Title: Die for extruder
Inventor: ISHIDA MAMORU
IPC: B29C48/30
Filed: 1997-07-15
Abstract: PROBLEM TO BE SOLVED: To suppress the development of specks due to gum and wrinkles due to eddy currents even through the high speed efflux of a thermoplastic resin by a method wherein a trumpet-like curved wall having a specified radius of curvature is formed at the outlet part of a flow passage in the die for an extruder. SOLUTION: In the die 1 for an extruder, a trumpet-like first curved wall 5 having the radius of curvature R1 of 0.1-10 mm is formed between the front wall 3 of the outlet part 2 of a flow passage F and a hole part 4 with an inner diameter D. Further, preferably a convergent second curved wall 8 having the radius of curvature R2 of 0.1 mm or more is formed between the rear wall 7 of the inlet part 6 of the flow passage F and the hole part 4. In this die 1, melted thermoplastic resin flows in the inlet part 6 through the second curved wall 8, the hole part 4 and the first curved wall 5 from the outlet part 2. Due to the formation of this trumpet-like first curved wall 5, the development of gum at the outlet part 2 is remarkably suppressed.  On the other hand, due to the formation of the convergent second curved wall 8, the development of eddy currents at the boundary part between the hole part 4 and the curved wall can be prevented.

Title: Method and apparatus for electric discharge sintering
Inventor: INOUE KIYOSHI
IPC: B22F3/14
Filed: 1989-07-25
Abstract: PURPOSE:To obtain a good quality sintered body having lense and uniform guality and high dimensional accuracy by compressing material under high pressure before conducting electric current and successively, compressing and sintering while applying the pulse current. CONSTITUTION:The prescribed quantity of material is charged into a die 15 in a vacuum vessel 4. The vacuum vessel 4 is tightly closed to make vacuum condition in a sintering furnace 12. An upper punch 10 and lower punch 11 are worked and the material is compressed at 5 - 20 T/cm<2> press are to make a high density green compact. After that, the pulse current is supplied to the upper and lower punches 10, 11 and the material is compressed and sintered while controlling the material temp. by controlling peak current and pulse width. As shrinkage ratio is little by conducting the current for sintering, this is suitable to the die sintering. Further, as the sintering temp. is low, the conductive current is a little and therefore, the power source circuit may be sufficient with comparatively small capacity.

Title: Fuel feed amount control device for internal combustion engine
Inventor: KASUYA KAZUSATO
IPC: F02D41/04
Filed: 1988-07-29
Abstract: PURPOSE:To improve running performance by a method wherein when it is decided that a throttle opening detecting value is abnormal, an intake air pressure detecting value detected by an intake air pressure sensor is compared with a high load area set value lower than a high load set value during normal running to discriminate whether the high load increase of a fuel feed amount is needed. CONSTITUTION:When a throttle opening detecting value TA is normal, an intake pressure detecting value PIM having high detecting precision on a flatland is utilized and a throttle opening detecting value on a highland is utilized to properly detect the high load area of an internal combustion engine. When the throttle opening detecting value TA is abnormal, the intake air pressure detecting value PIM by an intake pressure sensor 20 is compared with a high load area set value P2 lower than a high load area set value P1, and this comparison causes detection of a high load area. Thereby, a high load area on a highland can be properly detected without increasing a high load area and a detected region on a flatland so much. This constitution causes proper control of a fuel feed amount and improves running performance as fuel consumption and exhaust gas emission are maintained in an excellent state.
