Title: Method for molding foamed resin molded product
Inventor: ONISHI KAZUSHIGE
IPC: B29C45/16
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To prevent the forming of a beveled face at the corner parts of a molded product from occurring. SOLUTION: A movable core 21 which expands and shrinks a cavity 1a to be formed by the fixed half 1 of a mold and the movable half 2 thereof is stored in the movable half 2. Further, a molten resin containing a foaming agent is injected into the cavity 1a whose volume is diminished by the movable core 21 , from the fixed half 1 side to first form solid layers 3a, 3b and then the volume of the cavity 1a is expanded by moving the core 21 backward to a specified position, to form a space 1g. Next, the molten resin containing the foaming agent is again injected into the space 1g from the fixed half 1 side, and is cooled by the mold face of the fixed half 1 of the mold to form a skin layer 3c which is continuously formed with the solid layer 3b. Thus a core layer 3d formed of a foam layer is formed in the inner part encircled by the skin layer 3c and the solid layers 3a, 3b.

Abstract: PURPOSE:To decrease the dispersion in resistance of Hall sensor elements and unbalanced voltages by overlapping a metal layer whose main component is Au, a Ta layer, and an Au layer on a GaAs substrate, and specifying the thicknesses of said layers. CONSTITUTION:SiO2 4 is deposited on an epitaxial layer 3.1 having the carrier concentration of about 5X10<15>cm<-3> on a GaAs insulating substrate 3 of (100) face. A hole is perforated in the SiO2 film 4, and AuGe 5, Ta 6, and Au 7 are consecutively deposited. In this case, the thicknesses of said layers are controlled so that the thickness of AuGe is 0.1-0.3mum, the thickness of Ta is 0.1-0.3mum, and the thickness of Au is 1-2mum. Then, each layer except the electrode 2 is etched out by the photoetching method. Furthermore, a Hall bar 1 and the electrode 2 are covered by a resist, the SiO2 film 4 is etched out, and the epitaxial layer 3.1 and the substrate 3 are etched. Finally, the heat treatment is performed in H2, and uniform ohmic contact is formed between AuGe and GaAs of the electrode 2. In this constitution of the Hall sensor, the dispersion in the unbalanced voltages and the resistance of the elements are very small, and the yield rate is excellent.

IPC: A23N12/10
Filed: 1995-04-27
Abstract: PURPOSE: To obtain a roasting apparatus for a granular material having simple structure and capable of surely transmitting the driving torque from a power. source to a stirring blade. CONSTITUTION: A rotary shaft 3 having a stirring blade 4 at the top is connected to an output shaft 5 of a power source 6 via a shaft coupling 10 composed of a coil spring 7, a joint member 8 and a pin 9. Since the shaft-holding hole of the joint member 8 is engaged with the engaging ridge 5a of the output shaft 5 by the ridge-groove coupling, there is no slippery between the output shaft 5 and the joint member 8 even if a relatively large reaction force is applied to the joint member 8 by the coil spring 7. Accordingly, the slipping of the output shaft 5 can be prevented even if the tip of the joint member 8 is engaged with the lower piece 7c of the coil spring 7 by the positional deviation between axes of the rotary shaft 3 and the output shaft 5.
