Title: Burst detection circuit
Inventor: KAWASAKI TOSHIO
IPC: H03K5/08
Filed: 1987-03-20
Abstract: PURPOSE:To hold a detection time in a short time and in a constant way by changing a reference voltage being the reference of the detection in response to the input level even if the level of the burst of an input signal changes in a burst detection circuit in a system such as a TDMA system transmitting/ receiving the data in burst. CONSTITUTION:The carrier signal of an input burst is detected by diodes Dl, D2 of a detection circuit 1 and its high frequency component is eliminated by an integration device comprising a resistor R1 and a capacitor C1 and its envelope voltage is outputted. The envelope voltage output is inputted to the input terminal 21 of the differential operational amplifier of a comparator 2 as the signal input and it is compared with a reference voltage Ref given to the other input terminal 22. When the level of the input burst signal changes, the voltage of the reference voltage input is changed as shown in waveforms 22a, 22b, then the difference between the waveforms 21a and 22a is nearly equal to the difference between the waveforms 21b and 22b. Thus, the detection time tau is almost the same at any of leading/trailing of the input burst and unchanged.

Title: Ccd imager
Inventor: BURT DAVID JAMES
IPC: H04N5/376
Filed: 1998-03-17
Abstract: PROBLEM TO BE SOLVED: To multiply charges without the need for optimizing the parameter of a CCD structure or the structure. SOLUTION: Charges are stored in pixels of an image area 2 in the CCD imager 1 that represent intensity of an incident radiant ray and transferred to a storage section 3 and then transferred to an output register 4 on the basis of every row by applying a proper drive pulse to electrodes 7, 8. Signal charges in the output register 4 are transferred up to a multiplier register 5 with a drive pulse applied to charges 9, 10 to provide charge transfer in a direction denoted by the arrow. A single or pluralities of drive pulses fed to charges in the multiplier register 5 have an amplitude sufficiently high to generate a high electric field area in the register element enough to cause signal multiplication with collision by ionization. Thus, low noise amplification of the signal charges is obtained and the multiplied signal charges are detected by a charge detection circuit 6.

Title: Transmission system and transmitter thereof
Inventor: WATANABE KIMIO
IPC: H04M1/715
Filed: 1998-03-17
Abstract: PROBLEM TO BE SOLVED: To eliminate interference and to prevent the generation of noise, based on analog connection in the transmission system of an order wire or the like. SOLUTION: A switch provided for each transmission line is controlled so as to close a switch autonomously, when the flow of signals is in a different direction and open the switch, when it is in the same direction. When transmission between this transmitter A and the transmitter D is considered, since the signals in the different direction flow to the switches 56, 57, 62, 63, 58 and 59 accompanying the communication, the switches are closed. On the other hand, since the signals in the same direction flow to the switch 65, the switch is opened. As a result, between the transmission A and the transmitter D and between a transmitter E and a transmitter F, communication can be performed independently without interference. Also, by performing branching synthesis in a digital stage, the generation of the noise based on the analog connection is prevented.
