Title: Suction-exhaust valve driving device for internal-combustion engine
Inventor: HARA SEINOSUKE
IPC: F01L13/00
Filed: 1982-10-15
Abstract: PURPOSE:To keep a valve clearance adequate at all times and control a separate distance between an arm and a lever according to a state of driving as well as to reduce a control loss to the smallest possible extent, by setting a bracket, which presses a rocker arm down to a stem end, to the back of the lever. CONSTITUTION:The lift volume and on-off timing of a valve 12 performs variable control by altering a separate distance between a lever 5 and a rocker arm 13 with control hydraulic in a hydraulic pivot 19. When the arm 13 exists on the base cycle of a cam 11, the reaction force of a valve spring 12a will act on nothing, therefore large control hydraulic pressure is no longer required. In addition, a hydraulic piston 32 is energizing the lever 15 to move in a direction toward the valve 12, and because of inclines 15c and 18a being slidingly contacted with each other, the lever 15 presses the end of the arm 13 down to a stem end 12b so that it can keep a valve clearance constant all the time.

Title: Packaging container
Inventor: HAYAKAWA YOSHIHARU
IPC: B65D81/07
Filed: 1999-06-28
Abstract: PROBLEM TO BE SOLVED: To obtain a packaging container which absorbs shock to protect contents without using a cushion by providing a magnet on the internal surface of a container wall and placing another magnet on the surface of the contents so that a pole of the same polarization is opposite to that of the magnet on the container wall so that repulsion between the magnet on the container wall and the magnet on the contents causes buffer action. SOLUTION: Respective plate-like magnets 4 stuck to an internal surface of a regular hexahedron container 2 wall and an internal surface of a lid 3 are placed on the entire internal surface of the container 2 so that the same poles are oriented inwardly. In addition, respective plate-like magnets 5 stuck on the surface of a regular hexahedron contents 1 are placed on the entire surface of the contents 1 so that the same poles as those of the magnets 4 on the container 2 wall are oriented outwardly. Thus, when the contents 1 are received in the container 2, and the lid 3 is closed, the magnets 4 and the magnets 5 on the respective surfaces repulse to each other, and the repulsive force causes the contents 1 to be supported in a floating state inside the container 2.  Since the packaging container can thus keep the contents 1 apart from the container 2 walls, and also always keeps the state of electrical insulation, so the container is suitable to transportation of electronic components or the like which are sensitive to static electricity.
