IPC: H03M3/02
Filed: 1988-02-16
Abstract: PURPOSE:To perform conversion with high accuracy in a wide band area by performing quantization by adding an accumulated value corresponding to the output of a first voltage controlled oscillator where an input signal is supplied, and subtracting the accumulated value corresponding to the output of a second voltage controlled oscillator to which the inversion signal of the input signal is supplied.

The VCO circuit 3a oscillates proportionally to the integration voltage, and the VCO circuit 3b oscillates inversely proportional to the integration voltage. The number of output waveforms of the VCO circuit is counted at an up/down counter 4 asynchronously with a sampling frequency fs. The circuit 4 adds the number of waves of the oscillation waveform output of the circuit 3a on the accumulated value, and also, subtracts the number of waves of the oscillation waveform output of the circuit 3b from the accumulated value, then, outputs a result to a D/D conversion circuit 5.

Title: Drum for vtr
Inventor: KANEKAWA ICHIRO
IPC: G11B15/61
Filed: 1996-01-25
Abstract: PROBLEM TO BE SOLVED: To prevent squeaking or sticking of a tape during a tape is sliding by etching the sliding surface of a drum which touches a magnetic tape so as to form a optimum amt. of projections of particles having high hardness on the sliding surface. SOLUTION: This AHS drum 1 for a VTR consists of an AHS material having dispersion and precipitation of Si particles in an Al matrix. For example, this material is dipped in a 20% H2 S04 soln. for a specified time for etching treatment. The surface 1a of the AHS drum 1 which is exposed by the etching treatment has projections of Si particles. This is because when the AHS drum 1 is dipped in a 20% H2 S04 soln., the Al matrix dissolves but Si particles do not dissolve. Therefore, by applying a 20% H2 SO4 soln. on the sliding surface 1a of the drum 1 to etch the sliding surface 1a only, Si particles can be projected on the sliding surface 1a of the drum. Thereby, squeaking or sticking of a magnetic tape during the tape is sliding can be prevented.

Title: Inverter
Inventor: MIKI OSAMU
IPC: H02P23/16
Filed: 1993-02-23
Abstract: PURPOSE:To prevent unstable revolution of an a.c. electric motor caused by an error in a signal representing the number of revolutions, in a construction in which feedback control of the a.c. electric motor is carried out on the basis of the signal representing the number of revolutions of the a.c. electric motor. CONSTITUTION:The drawing shows an operation stabilizing routine which is carried out when a controller performs feedback control. When a difference DELTAf between the maximum value and the minimum value of a feedback frequency, which is calculated on the basis of a signal representing the number of revolutions fed back from an electric motor, is not more than a predetermined constant value, the controller concludes that a reason for the variations in the feedback frequency is attributable to delays in reading a signal Sn of the number of revolutions and an error due to a reading accuracy. The controller carries out a feed forward control instead of the feedback control while an output frequency instruction value is decided. Such feed forward control is continued until the feedback frequency varies more than a limited amplitude for variations in load.
