Simultaneously, as for an output for detecting the background in an area where there is no character, when there is no background concentrically such as a two-dimensional information operation processing which uses, for instance, a white picture element of 2 X 2 as a decision unit, a processing for deciding that there is no background is executed, and in an area where there is a character, one piece of white picture element becomes a decision unit for whether the background exists or not. In such a manner, the background of a character and a line drawing can be detected.

Title: Driver for electrostatic type display device
Inventor: HATA KAZUO
IPC: G09G3/34
Filed: 1987-12-07
Abstract: PURPOSE: To remarkably reduce power consumption by providing an on/off means intermittently turning on/off a power source for applying voltage by means of a voltage applying circuit. CONSTITUTION: To take a display unit 10a as an example among many displaying units, when a thylister SCR is turned on/off according to the presence/absence of the gate signal G1 of the thylister SCR, red, e.g. is displayed when a movable electrode 5a is brought into contact with an external fixed electrode 4a and white, e.g. is displayed when the movable electrode 5a is brought into contact with an internal fixed electrode 3a. In this case, a driving AC power source 1 itself is turned on/off to reduce the ratio of on period/(on period + off periof) to remarkably reduce power consumption.  Even at the time of reducing power consumption of turning on/off like this, the movable electrode temperarily operated at the time of turning on is not recovered from the operated state soon even at the time of off, the power source is turned on again before long and the movable electrode is turned into an operated state. Thus, the movable electrode can keep the operated state in spite of turning on/off the power source.

IPC: E04H15/22
Filed: 1989-11-29
Abstract: PURPOSE:To previously prevent an unstable vibration of a roof due to disturbances by fixing a tube containing compressed air along a cable when the roof face made of a membrane reinforced with the cable is under a deflated condition. CONSTITUTION:When a roof face 5 equipped with a membrane 2 on cables 1 fixed at the side wall 6 of an air membrane structure at the edges thereof is under a deflated condition, tubes 4 are fixed along the lower face of the cables 1 every appropriate distance. Next, compressed air is charged in the tubes 4 to make them rigid and also the cables 1 are reinforced to increase the bending rigidity. In this way, vibration generated in almost unstable conditions of the cable 1 due to disturbances like wind pressure during construction and deflation is prevented. Thereby, breakage of the cables and anchoring parts is avoidable.

Filed: 1989-11-29
Abstract: PURPOSE:To improve the accuracy of radioactive contamination detection sensitivity by providing a 1st detector which detects a body to be measured being carried in and a 2nd detector which detects the measured body being carried out. CONSTITUTION:An upstream-side photoelectric switch 7 detects the body to be measured which is conveyed between a light emitting element 7A and a light receiving element 7B.

Title: Ground-fault protective circuit
Inventor: SOEDA HIDEAKI
IPC: H02J3/04
Filed: 1993-11-12
Abstract: PURPOSE:To surely detect a ground fault so as to minimize the power failure caused by the fault by connecting in series first and second ground-fault detectors, with the detecting winding of one detector being wound in the opposite direction against that of the other detector, and connecting in parallel a switch to one winding of a ground-fault connecting device connected to the end of the serially connected windings. CONSTITUTION:In case a ground fault occurs when two buses 1 and 5 are operated in parallel through the circuit breaker 10 of a bus connecting line 9, the buses 1 and 5 are switched to individual operations by opening the circuit breaker 10. Then whether the ground fault occurs at the first bus 1 or second bus 5 is detected from the operating state of each ground-fault relay 21 connected to each ground-fault detector 19 and 20 by opening/closing switches 24 and 25 connected in parallel with the detecting windings of the detectors 19 and 20 and the circuit breaker 3 (7) of the first bus 1 (5) where the ground- fault occurs is opened. Therefore, the occurrence of a ground fault can be surely detected and the extent of the power failure caused by the fault can be minimized.

Title: Method for suppressing and controlling torsional vibration of motor
Inventor: SHIBATA NAOTAKE
IPC: H02P25/098
Filed: 1994-12-12
Abstract: PURPOSE: To provide a method by which the torsional vibration of a motor can be suppressed well even at a higher resonance frequency. CONSTITUTION: A motor speed control system provided with a mechanism which transmits the drive torque of a motor to a load through a drive shaft having a torsion spring system controls the torque of the motor by using a signal TRFM obtained by adding a motor load torque estimating signal TRFL calculated form the output signal TRFA of a speed controller 11 and a speed signal detected from the motor to the output signal of the speed controller 11 as a new torque command. Therefore, the amplitude of the vibration of the motor can be prevented from becoming larger by offsetting the load torque of the motor and, at the same time, a damping element is generated in a vibrating system by controlling the speed of the motor by using a signal obtained by subtracting a damping control signal calculated from the signal TRFL from a motor speed command signal as a new speed command signal.  In addition, the torsional vibration of the drive shaft generated when the motor is accelerated or decelerated or the load abruptly changes can be suppressed and the load responding characteristic of the motor can be improved.

Filed: 1997-10-22
Abstract: PROBLEM TO BE SOLVED: To prevent flowing-down to a lower section from the mountain side of soil and sand on a ground surface of the face of a slope, to which a method of slope stabilization construction is executed. SOLUTION: Bearing-pressure members 1 are installed at the upper end sections of a plurality of anchor rods 5 driven to the face of a slope 8a at intervals respectively, nuts 7 are clamped and tensile force is applied to the anchor rods 5, and the tensile force is transmitted to the face of the slope through the bearing-pressure members 1 and the face of the slope is stabilized. Beltlike netted members 10 are stretched at right angles with the face of the slope among the two bearing-pressure members 1 arranged in the horizontal direction. Even when soil and sand on a ground surface intend to flow down from the mountain side to a lower section owing to the inclination of the face of the slope 8a, the netted members 10 stop soil and sand.  Not only a slope ground is stabilized by a bearing-pressure effect by the bearing-pressure members 1 but also the flowing-down of soil and sand on the ground surface can be prevented.

Title: Nickel-zinc-based ferrite
Inventor: ISHIKAWA KATSUHISA
IPC: H01F1/34
Filed: 1996-11-20
Abstract: PROBLEM TO BE SOLVED: To obtain a ferrite having a low dielectric loss and a high saturation magnetization by mixing powders in a composition within a specific range based on a compositional formula represented by the formula and baking the resultant mixture. SOLUTION: This ferrite is an Ni-Zn-based ferrite obtained by mixing powders and baking the resultant mixture within the ranges of 0.55<=X<=0.80, 0.001<=Y<=0.20 and 0.001<=Z<=0.04. The reason why the limitation is made on the ranges is as follows: The saturation magnetization is reduced and the dielectric loss is increased even when the composition X is below 0.55 or above 0.80. The dielectric loss is increased when the manganese composition Y is below 0.001 and is reduced when the manganese composition Y is above 0.20. The dielectric loss is increased when the zirconium composition Z is below 0.001 and the saturation magnetization is reduced when the zirconium composition Z above 0.04. The manganese and zirconium need to be added at the same time. A lower dielectric loss is obtained when the composition is Ni0.6 ZnO0.4 Fe1.96 Mn0.03 Zr0.01 O4 .
