Title: Comb-line filter
Inventor: NISHI HARUHIKO
IPC: H03H15/00
Filed: 1990-05-31
Abstract: PURPOSE:To reduce the cost of a comb line filter and to decrease number of components by applying frequency conversion to a signal delayed once, giving the result to a 1H delay line again and delaying the signal therein so as to provide only one 1H delay line. CONSTITUTION:The filter is provided with an adder 3 which adds an output of a high pass filter 2 and an output of a 1H delay line 4 subject to frequency conversion to a low frequency signal at a frequency converter 5, a high pass filter 6 which extracts a signal delayed by 1H from an output of the 1H delay line 4 and a frequency converter 7 which frequency-converts an output of the 1H delay line 4 into a high frequency signal and gives the result to a low pass filter 8. The inputted video signal passes through the 1H delay line 4 while not changing the frequency, the signal frequency is converted into a low frequency, the resulting low frequency signal passes again through the 1H delay line 4 and the signal is converted into the original frequency signal. Thus, the video signal passing through the 1H delay line twice is outputted from the low pass filter 8 and a signal passing through the 1H delay line 4 only once and a signal not through the 1H delay line 4 are obtained. Thus, the comb line filter is realized, in which one 1H delay line is used and similar effect is obtained.

Title: Production of quartz glass
Inventor: MIYASHITA SATORU
IPC: C01B33/152
Filed: 1984-07-12
Abstract: PURPOSE:To produce completely homogeneous quartz glass of high quality usable in an optical system, by filtering a sol through a porous filter, and gelatinizing the filtered sol. CONSTITUTION:In production of quartz glass from at least an alkyl silicate and an ultrafine powdery silica as raw materials by the sol-gel method, sol is passed through a fine filter having <50mu pore diamter once or more, and gelatinized. Thus, completely homogeneous quartz glass of high quality can be produced, and the resultant quartz glass can be used in an optical system and applied to quartz substrates for photomasking, quartz glass fibers for ptical communication, various optical cells, etc. The sol has a high viscosity, and is gelatinized by drying to make the filtering operation difficult. Therefore, a method for continuously filtering the sol with a liquid supply pump under pressure is very effective. The use of a coarser filter to a finer filter one after another is preferred since clogging is not easily caused.

Title: Manufacture of semiconductor device
Inventor: UMEMURA EIICHI
IPC: H01L21/26
Filed: 1987-06-12
Abstract: PURPOSE:To obtain a semiconductor device whose contact resistance value is less than that by a surface sintering process and whose defect is few by a method wherein a heat-treatment operation in a process to heat-treat a semiconductor substrate having an Al electrode wiring contact by using a lamp is executed at a temperature within a specific extent for a specific duration. CONSTITUTION:A heat-treatment operation is executed at a temperature of 400-450 deg.C for longer than 30sec. If a sintering operation is executed for an appropriate duration during a process to form an Al wiring contact, Al penetrates into a substrate and a resistance value is reduced; if the temperature is too high, Si is precipitated at the contact part and the resistance value is increased due to this precipitation. If the duration and the temperature extent are set appropriately in this manner, it is made possible to reduce the resistance value without precipitating the Si and to reduce a defect of the substrate.

Title: Method and apparatus for producing metal pipe clad optical fiber cable
Inventor: KAMATA SHOSEI
IPC: G02B6/44
Filed: 1991-05-22
Abstract: PURPOSE:To prevent an optical fiber from moving and deviating a prescribed surplus length at the time of adjusting tension by temporarily cooling a metallic pipe just before a traction device after a high-temp. gel is injected into the metallic pipe. CONSTITUTION:The high-temp. gel from a gel injecting pipe 7 is injected into an introducing pipe 6 and while the gel is packed into the metallic pipe, the optical fiber is delivered by the viscosity of the gel. The optical fiber is introduced and the metallic pipe packed with the gel travels through a cooler 18. The gels solidifies to a high viscosity and eventually holds the optical fiber securely in this position when the pipe is cooled down to a prescribed temp. during this time. The metallic pipe is thereafter pulled in such a manner that the tension thereof attains a prescribed value while the metallic pipe is wound by a capstan 12 which is a tension varying device. The position of the optical fiber in the metallic pipe is securely held by the solidified gel at this time and is prevented from biasing inward of the winding radius at the time of winding by the capstan. The surplus length is thus prevented from changing from the prescribed value when the metallic pipe is afterward stretched straight.

Abstract: PROBLEM TO BE SOLVED: To effect high accurate printing and to prevent the development of a defective solder bridge even after reflowing by obtaining a cream solder composed of powdery solder and liquid or pasty flux and adding a glycol base solvent and a hydroxystearic amide base compound in the flux. SOLUTION: In the flux of the cream solder in which the powdery solder and the liquid or basty flux are mixed, the hydroxystearic amide base compound N,N'-orefinebis (12-hydroxystearic amide) is incorporated as thixo-agent and further, glycol base solvent is incorporated. The amide base compound is one component base and stable compound and the material characteristic of viscosity, thixotropy index, etc., can be uniformized. Further, since the glycol base solvent has low viscosity, the vol. of the flux accepted in the cream solder is reduced and restrains the slump of the cream solder at the time of preheating and has such action as to prevent the solder bridge.
