Abstract: Method and apparatus for igniting fluorescent lamps at a predetermined temperature of their cathodes. In the present invention, it is the resistance of the cold lamp cathodes that is always measured and ignition occurs as a result of the relationships or conditions of the cold resistance to the hot resistance or the voltage relationship of cold to hot, so that the absolute value has no influence and correct preheating is achieved with all types of lamps.

Abstract: A power control unit protection apparatus is provided in association with a power control unit for controlling high or low power supply selectively to a loud speaker. The power control unit protection apparatus has an average current detector for detecting an average current supplied to a transformer, a temperature detector detecting the temperature of the transformer, and a timer. When the average current exceeds a predetermined level, and when the temperature rises above a predetermined temperature, timer starts to count a predetermined time. After the count, a cut off signal is produced to cut off the use of the high power supply from the power control unit. Thus, the power control unit protection apparatus prevents breakdown due to overheating of the power control unit including the power supply transformer by limiting the power supplied to the speaker.

The arrangement is such that this laser light is incident on the scanning deflector along the optic axis of the scanning lens, and a screen is provided for obstructing ghosting in the vicinity of the scanning surface. Further, either the side of the prism block on which the light is incident or the side from which it emerges is curved, or both are curved, or one side of the prism block is treated to prevent reflection. Further, a screen is provided between the laser light source and the slit mirror so as to obstruct that part of the light incident on the mirror which is reflected by the mirror after being reflected by the scanning deflector.

Abstract: A parallax compensation system in a camera finder includes a mirror surface mounted to a mounting member. The mounting member is rotatably mounted to a mounting frame having protrusions about which the mounting member rotates such that the mounting member is rotatable about an axis defined on the mirror surface. A cam mechanism is rotatably mounted on a top surface of the mounting frame for regulation of the mounting member to have a predetermined position. An urging member biases the mounting member against the cam mechanism, so that when the cam mechanism is rotated, the mounting member is rotated about its axis according to a cam surface of the cam mechanism. The mounting member is rotated about the axis of the mirror surface to change an optical axis of the same to compensate for parallax.
