Title: Calling signal transmitting system
Inventor: DAKADO GENJI
IPC: H04M19/02
Filed: 1985-05-30
Granted: 1990-02-07
Abstract: The apparatus has a circuit for detecting a ring trip signal in response to an off-hook operation of the telephone set during a signal state of an intermittent ringing signal.  A circuit detects a loop signal in response to an off-hook operation during a nonsignal state of the intermittent ringing signal.  A logical OR gate circuit provides, as a status signal, a logical sum of the ring trip signal and the loop signal.  A circuit supervises the status signal.  When an incoming call is being received and the supervising circuit detects an off-hook state, it stops the transmission of a ringing signal to the telephone set.

Inventor: LUSOZ STANLEY J
IPC: C22C29/12
Filed: 1987-08-24
Granted: 1995-03-16
Abstract: The disclosure concerns self-supporting ceramic structures, including ceramic composite structures embedding a filler, and methods of making them. The ceramic structures comprise a polycrystlline material made by oxidation of a body of molten parent metal with an oxidant. The polycrystalline material has a first region substrate surmounted by a terminal region stratum which is integral with the first region. The terminal region stratum which is harder and of denser, finer crystalline structure than the first region substrate and is formed in a reaction stage subsequent to the reaction stage in which the first region of polycrystalline material is formed. Growth of the first stage is attained by by attenuating or interrupting the transport of molten parent metal to the first region under conditions which nonetheless leave or maintain therein enough oxidizable molten parent metal to form the polycrystalline material of the terminal region.

Abstract: This adjunct processor arrangement performs a centralized call screening function to provide computer port access security. Every call origination in the telephone switching system from a calling party (T100) to a protected computer port (130) is interdicted by the telephone switching system and routed to the adjunct processor (104). The calling party (T100) receives a series of prompts from the adjunct processor (104) to provide identification information, such as login, password, and voiceprint information. The adjunct processor (104) validates the identity of the calling party (T100) using this identification indicia and initiates a callback operation. The adjunct processor (104) disconnects the calling party (T100) from the connection, calls the calling party (T100) back and then uses the data call transfer capability of the telephone switching system to connect the calling party to the computer (113).

Title: Method of making a body with superconductive oxide body
Inventor: CHEN HO S
IPC: H01L39/24
Filed: 1989-01-10
Granted: 1992-07-06
Abstract: Disclosed is a broadly applicable method for making an article that comprises a superconductive oxide body, including a thin layer on a substrate, or powder particles. In a preferred embodiment, the method comprises forming a precursor melt and contacting at least a part of the melt with oxygen such that the concentration of oxygen in the part of the melt increases to a critical concentration, resulting in formation of the desired oxide, substantially without drop in temperature. The precursor melt comprises at least one metallic element M, and at least the part of the melt is at a temperature T, with Tm < T < To, where Tm is the freezing temperature of the melt and To is the melting temperature of the superconductive oxide. In an exemplary embodiment the melt consists essentially of Yb, Ba, and Cu in 1:2:3 atomic ratio, T is about 900 DEG C. A layer of superconductive oxide on a SrTiO3 substrate is formed by dipping the hot (900 DEG C) substrate into the melt, exposing the melt-coated substrate to oxygen such that oxygenation and solidification of the coating results, and furnace cooling the coated substrate in oxygen. The thus produced coating has composition YbBa2Cu3O9- delta  ( delta SIMILAR  2.1), is essentially single phase, strongly textured, has Tc of about 85K and Jc of about 3x10<4> A/cm<2>. An aspect of the invention is the fact that the precursor melt need not be stoichiometric. For instance, we have formed a layer of composition YbBa2Cu3O7 from a melt of composition Yb2BaCu. The ability to practice the inventive method with non-stoichiometric precursor melts makes it possible to produce Y-containing bodies (e.g., YBa2Cu3O7 films on a copper substrate). The inventive technique can produce compositionally essentially homogeneous material. It is readily adaptable ro produce ceramics (including high Tc superconductors) and other materials (e.g., AlN) in a variety of shaped (including wire, tape, and powders) by a variety of techniques (including continuous processing). The inventive method can also be used to form a superconductive bond between two pre-existing ceramic superconductive bodies.

Abstract: There is described a decoding method and decoder apparatus for non-binary BCH-codes. Upon reception for an input word, first a syndrome information is generated. From this, the key equation is set up and solved to yield an error locator polynomial sig(z) and an error evaluator polynomial w(z). Next, on the basis of polynomial sig(z), its formal derivative polynomial sig min (z), Euclid's algorithm is used for calculating two accessory polynomials b(z), c(z), such that b(z)sig(z) + c(z)sig min (z) = 1. From these, a Lagrangian polynomial L(z) is calculated which for any inversed error location value has the associated error symbol value. The error data thereupon can be calculated by evaluating the error locator polynomial and the Lagrangian polynomial.

Abstract: 스퍼터링된 타겟트와 전기적으로 함께 작용하고 진공될 수 있는 코팅 챔버에 배열된 자석들에 연결된 음극에 접속되는 교류전원으로 구성되고 코팅 챔버에 프로세스 가스 예를 들면 아르곤과 산소 같은 반응 가스를 투여할 수 있는 이산화규소와 같은 절연물에 의한 기판의 반응 코팅장치에 있어서, 공정을 안정적으로 유지시키고 단단한 절연피막을 만들기 위해 교류전원의 접지 안 된 두 출력점을 타겟트를 지지하는 음극에 연결시킨다. 코팅실에 있는 두 음극은 기판와 같은 간격을 두고 마주한 진공 챔버에 나란히 설치된다.

Abstract: 본 발명은 반도체 광제어장치와 그 제조방법에 관한 것으로, 상기 광제어장치는 지지기판과 이 지지기판상에 배치되는 차광성박막 및 절연막을 매개로하여 상기 차광성박막상에 배치되는 반도체박막으로 이루어진 복합기판으로 구성되고, 스위칭소자는 트랜지스터와 광제어소자를 구동하는 투명전극으로 구성되어 상기 반도체박막상에 형성되며, 상기 스위칭소자와 투명전극은 전기적으로 상호 접속된 구조를 갖는다. 
     또한 상기 트랜지스터는 반도체박막에 내설되는 채널영역과 이채널영역의 도통을 제어하는 주게이트전극으로 구성되고, 상기 차광성박막은 채널영역을 사이에 두고 이를 덮는 구조로 형성되어 소위 배면채널의 발생을 효과적으로 방지하고 빛을 차단하게 된다.
