Filed: 1981-01-23
Abstract: PURPOSE:To discriminate deterioration in an underground distribution line by measuring a DC potential between a conductor of a cable to be measured buried under ground a shield layer covering it through an insulation layer with a high impedance measuring device. CONSTITUTION:A connection lead of a DC potential measuring device 5 is connected to a conductor 2 of a cable 1 to be measured and a shield layer 4 to measure a DC potential generated by deterioration of an insulation layer 3. An equivalent circuit to indicate a deterioration cable 1 is parallel circuit of an insulation resistance Rx of the cable having a deteriorated part, a cable static capacity Cx and a generated potential E which can detect fine generated voltage when the input impedance of the measuring impedance Ro is set at 10<4>MOMEGA thereby enabling discrimination of any slight state of deterioration. In practice, to avoid induction disturbance, any deteriorated part can be detected with the the input impedance of 10MOMEGA at its minimum. As for deteriorated portions in presence of water, the value of the resistance Rx can be estimated by varying the impedance Ro.

Title: Manufacture of lower electrode in dram capacitor
Inventor: SHU SHIKUN
IPC: H01L27/108
Filed: 1999-01-14
Abstract: PROBLEM TO BE SOLVED: To shorten the time required for manufacturing the lower electrode in a DRAM capacitor. SOLUTION: In this method for manufacturing the lower electrode in a DRAM capacitor, a polysilicon is vapor-deposited in place of an amorphous silicon to manufacture a lower electrode 250b. The vapor-deposition temperature of the polysilicon is higher than that for amorphous silicon, so that the vapor- deposition rate of the polysilicon becomes higher than that of amorphous silicon and its vapor-deposition time is shortened greatly. After the formation of polysilicon lower electrode, an ion group 270 is bombarded on a polysilicon layer to destroy the inner structure of the polysilicon layer, so as to change the upper part thereof into an amorphous silicon layer 252a. Finally, by forming a semispherical grain silicon 290 on the lower electrode, the surface area of the lower electrode is increased.

Filed: 1988-01-20
Abstract: PURPOSE:To prevent a reset miss due to noise generated at the time of a reset by providing a delaying circuit in the course of a feedback path. CONSTITUTION:Delaying circuits DLYs to delay differential outputs Q' and Q' level-shifted by diodes D1 and D2 of emitter followers EF1 and EF2 for outputting are provided.

Abstract: PROBLEM TO BE SOLVED: To stably display RDS(Radio Data System) data by automatically preparing a state equivalent to a state that broadcasting radio wave reception intensity is increased beyond a prescribed value in a receiver when RDS data from an RDS broadcasting station are displayed. SOLUTION: When a broadcasting radio wave from an RDS broadcasting station is at a feeble threshold level enough to display RDS data, and the RDS data display is available for the first time, an RDS judging and identifying circuit 8 in an RDS decoder 5 judges that the broadcasting radio wave is a broadcasting radio wave from the RDS broadcasting, and turns on a switching transistor Tr2 according to the output of the judged and identified output. Then, when a state equivalent to a state that the broadcasting radio wave reception intensity at an antenna 1 is increased above 3dB being a prescribed value is obtained, and the RDS data are received and displayed even once, the display is held in a display 7, and the display is stabilized by preventing the display and non-display of the RDS data from being repeated on the display 7.

Title: Parallel/serial code conversion circuit
Inventor: KAMEDA MASARU
IPC: H03M9/00
Filed: 1989-01-18
Abstract: PURPOSE:To simplify the constitution by outputting an inputted clock signal as a serial pulse code while a decimal signal is advanced stepwise in a shift register. CONSTITUTION:A signal storage means 300 stores decimal signals d1-dn corresponding to decimal numbers equal to the number of stages counted from the frontmost stage to each stage composing of a shift register 200. A switch means 400 outputs an inputted clock signal c2 as a serial pulse code (p) while the decimal signals d1-dn are advanced in the shift register 200. Since the required minimum number of stages of the shift register is enough to be equal to the maximum decimal number, the required number of stages is halved and the signal storage means stores the decimal signal outputted from a code conversion means to one stage corresponding to each shift register. Thus, the constitution is considerably simplified.

Then a signal of a printable form at the head of a recording picture in precedence over picture information is sent to a caller receiver side terminal equipment via a line interface 2. Thus, the operator of the receiver side terminal equipment easily discriminates the incoming received document and a caller received document.
