Title: Pulse width modulator for pulse width modulation inverter
Inventor: MIZUTA MASAHARU
IPC: H02M7/527
Filed: 1982-01-08
Abstract: PURPOSE:To facilitate the integration of a pulse width modulation inverter by employing as firing angle instruction values electric angle information of the level varying point of a pulse width modulation pattern and the integer times sum of the electric angles corresponding to the phase difference of an inverter fundamental firing sequence. CONSTITUTION:The firing angle instruction value of thyristors S1-S6 in a 3- pulse type 3-phase current type PWM inverter is obtained from the electric angle information when the pulse width modulation pattern varies between ''1'' and ''0'' and the sum of the integer times of the prescirbed electric angle of 60 deg. corresponding to the firing phase difference of the inverter fundamental firing sequence. The fundamental firing sequence is advanced by the interrupt operation at every 60 deg. of the electric angle, the interrupt operation is waited to flow the PWM pattern firing sequence, thereby computing the firing angle insturction value. Accordingly, the firing angle instruction can be performed by the less number of bit length data, and the capacity of the memory can be reduced, thereby facilitating the integration of the inverter.

Title: Lens actuator
Inventor: NOMURA TADASHI
IPC: G11B7/09
Filed: 1986-01-09
Abstract: PURPOSE:To obtain a small-sized lens actuator with simple structure without using laser beams for an optical head part by arranging two reflection type proximity sensors on a condenser lens holding movable part with a fine interval so that the quantity of light detected by light receiving parts of respective sensors is changed mutually with reverse polarity. CONSTITUTION:Since area of a reflection surface corresponding to one of the reflection type proximity sensors 61, 62 is increased and a reflection surface corresponding to the other is reduced when the movable part 2 is shifted from a reference position in the tracking direction, a lens position error signal 71 corresponds to the shifted distance of the movable part from the reference position. Since the quantity of reflected light is not almost changed in spite of the movement of the movable part 2 in the focusing direction, the output of a sensor is not almost influenced. Although the intervals between the sensors 61, 62 and the movable part 2 are slightly changed by the movement in the focusing direction strictly speaking because the movable part 2 is supported by a focus supporting spring 3, the same change is applied to both the sensors 61, 62 and output components from the sensors 61, 62 are applied to a differential amplifier 7 as in-phase noise, so that the signal 71 indicates only the shifted distance of the movable part 2 in the tracking direction without being influenced by the change.

Title: Rolling method by edger
Inventor: KOKUBO ICHIROU
IPC: B21B1/22
Filed: 1984-01-10
Abstract: PURPOSE:To increase a width rolling reduction and to decrease the number of passes of the reduction in rough rolling by previously forming the cross-sectional shape of a rolling material into a downward convex one and rolling the material while supporting the deformation of the material by the reaction of a table roll at the time of subjecting the material to the width rolling reduction. CONSTITUTION:A rolling material S having a downward convex cross-sectional shape formed previously is fed to a pair of vertical rolls to be subjected to a rolling load F in its width direction. Because of its curved form, a displacement, i.e. an asymmetric quantity delta, is produced between a point of application at the end face of material S under the rolling load and a center of the material S on a table roll 11 for supporting the material S. The material S is subjected to a bending moment by the asymmetric quantity delta to bend further to the lower side. But the downward bending is restrained by the roll 11, and the material S can be therefore subjected to a larger width rolling reduction.
