Title: Valve timing control device for internal combustion engine
Inventor: MORI TAIICHI
IPC: F02D41/04
Filed: 1993-06-04
Abstract: PURPOSE:To expedite atomization of fuel to improve combustibility by setting a valve overlapping quantity at a large value in correspondence with increasing quantity of fuel injection during a cold state of an engine. CONSTITUTION:The device is provided with a variable valve timing mechanism (VVT) 23, an intake air temperature sensor 34 for detecting intake air temperature, and a VVTECU 41 for driving-controlling the VVT 23 based on a detection result of the intake air temperature sensor 34. An engine ECU 40 increasingly corrects fuel injection in a cold state based on the detection result of the intake air temperature sensor 34. Until the intake air temperature after starting in the cold state reaches the specified temperature, an advance angle increasing correction value corresponding to the intake air temperature is set by the VVTECU 41. A control region of the VVT 23 is changed by the VVTECU 41 so that this advance angle increasing correction value is added to a basic advance angle quantity to increase variable width of valve overlapping.

Title: Temperature controller for fixing unit
Inventor: NAKAMURA YUTAKA
IPC: G05D23/00
Filed: 1991-06-07
Abstract: PURPOSE:To prolong the life of a switching means such as a triode AC switch by reducing the number of ON/OFF switching times for the energization of a heater. CONSTITUTION:Plural timers having different setting times are set to a RAM 4b, and the temp. detecting data of a thermister TH outputted via an A/D converter 3 is compared with the data of a threshold set to a MPU 4 in advance.
