Title: Fuel injection timing controller for diesel engine
Inventor: OGAWA TOSHIHISA
IPC: F02D41/40
Filed: 1983-01-31
Abstract: PURPOSE:To reduce the operation noise of an actuator for controlling injection timing by suspending fuel injection timing control when an engine starts. CONSTITUTION:A power source 31 is connected to the fuel injection timing means of a Diesel engine and a timer means through a key switch 32, and when the key switch 32 is turned ON, the timer means begins to measure a prescribed time. During this time, the timer means stops the operation of the fuel injection timing control means. In other words, the fuel timing control means stops operation for a prescribed time after the key switch 32 is turned-ON. Thus, the operation noise can be reduced.

Title: Amplifying circuit of bar code reader
Inventor: YAMAZAKI NOBUHISA
IPC: G06K7/10
Filed: 1984-01-27
Abstract: PURPOSE:To remove influence of density and secular change of a bar code and to obtain a sufficient margin for noise by differentiating a mark sensor output once, then restoring a pulse wave form by utilizing positive/negative peaks of the differential signal. CONSTITUTION:A signal (b) outputted from a mark sensor is differentiated in a differentiation circuit 1, and a signal (c) is generated. The signal (c) is impressed to a positive peak holding circuit 2, a negative peak holding circuit 3 and differential amplifiers 4 and 5 in parallel. The circuit 2 holds successively a positive peak level of the signal (c), and the circuit 3 holds successively a negative peak level of the signal (c). The differential amplifiers 4 and 5 compare the signal (c) with output levels of the circuits 2 and 3, and if fluctuation of the signal (c) is larger that either output levels of the circuits 2 and 3, the amplifiers 4 and 5 output a signal (e) or a signal (f). By utilizing these signals obtained in such a way, a latch circuit 6 is set or reset alternately; therefore a target pulse signal (g) with a shaped bar code mark can be generated.
