a reception side can be set at the one higher by 5 to 10Hz than that. A counter 142 starts a count operation when no synchronism between the M series codes on the transmission and reception sides is taken, and the phase of the M series code on the reception side is delayed sequentially by every 1/4 bit, and such operation is continued until the voltage of a noise level signal goes less than a constant voltage VA. When phase delay is stopped, the voltage of the noise level signal goes over the constant voltage VA again. Then, a phase delay operation is started again. Thus, it is possible to always maintain the synchronism between both M series codes, and to perform data communication satisfactorily.

Filed: 1997-08-22
Abstract: PROBLEM TO BE SOLVED: To prevent the ink leakage from the connecting part or the nozzle of a recording head at the time of connecting a connecting member for guiding the ink to the recording head. SOLUTION: Both side parts 31a, 31b of an ink pack 31 of an ink container are forced to the direction away from each other by a plate spring-like elastic member 32 so that the end face part 31c is tensed in a substantially flat state. When a connecting member pierces the end face part 31c for guiding an ink into a recording head, the side parts 31a, 31b are curved outward such that the volume change caused by outward swell of the side parts 31a, 31b is larger than the volume change caused by deflection of the end face part 31c derived from the external force applied on the end face part 31c along the side parts 31a, 31b. Accordingly, the negative pressure state of the ink in the ink pack 31 is strengthened by the external force.
