Title: Delta-sigma modulator using shared capacitor
Inventor: FUJIMORI ICHIRO
IPC: H03M3/02
Filed: 1997-04-10
Abstract: PROBLEM TO BE SOLVED: To practically cancel all data dependent loads caused by following up an analog input voltage received at the shared capacitor of a modulator with an offset voltage through a load circuit. SOLUTION: A load circuit 70 generates the offset charge load of an inverse polarity in the same size as a charge load depending on data generated on a reference voltage source by a modulator 60. In the case of states Y=-1 and Y=1, shared capacitors 72 and 74 generate the prescribed load charges to loads Vref+ and Vref-. Then, when the absolute values of analog inputs Vin+ and Vin- of the inverse polarity are equal, the charge loading of capacitors Cm66 and 68 related to the Vin is canceled. This means that the charge loading of the reference voltage source does not have analog data dependency depending on the analog input at all. Namely, the reference voltage can be prevented from being affected by the analog input voltage Vin. Thus, a non-linear influence such as distortion caused by analog data dependence can be eliminated.

Title: Wire dot printing head
Inventor: TATEGAMI MASAHIRO
IPC: B41J2/28
Filed: 1990-04-09
Abstract: PURPOSE:To reduce magnetic interference due to leaked magnetic flux and realize the reduction of power dissipation and the increase of printing quantity per unit time by a method wherein a permanent magnet is arranged to be in contact with the end surface on the opposite side from the armature suction side of a core, and the vicinity of the side surface on the opposite side from the armature suction side of the core is demagnetized. CONSTITUTION:A core 21a is adjacent to a core 21b, and the core 21b is adjacent to a core 21c. Between the core 21a and core 21b, a nonmagnetic first base frame 24 is arranged, and in addition, under a core 21 and the first base frame 24, a permanent magnet 25 is arranged. Magnetic resistance of a leaking magnetic flux path is great, and demagnetization magnetic flux D generated at the core 21a is hard to leak to the core 21b. Therefore, almost all the demagnetization magnetic flux D is used for demagnetization of a suction magnetic flux C, and the quantity of the demagnetization magnetic flux D is not reduced, and therefore, it is equal that inductance of a coil becomes larger. Therefore, e.g. when an armature 16a is driven, electric current to be connected with a coil 2a can be made smaller.

Title: Color field detection circuit
Inventor: ASADA KENICHI
IPC: H04N9/64
Filed: 1996-04-15
Abstract: PROBLEM TO BE SOLVED: To detect a color field correctly with immunity to effect of noise by detecting an odd number field or an even number field from a video signal of the NTSC system so as to easily detect a color frame thereby using a color subcarrier in the video signal. SOLUTION: An input section 1 inputs a video signal of the NTSC system, and it is converted into a digital signal, which is fed to an arithmetic comparison section 3. On the other hand, a storage section 2 stores a signal pattern of a synchronizing signal predetermined by the video signal of the NTSC system. Then the arithmetic comparison section 3 receives the digital video signal from the input section 1 and the synchronizing signal pattern from the storage section 2, conducts comparison and arithmetic operation for synchronizing signals in the video signal to discriminate the color field from the video signal of the NTSC system. Since the detection of the synchronizing signal is discriminated based on a consecutive number from a prescribed level or below, the color field is detected correctly with immunity to effect of noise.
