Title: Control device for wait time
Inventor: SOUMA IKUO
IPC: G03G15/11
Filed: 1982-12-27
Abstract: PURPOSE:To make a wait time as short as possible by controlling the same to wait up by a timer means when the formation of images is made possible during rotation. CONSTITUTION:A wait time is controlled by the output signal S2 of the 2nd density detecting circuit. After closing of an electric power source switch, the output signal S2 of the 2nd density detecting circuit is applied to one input of a gate G3. Now when the S2 is ''1'' after closing of the power source, the output of the G3 is ''1'' and is inputted to a gate G4. Since an oscillation signal-OSC is applied to the other one, the output signal MD1 of the G4 is the oscillation signal. Tr1 is driven by said output and a triac Q3 is triggered with a pulse transformer PT1, whereby a motor M1 of a developing device is operated. Then, the wait time is made as short as possible.
Patent JP-H0391721-A (JP)
Title: Active matrix substrate
Inventor: SAITO HISAFUMI
IPC: G02F1/1345
Filed: 1989-09-04
Abstract: PURPOSE:To preclude the penetration of an etchant and to prevent a conductor from being broken by making the part where a gate electrode and a source electrode cross each other and the joined part of a pixel electrode for the drain electrode larger in line width than that of the source electrode and drain elec trode, and coating the end surfaces of the source electrode and drain electrode. CONSTITUTION:The active matrix substrate is so formed that transparent con ductive thin film 7 which is deposited on a source conductor and the line width of the source electrode 5 and drain electrode 6 is larger than that of the source conductor, source electrode 5, and drain electrode 6. Therefore, none of the end surfaces of the source conductor, source electrode 5, and drain electrode 6 is exposed. Consequently, metallic films which form the source conductor, source electrode 5, and drain electrode 6 are never overetched owing to the penetration of the etchant in a process wherein the channel part of a TFT is formed, so the metallic films do not become narrow. Therefore, no conductor breaking is caused at the step part between the pixel electrode 8 and drain electrode 6, the intersection part between the gate electrode 6 and source elec trode 5, etc.
