Title: Method and apparatus for processing food
Inventor: HAYASI DORAHIKO
IPC: A21C11/20
Filed: 1988-03-10
Granted: 1990-05-19
Abstract: An apparatus and method for measuring a uniform volume and weight of food. Screws are disposed at the bottom of a hopper and delivering feed having a rotating cylinder and vanes freely slidable in respective pairs of slots formed in the periphery of the cylinder. The delivering feed is disposed in a housing, and both ends of the vanes slidably contact the inner surface of the side wall of the housing to form compartments between each adjacent pair of vanes. The material is fed by screws and introduced into the compartment for measuring. Since the rotational speeds of the screw and cylinder are respectively controlled to introduce a sufficient amount of the material into the compartment, the density of the material in the compartment becomes uniform.

Title: Building tire
Inventor: KIM HYONG-SUN
IPC: B29D30/52
Filed: 1991-05-01
Granted: 1994-04-15
Abstract: The method for manufacturing a tire having more than two kinds of pitch units repeated on the tire tread surface, improves riding comfort by offering uniform wear of the tread and facilitates constant forming by reducing the resistance of small pitch group when forming the tire at the mold. The depth of grooves (2) between tread surfaces (2) becomes shorter when the pitch of the tire (1) is advanced from a large pitch (A) to a small pitch (C). The end section of the groove (3) becomes sharper or stepped by a rotio when the pitch is changing.

Title: Method of producing poly-arylene sulfide
Inventor: YU YONG-CHUL
IPC: C08G61/10
Filed: 1991-10-02
Granted: 1995-03-23
Abstract: Polyarylene sulfide is prepared by reacting polyhalagen substd. aromatic cpd. and emulsified alkali metal, where the emulsified alkali metal is prepd. by adding a azeotropic solvent with water into an organic acid amide solution of emulsified alkali metal having hydration water and heating to the azeotropic temp., then removing water at 100-220≰C (pref. 120-120≰C). Pref. the azeotropic solvent is hydrocarbon having 80-200≰C boiling point. The org. acid amide is N,N-dimethyl formamide, N,N-dimethyl acete amide, N-methyl pyrroliclone, or hexamethyl phosphoamide.

Title: Manufacturing method of polysilicon bipolar device with self aligned silicide electrodes
Inventor: KIM KWI-DONG
IPC: H01L29/73
Filed: 1991-11-25
Granted: 1995-02-11
Abstract: The method includes the steps of sequentially forming a poly-Si film (1), an oxide film (2), a nitride film (3) and a poly-Si film (4) on the substrate; growing and etching an oxide film (6) to define a device size; forming a trench isolation region (7) and poly-Si electrodes (8,9,10), depositing and etching an LPCVD oxide film thereon to expose the poly-Si films (4,8) to form a trench isolation oxide film (12) to remove the film (4) to form an unactive base electrode (25) with boron doping, growing an oxide film (13) on the electrode (25); removing a nitride film (3) to form diffusion layers (14,15,16,17), and forming a self aligned silicide layer (18) and metallic wirings on the electrode (25,26,27); thereby reducing the parasitic resistance component.
