Filed: 1997-06-26
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor memory device in which the leakage defect of a bit line can be avoided with a simple circuit construction without lowering the voltage of the bit line. SOLUTION: A semiconductor memory device has bit lines and word lines which are laid vertically and horizontally, readable and writable memory cells 1, precharge MOS transistors Q1 and Q2, short-circuit MOS transistors Q3 and level setting MOS transistors Q4 and Q5. Two bit lines are provided for each bit. Three fuses F1-F3 for respective columns are connected between the precharge MOS transistors Q1 and Q2 and a bit line driving power supply terminal Vcc on their upstream side. If a leakage defect is produced in a bit line, all the fuses F1-F3 connected to that bit line are cut off. As a plurality of fuses are connected in parallel, a voltage drop between both the terminals of the fuses can be suppressed.

Title: Optical communication system
Inventor: TAKEYARI RIYOUJI
IPC: H04B10/61
Filed: 1991-07-11
Abstract: PURPOSE:To eliminate the need for phase reproduction with respect to an MSK signal with a narrow occupied band by applying delay detection to a homodyne detection output and discriminating a data from a signal resulting from adding an output of the delay detector to the original detection output. CONSTITUTION:A received signal light and a local oscillation light are inputted respectively to two ports of an optical 90 deg. hybrid 2. The signal light and the local oscillation light are both linearly polarized waves and their polarized planes are coincident with each other, and a phase difference between the signal light and the local oscillation light at the output of the hybrid 2 is 90 deg.. Then the optical power being a detection signal is equivalent to a signal resulting from detecting the signal light at an axis different by 90 deg.. The detection signal is converted into a voltage signal by an amplifier 4a and branched into two. Then the one signal is delayed by a delay line 5a and the delayed signal is multiplied with the other signal not delayed. Furthermore, the detection output is added to the product and the sum signal is filtered by a filter 6, and an identification device 7 reproduces a data. Then the amplitude is made constant independently of the fluctuation of the polarized wave and the phase reproduction is not required even for an MSK signal whose occupied band is narrow.

IPC: G11B33/10
Filed: 1984-08-17
Abstract: PURPOSE:To simplify a copying operation by detecting the rotational number of a counter roll which is revolved in response to the tape driving speed as well as the rotational number of a supply reel for slave tape and at the same time detecting the thickness of the slave tape to know an amount of the remaining tape at the supply side. CONSTITUTION:Both start and end cue signals of a master tape MT are detected by a reproduction head 21 when the 1st copying action is carried out to a slave tape ST. A CPU25 knows the recording time Lo of a program from the number of pulses given from an FG23 and records it. At the same time, the thickness of the ST is obtained from the program time and stored. Then both the MT and a drive tape DT are rewound to perform the 2nd copying job. The CPU25 calculates the wind diameter of the remaining ST from the rotational number Nc of a supply reel of the ST, the rotational number Mk of a counter roll 22 and the pulses supplied from both FG 23 and 24. Then a remaining tape amount L is calculated from the limit wind diameter of tape and the thickness of the ST. Thus the remaining copy amount is displayed on a display device 24 through the calculation of L/Lo.
