Title: Tuning circuits of broadcasting signal
Inventor: LEE KI-RYONG
IPC: H03J3/20
Filed: 1986-03-31
Granted: 1989-07-19
Abstract: The circuit for constant receiving sensitivity of the broadcasting signal comprises an antenna (1), a filter (2), synchronizing units (3,4,5), a high frequency amplifying unit (6), a local oscillator unit (7), a mixer (8) and a booster (9).  The booster combined with the synchronization circuit is switched with a selection switch (SW) according to the intensity of the broadcasting signal.  The switch connects to the booster to compensate the low signal for the weak area of the signal, but to the synchronisation circuit directly for the strong area of the signal.

Title: Injection molding method and apparatus of thermoplastic resin
Inventor: MAUS STEVEN M
IPC: B29C45/66
Filed: 1987-05-04
Granted: 1994-10-24
Abstract: Method and apparatus for injection compression molding of thermoplastic parts. A preferred apparatus (100) includes a platen assembly 106, a toggle clamp assembly 102, a screw injection assembly 101, a hydraulic system suitable for providing power to the toggle clamp assembly 102 and the screw injection assembly 101, and a control system 88 for operatively controlling the various hydraulic devices associated with the molding apparatus. The platen assembly 106 provides for a plurality of variable-volume mold cavities 7. In one embodiment, enlarged mold cavities 7 receive plasticized resin from the screw injection assembly 101, and compression of the injected resin is provided by the toggle clamp assembly 102. In another embodiment, the platen assembly 106 includes a floating die assembly wherein pressure created by injected resin causes die inserts 5 and support pillars 15 to slide relative to a molding plate 74. Compression in this embodiment is also preferably provided by the main toggle clamp assembly 102. Preferably, the toggle clamp assembly 102 provides multiple-stage compression of the resin to first redistribute the resin and vent the cavities and, second, compress the resin to compensate for cooling-induced shrinkage thereof. In the multiple cavity embodiment, because all cavities 7 are equally compressed simultaneously, control of the molding process and balancing of the mold are readily accomplished. The method and apparatus are particularly well suited for molding optical lenses and disks. Printed circuit substrates can also be molded thereby.

Abstract: A domed or conical sieve surface trapping solids from cooling water approaching a heat exchanger is periodically cleaned by applying suction upstream of the sieve to successive sector areas from a coaxial nozzle rotating over the sieve surface. The sieve sectors are defined by projecting radial webs. Gaps between the sector edges and the rotating nozzle are bridged by flexible sealing strips of whidth not less than the gap itself. Lips may be affixed to the webs or to the radial side walls of the suction nozzle. Webs may be combined with a continuous ring to form a portable integral framework.

Title: Fuel controlling system for internal combustion engine
Inventor: NAKAMOTO KATSYA
IPC: F02D41/24
Filed: 1987-12-24
Granted: 1990-09-24
Abstract: The fuel controlling system for an internal combustion engine has an AN detector for sensing a detected output of an intake air quantity in a section of a predetermined crank angle. An AN calculator corrects the output of the AN detector and a revolution detector senses the number of revolutions of the internal combustion engine. When the output of the revolution detector is below a predetermined value and that of the vehicle speed detector is within a predetermined range, this condition is defined as a very low speed mode. The constant in the correction processing is changed according to whether the vehicle is in the very low speed mode or not to control the quantity of fuel to be fed to the engine.

Title: Process for the continuous bulk production of high impact vinylaromatic (co)polymers
Inventor: BUONERBA CLAUDIO
IPC: C08F279/00
Filed: 1990-05-24
Granted: 1999-05-15
Abstract: Described is a process for the continuous bulk production of high impact vinylaromatic copolymers in which a vinylaromatic monomer, an optional vinyl-cyanide comonomer, a rubber, a part of a diluent solvent and a catalyst are premixed at a temperature below 100 DEG C and fed to an agitated tubular plug-flow reactor which is divided into several stages or zones. The excess mixture is recycled to the premixer and the remaining portion of the diluent solvent is injected in the top of the reactor to prevent the formation of incrustations. In the first zone of the reactor, the temperature and the residence time of the mixture are controlled so as to halve the catalyst lifetime. The polymerization is continued in the subsequent zones of the reactor until at least 40% by weight of solids have been formed.

Title: Metal substrate of improved surface morphology
Inventor: HARDEE KENNETH L
IPC: C23F1/00
Filed: 1990-06-29
Granted: 1999-06-15
Abstract: A metal surface is now described having enhanced adhesion of subsequently applied coatings. The substrate metal of the article, such as a valve metal as represented by titanium, is provided with a highly desirable surface characteristic for subsequent coating application. This can be initiated by selection of a metal of desirable metallurgy and heat history, including prior heat treatment to provide surface grain boundaries which may be most readily etched. In subsequent etching operation, the surface is made to exhibit well defined, three dimensional grains with deep grain boundaries. Subsequently applied coatings, by penetrating into the etched intergranular valleys, are desirably locked onto the metal substrate surface and provide enhanced lifetime even in rugged commercial environments.

Title: High power amp for ultra high frequency band
Inventor: CHOE DU-HON
IPC: H03F3/20
Filed: 1992-06-30
Granted: 1994-11-22
Abstract: The high power amplifier has an SSPA structure for extremely high frequency (EHF) band by using a micro-strip line. The amplifier comprises a conductor structure (26), an etched strip-line (16) in front of conductor layer of dielectric board (12) having low permittivity, a micro-strip line board (10) with a back conductor layer (14), an etched ground pattern (32) in horizontal direction of the etched strip-line. And the back conductor of the micro-strip line is located on the conduction structure (26).

Title: A production method of color filter for liquid crystal display
Inventor: KWON BYONG-IK
IPC: G02B5/20
Filed: 1992-08-14
Granted: 2000-11-15
Abstract: PURPOSE: A manufacturing method of color filters for an LCD is provided to be capable of enhancing the optical shielding efficiency of a black matrix and the brightness of the LCD by electroplating color agents on the black matrix. CONSTITUTION: A black matrix(2) is patterned on a transparent insulating substrate(1) and then a transparent conductive layer(5) is formed by a sputtering method. A photoresist polymer is coated on the conductive layer(5) to pattern a color electroplate portion and then red color agent is electroplated. The photoresist polymer is removed and then heat treatment of 200-0250 deg.C is performed. Above steps are repeated for electroplating of green color agent. Red color agent is electroplated without coating the photoresist polymer after the green and red agents are electroplated. (f) a transparent protecting film(4) is formed and then a liquid crystal drive electrode(5A) is formed.
