Abstract: A process cartridge is detachably mountable to an electrophotographic image forming apparatus main assembly. The main assembly includes a main assembly electrical contact, first and second projections, main assembly positioning portions, and a force application member. The cartridge includes first and second frames, a first-frame drum, first and second portions, a second-frame developing roller, a second-frame force receiving portion, a regulating portion, a first-frame memory, a cartridge electrical contact, and a first-frame recess and a second-frame recess. When the cartridge is set in the main assembly, the cartridge electrical contact moves integrally with the main assembly electrical contact by the first frame recess engaging the first main assembly projection and the second frame recess engaging the second main assembly projection, upon the first frame rotating about the first portion and the second portion by the force receiving portion receiving the force from the force application member.

Abstract: An iris authentication apparatus includes a camera for obtaining the image of an eye; a display panel arranged on the same plane as where the lens of the camera is arranged; and guide character generation means, wherein a guide character is displayed on a display panel, and the eye of a person to be authenticated who watches the guide character is guided. As a result, a satisfactory iris image can be obtained by the iris authentication apparatus of one camera type that does not have a zooming function, so that the iris authentication apparatus that can be mounted to a small body, such as a portable telephone, can be provided.

Abstract: A reactance of a reactance element in a multi-layer circuit board apparatus is trimmed by cutting a portion of the circuit pattern of the reactance element with a laser beam. The reactance element is sandwiched between grounded layers. A coil circuit pattern having at least a hole therein may be provided as the reactance element. A side portion between the edge of the coil circuit pattern and the hole is cut with the laser beam to trim the inductive reactance. Cutting is effected while the circuit is operated and the operating condition such as an oscillation frequency is observed. A plurality of holes may be provided in the coil circuit pattern. The trimming amount of the inductive reactance is determined by the number of the hole subjected to cutting. The holes may have different sizes. The trimming amount is obtained by which one of the hole is subjected to cutting. The distance between the cut circuit pattern is equal to or larger than the thickness of the circuit pattern.

Abstract: In a conventional color printer, especially an in-line type full color image forming apparatus, an aberration of optical axes caused by distortions of structures affect a performance of an image forming as a tilt aberration in a printed image. Accordingly, in a conventional color printer, distortions have to be prevented by strengthening rigidity of machine structures or parts of the machine. However, fine adjustment or assembling to strengthen rigidity generally causes an increase in cost and requires time-consuming adjustment. An apparatus in the present invention provides advantages of high accuracy and strengthened structure without increasing cost.

Abstract: A method and apparatus is provided for shaping elongated bar-shaped bread dough pieces. In and by this method and apparatus a bread dough piece, namely, a bread dough sheet, a divided bread dough mass, or a preshaped bread dough roll, is subjected to a first rotation, thereby pressing and rolling it in a first gap defined by a conveyor and a pressing belt or a pressing board that faces it, while being conveyed downstream, so as to shape an elongated bar-shaped bread dough piece. This elongated bar-shaped bread dough piece is then fed into a second gap defined by an upper face that comprises a pressing belt or pressing board and a lower face that faces it and comprises a conveyor, a pressing belt or a pressing board, and is subjected to a second rotation that is in a direction reverse to that of the first rotation, thereby shaping a further elongated bar-shaped bread dough piece with a straight wound-dough end.
