Title: Vibrator
Inventor: NAGASAWA HIDEYUKI
IPC: B65G47/14
Filed: 1986-04-11
Abstract: PURPOSE:To facilitate the adjustment of frequency of vibration of a feed device, in a part feeder vibrator, by controlling the frequency and vibrating condition of the feed device in accordance with the frequency and waveform of vibration of a drive device. CONSTITUTION:When an output from a saw blade shape oscillator 14 which may vary the duty-cycle and frequency thereof is applied to a drive coil 12 through an amplifier 15 having a large damping factor, a roller is driven so that it rotates in a high accelerating condition in the rise part of a waveform of the output. Accordingly, a workpiece on a bawl may not follow the rotation of the bawl 1, and therefore, it comes to a stop at that position. Then, in the dropping part of the waveform, although the roller 3 tends to make reverse rotation, the roller 3 is subjected to the magnetic brake action of a magnetic circuit 8 and therefore is returned to its given position. At this time the workpiece may moves together with the bawl 1 since the speed is low. With this arrangement it is possible to facilitate the adjustment of frequency of vibration of the bawl by changing the output of the drive device.

Filed: 1989-04-04
Abstract: PURPOSE:To correctly deal with various kinds of originals and to prevent the occurrence of fogging by selecting two control modes and controlling a development bias output according to the control procedures of a storage means based on the selected control modes. CONSTITUTION:Development bias control procedures stored in a ROM 42 have two modes; one is a continuous AE mode, wherein density information (latent image potential) covering the leading edge to trailing edge of an original is detected to control a development bias based on the sequential information. A latent image formed in an exposure area by an optical system comes to a potential sensor 21 owing to the rotation of a drum-like photosensitive body 15, and latent image potentials are detected at fixed interval as a spot. The detected latent image potential information is inputted to a CPU 40 via an A/D converter 43. The CPU 40 executes calculation to determine a development bias voltage, and its timing is controlled so that when a point to detect the latent image comes to a position facing a developing roll 32a, a development bias voltage corresponding to the position is applied. Thus, the occurrence of fogging is prevented.
