Title: Combustion state detector for internal combustion engine
Inventor: INAGAKI HIROSHI
IPC: F02P17/00
Filed: 1995-06-13
Abstract: PURPOSE: To obtain a combustion state detector which can detect the combustion state of an internal combustion engine accurately at all times while reducing the size and cost easily. CONSTITUTION: After spark discharge of each cylinder, a high voltage pulse is applied to the ignition system through a reverse current prevention diode D1 and a leak prevention diode D2 thus charging the ignition system. Subsequently, the diodes D1, D2 are connected through a shield wire 30 in a combustion state detector for detecting the combustion state of each cylinder based on the variation of voltage when the ignition system is discharged through ions existing around the electrode of an ignition plug 10. Voltage variation after application of high voltage pulse is detected based on the voltage across a capacitor C1 having one end connected with the outer electrode of the shield wire 30 and the other earthed end. With such arrangement, capacitance of the high voltage pulse applying path with respect to the earth can be prevented from varying due to the environment.  Furthermore, size and cost can be reduced by eliminating a high withstand voltage, small capacity capacitor for voltage detection.

Title: Bus priority controller
Inventor: AOKI TAKASHI
IPC: G06F13/362
Filed: 1981-09-17
Abstract: PURPOSE:To shorten a bus priority decision time by dividing modules connected to a bus into plural blocks, and connecting modules in each block in series and those blocks in parallel. CONSTITUTION:When a signal REQ1 from a module 3a and a signal REQ3 from a block 3j are inputted as a bus request to a priority deciding circuit 3m, a signal ACK3 which corresponds to the signal REQ3 with higher priority is outputted to the terminal ACK of a module 3d. When modules 3e and 3f generate bus requests, the signal inputted to the terminal ACK of the module 3d is outputted, as it is, from the terminal OUT and inputted to the terminal ACK of the module 3e. Since the signal logical level at the terminal REQ of the module 3e is 1, the module 3e is connected to the bus and the signal at the terminal OUT of the module 3e has logic 0, inhibiting access from the module 3f to the  bus.
