Title: Method and apparatus for receiving mobile communication
Inventor: ITO SADAO
IPC: H04B7/26
Filed: 1987-07-15
Abstract: PURPOSE:To prevent instantaneous interruption of communication due to channel changeover by switching a switching reception means and a switching transmission means at a speed not giving effect on communication signal and transmitting/receiving old and new channels in parallel tentatively. CONSTITUTION:When an S/N monitor section 22 of a radio system controller 20 detects it that the quality of a channel CH1 is deteriorated to be level L1 or below, a CH1 is used to give a command to a mobile radio equipment so as to start the preparation of making the transmission radio wave from the radio base station 30-2 receptible through the channel CH 2 in parallel. When the transmission wave is sent from the station 30-2 to the channel CH2, the mobile radio equipment applies the repetitive changeover. During the switching transmission/reception period applying transmission/reception of the channels CH1,CH2 in parallel, the channel CH2 itself and the quality of the said channel are confirmed, then the CH1 is opened and the communication between the station 30-2 and the mobile radio equipment is continued by the CH2 only without instantaneous interruption.

Title: Pid control method and its controller
Inventor: AKIYAMA KAZUHIDE
IPC: F16K31/06
Filed: 1998-06-24
Abstract: PROBLEM TO BE SOLVED: To execute proper and stable control by performing PID control operation after a value corresponding to a deviation between a current value detected from a controller object and a target setting value is multiplied by a PID parameter when the deviation is larger than a specified value and performing the PID control operation corresponding to the deviation when it is smaller than the specified value. SOLUTION: An operated deviation ε is compared with the specified value and it is discriminated whether the deviation ε is larger than the specified value or not (S25). When the deviation value εis larger than the specified value as a result of discrimination, a value (f) preset corresponding to a deviation (%) is multiplied by the PID parameter  P×f (P), I×f (I), D×f (D)} (S26) and after wards, the PID operation is performed corresponding to that multiplied value (S27). Control output is operated so that a current flow rate value PV can be kept at a setting flow rate value SV (S28). When the deviation ε is smaller than the specified value, on the other hand, PID control operation is performed corresponding to the deviation (S27).  Control output is operated so that the current flow rate value PV can be kept at the setting flow rate value SV (S28).
