Abstract: A horizontal display size compensation circuit for a monitor prevents a horizontal display size of a monitor screen from being changed when a horizontal frequency varies according to a video mode. A horizontal frequency is generated by a horizontal frequency generation section corresponding to each video mode. A microcomputer generates a predetermined horizontal display size compensation signal according to the horizontal frequency corresponding to each video mode and a horizontal display size adjustment signal corresponding to an input of a key input section, and a horizontal display size control section controls a horizontal display size of the monitor screen by supplying the horizontal display size adjustment signal of the microcomputer and the horizontal display size compensation signal to the horizontal frequency. Therefore, a horizontal display size of a monitor screen is prevented from varying according to a video mode.

The support ledge has a slot extending generally in parallel to the vehicle frame and receiving the head of the bottom positioning bolt. The pump motor mounting arrangement further includes a top fixture plate for, when tightened, depressing the upper extension of the motor bracket against the vehicle frame to keep the pump in place and for, when loosened, allowing the pump motor to be slidingly moved on the support ledge into a temporary maintenance position.

Abstract: Methods are provided for inhibiting and allowing alarm handling and displaying when an alarm is inhibited in a digital cellular system. A method for inhibiting alarm handling in a digital cellular system includes the step of inputting an Inhibit Alarm On/Off (INH-ALM-ONOFF) command in a base station manager (BSM). The range of the system to inhibit alarm handling and the type of alarm to be inhibited is set up. An option of inputted variables corresponding to the steps of setting up the range and the type of the alarm are checked. A state of equipment of program loaded data (PLD) is checked to determine whether one of a component group and components groups of the digital cellular system corresponding to the range is in use. It is then determined whether the alarm has occurred. Counts are reduced by as many times as occurrences of the alarm and clearing the alarm, when the alarm has occurred. It is then determined whether the alarm is performed with an Inhibit Alarm Message (INH-ALM-MSG).

Abstract: A phase shift mask is fabricated by forming a radiation blocking layer on a phase shift mask substrate and forming a photoresist layer on the radiation blocking layer. First portions of the photoresist layer are exposed at a first exposure dose. Second portions of the photoresist layer are exposed at a second exposure dose that is greater than the first exposure dose, such that the second portions of the photoresist layer are wider than the first portions of the photoresist layer. The radiation blocking layer is etched using the photoresist layer as an etch mask, to thereby produce first apertures in the radiation blocking layer beneath the first portions of the photoresist layer and second apertures in the radiation blocking layer which are wider than the first apertures, beneath the second portions of the photoresist layer. The phase shift mask substrate is then etched beneath the second apertures.
