Title: Recording apparatus
Inventor: ODA NAOKI
IPC: B41J19/18
Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To provide a recording apparatus which can obtain high-quality print results by eliminating a velocity instability because of a load change of a carriage motor in a simple constitution. SOLUTION: A portable printer 1 feedback controls a CR motor 30 for driving a carriage 27 transferring printing heads 15, 16. A load applied to the motor increases because a feed tube 12 for feeding ink to the printing heads 15, 16 comes in touch with a main body frame 6 at a predetermined place. A PID constant of a PID control is changed beforehand in accordance with the load, so that a gain of a control signal output to a CR motor driver is changed. The motor can be converged to a constant velocity immediately even when a large load is generated. Accordingly, the printer is stable in velocity and can obtain high-quality print results.

Filed: 1985-10-31
Abstract: PURPOSE:To contrive the improvement in resistance to corrosion and abrasion without deteriorating a soft magnetic characteristic by specifying the composition ranges of Fe, Al and Ge and substituting at least one of them by Ru of specified atm% in an alloy thin film of Fe-Al-Ge group. CONSTITUTION:This soft magnetic thin film is expressed by a composition formula FeaAlbGec (wherein a, b and c represent the respective composition ratio by atm%) and their composition ranges are 69<=a<=84, 1<=b<=31, 1<=c<=31, a+b+c=100. At least one kind of Fe, Al and Ge is substituted by Ru of 0.1-10atm%. Thus, the addition of Ru into the Fe-Al-Ge group alloy basically composed of Fe, Al and Ge influences upon the improvements in the resistances to abrasion and corrosion remarkably. Also, the deterioration of the soft magnetic characteristics due to the addition of Ru hardly occurs and the reduction of a saturation magnetic flux density is exceedingly small.

Abstract: PROBLEM TO BE SOLVED: To enable identifying a blown-out fuse accurately and replacing it with a good one by parallel-connecting to the fuse a detecting section comprising an electric light-emitting body and an electric resistor in a series connection. SOLUTION: A detecting section 4 consists of an electric light-emitting body 5 comprising a light-emitting diode; and an electric resistor 6 in a seri connection and is mounted between a pair of through-holes, formed in a printed circuit board. The terminal body sections and connecting sections of junction terminals 9 are inserted into installation holes and the through-holes in the printed circuit board and secured by soldering or laser welding. Thereby the junction terminals 9 are installed on the printed circuit board. A fuse 3 is installed at the mounting section of the junction terminals 9, and thereby the detecting sections 4, comprising the electric light-emitting body 5 and the electric resistor 6, are parallel- connected.  If overcurrent is passed through the electric circuit 2 due to short circuit or the like, therefore, one of the fuses 3 is blown and the corresponding electric light-emitting body 5 emits light. As a result, the blown fuse can be easily and accurately identified with a visual check.

Title: Molding method of photographic film cartridge cap
Inventor: WATANABE KENJI
IPC: G03C3/00
Filed: 1995-09-22
Abstract: PROBLEM TO BE SOLVED: To prevent the shaving of a spool due to burrs by making the maintenance of punch and die easy and simple. SOLUTION: When an opening rim 13 is formed by punching in a molding process for a cap, the die 30 is pressed against the opening rim 13 from the rear side of a steel sheet 20. The die 30 is constituted in such a manner that a pressing part 32 having a flat pressing surface 32a and a fitting part 33 in the shape of a truncated cone are laminated. The front surface 33a of the fitting part 33 is formed a little smaller in diameter than the punching diameter of the opening rim 13. When the die 30 comes into contact with the opening rim 13, the fitting part 33 is inserted in the opening rim 13 and the edge part 14 of the opening rim 13 comes into contact with the periphery 33b of the fitting part 33.  When the die 30 is pressed until the pressing surface 32a is brought into close contact with the rear surface of the steel sheet 20, the edge part 14 of the opening rim 13 is crushed by the periphery 33b of the fitting part 33. Further, when the burrs are generated in the edge part 14, it is crushed together with the burrs. Thus, the friction between the outer periphery of the spool and the edge part 14 is prevented, and the shaving of the spool is prevented.

Filed: 1986-10-17
Abstract: PURPOSE:To prevent the damage of an image carrier at the time of replacing or taking out a developing device by moving the developing device to a position separated from the image carrier at each time of a series of image forming operations. CONSTITUTION:A developing device 2 can be moved between the developing position, where the developing device approaches an image carrier 1 to develop a latent image on the image carrier, and the development unoperating position where the developing device is separated from the image carrier 1 and does not develop the latent image. That is, the developing device 2 is moved to the developing position by a developing device driving cam means 6 rotated around a shaft 6a, and the pressing force of the developing device driving cam means 6 is released and the developing device is pulled away from the image carrier to move the developing device to the development unoperating position. Consequently, the developing device 2 is set to the developing position near the image carrier only at the time of developing operation and is drawn back to the development unoperating position after the developing operation. Thus, the developing device 2 is led out to the front and is easily taken out of a device body without contacting with the image carrier 1.
