Filed: 1996-02-15
Abstract: PROBLEM TO BE SOLVED: To effectively use a fan, and lengthen the life of an ozone filter without requiring a special mechanism and an excess space by switching an air duct by the fan arranged in a device main body. SOLUTION: A solenoid is arranged in a proper place of an immovable part of a device main body under an air duct R, and in an energy absorbing position of the solenoid, a wind shielding plate 8 descends by dead weight, and opens an opening 7. When the solenoid is energized, the wind shielding plate 8 rotates, and blocks up the opening 7. At standby time of an image forming device, a fan 1 rotates at half speed, and the solenoid is turned off, and since the opening 7 is opened, an air current becomes two ways of a black arrow and a void arrow, and the air current passing through an ozone filter 2 extremely reduces coupled with half speed operation of the fan 1. At copy actuating time, the fan 1 rotates at full speed, and the solenoid is turned on, and since the wind shielding plate 8 blocks up the opening 7, the air current becomes only a black arrow part, and ozone can be sufficiently removed coupled with full speed rotation of the fan 1.

Filed: 1993-03-11
Abstract: PURPOSE: To improve the reliability of a data storage device that uses a run length limited code that is modulated in a high code ratio and a related detector by increasing the smallest distance between output matrixes of a partial response channel. CONSTITUTION: A Viterbi detector arranges the shortest distance decision identifying circuit 70, path memories 72 and 74 and a multiplexer MUX 108 in each addition, comparison and selection ACS device 100. When a control signal of a line C is zero, time change that is given by an MUX 107 is de-energized. Even though the line C is zero, a circuit 70 is biased by an inverter 85, and furthermore, when the memories 72 and 74 are biased, an output signal is given to a line 84. Thereby, the MUX 108 is biased and the shortest distance that is needed is given to states 0 and S. At the same time, if signal edge states 0 and S or 1 and S are eliminated, an MUX 105 is biased to generate the same metric that is given. Thus, the circuit 70 is contained in a grid structure in which the Viterbi detector temporally changes.
