Title: Component jam removing method at vibration component transporter
Inventor: AKAMA MASARU
IPC: B65G27/32
Filed: 1988-11-21
Abstract: PURPOSE:To dissolve a component jam simply and surely when the component jam has been inspected by means of an inspection means, by changing vibration so that the component may be transported in the reverse direction. CONSTITUTION:When a component jam occurs, and the flow of components stops at a component overflow detection and component jam detection device Q, a light receiving element 28 keeps on receiving the light of a light emitting element 27. As soon as a control circuit 29 inspects this condition, a transfer direction reversing output S is generated from an input terminal 61, and supplied to a drive circuit which is not shown in the drawing. As a result, a changeover switch which is not shown in the drawing, is changed over, and the vibration direction of the track of a ball 2 is changed over to the reverse direction of the present transfer direction. Accordingly, the component is moved from a jammed place to the reverse direction, and jamming is dissolved. The detection signal ceases to exist as jamming is dissolved, and the transfer reversing output S ceases to exist after the lapse of a predetermined time, and a normal operation is returned. As a result, jamming is dissolved simply and surely.

Title: Measuring instrument for sensitivity of photosensitive body
Inventor: HISATOMI SHINICHI
IPC: G03G21/00
Filed: 1985-12-25
Abstract: PURPOSE:To shorten a measurement time by comparing the output value of a surface potential detecting device with the 1st and the 2nd specific values, and decreasing the quantity of electrostatic charging of a photosensitive body gradually and measuring the sensitivity of the photosensitive body during the period from the 1st comparing means output to the 2nd comparing means output. CONSTITUTION:The output of a surface electrometer 5 drops from the 1st specific value V1 so that the photosensitive body 1 starts optical attenuation with light from a light source 9. When the output of the surface electrometer 5 reaches the 2nd specific value V2 which is the set voltage of the 2nd comparator 13, the output of the 2nd comparator 13 is inverted from a high level to a low level and this low-level signal is outputted to a controller 14. The controller 14 clocks the time T from the detection of the 1st specific value V1 by the 1st comparator 12 to the 2nd specific value V2 by the 2nd comparator 13. The time T is the attenuation time within the specific range of the surface potential of the photosensitive body 1, so the time T is proportional to the sensitivity S. Consequently, the sensitivity of the photosensitive body can be measured and the time required for the measurement is short.
