Abstract: PROBLEM TO BE SOLVED: To delay the deterioration of an image carrier and to prevent an image defect by changing the number of sampling times or a sampling time in the detection of the life of the image carrier in accordance with the service circumstances of the image carrier. SOLUTION: A current is detected by changing the number of sampling times or the sampling time in accordance with the service circumstances of the image carrier, and the life of the image carrier is judged according to the detected current value. In this device, the current flowing between a primary electrifier 228 or a transfer electrifier 239 and a photoreceptor drum 240 functioning as the image carrier is detected before starting to form an image (that is, at the time of pre-multiple rotation) or after forming the specified number of images (that is, at the time of post-rotation). In the case of detecting the current value, the number of sheets of transfer paper passing through the drum 240 is counted and the number of sampling times or the sampling time of the detected current value is controlled in accordance with the counted value.  Then, the life of the drum 240 is judged based on the current value, to which the number of sampling times or the sampling time is controlled.

An A pin 6 is soldered to a conductor of the ceramic package 3 and this conductor is wired to an A terminal 4 in the package 3. At the time of normal operation of a semiconductor, an electrical continuity is obtained between the A terminal 4 and a B terminal 5 and when an element 7 generates heat abnormally and a pressure in the interior of a sealing body is increased, the cap 2 is stretched upward. Accordingly, as the contact of the cap with the A pin 6 is eliminated and a continuity between the A and E terminals 4 and 5 is eliminated, an alarm circuit at an abnormal time can be constituted by whether there is an electrical continuity between the A and B terminals 4 and 5 or not at the time of normal operation and the time of abnormal heat generation.

Title: Synchronizing signal separating and clamping circuit
Inventor: SEKIMOTO KUNIO
IPC: H04N5/18
Filed: 1984-11-15
Abstract: PURPOSE:To attain excellent synchronizing separation and clamping by passing a video signal through an amplifier having a dynamic range where the synchro nizing signal part to be clamped before being fed to a comparator is not suppressed even when a DC potential of the synchronizing signal is fluctuated before the video signal is fed to the comparator.

When the amplifier 4 has a dynamic range lower than F and an input signal changes from a period T1 to a period T2, a correct synchronizing signal does not appear at the output of the comparator 6 and the loop of the amplifier 2 is not operated normally. When the input signal c changes from the period T1 to the period T1, since the circuit 5 clamps the tip of the synchronizing signal because the upper dynamic range of the amplifier 4 is E, the level responds to a level shown in a signal 13 and then normal synchronizing signal is obtained.
