Title: Plasma cvd method and device therefor
Inventor: KADOMURA SHINGO
IPC: H01L23/522
Filed: 1994-05-31
Abstract: PURPOSE:To flatten the surface of a substrate to be treated by cooling the substrate in a plasma CVD chamber below the dew point of the deposition species by a substrate stage cooling means and irradiating the substrate with helicon wave plasma. CONSTITUTION:A substrate stage 2 is provided coaxially with a bell jar 5 in a CVD chamber 15. A substrate 1 to be treated is placed on the stage 2 and cooled by a cooling means 3. The deposition species is supplied on the substrate 1 from a second gas showering 14, liquefied and condensed. A gas supplied to the bell jar 5 from a first gas showering 13 is converted into the reaction species by the helicon wave plasma formed by the helicon wave antenna 6 and solenoid coil assembly 9, and the reaction species is injected into the substrate 1. The deposition species and reaction species are alternately injected to apply plasma CVD. The liquefaction and densification are alternately and continuously applied, and the substrate surface is flattened. A dense and good- quality film is formed in this way.

Title: Clarifying filter
Inventor: KATAOKA KATSUYUKI
IPC: B01D29/62
Filed: 1978-09-26
Abstract: PURPOSE: To obtain the stable treating performance with simple constitution, by filtering the raw water with the water permeable porous medium, and next, by filtering the filtrate water with the granular filter medium layer.  
     CONSTITUTION: The raw water flows from the influent pipe 16 into the water inflow zone 5, and is passed through the filter surface of the porous water permeable medium 2 in order to separate the SS of comparatively large particle size included in the raw water; and then, the filtrate (the primary filtrate) flows into the clarification zone 6. This primary filtrate overflows from the partition wall 4 of the clarification zone 6 and falls on the granular filter medium layer 8, and passes the layer 8 as the down current; hereby, the fine SS is removed and thus obtained filtrate (the secondary filtrate) flows out of the treated water effluent pipe 17. As the water permeable porous medium 2, the filter cloth, the pile of nap length about 1W10cm for example other than the ordinary filter cloth is more desirable in consideration of the SS removal performance, the filtration resistance, and the easiness of washing.
