Title: Logical simulation method and device
Inventor: KATO KOJI
IPC: G01R31/28
Filed: 1999-04-19
Abstract: PROBLEM TO BE SOLVED: To provide logical simulation method and device capable of obtaining accurate power consumption and delay time reflecting the influence of self heat generation. SOLUTION: For respective gates which are the constituting elements of a logic circuit to be simulated, gate power consumption (PG) and gate delay time (Tg) are calculated based on a function defined with the self heat generation TH of the gate as a parameter. The entire power consumption Ph and entire delay time Th of the entire circuit are calculated based on the calculated values PG and Tg and a heat generation parameter THp obtained by averaging the self heat generation TH obtained from the gate power consumption PG for respective blocks composed of one or plural gates.  Until the deviations of the respective calculated values Ph, Th and THp in the processing of a previous time and the processing of this time all become within an allowable range, the newly calculated heat generation parameter THp is fed back as the self heat generation TH and the above-mentioned processing is repeatedly executed.

Title: Address extension system
Inventor: TAKECHI HIROAKI
IPC: G06F13/10
Filed: 1977-09-14
Abstract: PURPOSE: To enable to connect exctension memory only with a simple control circuit by locating the extension address register to the extended memory side and by  accessing for this register with the address in the basic address space.  
     CONSTITUTION: CPU accesses first the extended address register EAR in the extended memory controller EMC, and the upper rank n-bit of the head address of the area of extension memory EM for the objective is written in with the store instruction twice. Further, accessing is made by selecting either of the addresses among the specific bytes in the fundamental memory area. When the controller EMC monitors the address pattern and detects that it is the specific address, the lower rank m bits of the address of the common BUS are fetched and they are synthesized with the data of register EAR and delivered to the memory EM in m+n bits. Thus, the accessing to the extended memory EM is executed with the same speed similarly as the case with the fundamental memory via the control circuit EMC.

Title: Print recording head
Inventor: AKUTSU HIDEKAZU
IPC: B41J2/32
Filed: 1988-05-10
Abstract: PURPOSE:To improve the reliability of contact by arranging a plurality of recording electrodes in parallel on a thin resin substrate, forming a protrusion of an electroconductive material near the tip of each said electrode and providing a notched groove between electrodes at least on the tips of these electrodes. CONSTITUTION:Due to recording electrodes 2 provided on an elastic resin substrate 1, a print recording head deforms along the uneven surface or undulation of the surface of a print recording medium, if such exists. Consequently, a protrusion 4 provided at the tip or near the tip of the recording electrodes 2 can always be kept in a stable contact state. In addition, because of a notched groove 5 provided between the recording electrodes on the substrate, the recording electrodes are placed in a pressed contact state individually or in a plurality of groups independently. This state does not allow the whole print recording head to float, if the recording electrodes 2 section is contaminated with foreign matter such as dust. Furthermore, if the recording head becomes afloat, it can hardly affect the other recording electrodes.
