IPC: H04W16/24
Filed: 1981-06-01
Abstract: PURPOSE:To hold and clear a communication line surely, by appealing to ears and eyes of the subscriber of a mobile station to stop the movement of the mobile station or return to the service area when the received input electric field in the mobile station is a certain level or less in the mobile communication system. CONSTITUTION:When a mobile station 2 passes a line 3 of received input field 10dBmu and the received field becomes weak, the output potential of a comparator 12 becomes high-potential. A gate circuit 16 is turned on to output an alarm indication, and therefore, the output of a tone signal 17 is applied to a receiver sound circuit. When the mobile station runs furthermore and the received input field is lower than 0bBmu, a timer circuit 18 starts counting, and the received field is not restored to 0dBmu. When the timer circuit 18 counts a prescribed time, the output potential becomes high to break a switch circuit of a transmitter 9. Thus, the line is disconnected and is forcibly cleared, and another mobile station uses this radio frequency.

Filed: 1983-05-17
Abstract: PURPOSE:To prevent useless copying, by using an overlaid sheet conveyance detector to switch a conveyance passage to separate one sheet from the others and put the separated sheet into a place different from that for the others. CONSTITUTION:When the front edge of one of three overlaid sheets 2 of paper is detected by a sensor 21 during the conveyance of the overlaid sheets, a signal S2 is applied to a driver to operate its clutch to start rotating a roller 22b backward or clockwise. Since the rollers 22a, 22b are both rotated clockwise, only the uppermost sheet 2a of paper reaches the top of a lever 23 after the lapse of a necessary time. Because of the clockwise rotation of the roller 22b, the other lower sheets 2b, 2c are stopped on the roller and not conveyed. The level of a signal S3 is then made zero to turn the lever 23 from a position 23b to another one 23c to convey only the uppermost sheet 2a into a tray 25. When the signal S2 is returned to a level h2, the roller 22b is rotated forward or counterclockwise again to put the other lower sheets 2b, 2c into another tray 26.

The absorbance before the treatment is usually satisfactory if it is from room temp. to about 75 deg.C. The DNA and RNA are calculated from the difference in the absorbance obtd. by the measurement before and after the treatment.
