Title: Pulse width modulation controller for inverter
Inventor: OYAMA KAZUNOBU
IPC: H02M7/48
Filed: 1988-05-25
Abstract: PURPOSE:To calculate an ON time in a short time by dividing each calculated ON time into a plurality of pulses even if the calculating time of a pulse width modulation pattern is long, and equivalently raising a carrier frequency. CONSTITUTION:The pulse width modulation controller of an inverter drives a 3-phase winding induction motor 1 in which three windings 2a-2c are coupled in a Y-connection by a voltage type inverter 3. The inverter 3 has a transistor bridge circuit 4, and uses a 1-chip microcomputer 8 for forming the ON time (pulse width modulation pattern) of 6 transistors Tra-Trc'. A substitution table set to the types of the Tra-Trc' is stored in advance in the microcomputer 8. The pattern is repeatedly calculated at each calculating period responsive to its carrier frequency, it is divided into a plurality of pulses by dividing means to become similar to the magnification of the carrier frequency.

IPC: H04N1/411
Filed: 1987-05-25
Abstract: PURPOSE:To reduce the quantity of transmitting information by transmitting encoded data obtained by compressing and encoding a picture formed by reducing picture data and data indicating the exclusive OR of a picture obtained by reenlarging the reduced picture and an original. CONSTITUTION:Raw picture data stored in a memory 2 is reduced by a picture processor 3 and stored in a memory 4 for reduced data. The picture processor 3 enlarges this reduced data to an original size to take the data of the exclusive OR with the raw picture and store in a memory 5 for difference data. In an input and output device 6, the reduced data stored in the memory 4 is compressed by encoding, an enlargement ratio is added to transmit, and since the difference data stored in the memory 5 is a contour graphic, it is transmitted by a simple compressing method. Thereby, a compressibility is improved in comparison with the case the raw picture is directly compressed.

Title: Phase shift mask and its production
Inventor: KUSUSE HARUHIKO
IPC: G03F1/68
Filed: 1992-04-21
Abstract: PURPOSE:To obtain the phase shift mask which lessens the electrification of a substrate at the time of EB exposing in the production process thereof and generates less dust during handling and the process for production of this mask. CONSTITUTION:A phase shifter layer 3 is formed by spin-on glass or vapor deposition on a transparent conductive film 4 formed on a glass substrate 1 and thereafter, the phase shifter layer 3 in the peripheral part of the glass substrate 1 is etched away. After a conductive light shielding film 2 is formed on the treated surface, the light shielding film pattern and phase shifter pattern are plotted by EB exposing. The transparent conductive film 4 existing on the substrate 1 maintains a grounding potential at the time of the EB exposing and, therefore, the misregistration of the patterns by the electrification of the substrate 1 decreases. Since the peeling of the phase shifter material at the end faces of the mask substrate does not arise for its structure, the generation of the dust during the handling is lessened.
