Title: Fail-safe processing method in valve timing changeover control of internal combustion engine
Inventor: SEKI YASUHIRO
IPC: F02D43/00
Filed: 1988-10-11
Abstract: PURPOSE:To enable air-fuel ratio to be properly controlled by changing over the valve timing to a low-speed valve timing when an abnormality in an engine control system is detected, and also by carrying out fuel supply based on the basic fuel quantity at the time of high-speed valve timing when the engine speed is higher than a prescribed engine speed. CONSTITUTION:A driving circuit 21 for controlling a fuel injection valve 6 and an ignition plug 22,and a solenoid valve 23 for carrying out the valve-timing changeover control of intake/exhaust valves are controlled by an ECU 5. The valve timing is enabled to be freely changed over to a low-speed valve timing or to a high-speed valve timing, and a valve-timing changeover command signal is output at the time when the basic fuel quantity set at a low-speed valve timing takes nearly the same value as that set at a high-speed valve timing. In this case, when an abnormality in the control system of an internal combustion engine 1 is detected, a valve-timing changeover command signal is output so as to change over the valve timing to a low-speed valve timing. When the engine speed in that time is higher than a prescribed engine speed, the fuel ignition valve 6 is controlled on the basis of the basic fuel quantity set at the high-speed valve timing.

IPC: G06F3/14
Filed: 1994-09-27
Abstract: PURPOSE: To improve the operability without requiring a large manipulated variable by temporarily breaking off the proportional relation between the manipulated variable and cursor movement quantity of a cursor controller and moving a cursor apparently discontinuously, i.e., making a skip. CONSTITUTION: To skip a cursor position 12 to fixed positions 13-16 on a screen 11 with operation switches 22-25, a cursor origin 17 is fixed on the screen 11 and the cursor is moved temporarily to the cursor origin 17 and then moved to the respective fixed positions 13-16 since the cursor controller, namely, a mouse 20 can control only the relative position relation of the cursor. Consequently, even when the cursor is moved large by being skipped, no large manipulated variable is required. The cursor position control method with good operability is obtained.

Filed: 1988-10-12
Abstract: PURPOSE:To prevent the generation of cracks and enhance the efficiency of heat exchange by installing a plurality of box-shaped heat exchanger so that they may face each other with a space provided between said exchangers, using the space as an air duct, and laying out a combustion chamber and a connection pipe in the outlet of said air duct. CONSTITUTION:The indoor air which is sucked up from an indoor air intake port 7 by a blower 3 during heating operation, is discharged indoors as a hot air from a blow-off port 6 after it has heat-exchanged in heat exchangers 21 and 22, a connection pipe 8, a communication pipe 10, and a combustion chamber 1. The flames in the combustion chamber 1 are attracted to the connection pipe 8 so that the A1 side of the wall may be subjected to the highest temperature out of the walls of the combus tion chamber 1. However, the combustion chamber 1 and the connection pipe 8 are laid out in the outlet of air in the space between the heat exchangers 21 and 22, which reduces the temperature and heat-exchanges to satisfactory extent. Therefore, the generation of cracks induced by high temperature can be eliminated while the efficiency of heat exchange can be improved. Furthermore, the efficiency of heat exchange can be improved by designing the shape of an air inlet between the heat exchangers or an air guide plate so that they may have a fixed throttle angle 9.

Filed: 1988-10-14
Abstract: PURPOSE:To obtain a high-speed memory device having a large capacity at a low cost with no use of a buffer memory by using a memory consisting of a dynamic element having a static column mode. CONSTITUTION:When a working register 3 is set in a static column mode, a CPU 7 starts a memory cycle. In a memory cycle section, a row address is latched by a latch 5 and at the same time a memory selection signal 23 is produced by a decoder 9. Receiving the signal 23, a memory control part 2 outputs successively a RAS signal 28, a switch signal 27 of a selector 8, and a CS signal 29 respectively. Thus the CPU 7 can acquire the desired read data from a memory 1. Then the CPU 7 starts the next memory cycle and a comparator 6 compares the address signal received from the CPU 7 with the address latched by the latch 5. When the coincidence is obtained between the address signal and the address, the part 2 supplies continuously various signals to the memory 1.
