Title: Organic metal vapor phase crystal growth device
Inventor: OTA YOICHIRO
IPC: H01L21/205
Filed: 1990-03-23
Abstract: PURPOSE:To improve safety without use of group V hydride and without necessity of supply of excessive raw gas by using a group V simple substance as a group V element raw material and by using vapor generated through heating by introducing to a reaction tube. CONSTITUTION:A group III element raw material is introduced to a reaction tube 3 from an organic metal gas cylinder 2 using hydrogen gas as carrier gas. Meanwhile, a group V element raw material is provided as a simple substance 10 inside a group V element supply tower 8 and heated by a heater B9; thereby, generated vapor is introduced to the reaction tube 3 by carrier gas 11. Each raw material supplied in this way is heated, decomposed and reacted by heat of a wafer 4 put on a susceptor 5 which is heated by a heater A7 of an RF coil and deposits on the wafer 4 as a crystal. Thereby, the group V element raw material reacts with group III element raw material effectively, making supply of excessive raw material unnecessary and improving safety.

Title: Tundish for continuous casting
Inventor: YAMADA KATSUHIKO
IPC: B22D43/00
Filed: 1979-06-14
Abstract: PURPOSE:To pass molten steel between shelves and separate away nonmetallic inclusion particles by providing multiple stages of shelves of refractory materials between the receiving steel bath region which receives the molten steel of a tundish and the tapping bath region which pours molten steel into a mold. CONSTITUTION:Multiple stages of shelves 5 of refractory materials are provided at the intermediate of the receiving steel bath region 3 which receives molten steel from the ladle of a tundish and the tapping bath region 4 which pours molten steel into a mold, parallel to the tundish bottom. Next, when the molten steel in the ladle is poured into the receiving steel bath region 3 by way of a nozzle 6, it flows in the tapping bath region 4 by passing the spacings between the shelves 5 and is poured into the mold 9 past the nozzle 7. At this time, the spacings between the shelves 5 are small and this enables the considerable reduction in the floating distance of the particles of the nonmetallic inclusions in the molten steel. Since the shelves made of refractory materials adsorb inclusion particles like slag, they have the effect similar to that when the contact area of the molten steel and slag is increased.

Title: Casting mold for continuous casting
Inventor: SHIRAI YOSHIHISA
IPC: B22D11/059
Filed: 1995-03-31
Abstract: PURPOSE: To prevent the dislodgment of thermally spraying particles by molten metal and powder by thermally spraying a refractory material mixed with specific ratios of ZrO2 , Al2 O3 , SiO2 and TiO2 to a casting mold. CONSTITUTION: The refractory material consisting, by weight %, of 30 to 80 ZrO2 and the balance Al2 O3 , SiO2 or TiO2 or a mixture composed thereof is prepd. This refractory material is thermally sprayed on the surface of the metallic casting mold, which surface comes into contact with the molten metal. The ZrO2 has excellent heat resistance and thermal impact resistance. The Al2 O3 , SiO2 or TiO2 or the mixture composed thereof lowers the m.p. of the ZrO2 to <=2000 deg.C, has the heat resistance and does not degrade the durability of the thermally sprayed layer. The use of the Al2 O3 is recommended if the heat resistance and wear resistance are regarded important. The selection of the SiO2 is recommended if the low m.p. is regarded important and the selection of the TiO2 is recommended if the wear resistance is regarded important.  Since the heating of the thermally spraying particles to the m.p. or above is possible, the bonding strength between the particles is intensified.

Abstract: PROBLEM TO BE SOLVED: To enhance workability of a fixing work at a site by making good use of an existing front pillar, by superimposing a light projector and a light receiver in a safety shoe actuating section and providing a reflector on an abutting side of the front pillar of a cage door. SOLUTION: An existing pillar is made good use of as it is for a front pillar 3 of a cage, and a mirror 8 of a reflector is labeled by a pressure sensitive double coated tape for instance to a front surface on one end side of a cage door 1 of the front pillar 3. A light projector 4 and a light receiver 2 are superimposed in a safety shoe actuating section 9 (hereafter called an actuating section) protruded for a certain distance L from a tip of the cage door 1. A modulated infrared ray signal 11 is sent toward the reflector 8 from the light projector 4, and the signal is received by the light receiver 2 through the reflector 8.  Since an existing pillar can be made good use of for the front pillar 3 of the cage, a work at a site can be simplified to a work only to remove the actuating section 9, to fix the light projector 4 and the light receiver 2 by a bolt 10 after inserting them in an internal cavity part, to fix the actuating section 9 to the cage door 1 and to fix the reflector 8 to the front pillar 3.

Filed: 1994-04-14
Abstract: PURPOSE:To provide a pulse amplifier that has a short settling time by providing a correction pulse generator to generate the correction pulse which is superposed on the pulse signal supplied to the pulse amplifier main body. CONSTITUTION:The digital data 3 and an enable pulse 4 are supplied to a D/A converter 1 and also to a correction pulse generator 6.
