Title: Ofdm transmitter-receiver and method therefor
Inventor: OTA GENICHIRO
IPC: H04J11/00
Filed: 1998-11-06
Abstract: PROBLEM TO BE SOLVED: To utilize the same frequency band for plural kinds of radio communications different in modulation system and to take precedence of communication of a public system with high publicity over others in the case of using the frequency band. SOLUTION: A base station adopting the orthogonal frequency division multiplex OFDM system for public system communication applies differential coding to an access channel including a frame synchronizing signal, uses only a specific subcarrier to make transmission. A base station of a non-public system employing a single carrier system (b) receives the access channel to apply differential detection processing thereto, takes synchronization with the public system base station, the public system base station assigns an idle slot to the non-public system base station and the non-public system base station uses the assigned slot to conduct radio communication (d). Furthermore, in order to take precedence of public system communication over others, the public system base station optionally changes number of slots assigned to the non-public system.

Filed: 1990-11-26
Abstract: PURPOSE:To find the causes of troubles quickly and alleviate the burden on the operator by detecting the state of contact points due to malfunction of auxiliary switches and the malfunction of switches for actuating motors by means of a display circuit. CONSTITUTION:When a malfunction occurs in which a closing coil 2 does not work with a switch 1 turned on, a circuit of a resistor 17, a light emitting diode(LED) 26, and a resistor 18 is formed and the LED lights up to detect the malfunction of a switching switch 14. When the switch 1 is closed under the condition of a trouble of an auxiliary switch 3 being open, a charging current flows through a resistor 10 and a condenser 11 to turn a transistor 4 on, the base current of the transistor 4 decreases after a constant time, and a direct current voltage is produced between the emitter and collector of the transistor 4. Due to that voltage, a circuit of a resistor 25, and an LED 24 is formed to light up the LED 24. This makes quick locating of troubles possible to alleviate the burden on operators.

Filed: 1990-11-26
Abstract: PURPOSE:To prevent a customer from waiting by complementing paper money parallelly with a transaction processing in a time zone not to exert an influence upon the transaction processing. CONSTITUTION:In the case of a payment transaction, a paper money complement operatable time zone 36 is determined from a point of time 39 when one transaction is finished, to a dispensing paper money counting operation starting time 40 for the next transaction and a paper money complementing operation is executed parallelly with customer input operation time 30 for the next transaction and center communication time 30-33. In the case of a reception transaction, the note complement operatable time zone 36 is determined form the point of time 39, when one transaction is finished, to a receiving paper money counting operation starting point of time 41 for the next transaction and the paper money complementing operation is executed parallelly with the input operation time 30 until it is completed to put in paper moneys for the next transaction. Thus, since the customer transaction is preferentially received and the transaction processing to a prescribed step is parallelly executed with the paper money complementing operation, customer waiting time can be shortened.

Title: Automatic bias device
Inventor: KOBAYASHI YUICHI
IPC: G03G21/00
Filed: 1988-12-16
Abstract: PURPOSE:To preclude the development effect of a sensor by interposing a diode on the input side of a detecting circuit for the potential of a photosensitive body in the opposite direction from the direction of a current. CONSTITUTION:A potential induced at the sensor 14 is inputted to the gate of a field effect transistor(TR) 22 through the diode 34 connected in the opposite direction from the direction of the current and detected by the detecting circuit 17 because the input resistance of the TR 22 is extremely large. When the induced voltage of the sensor 14 becomes higher than the source voltage of the detecting circuit 17, the potential on the gate side of the TR 22 does not rise above the source voltage of the circuit 17, but the induced voltage of the sensor 14 is cut off by a diode 34 (exactly speaking, part of the current flows to the TR 22 as a leak current), so that the voltage follows up the surface potential of the photosensitive drum 11 without being affected by the source voltage of the circuit 17. Therefore, the sensor 14 has no development effect.

Abstract: PURPOSE:To prevent the occurrence of a delay in the process of a job by individually performing the storage of key data by every kind of jobs and sending of key data by jobs based on the kind of jobs informed from a command control section. CONSTITUTION:The storage of key data in a key data storing section 33 is individually performed by every kind of jobs and, at the same time, the sending of the key data to a command control section 34 from the section 33 is performed by jobs based on the kind of jobs informed from the section 34.

Title: Radar equipment
Inventor: INATSUNE SHIGEO
IPC: G01S7/292
Filed: 1990-11-22
Abstract: PURPOSE:To prevent range bin movement even for a target signal shifted by the Doppler effect and prevent decay of amplitude by giving reference signal used for pulse compression after compensating in accordance with the target Doppler frequency obtained from the result of coherence integration. CONSTITUTION:The output of an amplitude detector 20 is input to a threshold detector 21 and if it exceeds a determined threshold, it is judged to be a target. A frequency change rate alpha and a pre-compression pulse width tau are given by a chirp signal generator 12 and a Doppler frequency fd is obtained from the output of the amplitude detector 20. The recalculation of the reference signal is executed by a reference signal calculation means 101. Since the pulse compression is done with the use of the recalculated reference signal for the coherent integration after the second time, the signal after the pulse compression never have a range bin movement. Also for the amplitude width, decay due to Doppler frequency is never caused.

Filed: 1992-11-04
Abstract: PURPOSE:To rapidly reproduce a signal even when a synchronizing signal is discontinuous by opening a gate circuit when a gap area is deteceted and taking out the synchronizing signal immediately after that. CONSTITUTION:A synchronizing circuit block 1 is provided at every track, and a clock reproducing circuit 2 detects by a reproducing head, and a bit clock is reproduced from a digital signal and outputted. A clock obtained from the circuit 2 is used as the input clock of a synchronizing pattern detection circuit 3, and the circuit 3 outputs when a prescribed synchronizing signal pattern is detected from the regenerative digital signal. At this time, when a discontinuous part exists in the synchronizing signal and a dropout exists in the track, it is judged that no synchronizing pattern is detected by a synchronism detection judgment circuit 6. Then, a counter 7 starts to count and when the count value is arrived at a prescribed value, an FF8 is set, and the gate circuit 4 is opened by a gate signal G3. Thus, only the output corresponding to the actual synchronizing signal in the output of the circuit 3 is extracted and reproduced rapidly.
