Title: Air-fuel ratio controlling apparatus for internal- combustion engine
Inventor: MORITA TATSUROU
IPC: F02D41/14
Filed: 1982-12-21
Abstract: PURPOSE:To lower the specific fuel consumption of an internal-combustion engine, by providing a means for measuring the crank angle position at which the pressure in a cylinder becomes maximum and a fuel injection means for controlling the fuel supply rate according to the number of cylinders and the engine speed in a specific range. CONSTITUTION:Pressure detectors 23-26 detect the pressure in respective cylinders. An arithmetic circuit 30 reads out data relating to the pressure in each cylinder which is stored in a memory-A 29 and measures the crank angle position Qmax at which the pressure is the cylinder becomes maximum. In the memory-A 29, the crank angle position Qmax is compared with a reference value. In case that the crank angle position Qmax comes out of a prescribed range, a memory-B 31 increases the count of a counter by one step. Further, an arithmetic circuit 35 calculates the datum injection quantity from the outputs of an air-flow meter 15 and an engine-speed detector 33 and corrects the datum injection quantity on the basis of the data stored in the memory-B 31. With such an arrangement, it is enabled to keep stable combustion of an engine and to thereby lower the specific fuel consumption.

Title: Frame transmission system
Inventor: ABE YOSHIHIKO
IPC: H04L1/00
Filed: 1986-09-20
Abstract: PURPOSE:To decrease an information from a primary station from being abolished at a secondary station when busy state takes place continuously in the secondary station by revising a consecutive transmission frame number of the primary station dynamically depending on a received affirmative frame number of the secondary station. CONSTITUTION:A transmission processing section 4 uses a value set in a transmission frame number register 2 to decide a consecutive transmission frame number, a sequence number sent to each frame is added to send the result to the secondary station. The busy state takes place in the secondary station to a frame group sent by the primary station and only a part is taken as the reception affirmative state. In such a case, the transmission number is counted by a transmission number counter N in the transmission processing section 4 and the transmission is repeated till the preset value (n-1) times. When the count of the counter N reaches (n), the consecutive transmission frame number S is incremented to a value R of a reception affirmative frame number register 3 from the initial setting value I by 1. When the state of the secondary station is unchanged, the operation is repeated. That is, one frame is abolished by the secondary station, but number of abolished frames is less than that sent by the initial setting value.
