Title: Dynamic memory refresh circuit
Inventor: FUKUDA SHIGEAKI
IPC: G11C11/407
Filed: 1993-05-13
Abstract: PURPOSE:To retrain the troughput from lowering by monitoring the access request to a dynamic memory using a refresh timer and requesting the refresh immediately after request of access thereby resolving the conflict of request. CONSTITUTION:When a CPU accesses a DRAM, an address decoder 1 decodes an address from the CPU and delivers an access request (a). A refresh timer 2 monitors the access request (a) and delivers a refresh request (b) to the DRAM immediately upon finish of the access request (a). A refresh arbiter 3 arbitrates the access request (a) and the refresh request (b) and delivers an arbiter output. Consequently, the timer 2 delivers the refresh request (b) only when the access request (a) is not delivered from the CPU to the DRAM. This constitution reduces conflict of access request and refresh request thus restraining the throughput from lowering.

Title: Injection timing control circuit of fuel injection device for diesel engine
Inventor: YAMADA GENICHI
IPC: F02D41/40
Filed: 1980-08-13
Abstract: PURPOSE: To precisely control an injection timing, by quickly responding to even abrupt change of a crank angle speed of engine.  
     CONSTITUTION: An arithmetic circuit 40 generates a interporation pulse depending upon an angle pulse outputted in synchronism with rotation of an engine crank shaft. In this time, the interporation pulse is controlled so that it may have a prescribed harmonic frequency with respect to the frequency determined by the period from the immediately preceding angle pulse to the follwoing angle pulse whenever the latter angle pulse enters, to have the angle pulse and interporation pulse measured by counters 60, 62. An injection timing to which is an action lag of a fuel injection valve taken into account depending upon running condition of engine is digital operated by the arithmetic circuit 40, and then valves which have been measured by the counters 60, 62 is compared with said arithmetic value by digital comparators 70, 72 to determine an injection timing.
