摘要： A squelch circuit for a radio transmitter/receiver includes an amplifier, a digitally-controlled electronic volume control, a volume adjusting variable resistor, and a volume controller. The amplifier amplifies a received audio signal input and provides the received audio signal to a loudspeaker. The digitally-controlled electronic volume control changes the output level of the amplifier. The volume adjusting variable resistor outputs data representing a volume value. The volume controller constantly detects changes in volume value data output from the variable resistor, and controls an attenuation amount of the digitally-controlled electronic volume control in accordance with the volume value represented by the variable resistor. While in a "mute" state, this volume control continues until a predetermined time has elapsed since the detection of the change in volume value data. The volume controller then sets the attenuation amount of the digitally-controlled electronic volume control to an infinite attenuation amount.

摘要： Gains and offsets of the input-output characteristic of a second side reading unit are controlled so as to match input-output characteristic of a first side reading unit on the basis of image data of a gray chart read by the first side reading unit and the second side reading unit. Then, on the basis of image data of a color chart read by the first side reading unit and the second side reading unit, offsets of the input-output characteristic of the second side reading unit are controlled for individual color components such that differences between color read by the first side reading unit and color read by the second side reading unit are reduced.

摘要： An LED array head for an electrophotographic system includes a base plate mounting thereon a number of linearly arranged LED chips and a support member holding the base plate. The base plate and the support member are bonded together by means of a principal adhesive agent which is elastic after hardening such as a silicone type and an auxiliary adhesive agent which hardens more quickly and is less elastic after hardening than the principal adhesive agent. An ultraviolet ray setting type adhesive agent is preferably used as the auxiliary adhesive agent. Assembling steps of such LED array heads can proceed without waiting for hardening of the principal adhesive agent.
