Filed: 1983-10-20
Abstract: PURPOSE:To smoothly operate an engine, by changing two engine operation parameters for each other to use one of them when the engine is shifted to a low-load operation from another operation. CONSTITUTION:A throttle valve sensor 17 and an absolute pressure (PBA) sensor 12 are provided so that these two sensors are used to control an engine when it is shifted from a low-load operation from another operation.

IPC: G06F13/14
Filed: 1986-08-25
Abstract: PURPOSE:To reduce labor for manually controlling and setting a device number to decide a number inherent to a deice in a configuration device based on its information that the CPU reads and to set said number in each configuration device. CONSTITUTION:A device number setting control part 2 takes information on one device out of a configuration information storage part 3, refers to a standard number table and sets the device number of each device. All I/O devices are numbered, and the results are stored in a storage part 4. Upon the completion of storing the device numbers, the control part 2 recognizes whether the ID of the same channel has a duplicated number. If so, the device number of a device with low priority, which a standard device number table shows, is modified and stored in the storage part 4. Such processing is repeatedly executed until the duplication of the device number disappears. Afterwards, the control part 2 allocates subchannels for the unit of the device, stores its number in the storage part 4 on a shape basis, and sets the ID of a channel path connected to a subchannel information block.

Abstract: PURPOSE:To improve the adjustment accuracy of the press-contacting force of a cleaning blade to an image carrier by providing a maintaining means which holds the press-contacting force constant. CONSTITUTION:A blade cleaning device has the blade 2 around a rotatable fulcrum shaft 4 through a blade holder 3, and the blade edge 2a of this blade 2 is arranged in contact with the surface of a photosensitive drum 1.

Title: Watch dog timer prohibiting circuit
Inventor: KIRISAWA AKIHIRO
IPC: G06F11/30
Filed: 1988-08-08
Abstract: PURPOSE:To prohibit watch dog and effectively activate the power-on reset of a watch dog timer and power source voltage monitoring function by providing a watch dog prohibition and allowance changing-over switch to prohibit the operation of the watch dog timer. CONSTITUTION:The prohibition of the watch dog is executed by adding the ALE signal of a CPU 1 to a clock input terminal CK of a watch dog timer 2. In such operation, instead of the retrigger of the watch dog timer 2 by a program, hardware-like retrigger is executed by using a signal which is periodically outputted form the CPU 1. Accordingly, since reset is executed in the case that abnormality is generated in the CPU 1 and a CPU control signal is interrupted by some causes, the CPU 1 can normally continue operation without integrating the retrigger routine of the watch dog time for the program.
