Title: Ofdm transmitter and ofdm receiver
Inventor: ISHIKAWA TATSUYA
IPC: H04L27/18
Filed: 1993-11-16
Abstract: PURPOSE:To prevent the influence from another communication by suppressing the peak of an OFDM(orthogonal frequency division multiplex) wave to be modulated and to make the dynamic range of a circuit small. CONSTITUTION:An OFDM transmitter 55 performs an amplitude limit of the OFDH wave to be modulated from a reverse FET circuit 8 by a limitter 48. Thus, the adverse influence onto another communication in a transmission line can be prevented. In an OFDM receiver 56, the envelopes that A/D converters 33 and 34 output are detected by an envelope detection circuit 50 and a disappearing decision circuit 51 decides a modulation symbol having a peak from the comparision with a prescribed ampltitude level. In an error correction decoding circuit 49, this decision result is imparted and a diappearing error correction is performed for the demodulation symbol of the modulation symbol having the peak. Even when the dynamic ranges of the A/D converters 33 and 34 are made small, the demodulation symbol of the modulation symbol having the peak can be reproduced without a mistake.

Abstract: PROBLEM TO BE SOLVED: To provide the video tape recorder incorporating a frame switcher for two inputs at low cost. SOLUTION: Two camera input video signals inputted in synchronization with each other from camera input terminals 20a and 20b are alternately changed in a changeover switch 22 by an RF switching pulse.

Abstract: PURPOSE:To facilitate correction of electrical off-set and mechanical off-set (inclination) in carrying control by providing signals for correcting both of electrical off-set and mechanical off-set to an independent corrective drive circuit connected with a differential amplifier or a motor. CONSTITUTION:An electrical off-set voltage Vo obtained from a first memory M1 is subjected to polarity inversion through a next stage polarity inversion circuit 14 to produce a value -Vo which is fed to a second adder 17. The electrical off-set voltage -Vo is added to a mechanical off-set voltage -Vc, in the second adder 17, to produce an output -Vc-Vo, which is then converted into an analog correcting signal through a D/A converter 18. In normal operation, a first switch SW1 is connected with a terminal D and a second switch SW2 is made at a contact (d) thus performing ON control of a third switch SW3. By such arrangement, the correcting voltage -Vc-Vo is added to a DC voltage corresponding to a tracking error TE and fed to the differential amplifier 10.

Title: Transmission timing synchronizing method using absolute time
Inventor: KORI TAKEJI
IPC: H04L7/00
Filed: 1990-10-26
Abstract: PURPOSE:To keep the timing between radio base stations constant without provision of a control line for timing synchronization by sending a signal based on a time of a clock ticking in an absolute time in its own station at each reference station. CONSTITUTION:Each radio base station 34 make a request of absolute time information to a reference time station 32 periodically. The reference time station 32 sends back an absolute time on request against the request from each radio base station 34 as absolute time information 37 via a subscriber line 33 and a network. Then each radio base station 34 based on the received absolute time information 37 adjusts the time of a lock clock 35 of its own station so as to be an absolute time. Moreover, each radio base station 34 decides a timing of a transmission signal based on the clock of the local clock 35 of its own station and sends the signal and the timing of lie control is matched similarly based on the time of the local clock 35. Thus, the signal transmission timing and a control timing between the radio base stations 34 are matched in an accurate timing without provision of an exclusive line for adjusting timing.

Filed: 1989-11-07
Abstract: PURPOSE: To save power consumption by switching a mode to a standby mode after switching power supply to a control comparator to dischage to a capacitor or to charge and switching the mode to an operation mode before switching to charge or discharge. CONSTITUTION: When the capacitance voltage of a node 20 exceeds reference voltage Vret , a flip flop(FF) 30 is set up by a comparator 22 and a transistor(TR) 18 is turned to a conductive state, so that the voltage of the node 20 is reduced. Then the comparator 22 supplies a low level signal to the set input terminal of the FF 30. Output voltage from the FF 30 is supplied to a comparator 32 through a delay element 34 and the comparator 32 suplies a high level signal to the reset input terminal of the FF 30 after the lapse of prescribed delay time. Then the FF 30 is reset and the TR 18 is turned off by the low level output signal from the FF 30. Since the comparators 22, 32 consumes power only at the switching moment of the TR 18, power consumption can be reduced.

Title: Constant velocity joint
Inventor: NAGAOKA ATSUSHI
IPC: F16D3/20
Filed: 1995-11-07
Abstract: PROBLEM TO BE SOLVED: To secure a constant velocity joint that is able to improve the extent of plunge performance by reducing an inclined variable of a roller rolling on a track groove. SOLUTION: When a drive shaft is rotated, the torque is transmitted to an inner member 25 via an outer cup 22, and thereby a driven shaft 24 rotates via a spider shaft 38a. In the case where a roller outer 28 is tilted to some extent, an upper side end 60 of a holder 42 is not brought into contact with a plane part 34 of a track groove 26a, but a guide washer 46 is made in contact with this plane part 34, thereby regulating its tilt angle. Therefore, a tilt angle of the roller outer 28 comes to B, whereby this tilt angle of the roller outer 28 can be made smaller as comapred with the conventional technical knowledge. In consequence, any sliding friction to be produced with the inclination of the roller outer 28 is reduced, and thus an improvement in the extent of plunge performance to be transferred to the driven shaft 24 is well promotable.
