Title: Liquid oxygen-free treating method
Inventor: HOFFMANN CLALENCE A
IPC: C02F1/28
Filed: 1986-08-25
Granted: 1993-03-06
Abstract: A process for the treatment of high strengfh BOD containing liquors (1) involves mildly mixing and contacting the liquors with anaerobic bacteria (2) and a powdered adsorbent support medium (4), such as activated carbon, to remove a substantial portion of the organic matter and generate a methane fuel gas (3). Use of the powdered support medium at 0.1-20 g/l enables high removal of BOD in short treatment times of 72 hours or less, rapid clarification of treated liquors, and increased adsorbability of liquor colour. The biomass and adsorbent support medium (8) is separated from the digested liquor (7) and at least part (9) thereof is returned to the anaerobic digester (2). Another part (11) may be treated to regenerate the support medium (13) for re-use. The digested liquor (7) may be further contacted with reduced concentrations of powdered colour adsorbent (15), which may also be activated carbon, to produce a treated liquor (18) low in dissolved organic matter and colour, and the spent powdered colour adsorbent (19) is preferably regenerated (37) and re-used.

Abstract: The operation sensor of a steam trap is used for judging the operating condition of a steam trap used in various installations using a steam and consists of an oscillation detection portion (1) and an operation processing portion (50) for operation processing the signals detected by the oscillation detection portion and outputting the results. The detection portion (1) includes a detection needle (2) brought into contact with an object of detection at a predetermined pressure urged by a flexible member and detecting mechanical oscillation of the detection object resulting from the steam flow and condensation flow in the object, an oscillation plate (21) for generating ultrasonic oscillation by the mechanical oscillation detected by the detection needle (2), an oscillation sensor (16) disposed so as to oppose the oscillation plate (21) and converting the ultrasonic oscillation to an electrical signal and a circuit substrate (20) including an amplification circuit for suitably amplifying the output from the oscillation sensor (16) and transmitting it to the outside. The operation processing portion (50) includes memory (M) for storing data corresponding to steam traps of various types inclusive of the detection object, a central processing unit (CPU) for performing operation by comparing the output of the detection portion transmitted from the detection portion (1) with predetermined data obtained selectively from the stored data of memory (M) and output portions (D; S) for displaying the result of operation by the central processing unit (CPU) and/or generating an audible output with an audio frequency. The operation sensor includes a temperature sensor (10) added to the tip of the detection needle (2) of the detection portion and can detect the temperature and/or steam pressure of the detection object. Accordingly, the operating condition of the steam trap can be judged more accurately.

Abstract: The toothbrush having a block handle (14),  which  is  hollow and is divided into two parts  pivotally  openable  to  receive  a tooth paste tube (9), and a block head section  (1)  implanted  at its front head (2) with bristles and provided with  a  tunnel  (3) for passing toothpaste  to  extrude  from  a  mouth  (5)  openably covered by a slide plate (8) guided in a groove  (7),  includes  a roller (21) having geared shaft ends (23,23a) projecting  on  both the sides to engage with the gear teeth provided on the side edges of the lower half part of the handle (14) to  be  driven  by  hand manipulation to drive the roller for squeezing the paste  tube  to extrude the paste out for use.

Title: Process for making oriented electrical steel sheet
Inventor: CHA SANG-YUN
IPC: C21D8/12
Filed: 1991-07-19
Granted: 1993-06-09
Abstract: The oriented electric steel plate having high  magnetic  flux density and good iron loss property is prepared by (a) making  the silicon steel slab into the oriented electric steel plate  by  the conventional method  including  rolling,  cleaning  and  annealing etc., (b)  forming  scratches  on  the  surface  of  the  oriented electric steel plate by laser or a  knife  to  finely  divide  the magnetic domain, and (c) oxidation annealing for forming the oxide layer around scratches at 700-1050 deg.C for 10 sec. - 5  hrs.  in moisture, oxygen, nitrogen or oxygen-nitrogen mixed atmosphere.

Title: Fabricating method of mesfet
Inventor: SHIN JIN-HO
IPC: H01L21/335
Filed: 1991-09-19
Granted: 1995-02-02
Abstract: The method includes the steps of forming a buffer layer (2), a channel layer (3) and a cap layer (4) on the substrate (1) to etch the layer (2) in a mesa structure forming a surface pasivation film (5) thereon to remove the film (5) on the source and drain formation area to form a source and drain metal region, selectively removing the portion between the source and drain regions to the layer (3) to form a 1st gate window (L1), forming an insulating layer on the side wall of the gate window, etching the channel layer (3) by using the side wall and a photoresist film (9) as a mask, and depositing a gate metal (8) to remove the photo-resist film (9) and the gate metal portion on the film (9) to form a gate, thereby using the sidew wall to obtain a short gate of 0.3-0.5 micron.

Title: Method of drive control for elevator
Inventor: CHON SANG-HO
IPC: B66B1/18
Filed: 1991-11-04
Granted: 1993-09-23
Abstract: The method is for compiling data, setting or resetting  flags and resetting the flag (DSK) at the moment of  ON  of  the  switch (ATT S/W) or the flag (DSK-ATT)  being  reset,  setting  the  flag (DSK) in the case of the  flag  (DSK-ATT)  being  set,  setting  a parallel driving mode when the flag (DSK) is set in order to  find the conditions for the parallel operation setting a manual driving mode finally.
