When, for instance, a telephone conversation is carried on by way of an IP telephone terminal, a control section of the IP telephone terminal adjusts, through control of a comfort amplifier, the level of comfort noise so as to superimpose the comfort noise on a received voice signal in accordance with a private branch to which a telephone terminal on the other party of the telephone conversation is connected.

An end fence for use in a sheet feeding cassette includes an end fence main body attached to the sheet feeding cassette and movable along a sheet feeding direction, a device that fixes the end fence main body at any desired position in the sheet feeding cassette, and a sheet pressing element that presses against trailing edges of the sheets loaded on a bottom plate of the sheet feeding cassette. The sheet pressing element is provided to the end fence main body and movable in the sheet feeding direction and protrudes from the end fence main body forward in the sheet feeding direction when the sheet pressing element moves in the sheet feeding direction. The end fence further includes a biasing device that biases the sheet pressing element forward in the sheet feeding direction, and a bias force switching device that switches between a biasing condition and a non-biasing condition.

A clock generating circuit generates a clock of a rate corresponding to a Dch rate in response to a specification from the exterior. A counting circuit detects completion of reception of one frame by counting the clock number up to “11” at timing at which a start bit detecting circuit detects a start bit in a serial signal. An S/P converting circuit fetches a serial Dch signal bit by bit in synchronism with the clock, outputs the latest fetched 10 bits in a parallel form and latches eight bits of a real data portion among the output data into a latch circuit at the time when reception of one frame is completed. In parallel with the above operation, a parity calculating circuit and flag/interruption generating circuit set various flags and generate a reception completion interruption.

摘要:
A method of separating a plate-like workpiece held by adhesion on an elastic adhesive pad from the pad. The elastic adhesive pad has innumerable pores in its surface and generates adhesive force when negative pressure is produced by the pores, after being crushed, by restoration force generated by elasticity and adhesion. The method includes the step of heating the elastic adhesive pad at a predetermined temperature to separate the plate-like workpiece from the elastic adhesive pad by air expanding in the pores.
