Abstract: PURPOSE:To enhance the reliability and withstand voltage of a semiconductor device by patterning an SiO2 film formed by a CVD method so as to remain in advance only at the film formed on an Si substrate outwardly located from a base region and then performing a densifying treatment. CONSTITUTION:An SiO2 film formed by the thermal oxidation of the prescribed pattern is formed on an Si substrate 1, and with the film 2 as a mask, a base region 3 is formed. Then, with the film 2 as a mask an emitter region 4 is formed. Subsequently, an SiO2 film 5 is formed by a CVD method on the overall surface of a substrate, and the film 5 formed by the CVD method on the base region 3 is removed. The substrate 1 is heat treated at 900 deg.C in oxygen atmosphere in this state for 2-3hr to perform the densifying treatment. In this manner, the SiO2 film on the region 4 becomes a layer structure of the film 2 by a thermally oxidizing method. Accordingly, no crack is produced at the SiO2 film, and therefore the film 2 is prevented from being isolated from the substrate 1.

IPC: H04L27/38
Filed: 1993-01-29
Abstract: PURPOSE: To precisely identify whether a packing bit and a deleting bit are a customer bit or an auxiliary bit by differentiating a framing bit for identifying each frame from any data symbol. CONSTITUTION: Each frame includes prescribed number of framing bits and the frame is distinguished from the others by the using of a framing bit inserted to each frame by a transmission part 105.

A customer data bit is connected with a lead 110 within a receiving part 108 within a center station 102. The data rate of a customer data bit transmitted through the lead 110 is r1 . However, the loop 107 bi-directionally provides communication at a data rate r2 and does not synchronize with the rate r1 . In addition, a customer data bit supplied onto a lead 114 from a lead 112 is provided a data rate r3 and does not synchronize with the rate r2 .

Title: Vertical wet type granulator
Inventor: YUSA MITSUO
IPC: B01J2/10
Filed: 1979-03-20
Abstract: PURPOSE: To efficiently convert fine suspended material into high-density blocked coagulated body, by a method wherin suspended liquid and high-moledular coagulant are charged into a tank and rotary blade is rotated to allow the liquid in the tank to repeat uprising and falling whirl motion.  
     CONSTITUTION: Suspension liquid is supplied from inlet pipe 2 into the tank 1. At the same time, a proper amount of high-molecular coagulant is injected from inlet pipe 3. Drive mechanism 8 rotates rotary blade 10 to revolve and move the liquid upward in the riser section 6 and downward in the down comer section 7. This causes circulating liquid flow in the tank to permit suspended material in the liquid to mutually collide in floating condition and to undergo contact and rolling motion, gradually forming into coagulated blocks. Such coagulated blocks grow to some size, then collapse into smaller coagulated block group, and are efficiently overflowed from outlet 4 outside, together with separated water.

IPC: H01F10/16
Filed: 1985-02-22
Abstract: PURPOSE:To decrease considerably the variable of magnetic characteristics by laminating alternately >=2 layers of thin Co films and thin Pt films to form a laminated film and subjecting thereafter the laminated film to a heat treatment. CONSTITUTION:Co and Pt are successively deposited by evaporation to 70nm the former and 30nm the latter onto a substrate consisting of glass, alumina, Al subjected to surface oxidation, Ti, etc. Such Pt/Co two-layered film is heated for 1-3hr to 300-500 deg.C in a vacuum or inert atmosphere. Co and Pt induce the diffusion with each other and have the mixed state from the boundary between the two when subjected to the heat treatment. The coercive force of the thin film exhibits the max. value when the compsn. of both in a mixed region attains Co-10-30%Pt. The compsn. of the reactive layer changes with the film thickness of Pt and the temp. and time of the heat treatment. The compsn. distribution in the depth direction of the formed thin film permanent magnet is made uniform or nonuniform by changing systematically the above- mentioned factors.

Title: Gas concentration measuring instrument
Inventor: HISHIKARI ISAO
IPC: G01N21/61
Filed: 1994-02-04
Abstract: PURPOSE:To enable a gas concentration measuring instrument to measure the concentration of a gas with high sensitivity by repeatedly reflecting radiation energy by using window sections respectively provided with transparent parts and reflecting parts provided on both internal surfaces of a container facing each other. CONSTITUTION:Radiation energy L from a radiation source 4 is made incident to a container 1 through the peripheral transparent part 22 of a window section 2 and reflected by the peripheral reflecting part 32 of a window section 3 on the opposite side. As a result, the energy L arrives at the central reflecting part 21 of the window section 2 after reversely advancing in the container 1 and reflected by the central reflecting part 21 of the window section 2. The reflected energy L reaches the central transparent part 31 of the window section 3. Therefore, the length of the optical path becomes triple as compared with the conventional example, because the energy L advances in the container 1 three times in the length direction. The light which is tripled in absorption is made incident to a detecting element 7 after passing through a filter 51 and being condensed through a lens 6. The filter 51 is adjusted to a measuring wavelength so that the filter 51 can pass the light having a characteristic absorption wavelength and a measuring means 8 measures and analyzes the concentration of a gas.
