Title: Extrusion molding apparatus
Inventor: NAKAMURA TAKASHI
IPC: B29C48/30
Filed: 1994-12-15
Abstract: PURPOSE: To eliminate the stagnation of a raw material in order to stably extrude the raw material for a long time by constituting a raw material flow prescribing die of an almost pentagonal pillar-shaped member wherein a triangular prism part of which the bottom angle is a specific value and a square pillar part of which the long side is common to the bottom side of the triangular prism part are integrally constituted and setting the apex of the triangular prism part of the raw material flow prescribing die to a raw material outlet direction. CONSTITUTION: The shape of the raw material flow prescribing die 13 provided in a mold receiving a raw material from the introducing ports 5-1, 5-2 provided to both side surfaces of the mold is set to an almost pentagonal pillar shape wherein a triangular prism part 13 and a square pillar part 14 are integrated. The apex CC' of the triangular prism part 13 is turned toward a raw material outlet and the angles CAB, CBA of the bottom angle parts of the raw material flow prescribing die 13 are set to 30-45 deg. and the raw material introducing ports 5-1, 5-2 are arranged to the sides AA', BB' thereof. By setting the angles of the bottom angle parts of the raw material flow prescribing die 13 to 30-45 deg., the stagnation of the raw material is eliminated and extrusion pressure loss is lowered. The extrusion pressure loss is lowered because the frictional resistance between a stagnated solidified surface and a fresh raw material surface is larger than that between the raw material flow prescribing die 13 and the fresh raw material.

Title: Method and system for automatically sorting breakdown voltage waveform of semiconductor device
Inventor: TAKEDA TOYOHIKO
IPC: G01R31/26
Filed: 1998-11-04
Abstract: PROBLEM TO BE SOLVED: To shorten the time required for sorting the withstanding waveform of all field effect transistors on a semiconductor substrate by measuring the drain leak current of the field effect transistor with a plurality of set voltage and then sorting the withstanding waveform automatically, based on the measurements. SOLUTION: First, the drain leakage current of a field effect transistor is measured by means of a tester 1 with a plurality of set voltages, and measurements are stored in a memory 2 along with arrangement indexes and the set voltages. The data stored in the memory 2 are outputted as the source/ drain voltage vs drain leak current and are displayed on the screen of a terminal computer 4. Since the withstanding waveform pattern of the FET can be sorted automatically, the time required for sorting the withstanding waveform of FETs on a semiconductor substrate can be reduced significantly. Furthermore, the manufacturing process of semiconductor device can be reduced because the breakdown voltage waveform pattern of the FET can be sorted only through the decision from the use of the tester.
