Title: Pwm type d/a converter
Inventor: TANAKA YOSHIKAZU
IPC: H03M1/82
Filed: 1990-10-23
Abstract: PURPOSE:To improve the resolution of the this converter without changing the frequency of a clock signal by changing at least one of the outputs of four PWM converters whenever an input signal changes by one unit. CONSTITUTION:Four PWM converters 2-5, analog adders 7 and 8, an analog subtracter 9, and a smoothing circuit 10 are provided. Then, by changing one of the pulse widths of the plural PWM converters whenever input signals change by one unit, the pulses of the PWM converters 2 and 3 belonging to the 1st group are widened in width proportionally to the input signals and the pulses of the converters 4 and 5 belonging to the 2nd group are made to become the inverted signals of the input signals. In other words, the output of this D/A converter is changed against a change in the input signals by adding the outputs of the converters 2 and 3 belonging to the 1st group and subtracting the analog sum of the converters 4 and 5 belonging to the 2nd group. Therefore, the resolution of this D/A converter can be improved.

Title: Facsimile equipment
Inventor: MORI AKIKO
IPC: H04N1/00
Filed: 1987-11-13
Abstract: PURPOSE:To omit operation for manufacturing the cover of a sent document at each time of transmission by registering figures, characters, etc., which constitute the cover in the facsimile equipment. CONSTITUTION:At an operation part 1, an operator inputs data such as an address required for the cover of the document and registers them in a storage part 3. When a transmission destination is specified, a control part 2 selects necessary data among data in the storage part 3 and passes the data to a communication control part 4 in combination with a format stored separately. The communication control part 4 converts them into image information and sends it out to a line. Consequently, the operation for forming the cover every time transmission is performed is omitted.
