Abstract: An automatic ice making machine 1 includes an ice tray 2 for making ice cubes, ice separating means 5 for separating ice cubes from the ice tray 2 by turning the ice tray 2, and an ice storage container for storing separated ice cubes. A stepping motor 13 is used for a drive source for the driver unit 5. The automatic ice making machine further includes detecting means for detecting a predetermined position of the ice tray 2; and control means for controlling a drive of the stepping motor 13. When the ice tray 2 is returned to the water supply position, the control means determines a predetermined position of the ice tray 2 by use of a signal from the detecting means, and determines other positions of the ice tray 2 by the utilization of the number of steps of the motor counted from the predetermined position.

Abstract: In an opening/closing member driving method in which the rotation of a motor rotatable in two directions is transmitted through a transmission member to an opening/closing member to thereby drive a baffle 4 in an opening direction A and in a closing direction B, when driving the transmission member from an intermediate position to an original position which is set at a position where the transmission member is moved to the full in one direction or in the other direction, the transmission member is once driven in the opposite direction to the original position and is stopped at such opposite position or in the neighborhood of the opposite position and, after then, the transmission member is driven in the original position direction by an amount equivalent to the normal movement thereof and is thereby returned to the original position.

Abstract: A digital signal has frames each composed of n data words and a parity code. One data word has m bits. The letters n and m represent natural numbers equal to or greater than 2. One frame of data words is written into a memory. When writing of one frame of the data words into the memory is completed, a write end flag is generated and written in the memory. After the detection of the write end flag, the data words are read out from the memory. An error is detected from the read data words and is corrected.

Abstract: A first digital sound data of N-bits delivered from the input terminal is controlled by a mute control signal indicating either on-mute state signifying the state where mute operation is conducted or off-mute state signifying the state where no mute operation is conducted. This circuit includes a level control circuit, a register, a bit shift circuit, and a data selector. The level control circuit outputs a second digital sound data corresponding to the soundless state at the time of on-mute. It outputs data of which level gradually rises from the level of the soundless state to the level indicated by the first digital sound data at the beginning of off-mute and outputs the first digital duration at times subsequent thereto. Thus, for a duration at the beginning of off-mute, sound volume gradually rises. The register and the bit shift circuit gradually attenuate the first digital sound data to the level of the soundless state. Thus, for a duration at the beginning of on-mute, sound volume gradually lowers.
