IPC: C23C14/24
Filed: 1990-01-24
Abstract: PURPOSE:To deposit metal vapor on the surface of a metallic material at atmospheric pressure at a high rate in vapor-deposition plating by using a burner flame in a specified air-to-fuel ratio or the jet of a heated inert gas as a carrier. CONSTITUTION:A plating material is melted in a metal melting furnace 4. A burner flame 5a in air-to-fuel ratio of <1 is injected from plural burners 5, and a steel sheet 2 is passed through a vapor-deposition chamber 1. The flame collision part on the surface of the sheet 2 is heated by the flame 5a, and the chamber 1 is filled with a nonoxidizing atmosphere. The metal vapor diffused above the furnace 4 is joined to the flame 5a and heated by the flame 5a. The vapor is allowed to collide with the entire surface of the sheet 2 along with the flame 5a in the nonoxidizing atmosphere, and the sheet is continuously plated. An inert jet heated to >=1000 deg.C is also used as the carrier as well as the flame 5a.

Title: Electrolyte plate molding tool for molten carbonate fuel cell
Inventor: SHINOZAKI KAZUO
IPC: H01M8/02
Filed: 1984-01-31
Abstract: PURPOSE:To improve the mechanical strength of an electrolyte plate and its adhesion with each electrode by forming an electrolyte plate uniform in relative density and thickness without using any release agent with the use of a molding tool, consisting of boron carbide, silicon nitride, aluminum nitride, silicon carbide, or graphite, to make electrolyte plates. CONSTITUTION:Boron carbide, silicon nitride, aluminum nitride, silicon carbide, and graphite are chemically very stable to carbonate, and have a good thermal conductivity and a small thermal expansion coefficient. Therefore, by using these materials, a hot-press type molding tool, consisting of a loop frame 1 plus an upper press plate 2 and a lower press plate 3 (these press plates 2, 3 fitting into the frame 1 from above and under respectively as shown in the figure), was formed, and when the mixed powders of gamma-LiAlO2, Li2CO3, and K2CO3 were hot-pressed with this molding tool, the uniform temperature was gained over the molded surface at the time of hot-pressing. In this way, the electrolyte layer produced is uniformed in relative density through the uniform melting and flowing of carbonate, and thus the mechanical strength of electrolyte plates can be heightened.

Title: Ic tester
Inventor: MIZUTANI YOSHIYUKI
IPC: G01R31/26
Filed: 1990-01-26
Abstract: PURPOSE:To simultaneously and efficiently measure the different kinds of ICs by providing the IC tester with a mask memory for storing mask information for masking defective information in a fail register in each item correspondingly to each IC. CONSTITUTION:The IC tester is provided with the mask memory 22 for storing mask information M1 to Mn for masking defective information in the fail register in each item correspondingly to each IC 1. When a different sort of an IC is used even if a certain IC corresponding to a certain test item is decided as a defective one, AND between the defective information in the fail register and the mask information in the mask memory 22 is regarded as a defective signal. When mask information is applied to the IC decided as a defective one in a certain test item, the next test item is processed without accepting a defective signal corresponding to the test item concerned. Since an IC which does not require a certain test item can skip the test item, different sorts of ICs can be simultaneously measured.

Abstract: PURPOSE:To reduce a coding noise, and to improve the quality of a picture by providing a means to detect the moving amount of a video signal, the means to output cut-off frequency, a lowpass filter, and the means to execute the encoding processing of the band-limited video signal. CONSTITUTION:A motion detector 101 detects and outputs the moving amount 106 of each picture of the video signal 105. A cut-off frequency outputting device 102 outputs the low cut-off frequency 107 if the moving amount 106 is large, and outputs the high cutoff frequency 107 if the moving amount 106 becomes small. Besides, the low-pass filter 103 bnad-limits the video signal 105 by the cut-off frequency 107. Then, an encoder 104 executes the encoding processing of the video signal 108 having been band-limited by the low-pass filter 103, and obtains a code string 109. Thus, the video signal of the large moving amount is band-limited by the low-pass filter of the low cut-off frequency.

Title: Semiconductor structure and semiconductor device
Inventor: TSUCHIYA TOMONOBU
IPC: H01S5/00
Filed: 1991-02-06
Abstract: PURPOSE:To obtain a semiconductor structure where the strain quantity and a thin film of a strain layer are controlled independently by a method wherein a matching layer provided between a substrate and at least two strain layers different in lattice constant has a band gap energy equal to that of the strain layer and makes lattice match with the substrate. CONSTITUTION:Strain layers 1 of a critical film thickness or less and a matching layer 2 which makes lattice match with a substrate are provided alternately to constitute a strain well layer 4'. In this way, the strain layer is divided by the matching layer to increase the strain quantity added in the strain well layer. An alternate way is to make the strain layer of a quarternary crystal, the matching layer of a binary or ternary crystal, or both of a quarternary crystal, resulting in a change in its mixed crystal ratio. Thus, the band gap energy in the strain well layer is made equal to that of the strain layer 1 at the matching layer 2 to change only the strain quantity. This process can provide a semiconductor structure where the stain quantity and the film thickness of a strain layer are controlled independently.
