摘要： A method manufactures a head suspension for a disk drive. The method includes a first step of forming a semi-finished suspension (55) having a base plate (37), a rigid part (27) solidly joined with the base plate through a bridge (57), and a positioning hole (63) formed through the bridge. This positioning hole is aligned with a positioning hole (51) formed through part of a flexure (41). A second step of the method fixes a resilient material (31) to the base plate and rigid part of the semi-finished suspension so that the base plate may resiliently support the rigid part through the resilient material. A third step of the method aligns the positioning hole of the flexure with the positioning hole of the bridge and fixes the flexure to the rigid part. A fourth step of the method cuts off the positioning-hole-formed part of the flexure and the bridge including the positioning hole. This suspension is compact and the load beam and flexure thereof are correctly positioned to secure balance.

摘要： An image density control method for an image forming apparatus for forming a plurality of exclusive patterns on a photoconductive element, or image carrier, and controlling an image forming condition based on the exclusive patterns so as to control image density. The exclusive patterns include a high density black pattern and a low density white pattern. While a scanner included in the apparatus is brought to and held at a predetermined position, a latent image of the low densit white pattern is electrostatically formed on the photoconductive element. While the scanner is in a reciprocating motion, a latent image of the high density black pattern is formed on the photoconductive element. The plurality of patterns formed on the photoconductive element are sensed to correct toner density and background output based on sensed values, whereby accurate image density control is promoted.

摘要： A head suspension for a disk drive has a load beam, a base plate, and a recess. The base plate has a thin flange and is capable of improving the attaching accuracy and strength of the head suspension to a carriage arm of the disk drive. The base plate has the flange and a boss. The flange has a contact face to be attached to a contact face of the carriage arm. The boss is inserted into a hole of the carriage arm and plastically deformed therein to fix the base plate to the carriage arm. The load beam has a rigid part and a resilient part and is supported by the base plate, to apply load on a slider arranged at a front end of the load beam. The recess is formed on the base plate along a corner between the flange and the boss, to secure a gap relative to the contact face of the carriage arm.

摘要： An electrophotographic copier, facsimile machine, laser printer or similar image forming apparatus having a photoconductive element. The apparatus corrects a bias voltage for development, amount of charge, amount of exposure or similar image forming factor on the basis of an inactive state of the photoconductive element. When the duration of the inactive state is short and does not need a correction of the image forming factor, an image forming procedure is executed immediately. When the inactive state has lasted a long time, the image forming factor is corrected before the start of an image forming procedure.

摘要： A suspension for disc drive comprises a base plate, a load beam attached to the base plate, and a flexure attached to the load beam. The load beam includes a rigid body portion, formed of a thick plate independent of the base plate, and a spring portion, formed of a spring member in the form of a thin sheet independent of the rigid body portion. The spring member connects the rigid body portion and the base plate. The spring member is thinner than the rigid body portion and has a lower spring constant. The spring portion is more flexible than the rigid body portion.
