Title: Mold model
Inventor: KANAMORI MITSUO
IPC: B22C7/00
Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To improve the durability of a model part by preventing the foreign materials such as sand and the like from letting in the junction of the die and model part where an outer mold, which corresponds to the original shape of the die, and the mating surface of the die and the model part, formed with a soft and compatible material, are closely fixed. SOLUTION: This model comprises a model part 3 consisting of silicon rubber. The upper part of the epoxy resin acts as a mating face 4, and its top surface acts as a mating face 4a against the mold. A postenior of the model part 3 and a bottom part of the epoxy resin 4 serve as a backup 5. However, as the contacting face of the epoxy resin and the silicon rubber is not coated with the mold lubricant, the model part 3 and the backup 5 are fixed to each other. The model part 3 and the mating surface part 4 are closely fixed to each other, since the mold lubricant is not coated on that part even though the lower end part of the silicone rubber is submerged in the epoxy resin.

Abstract: PROBLEM TO BE SOLVED: To improve durability of an auxiliary brake and reduce emission of soot from an engine by optimizing a timing when the auxiliary brake actuates in a transmission control system for shortening shift time by actuating the auxiliary brake. SOLUTION: An engine control unit 82 sets a pseudo accelerator opening degree which gradually decreases as time passes in accordance with a shift-up command from an electronic control unit 80. The engine control unit 82 then controls an injection amount of fuel based on the pseudo accelerator opening degree. When the pseudo accelerator opening degree is smaller than a predetermined valve or the injection amount of fuel is zero, the electronic control unit 80 actuates exhaust brakes 104, 106 judging that the engine is in a no-load running state.
