Abstract: PURPOSE:To make it possible to form a large memory capacity in a small area by a method wherein two capacitors, having a silicon substrate and the second polysilicon electrode as opposed electrodes, are formed on the upper and the lower parts of the first polysilicon electrode, they are used in parallel, and the first polysilicon electrode is connected self-matchingly without using a contact hole. CONSTITUTION:The first capacitor is formed on the lower layer of the first polysilicon electrodes 22a and 22b between said lower layer and a silicon substrate 1. Also, the second capacitor is formed on the upper layer of the first polysilicon electrodes 22a and 22b between said upper layer and the second polysilicon electrode 5. Using the first polysilicon electrodes 22a and 22b as a memory terminal, said two capacitors are self-matchingly connected to a read-out and write-in transistor AT without using a hole 8, the contact hole is removed and the area of a memory cell is made small considerably. Accordingly, the two capacitors act in parallel, and as the memory terminals 22a and 22b are separated from the substrate 1, a structure which is strong against the leak and the soft error generating between the adjoining memory cells can be obtained.

Title: Air intake system for four-cycle type multiple cylinder internal combustion engine
Inventor: NISHINA AKIRA
IPC: F02M35/104
Filed: 1990-02-27
Abstract: PURPOSE:To increase the extent of power for an internal combustion engine by constituting a butterfly valve installed in an intake pipe so as to open an opening on one side and to close an opening on the other by dint of intake pressure in one opening in these two openings. CONSTITUTION:When a No. 1 or No. 4 cylinder is in an intake stroke, a butterfly valve 10 is opened of its opening 3-1A dint of inlet negative pressure, and thereby fresh air inlet charging takes place in the No. 1 or No. 4 cylinder by way of a passage being shown with a white arrow. On the other hand, residual exhaust gas flowing back in an overlap period of the next sequential combustion cylinder operates on an opening 3-1B, therefore it functions as merely exhaust pressure, pressing the valve 10 counterclockwise. In consequence, each surface pressure of a seat face 13A and a backing 12 is made to go up inevitably, thus this fact conduces to improvement in sealability for preventing the residual exhaust gas in the opening 3-1B from penetrating into the opening 3-1A. Therefore fresh air inlet charging efficiency is enhanced and, what is more, combustion efficiency is improved.
