Title: Opening and closing device of cylinder valve
Inventor: KAKEGAWA TOSHIAKI
IPC: F01L9/14
Filed: 1982-02-27
Abstract: PURPOSE:To stop operation of intake and exhaust valves, by controlling fluid in an oil cylinder in an engine in which fuel injection partly to a cylinder is stopped to idle the combustion. CONSTITUTION:When a fuel injection cylinder is cut by idling a cylinder provided with a cylinder valve 3, a solenoid valve 30 is opened. Even if a cylinder 15 is lifted by a cam 20, oil in the cylinder 15 flows in through a spill port 24, spill gallery 26 and the solenoid valve 30 to an exhaust pipe 31. Accordingly, a piston 21 of this cylinder 15 is not moved in a stationary state to an original position, and the valve 3 is held to a closed condition by a spring 7. In this way, when the fuel injection cylinder is cut, an idle cylinder is less loaded and consumption of fuel can be decreased.

IPC: C23C28/00
Filed: 1990-02-13
Abstract: PURPOSE:To increase the adhesive strength of a film and to form a stable and uniform black-colored layer by applying etching to the surface of a copper- containing gold alloy and forming a sialon film in an oxygen-containing atmosphere. CONSTITUTION:Etching is applied to the surface of a copper-containing gold alloy, by which microscopic ruggedness is formed in the surface. A sialon film is formed on the surface of the above gold alloy in an oxygen containing atmosphere. Simultaneously with the formation of this sialon film, a copper oxide is formed at the boundary between the sialon film and the gold alloy by the reaction between the copper component in the gold alloy and oxygen. The resulting copper oxide has a black color. This copper oxide exists stably on the surface of the gold alloy because it is coated with the sialon film, and further, this copper oxide provides luster to the gold alloy. By this method, the adhesive strength between the gold alloy and the sialon film can be improved, and the formation efficiency of the copper oxide can be increased.

Title: Forced refresh device
Inventor: ISOBE YOKO
IPC: G11C11/406
Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To enable exact performance measurement by issuing a refresh instruction at arbitrary timing and suppressing the memory access instruction in a CPU. SOLUTION: When the refresh instruction 4 is issued, a request conversion circuit 5 delivers the same to a refresh control circuit 7 and delivers the same to a refresh state instructing circuit 6. This refresh state instructing circuit 6 sends a DRAM state instruction signal 15 to the CPU and suppresses the memory access instruction. On the other hand, the refresh control circuit 7 refreshes a DRAM 3 by the force refresh signal 11 from the request conversion circuit 5 or the refresh request 13 from a time measurement circuit 8. The DRAM 3 sends signals to the refresh control circuit 7 and the refresh state instructing circuit 6 to release the memory access instruction suppression when the refresh ends. As a result, the refresh instruction is issued at the arbitrary timing and the exact performance measurement is made possible.
