Title: Controlling method and apparatus for pulse width modulating inverter
Inventor: MUTOO NOBUYOSHI
IPC: H02M7/527
Filed: 1980-01-11
Abstract: PURPOSE: To reduce the number of comparators for comparing a modulating level with a triangular wave and the number of resistors for setting the modulating levels by employing the waveform stepwisely reduced in the modulation level as modulation wave.  
     CONSTITUTION: The triangular wave of a triangular wave generator circuit 101 is converted into a rectangular wave via a rectangular wave generator circuit 102 for driving a scale of 21 ring counter 103. The output of the ring counter 103 is applied to a gate logic circuit 107. On the other hand, the output of the triangular wave generator circuit 101 is converted to positive and negative symmetrical absolute value waveform, which is in turn applied to a comparator circuit 106. To the comparator circuit 106 are applied three level outputs D 1 , D 2  and D 3  of a modulating level generator circuit 105, and the comparator circuit 106 couples any of the outputs of the phases U, V and W produced as comparing the levels with the absolute value waveform to the gate logic circuit 107. Thus, the circuit for comparing the modulating level thus set with the triangular wave can be simplified.

Abstract: PURPOSE: To etch an SiO 2  or PSG film placed in the center of a hole made in a thin polyester plate with a high rate of selection by the use of a C 4 F 8  gas and/or a mixed gas of C 4 F 8  and He.  
     CONSTITUTION: Material 4 to be etched which consists of an Si substrate with an SiO 2  or PSG film formed on the substrate is placed on a flat electrode 3, and a thin polyester plate 6 is provided in such a way that it surrounds the material. When the diameter of the material to be etched is d mm, that of the plate 6 is to be larger than d by 10W40mm, and if the plural number of the materials are simultaneously etched, a gap of wider than 10mm is provided between the adjacent holes. If the hole dimension of the plate 6 is less than the specified, the progress of etching is impeded because a product of polymerization reaction is accumulated on the surface  of the material to be etched, and if the dimension is larger than the specified, the effect of improving an etching speed ratio is lowered. If reactive sputter-etching is made using a C 4 F 8  gas or a mixed gas of C 4 F 8  and He, the etching speed ratio reaches 15 or over, and it is thus possible to make a minute process.
