Title: Ink jet recording apparatus and ink recording method
Inventor: ARAI ATSUSHI
IPC: B41J2/175
Filed: 1991-12-19
Abstract: PURPOSE:To maintain stable ink ejection performance for a long time for a recording head in separate type for which a plurality of ink tanks can be used alternately by a method wherein driving conditions for the recording head are changed in accordance with the frequency of use of the ink tanks for one recording chip. CONSTITUTION:In the case where an ink tank 1 is used, reference temperature for controlling the temperature is set at a first set temperature T1. As the ink in the first ink tank 1 is consumed and the tank 1 is replaced by a tank 2 and as the tank 2 is mounted to the same recording chip, driving condition for the recording head is changed downward by setting the reference temperature for controlling the temperature at a second set temperature T2. Thereby, high quality recording images can be formed for duration of the recording by the tank 2 with less variation in recording density and with efficiency relatively better than the previous recording. When a tank 3 is mounted likewise, the driving condition is changed downward further with setting made at a third set temperature T3. By employing methods as mentioned above, a large amount of ink, larger than in the case of mounting a single ink tank, can be used without allowing changes to occur in its characteristic, and formation of quality recording images can be made stably for a long time with the recording chip.

Title: Semiconductor laser driver
Inventor: NAGATA MASAYA
IPC: G03G15/22
Filed: 1991-12-20
Abstract: PURPOSE:To accurately control an optical output of a semiconductor laser while maintaining the oscillation wavelength of the laser constant. CONSTITUTION:The semiconductor laser device comprises a current driver 11, and a current driver 12. The driver 11 supplies a drive current to a semiconductor laser 3. The driver 12 generates a video current Im to turn ON, OFF in response to a video signal. The driver 12 absorbs part of the drive current from the driver 11 as a video current Im to modulate the drive current. A photoelectric element 14 converts a monitored optical output of the laser 3 into a current. A current/voltage converter 15 outputs a monitored voltage Vm. A comparator 16 compares the voltage Vm with a reference voltage Vs, and outputs a high/low signal. A counter 17 increments or decrements the counts of clocks by a control signal of a controller according to the high/low signal. A constant-current source 20 outputs a drive current corresponding to a current control signal from a D/A converter 18.

IPC: G03G15/08
Filed: 1990-11-30
Abstract: PURPOSE:To smoothly replenish toner from a hopper separated and fixed by means of a simple mechanism by varying the length of a path along which toner is replenished according to the lifting positions of developing units. CONSTITUTION:The toner replenishing path 7 can be extended/reduced by joining joint pipes 71 to 73 successively and toner from a guiding part 6 is carried to the side of the developing units along the path 7. When the toner is supplied to a photosensitive drum 18 from the developing unit 84, the toner replenishing path 7 is reduced. On the other hand, when the supply of the toner to the photosensitive drum 18 from the developing unit 84 is completed, the path 7 is moved to the downward of the developing unit 8 to be switched to another developing unit. According to the movement, the toner replenishing part 7 is extended. Toner T is supplied to the developing unit through the toner replenishing path 7. Since the joint pipes 71-73 are bigger successively in the size of diameter, the toner T carried along the joint pipes 71 to 73 is not stagnated at the joints of the pipes 71-73. Thus, the toner can be supplied from the hopper 2 separated and fixed by means of the simple mechanism.
