Abstract: A character pattern generation apparatus generates a character pattern on the basis of font data in a stroke format. A data generation unit generates character data, character element data, or stroke data on the basis of the font data in the stroke format. A storage unit stores the character data, character element data, or stroke data generated by the data generation unit. A discrimination unit discriminates whether character data, character element data, or stroke data corresponding to a character pattern to be generated is stored in the storage unit. When the discrimination unit determines that character data, character element data, or stroke data corresponding to the character pattern to be generated is stored in the storage unit, a character pattern generation unit generates the character pattern on the basis of the character data, character element data, or stroke data stored in the storage unit.

Abstract: An actuator for controlling the pressure in an internal space defined by a spring-biased diaphragm and a housing by solenoid valve. The internal space is selectively communicated with a negative pressure port or an atmospheric pressure port through a first solenoid valve. The pressure in the internal space is determined by the ratio of a time period in which it is communicated with the negative pressure port to a time period in which it is communicated with the atmospheric pressure port, and the position of the diaphragm is determined accordingly. Another solenoid valve for releasing negative pressure is included for safety. To the housing fixed are a microcomputer for receiving status signals from a vehicle speed sensor, clutch ON/OFF sensor, brake ON/OFF sensor, etc. to generate a solenoid valve opening and closing signal, and a printed board incorporating an electrical driver adapted to energize the solenoid valve in response to said signal.
