Title: Bpsk demodulating circuit and noncontact ic card system with the circuit
Inventor: KOBAYASHI TOMOKI
IPC: H04L27/22
Filed: 1999-04-20
Abstract: PROBLEM TO BE SOLVED: To provide the BPSK demodulating circuit which has small malfunction due to noise, etc. SOLUTION: In the BPSK demodulating circuit 56 which demodulates a BPSK-modulated binarized response signal (g) into NRZ data (e), a clock generation part 56a generates an internal clock CK1 of frequency much higher than the frequency of the binarized response signal (g). A phase switching detection part 56b synchronizes the binarized response signal (g) with an internal clock to output a synchronizing response signal and operates in synchronism with the internal clock CK1 to detect a phase shift point of the synchronizing response signal and outputs a detection pulse PhO. A flag generation part 56c performs counting operation in synchronism with the clock CK2 synchronized with the internal clock, clears the counter output once the detection pulse PhO is inputted, and sets a flag (n) when the count value reaches a predetermined value.  An output inversion part 56g presets an output (e) when the flag (h) is set and then inverts the output (e) each time the detection pulse PhO is inputted.

Title: Controller
Inventor: FUKAI YOSHIJI
IPC: G05B7/02
Filed: 1980-08-14
Abstract: PURPOSE:To switch an operation mode from AUTO to CASCADE with a simple operation by executing changeover if a fault of an external set value signal is not detected or suspending it if detected at the changeover command from an automatic operation mode to a cascade one. CONSTITUTION:A controller 1 applies operation such as PID to the deviation between a measured value PV and a set value SV to obtain operation output MV. When a mode select button C is depressed and a select command signal S2 is generated in order to switch an operation mode from automatic AUT to cascade CAS mode, a control circuit 6 turns a switch 3 to the CAS side if a falt detecting circuit 4 does not detect the fault of an external setting signal SV2, and the operation mode is transferred to CASCADE. On the contrary, when the circuit 4 detects the fault of the signal SV2, the circuit 6 suspends the changeover of the switch 3 to the CAS side to hold the automatic operation mode and displays the suspension of the operation of the operation mode changeoveron a display device 9 to inform the contents to the operator.

Title: Mobile communication packet transfer control system
Inventor: MAEDA JUNJI
IPC: H04B7/26
Filed: 1990-04-27
Abstract: PURPOSE:To efficiently execute control at the time of changing a packet transfer route by allowing an exchange or a mobile machine to store a packet respectively until the reception of the packet by the mobile machine or the exchange is completed. CONSTITUTION:At the time of receiving a packet from a mobile machine 3 or an exchange 1 to be a packet transmitting station, a base station 2a transmits the packet to the exchange 1 or the mobile machine 3 to be a packet receiving station. After receiving a receiving response signal to the signal from the packet receiving station, the station 2a transmits the receiving response signal of the packet to the packet transmitting station. Namely, the mobile machine 3 or the exchange 1 stores the packet in its resending memory until the reception of the packet is completed. Since the packet is stored in the resending memory of the transmitting source until the reception of the packet is completed at the time of transmitting/receiving the packet between the exchange 1 and the mobile machine 3, the missing of the transmitting packet or the double transmission of the packet to the transmitted destination is not generated even when a packet transfer route is changed.

Abstract: PURPOSE:To ensure an accurate detection for multipath noises, by obtaining the difference between the upper and lower side bands of an (L-R) signal contained in an FM wave detecting signal. CONSTITUTION:A multipath noise detecting circuit 12 includes a modulating circuit 13 which gives an AM modulation to the output of an FM wave detecting circuit 6 with a subcarrier signal which is taken out of a stereo demodulating circuit 7, a band pass filter 14 which makes the output of the circuit 13 pass through a prescribed frequency band and extracts the noise component contained in the prescribed frequency band, a wave detecting circuit 15 which gives an AM wave detection to the output of the filter 14, etc. Then an AM modulation is given to an FM stereo wave detecting signal with the signal obtained by multiplying a pilot signal. The multipath noise is detected in accordance with the level of the signal obtained by mixing the above-mentioned modulated signal with the FM wave detecting signal. Thus only the noise component caused by  the multipath reception which is actually heard as a noise to a reproduced sound can be detected.

Abstract: PURPOSE:To enhance noise resistance and to reduce a cost by operating a drive means by the width in pulse difference between pulse whose width changes in response to a movable body or the position of the movable body. CONSTITUTION:A designation switch 20 is operated to move a gas valve (lever) 3. Then a pulse width of an output pulse from a one-shot multivibrator 17 becomes larger than a pulse width of an output pulse from another one-shot multivibrator 14. An AND gate 24 provides an output of a pulse having a pulse width being a difference of two pulse widths. A transistor(TR) 26 is turned on by the pulse, a shape memory alloy 7 is heated and starts contracting and the lever 3 is moved in the direction of the arrow mark B. Thus, the resistance value of a potentiometer 10 is increased and the pulse width of the output pulse of the one-shot multivibrator 14 becomes large. When the width exceeds the pulse width outputted from the one-shot multivibrator 17, a pulse output from the AND gate 24 and contraction of the shape memory alloy 7 are stopped.
