Title: Magnetic tape unit
Inventor: KAJINO JIROU
IPC: G11B15/665
Filed: 1979-06-13
Abstract: PURPOSE:To increase the accuracy of stop position of the magnetic tape drawing out means and to smooth the unloading of magnetic tape, by driving the magnetic tape unloading means of magnetic tape unit without being effected to the position of rotation stop of motor. CONSTITUTION:The revolution of the motor 70 of the magnetic tape unit is delivered to the cam 72 via the belt 66 and the gear 68. Further, when the rotary  angle of the cam 72 reaches 360 deg.C, the guide posts 20, 24 and 28, 30 move to specific position, and the tape unloading end switch is OFF to interrupt the power  supply to the motor 70. In this case, the stop position of the guide posts 20, 24 and  28, 30 is restricted at the stoppers 25, 29 independently of the amount of overrun of  the motor 70. Since the Bestehorn curve is used for the lift curve of the cam 72, the speed and acceleration of the sector type gear 78 is zero at halt, allowing to unload the magnetic tape smoothly.

Title: Facsimile transmission system
Inventor: KAWADE TAKASHI
IPC: H04N1/21
Filed: 1979-06-14
Abstract: PURPOSE:To avoid the speed reduction as well as increase the using efficiency of the circuit, by securing the continuation of transmission without transmitting again the original from the beginning in case the writing action of the picture signal is delayed with transmission of the immediately preceding 1-line signal. CONSTITUTION:The picture signals are read with every line out of storing memory 1 under the control of control circuit 7, and then written into idle line memory 3 or 4 via selection circuit 2. The alternating writing and reading are given to memory 3 or 4 at the normal time. But in case the writing to one memory in unfinished although the reading is finished for the other memory because of the delay of the process time for memory 1 and other factors, circuit 7 gives no switching between selection circuits 2 and 5 but reads again directly the contents equivalent to one line out immediately before to give the control for transmission of the contents to modulator 6. As a result, the signals to be sent to the receiver via communication circuit 9 become identical between the two lines. And the screen impairment is not visible with no retransmission after some interruption. Thus the speed reduction can be avoided for transmission.

Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To prevent crosstalk in a base station by limiting call transmission by a plurality of slave stations in a radio communication system consisting of the one base station and a plurality of the slave stations. SOLUTION: Prior to transmission of voice data from a slave station side to a base station, a control frame signal is sent/received between both the stations first to set up communication connection. Then a control frame signal generating section 15 of the slave station side generates a control frame signal including own station number data and data to obtain permission of transmission start, and an antenna 19 transmits the signal to the base station. The base station receives this transmission signal, and a data discrimination section 44 discriminates transmission contents. After the discrimination, a control frame signal generating section 35 of the base station generates the control frame signal including data denoting transmission permission and the station number data of the slave station and transmits the control signal to the slave station. A data discrimination section 24 of the slave station discriminates transmission contents and confirms the station number data and the transmission permission. The slave station transmits voice data after the step above.

Abstract: PURPOSE:To reduce the operating capacity and to enable high speed operation, by calculating the noise level through the use of each vodeo element information at the end of scanning line and each video element information at the beginning end of the next scanning line. CONSTITUTION:The noise level of original background paper is calculated at the adders 7, 9 and the divider 8, by using a plurality of contrast level information corresponding to each video element obtained at each read-in and scanning of the end M and the beginning M' of each scanning line. This noise level is taken as threshold level and fed to the comparator 15 to reject the noise on background paper. Accordingly, since the operating element is less, the processing speed is increased and since the optimum threshold level can always be set according to the change in the contrast level of the original background paper, the reproduced picture with high quality can be obtained.

Inventor: OONO MAKOTO
IPC: H02M3/155
Filed: 1981-05-19
Abstract: PURPOSE:To lower the cost, by realizing the prevention of the destruction of a high frequency voltage rectifying diode, which is realized conventionally only by a reactor having the rectangular B-H characteristic, due to the limitation of the reverse current of the diode by a reactor using a ferrite core. CONSTITUTION:An ordinary ferrite core is used as the core of a reactor 16 because the reactor 16 is excited in DC by a winding n2 to reduce the hysteresis loss considerably. The spike-shaped voltage of a winding n1 due to a winding n2 is absorbed by a resistance 17 and a capacitor 18. A current IF of a diode 15 and an applied voltage VF are shown in figures. The current of the winding n1 is equal to that of the diode 15 approximately. Consequently, the current IF shown in figure is considered to be flowed to the winding n1. However, when the current is flowed to the winding n2 with the polarity shown in figure, the internal magnetic field is changed by components corresponding to this current, and the hysteresis loss is reduced considerably.
