Patent JP-S6141135-B2 (JP)
IPC: H01L21/58
Filed: 1979-11-30
Abstract: A solder joint between a semiconductor substrate and an electrode is disclosed in which that principal surface of the semiconductor substrate where an n-type semiconductor layer is exposed is bonded to the electrode with brazing solder, and the brazing solder includes aluminum solder provided on the side of the semiconductor substrate and copper solder provided on the side of the electrode. Since solid phase adhesion can be achieved between aluminum and copper even at temperatures below an eutectic temperature of 548 DEG  C., the semiconductor substrate can be soldered to the electrode at the low temperatures.

Abstract: PURPOSE:To fix glass plates and a sealing compd. for double-layered fittings without position deviations, by forming meltable plastic layers respectively on the inside surfaces of the glass plates and the surfaces of the sealing compd., pasting these together by means of an adhesive agent and melt sticking both resin layers to each other. CONSTITUTION:A meltable plastic layer 2 is formed on the inside circumference of a glass plate 1 and meltable plastic layers 4 are formed on both sides of a sealing compd. 3 such as butyl rubber or the like as well. The plastic layer 4 on the bottom surface of the sealing compd. 3 is superposed via an adhesive agent on the layer 2 of the plate 1 and the layer 2 of the other plate 1 is superposed via the agent 5 on the layer 4 on the top surface of the sealing compd. 3, whereby these are set to the shape of double layered fittings. After such double layered fittings are temporarily held by the adhesion strength of the agents 5, laser light or the like is irradiated from above the plate 1 to melt the layers 2, 4, thereby fixing the plates 1 and the sealing compd. 3 to one body.

Abstract: A jointing machine for the folding of seams in manufacturing of seamed metal sheets made of segments of metal sheets is disclosed, wherein the machine includes a locking wheel pivotably positioned in a recess of a resiliently disposed locking wheel carriage. The seam during formation is supported from below by a support roller, and is held from the sides by an adjustment roller together with the locking wheel. The locking wheel carriage is positioned diagonally relative to the surface of the support roller, which enables the machine to manufacture folded seams in very small metal sheet segments, and to utilize thick or hard metal sheets. The particular arrangement of the jointing machine of the present invention which respect to the locking wheel carriage diagonal positioning enables the locking wheel to penetrate even restricted spaces, and the folding of the seam can be accomplished in several steps wherein the use of the locking wheel carriage ensures the transmission to the seam of sufficient force to form a strong folded joint.

Abstract: Transistors (10) having lateral gaps between their source and drain and the gate are interconnected in a ROM to receive program code.In one embodiment of the invention (Fig. 3), the gaps of selected transistors (42) are subjected to a phosphorous implant (44) to create lightly doped n⁻ regions (26,28) connecting the source (18) and drain (20) to the gate (14), and function normally. The other transistors (40) do not receive the phosphorous implant, and thus have a higher threshold voltage.In another embodiment of the invention (Fig. 2) all of the transistors receive the phosphorous implant to create the n⁻ regions (26,28) connecting the source and drain to the gate, and the n- regions of selected transistors (32) are counter-doped with a boron implant (34) so as to raise their threshold voltages, while the other transistors (30) are not counter-doped and function normally.In both embodiments, programming can occur late in the processing of the ROM.

Abstract: Before transmitting print data, a print controller transmits to a printer information on a thickness of a printing medium corresponding to a sort of printing medium which is selected on a select screen by an operator in a state that the medium thickness information is contained in control data for the print data. In the printer, a timing correction section corrects a timing of ejecting an ink drop onto a printing medium in the forward and reverse scans executed by the recording head in accordance with the control data containing the medium thickness information. Accordingly, stress imposed on the operator when the printer prints on various types of printing media in a bi-directional printing mode can be reduced. <IMAGE>

Abstract: A packet switched communication system employing ANR and/or multicast tree routing is improved by using a Copy ID field in the network header of the packet. The Copy ID field defines a control function and allows packet processing to be distributed among the several processors of each node. The selection of the processor (or processors) to receive the packet may be accomplished by making use of the routing field of the network header to qualify the control function specified in the Copy ID field. The control message is processed as defined for the control function by the processor receiving the packet. In multicast tree routing the control function is performed at all nodes in the multicast tree. In ANR routing, a prefacing "selective copy" bit is included in each label in the routing field of the network header; each node employed in the packet transmission path uses one label. The selective copy bit in each label triggers or not (according to its setting) the copy function in that node. The network control function specified in the Copy ID field may be performed in a given node when the copy function is triggered for that node. <IMAGE>

Abstract: An adaptive method for channel assignment in a cellular multiple access wireless communication system that has a cell station (CS) and a number of subscriber stations augments existing channel assignment protocol and thus is downward compatible with existing time division multiple access (TDMA), frequency division multiple access (FDMA), code division multiple access (CDMA), and spatial division multiple access (SDMA) system protocols. The method adaptively determines the power required for establishing an acceptable quality connection between a subscriber station and the cell station and provides an early warning trial signal for advising existing connections that a new connection is about to be established. The early warning, followed by a pause, provides a basis and a time interval for taking corrective interference action if the trial signal indicates that an unacceptable level of interference will result if the trial connection is established. The early warning signal and associated pause are useful for intracellular and intercellular interference management.
