IPC: H04K1/04
Filed: 1992-07-22
Abstract: PURPOSE:To eliminate a sense of unnaturalness and a sense of incongruity due to operation delay of an expander or the like. CONSTITUTION:The output of a DET 20 used for gain control of a VCA (voltage controlled amplifier) 18 in a compressor 34 is subjected to VF conversion and is superposed on the output of a scrambler 12 and is transmitted.

Abstract: PURPOSE:To raise an automatic loading success rate in case of an open reel by varying supply reel speed at a specified position, based on a loading start position of the first time as a reference, when loading of a magnetic tape is started in the second time. CONSTITUTION:When a reel is rotated by a prescribed count portion in the forward direction, but it is detected that a tape does not reach a photoblock 12, a supply reel is stopped. Subsequently, the reel is rotated in a reverse direction, and when it is rotated until a reel count becomes a value of two times of a reel tachometer count value C1, this count value C1 slows that the length extending from a block 14 to the photoblock 12 is expressed in terms of a reel tachometer slit interval. Next, the supply reel is rotated backward by increasing its speed until it reaches a value C2 added with the count of reel tachometer required for rotating the supply reel by a semicircle portion, to 2C1, and when the tip of the tape reaches A of the opposite angle to the position of an automatic loading start, the supply reel is stopped.

Abstract: PURPOSE:To eliminate the effect of grain boundary, reduce off leakage current and stabilize the on-resistance at a low value and diminish the dispersion of the on-resistance by placing an active element in a single solid-grown crystal grain having continuous crystal structure. CONSTITUTION:At least the channel regions of a PMOS transistors 103, 104 for load resistance are stored in a single crystal grain having continuous crystal structure, and no grain boundary is contained. Accordingly, a TFT, in which off leakage currents are reduced and which are stabilized at a low resistance value at an on time and in which dispersion is diminished extending over all memory cells, can be used as the PMOS transistors 103, 104. A crystal grain required in a space occupied by the channel region must be arranged for forming the channel region of the TFT in the single crystal grain. It becomes possible, for example, by generating artificial crystal nuclei at desired spatial positions of an a-Si film, and let them grow selectively in solid phase.

Filed: 1997-07-08
Abstract: PROBLEM TO BE SOLVED: To keep a hot well water level at a desirable one where a plant is prevented from being interrupted, even when hot well water level control using an ordinary adjusting valve has a trouble. SOLUTION: A hot well water level of a condenser 2 is detected by a water level detector 8 and is inputted into a water level adjusting meter 9 as a water level detection signal. In the water level adjusting meter 9 a deviation between it and a standard water level (set value) is calculated, on the basis of which an opening instruction signal is outputted to first and second adjusting valves 10, 14. Even when the operation of the first adjusting valve 10 is troubled owing to a stick of a valve shaft, the second adjusting valve 14 functions normally, and hence the hot well water level is kept at a desirable water level.

Filed: 1995-08-01
Abstract: PROBLEM TO BE SOLVED: To stabilize the rotative speed of a burner motor to prevent hunting by a method wherein rotation instruction voltages are changed to change the rotative speed of a burner motor, and if the change amount is larger than the specified value at the time of voltage change, a rotation instruction voltage is output using a predetermined specified value. SOLUTION: A burner is of a vaporizing type, and a combustion drum 28 is connected to the front side of an air drum 27 in which a burner motor 29 is mounted. The set rotative speed of the burner motor 29 is calculated to detect the rotative pulses of the burner motor 29 and the rotative pulses are connected to calculate the actual rotative speed of the burner motor 29. Then, the difference between the set rotative speed and the actual rotative speed is compared. When the difference exceeds a neutral width, the change amount of the rotation instruction voltage is calculated to set a rotation instruction voltage. Thereby, hunting of the rotative speed of the burner motor 29 against the set rotative speed is prevented and a stable combustion at a burner 5 can be ensured.
