Title: Image-forming apparatus loaded with multibeam laser
Inventor: ISHII TETSUYA
IPC: B41J2/44
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To eliminate jitter generated by mirror contamination or the like by comparing a response time difference measured by a beam detector(BD) sensor with a natural time difference of the BD sensor, calculating a time difference deviation and adjusting an image write position based on the calculated value. SOLUTION: When mirror contamination is brought about in a rise edge part which executes BD detection to a first laser light, a width t1 becomes smaller than at a normal time. For correcting this, a CPU reads each BD pulse width of the first laser light and a second laser light by an AD converter, and calculates a missing part Δt1 (=t2-t1) of t1. A lighting timing of the first laser light is delayed by a time of Δt1+t1+tb from a lighting timing of the second laser light. An exposure position in a main scanning direction on a surface of a photosensitive drum is thus registered. The correction to write positions of a laser light 1 and a laser light 2 can eliminate BD jitter caused by a variation of the BD pulse width.

The high-temp. combustion gas from burners 11 of a combustion furnace 12 provided on one side of the rotary furnace 30 passes through the gas chamber 6 to indirectly heat the raw material mixture. The Cr2O3 of the Cr ore is solid-phase reduced by the carbonaceous reducing agent to Cr7C3 which is discharged from a take-out port 16. The gaseous CO formed by the reduction reaction of the Cr2O3 is sent by a pressurizing blower 32 from a gas withdrawing pipe 31 to the burners 11 and is used as the heat source for indirect heating to effect the reduction reaction of the raw material mixture in the furnace core chamber 5.

Title: Shift controller for automatic transmission
Inventor: BABA FUMIAKI
IPC: B60W10/10
Filed: 1989-04-07
Abstract: PURPOSE:To raise the temperature of a hydraulic fluid as well as to make a line pressure controllable as desired by changing a shift characteristic so as to cause a driving range of at least first gear speed to be narrowed when temperature in the hydraulic fluid for a torconverter and a friction element is cold more than the specified value. CONSTITUTION:Oil temperature is read in together with car speed and throttle opening, and whether the present oil temperature is less than -10 deg.C or not is discriminated. When NO is the case, a duty ratio D to a line pressure regulating solenoid 7 is determined, whereby a shift characteristic for usual time is selected, and shift control is performed. When YES is the case, the duty ratio to the solenoid 7 is set as zero percentage, and thereby whether when vehicle running load is large or not is discriminated, and when NO is the case, a shift characteristic for cold time is selected, but when YES is the case, the shift characteristic for the usual time is selected the other way. Thus, a cold state is quickly getting out, raising temperature in a hydraulic fluid, thus a shift shock can be prevented.

IPC: B65H7/12
Filed: 1985-04-25
Abstract: PURPOSE:To make the double feed of a cut sheetlike body discriminable so surely with a simple device, by installing a detecting device inclusive of a mechanical-electric conversion element outputting according to thickness of the sheetlike body and another device discriminating a feeding state of the sheetlike body based on the output. CONSTITUTION:When recording paper is inserted into a space between a platen 1 and a pinch roller 3, a plate spring 5 is bent by displacement of this pinch roller 3, and this deformation is detected by a strain gauge 6. And, a difference between an output value epsilon of an amplifier A1 at this time and an output value epsilon0 of the amplifier A1 just before paper feeding is found by an amplifier A2, and when epsilon1 is set down to the output value of the amplifier A1 equivalent to thickness of one sheet of standard recording paper, if epsilon-epsilon0<epsilon1 is the case, it means that the recording paper is no longer fed thereto, if epsilon1<=epsilon-epsilon0<2epsilon1 is the case, it means that normally one sheet comes to be fed in consequence. In addition, if 2epsilon1<=epsilon-epsilon0 in the case, it is judged that the paper is fed double. Thus, a feeding state of a sheetlike body is surely discriminable with a simple device.

Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To restore function of ink jetting to the satisfactory state by surely discharging defective ink-containing bubbles at flushing after purging. SOLUTION: With a signal for purging command outputted at the step 100, a recording head is moved to a purging position at the step 110 and purging is made at the step 120.
