Abstract: PURPOSE:To reduce the variation of the ignition timing by estimation-processing the ignition timing according to the cycle measurement data at the preceding time when the engine revolution speed is over a prescribed value, while according to the cycle measurement data at this time when the engine revolution speed is below the prescribed revolution speed. CONSTITUTION:A CPU 3 measures the cycle by an input timer 4 on the basis of the output signal supplied from a signal coil 1 taken in an input circuit 2, and when the input signal interruption routine is started, the revolution speed is calculated on the basis of the cycle measurement data in the preceding time which is memorized in a RAM 9, and if the revolution speed is less than a prescribed value, the cycle is measured, and the ignition timing estimation treatment by the cycle measurement data at this time is carried out. When the revolution speed is over the prescribed value, the ignition timing estimation treatment by the cycle measurement data in the preceding time which is stored in the RAM 9 is carried out, and the cycle is measured, and the ignition timing is calculated on the basis of the obtained cycle. Thus, the ignition timing estimation time can be reduced, and the variation of the ignition timing due to the variation of revolution can be reduced.

Title: Transmission method for optical space propagation data
Inventor: YAMASUDA SHIGERU
IPC: H04W74/08
Filed: 1985-11-07
Abstract: PURPOSE:To set a terminal equipment regardless of the setting situation of a data transmission medium by providing a photo-electric signal converting means to the data transmission medium and the terminal equipment respectively and performing the transmission and reception using optical signals between both signal converting means. CONSTITUTION:When data are transmitted from a terminal equipment 5, the electric signal sent from the equipment 5 is converted into the optical signal by a terminal head 4 and sent to a satellite head 3 by the light emitting function. Then the optical signal is converted again into the electric signal by the head 3 and sent to a transmission medium. In case the optical signals are set to the head 3 from plural heads 4, these signals are superposed on each other to be turned into a superposed signal different from the ordinary transmission/ reception signal. This superposed signal is sent as it is to the head 3 and then to the transmission medium to be turned into the collision signal. Thus the head 3 receives the superposed collision signal and therefore recognizes that a collision occurs in a network. Then the head 3 gives a call call to a communication circuit to transmit signals again after a prescribed period of time.

Filed: 1988-10-04
Abstract: PURPOSE:To use one antenna equipment for transmission as well as reception and to sufficiently attain isolation between them by arranging two kinds of lambda/4 short-circuit type rectangular radiation element which resonate with different frequencies, on one plane. CONSTITUTION:The radio wave supplied to a radiation element 1a from a micro strip line 4 causes a resonance phenomenon with a frequency fr1 determined by its width W1 and length L1. Though a short-circuit 5a is provided in a middle position in the lengthwise direction, namely, the position of L1/2, the similar resonance phenomenon is caused, and it resonates with the frequency fr1. With respect to a radiation element 1b, a resonance phenomenon is caused with a frequency fr2 determined by its width W1 and length L2 in the same manner. Consequently, areas occupied by radiation elements 1a and 1b on a printed board 2 are reduced to a half. Thus, two kinds of radio wave different in frequency are radiated with one plane antenna, and isolation between them is sufficiently attained.
