Abstract: PURPOSE:To suppress stably the suppression of relaxation oscillation and oscillated wavelength chirping by specifying the length of the 1st and 2nd fibers and feeding back the light of a digital information signal before one time slot by the feedback of its own light. CONSTITUTION:The 1st optical fiber 14 propagates the light from a light emitting element 13. The 2nd optical fiber 15 is connected to the fiber 14. The 1st and 2nd reflection films are provided respectively to one end of the fibers 14, 15. The length L1 of the fiber 14 if expressed in equation I and the length L2 of the fiber 15 is expressed in equation II, where C is the light velocity in the fibers 14, 15, fb is an information signal frequency and td is a delay time from the time of current injection of the element 13 to the light emission. Then the light before at least one time slot of the digital information signal is fed back by the feedback of its own light. Thus, the relaxation oscillation and the chirping of oscillation wavelength are suppressed stably.

Title: Video signal recording and reproducing device
Inventor: MORIOKA YOSHIHIRO
IPC: H04N5/91
Filed: 1987-10-14
Abstract: PURPOSE:To extend the recording/reproducing time by discriminating correlations of frame or field units of an input color video signal and recording time information without recording the color video signal in case of high correlations. CONSTITUTION:One-frame components of the color video signal already inputted to a one-frame memory 3 and oneframe components of the input signal are compared with each other by a comparator 2. When correlations between the input signal and the signal in the memory are high and the difference signal is smaller than a preliminarily determined threshold value as the comparison result, frame periods of high correlations are counted to update period information. When correlations are low as the comparison result, one-frame components of the signal stored in the memory are recorded on a magnetic tape. Thus, correlations of the color video signal are used without improving the performance of a tape head system at all and a still picture of high redundancy or the like is represented by, for example, the signal of one frame to reduce the recording signal.

IPC: B60L3/08
Filed: 1990-09-27
Abstract: PURPOSE:To prevent runaway of a motor car, provided with a control means for detecting the traveling speed and running the motor car with a speed designated by a designating means, by limiting the maximum speed thereof based on a speed detected on a down slope through the designating means. CONSTITUTION:When a key switch (not shown) in a motor car is turned ON and an accelerator lever is pushed down, a variable resistor 16 in a direction/ speed designating circuit 15 functions to provides a signal to a CPU 17. The CPU 17 outputs a speed signal corresponding to a drive signal and the resistance of the variable resistor 16 and rotates a motor 7 forward through a drive/reverse switching circuit 20. A rotational speed detector 21 comprising a photocoupler 22 determines the rotational speed of the motor 7 which is then fed to the CPU 17. If a rotational speed detected on a down slope is higher that a value set in a speed limit circuit 24 and that state endures longer than a predetermined time (about 0.5sec) the CPU 17 energizes a generator brake circuit 25 to lower the speed. According to the constitution, danger due to runaway on a down slope can be prevented automatically.

IPC: H02J1/10
Filed: 1989-10-03
Abstract: PURPOSE:To obtain a controller for controlling more I/O signals with low cost by integrating a power supply for an operating unit and power supply for an I/O unit into one unit and inserting a voltage compensator compensating for the voltage drop across of a source coupled diode in series with said diode. CONSTITUTION:Power supplies 3, 13 arranged in controllers 10, 20 feed power to operating units 4, 14 and further feed power through voltage compensators 5, 15 and diodes 2, 12 to an I/O unit 30. The voltage compensators 5, 15 add the voltage drop 0.7V across the diodes 2, 12 to the output voltage 5V from the power supplies 3, 13 and produce the sum voltage. The voltage compensators 5, 15 incorporate DC-DC converters generating 0.7V which compensates for the 0.7V voltage drop across the diode, and supply 5V rating voltage to the I/O unit 30. Since the DC-DC converter is only required to output 0.7V, the capacity of power supply can be reduced to 12% of conventional power supply requiring 5.7V.

Filed: 1990-09-27
Abstract: PURPOSE:To enable the reuse of an electronic cash register after initialization by clearing a memory and executing initialization after printing the added value of sales information to be stored in the memory by a printer means. CONSTITUTION:When the runaway of a processing means 1 happens and an operator instructs the initialization with the operation of a initialization key 3 provided in an input means 2, the added value of the sales information to be stored in memories 6 and 7 is printed on recording paper 9 and then the memories 6 and 7 are cleared for initialization.

Title: Semiconductor optical device and optical network using the same
Inventor: UCHIDA MAMORU
IPC: H04B10/278
Filed: 1996-09-09
Abstract: PROBLEM TO BE SOLVED: To restrain chirping by adjusting phases of the respective lights to be guided to optical waveguides in a Fabry-Perot resonator region and a distributed feedback type resonator (DFB) region. SOLUTION: The phase of a light which is outputted from a region 1 (distributed feedback type semiconductor laser), reflected by a region 3, and returned to the region 1 is adjusted by changing the refractive index of the region 2. When the light of the distributed feedback type semiconductor laser is intensive, the region 3 constituting a Fabry-Perot laser amplifies the light of DFB mode and consumes the gain, so that the oscillation is restrained. When the light of the DFB mode becomes weak, the consumption of gain in the region 3 decreases, and the gain is given to the Fabry-Perot mode. When pumping is sufficient, oscillation of Fabry-Perot mode is generated. By controlling the carrier injection amount to the respective regions, the threshold gains of both modes can be made equal, and further the switching of stable TM mode and TE mode of multimode is enabled.

Abstract: PURPOSE:To form aluminum wirings without adverse influence to the formation of a layer on an aluminum wiring pattern by forming an Si3N4 film and a polysilicon film on a substrate. CONSTITUTION:An Si3N4 film 2 and a polysilicon film 3 are deposited on the entire substrate 1 by a plasma CVD method, an aluminum film 4 is deposited thereon, a resist 5 is then coated. The resist 5 is then exposed in a predetermined pattern, developed to obtain a hole 5a, and the film 4 is etched by RIE. The aluminum 4a remains in the step in the just etched state. When it is further overetched, the remainder 3a of the polysilicon film exists. Since the interlayer film is polysilicon and Si3N4 at this time, no oxygen for causing the sidewall protecting film of the aluminum film to be damaged is supplied from anywhere, the reaction seed of etching is reacted with the polysilicon to eliminate an inverted taper due to the etching of the lower portion of the pattern of the aluminum film.
