Title: Molding method of wax model having ceramic core
Inventor: ISHIHARA MAKOTO
IPC: F01D5/18
Filed: 1999-03-02
Abstract: PROBLEM TO BE SOLVED: To obtain a model which does not generate core cracks by installing a solid wax between a ceramic core surface and a mold inner face in advance, before the molten wax is injected inside the mold. SOLUTION: A molten wax is injected between the core outer surface of a wax model ceramic formed from a product drawing and a mold inner surface. Then, the face of the ceramic core is checked to see which face of the core is pressured by interrupting injection or the like. The solid wax with the same thickness as a space between the ceramic core surface opposed to the pressure applied face and the mold inner surface is adhered on the ceramic core surface opposed to the pressure applied face. The solid wax is made to be a sheet with an adhesive. During injection of the molten wax, if the pressure is applied to the ceramic core, the mold inner surface holds the ceramic core via the solid wax so as to prevent fracture of the core. It is suitable for the wax model having an expensive ceramic core such as a moving blade or the like for a gas turbine by a lost wax precise casting method.

IPC: B30B15/00
Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To automate cleaning work and to improve the efficiency of press process by an apparatus wherein when press work by using a press mold in press molding process is performed for a specified number of operations or a specified time from the previous cleaning, a moving part is controlled so as to make a small-sized brush approach the press mold. SOLUTION: A press-molded article is molded by means of a press of a top force 5 and a bottom force 7 set in a press main body and is kicked out by means of a press feeder. Cleaning of the top and bottom forces 5 and 7 is constituted by actuating successively such operations as movement of a brush 9, discharging of a press failed work and stopping of the bottom force 7 at the top dead spot. It becomes possible to perform an unattended operation of the press mold process as the cleaning work for the press mold for ceramic powder can be completely automated like this. In addition, as timing, frequency and the number of times of cleaning of the mold can be easily changed by setting of a counter, it becomes easy to cope with press processing of variety of products.

IPC: F02P5/15
Filed: 1993-03-15
Abstract: PURPOSE:To keep the thermal efficiency and output of a spark ignition internal combustion engine maximum by calculating the ratio between the change quantity of the ignition timing and the change quantity of a load in the internal combustion engine, and maintaining the ignition timing as it is when the calculated value falls in the prescribed range. CONSTITUTION:The load of an internal combustion engine is detected by a detecting means 6, and the ignition timing is detected by a detecting means 10. The ignition timing of the internal combustion engine is changed by a changing means 13. The ratio between the change quantity of the ignition timing and the change quantity of the load, i.e., the differential value dT/dtheta, is calculated by a means 12 based on the detected load and ignition timing. When the absolute value of the calculated differential value falls in the range of the prescribed small value, the ignition timing is maintained as it is. When it falls outside the range, the means 13 is controlled by a processing means 1 to change the ignition timing so that it falls in the range. The thermal efficiency and output of the spark ignition internal combustion engine are kept maximum.

Abstract: PURPOSE: A curative composition which provides, in combination with a suitable base material, a room-temperature curing elastomer useful as an elastic paving material or a water-proofing material, including a methylene-bridged polychloroaniline and a polyoxyalkylene polyol.  
     CONSTITUTION: A curative composition for a room-temperature curing polyurethane elastomer, including (A) a methylene-bridged polychloroaniline represented by the formula, wherein n is 0 or a positive integer, and (B) a polyoxyalkylene polyol. As the material for producing (A), chloro-substituted aniline is used entirely instead of using aniline and, therefore, the compound (A) shows a lower reactivity toward isocyanate groups. Therefore, the viscosity of the reaction mixture increases relatively slowly during the production of polyurethane elastomers, with consequent long usable life and excellent operability. The most general of (B) is a polyoxypropylene glycol having an average MW of 200W8,000, and this compound acts also as a solvent for maintaining the curative composition in liquid at room temperature.
