Title: Manufacture of semi finished steel or nickelous system alloy
Inventor: LEE HYU SHO
IPC: C23C4/12
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To improve abrasion resistance property or mechanical properties by making it a semi finished item, wherein a nitrogen or a nitrogen contained gas is sprayed, after a given value of titanium is added to a steel which does not contain a titanium or a nickel system liquid alloy. SOLUTION: A billet is made by a spray forming of an alloy, wherein a titanium added volume is set to be 0.01-2.5 wt.%, preferably 0.1-1.0 wt.%, in a nitrogen gas atmosphere. Thus, a titanium nitride is formed, being dispersively precipitated as a fine precipitate, and a material character of the alloy is improved by restraining a growth of grain size, coarse graining at the time the billet is finally solidified and cooled. Specifically, after adding 1% Ti to a given liquid metal composition, for example, a molten alloy composed of C: 0.1%, Cr: 12%, Mo: 1.75%, Ni: 2.5%, V: 0.3%, the nitrogen gas is used as a double spraying device. A dropping which being partially solidified with the liquid is sprayed to a moving collector disc so as to make a billet in a range of diameter being 200-500 mm, and of 2 m length.

Title: Valve timing control device for internal combustion engine
Inventor: KATO YUICHI
IPC: F02D13/02
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To provide a valve timing control device for an internal combustion engine, which suppresses to the minimum the lowering of the performance of the engine and prevents the unstableness of a valve timing during a period from engine start to oil temperature rise. SOLUTION: A vane type variable valve timing mechanism 10 is arranged in an internal combustion engine, and an intermediate position lock pin is arranged on the vane body 110 of the mechanism 10. An intermediate position lock hole matched with the position of the intermediate position lock pin when the vane body 110 is positioned in the middle between the most phase lag position and the most phase advance position from a housing 100, is arranged in the housing 100 of the mechanism 10. After the engine is started, viscosity of hydraulic fluid is high during oil temperature is low, therefore valve timing feedback control becomes unstable. During oil temperature is low, a control circuit 30 makes the intermediate position lock pin engage with the intermediate position lock hole by hydraulic pressure so as to fix the vane body 110 in the intermediate position.  Hereby, valve timing is fixed and unstableness of the valve timing may not occur.

Title: Suction/exhaust operation selector for internal- combustion engine
Inventor: OOKI HISATOMO
IPC: F01L1/04
Filed: 1984-02-08
Abstract: PURPOSE:To secure a valve lift value corresponding to a kinetic condition, by making a cam shaft driving a rocker arm shift to some extent accroding to the kinetic condition of an engine. CONSTITUTION:A cam shaft 3 driving a rocker arm 4 is supported by a piston 6. Control hydraulic pressure is added to a cylinder 8 being inserted into the piston 6, and when an engine speed is slow, an on-off valve 9 closes but a relief valve 12 opens the other way, while the piston 6 is situated in a lower end position, and a lift value in a suction-exhaust valve 2 becomes small. When the engine speed is high, the relief valve closes but the on-off valve 9 opens and, after the piston goes up, the on-off valve 9 closes by operation of a limit switch 16 whereby the piston 6 is held at an upper end position, thus the lift value of the suction-exhaust valve grows large. With this constitution, charging efficiency becomes improved and high engine performance is thus securable.
