Title: Vertical continuous high temperature heating furnace
Inventor: HAYASHI TATSUO
IPC: F27B9/00
Filed: 1988-02-08
Abstract: PURPOSE:To make it possible to operate a furnace continuously for a long period by a series of operations consisting of supplying heat-resistant vessels filled with material to be treated from the top of heating furnace care tube passing through furnace body, giving them heat- treatment while they are kept within an optimum temperature range and for an optimum time, and then taking them out of the bottom of core tube after the treatment has finished. CONSTITUTION:When controlled atmosphere is brought in via the gas supply port 7 of an elevator 17, the gas goes up through draft holes 25 as it fully penetrates into all the loaded heat-resistant vessels 10, and is discharged out of the furnace through a draft tube 7'. The heat-resistant vessels filled up with material to be treated are brought into furnace core tube 2 one after another by operating a supply mechanism 11 and a supporting and takeout mechanism 16. In other words, the heat-resistant vessel 10a in the lowest position is taken out to a position at the same level as a shelf provided at the furnace bottom by operating vertical transfer mechanism 15 and elevator 17 in mutual collaboration, and a rod of a feeder 18 is moved forward, which enables the upper face of arm 21 shaped like a 'U' to support the upper vessel 10b, to hold the vessel 10a taken out of the furnace by the arm front, and then to carry it out on the shelf 19. Subsequently, supporting board portion 20 is lifted through the gap of the U-shape arm 21 and supports the upper vessel 10b, and the arm 21 is sent back from the furnace bottom to the original position by moving the rod of the feeder 18 backward.

Title: Gaas integrated circuit
Inventor: TOYODA NOBUYUKI
IPC: H01L27/06
Filed: 1982-02-22
Abstract: PURPOSE:To reduce series resistance, to lower current saturation voltage and to realize the high-speed GaAsIC by using a current limiter, in which the width of two ohmic electrode sections is wider than that of a region in which electrons travel at the speed of saturation, as load. CONSTITUTION:The electrically active region L, in which electrons travel at the speed of saturation, and two wider regions L' connected electrically to the region are formed, the ohmic electrodes 33 are formed to the regions L', and the current limiter is used as load. Consequently, since the series resistance (Rs) of the current limiter is small, saturation voltage Vs can be reduced. Accordingly, the limiter functions as constant-voltage load even when line voltage is low as approximately 1V, and the high-speed and stable GaAs IC can be constituted.
