Abstract: PURPOSE:To reduce exhaust gas and at the same time improve fuel consumption and an operation performance by setting beforehand at a correction map an ignition time correction value determined by cooling water temperature and air intake temperature, calculating an ignition time by adding this ignition time correction value to a reference ignition time. CONSTITUTION:During engine operation, at a control means 112, a reference ignition time is calculated by using a reference ignition time map and from an engine rotation number by means of a crank angle sensor in a distributor 116 and air intake pressure by means of a pressure sensor 86. Also, on the basis of the outputs of a water temperature sensor 102 and an air intake temperature sensor 104, an ignition time correction value is calculated by using an ignition time correction value map in which it is arranged that an ignition time spork retard amount is reduced as air intake temperature rises and an ignition time is spark-advanced at more than a predetermined air intake temperature. And the final ignition time is calculated by adding this ignition time correction value to the reference ignition time, and the operation control of an ignition mechanism 114 is conducted. As a result, the optimum ignition time in accordance with cooling water temperature and air intake temperature is provided.

Title: Cleaning device of electrophotographic copying machine
Inventor: ICHIKAWA HIDEO
IPC: G03G21/00
Filed: 1983-08-29
Abstract: PURPOSE:To prevent toner containing foreign matter such as paper powder from sticking to a cleaning blade, and prevent the deterioration in the performance of the blade by providing a mechanism which separates the cleaning blade from a photosensitive body when the photosensitive body reverses. CONSTITUTION:The photosensitive body reverses by receiving a signal from a main motor reversing circuit 13 after a cleaning operation, and a device stop signal is inputted to a solenoid control circuit 14 simultaneously; and a support member 10 rotates around a shaft 11 by receiving counterclockwise force through the operation of a solenoid 4 and the blade 2 leaves the surface of the photosensitive body 1. At this time, the toner collected with the blade 2 falls as it is or remains while sticking to the photosensitive body 1, and consequently the toner containing foreign matter such as paper powder does not lump by flowing round to the edge of the blade 2. Consequently, the blade 2 is not in contact with the photosensitive body 1 in the reversing operation, so no unreasonable force is applied from the photosensitive body 1, thereby eliminating deflection.
