Title: Thin-film transistor and manufacture thereof
Inventor: KUMANO KATSUFUMI
IPC: H01L21/336
Filed: 1986-02-18
Abstract: PURPOSE:To obtain an a-Si thin-film transistor with a structurally extremely stable gate insulating film by using silicon as constituent atoms in the gate insulting film, bringing content in the film of hydrogen to 0.1atom% or less and bringing the dielectric withstanding voltage of the gate insulating film to 8MV/cm or more. CONSTITUTION:With a gate insulating film 102, silicon is employed as constituent atoms, content in the film of hydrogen is brought to 0.1atom% or less, it has a composition containing oxygen and nitrogen as additives and dielectric withstanding voltage thereof is brought to 8MV/cm or more. An a-Si:O:N(H) film is used as the gate insulating film 102, and the film is shaped by applying a plasma CVD method. Gases are reacted as shown in SiH4+CO2 SiOx(H)+CO, SiOx(H)+N2 SiOxNy(H)+H2. In SiOxNy(H) acquired by the reaction, an extreme trace quantity of hydrogen is contained in the film, and hydrogen as the unstable factor of the film hardly having an effect substantially in the quantity. Dielectric withstanding voltage is also an essential factor as the gate insulating film. The dielectric withstanding voltage of the a-Si:O:N(H) film by this invention is 9MV/cm, and characteristics approximately equal to a thermal oxide SiO2 film are acquired.

Title: Decanter
Inventor: NISHIMOTO KOREHIKO
IPC: B01D17/02
Filed: 1979-03-19
Abstract: PURPOSE: To facilitate in a decanter separation of heavy liquid phase suspended in light liquid phase, the bottom of the container is provided with a mechanism for dispersing mixture, the intermediate part with porous layer for separating heavy and light liquid phase, the top with light liquid discharge line, and the lower part of porous layer with heavy liquid discharge line.  
     CONSTITUTION: Liquid mixture 8 is injected through the particulating nozzle 1 located at the lower of the decanter and dispersed into droplets. The droplets are passed through perforated plates 2 and current-contacted with salt-containing heavy liquid phase 11 which is circulating. The salt effect reduces mutual liquid solubility to cause the mixture to be separated into two liquid phases. The heavy phase is extracted from the dispersed droplets and united in one phase which is trapped by the main flow of liquid. The light phase droplets removed from the heavy phase are passed through the filler layer 3 forming combined liquid body, and goes to the top. The light liquid level is controlled by the detector 5 that opens and closes the valve 5.

The synchronous stage consists of a synchronous controlling circuit 14 and a bit replacing circuit 16. The circuit 14 creates more than one synchronizing voltage signal VA which shows a time when the value of the 1st set of bits B0 to BK-1 is close to the value of an input value V1 . When one of VA signals instructs it about one bit of the 1st set, the replacing circuit 16 replaces the present value of the bit with information that is derived from the 2nd set of bits. Then, the circuit 16 offers a set of K bits B0 ', B1 ',...BK-1 ' which synchronize with the 2nd set of M-K bits.

Title: Electrophotographic toner
Inventor: MAKUTA YOSHIHIRO
IPC: G03G9/087
Filed: 1982-03-02
Abstract: PURPOSE:To improve an electrophotographic toner, by using a resin mixture contg. a norbornene polymer as a binder resin. CONSTITUTION:Polynorbornene obtd. by ring opening polymn. of bicyclo 2,2,1  heptene-2 is embodied as a binder resin, and the norbornene polymer has a  small rate of viscosity drop in relation to temp. rise as compared with ordinary toner resins and low stickiness of the melt. Since the cohesion of the toner itself becomes stronger than that of the adhesion of the toner to the roll in fixing, the toner hardly tends to stick to the roll. The other resin to be mixed with said resin is, preferably, a styrene resin from the view point of compatibility. A pigment or a dye can be added to the toner in a concn. enough to form a clear visible image on a recording material. In addition, other additives may be added to enhance kneading dispersibility and crushability.

Abstract: PROBLEM TO BE SOLVED: To facilitate welding work and visibility of weld part by outwardly bending an edge part to be welded to the internal surface of a valve main body of a straightening vane in a valve and welding the edge part to the internal surface of the valve main body. SOLUTION: A straightening vane 2 in a valve is formed in a channel groove shape, and the both vane edge parts 2e to be welded to a valve main body 1 are formed so that they are bent outward.
