Title: Electronically controlled fuel injector for internal combustion engine
Inventor: NAGANO MASAMI
IPC: F02D41/02
Filed: 1990-10-17
Abstract: PURPOSE:To improve the exhaust gas performance ranging from the start in cold time to the completion of warming by retarding the fundamental ignition timing according to the temperature of a catalyst and the temperature of an engine. CONSTITUTION:The temperature of exhaust gas lowers when the ignition timing is advanced in comparison with a set value, and on the contrary when the ignition timing is delayed, the temperature rises. The reason comes from the fact that the gas in the cylinder of an engine 7 flows into an exhaust pipe still combusting when the ignition timing is delayed. Accordingly, the temperature rise of a catalyst 20 is accelerated when the combustion gas is introduced into the catalyst 20. Accordingly, the exhaust gas temperature can be raised by delaying-correcting the fundamental ignition timing according to the temperature of a catalyst 20 and the cooling water temperature, and the rise of the temperature of the catalyst 20 can be accelerated. Accordingly, the exhaust gas performance ranging from the start in cold state to warming can be improved.

Title: Frame aligner monitoring system
Inventor: YAMASHITA HIROSHI
IPC: G06F5/12
Filed: 1988-10-31
Abstract: PURPOSE:To monitor the presence/absence of a code error in a signal having no surplus bit in a frame without making a circuit into a large scale by writing each bit of an input digital signal on an elastic memory for every two times, and monitoring the bits by comparing at the time of reading out. CONSTITUTION:The frame pattern of an input frame signal is detected, and synchronism is established at a frame synchronization circuit 1, and write timing of the elastic memory 2 is controlled, and each bit of the input frame signal is written on the elastic memory 2 for every two times with a clock operated at double speed of the bit signal of the input frame signal. Write data is read out, and is compared with data via a shift register 3 at a comparator 4, and the bits written for every two times are compared with each other, then, coincidence/noncoincidence is monitored. Therefore, it is possible to monitor the presence/absence of the code error in the signal having no surplus bit in the frame without requiring a parity signal and making the circuit into the large scale.

Title: Method for deciding attitude of three axis stabilizing satellite
Inventor: OKANUMA TORU
IPC: G01C21/24
Filed: 1992-10-15
Abstract: PURPOSE:To estimate the attitude angle around X, Y, and Z axes and attitude angle speed when the X axis of the three axis stabilizing satellite directed toward the direction of an inertia space apart by the specified angle from the direction of the sun and rotates at an orbital angle speed around the X axis. CONSTITUTION:The attitude angle obtained by integrating the outputs of X, Y, and Z axis angle speed detecting devices 3, 5, 7 is error-corrected by an earth sensor 1 for detecting an angle around X axis, and sun sensor 4, 6 for detecting angle around X axis and Z axis. In this case, since the X axis is separated from the direction of the sun, the sun direction bias amount decided by the orbit position is added to the output of the sun sensor 4, 6 for detecting the angle around the Y axis and Z axis. Since an attitude angle around the X axis is decided by an orbit position D, the point D is decided from the polarity inversion time of the output of an earth sensor 2 for detecting angle around the Y axis.

Abstract: PROBLEM TO BE SOLVED: To provide a highly efficient brushless motor which is less in vibration and noise by logically processing a position detecting signal by means of a conduction switching circuit and switching the conduction of motor driving coils by means of a switching element group by using a conduction switching signal. SOLUTION: A position detecting means 30a outputs the signal corresponding to the position of a permanent-magnet rotor 20. A position detecting signal outputted from the detecting means 30a is inputted to a conduction switching circuit 40a. The circuit 40a logically processes the position detecting signal and outputs a conduction switching signal. A switching element group 50 drives a brushless motor by switching the conduction of motor driving coils in accordance with the conduction switching signal. Therefore, a highly efficient brushless motor which is less in vibration and noise can be obtained by making the conducting electrical angle of the motor driving coils larger than the angle obtained by dividing 360 deg. by the number of phases of the motor driving coils and efficiently conducting the coils.
