Title: Information recorder
Inventor: NAGANO HIROBUMI
IPC: G11B20/18
Filed: 1990-01-30
Abstract: PURPOSE:To improve versatility by differentiating a detection signal corresponding to light reflected from a recording medium, computing the AND of a pulse signal obtained by comparing a prescribed value and a recording signal and deciding the existence of abnormality with the aid of comparing the AND and the recording signal. CONSTITUTION:An optical pickup 12 and an RF amplifier circuit 14 detect the light reflected by the recording medium 11 of a light beam and output the detection signal corresponding to the reflected light. A differentiation circuit 16 differentiates a reflected light signal outputted by the amplifier circuit 14 and outputs it to a comparison circuit 17. The circuit 17 compares the differenciated signal outputted by the differentiation circuit 16 with a signal having a prescribed value and outputs a rectangular pulse signal to an AND circuit 18. The circuit 18 computes the AND of the rectangular pulse signal and the recording signal. Then, a counting circuit 19 compares the AND with the recording signal and judges the existence of a recording defect. Thus, the need of a drastic change is eliminated with respect to the change of the recording medium 11 or the like and the versatility is improved.

Title: Controller for combustion apparatus
Inventor: TANAKA HIROSHIGE
IPC: F23N5/10
Filed: 1993-01-14
Abstract: PURPOSE:To rationally correct an error occurring based on an offset voltage of an operational amplifier when an output voltage of a microvoltage output type sensor is amplified by the amplifier. CONSTITUTION:When a correction value write command signal generator 4 applies a first signal to a control circuit 3, the circuit 3 applies a specific input voltage Vin to an input of an operational amplifier 2. The circuit 2 also compares an actual output voltage present at the output of the amplifier 2 with a theoretical output voltage previously written in a ROM 7 corresponding to the specific voltage Vin to obtain correction data based on the error and stores it in an EEPROM 5. After the generator 4 stops outputting of the first signal, the circuit 3 obtains correction voltage data by considering correction data stored in the EEPROM 5 for the actual output voltage of the amplifier 2, and controls a combustion apparatus based on it.

Title: Developing device of magnetic printer
Inventor: HOKARI MAMORU
IPC: G03G19/00
Filed: 1985-02-07
Abstract: PURPOSE:To fix the quantity of toner stay and to improve the printing quality by rotating an eccentric cams formed on both the sides of a developing roller supported by a developing frame supported by a spring through a sensor for measuring the height of magnetic toner to control a gap between a magnetic medium and the developing roller. CONSTITUTION:When the quantity of toner stay is reduced, the opening area of a photosensor photodetecting part 31 or 32 is increased and the quantity of photodetection is increased. When the quantity of the toner stay is increased, the quantity of photodetection is reduced. Since the eccentric cams 27, 28 are always contacted with a magnetic drum 33 by a spring 30, the cams 27, 28 are rotated in the arrow (f) direction at the decrease of the toner stay and the increase of the photodetection, a developing gap (d) is reduced, passing toner is limited to increase the quantity of the toner stay. When the quantity of toner stay is increased, the cams 27, 28 are rotated in the arrow (g) direction, the developing gap (d) is increased to reduce the toner stay. Consequently, the quantity of toner stay, i.e. the contact length l between the magnetic drum 33 and the toner 33 is kept at a fixed value by repeating said two operations, so that images of high printing quality can be obtained.
