Title: Thin-film magnetic head
Inventor: MIMA SOUICHIROU
IPC: G11B5/31
Filed: 1982-07-29
Abstract: PURPOSE:To obtain the parallelism between a recording head gap and a reproducing head gap with high precision through easy assembling operation, by fixing a thin film magnetic recording head and a thin-film magnetic head together in one body with spacers inbetween. CONSTITUTION:The spacers 21 and 22 are sandwiched between protecting substrates 14 and 18 at their upper end and lower end parts, and both left and right end reference surfaces 23 of those spacers 21 and 22 are GC-lapped to have high-prescision parallelism. Even if the total of left-right difference in length between the two spacers 21 and 22, thickness unevenness of adhesive layers between the spacers 21 and 22, and substrates 13 and 17, etc., is about 5mum, substrate surfaces 13a and 17a slant at about 2' angles when head width l is 8mm.. A reproducing head gap is considered to be at the same position with the substrate 17, so the azmiuth angles of the recording and reproducing head gaps are about 2'.

Title: Method and device for cleaning of developer
Inventor: ITAYA MASAHIKO
IPC: G03G21/00
Filed: 1981-08-24
Abstract: PURPOSE:To collect the toner in a reusable state without impairing the surface of an electrostatic image holder and at the same time to obtain the high cleaning performance, by transcribing electrostatically the toner on the electrostatic image holder onto an insulated film. CONSTITUTION:A film 2 is conductive on its single side and insulated on the other side, and this insulated side is set close and opposite to an electrostatic image holder 1. The DC/AC voltage having the polarity adverse to the developer residual on the holder 1 is applied between the holder 1 and the film 2. In such way, the residual developer particles are separated from the holder 1 and can be transferred to the film 2.

Title: Pulse motor control method and image forming device
Inventor: TSUCHIYA SHIZUO
IPC: B41J11/42
Filed: 1996-05-28
Abstract: PROBLEM TO BE SOLVED: To provide a pulse motor control method and an image forming device for keeping the printing performance of high picture quality while controlling heat development of a motor. SOLUTION: Respective sections of a thermal color printer 1 are drive controlled by a control section formed on an electronic circuit base of an electrical equipment section 5. Printing indication is input from an operation panel 17. A paper feed lever 7 and a ribbon take-up roll 14 are driven by a ribbon motor through a one-direction clutch, and a platen roller 9 is driven in both of forward and reverse directions by a paper feed motor. When the paper is positioned and the operation is stopped before the start of printing, or when color ink is positioned and the operation is stopped until the start of printing, or else when the operation is stopped temporarily at the time of moving forward or reverse the paper P as represented by the both direction arrow marks C for the purpose of overlapping inks of three colors or four colors, the excitation to respective motors is continued.  At the time of stopping other than the above- referred stops, the excitation to the motor is shut off. Also when the time more than the given time is passed during the excitation, the excitation is shut off similarly.

Title: Color image recorder
Inventor: NAKATSUKA KIMIHIRO
IPC: G03G15/01
Filed: 1991-05-08
Abstract: PURPOSE:To record a color image for simulating the diffusing of the ink of the circumferential part of a dot at the time of printing. CONSTITUTION:Synthetic dot signals Sdy1, Sdm1, and Sdc1 that the dots of each plate of Y, M, and C, are synthesized with the dot of a K-plate, are extracted as the signals of 12 bits that the dot signals of one scan have the addition of two dot signals of the next scan, and inputted into filtering circuits 205y, 205m, and 205c, attaining filtering with a weighting function as the matrix of 3X3. Consequently, the dot signals of each plate are outputted after the circumferential part of the dot is smoothened, and beams for an exposure are modulated, based on these outputted scattering/simulating dot signals Sdy2, Sdm2, and Sdc2, to obtain a color image for correcting.

Title: Automatic cut sheet feeding system for recording device
Inventor: KASHIMURA MAKOTO
IPC: B65H29/00
Filed: 1985-06-19
Abstract: PURPOSE:To make a system structure simplifiable, by warning an operator with a first mode when a detecting device detects 'no paper' even after operation of a cut sheet feeding device but with a second mode when it detects 'some paper' even after operation of a discharging device, respectively. CONSTITUTION:A paper feed roller 12 of a cut sheet feeder is driven for rotation, and each cut sheet 35 of a bundle 1 is fed till it strikes against an interval between a platen 152 and a pinch roller 156, but at this time, if a paper end sensor 57 detects 'no paper', an alarm lamp is lighted in succession, warning an operator of the 'no paper'. On the other hand, when the sensor detects 'some paper', the cut sheet is fed up to a printing start position with rotation of the platen 152, therefore printing takes plate with a printing head 63, and when a paper end run past between a pinch roller 154 and the platen, a paper discharge roller 20 is rotated and thus paper discharging is carried out. At this time, if the paper end sensor 57 has detected 'some paper', the alarm lamp blinks as judging that a paper jam happens there, warning the operator of it. Thus, a system structure is sharply simplifiable.

Abstract: PURPOSE:To eliminate an overcurrent at output terminal shortcircuiting time by connecting one terminal of a DC bias power source of a DC/DC converter through a diode with the output terminal. CONSTITUTION:One terminal of a DC bias power source 8 is connected through a diode 11 with the positive side terminal of a smoothing filter 4. When a load 5 is shortcircuited, the voltages of the windings of an oscillation transformer 6 becomes near zero, transistors 7, 7' are turned ON by the charge stored in a capacitor 10, and an overcurrent tends to flow flow. However, since the charge of the capacitor 10 is discharged through a diode 10 to discharge to the shortcircuited load 5, the transistors 7, 7' do not turn ON, and no overcurrent flows.
