Filed: 1984-03-14
Abstract: PURPOSE:To change communication channels only through simple operation by generating a channel change command according to the manual operation, calling and changing the channel number of a control signal into the number of a call channel and sending a control signal, and then performing origination to the call channel. CONSTITUTION:When a channel change command button is operated at a station while stations A and B have communication over a speech channel 40CH, a controller 4 changes the channel number of a control signal from the 40th channel to the 1st channel of a call channel in response to the operation and sends its control signal from a transmission part 6. At this time, the transmission channel of the transmission part 6 is the 40th channel. The controller 4 of the station B places the 1st channel in a reception stand-by state when the group number of a receive control signal coincides with a set number according to the control signal and the channel of the receive control signal is the 1st channel during communication with the station A. The controller 4 of the station A generates a control signal of the 1st channel and then changes a transmission/reception channel from a speech channel to a call channel to perform originating operation.

Title: Method for detecting current
Inventor: KATSUYAMA TERUSHI
IPC: G01R15/18
Filed: 1990-03-01
Abstract: PURPOSE:To obtain a small-sized current detector for both of AC and DC by using one iron core having rectangular hysteresis characteristics to subject the same to AC excitation and suddenly changing the magnetic flux density of the iron core by a current to be detected and detecting a current from the change of the magnetic flux density. CONSTITUTION:One iron core having rectangular histeresis characteristics is used to allow a constant current to flow to an exciting coil 16 to subject the iron core 15 to AC excitation. The magnetic flux density range of the iron core 15 generated by the current to be detected flowing to a conductor 18 is suddenly changed along the gradient of the magnetic hysteresis curve of the iron core 15 and this change is taken out by a separately provided detection coil 17. The induced voltage of the detection coil 17 is amplified by an amplifier 21 and, when the amplified voltage is allowed to pass through a both-wave rectifier 22 and a peak hold device 23, the DC voltage proportional to the max. value of the induced voltage is obtained. By this method, since one iron core 15 is used, this current detector can be made small-sized and receives no effect of an external magnetic field.

IPC: H04N5/369
Filed: 1988-03-03
Abstract: PURPOSE:To reduce smear by splitting an image pickup signal into plural number of times and transferring the signal in the lump for each split block.

Filed: 1985-03-13
Abstract: PURPOSE:To obtain a stably phase locked signal with high accuracy and to reduce remarkably the scale of a delay circuit by setting a delay time circulating a phase locked loop within a prescribed range using a period of a reference signal. CONSTITUTION:A fixed oscillator 20 is operated in a frequency being an integral number (N) times of a frequency fi of the reference signal Si and sends its output to a delay circuit 21. The circuit 21 generates m-set of signals having a prescribed phase difference to input them to a phase switching circuit 15, a data selector 14 of the circuit 15 selects sequentially one signal in response to the phase of the signal Si among the m-set of signals and inputs the signal to a frequency divider 23 having 1/n frequency division. The frequency divider 23 inputs the signal So subject to 1/n into a phase comparator 11. The comparator 11 inputs a phase difference signal between the signals Si and So to a control pulse generating circuit 12, which inputs the output pulse to an up/down counter 13 of the circuit 15 to form a phase locked loop. The delay time (t) circulating through the phase locked loop is set to be in the relation expressed in equation I by using a period T of the signal Si. Thus, a stable phase locked signal with high accuracy is obtained.

Title: Message output method
Inventor: SEKINE HIROTAKA
IPC: G06F3/048
Filed: 1992-03-09
Abstract: PURPOSE:To improve the operability and the service performance for output of messages. CONSTITUTION:A selected message is set to a message selector of an internal area (step 1), and the type of the message to be outputted is discriminated based on the data on the selector (step 2). The discriminated message is taken out of a message storing area where the messages are previously stored in accordance with each type (step 3). Then the taken-out message is outputted (step 4). When the output of the message is complete, a waiting state is kept for a period of time decided previously based on the type and the relative difficulty of the message (step 5). When the waiting state is over, the value of the message selector is set based on the algorithm decided previously according to the message (step 6). Then the step 2 is carried out again. If an input request is received (step 7), an interruption is applied to the step 2 (step 8). Thus the message output processing is complete and the next processing is started.

Title: Access channel arranging method
Inventor: ITO MASAHIKO
IPC: H04W56/00
Filed: 1997-03-05
Abstract: PROBLEM TO BE SOLVED: To reduce interference by receiving the request of communication from a terminal station in whole directions so as to execute communication through the use of a sector antenna and permitting an access channel to shift timing with the other radio base station. SOLUTION: Communication is executed between the radio base station and a radio terminal with a specified directional antenna at the same frequency and time. Since a control channel and a user channel spatially differ when the direction of the directional antenna differs even if the frequency and timing, which are equal to those of the other adjacent radio base station, are used, interference does not occur. The control channel and the user channel can effectively be used. Since the access channel transmits data in the whole directions by using all the sector antennas, sector effect cannot be expected. Thus, is hourly executed between the radio base stations while the frequencies similar to those of the control channel and user channel are used. Consequently, the access channel without interference can be set.
