Patent JP-H06267968-A (JP)
Title: Manufacture of semiconductor device
Inventor: IIZUKA NORIO
IPC: H01L21/331
Filed: 1993-03-15
Abstract: PURPOSE:To enable a high base concentration and a low recombination current to be compatible by dividing the growth temperature of the layers above a base layer into two stages, and growing the layer part contacting with the base layer at a growth temperature relatively higher than the other portions. CONSTITUTION:In a semi-insulating GaAs substrate 11, layers 1 to 3 are grown by molecular beam epitaxiy at a growth temperature of 580 deg.C, respectively. Then, a base spacer layer 4 is grown at a temperature of 620 deg.C. Subsequently, layers 5 to 8 are grown at a temperature again decreased to 580 deg.C, respectively, and finally layers 9 and 10 are grown at 450 deg.C, respectively. This decreases the concentration of the recombination center where recombination occurs most frequently, and the recombination current can thus be reduced. In addition, since the growth temperature of the region other than necessary is made relatively low, a highly concentrated base layer can be formed without a fear for diffusion of the base dopant.

Abstract: PURPOSE:To realize the safe transportation and short term of assembling work by a method wherein the condenser is assembled up to the state as near as possible to reach completion at the factory and then divided into the sizes capable to transport on road especially with the condition to eliminate the requirement to weld cooling tubes at the site of installation of the condenser. CONSTITUTION:The cooling tubes 21, which constitute the cardinal part of the condenser, have been attached in a main shell 11 by welding under the state that no more welding is necessary. Tube supporting plates 17 and reinforcing plates 19 and the like also have been attached similarly in the main shell 11. A condensate reservoir 12, an upper shell 2 and a connecting shell 13 are respectively sent separately from the main shell 11. Partition plates 14 are divided in corresponding to the longitudinal division of the main shell 11 and transported by being fixed to the bottom of the respective main shells 11. Because the partition plate 14 equipped with the function as the roof plate of the condensate reservoir 12 is fixed to the bottom of the main shell 11, the partition plate 14 performs the duty of the transportation bottom plate of the main shell 11, resulting in eliminating the need for adding reinforcing member in extra and enabling to safely transport the main shell 11 as it is. Because no welding work of cooling tubes is contained in the assembling work by welding said divided parts, the assembling work is technically easy and a few amount of welding work and the short term of assembling work are resulted.

Filed: 1981-04-10
Abstract: PURPOSE:To allow the high-frequency operation of a GTO thyristor, by constituting an auxiliary thyristor with dv/dt quantity high-resistance in parallel in  the main thyristor part controllable for large current. CONSTITUTION:A low-resistant burried layer P2<++> of a proper pattern such as a lattice shape is formed in a P2 layer of a PNPN structure as a burried gate with space density of this P2<++> layer increased more than that of the main thyristor part SM by the auxiliary GTO thyristor part SA to improve SA cut-off for dv/dt quantity high-resistance. Then, in the process of turn off by the main thyristor SM and auxiliary thyristor SA, load current is transferred from SM to SA finally to cut-off the load current at SA. Thus, the condenser and resistance capacities of a snubber circuit are reduced to allow the high-frequency operation of the GTO thyristor.

Filed: 1996-02-15
Abstract: PROBLEM TO BE SOLVED: To enable quick detecting of an abnormality and stopping of a laser beam machine when an unexpected accident, such as the development of a hole in a billows, happens, by arranging a lead wire in the bellows. SOLUTION: The lead wire 9 is formed at each corner part of the bellows 1. Then, the bellows 1 is fitted between a beam path duct and a machining head of the lead beam machine 20 and also, the one end 9a of the lead wire 9 is connected with the one side of terminal 20a arranged at the laser beam machine 20 and the other end 9b is connected with the other side of terminal 20b to use the bellows.

Title: Method of cutting insulation pipe
Inventor: TAKEGAWA SEIJI
IPC: B28D1/24
Filed: 1990-03-06
Abstract: PURPOSE:To prevent the occurrence of cracks in the inner surface of an insulation pipe by effecting inner diameter cutting from the inside of an insulation pipe to the midportion of a wall thickness of the insulation pipe and, thereafter, also effecting outer diameter cutting in correspondence with the inner diameter cutting position from the outside of the insulation pipe. CONSTITUTION:An inner diameter cutting grindstone 4 is set on the predetermined position in the inner part of an insulation pipe G and, by outwardly moving the inner diameter cutting grindstone 4 in the radial direction while rotating the insulation pipe G, inner cutting is effected from the inside of the insulation pipe G to the midportion of a wall thickness thereof. Next, the inner diameter cutting grindstone 4 is removed from the inside of the insulation pipe G and an outer diameter cutting grindstone 2 is put into contact with the position of an outside of the insulation pipe G corresponding to the inner diameter cutting position and, in this state, outer diameter cutting is performed from the outside thereof. In this fashion, when a cut-in tip of the outer diameter grindstone 2 approaches the inner diameter cutting part, cracks may happen in the insulation pipe G. However, the cracks C are relatively small in size because they occur in the inner part of a wall thickness of the insulation pipe G and, since the direction is nearly in a direction of the wall thickness, moreover, the insulation pipe G is cut previously from the inner diameter side, the position where cracks C occur can be predicted exactly. Accordingly, the insulation pipe can be cut efficiently from the correct position.
