Title: Preparation of silicon halide
Inventor: IWAI TADASHI
IPC: C01B33/08
Filed: 1982-03-25
Abstract: PURPOSE:To obtain a silicon halide from an inexpensive raw material at a relatively low reaction temperature industrially and advantageously in high yield, by reacting a mixture of a siliceous material with a carbonaceous material with a halogenating agent in the presence of metallic silicon. CONSTITUTION:A mixture of a siliceous material with a carbonaceous material is reacted with a halogenating agent to prepare a silicon halide. In the process, a small amount of metallic silicon, preferably in an amount of 0.03- 1pt.wt. based on 1pt.wt. SiO2 in the siliceous material is added to the reaction system to carry out the reaction. If the amount of the metallic silicon is too small, the heat of reaction released by the halogenation of the metallic silicon is too little. Thus, the quantity of heat, required for advancing the reductive halogenation reaction of the siliceous material smoothly, and fed from the outside is too much, and the effect of addition of the metallic silicon is insufficient. If the amount of the metallic silicon is too large, the cost of the raw material is high, and the temperature of the reaction system is unpractically increased more than required.

Title: Production of metallic cylinder
Inventor: MATSUZAKI HIKARI
IPC: B23K3/00
Filed: 1980-04-09
Abstract: PURPOSE: To make the spacing between end faces virtually zero and accomplish stable brazing of good airtightness by rounding a plate-shaped blank material, fitting and housing the same into a cylindrical frame jig of a small coefft. of thermal expansion and brazing the same.  
     CONSTITUTION: A platelike blank material 11 is rounded and a sheetlike brazing fillter metal 12a is held in place between the end faces 13 to be joined. The metal 12a is formed to have the width W 1  smaller than the width W 2  of the end face 13 of the rounded cylinder 11. This is fitted and housed in an outer frame jig 14 of a cylindrical shape. This jig 14 is made of a material, such as iron or graphite, which is smaller in the coefft. of thermal expansion and is harder to deform than the material 11 and is worked to have sufficient wall thickness and good roundness of bore. In this case, it is so designed as to provide an extremely slight spacing between both. When this is put into a heating furnace and is heated, the brazing filler metal melts and adheres to the jig. By the effect of the thermal expansion of the material 11, the spacing (t) between the end faces decreases and this exerts pressure upon the brazed part, thus permitting stable brazing. Next, it is cooled and the cylindrical product is taken out.

Abstract: PURPOSE:To measure the frequency characteristic of the amplitude without AGC operation and resetting of level diagram by devising a conventional interme diate frequency amplifier such that two kinds of time constants of the AGC loop are to be selected and adding a function to identify whether or not an input signal is a sweep signal. CONSTITUTION:A time constant section 4 having a standard time constant and a larger time constant, and a sweep signal identification section are added to a conventional intermediate frequency amplifier. With a signal wave given to the sweep signal identification section, the output of a pulse detection section 10 is a control output to select the 'standard time constant'. With a sweep signal given to the sweep signal identification section 5, the output of the pulse detection section 10 is a control output to select 'large time constant' while the sweep signal is being inputted. Thus, even when the AGC remains to be set, it is possible to measure the amplitude frequency characteristic by using a 50/60Hz sweep signal.

Title: Taper slot antenna
Inventor: SATO MASATO
IPC: H01P5/10
Filed: 1996-03-05
Abstract: PROBLEM TO BE SOLVED: To obtain a reflecting characteristic over a broad band by forming a notch that is formed by removing a ground conductor in a shape to have a bent in nearly axis symmetry with respect to a rotation symmetrical axis at a position of a taper slot line on a ground conductor face in nearly axis symmetry with respect to the rotation symmetrical axis. SOLUTION: At a lower frequency band where a width W of an open end of a taper slot line 6a is less than 1/2 wavelength, a current path along a line 6a is extended up to an end of a notch 7a via a folded part from an open end of the line 6a so as to concentrate a current not attenuated in the vicinity of the open end of the line 6a onto a folded part of the notch 7a and to attenuate sufficiently the current at the end of the notch 7a thereby forming a traveling wave current distribution along the vicinity of a line 6a. Thus, a current flowing along the vicinity of the line 6 on a ground conductor plane 3a is not attenuated in the vicinity of the line 6a but attenuated at the end via a bent of the notch 7a. That is, the bent acts like an antenna.

Title: Heat insulation inner wall panel
Inventor: KOTANI MIKI
IPC: E04B1/80
Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To simplify execution by sticking a moisture-proof sheet on the outer peripheral face of a wood backing frame framed in a rectangle, and sticking an insulator out of the wood backing frame on the outer face side of the moisture-proof sheet. SOLUTION: A moisture-proof sheet 3 is stuck on the outer peripheral face of a wood backing frame 2, and an insulator 4 is stuck on the outer face side of the moisture-proof sheet 3 to make an insulation inner panel 1. The insulator 4 does not exist in the frame of the wood backing frame 2 according to the insulation inner wall panel 1, and since the frame inside is a void, the insulator is simply fixed on a floor backing material by driving a nail. Since a wiring hole 20 is provided in a middle rail 23 in the void, wiring is inserted in the hole 20 and can be freely handled. In this case, the sheet 3 and the insulator 4 are stuck on the outer face side of the frame 2. Thus, when wiring work such as attaching of a plug socket is performed, the wiring can be handled in the frame without breaking the sheet and the insulator.
