Patent KR-830007888-A (KR)
IPC: H05B7/08
Filed: 1981-11-26
Abstract: The invention concerns an electrode for arc furnaces, especially for electrosteel production, comprising a metallic liquid-cooled upper shaft (1) and an exchangeable lower active portion (2) of self-consuming material, particularly graphite, whereby a securing means is provided which is electrically insulated against the current-conducting components (11) of the shaft (1) and said securing means detachably connects the shaft (1) with the active portion (2) as well as holding the contact surfaces of the active portion (23) pressed against the contact surfaces (14) of the current-conducting components (11) of said shaft. To further develop an electrode of this type, which also provides the possibility of rapid and simple disconnection or connection with respect to the shaft (1) and the active portion (2) with a simple design, especially of the area of the active portion on the connection side, the securing device is designed as a clamping means (40; 60) which takes direct effect on the upper end of the active portion (2) in such manner that the clamping force essentially pressure-loads the material of the active portion (2), whereby the physical properties of the material of the active portion (2) are so exploited that no complicated designs are required on the connection side for said active portion (2).

Abstract: A torque wrench having a shaft with a tool head at one end a handle at the other end. The handle is supported on a lever system having a first and a second two-armed lever. One arm of the first lever engages one arm of the second lever. The handle is supported at two points on the other arm of the first lever and the other arm of the second lever. The other arm of the first lever engages a force sensor, which is attached to the shaft. The levers are dimensioned such that the measuring force acting upon the force sensor, when an applied force acts on the handle, is independent of the point of application of the applied force and is always proportional to the torque exerted about the axis of rotation of a tool.

Abstract: Photosensitive compositions containing phenolic resins and diazoquinone derivatives capable of being employed as photoresists in the formation of high-resolution patterns in the manufacture of integrated circuits. 
<??>These compositions exhibit a better contrast and a better selectivity by virtue of the addition of small quantities of a condensed polycyclic aromatic sulphonic or carboxylic acid in the form of the free acid and/or of an ammonium salt and/or of an acid halide, the cation of the ammonium salt having the formula 
<IMAGE>
 in which R1, R2, R3 and R4 = hydrogen, C1-C4 alkyl or C1-C4 hydroxyalkyl. 
<??>The process of formation of negative patterns comprises the following stages: (a) covering a substrate with the photosensitive composition, (b) exposure according to the image to an ultraviolet radiation, (c) treatment of the exposed composition with a silicon compound in such a way that the silicon compound is selectively absorbed into the irradiated parts and (d) development by a dry route in order to remove selectively the unirradiated parts.

Patent KR-910005674-A (KR)
IPC: H04H1/00
Filed: 1990-08-08
Abstract: A method and apparatus (10) for determining the channel of a plurality of predetermined channels to which a remotely controlled receiver (12) is tuned. A viewer transmitter device (24) includes a keyboard (26) for receiving viewer entered selections and a remote transmitter which transmits infrared, ultrasonic, radio frequency or other radiated control signals for each of the viewer selections. A receiver device (28) in a channel detection system (10) receives a signal in the selected transmission medium, and immediately signals a jamming device (44) to broadcast interference which precludes the remotely controlled receiver (12) from identifying and acting upon the transmitted control signal. The receiver device (28) applies the received signal to a processor device (30) that performs a stored program to determine if the received signal corresponds to a transmitted control signal from the viewer transmitter device (24) and, if so, to identify the channel to which the monitored remotely controlled receiver (12) is to be tuned. An associated memory device (52) is used for storing the identified channel reception data. The processor device (30) identifies the user selection and either applies a corresponding control signal to a second transmitter device (48) which transmits a control signal of sufficient strength to overcome the interference, or instructs the jamming device (44) to cease the broadcasting of interfering signals. In either case, the remotely controlled receiver (12) will now receive and implement the viewer selection. The processor device (30) will periodically broadcast a command to the remotely controlled receiver (12) containing the last identified channel data to ensure that a viewer does not manually adjust the channel being viewed.

Patent KR-910011921-A (KR)
IPC: C08F4/6592
Filed: 1990-12-22
Abstract: The present invention relates to a solid catalyst suitable for polymerizing olefins in a heterogeneous process, the catalyst being obtainable by a process comprising (1) contacting a support containing MgCl2 and an electron donor (D1) free from labile hydrogen with an electron donor (D2) containing labile hydrogen, and (2) then contacting the solid resulting from (1) with a zirconium metallocene, optionally with an organoaluminium compound which is preferably an aluminoxane. The solid catalyst may be used as such in olefin polymerization, or in the form of a prepolymer comprising a (co-)polymer of ethylene, the solid catalyst and an organoaluminium compound. The (co-)polymer of ethylene produced with the solid catalyst or with the prepolymer has a narrow molecular weight distribution and a low zirconium content and is in the form of a powder with a high bulk density, preferably consisting of spheroidal particles with a narrow particle size distribution.

IPC: C22C29/18
Filed: 1989-09-20
Abstract: A powdered admixture of a boron, carbon, nitrogen or silicon derivative of a first metal selected from titanium, zirconium, hafnium, vanadium, niobium, tantalum, chromium, molybdenum and tungsten, a source of a second metal selected from said metals and, optionally, boron, carbon, nitrogen or silicon is, when subjected to densification conditions, partially reacted and converted to a hard, wear resistant material. Such a material, formed from an admixture of tungsten carbide and molybdenum subcarbide, contains tungsten monocarbide and at least one mixed tungsten/molybdenum carbide. This material has a Vickers hardness of at least 2200 kg/mm<2> measured using a 1 kg load. Articles formed from this material can be useful as, for example, nozzles in abrasive or nonabrasive waterjet cutting machines and various parts of wire drawing apparatus.

Abstract: CPU를 구비한 키입력에 있어서, 키가 입력되는 키입력부(51)와, 제어단(DIR)의 신호에 따라 상기 키입력부(51)의 입력 신호를 받아 들이어 키입력을 확인하되 일정시간 이상이 되면 무시하는 키입력 확인부(53)와, 상기 키입력부(51)의 키입력 상태를 표시하는 LED표시부(57)와, 제어단(G. DIR)의 신호에 따라 상기 키입력 확인부(53)의 확인 결과를 전송하는 전송부(55)로 구성되어 표준 DIR주파수를 선정하고, 상기 주파수 선정후 DIR듀티사이클을 선정하여, 상기 DIR신호로 부터 키 또는 LED인에이블 인가를 체킹한다. 상기에서 LED인에이블일 때 점등 및 소등하고, 상기 키인에이블일때 키입력인가를 체킹하며 상기 키입력이 아니면 상기 과정을 다시 실행하고 키입력이 있으면 표준 DIR"로우"시간의 리세트 동안 DIR를 로우로 세팅한다.

Title: 하이브리드 프리픽스 애더의 레이아웃상 폴딩방법 및 그의 회로
Filed: 1991-10-07
Abstract: 본 발명은 32비트 하이브리드 프리픽스 애더에서 캐리체인의 상위 두레벨에 존재하는 첫번째 및 두번째 블렉셀을 단지 캐리 발생값만을 생성하는 것으로 대치하여 첫번째 및 두번째 블랙셀에서 캐리전파 값을 생성하는 부분에다 SUN 셀에 필요한 반전기를 삽입하고 상기 셀들을 하위레셀의 빈 공간에 배치하여 레이아웃상 한 레벨이 줄이도록 폴딩하여 칩영역을 감소시키고, 팬 아웃의 수의 감소에 따른 속도 향상을 시키는 것이다.
