Abstract:
A solder ball mounting apparatus includes a hopper, a mounting head provided at a tip of the hopper, and a pressing pin which is insertable inside the hopper and the mounting head. The mounting head has an inner diameter which restricts movement of solder balls, and when one of the solder balls is supplied to the mounting head through the hopper, the pressing pin presses one of the solder balls, thereby mounting the solder balls one by one on a target member.
Abstract:
Disclosed is an image forming apparatus, which makes it possible to appropriately conduct a controlling operation for eliminating the velocity fluctuation of the photoreceptor drum without generating any malfunction. The apparatus includes a photoreceptor member driven by a motor and a control section that is provided with a feed forward controlling section that stores parameters derived from driving errors for one revolution of the photoreceptor member to create a reverse-phase instruction value based on the parameters and a feedback controlling section that controls a velocity of the photoreceptor member, so as to keep the velocity of the photoreceptor member constant. During an initial operating time, the control section deactivates the feed forward controlling section, while only activates the feedback controlling section to drive the photoreceptor member so as to measure a driving toque of the driving motor, and selects a parameter from the parameters, corresponding to the driving toque measured.
Abstract:
A resin window includes a plate-shaped main body portion and a gear projection portion that is molded integrally with the main body portion so as to project in a thickness direction of the main body portion from a rear end portion of the main body portion. A part of a side face of the gear projection portion is surrounded by a gear-side guide frame for guiding the raising/lowering of the resin window. The gear projection portion includes a meshing gear provided along a vertical direction to mesh with a drive gear, and positioning members provided respectively on upper and lower end portions of the gear projection portion to abut on an inside surface of the gear-side guide frame. When the drive gear is rotated, the positioning members slide relative to the inside surface of the gear-side guide frame, and thus the resin window can be raised or lowered along the gear-side guide frame.

Abstract:
A battery pack includes: a cell assembly including a plurality of parallel arranged cells that are connected to each other through lead pieces; a planar terminal plate having positive and negative output terminals; and an outer case for accommodating the cell assembly, having one open end at which the terminal plate is arranged. In this battery pack, the outer case is a square tubular metal can with a bottom, the open end edge of the metal can is bent inwards to crimp seal the case with the terminal plate, and one or more apertures are formed in a side face of the metal can. This battery pack has improved battery performance and reduced cost due to increased inner volume of cells and reduced number of components. Furthermore, the battery pack secures high safety even in the event of a release of contents from cells.
