Filed: 1979-01-16
Abstract: PURPOSE: To reduce the number of logical elements, needed for an N-key lockout function, as mamy as possible by providing three D-type FFs and by making use of delay characteristics of those FFs.  
     CONSTITUTION: Synchronizing with outputs QAWQD of counter 4, key switches K 00 WK 33  of matrix circuit 1 are scanned by multiplexer MX2 and decoder 3 to output logic outputs of key switches from MX2 in sequence. The output of MX2 is inputted to clock terminals CK of FF7 and FF8 by way of gate 6. When all key switches are scanned once, FF7 and FF8 are reset by a cyclic end signal, and output Q of FF7 and output Q' of FF8 are reset to levels "L" and "H" respectively. Then FF8 reads output Q of FF7 before rising by a 1st key-push signal while FF10 is not cleared, and after the period end, a strobe signal is sent out. With a key pushed not less than twice in a single period, the strobe signal is inhibited at the point in time when the key is depressed secondary, so that the N-key lockout function can be attained.

Title: Device for controlling air-fuel ratio of engine
Inventor: NAKAGAWA TOYOAKI
IPC: F02D41/14
Filed: 1989-01-11
Abstract: PURPOSE:To rapidly correct an air-fuel ratio to be a target air-fuel ratio by calculating the differential value of the control reversing period ot air-fuel ratio proportional-plus-integral control, and increasing the proportional amount or integral amount when the value thereof is positive while reducing same when the value is negative. CONSTITUTION:A calculating means 2 calculates a basic fuel injection quantity based on an engine operating condition detected by a detecting means 1. On the other hand, an air-fuel ratio control means 4 carries out the feedback correction of the basic fuel injection quantity by means of proportional-plus-integral control in accordance with the deviation between the detected value of air-fuel ratio by a detecting means 3 and a target air-fuel ratio. In this case, the differential value of the control reversing period of the proportional-plus-integral control is calculated by a calculating means 5, to carry out correction so as to increase the proportional amount or integral amount of the proportional-plus-integral control when the differential value is positive while reducing same when the value is negative. Thereby, even if air-fuel ratio is varied due to an external condition, the air-fuel ratio can be rapidly corrected to be the target air-fuel ratio to ensure a favorable emission of exhaust gas.

IPC: G06F11/34
Filed: 1988-01-12
Abstract: PURPOSE:To detect and analyze a fault factor in real time by securing such constitution where an IOC controller which detected the working abnormality of an I/O controller activates a forced interruption signal and transferring the contents of control tables and trace memories to the I/O controller to dumping these contents on an external terminal. CONSTITUTION:An IOC controller 7 that detected the working abnormality of I/O controllers 61 and 62 activates the forced interruption signals put on the signal lines 41 and 42 and gives an instruction to both controllers 61 and 62 to transfer the contents of control tables 11 and 12 and trace memories 21 and 22 respectively. When the forced interruption signals are received, the controllers 61 and 62 transfer the contents of said tables 11 and 12 and memories 21 and 22 to a fault memory 3 of the controller 7. These contents collected into the memory 3 are always dumped as necessary on an external terminal 8 via a diagnosis bus signal line 5 in the form of fault information. Thus the fault factor can be detected and analyzed in real time.

Title: Satellite communication system
Inventor: SAKAI TOSHIKI
IPC: H04L12/28
Filed: 1993-01-13
Abstract: PURPOSE:To prevent the degradation of throughput due to repeated resending of a packet by raising the transmission power in each slave station at the time when the frequency in resending of data transmitted to a master station exceeds a prescribed threshold and prefentially receiving reception data having a higher signal intensity by the master station. CONSTITUTION:Slave stations 1, 2, and 3 receive the occurrence of data to transmit data synchronously with each other so that a transmission packet ts is inserted. Though packets B and C collide with each other and are resent after the lapse of an arbitrary time, the packet B is sent as a packet B' after the rise of the transmission power when the frequency in resending of the packet B exceeds a preliminarily determined threshold. This packet B' collides with a packet A' but is correctly received by the master station since signal intensity is large. Packets A' and C are resent as packets A'' and C' after the lapse of the arbitrary waiting time and are correctly received without collision.
