Title: Nonvolatile dram
Inventor: NAGAI YOSHIKAZU
IPC: G11C14/00
Filed: 1989-06-08
Abstract: PURPOSE:To make a circuit into a highly integrated circuit by using an NMOS transistor in a dynamic memory cell as a nonvolatile storage element instead of a static memory cell. CONSTITUTION:The NMOS transistor Q1 and a selective MOSFET Q1 are connected in series to the electrode on one side of the accumulative capacitance element Cs of a dynamic memory cell part. When data is rewritten, since a DRAM mode is set and a transfer mode can be set when information held with a memory cell is returned to the dynamic memory cell part of the memory cell prior to the DRAM mode, the data in the memory cell can be preserved when a power source is disconnected as keeping the same access speed as that of an ordinary DRAM between the outside. In such a way, by using the dynamic memory cell and using the NMOS transistor as the nonvolatile storage element, structure can be simplified.

Inventor: NISHIKAWA KATSUMI
IPC: B60H3/06
Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To provide an installation structure that can suppress vibration transmitted to an air cleaner via a bracket. SOLUTION: In a bracket for installing an air cleaner to a seat back 1, an anchor portion 6A is held at top and bottom sides thereof between one end portion 2a of an upper metal fitting 2 and a lower metal fitting 3. Further, the one end portion 2a of the upper metal fitting 2 and a receiver 3c of the lower metal fitting 3 are fastened by a screw 7. Accordingly, the top face of the anchor portion 6A and the one end portion 2a of the upper metal fitting 2, as well as the bottom face of the anchor portion 6A and the bottom potion 3a of the lower metal fitting 3, come into close contact. Consequently, a gap between the anchor portion 6A and the bracket which causes looseness is eliminated and the bracket can be surely fixed to the anchor portion 6A, thus suppressing vibration transmitted to the air cleaner via the bracket.  Therefore, even an air cleaner incorporating electrically controlled parts that are vulnerable to vibration can be installed to the seat back 1.
