Title: Control device for revorutional number of gasoline engine
Inventor: UCHIYAMA TADASHI
IPC: F02D41/00
Filed: 1983-10-29
Abstract: PURPOSE:To prevent the fluctuation of the revolutional number of an engine in idling even when the electrical load changes by controlling the open/close time of an air bypass according to the electrical load detected by an electrical load detecting device. CONSTITUTION:An electrical load 350 consisting of a room cooler, head lights, etc. is detected by use of a current detecting resistance 107 which is connected in series with a field coil 103. The larger the load becomes, the longer the open time of an electromagnetic valve 901 is made. In this way, the amount of air can be increased in accordance with the electrical load; therefore, the revolutional number of the engine in idling can be maintained constant regardless of changes in the electrical load.

Title: Sector identification system
Inventor: MORI TATSUMI
IPC: G06F3/06
Filed: 1993-08-19
Abstract: PURPOSE:To provide a sector identification system in which the presence or absence of a sector can be checked without using a memory on a system by using a result status from a controller. CONSTITUTION:A DMA channel for transfer is set in a transfer invalidating state (step 101). Next. the sector is read (step 103). The presence or absence of a transfer system error is judged from the result status from an FDC at that time (step 105). When the sector is present, the FDC tries to transfer a data part read from a medium to a CPU. However, when the DMA is disable, the FDC recognizes the DMA suppression, and communicates a transfer system error through a BUSC to a CPU 11. Thus, when the transfer system error is judged in the step 105, the CPU judges that the sector is present (step 106).

IPC: H04N1/393
Filed: 1989-08-07
Abstract: PURPOSE:To prevent a lateral line from being displayed on a magnified picture by selecting 3 areas or over for a storage section so that the write and the readout in the storage section do not access a same address. CONSTITUTION:A memory 15 is formed to store video information of 3 patterns and write/readout of video information in a magnified range are implemented simultaneously.
