Title: Tip holder in electric resistance welding device
Inventor: MOCHIZUKI TADAAKI
IPC: B23K11/14
Filed: 1997-11-12
Abstract: PROBLEM TO BE SOLVED: To sufficiently bulge a joining part at the time of electrically heating and to improve the soundness by arranging a taper hole continued to a holding hole and enlarging the diameter upward at the upper part of the holding hole of a tip holder for holding a tip joined to the lower end surface of a rod-like work so as to be freely attached/detached and placing the lower end of the taper hole at lower level in the tip thickness. SOLUTION: At the time of projection-welding the wear resistant tip 3 to the end part of shaft part 2 of an engine valve 1, the tip holder 16 has the tip holder hole 16a having the larger diameter by a little than the valve shaft part 2 and forms the taper hole 16b enlarging the diameter upward. Further, the lower end position of the taper hole 16b continued to the holding hole 16a is made to the height of almost 1/3 of the tip 3 thickness so as to position to remarkably lower part from the joining surface of the valve shaft 2. By this constitution, the joining part at the time of press-welding can largely be bulged outward along the inclining hole 16 and the development of a little gap on the outer peripheral surface of the shaft appeared at the time of cutting the bulged part can be prevented.

Title: Semiconductor light emitting element
Inventor: MIHASHI HIROSHI
IPC: H01L21/365
Filed: 1988-12-09
Abstract: PURPOSE:To obtain a blue emitting light having high intensity by incorporating Li impurity in the P-type layer of a P-N junction light emitting element made of a zinc chalcogenide semiconductor, and incorporating a superlattice structure in the N-type layer. CONSTITUTION:A blue semiconductor light emitting element is composed of a p-type GaAs single crystalline substrate 11, a P-type ZnS0.06Se0.94 layer 12 and an N-type strain superlattice layer 12 made of 100 layers of ZnSe layers 13a and ZnS0.12Se0.88 layers 13b. The average sulfur composition of the strain superlattice layer 13 is 0.06. Since the GaAs substrate 11 and the ZnS0.06Se0.94 layer 12 thereon are lattice-matched as the whole superlattice layer 13, the deterioration of element characteristics scarcely occurs. Li is doped in the ZnS0.06 Se0.94 layer 12 as a P-type and Br is doped in the ZnSe-ZnS0.12Se0.88 layer 13b as an N-type. An In-Zn electrode 14 is formed on the surface of the substrate 11, and an In-Ga electrode 15 is formed on the layer 13b.

Title: Basic refractory
Inventor: SHIMIZU KOICHI
IPC: C04B35/043
Filed: 1998-10-30
Abstract: PROBLEM TO BE SOLVED: To obtain a basic refractory having improved tolerance without including Cr2O3 by adding a small amount of an oxide of a rare-earth metal to a basic refractory raw material. SOLUTION: A basic refractory raw material having especially >=95 wt.% MgO content is preferable with respect to corrosion resistance to slag. A magnesia clinker partially or wholly substituted with a magnesia-calcia clinker can be used as a basic refractory raw material comprising MgO and CaO as main components. The refractory has a texture in which an oxide of rare-earth metal exists mainly in the matrix of brick. Consequently the oxide of rare-earth metal is reacted with SiO2 in a slag to raise the melting point of the slag and to control permeation of slag. Y2O3, La2O3, etc., are used as the oxide of the rare- earth metal and its blending ratio is properly about 0.2-20 wt.%. In the case of the oxide of the rare-earth metal comprising >=50 wt.% Y2O3, the basic refractory shows especially excellent corrosion resistance and hot strength.

Title: Transmission error detection circuit
Inventor: KOBAYASHI KAZUSHIGE
IPC: H04L1/00
Filed: 1986-12-30
Abstract: PURPOSE:To directly detect transmission errors from ON/OFF digital signals by comparing an output signal from a delaying/inverting circuit with an original received digital signal at a comparator, and discriminating the periodicity of output signals from this comparator. CONSTITUTION:A received signal is inverted by an inverse logic circuit 1, slightly delayed by a delay circuit 2 in terms of time, and inputted to an AND circuit 3. To the other input terminal of the AND circuit 3, the reception signal is inputted as it is, and the AND condition of both input signals is detected, and an output signal from this AND circuit 3 is transmitted to a monitoring device 4 where its periodicity is discriminated. A digital signal is a signal constituted of a combination of turning on and off, therefore, even if the turning on/off is continued, they maintain the periodicity which is the multiple of integer of basic period. Hence, by monitoring the periodicity of the signals representing the timing of the leading and trailing of received digital signals, the absence of errors can be discriminated when the periodicity is detected and the presence of errors also can be discriminated when the periodicity is irregular.
