Title: Ceramic package for semiconductor device
Inventor: UEDA MASAO
IPC: H01L23/50
Filed: 1990-05-16
Abstract: PURPOSE:To obtain a ceramic package which does not generate cracks of a ceramic substrate by means of the constitution in which outer lead pins are fixed with wax and implanted in the recessed part of a ceramic substrate. CONSTITUTION:Each recessed part is made at the portion of a ceramic substrate 1, where wax is applied for an outer lead pin 2. A metallized layer 3 is formed in the recessed part, and the outer lead pin 2 is fixed by waxing with wax 4 through the metallized layer 3. As a result, a space between one waxed metallized insulation layer and another layer 5 can be reduced by reducing the area of waxed portion. In addition, enough fixing strength can be obtained and generation of cracks of the ceramic substrate can be prevented.

Title: Time base companding method and device for audio signal
Inventor: FUJII SHIGEKI
IPC: G10L21/049
Filed: 1999-05-06
Abstract: PROBLEM TO BE SOLVED: To reduce an overall throughput practically without degrading quality of a final output. SOLUTION: An original digital signal to be time base companded is stored in a delay buffer 1 and waveforms adjacent in a time base direction is read while sequentially modifying its reference segment length by means of an adjacent waveform reading control part 2. A similarity calculating part 3 and a control part 4 judge similarities of adjacent waveforms and extracts a reference period of a waveform judged to have the highest similarity as a fundamental period of the original digital signal. A waveform reading control part 5 reads each data of waveforms shifted for just one fundamental period from the delay buffer 1. Time base companding means 6, 7, and 8 generate output signals time base companded at a specific companding rate and having no pitch fluctuation by deleting or inserting data of a waveform of one fundamental period.  The adjacent waveform reading control part 2 reduces evaluation targets of similarity judgment for reducing throughput by thinning out data of two waveforms to be compared in the time base direction and reading them from the delay buffer 1.

Title: Fuel assembly having molten fuel holder and reactor core using the same
Inventor: YANAGISAWA TSUTOMU
IPC: G21C9/016
Filed: 1977-10-21
Abstract: PURPOSE: To obviate a molten fuel from having a critical shape by providing a molten fuel holder so that the molten fuel may be held thereby.  
     CONSTITUTION: There is provided above an entrance nozzle 5 and below a bundle of fuel elements 2 a molten fuel holder 9 which is made of a material having a high melting point and which is formed with a number of longitudinal holes 8. If any accident takes place to increase the output so that the cover pippes of the fuel elements 2 which are accommodated in bundle in a fuel assembly 1 are broken to inject the molten fuel, most of the molten material falls down until it reaches the upper surface of the holder 9. Since the falling molten fuel has little fluidicity, most of it stays on the upper surface of the holder 9.
