Title: Method, device and system for detecting life of cartridge, and cartridge and storage medium
Inventor: ITO YOSHIHIRO
IPC: G03G15/08
Filed: 1999-10-12
Abstract: PROBLEM TO BE SOLVED: To detect the life of a cartridge. SOLUTION: This cartridge is provided with a photoreceptor drum, a developing roller, a charging roller and toner chamber filler with toner. The cartridge is also provided with a revolution detecting part for detecting the revolution of the photoreceptor drum. A cartridge CPU obtains the cumulative value of the number of revolution of the cartridge and writes the value in a cartridge memory in the middle of using the cartridge. At the time of loading the cartridge to a printer main body, the cumulative value written in the cartridge memory is read. When the cumulative value amounts to a prescribed value or over, the cartridge is judged to be inappropriate because it is used to its limit of life. Then, a warning is displayed and printing is prohibited. In using the cartridge, where the cumulative value has not amounted to the prescribed value yet, printing is normally executed.  At the time of the cumulative value amounting to the prescribed value during normal printing, the warning is displayed.

Title: Zoom lens
Inventor: IKEMORI KEIJI
IPC: G02B15/20
Filed: 1989-11-08
Abstract: PURPOSE:To reduce the overall size of the lens and to obtain excellent optical performance over the entire variable magnification range by specifying the refracting power and lens constitution of three lens groups. CONSTITUTION:The zoom lens consists of three lens groups I-III which are negative, positive and negative in refracting power in order from the object side, a method which compensates chromatic aberrations in the respective groups is not employed, and the aberrations of the three lens groups I-III cancel one another so that the chromatic aberration of the whole lens system is compensated with good balance. Consequently, even when each lens group consists of one or two lenses to shorten the overall length of the lens, various aberrations can be compensated including the chromatic aberrations with good balance, so that the zoom lens with high optical performance is obtained.

IPC: H01L21/3205
Filed: 1987-11-18
Abstract: PURPOSE:To make it possible to obtain good superconductive characteristics which are stable for a long period by forming a superconductor on a substrate which is less permeable to oxygen, and covering it with a film which is less permeable to oxygen. CONSTITUTION:A silicon nitride film 11 and a silicon nitride film 12 enclosing a superconductive oxide wiring 13 are installed on a silicon substrate 10, where the superconductive oxide wiring 13 is a thin film consisting of Y Ba2 Cu5 Ox (x=5-7), for example. The silicon nitride film 11 prevents diffusion of impurities from the silicon substrate 10 to the superconductive thin film 13, and the silicon nitride films 11, 12 prevent the outward diffusion of oxygen from the superconductive thin film 13 at the time of heat processing, so there is almost no exchange of oxygen between the superconductive oxide wiring 13 and the external. By thus enclosing the superconductive oxide thin film 13 with films which are less permeable to oxygen, change of composition of the superconductive oxide thin film 13 can be prevented during processes or after formation of a device, thereby good superconductive characteristics which are stable for a long period can be obtained.

Abstract: PURPOSE:To attain fast feeding for a short time finish regardless of the type of material of a magnetic tape by providing 1st and 2nd running paths, selecting the path optionally in response to the load state of a winding reel base and revising a speed reference voltage. CONSTITUTION:A motor driving current of a motor driving circuit 17 is inputted to a motor driving current detection circuit 18 so as to discriminate whether or not the motor current exceeds a predetermined value for a prescribed period or over. When the current exceeds the value, an output of the circuit 18 is inputted to a system control circuit 19 to allow the circuit 17 to stop the drive of a tape 1 and controls a motor driving circuit 20 to stop the operation of a loading motor 21. As a result, the position of loading posts 4, 6 of the 1st running path for the tape 1 is revised into the position of loading posts 4', 6' of the 2nd running path. When the 2nd running path is selected, the speed reference voltage from a speed reference voltage generating circuit 15' is revised by a command from the circuit 19 to select the tape speed for the 2nd running path to a higher speed.

Abstract: PURPOSE:To easily and surely realize a satisfactory image formation spot shape by bringing a luminous flux from a collimating part to image formation linearly on the surface being afocal on the deflection surface, and also, being orthogonal to the deflection surface by a first image forming optical system, and condensing a luminous flux from a deflector onto the surface to be scanned by a second image forming optical system. CONSTITUTION:The first image forming optical system 2 is afocal on the deflection surface, therefore, two pieces of spherical lenses 2a, 2c constitute a beam expander system on the deflection surface. Accordingly, by setting a beam expansion ratio of this beam expander system in accordance with spot width in the main scanning direction, desired spot width can be designed. Also, the first image forming optical system has cylindrical lenses 2b1, 2b2, and these lenses 2b1, 2b2 have power in the direction being orthogonal to the deflection surface, therefore, by displacing these lenses 2b1, 2b2 in the optical axis direction, the spot width can be adjusted in the sub-scanning direction. In such a way, a desired image formation spot shape can be realized easily and surely.
