Title: Method for casting mold
Inventor: YAMAGUCHI FUMIO
IPC: B22D27/18
Filed: 1997-06-17
Abstract: PROBLEM TO BE SOLVED: To provide a method which cools an entire mold evenly and improves its quality by pouring molten steel into the mold coated partly with a glass- based coating material, and covering a cast with another coating material, and then cooling the cast slowly after the mold is released. SOLUTION: A glass-based coating material is composed to coat the surface of the mold. The coating is applied to rib-forming parts and corner parts of the mold, and molten steel is poured into the mold. The heat of the molten steel turns the coating material into glass layers 13 to cover the mold partly. Parts coated with glass layers 13 are cooled slowly after the cast is removed from the mold. As the glass layers serve as thermal insulating materials, the rates of cooling the surface of the mold can be varied partly. Also, an alloy- based coating material is put on the surface of the mold, and the alloy-elements- based coating material is melted by the heat of the molten steel poured into the mold and penetrates into the surface of the cast so that the quality of the surface of the cast is improved. The alloy-elements-based coating material may be mixed with glass-based coating materials.

IPC: B44C1/24
Filed: 1992-05-27
Abstract: PURPOSE:To provide a method for forming a pattern on a metal or a resin without requiring mechanical processing such as by a carving machine, at a low cost and free from pattern restrictions. CONSTITUTION:A harder metal or ceramics than a base 1 of metal or resin is formed in a pattern (hard pattern 2) on said base 1. Then this whole material is pressed to embed the metal or ceramic pattern 2 in the base 1 or a recessed pattern is formed by removing the hard pattern embedded in the base 1. This method is such simple that the hard pattern 2 which is harder than the base 1 and formed on the base 1 is pressed, or the hard pattern 2 is removed after pressing the hard pattern 2. Therefore, machining such as by a carving machine is no longer required, and a pattern is formed on a metal or a resin at a low cost and free from pattern restrictions.

Title: Ignition device
Inventor: ARAI ATSUO
IPC: F23Q3/00
Filed: 1979-12-11
Abstract: PURPOSE:To reduce a consumption power by a method wherein in an oscillating  type ignition system using thyristor, power is boosted at ignition and after ignition, a minimum sparking power to enable to continue a combustion is retained. CONSTITUTION:When an input power is turned ON, in a positive half cycle of an oscillation period, a capacitor C2 is charged through a diode D1, an inductance L1, the primary winding of an ignition transistor T, a resistor R1 and a resistor R2 and a diode D4, both of which are in parallel to the resistor R1. At the same time, a capacitor C3 is also charged by means of the diode D1 and a resistor R3. When said charging voltage exceeds a base voltage of a transistor Tr, the transistor Tr is  turned ON, and the charging current to the capacitor C2 is bypassed through a  resistor R2 and further, an oscillating frequency becomes low, thereby, making an  output power small.

Title: Valve gear mechanism apparatus
Inventor: YAMAZAKI SHOJIRO
IPC: F01L1/053
Filed: 1989-06-26
Abstract: PURPOSE:To enlarge a valve opening area and drive opening/closing at high speed by a method wherein a valve on a farther side from a cam shaft offset and pivoted is opened and closed by a second rocker arm rocked via an intermediate rocker arm. CONSTITUTION:In a valve gear mechanism apparatus 14, a cam shaft 15 is offset toward an inlet valve 6 so that it does not interfere with a spark plug 13 to be pivoted on an upper section of a cylinder head 1. An air suction rocker arm 22 is rocked by the cam shaft 15 to open/close the inlet valve 6. A second exhaust rocker arm 35 opens/closes an exhaust valve 7 via a first exhaust rocker arm 28 by the cam shaft 15. Thus since the spark plug 13 is attached perpendicularly to the cylinder bead 1, valve opening areas of the air inlet- exhaust valves 6, 7 can be increased. In addition since inertial mass of the valve gear mechanism apparatus 14 can be reduced, the air inlet-exhaust valves 6, 7 can be driven to open/close at high speed.
